NorthWestern Energy Issues Statement About Menno House Explosion

web@northwestern.com — Tue, 24 Aug 2010 15:51:52 GMT

Huron, S.D. – August 24, 2010 – NorthWestern Energy, working in conjunction with local officials, is in the process of investigating the circumstances surrounding a house explosion in Menno, South Dakota, last night.

NorthWestern Energy was called by the Menno fire department last night regarding a house explosion that occurred at 115 Park Street in Menno around 10:50 p.m. NorthWestern Energy crews responded to the emergency and shut off electricity and natural gas service to the scene and to two neighboring residences.

“All of us at NorthWestern Energy extend our deepest sympathy to the family of the deceased and to the friends and neighbors who’ve been touched by this tragedy,” said President and CEO Bob Rowe. “Menno, like so many of the towns we serve, is a close-knit community, and any incident such as this affects everyone.”

NorthWestern has reached out to several governmental agencies to notify them of the incident, including the South Dakota Public Utilities Commission and the Department of Transportation.

The company will assist the ongoing investigation to help determine the source of the natural gas. NorthWestern's initial tests, conducted within hours of the explosion, indicated that the gas was properly odorized and that there was no significant presence of natural gas in the soil around the house, which suggests that the leak occurred inside of the house.

NorthWestern Energy Updates Information About Columbia Falls House Explosion

web@northwestern.com — Wed, 14 Jul 2010 12:00:06 GMT

Butte, Mont. – July 14, 2010 – NorthWestern Energy today released the findings of the investigation into the May 6 natural gas explosion that destroyed a family home and claimed the life of long-time gas serviceman, Jim Hilton.

The house that exploded was on the southwest corner lot at the intersection of 2nd Avenue West and 12th Street West in Columbia Falls. 2nd Avenue West runs north-south on the east (front) side of the house and the gas main runs underneath the street. Two service lines branch perpendicularly off of the main. The service line to the house that exploded tees off of the main and runs westerly to the meter on the south side of that house. ELM Locating and Utility Services had located and marked the service line to that house the previous week.

A second service line (the line that was damaged) tees off of the main and provides service to the neighboring house to the west. That line runs westerly parallel to 2^nd Avenue West on the north side of the house that exploded. ELM had reportedly not performed a locate for that service line prior to the accident.

The subsequent accident investigation established that while using a backhoe to dig a hole for a street light pole, the Flathead Electric Cooperative backhoe operator snagged a ¾ inch gas service line, pulling it off of its welded connection to a service tee on the nearby gas main. Gas from the broken connection migrated through the soil along the path of a sewer line and into the basement of the house, where it found an unidentified source of ignition and exploded. Investigators for all of the interested parties conducted initial site documentation and surveying in the days immediately following the accident.

On May 27, 2010, the investigators reassembled at the site and cleared debris from the basement of the house that had exploded in order to conduct gas migration tests using compressed air to identify the general path of the gas from the broken gas line near the street into the basement of the house. Those tests indicated that the gas escaping from the broken weld had generally followed the soil around the sewer line from the leak to the foundation of the house that exploded.

After completing the gas migration testing, the investigators began excavating the gas piping where the service line for 218 12^th Street West connected to the gas main line near the southwest corner of the intersection. Most of the gas service line was exposed that day, but the area where the service line connected to the gas main was left buried and covered with a tarp overnight to protect it from the elements. The ground above service line/gas main connection was unburied the next day to expose the service line connection to the main. Visual inspection of the exposed line confirmed that the service line had been torn off of the service tee on the gas main line when the service line was snagged by the backhoe on May 6, 2010.

The fracture was documented in place and then digging continued in order to remove and preserve the damaged sections of gas main and service line. After the damaged sections of gas piping had been removed, additional non-destructive documentation of the fracture surfaces was performed. The basement and exposed sewer lines associated with the house that had been destroyed were documented, and the interior gas piping and boiler collected from the house debris earlier that day were documented and retained. Soil samples were also taken adjacent to the leak site.

“The investigation confirmed that gas migrated from the separation into the home where it exploded,” said NorthWestern Energy’s President and CEO, Bob Rowe. “While the investigation has ended, the lengthy healing process continues for the Langton and Hilton families and for everyone else who was touched by this tragedy. On behalf of NorthWestern Energy, I thank the first responders who worked closely with our great Flathead Valley-based crew, and I thank the community for its support of our employees and of Jim Hilton’s family during a difficult time.”

NorthWestern Energy Warns Customers About Telephone Scam

web@northwestern.com — Fri, 09 Jul 2010 14:41:39 GMT

Butte, Mont./Huron, S.D. – July 9, 2010 – NorthWestern Energy learned today of a scam that implicates the utility and warns its customers to be aware of such illegal schemes.

Earlier today, an alert NorthWestern Energy customer received a telephone call scammer telling her that she had been selected to participate in a drawing to win a Mercedes Benz vehicle because she “pays her utility bills on time.”

The Lewistown, Mont., resident was too suspicious to provide any information and hung up immediately. She promptly reported the call to NorthWestern Energy, her utility. The customer said the con artist claimed to work for a company in Washington and that the contact information was made available because of her payment history.

The scammer didn’t refer to NorthWestern Energy by name and instead used the generic phrase “your utility” during the call, which is why the company reminds everyone to be suspicious of any telephone or internet solicitation offers particularly if they ask for personal information including credit card or bank account information.

Customers with questions or concerns about potential scams should contact their state’s Consumer Affairs department for more information.

NorthWestern Energy Granted Interim Rate Relief

web@northwestern.com — Fri, 09 Jul 2010 11:50:31 GMT

Sioux Falls, S.D. – July 9, 2010 – NorthWestern Corporation d/b/a NorthWestern Energy (NYSE: NWE) announced today that the Montana Public Service Commission (“MPSC”) granted an interim rate increase, consistent with NorthWestern’s October 16, 2009 Application for Authority to Establish Increased Natural Gas and Electric Delivery Service Rates and Implement Allocated Cost of Service and Rate Design Proposals (the “Application”), for electric delivery revenues of $12,395,640, on a uniform basis, and for gas delivery revenues of $1,361,517, on a uniform basis, effective July 8, 2010 (the “Interim Order”).

The MPSC’s order indicated that if the final order in this Application has a revenue requirement which is lower than the revenue requirement contained in the Interim Order, the difference will be rebated to customers with interest at 10.75 percent, NorthWestern’s last approved return on equity. In addition, interim approval of any matters in this proceeding should not be viewed as final endorsement by the MPSC of any issues, calculations, or methodologies approved in the Interim Order.

NorthWestern expects to reserve the revenues collected as a result of the Interim Order for accounting purposes in accordance with Generally Accepted Accounting Principles, pending the issuance of a final order on this matter.

Neither the Interim Order, nor any other Application decision, will have any consequence on the 2010 earnings guidance previously provided by NorthWestern because that guidance specifically excluded any effect of the pending Application.

NorthWestern expects a final decision on the Application during the fourth quarter of 2010.

NorthWestern Energy Recognizes June 10 as National Pipeline Safety Day

web@northwestern.com — Mon, 07 Jun 2010 14:34:34 GMT

Butte, Mont. – June 7, 2010 – NorthWestern Energy is joining the Pipeline Association for Public Awareness (PAPA) in recognizing and promoting June 10 as National Pipeline Safety Day.

In 2009, the U.S. House of Representatives and the House Transportation and Infrastructure Committee passed H. Res 484, establishing June 10 as National Pipeline Safety Day in recognition of the tenth anniversary of the Bellingham petroleum pipeline explosion that killed three young people. H. Res. 484 stresses that “greater awareness of pipelines and pipeline safety can improve public safety,” and encourages individuals, state and local governments and pipeline safety stakeholders to work together to create greater public awareness of pipeline safety.

“At NorthWestern Energy, we work methodically and thoroughly to ensure the integrity of our systems. We want the communities in which we live and work to know what we are doing to protect the safety of our neighbors and the environment,” said Bob Rowe, President and CEO of NorthWestern Energy.

Over the course of the last 10 years, Congress has passed two major legislative initiatives directing the primary pipeline oversight agency, the U.S. Department of Transportation, Pipeline and Hazardous Materials Safety Administration (PHMSA) to enact stronger measures to ensure steps are taken to maintain and protect the integrity of the pipeline infrastructure used to transport and deliver the nation’s energy supply. Pipeline operators, like NorthWestern Energy, regulatory agencies and other stakeholders have also carefully reviewed the existing regulatory requirements to determine whether additional safety measures were needed to ensure the safety of the communities in which pipelines operate.

To improve safety, NorthWestern Energy has focused on three measures over the past decade: (i) examining and evaluating the actual condition of a pipeline, (ii) educating people as to the purpose and location of pipelines in their community and (iii) informing everyone as to the measures they can take to prevent causing damage to underground facilities like pipelines.

“Managing the integrity of our pipeline system is a top priority at NorthWestern Energy. We constantly examine and evaluate the operations of the pipeline and take prudent and thorough steps to protect not only the pipelines but also the individuals who live and work around our buried lines,” said Rowe.

NorthWestern Energy undertakes significant efforts to remind people of the presence of pipelines in their community while also promoting pipeline safety through in-person meetings, mailing and training sessions. The company provides safety and awareness information on a wide array of topics, but specifically on the purpose and importance of pipelines, the general location of facilities, and what pipeline markers look like. NorthWestern Energy also provides information on how to recognize and respond to a potential or known pipeline related emergency. In addition, the company coordinates training for emergency personnel on the steps they need to take to protect life, property, and the environment in the event of a pipeline incident.

One of the main principles of pipeline public awareness is the “call before you dig” message. Under state and federal law, anyone excavating – including digging with a shovel - is required to call your local one-call center, or 8-1-1 before beginning to dig. You must then wait at least two working days before you can dig. This allows time for your local one-call system to notify underground facility owners of your intent to excavate. This activity is done to prevent damage to the facility and ensure the safety of the excavator. The service is free to anyone.

Damage prevention measures like promoting the “call before you dig” or “know what’s below” messages are crucial for every pipeline operator, including NorthWestern Energy. Damage caused by excavators is the leading cause of pipeline accidents. These incidents are preventable if people would simply call
8-1-1, wait the required time and respect the marks.

Barry O’Leary, safety director at NorthWestern Energy emphasized, “Pipeline safety is everyone’s responsibility. The pipeline industry takes steps each day to monitor and evaluate the operations and risks to its system. At the same time, excavators and communities need to respect buried pipelines and know how to recognize the presence of a pipeline, what do to before digging, and how to respond in the event of an incident. Education is key to both operators and the public.”

While pipelines have a good safety record relative to the tremendous volumes of products they carry, pipeline accidents can and sometimes do occur. For that reason, NorthWestern Energy urges everyone to become aware of pipelines in their communities and to understand how to prevent, recognize and respond to pipeline emergencies.

NorthWestern Energy Updates Information About Columbia Falls House Explosion

web@northwestern.com — Mon, 10 May 2010 15:49:36 GMT

Butte, Mont. – May 10, 2010 – NorthWestern Energy, working in conjunction with local officials, is continuing to investigate the circumstances that led to a house explosion last Thursday in Columbia Falls, Montana. Gas entered the house and exploded after an underground gas service line was struck with a backhoe by the local electric cooperative.

The contents of the home and the site are in control of the homeowners and their insurance company. The area around the site, including a portion of 12^th Street West, has been fenced and secured during the investigation. All of the neighbors can access their houses off of the portions of the street that will remain open.

Investigators for the various interested parties will reconvene in about a week and a half to conduct a leak test and define the path of the gas into the house before excavating the service line and the main.

NorthWestern Energy Updates Information About Columbia Falls House Explosion

web@northwestern.com — Fri, 07 May 2010 13:56:03 GMT

Butte, Mont. – May 7, 2010 – NorthWestern Energy, working in conjunction with local officials, is in the process of investigating the circumstances that led to a house explosion in Columbia Falls, Mont., yesterday afternoon.

On May 6, shortly before 2 p.m., NorthWestern Energy received a call regarding a hit gas line in Columbia Falls. A Flathead Electric Cooperative utility crew had struck a three-quarter inch steel line while installing a power pole. The fire department arrived at the scene and conducted an evacuation procedure. The NorthWestern Energy crew responding to the call of a hit gas line was on site and in the process of initiating repairs when the explosion occurred between 3:50 and 3:55 p.m. Initial investigation indicates that the NorthWestern employees on scene acted in accordance with all standard safety procedures and protocols.

Fifty-three year-old Jim Hilton, a journeyman serviceman who had worked at NorthWestern Energy for almost 15 years, was found in the debris from the blast and was non-responsive. EMTs attempted to resuscitate Jim, but were unsuccessful.

The house that exploded was near the damaged service line but was not served by the line. Today, a Missoula-based crew will restore natural gas service to the neighboring houses. Internal and independent investigators also will be back on the scene today to continue the investigation.

“Our hearts go out to Jim’s family, friends and co-workers,” said Bob Rowe, NorthWestern Energy President and CEO. “Jim was a dedicated professional with a stellar safety record and was known for going above and beyond the call of duty on behalf of our customers in the Flathead. He will be sorely missed.

“Our Kalispell team were professionals in staying focused on finishing the work, while also pulling together to support one another. There aren’t many things tougher than losing someone you’ve worked next to and depended on for years. We will do everything we can to support Jim’s family and coworkers through this very difficult time.”

NorthWestern has contacted several governmental agencies including the Montana Public Service Commission, OSHA and the Department of Transportation to notify them of the incident.

Forbes.com Names NorthWestern Energy as one of its Top "100 Most Trustworthy Companies" in America

web@northwestern.com — Thu, 06 May 2010 10:50:28 GMT

Butte, Mont. – May 5, 2010 – Recently, Forbes.com named NorthWestern Energy as one of its top “100 Most Trustworthy Companies” in America. The list, compiled by Audit Integrity, recognizes the nations’ top 100 companies that have consistently demonstrated transparent and conservative accounting practices as well as solid corporate governance and management.

“It is a great credit to the integrity of our employees and also to our Board of Directors,” said Bob Rowe, president and CEO of NorthWestern Energy.

The evaluation penalizes companies for unusual or excessive executive compensation, high levels of management turnover, substantial insider trading relative to their corporate peers or high levels of short-term executive compensation, which encourages management to focus on short-term results. Good housekeeping practices leave companies better prepared to handle an economic downturn, especially one as severe as right now.

"As a publicly-traded utility that is one of the largest companies in our region, we are in a position of trust.” explained Rowe. “I’m particularly pleased because the analysis recognizes current NorthWestern practices that make us among the most trustworthy companies from a corporate governance perspective.”

In light of events like corporate scandals, bankruptcies, and the recession that have made news in recent years, Forbes had set out to identify the most transparent and trustworthy businesses that are traded on U.S. stock exchanges, based on an evaluation of 8,000 companies. To do so, it turned to Audit Integrity, an independent financial analytics company based in Los Angeles. Audit Integrity looks beyond the raw data on income statements and balance sheets to assess the true quality of corporate accounting and management practices. As early as August 2005, Audit Integrity's proprietary rating system signaled potential problems at Lehman Brothers. In December of 2005, it gave American International Group a significant downgrade. Last year it flagged the Chicago management consultancy Huron Consulting Group several months before the company announced it was restating its financial statements for three fiscal years and its chief executive, chief financial officer, and accounting chief resigned.

For the fourth year, Audit Integrity has provided Forbes with a list of companies that are at the other end of the spectrum from the beleaguered firms that make so many of today's headlines. Audit Integrity finds that its 100 Most Trustworthy Companies have consistently demonstrated transparent and conservative accounting practices and solid corporate governance and management. The companies that make this list “are the good guys," said Jack Zwingli, the chief executive of Audit Integrity. "They've consistently shown accuracy and transparency in their financial reporting."

According to Forbes.com, to qualify for the top 100 list, a company must have the following:

Market caps of $200 million or more at the time Audit Integrity prepared the list
Accounting and Governance Risk (AGR) ratings of "conservative" or "average" for each of the last four quarters
No amended filings with the Securities and Exchange Commission or material restatements over the last year
A high rank in Audit Integrity's Equity Risk Ranking, which indicates a positive forecast for equity returns
Audit Integrity sorts its 100 Most Trustworthy Companies into three groupings according to market capitalization. With its market cap of approximately $950 million, NorthWestern Energy is recognized on the Small-Cap list.

Forbes recognized only a handful of other utilities including Avista, Nicor, Hawaiian Electric Inds, Ameren, Consolidated Edison, Idacorp, El Paso Electric, and Central Vermont Public Service.

Rowe concluded, “This further emphasizes NorthWestern’s mission to work together to create value for our customers, communities, employees and investors.”

NorthWestern Energy Files Annual Townsend Propane Supply Cost Adjustment

web@northwestern.com — Wed, 05 May 2010 12:15:22 GMT

Butte, Mont. – May 3, 2010 – NorthWestern Energy announced today that it has made its annual filing with the Montana Public Service Commission (MPSC) to adjust propane supply costs in Townsend, Montana, on an interim basis June 1, 2010, pending final commission approval.

If approved, propane customers in Townsend will pay the equivalent of $1.31 per gallon during the summer season and $1.41 during the winter heating season for the fuel they consume. That compares to the previous rate of $1.01 and $1.08, respectively. Propane supply costs are adjusted on an annual basis based on the contracted market supply price for propane along with any over or under collection of the previous year’s contract. During the last nine month period beginning on September 1, 2009 and ending on May 31, 2010, NorthWestern Energy under collected $64,343, which it proposes to amortize and collect over the next annual tracker period. NorthWestern Energy does not earn a profit on the supply cost, and the current delivery and service charges are not affected by this filing.

The MPSC has assigned Docket Number D2010.4.44 to this case. The MPSC telephone number is (406) 444-6199. The Montana Consumer Counsel is a state agency established by the Montana Constitution to represent Montana public utility and transportation consumers before the MPSC, state and federal courts and administrative agencies in matters concerning public utility regulation. The counsel’s telephone number is (406) 444-2771.

NorthWestern Energy to Conduct Maintenance on Electric Transmission System

web@northwestern.com — Tue, 04 May 2010 08:30:51 GMT

Butte, Mont. – May 4, 2010 – NorthWestern Energy crews have begun performing routine annual maintenance on the 500 kV Colstrip Transmission System between Broadview and Townsend, Mont. This year’s work, scheduled to be complete by mid-May, includes the replacement of conductor spacers, or diamond-shaped brackets that keep the electric lines from inadvertently touching one another.

During this maintenance time, people in the area might see men and equipment on the transmission towers and traveling along the lines in spacer carts. The company has notified landowners in the area that NorthWestern Energy vehicles and equipment, as well as clearly marked contractor vehicles, will be accessing rights of way throughout this period. Helicopters also will be working in the area delivering material and providing support to the crews working on the towers and lines. NorthWestern Energy crews perform this work during daylight hours Monday through Friday and occasionally on Saturday or Sunday, weather permitting.

The company makes every effort to control the spread of noxious weeds by washing all vehicles and equipment daily prior to entering the right of way. Upon completion of the work, right-of-way technicians inspect the area and apply herbicides in order to minimize the potential spread of seeds.

Landowners with questions or concerns about right of way access should contact Roger Licht (406) 366-1580.

UPDATE 04/30/2010; 4:00 p.m. - NorthWestern Energy Updates Electric Outages in Montana

web@northwestern.com — Fri, 30 Apr 2010 16:45:01 GMT

Butte, Mont. – April 30, 2010 – Crews have made some progress to restore power to customers today, but approximately 2,000 customers are still without service in north central and central Montana.

Service has been restored to most of the rural communities in the Great Falls area, with some exceptions including Stockett, Neihart, Armington and Raynesford. However, there are still many scattered outages in communities throughout the area. In addition, customers that may be experiencing an outage but have not called to report the outage should call (888)-467-2669.

It is likely that some of these outages may be out of power for an additional 24-48 hours as a result of storm damage and limited access due to highway closures and heavy snow. Customers in these areas who may be in need of emergency housing assistance are asked to call the Red Cross at 1-800-272-6668.

As the snow and winds continue, additional customers may experience scattered outages. NorthWestern Energy encourages customers to report all outages, sagging or broken lines or downed poles by calling (888)-467-2669.

In addition, the company reminds everyone of the following safety tips:

If they see fallen or sagging electrical wires, assume it is “live,” and stay clear of the lines. Keep others away from wires and any other structures that may be energized. Call NorthWestern Energy or a local emergency service to report a downed or sagging power line.
Beware of fallen or broken branches and trees because they may have pulled an electric line over when they fell and could be energized.
Keep an emergency kit ready. Include flashlights, battery-powered radio, canned foods that require no cooking and fresh batteries. Remember that only non-electric land-line phones work during storms when power is interrupted so people should ensure their mobile cell phones are fully charged when storms are forecasted. Also, remember that some cell phone towers do not work at full power after losing an electric feed.
Use portable generators only if a licensed electrical contractor in accordance with all federal and state codes and local ordinances has properly installed them. Portable generators should not be connected directly to a structure’s wiring. Doing so may feed energy back on through electric lines and threaten the safety of crews working to restore an outage.
Shut off appliances and lights and unplug sensitive electronic equipment. Use a surge protector to protect sensitive electronic equipment such as televisions and computers.

UPDATE 4/30/2010; 11:00 a.m. - NorthWestern Energy Updates Electric Outages in Montana

web@northwestern.com — Fri, 30 Apr 2010 11:16:21 GMT

Butte, Mont. – April 30, 2010 – As a spring storm continues to bring heavy, wet snow and strong winds to north-central and central Montana, NorthWestern Energy reminds customers to call if they experience a power outage and to exercise extreme caution around downed or sagging power lines.

Crews have made some progress to restore power to customers overnight and this morning, but a significant amount of customers are still without service in North Central and Central Montana. Currently, high winds and impassable roads are hampering efforts to assess damage and restore service.

In Lewistown, approximately 300 customers mostly in the southwest part of town are still without power. The towns of Geyser and Merino are still without power due to transmission problems, and outages are reported in Stanford, Denton, and Geraldine. Outages are also reported in the areas in and around Wolf Creek, Craig, American Bar, Nelson, Hogback, York, Canyon Ferry, and White Sulphur Springs.

Service has been restored to most of the rural communities in the Great Falls area with some exceptions including Stockett, Belt, Monarch, Neihart, Armington, and Raynesford. However, there are still many scattered outages in communities throughout the area. It is likely that some of these outages may be out of power for an additional 24-48 hours as a result of storm damage and limited access due to highway closures and heavy snow. Customers in these areas who may be in need of emergency housing assistance are asked to call the Red Cross at 1-800-272-6668.

As the snow and winds continue, additional customers may experience scattered outages. NorthWestern Energy encourages customers to report all outages, sagging or broken lines or downed poles by calling (888)-467-2669.

Because of the widespread nature of this storm, NorthWestern Energy’s contact center is handling a large number of calls, which may create long on-hold times. Customers have several options available to them to avoid waiting on-hold by following the phone system instructions to leave a message or report an outage without talking to a customer service representative. The company appreciates customer’s patience as they wait to report a situation. In cases of life-threatening emergencies, individuals still should call 911.

Due to high winds, heavy snow and poor visibility and driving conditions, customers should be prepared for extended outages particularly in rural areas where forecasted conditions are expected to be severe. In addition, the company reminds everyone of the following safety tips:

If they see fallen or sagging electrical wires, assume it is “live,” and stay clear of the lines. Keep others away from wires and any other structures that may be energized. Call NorthWestern Energy or a local emergency service to report a downed or sagging power line.
Beware of fallen or broken branches and trees because they may have pulled an electric line over when they fell and could be energized.

Butte, Mont. – April 29, 2010 – As a spring storm continues to bring heavy, wet snow and strong winds to north-central and central Montana, NorthWestern Energy reminds customers to call if they experience a power outage and to exercise extreme caution around downed or sagging power lines.

Currently, all available NorthWestern Energy crews from throughout the state are working to restore power to an estimated 5,000 – 7,000 customers in central and north central Montana. As the snow and winds continue, additional customers may experience scattered outages. NorthWestern Energy encourages customers to report all outages, sagging or broken lines or downed poles by calling (888)-467-2669.

Most of the rural communities without power are located north and east of Great Falls and around Lewistown. There are scattered outages throughout the area.

NorthWestern Energy Kicks Off Bright Future Challenge on Earth Day

web@northwestern.com — Wed, 21 Apr 2010 09:38:57 GMT

Butte, Mont. – April 21, 2010 – In celebration of the 40^th Anniversary of Earth Day, NorthWestern Energy is kicking off a yearlong challenge to its customers. Residential electric customers in Montana and South Dakota are encouraged to accept the Bright Future Challenge and install compact fluorescent lamps (CFLs) in high use locations in their homes. Over the next year, the challenge is for NorthWestern Energy customers to join together and save 10 million kilowatt hours (kWh) of electricity by switching from traditional incandescent bulbs to CFLs.

Starting on Earth Day, Thursday, April 22, customers can sign up for the Bright Future Challenge at www.brightfuturechallenge.com and enter a yearlong contest for $10,000 in prizes. There are three gift card prizes offered that will be honored through a home improvement store in the area of the winning customers. First Prize is worth $5,000; Second prize -- $3,000, and Third Prize --$2,000. Customers accept the Bright Future Challenge and report the number of CFLs installed starting with Earth Day, 2010. While only one contest entry is allowed for each account, customers are encouraged to continue to update their information as they install more CFLs to help reach the 10 million kWh goal.

“The Bright Future Challenge will show how small actions by many add up to big energy savings,” said Bill Thomas, Manager of Regulatory Support Services. “We’re challenging our customers to replace about 200,000 incandescent bulbs with CFLs over the next year to save 10 million kWh. That’s enough electricity to power over 1,000 homes.”

CFLs use one-quarter of the electricity of a traditional bulb and last up to ten times longer. By shopping for CFLs with the 4L’s – Label, Light, Location, and Less Energy, customers can choose the right CFL for the right location and immediately start saving energy. Information about shopping for CFLs, the proper disposal of spent CFLs, along with other energy efficiency information is provided at the Bright Future Challenge Web site.

Customers without internet access may call the NorthWestern Energy Customer Contact Centers to enter the Bright Future Challenge.

Montana residential electric customers will receive a coupon in the mail to save $2 off the price of each CFL purchased at participating retailers. The coupon is valid from April 22 through June 13, 2010.

NorthWestern Energy provides a mix of energy efficiency and renewable energy programs under the Efficiency Plus (E+) umbrella. Rebates are offered for homes and businesses for installation of qualifying energy efficiency improvements. Energy audits are also available to qualifying customers whose home or business has not been audited in the past.

For customers that are interested in offsetting their electric usage with the environmental benefits of renewable energy generated in the Northwest, the E+ Green Power program is offered for as little as $2 a month. Incentives for qualifying renewable generation systems are available through the E+ Renewable Energy program.

Open Season Informational Meetings Pre-Registration Reminder

web@northwestern.com — Mon, 22 Mar 2010 16:30:38 GMT

Mountain States Transmission Intertie and
Montana Renewable Collector System

Butte, Mont. – March 22, 2010 – Potential bidders who haven’t registered yet to attend the upcoming informational meetings about NorthWestern Energy’s (NYSE: NWE) upcoming Open Seasons for two proposed electric transmission projects are reminded that they have until March 24 to complete the online pre-registration requirement.

Potential bidders interested in the Mountain States Transmission Intertie (MSTI) project can now pre-register on line at www.msti500kvos.com, while potential bidders on the Montana Renewable Collector System (MT-RCS) project should pre-register at www.mt-rcsos.com. Potential bidders interested in both projects must pre-register for each meeting separately.

Both meetings will be held at the Best Western Great Northern Hotel in Helena, Montana, on March 25, 2010. The Mountain States Transmission Intertie informational meeting will be held from 9 a.m. – 12 p.m. followed by the informational meeting on the Montana Renewable Collector System from 1:15 p.m. – 5:00 p.m.

The information meeting is open to those parties: who meet the definition of “Eligible Customer” set forth in NorthWestern’s FERC approved Open Access Transmission Tariff (“OATT”); those Eligible Customers who are capable of making Transmission Service or Interconnection requests in a manner consistent with and as defined in NorthWestern’s OATT; and those Eligible Customers that also meet other minimum credit and other criteria to be established by NorthWestern that are consistent with applicable regulation.   Eligible Customers will have the opportunity to ask questions and provide feedback to NorthWestern on the Open Season process.

Those pre-registering must meet the Criteria for Registration in order to receive access to the information presented in these Web sites and at the meeting. Those who meet the criteria but who will not be attending the meeting in person will receive information about a telephone bridge that will be available during the meetings.

The MSTI project is a 500kV AC transmission line between Townsend, Montana and Midpoint, Idaho. The approximately 430 mile line proposal is currently undergoing environmental review with the draft Environmental Impact Statement expected to be released in April 2010. MSTI is intended to facilitate the delivery of new sources of renewable energy, primarily wind energy, to customers in the West. Construction of MSTI is anticipated to begin in spring 2012 and placed into service in early spring 2015.

The proposed MT-RCS project is a series of up to five new 230kV generator lead lines that will originate in the high-quality wind regions of Montana that are currently under consideration for development, but the ultimate size and configuration will depend on the results of the Open Season. These lines would move energy from its origination to a new substation south of Townsend, Montana, where they would connect to both the existing 500kV Colstrip Transmission System and the proposed MSTI 500kV line.

Together and separately, the MSTI and MT-RCS projects will provide a key pathway for new regional generation opportunities, primarily from wind, to demand centers in the Pacific Northwest, the Desert Southwest and California.

Successful bidders in the Open Seasons will secure firm transmission rights and/or interconnection rights to deliver renewable energy to power markets in western states to comply with their Renewable Portfolio Standards.

NorthWestern Energy will conduct the Open Seasons in a transparent, non-discriminatory process. Any entity wishing to secure long-term, point-to-point transmission rights on MSTI and/or the interconnection rights on MT-RCS may submit proposals for consideration.

For those attending in person, the Great Northern Hotel has a block of rooms reserved. Please contact the hotel for additional information at (406) 457-5500. The hotel is located at 835 Great Northern Boulevard in Helena, Montana.   Questions may be submitted anytime to Dan Rapkoch, Project Communications Manager, at (406) 490-1895 or via email dan.rapkoch@northwestern.com.

web@northwestern.com — Thu, 25 Feb 2010 09:47:09 GMT

Huron, S.D. – February 24, 2010 – Beginning on March 1, 2010, NorthWestern Energy’s office in Brookings, South Dakota, will be at its new location at 1232 22^nd Avenue South. Construction is finished, and crews are moving in office furniture, computer hardware, operation tools, and equipment and putting the finishing touches to make the space operational.

“This is a very exciting time for our employees, and our customers will see extra convenience with our added space, parking access, and some new features,” said Mike Cameron – Brookings Area Manager. “For years, we have maintained two locations in Brookings with our office downtown and the shop on the southeast corner of the downtown area. We have outgrown both buildings, and our new location and the state of the art technology will enable our employees to better serve customers.”

The new building features 7,200 square feet of shop area that will house an operations employee office, construction equipment, vehicles, tools, work areas, and materials. The former shop, located on the 500 block of 1^st Avenue South, was 2,200 square feet and lacked necessities such as running water and restrooms.

The office area inside the new building is 2,400 square feet and features a large conference room, storage, office space, and a Customer Service Representative area where walk-in customers can handle business needs during office hours.

The property boasts several convenient parking spaces and a drop-off box for customers not needing to bring payments inside or to drop payments off after hours from a car window. A privacy fence on the west end will divide the exterior property where some outdoor storage needs will be served.

Office hours will be 8 a.m. – 5 p.m. Monday through Friday. An open house is being planned during the spring.

NorthWestern Energy Offers Tips for Choosing an Energy Efficiency Contractor

web@northwestern.com — Thu, 28 Jan 2010 14:25:28 GMT

Butte, Mont. – January 28, 2010 – NorthWestern Energy reminds Montana consumers to study their options carefully when selecting a contractor to perform energy efficiency work in their homes.

Increased attention to energy efficiency along with utility rebates and state and federal tax credits have more Montanans looking to installers to perform work in their homes. In addition, numerous new businesses selling energy efficiency products and services are entering the market. NorthWestern Energy customers should note that although the utility offers rebates for qualifying energy efficiency improvements, it does not endorse products or contractors.

“We encourage customers to make qualifying energy efficiency improvements in their homes and customer satisfaction and safety are important to us,” said Bill Thomas, NorthWestern Energy Manager of Regulatory Support Services. “That’s why we’re offering tips to help customers identify the contractor they are comfortable with to install measures for which NorthWestern Energy offers rebates.” The utility offers a list of Preferred Contractors who are licensed and insured, and who agree to follow the E+ program requirements as a start. “As with any investment in your home,” Thomas adds, “It’s a good idea to check credentials and shop around.”

When selecting a contractor, NorthWestern Energy offers the following tips:

Request bids from several contractors and compare the details of the job as well as costs.
Talk to friends and neighbors about their experiences with a contractor.
Ask all contractors to provide proof of their contractor’s license and insurance (e.g., worker’s compensation, property damage and personal liability).
Understand what you are buying: Is the language in the contract agreeable to you; what does the price include; how and when is payment due; what is the timeline for completion; and what warranty is provided for products and services provided.

NorthWestern Energy reminds customers that neither its employees nor its service providers conduct door-to-door calls on residential customers for energy efficiency programs. Additionally, Thomas reminds the public that NorthWestern Energy employees and its service providers carry company identification. Customers should notify NorthWestern Energy or law enforcement immediately if they witness suspicious individuals representing themselves as NorthWestern Energy employees or service providers. Customers may call NorthWestern Energy at (888)467-2669 to verify the identity of a NorthWestern Energy employee or service provider and the NorthWestern Energy activity provided.

Details about NorthWestern Energy’s E+ energy efficiency programs and rebates and more tips about choosing a contractor are available under “Save with 5” on our Web site or by calling the NorthWestern Energy Efficiency program phone line at (800) 823-5995.

NorthWestern Energy Encourages Montana Customers to Prepare for Major Winter Storm

web@northwestern.com — Fri, 22 Jan 2010 14:29:18 GMT

Butte, Mont. – January 22, 2010 – NorthWestern Energy is encouraging customers to be prepared for a significant ice storm event that is predicted to impact much of Montana this weekend.

Outages may result due to forecasted icing conditions in some locations in eastern Montana as well as high winds and heavy snow in some locations. NorthWestern Energy crews are on stand-by and will respond to outages when they are reported and when it is safe to do so. However, depending on the severity of the storm, driving conditions, and safety considerations, extended outages lasting longer than 2 hours are possible.

Customers are encouraged to be prepared for the possibility of extended outages, particularly those that live in rural areas where forecasted conditions are expected to be severe. Customers calling to report outages may experience extended on-hold times in the event of a large-scale outage situation.

Customers are reminded to use caution and common sense around electric power lines that are sagging or downed. Never attempt to touch or move a low-hanging wire as lines may still be energized even if they are lying on the ground.

Here are a few reminders in case electric service to your home or business is interrupted:

Contact NorthWestern Energy at 888-467-2669 to report outages, downed or sagging power lines. If you see fallen or sagging electrical wires, assume that they are “live,” and stay clear of the lines. Keep others away from wires and any other structures that may be energized. Call your local utility or local emergency services to report a downed or sagging power line.
Use portable generators only if a licensed electrical contractor in accordance with all federal and state codes and local ordinances has properly installed them. Portable generators should not be connected directly to your house or any building wiring. Doing so may feed power back on to our electric lines and threaten the safety of our employees working to restore an outage.

NorthWestern Energy Encourages Customers to be Prepared for Ice Storm Predicted to Affect Service Territory Over Weekend

web@northwestern.com — Fri, 22 Jan 2010 07:34:37 GMT

Huron, S.D. – January 22, 2010 – NorthWestern Energy is encouraging customers to be prepared for a significant ice storm event that is predicted to impact eastern South Dakota beginning Friday, and lasting through Sunday evening.

“Everything that has been forecasted about this storm is a bad recipe for electric utilities in the target area,” said Mike Sydow – South Dakota and Nebraska General Manager of Operations. “With the expected winds and icing happening at the same time, the area could be a mess by Saturday night. We have our emergency plans in place, and our entire staff is ready to react, should the need arise.”

NorthWestern Energy officials also warn customers to use caution and common sense around electric power lines that are sagging or downed. Never attempt to touch or move a low-hanging wire, even if you are positive that it is not a power line. Lines may still be energized even if they are lying on the ground.

Here are a few reminders in case electric service to your home or business is interrupted:

Contact NorthWestern Energy at (800) 245-6977 to report outages, downed or sagging power lines. If you see fallen or sagging electrical wires, assume that they are “live” and stay clear of the lines. Keep others away from wires and any other structures that may be energized. Call your local utility or local emergency services to report a downed or sagging power line.
Use portable generators only if a licensed electrical contractor in accordance with all federal and state codes and local ordinances has properly installed them. Portable generators should not be connected directly to your house or any building wiring. Doing so may feed power back on to our electric lines and threaten the safety of our employees working to restore an outage.
Beware of fallen or broken branches and trees as they are a major cause of power outages and could be energized if they are in or come in contact with a live electric line.
Keep an emergency kit ready—include flashlights, battery powered radio, canned foods that require no cooking, and fresh batteries. Some other things to be remember—only non-electric land line phones work during storm events when power is interrupted, and keep your cell phone fully-charged when storm events are forecasted. Also some cell phone towers do not work at full power after losing an electric feed.
Shut off appliances and lights, and unplug sensitive electronic equipment. Using a surge protector also helps to protect sensitive electronic equipment such as televisions and computers.

New Transmission Development Benefits Montana’s Economy

web@northwestern.com — Wed, 13 Jan 2010 12:49:14 GMT

Editor's Note: The following comments are provided by Dave Gates, Vice President, Wholesale Operations in response to Commissioner Brad Molner's opposition to building new electric transmission in Montana, which Mr. Molner has expressed in local papers.

One of the most exciting parts of this region’s economy is the development of “clean and green” energy resources, including the wind farms that are already producing power or are planned. They’re providing investment, revenue for landowners, jobs, and tax payments to support schools and essential public services. The energy sector has helped buffer Montana from the national recession. This very positive development depends on the construction of new transmission.

Public Service Commissioner Brad Molnar (who represents Billings and Southeast Montana) has recently expressed in local papers his strong opposition to building new electric transmission in Montana. As a utility regulated by Commissioner Molnar and the PSC, NorthWestern is very reluctant to exacerbate his increasingly negative view of the company, as well as of nearly any and all new transmission development in Montana. However, we must address the many errors throughout his column.

NWE is actively engaged in new transmission development that is necessary to enable new renewable energy development in Montana, particularly in central and north-central Montana where the wind resources are plentiful. We are working on three projects that could increase transmission export capacity by approximately 2,000 MW. A good summary of all of the proposed projects can be found on the Montana Department of Economic Development’s web site: http://commerce.mt.gov/energy.

NorthWestern’s customers are currently exposed to regional market-based prices. They have been ever since supply deregulation and MPC’s sale of the dams and thermal plants to PPL. Those regional market prices are directly tied to the California and western markets. This is neither a new or future phenomenon related to new transmission development as suggested by Commissioner Molnar; it is today’s reality. The best way to reduce this market exposure is for the utility to own its own generation dedicated to serve retail customers. That’s just what we’re doing. We are rebuilding a supply of cost-based, “rate-regulated” electricity to protect our customers from the fluctuations of regional market prices.

We have proposed these new transmission lines because of the requests we have received from electric generators wanting to connect to the regional grid. These requests are made through a federally regulated process that requires the company to provide non-discriminatory access to its system. Because these interconnection requests exceed the capacity on the existing system, federal regulations also require the company to accommodate these requests through appropriate expansion efforts to enable new customers and generators access to the system.

Of the 4,800 megawatts of new generation now waiting to access the system, approximately 3,000 is wind generation and the rest is natural gas, hydro, and miscellaneous, but includes no coal. True, any entity can ship power on our lines – we can’t discriminate – but there’s no need to build new transmission for existing power generation because it’s already being shipped through the system today. New transmission is needed for new generators, and the demand in the western United States is overwhelmingly for wind to help meet state renewable requirements.

The cost of these new transmission lines will be recovered from the energy developers, under long-term contracts, who actually use and benefit from the lines. That point was clearly outlined in our filings at the Federal Energy Regulatory Commission (FERC). Commissioner Molnar has been seeking assistance from county commissions to write letters to FERC asking the agency to support efforts to protect Montana consumers. We agree with Commissioner Molnar about protecting retail customers, and we are working with FERC to make sure that the necessary protections are in place. However, the letters that Commissioner Molnar has requested are in connection with a case that the FERC closed months ago.

As to the representations he made as to who has signed up we are bound by confidentiality and not at liberty to disclose who currently has reservations on MSTI and there are no public documents that name the entities. We can say that the reservations are held by other utilities, generators and marketers. We will be updating the reservation process in early 2010.

The numbers in the Commissioner’s article are inaccurate. Montana currently has approximately 6,000 MW of installed generation not the 1,900 that he quoted. NWE’s retail customers’ peak demand is roughly 1,200 MW, not the 1,850 MW cited. In fact, NorthWestern’s retail customers’ usage would equal only 20% of the energy generated in the state, if it all came from in-state, which it does not. NorthWestern operates a “Balancing Area” in Montana and provides services to other customers (cooperatives, industrial customers, other utilities, etc) and that number is approximately 1,900 MW.

Finally, Commissioner Molnar incorrectly claims that we have asked the government to pay for MSTI with a billion dollar stimulus grant. We have not made any such request, nor would we. MSTI is a billion dollar project that will be financed with 50-percent debt (borrowed) and 50-percent equity (cash). In the event government financing became an option, and assuming it is the least cost approach when the time comes, we will take look at it to lower the overall cost of the project – but that would be a loan to be paid back with interest.

New transmission projects will enable development of Montana’s great renewable resources. This will be good for local economies across Montana. These new energy sources need a pathway to market, which is the key reason to construct new transmission.

A Video Safety Message About Clearing Snow from Around Your Natural Gas Meter

web@northwestern.com — Mon, 28 Dec 2009 16:43:59 GMT

NorthWestern Energy Reminds Business and Residential Customers to Remove Snow and Ice from Natural Gas Meters and All External Exhaust Venting

web@northwestern.com — Mon, 28 Dec 2009 10:47:59 GMT

Huron, S.D. – December 28, 2009 – With the extreme amount of snow and drifting snow NorthWestern Energy customers received over the last 4 days, company officials are issuing an urgent safety message regarding snow and ice build up on, and around, natural gas meters.

Residential and business property customers who use natural gas, or who have natural gas or other fuel burning appliances, should take extra precautions to ensure their exhaust vents are cleared from snow build up, ice and drifting snow. Blocked appliance vents could result in a loss of heat or buildup of deadly carbon monoxide in the structure.

Customers are also strongly encouraged to carefully clear the snow away from natural gas meters. This will help prevent your natural gas regulator from freezing over, which would interrupt the normal flow of natural gas into your home. It will also give crews access to the meter in case an emergency shut off is needed, and will ensure meter readers can obtain accurate monthly reads.

“I can’t stress enough how important it is to keep exhaust vents and natural gas meters clear of snow, ice or other obstructions,” said Mike Sydow – General Manager South Dakota – Nebraska Retail Operations. “Businesses and residential natural gas meters require open air in order to work properly and safely, so while you clear snow from your property also remember to carefully clean snow and ice from your natural gas meter, and inspect all of exhaust vents to ensure they are working properly.”

Customers who use a contracted snow removal service are reminded to check their natural gas meters, as most snow removal services do not include this type of detail. Customers are also strongly urged to check all external venting to ensure snow and ice is clear and vents are working properly.

Commercial snow removal crews are also encouraged to use extra caution while clearing snow around natural gas risers, meters and all other utility facilities. Crews are also asked to not pile snow on top of or around pad mount transformers or switchgears.

NorthWestern Energy also strongly encourages customers to install UL-Listed Carbon Monoxide Detectors on each level of homes and businesses.

Customers with questions may call the Contact Center at (800) 245-6977.

NorthWestern Energy Reminds Customers to Remove Snow and Ice from Meters and Exhaust Vents

web@northwestern.com — Wed, 23 Dec 2009 11:45:55 GMT

Huron, S.D. – December 23, 2009 – NorthWestern Energy customers who heat their homes with natural gas or who have natural gas or other fuel burning appliances should make sure their exhaust vents are cleared from blowing and drifting snow. Blocked appliance vents could result in a loss of heat or buildup of deadly carbon monoxide in the structure.

Customers are also strongly encouraged to clear the snow away from natural gas meters. This will help prevent your natural gas regulator from freezing over, which would interrupt the normal flow of natural gas into your home. It will also make it easier for our employees to read your meter or shut off your natural gas service in case of an emergency.

“Keeping exhaust vents and natural gas meters clear of snow, ice or other obstructions helps keep your family safe and warm,” said Mike Sydow – General Manager South Dakota – Nebraska Retail Operations. “A good rule of thumb is whenever you scoop your sidewalks and driveway, also clear the snow away from the area around your natural gas meter, and inspect all of exhaust vents to ensure they are working properly.”

With blizzard conditions forecasted into the weekend, customers are urged to check heating vents, and also to clear snow and ice away from natural meters.

NorthWestern Energy also strongly encourages customers to install UL-Listed Carbon Monoxide Detectors on each level of homes and businesses.

Customers with questions may call the Contact Center at (800) 245-6977.

Helena Family Celebrating Energy Efficiency Thanks to Home Energy Makeover

web@northwestern.com — Tue, 22 Dec 2009 11:10:52 GMT

Butte, Mont. – December 22, 2009 – The Grotbo family of Helena will be enjoying the holidays in warmth and comfort all while saving energy thanks to their grand-prize winning entry in NorthWestern Energy’s Home Energy Makeover Contest.

The Grotbos entered the contest during the company’s fall Home Energy Expo events held around the state where CFLs and air-sealing measures were provided for free to qualifying customers. The contest was one of several activities to help encourage customers to learn more about the variety of energy efficiency opportunities available in the home.

Energy auditors have already gone through the family home to conduct a thorough diagnosis of the energy usage and installed appropriate air sealing measures where needed. NorthWestern Energy’s preferred contractors have installed energy efficient heating equipment and duct work and an ENERGY STAR qualified water heater. Increased insulation in the attic and in the basement walls is also part of the prize package. The home’s lighting fixtures have had CFLs installed where appropriate and water savings measure have been installed including faucet aerators and low-flow showerheads. The family also received a new ENERGYSTAR qualified home computer so that family members can continue to learn more about how to save energy using NorthWestern’s suite of online tools including Calc-U-Pal.

“We cannot believe that we won something this amazing! My mom and I almost didn’t fill out the entry forms because there were so many people in line, but at the last minute she said ‘Oh, let’s just throw them in,” said Janae Grotbo. “The best part about this is that our house needed all of this stuff! It’s funny how priorities change in life…we were so excited to win a furnace, water heater and insulation. Our family truly appreciates this amazing gift! Thank you NorthWestern Energy!”

“This grand prize awarded the Grotbos includes the installation of measures that typically provide customers the biggest energy savings for the investment. While not glamorous, low-cost measures such as air-sealing and CFLs, and insulation or larger ticket items such as the heating system and water heater deliver energy savings day in and day out,” said Bill Thomas, Manager – Regulatory Programs. “We offer rebates for customers to make cost effective efficiency improvements. We also encourage customers to look for the ENERGY STAR label when buying computers and other electronics because it helps consumers choose products that make a difference on their utility bill over the long run.”

NorthWestern Energy Seeks Additional Renewable Energy Supply in South Dakota

web@northwestern.com — Wed, 16 Dec 2009 10:38:13 GMT

Huron, South Dakota – December 16, 2009 – NorthWestern Corporation d/b/a NorthWestern Energy (NYSE:NWE) recently began delivering locally produced wind power to its South Dakota customers and is now seeking information about new renewable energy projects to add to its growing resource portfolio.

The company has issued a Request for Information (RFI) to owners or developers of potential energy projects in the amount of up to 25 megawatts. Responses are due by mid-January.

“We’re looking for cost-effective renewable energy projects to help us meet increasing customer demand that also allows us to further diversify our resource portfolio given the uncertainty associated with climate change legislation,” said Bob Rowe, President and CEO.

The RFI is open to all state-qualified renewable energy resources including wind, solar, biomass, hydro, geothermal and new waste heat projects. South Dakota has a voluntary standard that encourages utilities to provide 10-percent of their retail electricity from renewable energy sources by 2015. NorthWestern Energy’s recently completed purchase agreement with the Titan 1 Wind Project has helped it move closer to this goal.

While the company prefers to purchase the projects outright, it will consider other options to include equity interests in larger projects and long-term power purchase agreements. It will only consider projects that deliver both renewable energy and the associated renewable energy credits.

The RFI is available on the company’s Web site as well as that of its consultant Lands Energy Consulting. Responses to the RFI are due by January 18.

Any inquiries or correspondence regarding this RFI should be directed to Lands Energy Consulting:

Cold Snap Results in High Energy Use in Montana

web@northwestern.com — Wed, 09 Dec 2009 14:35:14 GMT

NorthWestern Energy Reminds Customers to Exercise Good Judgment to Stay Safe and Warm

Butte, Mont. – Dec. 9, 2009 – Heating systems are working overtime to keep up with record cold temperatures that continue to linger. NorthWestern Energy’s natural gas transmission system delivered a new post-Anaconda Company record of 299,290 dekatherms yesterday – the coldest so-far of the multi-day arctic freeze. NorthWestern’s electric transmission system control area load recorded a peak of 1,766 megawatts at 7 p.m. yesterday, which is still short of 2008’s peak of 1,805.

“This extremely cold weather will result in higher bills for customers because their heating appliances are working harder to keep their homes at a consistent temperature,” said Bobbi Schroeppel, vice president – customer care. “While we hope customers have taken our advice to weatherize their homes in advance of this weather – our primary concern at this point is that they remember that their family’s safety is more important than the amount of their bill. If anyone has concerns about anticipated higher bills as a result of this cold snap, it’s best to call us now so that we can help develop a plan to help customers manage their accounts.”

NorthWestern Energy reminds customers to keep their homes warm enough to prevent water pipes from freezing and to protect the health and safety of family members – particularly the very young and old. Under normal weather conditions the company suggests setting your thermostat no lower than 55 degrees at night and the setting that is most comfortable while the home is occupied during the day – typically around 67 degrees. However, during extreme weather events not all heating appliances are able to catch up with the heat loss with that range of setting. Depending on your situation, a temperature range greater than five degrees may result in your heating appliance working harder to catch up and may not result in significant energy savings.

The use of space heaters and wood stoves is also a concern during extreme weather events. Customers should make sure that any and all electric space heaters are used in accordance with manufacturer directions and that they are kept free of any potentially flammable material. Fuel burning space heaters and wood stoves should be properly vented to protect against the build-up of carbon monoxide.

Carbon monoxide build-up can result if fuel-burning appliances such as water heaters and heating system don’t have adequate air combustion or if vents, flues or heat exchangers become clogged, damaged or cracked. Carbon monoxide is a deadly poison that has no odor or taste, so the use of a good-quality CO detector and/or knowing the symptoms of CO poisoning is essential.

Here are a few safety tips to keep in mind and remember, if you have reason to suspect CO poisoning seek fresh air immediately and call NorthWestern Energy (1-888-467-2427) or 911 to check it out. It’s a free service regardless of the time.

CO Symptoms:

Symptoms are often described as flu-like and may include headache, fatigue, nausea, vomiting, confusion, tightening of the chest, unusual yawning and irritation of the nose and eyes.
Mild symptoms may alleviate when you leave the home and only to return when you return home.
If you have reason to suspect CO poisoning, call NorthWestern or 911 immediately and seek fresh air.

Keeping warm:

Use space heaters and wood stoves according to manufacturer directions and specifications.
Keep all fuel burning appliances well vented to the outside and free of any obstruction that may result in back drafting.
Never use any unvented fuel burning appliance including charcoal grills or space heaters indoors.
Use extreme caution with any open flames including candles or lanterns to prevent fires.

BP Wind Energy and NorthWestern Energy Announce Commercial Operation of the First Wind Facility in Hand County, South Dakota

web@northwestern.com — Thu, 03 Dec 2009 09:57:17 GMT

Project delivered ahead of expected 2010 schedule

BP Wind Energy and NorthWestern Energy today announced full commercial operation of the Titan I Wind Farm in Hand County, South Dakota, less than six months after the project started construction. Located on a 7500-acre site south of the town of Ree Heights, phase one of the wind farm will generate approximately one hundred million kilowatt hours of clean, renewable electricity every year for South Dakotans.

The Titan I Wind Farm is 100% owned and operated by BP Wind Energy, with the power produced sold to NorthWestern Energy for use by its customers in the state. Built by Mortenson Construction, the wind farm utilizes 10 Clipper C89 wind turbines each with a rated capacity of 2.5 megawatts (MW). A total of 175 workers were employed during peak construction of the first phase of the facility and a full-time staff of 6 is employed to monitor and maintain phase one.

“Today is a great achievement for a team of dedicated professionals in delivering full commercial operation of the Titan I Wind Farm,” said John Graham, president, BP Wind Energy. “It has been great to work with such a progressive thinking utility as NorthWestern Energy, and we look forward to exploring future opportunities of working together. Large wind farms such as Titan are the long-term future of the wind energy business. But, if this site is to reach its full potential of over 5,000 MW, then we are going to have to address the transmission challenges in order to build out what could be the largest wind facility in the world. All of us who are interested stakeholders in seeing this site expanded must work together to find the creative solutions we need.”

“Titan I will allow us to meet five percent of our South Dakota load with homegrown wind energy. We expect to add additional renewables to our resource mix in the next several years, and are well on our way to meeting the South Dakota Renewable Energy Objective of ten percent by 2015,” said Bob Rowe, President and CEO, NorthWestern Energy.

The first phase of the wind farm will tie into an existing above-ground 69 kV NorthWestern Energy transmission line.

About BP Wind Energy/BP America:
BP Wind Energy is a wholly owned subsidiary of BP, one of the world’s leading energy companies. In addition to the Titan I Wind Farm, BP Wind Energy has interests in a further six operating wind farms - Cedar Creek I, CO, Edom Hills, CA, Flat Ridge I, KS, Fowler Ridge I, IN, Silver Star I and Sherbino I, TX.

DOE Selects Pacific Northwest Regional Smart Grid Demonstration Project

web@northwestern.com — Tue, 24 Nov 2009 15:06:42 GMT

Regional project includes two NorthWestern Energy demonstration projects

Butte, Mont./Richland, Wash. – November 24, 2009 – The Department of Energy (DOE) has selected a Pacific Northwest team including NorthWestern Energy to conduct a regional smart grid demonstration project designed to expand upon existing electric infrastructure and test new smart grid technology with up to 60,000 customers in five states.

The Pacific Northwest Smart Grid Demonstration Project was one of 16 announced by DOE today. The team combines energy providers, utilities, vendors and research organizations. Total estimated cost for the project is $178 million. DOE will provide half the funding through the American Recovery and Reinvestment Act. The project’s participants, primarily utilities and industry partners including NorthWestern Energy, will provide the remaining funds.

NorthWestern Energy is one of two Montana utilities participating in the project. NorthWestern plans to test the operational efficiencies and customer service enhancements that may be gained by the installation of technology to enhance communication between the utility and the meter. The company plans to test this equipment on two circuits – an urban one in Helena and a rural one in the Georgetown Lake area. NorthWestern’s total project cost is expected to cost up to approximately $4.2 million of which half will be funded by the grant.

“We’re excited that our project will be moving forward in coordination with the other members of the team,” said Bob Rowe, NorthWestern Energy’s President and CEO. “Participating in this regional effort will allow us to share information and lessons learned to determine how best to move forward with cost-effective deployment of a broad range of smart grid technologies. This is particularly critical from our perspective as one of the most rural investor-owned utilities in the country. The project also complements our focus on enhancing distribution system infrastructure.”

Smart grid technology includes everything from interactive appliances in homes to substation automation and sensors on transmission lines. It is a system that uses various technologies to improve power delivery and use through intelligent, two-way communication. Generators of electricity, suppliers and users are all part of the equation. With increased communication and information, smart grid technology enables real-time monitoring of electric energy consumption, exchange of data about supply and demand, and adjustments of power consumption when the grid is under stress to ensure consistent delivery of electricity.

DOE will provide half the funding through the American Recovery and Reinvestment Act. The project’s participants, primarily utilities and technology companies, will provide the remaining funds.

Several technology companies and vendors also will support the project including: 3TIER Inc., AREVA USA, IBM, Netezza Corp., and a team of QualityLogic, Inc. and the Drummond Group, Inc.

The project team will install equipment and technology in 2010 and 2011. Then, for the next two to three years, project leaders will gather data on smart grid performance from 15 test sites that represent the region’s diverse terrain, weather and demographics. The test sites range from Fox Island in Washington State’s Puget Sound, to the Teton Mountains in western Wyoming, and includes the campuses at the University of Washington and Washington State University.

The project will involve more than 112 megawatts of power, enough to serve 86,000 households.

MPSC Accepts Motion for Reconsideration Regarding Recent General Rate Filing

web@northwestern.com — Tue, 24 Nov 2009 14:49:39 GMT

Butte, Mont. – Nov. 24, 2009 – NorthWestern Energy (NYSE:NWE) announced today that the Montana Public Service Commission (MPSC) has accepted its motion for reconsideration regarding the MPSC’s Nov. 12, 2009, decision that the company’s general rate filing did not meet the MPSC’s applicable minimum filing requirements, primarily related to allocated cost of service and rate design.

As a result of today’s hearing, NorthWestern does not need to re-file its general rate case and will work with MPSC staff to determine what additional information is necessary to meet the MPSC’s minimum filing requirements and submit a supplemental filing by January 15, 2010. The MPSC indicated that it will decide by the end of January whether the supplemental filing meets the MPSC’s minimum filing requirements.

Assuming the supplemental filing is found to meet minimal filing requirements, NorthWestern agreed to extend the timeframe by which the MPSC must issue a final order concerning the general rate filing by 90 days to October 11, 2010.

NorthWestern is pleased with the MPSC’s decision and the opportunity to work directly with MPSC staff to address the submittal of supplemental information.

In its Oct. 16, 2009 rate case filing, NorthWestern proposed a revenue requirement increase of approximately $1.96 million for its natural gas utility and approximately $15.5 million for its electric utility.

NorthWestern Energy and NEEA Offer Energy Efficient Suggestions for Electronics Shoppers this Holiday Season

web@northwestern.com — Tue, 24 Nov 2009 07:23:43 GMT

Butte, Mont. – November 24, 2009 – As shoppers peruse the sale ads for Black Friday deals on big screen televisions, NorthWestern Energy and the Northwest Energy Efficiency Alliance (NEEA) are joining forces this holiday season to promote top-of-the-line televisions that are especially energy efficient.

The super-efficient televisions are all at least 30 percent more energy efficient than current ENERGY STAR® specifications require. NEEA and NorthWestern Energy are promoting the TVs as part of a consumer electronics program designed to reduce household power use.

“The advanced technology found in the super energy-efficient TVs in many cases can improve the television performance and picture quality,” said Deb Young, an energy efficiency program manager at NorthWestern Energy. “So now, consumers will see how high-performance technology maximizes home energy efficiency – translating into monthly utility bill savings and a smaller environmental footprint,” she added.

Shoppers can identify the super-efficient televisions this holiday season by a green SAVE MORE label. The labels also will include the ENERGY STAR and NorthWestern Energy’s logo.

Participating retailers include Wal-Mart, Best Buy, Costco, Sears, Sam’s Club, Kmart, and Vann’s. Other independent community retailers also will soon begin to participate in the energy-efficient electronics program.

The NEEA and NorthWestern Energy program comes as people are increasingly concerned about the energy their home electronics consume.

Television use in the Northwest consumes nearly 3.7 billion kilowatt hours of energy each year, according to estimates from the Northwest Power and Conservation Council.

According to the International Energy Agency, consumer electronics represent 15 percent of worldwide home power demand – a percentage expected to triple over the next 20 years.

And the International Energy Agency reported that consumer electronics represent the fastest growing category of household power demand in the world. That is reflected in Northwest power consumption patterns as well.

Customers say their concerns about this energy consumption – concerns for the planet and for their wallets – will influence their future television purchases.

A 2008 Consumer Electronics Association survey found that 89 percent of households wanted their next television to be more energy-efficient.

And super-efficient televisions could make a big difference in the Northwest, say NorthWestern Energy and NEEA officials.

“Here in the Northwest, there are now more televisions per home than people. This, combined with the fact that technology is available to reduce their electricity consumption by 30 to 50 percent, makes efficiency improvements in televisions among the largest single sources of conservation potential in the region,” says Tom Eckman, Resource Conservation Manager, NW Power and Conservation Council.

All televisions promoted through the super-efficient television program must be at least 30 percent more energy-efficient than current ENERGY STAR® specifications. ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy helping consumers save money and protect the environment through energy- efficient products and practices.

Televisions that qualify for the SAVE MORE labeling are those on the Consortium for Energy Efficiency’s Tier 3 and Tier 4 list of televisions. That list is available at http://www.northwesternenergy.com/ or http://www.cee1.org/files/TVQualifyingProductList.pdf.

For more information about the consumer electronics program and products, please visit: http://www.energyefficientelectronics.org/.

About the Northwest Energy Efficiency Alliance
The Northwest Energy Efficiency Alliance (NEEA) is a private non-profit organization funded by Northwest utilities, the Energy Trust of Oregon and the Bonneville Power Administration. NEEA works in collaboration with its stakeholders and strategic market partners to accelerate the sustained market adoption of energy-efficient products, technologies and practices. NEEA’s market transformation efforts address energy efficiency in homes, businesses and industry. For more information about NEEA, please visit: http://www.nwalliance.org/.

MPSC Rules NorthWestern Energy May Re-file General Rate Filing to Comply With State Minimum Filing Requirements

web@northwestern.com — Thu, 19 Nov 2009 04:01:00 GMT

Butte, Mont. – Nov. 19, 2009 – NorthWestern Energy (NYSE:NWE) announced today that the Montana Public Service Commission (MPSC) recently determined that the Company’s general rate case filing on Oct. 16, 2009, did not meet the MPSC’s applicable minimum filing requirements, primarily related to allocated cost of service and rate design.

In its rate case filing, NorthWestern proposed a revenue requirement increase of approximately $1.96 million for its natural gas utility and approximately $15.5 million for its electric utility.

NorthWestern’s proposed filing also included new cost allocation between rate classes and rate designs. The proposals introduced an inclining block residential rate structure that would assign more costs to residential customers that use more energy within each rate class. Under this methodology, some customers would see higher increases than the average residential customer while other residential customers may experience lower than average rates.

In response to the MPSC’s action, NorthWestern submitted a motion for reconsideration or in the alternative, if it is denied, a motion to bifurcate the general rate case into a revenue requirement proceeding and an allocated cost of service and rate design proceeding. The Company believes the motion to reconsider bears merit because the filing does, in fact, comply with the MPSC’s filing requirements. In addition, should the MPSC deny the motion for reconsideration, the motion to bifurcate would allow a separation of the overall revenue requirement from the allocated cost of service and rate design rules, allowing a proceeding on the revenue requirement to continue.

NorthWestern expects the MPSC to rule as early as next week on the motions. If the MPSC’s initial determination stands, the Company expects to correct the deficiencies and re-file the rate case. If a re-filing is required, the rate case decision likely would be delayed from the third quarter of 2010, as previously anticipated, to the fourth quarter of 2010.

NorthWestern Energy Submits Delivery Services General Rate Case Filing to the Montana Public Service Commission

web@northwestern.com — Mon, 19 Oct 2009 04:05:00 GMT

Butte, Mont. – October 19, 2009 – NorthWestern Energy (NYSE:NWE) today submitted its general rate filing to the Montana Public Service Commission seeking approval to change several components of its delivery services charges for Montana electricity and natural gas customers. This filing was required pursuant to a stipulation approved by the Montana PSC in 2008.

If approved, the proposed changes would result in an increase of $0.08, or less than one-tenth of one percent, for a typical natural gas customer using 10 dekatherms/per month. A typical residential electric customer’s total monthly bill would increase by $2.41 or about 3.35%. The company has asked for an interim rate adjustment pending the full review by the Commission.

“This filing addresses the foundational aspects associated with the day-to-day operations and maintenance of our electric and natural gas infrastructure,” said Bob Rowe, President and CEO. “Despite the economic downturn and other challenges, this is an exciting time to work at NorthWestern. We’re making the appropriate investments in our system to provide safe and reliable service. We’re engaging our stakeholders at all levels to prepare our system to meet the expectations our customers have for utility service now and in the future.”

The proposed changes include new cost allocation between rate classes and rate designs. The proposals introduce an inclining block residential rate structure that would assign more costs to residential customers that use more energy within each rate class. Under this methodology, some customers would see higher increases than the typical residential customer while other residential customers may experience lower rates than average. The intent of the inclining structure is to provide additional incentive to larger volume residential users to reduce their consumption through adoption of energy efficiency measures.

The amount of the proposed rate increases, based on a requested authorized return on equity of 10.9% and a weighted cost of capital of 8.3%, has been reduced as a result of a reduction to income tax expense due to recent changes made to the tax accounting method related to capital expenditures and repair expenses. As a result of this change, NorthWestern’s proposed revenue requirement for its natural gas utility was reduced from approximately $4.8 million to $1.96 million and for its electric utility from $24.1 million to $15.5 million. The general rate filing does not address energy supply issues, which are addressed in other proceedings. The transmission and distribution components of a typical total bill represent less than 50% for residential electric and natural gas customers with energy supply costs making up the balance of the bill amounts.

The charts below show the relationship between the regulated delivery service costs and rates and “pass through” electric and natural gas supply costs. Delivery rates have been stable in recent years with relatively few and relatively modest adjustments. Volatility in customer bills has been primarily due to adjustments in market-based natural gas and electric supply costs, which commonly comprise more than one-half of a customer’s total bill.

Innovative Partnership to Develop Community Based Biomass Power in Montana

web@northwestern.com — Thu, 15 Oct 2009 11:32:33 GMT

NorthWestern Energy and Montana Community Development Corporation are partnering with sawmills and landowners

Butte/Missoula, Mont. – October 15, 2009 – NorthWestern Energy and the Montana Community Development Corporation (MCDC) are partnering with eight Montana sawmills and public and private landowners to help develop community-based biomass power in Montana. The partnership will create a coordinated business plan to enable the production of wood-fueled power in the state.

The joint effort includes every player in the chain of biomass power production including owners of existing forest products facilities, public and private landowners and a regional power purchaser. “Bringing all the essential players to the table is what makes this partnership so unique,” says Rosalie Cates, President of MCDC.

Individual sawmills have previously worked on separate plans to produce and provide NorthWestern Energy with biomass generated power by constructing wood-fired plants at various locations in the state. However, each mill encountered significant cost and technical issues when it came to delivering the power to the grid.

NorthWestern wants to help bridge that gap. “We know that biomass power can be good for forests, and good for Montana’s timber industry,” said John Fitzpatrick, NorthWestern’s Executive Director – Government Affairs. “This feasibility study will lead to the development of a comprehensive business plan that addresses our goal of adding a significant amount of biomass resources to our portfolio.”

“If this project moves forward it will help address the environmental impact of pine beetle blight, provide a local economic development impact, and help diversify electric supply for our customers. We have discussed with our Congressional Delegation ways that federal energy and climate legislation could help support this exciting project,” said Bob Rowe, NorthWestern Energy’s President and CEO.

The partnership’s feasibility study includes analysis of the biomass supplies available on private and public land, potential biomass generation facilities, operational requirements and preliminary impacts of the biomass production on local economies and the environment. Each of the eight mill sites will be assessed, so that NorthWestern and the sawmill businesses can identify and address issues such as connectivity to power lines, cost efficiencies, and technical problems. The end result of the process will be a statewide plan that could enable all parties to finalize investment plans and begin plant construction.

“It is not every day that this kind of joint effort comes together,” added Cates. “The issues around biomass sourcing, community-sized power facilities, and connection to transmission are very complex. Only in Montana do small power producers like these sawmills have the opportunity to work directly with the power company to find solutions. I think it will be a model nationally. ”

The participating mills are Eagle Stud Mill (Hall), Plum Creek Timber (Columbia Falls), RY Timber (Townsend and Livingston), Pyramid Mountain Lumber (Seeley Lake), Sun Mountain Lumber (Deer Lodge), Tricon Timber (St Regis), and FH Stoltze Land & Lumber (Columbia Falls)

All of the state’s major forestland owners are participating in the partnership including the: US Forest Service, Montana Department of Natural Resources and Conservation, Plum Creek Timber, The Nature Conservancy, Stimson Lumber Company and the Blackfoot Challenge.

The Biomass Energy Feasibility Study is partially funded by a grant from The Montana Department of Commerce in the amount of $125,000, authorized by The Montana Reinvestment Act. The US Endowment for Forestry and Communities provided a grant of $50,000 to support MCDC’s work with biomass energy in Montana. Carlton Owen, Endowment president and CEO, believes this partnership could be a national model for woody biomass power generation. “The $50,000 award to MCDC recognizes the relevance and importance this project holds for forests, wood products manufacturing and domestically- produced energy across the nation.”

NorthWestern Energy Submits Energy Efficiency Program Plans to South Dakota Public Utilities Commission For Consideration

web@northwestern.com — Fri, 09 Oct 2009 09:14:42 GMT

Huron, S.D. – October 9, 2009 – NorthWestern Energy has submitted a plan to the South Dakota Public Utilities Commission that, if approved, would enable the company to offer its customers a broad array of energy efficiency programs.

Demand Side Management (DSM) Programs are energy efficiency programs or plans that encourage customers to conserve energy through the installation of energy saving equipment, building upgrades, energy consumption habit modification, and overall energy usage education. The end result is educated consumers and less wasted consumption of energy.

An added benefit of DSM programs to energy customers, shareholders and utilities is that by using less energy, utilities are able to prolong their need for rate increases by delaying the need to construct expensive peak generation or base load generation projects.

NorthWestern’s Montana utility has offered successful DSM programs for approximately 20 years and the SD DSM Plan is based on the company’s experience with those programs. Under the submitted plan, SD DSM programs would be funded through a monthly per customer surcharge that mirrors similar funding mechanisms used by energy utilities in their SD PUC approved DSM plans.

“In talking with our customers over the past few years we have learned that many are very interested in learning about things they can do to their home or business to help conserve energy,” said Pamela Bonrud – Director SD/NE Government and Regulatory Affairs. “That desire to ‘do it yourself’ tells us that this is the right time for our South Dakota customers to receive benefits for that way of thinking.”

The proposed DSM Plan includes rebates for the installation of energy saving products, like insulation, lighting and programmable thermostats. Home and business energy audits will be a key component of the proposed DSM Plan should it receive PUC approval. Mail-in energy audits would be available to residential electric customers that use electricity for only lights and appliances. Electric and natural gas space heating and water heating customers would qualify for on-site home energy audits, if their home is more than five years old. Audited customers would receive feedback about their energy usage habits, and the recommended steps to resolve inefficient habits or structural deficiencies causing excessive energy consumption.

“The home energy audit is the cornerstone of our DSM plan, and it is one of the best things that customers could be involved with in order to improve their energy efficiency,” said Bobbi Schroeppel – Vice President Customer Care/Communications/Human Resources. “During our Home Suite Home Giveaway in 2008, a South Dakota family won a new energy efficient clothes washer and dryer. Also included in the prize package was an on-site home energy audit. The winning family said the most valuable item in the prize package was the information gleaned from the auditors.”

Assuming the SD PUC approves the program by the end of this year, the company intends to begin rolling out the programs to customers in early 2010.

NorthWestern Energy Issues Important Safety Reminders About Downed Power Lines and Other Weather-Related Concerns

web@northwestern.com — Mon, 05 Oct 2009 13:01:20 GMT

Butte , Mont. – October 5, 2009 – As the first major winter storm of the season pushes through Montana, NorthWestern Energy is reminding customers how to stay safe and warm during severe weather.

Downed power lines are potentially a problem in areas that experience high winds or heavy snow loading. Downed power lines may still be energized and should be avoided at all times. Stay away from downed or low hanging power lines (even if you think it may be a phone or cable line). Keep others clear of the area and call NorthWestern Energy or 911 and we will come take care of it as soon as possible.

If your home or business loses power, please call us to report the outage. Occasionally, outages during major storms may be longer than normal. While our crews will be working as quickly as possible to restore any electric outages that may occur, there are a few things in the event the electricity goes out.

Remember to keep freezer and refrigerator doors closed to retain the cold.
Unplug sensitive electrical equipment such as computers and televisions.
Keep flashlights (with fresh batteries) handy and easily accessible.
Keep portable generators in good working condition, and set up according to the manufacturer’s specifications by qualified electricians to ensure your safety and the safety of our employees who may be working to restore your service.

Natural gas customers should make sure their appliance vents are kept clear of snow and ice. Customers who are having problems with their heating units should check first to ensure the appliance vents are clear of snow, clean, and in good repair to ensure proper venting. Other safety tips to remember if you lose heat in your home:

Use a wood stove or fireplace only if they are in safe working condition and vented outside.
Only use propane or kerosene space heaters as a last resort, and be sure to leave a window open ensuring adequate ventilation to allow sufficient combustion air and to permit exhaust by-products to exit. Carbon monoxide (CO) can build up quickly if the heater isn't working properly.
Do not place a space heater within three feet of anything that may catch on fire, such as drapes, furniture, or bedding.
Never use a hibachi or charcoal barbeque indoors—the fumes are deadly.
Don’t try to heat your home with the flame from a range or oven.
Elderly people, infants, and people with certain medical conditions are at greater risk of hypothermia, even indoors. Dress in layers, and use blankets to ward off a chill. Drink warm beverages, but avoid alcohol and caffeine, which can exacerbate hypothermic situations. If you lose heat in your home, consider going to another location that has heat.

If you experience problems with natural gas heat or an electrical outage, please call
NorthWestern Energy right away.

NorthWestern Energy Provides Update on Upcoming Montana General Rate Case Filing

web@northwestern.com — Tue, 29 Sep 2009 15:40:52 GMT

Butte, Mont. – September 29, 2009 – NorthWestern Energy (NYSE:NWE) today filed a motion with the Montana Public Service Commission requesting permission to delay the filing of its anticipated general rate case up to one month while it reviews the implications of recently received Internal Revenue Service approval to change the tax accounting method related to capital expenditures and repair expenses.

NorthWestern was notified last Friday that the IRS had accepted a tax position advocated by NorthWestern to change the tax accounting method related to certain capital expenditures and repair expenses. Pursuant to that notification, NorthWestern has forty-five (45) days to formally accept the IRS notification. NorthWestern is currently reviewing the impact of this tax accounting change both internally and externally with its outside tax accounting firm, and anticipates that it will formally accept the IRS position.

Initial analysis of the impact of this tax accounting change reveals a potentially substantial material reduction to current income tax expense and a corresponding reduction to the revenue requirement NorthWestern will be proposing in its general rate case filing. Within the next few weeks, NorthWestern plans to incorporate the new tax accounting change into its general rate case application, re-work the statements, work-papers and testimony accordingly, and file the general rate case application as soon as possible, but by no later than October 30, 2009.

NorthWestern Energy's Montana Customers Invited to Do-It-Yourself Home Energy Expo and Events

web@northwestern.com — Mon, 21 Sep 2009 15:23:34 GMT

Butte , Mont. – September 21, 2009 – While electricity and natural gas costs are expected to remain fairly moderate this winter compared to previous years, the company strongly encourages customers to take the appropriate steps to keep their homes safe and warm beginning with a visit to a “Do-it-yourself Home Energy Makeover” expo or event this fall.

More than 40 events are planned in locations around Montana beginning this week and continuing through mid-November. The company will be distributing free weatherization kits to customers who have not yet received a kit in previous years. Customers who have previously received kits should still plan to attend a Home Energy Expo, which includes a variety of activities such as pictures with Louie and Sniffy, balloons and giveaways for the kids, free refreshments, safety education and E+ how-to demonstrations.

NorthWestern Energy expects electricity supply costs to be about the same as last year while natural gas costs are expected to be about 15-percent lower than last year. Actual bill amounts depend on how much energy a customer uses and so far the experts seem divided on whether this will be a mild or a colder than normal winter. That’s why NorthWestern emphasizes low-cost weatherization measures to help your home better withstand the elements – what ever they may be.

This year at the Saturday expos, the company also will distribute free carbon monoxide detectors to residential gas customers (limit one per household and while supplies last) and we’ve invited a variety of vendors to provide information, displays and demonstrations to compliment NorthWestern’s E+ rebate programs. The National Weather Service is hosting a booth this year and the Montana Department of Environmental Quality (DEQ) will provide information on state and federal tax incentives for implementing energy efficiency measures. In addition, NorthWestern Energy customers can register to win an extreme home energy makeover by registering for the Home Energy Makeover contest.

“Many of our customers are interested in learning how to be smart energy consumers, so we’ve expanded our events this year to include presentations on everything from our rebate and incentive programs to small scale renewable energy applications,” said Bobbi Schroeppel, Vice President – Customer Care and Communications. “Customers that are interested in finding ways to save energy will be able to speak one-on-one with energy experts.”

Residential electric customers who have not received free Compact Fluorescent Light (CFL) bulbs from NorthWestern at any other event this year are eligible to receive free CFL bulbs at the expos or weekday kit giveaway events. NorthWestern Energy natural gas home space or water heating customers who have not received a starter weatherization kit at any prior event or through a home energy audit may be eligible to receive a free weatherization kit at the expo or events. Further qualifications may apply.

MSTI Will Provide Economic and Environmental Benefits

web@northwestern.com — Tue, 01 Sep 2009 15:53:44 GMT

Editor's Note: The following comments are provided by Dave Gates, Vice President, Wholesale Operations in response to Commissioner Brad Molner's column which appeared in The Montana Standard on August 20, 2009.

Butte, Mont. — September 1, 2009 — A recent exchange on this page between Public Service Commissioner Brad Molnar and four legislators raised some questions about NorthWestern Energy’s Mountain States Transmission Intertie (MSTI) power line proposal.

Rather than rehash the arguments, let me restate the information needing clarification.

We, at NorthWestern Energy, are rebuilding a supply of cost-based “rate-based” electricity to protect our customers from the fluctuations of regional market prices.
Transmission projects such as MSTI will enable development of Montana’s great renewable resources. Clearly, this will be good for local economies across Montana and help to address environmental concerns including climate change. These new energy sources need a pathway to market, which is the key reason to construct MSTI.
The cost of building MSTI will be recovered from the electric customers who actually use and benefit from the line.
The process of selecting a final route for MSTI or any other transmission line is designed to take into account landowner, environmental, cultural, economic and other concerns. This process is ongoing.

The only way to fully insulate ourselves from the electricity market is to own our own rate-based energy supply. These are energy sources that are dedicated to our Montana customers at cost-of-service rates instead of market rates. NorthWestern’s customers have been tied to and exposed to those markets since Montana Power Company sold its rate-based coal plants and dams (over the objection of its employees), and customers began paying market prices.

Since the law authorizing NorthWestern Energy to once again rate base electricity supply passed in 2007, we’ve locked in about 25 percent of our supply into rate-base. We’re looking right now for cost-effective renewable projects as part of our ongoing effort to replace market-based contracts over time. We also are building Mill Creek Generation Station, which will provide critical “regulation” services (keeping the system in balance) for our customers, so that we won’t have to purchase these services on the market.

As a regional transmission operator, we are required by federal law to build transmission necessary to meet the demand. Currently, there are approximately 5,000 megawatts of new Montana energy sources that want access to our transmission system for the purpose of selling energy to customers. The demand for this energy is largely out-of-state. Most of the new proposed projects are renewable – wind and hydro – as that is the future of energy development. This creates an opportunity for “Made in Montana” environmentally-responsible clean, renewable resources to help energize the nation, just as farmers and ranchers grow crops and raise cattle to help feed the nation.

In addition to MSTI, our “Collector Project” is a set of up to five new 230 kV transmission lines (depending on need) that will connect these new Montana energy sources to the existing transmission system and then to MSTI. Assuming that they are all built, that will eventually add 2,000 MW of new capacity to the system, which is roughly equal to the expected combined capacity of the MSTI and the planned upgrade to the Colstrip Transmission System.

Because the existing transmission system already has more demand than available capacity, new transmission such as MSTI is necessary to relieve the bottleneck that exists on the southwestern end of our system. We have existing reservations of space on MSTI and will be conducting another Open Season that will update those reservations and add additional capacity reservations. To protect the competitive information of these shippers, FERC regulations require that the identities of participants remain confidential.

Documents we have submitted to FERC clearly show that MSTI is being built to serve new generation for export. These documents also clearly show that MSTI’s customers, who directly benefit from the line, rather than the existing customers of NorthWestern Energy will pay costs associated with MSTI.

We’re doing our part to meet the changing needs of our state, region and nation while at the same time protecting existing customers from potential unintended consequences. We remain committed to working with our regulators, customers, communities and responsible community organizations to find workable solutions that enable energy development with the least possible impact on people, animals, and living systems.

Dave Gates is NorthWestern Energy’s VP of Wholesale Operations including the company’s transmission operations headquartered in Butte. Gates lives south of Butte.

NorthWestern Energy Responds to Chronicle’s Opinion

web@northwestern.com — Tue, 01 Sep 2009 15:42:48 GMT

Butte, Mont. — September 1, 2009 — Last week, NorthWestern Energy held the most recent in a series of public meetings to brief the community on our Bozeman infrastructure investment project, progress in determining the cause of the March 5th explosion, and other matters. We did so to share the information we have with the Bozeman community, including the downtown community and others affected by the accident. We also meet regularly with smaller groups and with individuals in the Bozeman community.

We know that the time the investigation has taken has been frustrating for many, especially the victims. In the meantime, we have tried to be helpful, and to be responsible members of the Bozeman community. We have, for example, contributed $50,000 to the Downtown Relief Fund to help victims of the explosion and we made an additional $50,000 contribution to the city’s loan fund to assist the downtown businesses with the site cleanup. Although the clean-up funds weren’t tapped, our contribution will remain available for appropriate uses downtown.

Much of what we have done to date has been in response to suggestions made by the local community, which we sought out in the days immediately after the explosion. We accelerated our annual program of natural gas inspections and safety activity, compressing a yearly cycle into several months. We opened a Main Street office, communicated about safety, and supported a campaign to attract customers downtown. We’ve done what we can to make the process of filing claims as accessible as possible.

Most importantly, we have made a major capital commitment to accelerate our gas system maintenance program in downtown Bozeman to help the downtown area “get back to normal” quicker and avoid the further disruption that would have been caused by ongoing construction that was originally scheduled to take place over the next several years.

We have met with most of the affected property owners. We understand and appreciate their frustrations, particularly those who feel they are caught between a rock and a hard place. They have insurance, but may not have enough to cover all the costs of rebuilding, and they are dealing with a financial system that has tightened its lending practices in light of the recession and recent credit crisis.

We believe, however, that the perception that the affected businesses are “in limbo” because the various insurers are “staring each other down” may not be entirely correct. Most of the businesses that were damaged have insurance and those businesses’ insurers are adjusting their insured’s losses without awaiting the results of the investigation. After a slower start than others and we would have liked, the various parties’ insurers have worked well with each other to investigate the cause of the accident.

We understand but respectfully disagree with the Chronicle’s opinion that NorthWestern should step forward and advance funds before the cause of the explosion is pinpointed and before – or perhaps regardless of whether - any fault is ultimately determined. Our legal system has a method for assigning liability, based on a determination of whether negligence occurred or whether an event took place, for example, because of natural forces. That is what the insurance companies, lawyers and experts are working through.

Accordingly, we respectfully question whether it is fair to place the blame on NorthWestern at this time. As I stated at the briefing last week, I am not an expert in the subject of the investigation, and recognize that as the matter progresses others may communicate different assessments of the evidence than have our experts, different theories, or propose additional tests. As your editorial acknowledged, “there may never be a definitive explanation of what caused the blast.”

It is fair is to follow a careful path of investigation and provide information to the community, while doing our best to answer citizens’ questions. If there are lessons to be learned we will learn them and tell the community about them. If changes need to be made, they will be made and we will also tell the community about those.

NorthWestern Energy will continue to support the downtown Bozeman recovery effort in substantive ways. We must do so while balancing our responsibility to all of our customers for safe and reliable electric and natural gas infrastructure and energy supply. I have personally appreciated the Bozeman community’s willingness to discuss difficult matters frankly and constructively, and to work with us to help us be the best utility we can be for all of our customers.

NorthWestern Energy Seeks Additional Renewable Energy Supply in Montana

web@northwestern.com — Mon, 17 Aug 2009 13:46:06 GMT

Butte, Mont. – August 17, 2009 – NorthWestern Corporation d/b/a NorthWestern Energy (NYSE:NWE) already has one of the highest percentages of total renewable energy supply of any utility in the Northwest and it is now looking to add even more to its electric generation portfolio.

The company has issued a Request for Information (RFI) to owners or developers of potential projects that meet state standards for renewable energy and/or projects that meet the requirements for Community Renewable Energy Projects (CREP). The company is seeking to add 25-75 megawatts of renewable electric generation to its portfolio. Responses are due by the end of September.

“We’re looking for innovative, cost-effective renewable projects that we can add to our growing portfolio of rate-based electricity resources,” said Dave Gates, Vice President – Wholesale Operations. “In addition to further diversifying our portfolio, the addition of renewable resources favorably positions the utility given pending climate change legislation.”

According to John Hines, Chief Energy Supply Officer, the RFI is open to all qualified renewable energy resources ranging from wind and biomass to landfill gas and hydrogen and everything in between.

While the company prefers to purchase the projects outright, it will consider other options to include equity interests in larger projects and long-term power purchase agreements. It will only consider projects that deliver both renewable energy and the associated renewable energy credits.

The RFI is available on the company’s Web site www.northwestern.com/ as well as that of its consultant Lands Energy Consulting www.landsenergy.com/. Responses to the RFI are due by September 30. Any inquiries or correspondence regarding this RFI should be directed to Lands Energy Consulting:

NorthWestern Energy Adds Additional Route Options to Jack Rabbit-Big Sky Transmission Line

web@northwestern.com — Wed, 05 Aug 2009 14:41:01 GMT

Butte , Mont. – August 5, 2009 – In response to local residential concerns over a planned upgrade of its transmission line between the Jack Rabbit Substation near Four Corners and Big Sky, NorthWestern Energy is now evaluating alternative routes for the section of line that is currently located on Magenta Road.

While the Magenta Road portion is still under consideration, the company has added three potential alternative routes in the neighborhood located roughly south and west of Four Corners. The proposed route is unchanged along Highway 191 from South of Lower Rainbow Road to the Meadow Village Substation in Big Sky.

“Initial plans called for building the new line entirely parallel to the existing line which will be removed when the new line is placed into service, but we’re sensitive to concerns expressed by residents along Magenta Road about the size of the new line in comparison to their unusually narrow street,” said Dave Gates, Vice President of Wholesale Operations. “At the same time we recognize that moving the line to another location in the neighborhood poses concerns for newly affected residents, so we’ve amended and reposted the public notice to give them the opportunity to fully participate in the process.”

The existing line and the proposed alternative routes are primarily located on public rights-of way under the jurisdiction of Gallatin County. Maps that show details of the alternative routes under consideration are included with the public notice that appears in three local newspapers this week and they are posted on the company’s Web site (click here).

NorthWestern Energy plans to replace the existing 69 kV line with a 161 kV line to provide additional capacity and reliability to serve customers in southwest Montana. This is an area that has experienced significant growth in recent years and that growth is expected to continue over the next 20 years. NorthWestern typically provides at least two distinct and geographically separate routes for most of the communities it serves to provide continued reliability in the event one line is out of service or threatened by wildfire. This line and another line that comes in from the west serve Big Sky and the Gallatin Canyon.

The company plans to build the new line under a statutory exclusion from the Montana Major Facility Siting Act. Under Section 75-20-104(8)(a)(ii), MCA, the line would be excluded from Siting Act coverage if NorthWestern obtains right-of-way agreements or options for a right-of-way from more than 75 percent of the landowners who collectively own more than 75 percent of the property along which the new line is to be located.

If the company is unable to obtain the statutory exclusion, the Siting Act's full public and agency review provisions will apply to the new line. The Montana Department of Environmental Quality (DEQ), which administers the Siting Act, will then determine the line location.

Discussions with landowners along the new proposed routes cannot begin until 60 days following publication of the last public notice. The company is plans to host an Open House for residents later this fall to provide information about the project and how to participate in the process.

BP Wind Energy and NorthWestern Energy Welcome South Dakota Governor Rounds to First Wind Project in Hand County

web@northwestern.com — Wed, 05 Aug 2009 10:30:52 GMT

Project to be largest in world if built out to full capacity

Sioux Falls, S.D. – August 5, 2009 – BP Wind Energy and NorthWestern Energy (NYSE: NWE) today welcomed South Dakota Governor Michael Rounds at a wind turbine blade signing event to celebrate the move into full construction of the Titan I Wind Farm in Hand County, South Dakota.

Governor Rounds, who was joined by other state and local elected officials, landowners and community leaders said: “Today marks an important step in delivering clean power from a renewable resource, and that’s a credit to innovative thinking and planning by the partners in this project. South Dakota has tremendous potential to become a leader in wind energy development, and utilization of this abundant natural resource harbors the potential of great economic promise for the state.”

Located on a 7500-acre site south of the town of Ree Heights, the Titan I Wind Farm is 100% owned by BP Wind Energy with the energy sold to NorthWestern Energy for use by its customers in South Dakota. Phase I will utilize 10 Clipper C89 wind turbines each with a rated capacity of 2.5 MW. The project will employ up to 175 workers during peak construction and is expected to be in commercial operation in the first quarter of 2010. The balance of the plant contract has been awarded to Mortenson Construction.

“BP’s approach to meeting America’s future energy needs includes oil, natural gas and significant investments in alternative energy such as wind power, as this project demonstrates,” says John Graham, president, BP Wind Energy. “Large wind farms such as Titan are the long-term future of the wind energy business but to deliver on this opportunity, we have to address the transmission challenges and we commend those who are actively working to enable South Dakota to reach its full wind development potential,” adds Graham.

“We take seriously our responsibilities to the environment and to our customers,” says Bob Rowe, president and CEO, NorthWestern Energy. “This wind farm will provide approximately 5% of the total energy supply used by our South Dakota customers.

Moody’s cited as a reason for its upgrade an analysis that indicates regulated utilities have defaulted at a lower rate and experienced lower loss given default rates than non-financial, non-utility corporate issuers.

NorthWestern Reports Second Quarter 2009 Results

web@northwestern.com — Wed, 29 Jul 2009 05:00:15 GMT

Reports diluted EPS of $.17/share compared with $.24/share in 2Q 2008
Reduces guidance for 2009 to be $1.75 - $1.85 per fully diluted share from $1.85 - $2.00 per fully diluted share

Sioux Falls, S.D. – July 29, 2009 – NorthWestern Corporation d/b/a NorthWestern Energy (NYSE: NWE) reported financial results for the quarter ended June 30, 2009.

Significant achievements for the quarter include:

Received approval from the MPSC to construct the proposed 150 MW Mill Creek Generating Station project with a 50% debt and 50% equity capital structure, return on equity at 10.25% and debt at 6.5%; and
Amended and restated the revolving credit facility to increase the amount to $250 million from the current $200 million and to extend the maturity date to June 30, 2012 from November 1, 2009.

Financial Results

Consolidated net income was $6.1 million or $.17 per diluted share for the quarter ended June 30, 2009, compared with consolidated net income of $9.5 million or $.24 per diluted share for the quarter ended June 30, 2008. Computed diluted shares were 36.3 million at June 30, 2009 compared with 39.4 million diluted shares at June 30, 2008.

Consolidated net income for the six months ended June 30, 2009 was $28.9 million, a decrease of $4.1 million or 12.4%, from $33.0 million in 2008.

“During the second quarter of 2009, we experienced economy-driven weakness in non-firm wholesale transmission revenues in Montana and wholesale power prices in South Dakota when compared with the second quarter of 2008,” said Bob Rowe, President and CEO. “We continue to maintain a strong balance sheet. We recently bolstered our liquidity by issuing debt to facilitate execution of our capital projects, specifically including the Mill Creek Generating Station currently under construction. Finally, we are continuing to work to take actions now to focus on discretionary spending to address the declining gross margins.”

Consolidated gross margin for the second quarter of 2009 was $128.9 million compared with $127.2 million for the second quarter of 2008. The improvement in consolidated gross margin was substantially due to the transfer of our interest in Colstrip Unit 4 to Montana utility rate base and represents our return on rate base. This improvement was offset by decreases in electric transmission, electric wholesale and natural gas margins primarily due to lower demand, as a result of economic conditions and mild weather.

Consolidated gross margin for the six months ended June 30, 2009 was $291.8 million compared with $284.0 million in the same period of 2008.

Consolidated operating, general and administrative expenses increased to $60.9 million for the quarter ended June 30, 2009 as compared with $53.9 million for the quarter ended June 30, 2008. The increase was due primarily to increased labor and benefit costs due to compensation increases, severance costs, and higher post-retirement benefit costs combining for an increase of approximately $3 million. In addition, the Company experienced approximately $2.9 million higher pension expense in the second quarter of 2009 compared with the second quarter of 2008 based on our funding projections and a revised MPSC pension accounting order issued during the fourth quarter of 2008. The Company also recorded a $3.5 million insurance recovery during the second quarter of 2009 related to previously incurred Montana generation related environmental remediation costs, partially offset by a $1.8 million insurance recovery during the second quarter of 2008.

Consolidated operating, general and administrative expenses were $126.3 million for the six months ended June 30, 2009 as compared with $113.9 million in same period of 2008.

Property and other taxes were $18.2 million for the three months ended June 30, 2009 as compared with $20.5 million in the second quarter of 2008. For the six months ended June 30, 2009, property and other taxes were $42.5 million compared with $44.2 million in the same period of 2008. The decreases were due to lower assessed property valuations.

Depreciation expense was $22.3 million for the three months ended June 30, 2009 as compared with $21.2 million in the second quarter of 2008. For the six months ended June 30, 2009, depreciation expense was $45.0 million compared with $42.3 million in the same period of 2008. These increases were primarily due to plant additions.

Interest expense for the three months ended June 30, 2009 was $18.0 million, an increase of $2.2 million from the second quarter of 2008. For the six months ended June 30, 2009, interest expense was $33.1 million compared with $31.8 million in the same period of 2008. These increases were primarily related to an increase in long-term debt outstanding.

Income tax expense for the three months ended June 30, 2009 was $3.6 million as compared with $6.0 million in the second quarter of 2008. Our effective tax rate for 2009 was 36.9% as compared with 38.7% for 2008. For the six months ended June 30, 2009, income tax expense was $16.7 million compared with $19.2 million in the same period of 2008.

Results from Regulated Operations

Regulated electric gross margin for the quarter ended June 30, 2009 was $101.8 million, up 10.9%, compared with $91.8 million for the same period of 2008. This improvement is primarily due to the transfer of Colstrip Unit 4 from the unregulated electric segment to the regulated utility, which will help provide rate stability for our customers. This transfer is reflected as an increase in retail revenue and a reduction to cost of sales. Prior to the transfer of Colstrip Unit 4, all of our Montana electric supply costs were based on power purchase agreements, which are passed through to customers at actual cost with no return component. In addition, the unregulated electric margin for the same period of 2008 included an unrealized loss on a forward electric sales contract of $5.2 million. This increase in electric margin was offset in part by lower transmission volumes with less demand to transmit energy for others across our lines, a decrease in wholesale margin due to lower sales at lower average prices, and higher qualifying facility (QF) supply costs based on actual QF pricing and output.

Regulated retail electric volumes for the quarter ended June 30, 2009 totaled 2,298,000 megawatt hours compared with 2,370,000 megawatt hours for the quarter ended June 30, 2008, a 3.0% decrease. The decrease was due to a combination of economic conditions and mild weather partially offset by growth in the number of residential and commercial customers. Wholesale electric volumes were 154,000 megawatt hours for the quarter ended June 30, 2009, an increase from 82,000 megawatt hours for the same period in 2008. The increase was primarily due to the transfer of Colstrip Unit 4 to the regulated utility, partially offset by a decrease in South Dakota wholesale volumes from lower plant availability.

Regulated electric gross margin for the six months ended June 30, 2009 was $215.1 million, up 16.1%, compared with $185.3 million for the same period of 2008 generally for the same reasons as the increase in the second quarter discussed above.

Regulated retail electric volumes for the six months ended June 30, 2009 totaled 4,961,000 megawatt hours compared with 5,005,000 megawatt hours for the six months ended June 30, 2008. Wholesale electric volumes were 397,000 megawatt hours for the six months ended June 30, 2009, an increase from 131,000 megawatt hours for the same period in 2008.

Regulated natural gas gross margin was $28.5 million for the quarter ended June 30, 2009 compared with $30.6 million during the second quarter of 2008. Regulated retail natural gas volumes were 5,417,000 dekatherms for the quarter ended June 30, 2009 compared with 6,055,000 dekatherms for the same period in 2008. The decline in gross margin and volumes is primarily due to warmer weather in all service territories.

Regulated natural gas gross margin was $78.4 million for the six months ended June 30, 2009 compared with $81.0 million during the same period of 2008.

Regulated retail natural gas volumes were 19,287,000 dekatherms for the six months ended June 30, 2009 compared with 20,227,000 dekatherms for the same period in 2008. The decline in gross margin and volumes is primarily due to warmer weather in Montana and Nebraska.

Liquidity and Capital Resources

As of June 30, 2009, cash and cash equivalents were $23.0 million compared with $11.3 million at Dec. 31, 2008. As of June 30, 2009, our total net liquidity was approximately $269.3 million, compared with $ 86.2 million at Dec. 31, 2008. The increase in liquidity was due primarily to issuance of $250 million of Montana First Mortgage Bonds in March 2009 and an amendment to the unsecured revolving line of credit that increased the availability under that line from $200 million to $250 million.

Cash provided by operating activities totaled $85.4 million for the six months ended June 30, 2009 as compared with $124.6 million during the six months ended June 30, 2008. This decrease in operating cash flows is primarily related to increased pension funding of approximately $41.3 million and a $10.8 million prepayment of a power purchase agreement, offset by lower commodity prices reflected in the change in accounts receivable and accounts payable, as well as decreased cash outflows for natural gas storage injections.

Cash used in investing activities during the six months ended June 30, 2009 increased by approximately $3.5 million as compared with 2008 due to increased property, plant and equipment additions. Capital expenditures for the six months ended June 30, 2009 were $46.9 million as compared with $43.1 million in the same period of 2008.

Cash used in financing activities totaled approximately $27.2 million during the six months ended June 30, 2009 as compared with $70.1 million during the six months ended June 30, 2008. During the first half of 2009, the Company received net proceeds from the issuance of debt of $249.8 million, made net debt repayments of $243.0 million, paid deferred financing costs of $9.9 million and paid dividends on common stock of $24.1 million. During the six months ended June 30, 2008, the Company made net debt repayments of $42.9 million and paid dividends on common stock of $25.7 million.

2009 Earnings Outlook

NorthWestern reduces its earnings outlook for 2009 to be $1.75 - $1.85/fully diluted share from previous guidance of $1.85 - $2.00/fully diluted share.

The major assumptions include, but are not limited to, the following expectations:

Reduced off-system transmission revenues in Montana for the remainder of 2009
2009 net income will increase by approximately $9 million or $.25 per share as a result of the inclusion of our interest in Colstrip Unit 4 in regulated electric rate base;
Pension expense based on an assumed 8% return on plan assets for 2009;
Retail electric volumes will be flat compared with 2008 volumes;
Wholesale electric volumes in South Dakota will decrease due to pricing and volume reductions;
Residential and Commercial natural gas volumes will be relatively flat compared with 2008 volumes;
Fully diluted average shares outstanding of 36.5 million; and
Normal weather in the Company’s electric and natural gas service territories for the rest of 2009.

NorthWestern Energy Notifies the Billings Area of a Potential Water Hazard on the Yellowstone River

web@northwestern.com — Tue, 30 Jun 2009 16:40:47 GMT

Billings , Mont. – June 30, 2009 – NorthWestern Energy is notifying the public of a potential water hazard south of the Laurel Yellowstone River Bridge. A power line located on an island in the river is down and crews are in the process of installing a new pole and resetting the wires.

Those navigating the Yellowstone River today and tomorrow, should avoid the North Channel area as crews work to repair the line. The line is de-energized; however, it could become a potential hazard to those trying to navigate the affected stretch. The affected area is approximately three to four miles downstream (east) of the Laurel Yellowstone River Bridge, which is located on Highway 312 south of the CHS refinery. The South Channel of the Yellowstone River is clear for watercraft to navigate.

Customers with questions may call the NorthWestern Energy Customer Contact Center at (888) 467-2669.

NorthWestern Energy Notifies Billings Customers of Maintenance Work

web@northwestern.com — Thu, 25 Jun 2009 11:02:46 GMT

Billings, MT – June 25, 2009 – NorthWestern Energy is installing replacement underground electric cable in the Woodward Way Subdivision in the Lockwood area of Billings. This replacement of aging underground cable is part of our ongoing commitment to providing exceptional service and reliability for all of our electric customers.

Beginning June 29 and continuing through July and August, crews will be accessing utility rights of way along property lines in the residential neighborhoods to install the cable. The project will start with properties on Westgate Drive. The entire cable replacement project is expected to take up to two months and will eventually include cable replacement in backyards of Lockwood property owners on Kingswood, Fleetwood, Brookwood, Noblewood and Tanglewood Drives.

Underground locates will be done in advance of the work. It is important that homeowners do not remove the underground locates on their property. In many cases, the new cable will be installed by boring under the surface to minimize disrupting the landscaping. Customers should experience little or no disruptions to their electric service.

Crews will be clearly identified, but should landowners in the area have any questions about our work, or our access to rights of way, please do not hesitate to call our Customer Contact Center at (888) 467-2669.

NorthWestern Energy Responds to FERC Orders on Transmission Projects

web@northwestern.com — Tue, 23 Jun 2009 12:02:37 GMT

Butte, Mont. – June 23, 2009 – NorthWestern Corporation d/b/a NorthWestern Energy (NYSE:NWE) plans to conduct “Open Seasons” as planned for two major transmission projects following the Federal Energy Regulatory Commission’s (FERC) recent action on the company’s petitions.

FERC affirmed its support of the company’s efforts to build new transmission on congested pathways. FERC encouraged the company to develop the Mountain States Transmission Intertie (MSTI Project) on a cost of service basis by requesting appropriate tariff waivers to provide for the flexibility to efficiently and effectively facilitate the project development. FERC also agreed with the company’s proposed pricing for the Collector Project and the general approach for the Collector open season process.

“The FERC Orders are complex and required time to fully sort through all of the details,” said Dave Gates, Vice President – Wholesale Operations. “However, after careful review, we regard the Orders as providing necessary guidance from FERC and supporting the development of both projects. Accordingly, we will continue to develop the projects without delay or interruption.”

In requesting market-based rates for MSTI, NorthWestern Energy followed the approach that FERC has approved for similar projects in the region, including the Montana-Alberta Tie Line and TransCanada’s proposed Chinook project. NorthWestern Energy believed that this approach would provide it with flexibility to meet market conditions and would best insulate its native load customers from the costs and risks of the project. Although FERC denied the company’s request, it provided strong encouragement for continuing with the project using a more traditional approach.

To quote the Order, “ We also recognize the Petitioners’ desire to insulate native load customers from the costs and risks associated with an export-only project…we believe that NWE has ample opportunity to accomplish its objectives and construct a project comparable to the MSTI proposal on a cost-of-service basis by requesting appropriate tariff waivers.” In support of the MSTI Project, FERC further noted “…we acknowledge the need for innovative proposals to develop new transmission projects, especially in regions rich in potential to deliver renewable energy to load centers.”

As to the Collector, FERC approved NorthWestern’s proposal to directly assign the cost of the project to the generators. This has the effect of insulating native load customers from the cost of the project. While FERC deferred ruling on NorthWestern’s request for waivers, FERC specifically found the proposed open season process to be a reasonable means of accommodating a large number of interconnection requests in the queue.

The open seasons for the MSTI and Collector projects will be conducted on a transparent basis in order to ensure fairness and non-discriminatory access. The results of the open seasons will be used to size the projects according to customer demand. The open season process will also ensure that the projects have sufficient contracts with credit-worthy shippers to support financing.
With more than 5,000 megawatts of proposed new electric generation – much of it wind energy - that has sought access to the transmission system in Montana, the company has proposed two major projects – MSTI and the Collector Project - to facilitate development of these projects.

The Collector Project consists of up to five new transmission lines in Montana that would connect new generation, primarily wind farms, to the existing NorthWestern Energy transmission system and to the proposed Mountain States Transmission Intertie (MSTI). Most of the new proposed wind generation that would be served by the collector system would be located in north central, central, south central and eastern Montana.

MSTI is a proposed 500kV transmission line that would run near Townsend, Montana to near Midpoint, Idaho. The project is currently undergoing environmental review with a draft Environmental Impact Statement due in late-2009.

NorthWestern Energy Unveils Hybrid Bucket Truck in Missoula

web@northwestern.com — Wed, 10 Jun 2009 10:01:21 GMT

Butte , Mont. – June 10, 2009 – NorthWestern Energy’s (NYSE: NWE) commitment to environmentally responsible practices extends to its vehicle fleet. The company has added hybrid vehicles to its fleet in recent years and today unveiled its first hybrid bucket truck, which will begin working the streets of Missoula and surrounding communities later this week.

The hybrid technology saves fuel and also allows the truck’s diesel engine to be shut down while crews perform line repair and maintenance work relying on the vehicle’s batteries to operate the aerial lift. Drawing on the battery power eliminates both noise and diesel exhaust.

“This new hybrid bucket truck costs about $45,000 more than a standard truck, but will go about twice the distance before needing to refuel depending on driving and work conditions,” said Ron Anderson, NorthWestern Energy’s manager of fleet and equipment. “It also produces about half the emissions of a conventional vehicle, which is – quite literally – a breath of fresh air for a work truck.”

The 40-foot, 26,000-pound hybrid bucket truck has an aerial lift of 42 feet and replaces an older vehicle that NorthWestern will retire from its companywide fleet of 947 vehicles. The company began adding hybrid service vehicles to its fleet three years ago. It plans to continue replacing service vehicles with hybrids as appropriate and plans to add another hybrid bucket truck to the fleet later this year.

“While this is the first hybrid bucket truck in the fleet,” Anderson said, “we continue to operate our other conventional trucks with safety and environmental responsibility in mind. The crews are mindful of idling trucks only to the extent necessary to do their work safely and we’ve implemented various operational changes over the years to reduce fuel consumption. We are always looking for new approaches to sustainable and cost-effective fleet management practices.”

NorthWestern Energy Annual Natural Gas Inspections Underway Across Montana

web@northwestern.com — Mon, 08 Jun 2009 07:58:15 GMT

Butte , Mont. – June 8, 2009 – NorthWestern Energy’s natural gas distribution and transmission systems are undergoing their annual safety inspections across Montana.

The company owns and operates more than 6,000 miles of natural gas pipelines that transport and deliver natural gas to approximately 179,200 customers in Montana. Federal and state regulations require the company to conduct regular, routine inspections of the facilities as part of the company’s operation, maintenance and safety programs.

Contractors working on behalf of the company are currently conducting annual leak surveys on the distribution systems in each community. Commercial districts are surveyed annually while residential areas are surveyed every four years. Surveyors using equipment that looks similar to a metal detector walk above the pipelines placing the “sniffers” to the ground every few feet. The sensitive equipment alerts the surveyor if it detects even the smallest presence of natural gas in the soil. Servicemen follow up on any positive readings to find the source and to make any fixes that may be necessary.

In addition, the company has individuals conducting pipe-to-soil surveys that test steel pipes for adequate protection. This also involves an individual walking through residential areas and occasionally entering yards to conduct field tests and measurements. The pipe-to-soil survey is part of the company’s cathodic protection program that is designed to protect underground steel pipes from corrosion.

On the transmission system, contractors and employees are patrolling the pipelines looking for anything out of the ordinary that might suggest a leak, damage, or potential problem such as a washout.

In all cases, NorthWestern Energy employees and contractors drive vehicles and wear clothing that identify them as official company representatives and carry some form of company identification (i.e. business card, access key card, etc.). However, please alert NorthWestern Energy or law enforcement immediately if you witness suspicious individuals or activities near or around our facilities.

As a reminder, customers are responsible for the maintenance of gas pipes that lead from the gas meter to various locations or appliances on the property such as a detached garage or barbeque grill. If you find anything out of the ordinary on your property, such as bubbling ponds or dead/discolored vegetation in an otherwise green area near a location of an underground pipe, you should contact a qualified service technician to perform any needed repairs.

If you smell natural gas, please notify NorthWestern Energy or call 911. From a safe location call NorthWestern Energy’s emergency number: (800) 467-2427 Calls can be made 24 hours a day, seven days a week – we will respond promptly – at no charge.

Do NOT attempt to locate the leak.
Do NOT use any phone (even your cell phone) within the house or building.
Do NOT turn on or off any battery-powered, rechargeable or electrical device, including telephones, garage door openers, televisions, computers or any electrical appliance that could create a spark.

NorthWestern Energy to Send Scratch and Sniff Odorant Cards as Customer Safety Reminder

web@northwestern.com — Wed, 27 May 2009 07:28:43 GMT

Huron, S.D./Butte, Mont. – May 27, 2009 – NorthWestern Energy will include scratch and sniff cards in June monthly bills to remind customers of the distinctive smell that is used to help identify natural gas leaks. To help customers detect natural gas-like leaks more easily, NorthWestern adds mercaptan, a chemical odorant, which gives natural gas its distinctive, sulfur-like aroma. Natural gas itself has no odor.

If people smell natural gas inside or outside of a house or building, they should leave the premises immediately and call the company’s 24-hour emergency service line from a neighbor’s house or other safe location, toll-free, at (888) 467-2427 in Montana and (800) 245-6977 in South Dakota and Nebraska or 911. Calls can be made 24 hours a day, seven days a week – NorthWestern will respond promptly – at no charge.

“We are reminding our customers of this important safety measure as part of our long-standing commitment to providing them safe, reliable natural gas service,” explained Bob Rowe, President and CEO of NorthWestern Energy.

In case of a natural gas leak or other emergency situation, NorthWestern Energy urges that customers:

Do NOT attempt to locate the leak.
Do NOT use any phone (even your cell phone) within the house or building.
Do NOT turn on or off the lights or any battery-powered, rechargeable or electrical device, including telephones, garage door openers, televisions, computers or any electrical appliance that could create a spark.

From a safe distance, watch for the NorthWestern truck so you can let the service representative into your home or building.

MPSC Issues Final Order Approving NorthWestern's Mill Creek Generating Station

web@northwestern.com — Tue, 19 May 2009 14:50:47 GMT

Sioux Falls, S.D./Butte, Mont. – May 19, 2009 – The Montana Public Service Commission (MPSC) has formally approved the Company’s construction of the Mill Creek Generating Station (MCGS) near Anaconda, Montana.

“We appreciate the commission’s thoughtful and thorough deliberation. This is our first new electric generating resource in Montana, and is a key step towards our vision of being a fully integrated, regulated utility. It will enable us to integrate additional wind and other resources on the system,” said Bob Rowe, NorthWestern Energy’s President and CEO.

The 150 megawatt Mill Creek Generating Station is intended to provide regulating resources to balance the company’s energy supply and transmission system in Montana to maintain reliability and enable additional wind power to be integrated onto the network to meet its current renewable energy portfolio needs. The facility is designed to enable increasing or decreasing energy production within seconds to follow load fluctuations on the system.

“This plant will help us achieve many of the objectives that are important to us and to our customers including energy supply and transmission stability and reliability as we integrate renewable energy on to our system. We also intend to work with local residents throughout the construction process to ensure that we continue to be a good neighbor,” Rowe added.

Among other actions, the commissioners determined the $81 million cost of the turbines was prudent, approved the plant’s return on equity at 10.25 percent and debt at 6.5 percent with a 50/50 capital structure and accepted the plant’s carbon offset plan as filed. The plant is estimated to cost approximately $201 million; the remainder of the costs will be submitted to the MPSC for review and approval once the plant is complete.

The company is in the process of obtaining bids and contracts from vendors and will commence construction this fall. The plant is scheduled to go into operation by December 31, 2010.

Thank You, Butte!

web@northwestern.com — Mon, 27 Apr 2009 17:02:47 GMT

Guest Opinion
Bob Rowe, President and CEO, NorthWestern Energy

Butte, MT — April 27, 2009 — Last week, NorthWestern Energy celebrated its history in Butte. We could not have been prouder! With warm temperatures, blue skies, and fresh snow on the mountains, even the weather was on its best behavior – at least for a few days.

Our annual Shareholders’ Meeting was held in Butte for the first time. Shareholders’ meetings are serious and formal affairs, as they should be, but they are also opportunities to bring shareholders, employees and customers together. This is why we decided to hold the meeting in our largest employee location within our service territory. Next year we’ll do the same thing in South Dakota.

As importantly, our Board of Directors spent two days in Butte, working hard, meeting with our employees and retirees, and getting to know Butte’s community leaders, citizens and history. Several of our Board members also attended a legislative reception in Helena, or traveled to meet with our employees in Cut Bank, Havre and Lewistown.

We have a hard working, national-caliber Board of Directors, with experience in energy, finance, human resources and corporate governance. Our two newest members, Dorothy Bradley and Dana Dykhouse, bring first-hand experience in Montana and South Dakota with the economic development, public policy, and other opportunities and challenges that face our communities.

Montana Tech and Chancellor Gilmore hosted our Board meeting, Shareholders’ meeting, and a community discussion with our Board and executive team. From there, we marched up Park Avenue to the Museum of Fine Arts Butte, for a reception honoring our retirees and employees. From the MOFAB, we crossed the street to the Motherlode, for a special showing of Butte America, Pam Robert’s remarkable history of the workers who made Butte the Richest Hill on Earth. Former Congressman Pat William’s introduction, including his own story of growing up in Butte, helped connect history to today’s events. Our Board members ended the day eating pasties at the Copper King Mansion.

Many of our employees had family who worked in the underground mines (my grandfather worked underground in the Anselmo until a ripe old age), and Butte America was filled for them with familiar faces and important stories. Although Butte America is about mining and Anaconda, not energy, there are important connections and key distinctions. Butte became “the richest hill” based mainly on copper to transmit electricity. The Montana Power Company’s fortunes rose and fell in significant part based on Anaconda’s business plans. “The Company” (Anaconda) was “the Power’s” largest customer. When mining shut down, it was a tough blow for the Montana Power Company, as well as for Butte and for Montana.

I was struck by some important differences between then and now as well. NorthWestern Energy honors and respects its employees – both union and nonunion. We try to do our work, providing energy infrastructure and service, in an environmentally responsible way. Our business is focused on providing value to our customers, both retail and wholesale, in our service territory. We serve 349 communities in Montana, Nebraska and South Dakota. Our Montana employees live in 53 communities across our Montana territory.

Butte was at technology’s cutting edge in the early years of the Twentieth Century providing electricity to the mines, natural gas to the community, and copper to the world. With its academic base and technology firms, including NorthWestern Energy, we are prepared to contribute in the Twenty-first Century as well, in key areas such as renewable resources, and helping the nation address its energy and environmental challenges.

In Butte, we have over 500 employees, in locations from uptown to the flats making it the largest employee presence anywhere in the company. Our largest network operation center and customer service center are here. Retail gas and electric service, energy supply, transmission, and other key aspects of operational support are based in our uptown office. Our Butte district office is responsible for gas and electric delivery to much of southwest Montana. Our Butte-Silver Bow payroll is $37 million (of an $80 million total Montana payroll). Our local tax payments are $6.8 million (of $77 million in Montana taxes). As importantly, our employees are active contributors to most every major civic project in the area.

I’m proud of both our Butte history and our current role in this extraordinary community. It was an honor last week to be able to share and celebrate NorthWestern Energy’s place in Butte, and especially our great people. Thanks Butte!

NorthWestern Energy Opens Recovery Office in Downtown Bozeman

web@northwestern.com — Thu, 23 Apr 2009 15:46:58 GMT

Butte, Mont. – April 23, 2009 – NorthWestern Energy today announced that is opening a temporary office in Downtown Bozeman to provide local business owners and residents with easy access to information related to the recovery effort.

The company is leasing the space located at 308 Main Street to provide the public with information about the company’s natural gas system including system integrity and safety programs. It also will serve as a meeting place for people actively engaged in the recovery process for the next several months.

“We’re opening this temporary office in response to comments that we’ve received from Downtown business owners and local residents for ongoing information and regular contact,” said Bob Rowe, President and CEO. “This step is part of a broader effort to inform, educate and demonstrate our level of commitment to our customers and communities.”

NorthWestern Energy has been working with local residents and business owners to understand their questions and concerns following the March 5 explosion. The company has developed, through more than four-dozen interviews, a comprehensive response plan to restore confidence in the company’s natural gas system. The plan includes a public outreach effort to inform and educate customers about the company’s natural gas system.

“We continue to investigate the incident and expect that it will take between three to six months to gather the necessary facts and analyze the pipe, soil, weather conditions, and customer piping in order to determine what caused the fracture at a coupling in a two inch service line,” added Rowe.

NorthWestern Energy has published a website specific to the recovery effort at http://www.bozemanrecovery.com/ and updates the site regularly as information is available. The Downtown Bozeman office is specific to the recovery effort and is not a customer payment location. The office is expected to open to the public on May 1.

NorthWestern Reports First Quarter 2009 Results

web@northwestern.com — Thu, 23 Apr 2009 07:00:00 GMT

Sioux Falls, S.D. – Apr. 23, 2009 – NorthWestern Corporation d/b/a NorthWestern Energy (NYSE: NWE) reported financial results for the quarter ended March 31, 2009.

Highlights for the quarter include:

Reports net income of $22.8 million, or $.63/diluted share, compared with net income of $23.5 million in 1Q 2008, or $.59/diluted share;

The increase in EPS was due primarily to the share buy back concluded in the third quarter of 2008.

Moody’s Investors Service (Moody’s) upgraded the senior secured to Baa1 from Baa2 and unsecured credit ratings to Baa2 from Baa3;
Issued $250 million of First Mortgage Bonds at 6.34% due in 2019;

As of March 31, 2009, total net liquidity was approximately $260.0 million, including $83.2 million of cash and $176.8 million of revolving credit facility availability.

Total net liquidity increased to approximately $260 million as of March 31, 2009;
Montana Public Service Commission (MPSC) conducted hearings related to our proposed Mill Creek Generation Station and a decision is expected in the second quarter of 2009;
Placed our ownership interest in Colstrip Unit 4 into utility rate base at a value of $407 million, pursuant to a 2008 MPSC order; and
Gross Margin increased to $162.9 million for the first quarter of 2009 compared with $156.9 million for the same period of 2008.

First Quarter Financial Results

Consolidated net income was $22.8 million or $.63 per diluted share for the quarter ended March 31, 2009, compared with consolidated net income of $23.5 million or $.59 per diluted share for the quarter ended March 31, 2008. Computed diluted shares were 36.3 million at March 31, 2009 compared with 39.4 million diluted shares at March 31, 2008. The decrease in the number of computed diluted shares is due to a share buyback conducted in the third quarter of 2008.

“During the first quarter of 2009, our gross margin, electric volumes and our customer counts all improved when compared with the first quarter of 2008,” said Bob Rowe, President and CEO. “Also, indicative of our continued improving financial condition and the fact that we have essentially completed our goal of exiting all non-regulated business activities, Moody’s upgraded our debt in January 2009.”

Consolidated gross margin for the first quarter of 2009 was $162.9 million compared with $156.9 million for the first quarter of 2008. The improvement in consolidated gross margin was primarily due to the transfer of our interest in Colstrip Unit 4 to Montana utility rate base and represents our return on rate base. Gross Margin (Revenues less Cost of Sales) is a non-GAAP financial measure due to the exclusion of depreciation from the measure. The presentation of Gross Margin is intended to supplement investors’ understanding of our operating performance. Our Gross Margin measure may not be comparable to other companies’ Gross Margin measure.

Consolidated operating, general and administrative expenses increased to $65.4 million for the quarter ended March 31, 2009 as compared with $60.1 million for the quarter ended March 31, 2008. The increase was due primarily to increased insurance reserves, higher pension expense related to our Montana plan, and increased labor and benefit costs due to a combination of compensation increases and severance costs.

Property and other taxes were $24.3 million for the three months ended March 31, 2009 as compared with $23.6 million in the first quarter of 2008. The increase was due to higher estimated property valuations.

Depreciation expense was $22.7 million for the three months ended March 31, 2009 as compared with $21.1 million in the first quarter of 2008. This increase was primarily due to 2008 plant additions.

Interest expense for the three months ended March 31, 2009 was $15.1 million, a decrease of $1.0 million, or 6.2%, from the first quarter of 2008. This decrease was primarily related to lower interest rates on our variable rate debt.

Income tax expense for the three months ended March 31, 2009 was $13.1 million as compared with $13.2 million in the first quarter of 2008. Our effective tax rate for 2009 was 36.4% as compared with 36.0% for 2008.

Results from Operations

Regulated electric gross margin for the quarter ended March 31, 2009 was $113.2 million, up 20.9%, compared with $93.6 million for the same period of 2008. This improvement is primarily due to the transfer of Colstrip Unit 4 to the regulated utility, which is reflected as an increase in retail revenue and a reduction to cost of sales. Prior to the transfer of Colstrip Unit 4, its results were reflected in the unregulated electric segment through December 31, 2008,

Regulated retail electric volumes for the quarter ended March 31, 2009 totaled 2,663,000 megawatt hours compared with 2,634,000 megawatt hours for the quarter ended 2008, a 1.1% increase. The increase was due primarily to residential and commercial customer growth. Wholesale electric volumes were 243,000 megawatt hours for the quarter ended March 31, 2009, an increase from 49,000 megawatt hours for the same period in 2008. The increase was primarily due to the transfer of Colstrip Unit 4 to the regulated utility from the unregulated electric segment.

Regulated natural gas gross margin was $49.9 million for the quarter ended March 31, 2009 compared with $50.3 million during the first quarter of 2008. Regulated retail natural gas volumes were 13,870,000 dekatherms for the quarter ended March 31, 2009 compared with 14,172,000 dekatherms for the same period in 2008. The decline in gross margin and volumes is primarily due to warmer winter weather in Montana and Nebraska. Liquidity and Capital Resources

As of March 31, 2009, cash and cash equivalents were $83.2 million compared with $11.3 million at Dec. 31, 2008. The Company had $176.8 million available from credit facilities at March 31, 2009 compared with $74.9 million at Dec. 31, 2008. The increase in credit revolver availability was due primarily to issuance of $250 million of Montana First Mortgage Bonds in March 2009. The proceeds were used to redeem the $100 million term loan held by Colstrip Lease Holdings LLC and repay outstanding borrowings on the credit facility.

Cash provided by operating activities totaled $65.1 million during the quarter ended March 31, 2009, compared with $78.0 million during the quarter ended March 31, 2008. This decrease in operating cash flows is primarily related to increased pension funding of approximately $21.3 million, offset by improvements associated with the timing of energy supply costs collections in the first quarter of 2009 as compared with 2008.

The Company used $18.2 million for investment activities during the quarter ended March 31, 2009 compared with $14.0 million for the quarter ended March 31, 2008. Capital expenditures for the quarter ended March 31, 2009 were $18.5 million as compared with $14.0 million in 2008.

The Company’s financing activities provided $25.0 million during the quarter ended March 31, 2009 compared with financing activities using $43.0 million for the quarter ended March 31, 2008. During the first quarter of 2009 the Company issued debt of $250 million, made debt repayments of $211.3 million, and paid dividends on common stock of $12.0 million. During the first quarter of 2008, we made debt repayments of $30.0 million and paid dividends on common stock of $12.9 million.

Dividend

NorthWestern’s Board of Directors declared a quarterly common stock dividend of 33.5 cents per share, payable on June 30, 2009, to common shareholders of record as of June 15, 2009.

2009 Earnings Outlook

NorthWestern reaffirms its earnings for 2009 to be $1.85 - $2.00/fully diluted share.

The major assumptions include, but are not limited to, the following expectations:

2009 net income will increase by approximately $9 million or $.25 per share as a result of the inclusion of our interest in Colstrip Unit 4 in regulated electric rate base;
Pension expense is estimated to be flat with the 2008 pension expense;
Planned insurance recoveries will offset our Q1 insurance reserve expense increase;
Retail electric volumes will be flat compared to 2008 volumes;
Wholesale electric volumes in South Dakota will decrease due to a planned outage in 2009;
Residential and commercial natural gas volumes will be relatively flat compared with 2008 volumes;
Fully diluted average shares outstanding of 36.5 million; and
Normal weather is assumed in the Company’s electric and natural gas service territories for the rest of 2009.

Results of Annual Shareholder Meeting

At its 2009 Annual Meeting of Stockholders held yesterday, NorthWestern’s stockholders elected E. Linn Draper, Jr., Stephen P. Adik, Dorothy M. Bradley, Dana J. Dykhouse, Julia L. Johnson, Philip L. Maslowe, D. Louis Peoples and Robert C. Rowe to a one-year term on the Board.

NorthWestern Energy Reminds Customers of Programs and Services for Earth Day

web@northwestern.com — Mon, 20 Apr 2009 15:19:02 GMT

Butte , Mont. – April 20, 2009 – In honor of Earth Day, NorthWestern Energy is reminding its Montana customers of the variety of programs and services that encourage Earth-friendly energy practices including a new special offer for residential electric customers, the Earth Day Lighting Coupon.

“In less than a minute, people can change out a high use incandescent bulb to a compact fluorescent light bulb (CFL) and save energy this Earth Day,” said Bill Thomas, Manager of Regulatory Support Services.

“The coupon has been mailed to all residential electric customers and is now showing up in mail boxes around Montana. The coupon enables customers to save $2 off the price of each CFL purchased at participating retailers.” The coupon is valid from April 22 through June 14, 2009.

In addition to the CFL promotion, NorthWestern Energy provides rebates for qualifying insulation improvements, ENERGY STAR programmable thermostats, and energy efficient heating equipment and improvements for its home-heating customers. Rebates are also offered when replacing a hot water tank with a high efficiency unit. Residential customers heating their homes or domestic hot water with Northwestern Energy electricity may be eligible for incentives to switch to natural gas. Rebates for lighting efficiency improvements and premium efficiency motor purchases are available to commercial electric customers. The custom incentives are offered for site-specific, cost-effective energy savings are now available for both electric and natural gas measures in new or existing commercial facilities.

Customers building new homes are encouraged to work with a builder who will build a Northwest ENERGY STAR certified home. These homes meet strict standards to be more efficient and are tested for efficiency and comfort. Visit www.northwestenergystar.com for features and a listing of Montana builders who are trained as Northwest ENERGY STAR builders.

After reducing the energy footprint through efficiency and conservation measures, renewable energy options provide other paths to pursue. NorthWestern Energy offers incentives to qualifying photovoltaic systems that maximize the use of the sun and small-scale wind projects through its Renewable Generation Programs. If installing a renewable system is not a fit, the E+ Green Power program allows customers to offset their electric usage with the environmental benefits of renewable energy generated in the Northwest for as little as $2 a month.

“Every day is Earth Day and NorthWestern Energy’s Efficiency Plus, or E+ Programs, provide many opportunities for our customers who are looking to take action,” said Thomas.

NorthWestern Energy is participating in the 2009 Energy Conservation Fair in the Capitol Rotunda from 9 a.m. – 3 p.m. on Earth Day, April 22. The event is sponsored by the Montana Department of Labor and Industry. NorthWestern Energy will have information about its energy efficiency and renewable generation programs at the event.

The EIS Process is Working

web@northwestern.com — Wed, 08 Apr 2009 16:21:17 GMT

Guest Opinion
Dave Gates — Vice President, Wholesage Operations

NorthWestern Energy is proposing to build a 500kV transmission line from Townsend to Midpoint, Idaho. We’ve been working on this project for a few years now and have held more than 60 public meetings and open houses in communities that may be impacted by proposed line, including here in Butte.

The Mountain States Transmission Intertie (MSTI) is intended to carry power generated in Montana – mostly from proposed large wind farms – to markets around the West that want that power to meet their renewable energy needs. It is not going to be part of our Montana utility rates– therefore it is not a cost that will be borne by our retail Montana customers.

As a regional transmission operator in an interconnected grid, we are required by the federal government to provide open, non-discriminatory access to all customers and we’re obligated to build transmission to meet the changing needs of our region.

Electrical grid “modernization” is one of the Obama Administration’s highest priorities. Just as the existing grid was designed to meet the needs of the past century, MSTI and our other transmission projects are engineered to meet the needs of this century.

Montana, thanks to its abundance of natural resources and open spaces, has always provided needed commodities to the rest of the country and to the world. We are proud exporters of copper, gold, beef, wheat, and energy in all of its various forms. It’s the fuel of our economic engine and the production and export of renewable energy is another viable and important addition to our economy.

NorthWestern currently pays approximately $8 million in property taxes to Butte Silver Bow (BSB) – this line is expected to add as much as another $2 million depending on how much of it is built within the county and up to $4.8 million in new property tax revenue to Deer Lodge County by building through BSB to Mill Creek.

MSTI is currently in the siting phase, which is a federal and state governmental review process that involves a significant amount of public input for the purpose of determining the route with the least amount of environmental impacts. The process requires NorthWestern to choose a preferred route and two alternative routes and there has never been a situation when the preferred route is chosen, in its entirety, as the final route. The proposed routes all have existing transmission lines within the corridor.

Opposition to major projects such as this is inevitable and understandable – there will never be a route that satisfies everyone. The Major Facility Siting Act (MFSA), the National Environmental Policy Act (NEPA) and the Montana Environmental Policy Act (MEPA) – all of which have requirements that must be fulfilled within the Environmental Impact Statement (EIS) process recognize that fact. The process removes the human emotional component from the equation and focuses on facts, data and science.

Health concerns are evaluated as part of the EIS process as are impacts to all aspects of the environment including water, air, livestock, economy, wildlife, land use, cultural and socioeconomic. Electromagnetic fields (EMF’s) concerns are always raised in opposition to power lines. We, as do many other utilities, support further research in this field and, to date, the scientific evidence has never proven health risks associated with EMFs emitted by high-voltage power lines.

Much of the current research is looking at effects of EMFs in daily life since all electrical appliances emit EMFs often in much greater concentration that what you’ll find at the edge of a utility right of way. Montana is one of the few states that has regulations requiring utilities like NorthWestern to meet certain EMF levels on and near a power line right of way. Our high voltage lines are always engineered to fall within these regulations and MSTI will be no exception.

Currently, the Montana Department of Environmental Quality and Bureau of Land Management are reviewing all of the data and working with an independent 3rd party contractor, PBS&J, on a draft Environmental Impact Statement. This draft EIS is expected to be completed by the end of the year at which time it will go through another public process to gather input on the proposed final route. The route is subject to change until the final EIS is published next year.

We encourage public participation in this process because that is how the best route is ultimately chosen. To learn more about the project visit www.msti500kV.com.

NorthWestern Energy to Conduct Maintenance on 500kV Colstrip Transmission System

web@northwestern.com — Fri, 03 Apr 2009 09:59:26 GMT

Butte , Mont. – April 3, 2009 – Beginning April 6, NorthWestern Energy crews begin the routine annual maintenance cycle on the 500kV Colstrip Transmission System. This year’s work will include the replacement of conductor spacers, which are brackets that keep the lines from inadvertently making contact, on the spans between Broadview and Colstrip, Montana.

Landowners and residents in the area may notice men and equipment on the towers and traveling the lines in spacer carts. NorthWestern Energy vehicles and equipment, as well as clearly marked contractor vehicles, will be accessing rights of way throughout this period. Helicopters will also be working in the area delivering material and providing support to the crews working on the towers and lines. The work is done on live lines during daylight hours Monday through Friday and occasionally on Saturday, weather permitting, through May 9.

The company makes every effort to control the spread of noxious weeds by washing all vehicles and equipment daily prior to entering the right of way. Upon completion of the work, the right of way technicians inspect the area and apply an herbicide to further minimize the potential spread of seeds.

Landowners with questions or concerns about right of way access should contact Wayne Clark 406-860-1757.

Dorothy M. Bradley to Stand for Election at NorthWestern Energy’s 2009 Annual Meeting of Stockholders

web@northwestern.com — Thu, 19 Mar 2009 14:54:16 GMT

Sioux Falls, S.D. – March 19, 2009 – NorthWestern Corporation d/b/a NorthWestern Energy (NYSE:NWE) today announced that Dorothy M. Bradley will stand for election to the Board of Directors at the Company’s 2009 Annual Meeting of Stockholders to be held on April 22, 2009, in Butte, Mont. Bradley resides in Clyde Park, Mont., and will fill the vacancy on the Board left by Montana resident Jon Fossel, who chose not to stand for re-election at this year’s annual meeting.

According to NorthWestern President and CEO Bob Rowe, “Dorothy’s strong background in public policy and her lifelong commitment to Montana and its people will strengthen NorthWestern’s ability to serve Montana, and indeed all of our stakeholders.”

“My selection to serve on the Board of NorthWestern Energy is an immense honor, opportunity, and responsibility,” said Bradley. “At no other time have energy and utility issues been so critical for Montana and the nation. NorthWestern is working in new ways to reach out to its Montana stakeholders, to hear from them, and to be a respected part of the Montana family. I look forward to joining this worthy effort alongside CEO Bob Rowe, a long-respected Montana leader, as well as a group of exceptional Board members.”

“I thank Jon Fossel for his service on the Board over the past four-plus years,” said Rowe. “Jon provided great wisdom and experience as a Board member and helped NorthWestern through difficult times to become the sound company it is today. I will continue to look to him for good counsel.”

As a citizen legislator and community leader, Bradley has spent most of her life working for the people of Montana. She was elected as the only woman in the Montana House of Representatives in 1971 at the age of 23 and has proven herself to be an independent leader who is not afraid to address hard problems. Throughout her career in public service and 16 years in the House, Bradley has tackled complex and controversial issues including tax reform, natural resources policy, telecommunications modernization, science-and-technology-based economic development, and health care, and gained recognition for her consensus-building approach. During her later sessions, she chaired the Appropriations Subcommittee on Human Services, beginning its enduring tradition of an equal partisan membership.

Bradley left the state legislature in 1992 to run for Montana’s governorship. After winning the Democratic primary, she lost the November election by a small margin. Bradley continued her service to the people of Montana, spending half a year teaching in a small, rural school in Ashland, next to the Northern Cheyenne Indian Reservation. In the summer of 1993, Bradley was appointed to the newly formed Montana Health Care Authority, and was elected by the members to serve as Chair. Also in 1993, Bradley was hired by Montana State University to become Director of the University System Water Center, a post she held for seven years. The mission of the Center is to promote research, education, and outreach on Montana water issues. Beginning the effort with an office of two and growing to eight, the Center developed a number of distinguished programs under her directorship, including whirling disease research, a national wild fish partnership, and a drinking water education program.

From 2000 to 2007, Bradley was the District Court Administrator for the 18th Judicial District and staff for the County’s Criminal Justice Coordinating Council (CJCC). The CJCC is composed of 10 key officials in Gallatin County’s criminal justice system along with 12 advisors, whose mandate is to serve as the central criminal justice planning body and make recommendations to public policy boards regarding deficiencies and needed changes. Changes brought about through the leadership of the CJCC include a Re-Entry Facility and a new department of Court Services with pretrial, post trial and treatment programs.

Bradley grew up in Bozeman, Mont., received a B.A. in Anthropology from Colorado College in 1969 (Phi Beta Kappa and Distinction in Anthropology), and acquired a law degree from American University in 1983. She has been recognized with an Honorary Doctorate from Colorado College, Business Woman of the Year from the Bozeman Chamber and MSU Alumni Association, and Woman of Achievement from the Montana Business and Professional Women.

Winners of the First Annual Montana BetterBricks Awards Announced

web@northwestern.com — Mon, 16 Mar 2009 16:24:23 GMT

Butte, Mont. – March 16, 2009 – At the first annual Montana BetterBricks Awards, three outstanding leaders in the green building industry were honored for their efforts by BetterBricks, the commercial initiative of the Northwest Energy Efficiency Alliance, along with NorthWestern Energy and the Montana Electric Cooperative Association (MECA). The winners were announced at the Montana Ambassadors Annual Conference, which was held in February at the Great Northern Hotel in Helena.

The BetterBricks Awards salute individuals pioneering high performance commercial buildings with an emphasis on energy efficiency in the Northwest. For this award, high performance buildings are commercial structures with a substantial level of energy savings as well as some or all of the following characteristics: incorporate day lighting with electrical lighting; reduce operating and maintenance costs; enhance productivity; consider local climate; support early design team decision-making; support commissioning. The result of these efforts: a greater number of buildings that offer improved energy efficiency and bottom line benefits.

The BetterBricks Awards also take place in three other Northwest cities: Portland, Seattle, and Boise. NorthWestern Energy and other Montana utilities encouraged BetterBricks to create a program for the Montana audience and helped facilitate the first annual Montana Awards.

Winners and finalists were selected in the following categories:

Owner/Decision Maker: Those who make decisions about strategic direction regarding investments in high performance buildings. These executives, developers, owners and managers support, authorize and generally enable high performance buildings to be built and operated.

Winner — Gary Griffith, Facilities Director (retired) Bozeman School District. Gary focused on energy conservation for the District, and through a combination of retrofits, repairs and operational practices, he dramatically decreased the District's natural gas consumption by 50 percent. Two of the District's elementary schools are believed to be the only ENERGY STAR ® certified schools in Montana, achieved under his direction.
Finalist — Tom Schussler, Director of Facilities, Providence St. Patrick Hospital and Health Sciences Center and Tim Chopp, Manager of Facilities Engineering, Providence St. Patrick Hospital and Health Sciences Center in Missoula. Because of Tom and Tim’s efforts, St. Patrick is the only hospital to certify (twice) under the ENERGY STAR program in the state of Montana.

Architecture: Those who design buildings and lead the design team on projects that consistently achieve high levels of energy efficiency in both new construction and major renovations.

Winner — Randy Hafer, President and co-owner of High Plains Architects in Billings. Randy led his team to reinvent a professional office building called, “Home on the Range.” This project received LEED® Platinum certification from the U.S. Green Building Council, currently Montana’s only Platinum project.

NorthWestern Energy Responds to Investigation Findings

web@northwestern.com — Fri, 13 Mar 2009 10:06:32 GMT

Butte , Mont. – March 13, 2009 – NorthWestern Energy has learned that investigators with the City of Bozeman Fire Department and the US Department of Alcohol, Tobacco and Firearms (ATF) have determined that a separation on a two-inch gas service line caused last Thursday’s explosion.

NorthWestern Energy officials have not yet had a chance to fully review the incident report, but they have been working in coordination with the investigation team. The company has brought in independent experts to help with its own investigation. The NorthWestern Energy service line in question has not yet been fully excavated and will be sent to a laboratory for further metallurgical testing to determine what caused the break.

Company investigators are seeking to understand all the evidence gathered to date including gas readings in the vicinity of the separation. However, the company has not examined the gas lines and appliances inside of the involved structures due to the recently completed fire investigation; it must now receive approval from property owners in order to gain access into the explosion site to finish its investigation.

"Our deepest sympathy goes out to the family and friends of Tara Bowman. Her loss will be felt throughout the Bozeman community. Our corporate family also wants others who were affected by the explosion to know you are in our thoughts and prayers. We will continue to work side-by-side with the affected businesses and the city of Bozeman to restore the downtown area to good economic health as soon as possible,” said Bob Rowe, President and CEO of NorthWestern Energy.

“We will continue to cooperate fully with the city, state and federal officials as they seek answers to a number of questions that still surround this terrible event. We will continue to examine the situation before the explosion and seek answers about why this occurred.”

The company is conducting a complete and thorough examination of the scene and the services in question to understand all of the contributing factors that may have led to this incident as part of ongoing system integrity activities. The additional testing is expected to take approximately three to six months, if all of the parties involved are able to cooperate.

NorthWestern Energy assures all our natural gas and electric customers that we are committed to ensuring the highest level of safety. The company strives to operate its electric and natural gas systems in compliance with all existing federal and state rules and regulations.

The company does annual leak inspection surveys and several other routine maintenance activities including corrosion control per DOT regulations in downtown commercial areas and along its major transmission pipelines. Residential areas are surveyed every five years, in accordance with DOT regulations.

Anyone who believes they smell natural gas should immediately leave the area and call NorthWestern Energy or 911 from a safe location. NorthWestern’s Gas Emergency number is 888-467-2427.

News Brief: NorthWestern Energy Details Explosion Response

web@northwestern.com — Tue, 10 Mar 2009 11:43:34 GMT

Butte, Mont. - March 10, 2009 - 12 p.m. — When disaster strikes, NorthWestern Energy mobilizes to secure electric and natural gas services that may be affected. An incident team is organized, comprised of front line responders, engineers, and others from throughout the company. The team is typically led on site, and remains together through a post-incident evaluation.

The recent explosion in downtown Bozeman is an example of what NorthWestern’s front line crews and other employees do to help ensure public safety. The following is a breakdown of the company’s response to this disaster.

The First 24 Hours
NorthWestern Energy electric and natural gas service employees were on the scene within minutes after the explosion. The company was asked to respond by the Bozeman Fire Department, which is standard procedure in any fire or emergency situation, but employees who felt and/or heard the blast were already en route to assist.

In any emergency situation, the scene is chaotic. This explosion blew out windows in the surrounding area. Shards of glass, splintered wood, brinks and mortar, roofing nails and building material was strewn around a two-block perimeter. Employees quickly coordinated with Bozeman Fire and Police to deenergize the electric service to the downtown area to help protect the safety of emergency workers fighting the fire, and assisted with the evacuation of residents and businesses in the immediate area.

As the linemen and engineers further assessed the situation and the area, they were able to narrow the scope of the electrical safety shutdown to restore electrical service to all but the most affected area, including turning on service to City Hall and emergency services located just blocks from the scene.

Gas service technicians shut off natural gas at the meters to buildings in the area that were most at risk of fire. This, too, is standard procedure in any emergency situation. Several natural gas service lines were damaged in the blast, and blowing natural gas created flames eight to ten feet high. The first priority was to help fire fighters secure the scene and provide whatever assistance they needed with immediate response.

NorthWestern Energy quickly assembled a team of employee-experts to help address the crisis, including those with experience in gas transmission operations and maintenance, pipeline safety, engineering, planning, supply procurement, communications and customer service. This team began reviewing maps and engineering plans to determine how best to isolate and stop the flow of natural gas to the damaged lines.

The company brought in employees from Butte and Deer Lodge to assist with the effort. Approximately a block west of the explosion, Bozeman Division employees exposed the buried 8” steel gas main located in the alley to reach a valve that had been installed in 2007. This valve enables a piece of equipment called a “stopper fitting” to be inserted that seals off the pipeline.

The “Westliners,” NorthWestern Energy’s highly specialized gas transmission response team based in Deer Lodge, began work east of the explosion to install another valve. The line is worked “hot” – in other words, pressurized gas is present in the line while it is being worked. The fitting is welded around the pipe, and then a “Mueller Tapping Machine” (the name of the piece of equipment) is attached which very slowly drills a hole in the top and bottom of the pipeline. Once the holes are drilled the stopper plug is inserted and the flow of gas is stopped.

This work began shortly after the crew arrived from Deer Lodge around 11 a.m. and the valve and fitting was finished around 5:30 p.m. that night. When pressure to the damaged gas line didn’t decrease as expected, the main was further excavated and another gas main, which ran perpendicular to this main, was found just east of the western-most valve. Crews determined that the best, and safest, approach was to install another stopper fitting on the alley main closer to the site of the explosion. That fitting was installed by 11:30 p.m. and by midnight that night the flow of gas was stopped.

Shortly after the initial response and once the area was evacuated, NorthWestern Energy employees working in coordination with Bozeman Fire began testing the ground (called pegging and bar holing) to look for gas leaks. They worked from the outside edge of the perimeters towards the center (the site of the explosion) looking for anything that might indicate the presence of a gas leak. They also inspected buildings and meters to ensure they were in good working condition and that there were no leaks.

By 7 p.m., although the flow of natural gas had not been stopped at the site of the explosion, Bozeman emergency officials determined that all but the immediately-affected area was safe, and allowed business owners and residents the opportunity to go into their property to secure the locations. By this time fire fighters had the fire contained, but used the flames to ensure that the blowing natural gas was safely consumed. Electric service crews were able to restore service to all but a handful of customers on the block.

After the Immediate Crisis
NorthWestern Energy employees remain on an incident scene long after the immediate crisis is over. In this case, NorthWestern linemen repaired and inspected explosion-damaged electric services, transformers, insulators, and line equipment, enabling electric service to be restored to all customers, except those businesses destroyed or severely damaged by the explosion by 2:30 a.m. the next morning.

Natural gas service technicians accompanied business/property owners as they entered their buildings to test for any potential problems and to relight their pilot lights. The company also continued to work on the natural gas main to place secure caps on the pipeline so that temporary, aboveground, services could be run to nearby businesses. This was critically important to those businesses that needed heat in order to reopen and to ensure that an approaching cold front didn’t result in broken water pipes and potentially more problems.

The installation of the caps also secured the services at the explosion site, enabling the investigation into the cause of the explosion to continue. Working in coordination with the Montana Public Service Commission and the US Department of Transportation (DOT) Pipeline Safety Administration, along with other investigating officials from US Department of Alcohol, Tobacco and Firearms (ATF) and Bozeman Fire, the company is assisting with tests of the main, service lines and meters and other equipment at the site. The company is cooperating fully and doing all it can to provide whatever information is needed by the investigating authorities.

NorthWestern Energy operates its electric and natural gas systems in compliance with all existing federal and state rules and regulations. The company does annual leak inspection surveys per DOT regulations in downtown commercial areas and along its major transmission pipelines. Residential areas are surveyed every five years, in accordance with DOT regulations. The company also runs advertisements and statement notices educating people on how to recognize the smell of natural gas and what to do if they smell natural gas. Property owners are responsible for the maintenance of natural gas lines from the meter onto their property.

Anyone who believes they smell natural gas should immediately leave the area (without turning on or off lights or picking up a telephone – which may spark an explosion) and call NorthWestern Energy or 911 from a safe location. Gas odor calls are assigned highest priority and are promptly responded to around the clock, seven days a week.

Moody's Investors Service Upgrades NorthWestern's Credit Ratings

web@northwestern.com — Tue, 10 Mar 2009 09:40:46 GMT

Sioux Falls, S.D. – March 10, 2009 – NorthWestern Corporation d/b/a NorthWestern Energy (NYSE: NWE) today announced that Moody’s Investors Service (Moody’s) has upgraded NorthWestern’s ratings.

	From	To
Senior Secured Rating	Baa2	Baa1
Senior Unsecured Rating	Baa3	Baa2
Outlook	Positive	Positive

Moody’s cited several reasons for the upgrade including the Company's 2008 financial performance, and the positive benefits of supportive rate case decisions in all three jurisdictions that addressed various operating cost pressures and utility infrastructure additions. Moody’s also acknowledged the fact that NorthWestern has essentially completed its goal of exiting all non-regulated business activities, following regulatory approval by the Montana Public Service Commission (MPSC) to place the company’s 30% ownership interest in the 740 megawatt coal-fired generation plant (Colstrip Unit 4) into utility rate base at a value of approximately $407 million.

NorthWestern is rated investment grade on all senior secured and unsecured debt with Moody’s, Standard and Poor’s Rating Group, and Fitch Investors Service.

“Achieving and maintaining strong credit ratings has been our goal because it is in the interest of our customers, investors and employees. It has also been a key objective of our regulators since the company emerged from bankruptcy, because they recognize the long-term benefits to customers,” said President and CEO Bob Rowe. “It is especially important in a time of market turbulence and instability, and will help us manage our investment commitments even better, and produce benefits to our customers through lower borrowing costs.”
