NorthWestern Energy Teams with Solution Mountain to Provide Community Economic Development Resources

web@northwestern.com — Mon, 11 Jun 2012 09:53:18 GMT

Huron, S.D. /Butte, Mont. – June 11, 2012 – In 2012,NorthWestern Energy (NWE) is expanding its economic development grant program offered in partnership with Solution Mountain, Inc. (SMI). Eligible applicants can apply for NWE grants valued at $5,000 each to assist both their business expansion and retention programs and their comprehensive economic development strategy programs. The grants are a 50/50 cash match for costs related to SMI’s community-building program.

NorthWestern Energy is also continuing its grant program to fund 100 percent of SMI’s economic impact studies (valued at $750 each). The studies are prepared on behalf of communities and local economic development organizations served by the utility.

In total, NorthWestern is offering 10 grants at $5,000 each (a 50 percent match) to fund the SMI business assessment and risk mitigation programs, and 25 grants valued at $750 each to pay 100 percent of impact analysis prepared by SMI. To qualify, applicants must be within the NWE service territory.

Ten Grants for Business Assessment and Risk Mitigation: The program includes an online business assessment that typically delivers the following:

A report of the community’s sales/employment trends and an analysis of how conditions compare to periods prior to the 2008 economic downturn
A report of local businesses with ‘critical business needs’
Creation of a local ‘stakeholder’ team to help mitigate critical business needs
A list of potential growth candidates for an economic gardening program
A leakage report that shows how well local industries are retaining dollars as compared to surrounding counties

Where applicable, SMI will format the information gathered from the local business assessment for easy uploading into existing business retention programs.

Twenty Five Grants for Economic Impact Studies: The grant program is to assist communities and economic development organizations that need to value the economic impact(s) of projects that either exist or are proposed. SMI uses proprietary software to measure the economic “footprint” of projects. The reports help to predict how revenue and expense dollars multiply within a community and how their benefits impact both direct and indirect jobs.

NorthWestern Energy Submits Annual Electricity and Natural Gas Supply Cost Filings to Montana PSC

web@northwestern.com — Fri, 08 Jun 2012 14:40:25 GMT

Butte, Mont. – June 8, 2012 – NorthWestern Energy has submitted its annual electricity and natural gas supply cost tracker filings to the Montana Public Service Commission.

Supply costs are adjusted on a monthly basis based on actual costs and forward projections, but on an annual basis, these supply costs are evaluated in a formal regulatory process.

The filings include costs for energy purchased from market sources as well as rate-based resources owned by NorthWestern Energy. The requested natural gas supply cost for the month of July is $0.39 per therm compared to $0.51 for the same period last year. The requested electricity supply cost for the month of July is $0.06 per kilowatt hour (kWh), which is basically unchanged from the same period a year ago. The electric supply tracker includes a requested adjustment to reflect under-collected supply costs. The proposed rate increase would be $.001/kWh or one-tenth of one cent.

Typical natural gas customers use 100 therms per month, while typical electricity customers use 750 kWh per month. Supply rates are just one component of the total bill, and customers are encouraged to regularly review their bill to determine their actual usage as compared to the typical average.

The filings, including supporting documents, are posted on our website. Please visit www.northwesternenergy.com and enter the search term “2012 tracker” to find the information.

NorthWestern Energy Encourages Customers to Include Efficiency in Summer Projects

web@northwestern.com — Wed, 06 Jun 2012 15:47:32 GMT

Butte, Mont. – June 6, 2012 – Montana weather can be unpredictable as these past weeks have demonstrated. NorthWestern Energy is suggesting that its home- and water-heating customers do a few things to prepare their homes for this next heating season.

First, is to schedule a free energy audit on their home to find out how to better manage this winter's heating costs. Second, customers are encouraged to take action on the recommendations from the audit before winter returns.

“The easiest and cheapest way to save energy is to become aware of what you're using it for," said Bill Thomas, NorthWestern Energy's Manager - Regulatory Support Services. "With the E+ Audit for the home, our space and water heating customers receive information customized to their home and their lifestyle that helps them make choices that can reduce the amount of energy they use.”

“Customers find that the audit helps them focus their energy saving efforts on the most cost-effective measures. It also makes them more aware of how energy efficiency can be incorporated into home remodeling and additions," added Thomas. Insulation in the attic, crawl space and/or basement walls are frequently the major measures recommended in an audit and rebates may be available. Savings from these measures in comparison to costs to install them usually add up quickly. Other audit recommendations may focus on customer behaviors to save energy.

A pair of energy conservation specialists from KEMA, NorthWestern Energy's audit contractor, arrives at the customer's home at the scheduled time and get right to the task. They take measurements of the home, its windows and doors, and insulation levels. Customers answer questions about how they use energy, what appliances are used and how often. A blower-door test identifies where air leaks are and whether or not the home is too drafty. Conversely, the test may indicate that additional outside air is needed to improve the health and safety of occupants. When appropriate, the heating system receives an operational and safety check, the water heater is wrapped with an insulating blanket to keep heat in, and low-flow showerheads and faucet aerators are installed.

Within a couple weeks of the audit, the customer receives the E+ Audit report for their home with charts showing how much of their energy dollar is going to various uses in the home. This includes heating, lights, air conditioning or laundry based upon the customer's responses to questions in the audit.

The E+ Audit for the home is available to NorthWestern Energy customers who heat their home with electricity or natural gas delivered by NorthWestern Energy. Other qualifications apply. To find out if your home qualifies, call 1-800-823-5995. If your home has been previously audited under the E+ Audit program, call for a copy of the audit report so that you can take the recommended actions before the weather drops next winter.

NorthWestern Energy offers the E+ Energy Appraisal for Small Businesses to its small commercial electric customers and provides an E+ Energy Survey by mail to its residential electric customers who heat their home and hot water with energy that is not delivered by NorthWestern Energy. Find out more about NorthWestern Energy's E+ programs and rebates for homes and businesses by visiting www.northwesternenergy.com/eplus.

NorthWestern Energy Wellness Program Brings Home the Gold

web@northwestern.com — Mon, 04 Jun 2012 08:37:51 GMT

Butte, Mont. – June 4, 2012 – NorthWestern Energy learned recently that the company’s Energize Your Life wellness program received the highest award possible from the Montana Worksite Health Promotion Coalition for excellence in promoting worksite health.

The coalition evaluated NorthWestern’s wellness program, which began in 2011, on ten criteria ranging from management commitment to measured outcomes. “It is unusual for a company’s wellness program to attain this achievement within its first year and speaks highly of our commitment to promoting employee wellness,” explained Peggy Lowney, NorthWestern Energy’s director of compensation and benefits.

NorthWestern received the award at the Worksite Health Promotion Conference in Helena on May 2 -3. The Montana Worksite Health Promotion Coalition created the bronze, silver and gold awards to recognize Montana employers who offer basic, enhanced or comprehensive worksite wellness programs. Every two years, participants submit detailed documentation describing implementation of their programs, and a team of wellness professionals judges the entries.

In addition to the gold award, Tabatha Elsberry, manager for NorthWestern Energy’s wellness program, received the Jill Young Award in recognition of outstanding wellness performance.

In March 2011, NorthWestern Energy officially began its Energize Your Life wellness program. However, significant preparation was necessary before that date. “We had commitment from the executive team and board of directors but we were starting from scratch,” Lowney said. “We needed to develop a very structured plan that could be applied to 1,400 employees and their family members in several towns across three states. Our plan calls for company provided annual health screenings and health risk assessments along with numerous programs or opportunities for employees to make healthy lifestyle choices.”

Lowney added that employees who voluntarily take steps to improve and maintain their own personal health can receive additional employer contributions toward the premiums they pay for their company-provided health insurance. “Wellness goals are unique to each individual and employees who set and achieve even incremental goals are rewarded – with better personal health and reduced premium payments. Everyone wins.”

Wellness programs are designed to maintain or improve employee health before problems arise. Workplace wellness programs encourage people to take steps to prevent the onset or worsening of a health condition and to adopt healthier lifestyles. Businesses may implement many types of workplace wellness programs, from onsite gyms to simple workplace wellness newsletters. NorthWestern Energy chose to institute a very comprehensive workplace wellness program.

“We believe that encouraging our employees to improve and maintain their own good health is one of the best investments we can make,” added Kendall Kliewer, NorthWestern’s vice president and controller with responsibility for employee benefits. “Promoting wellness at work can substantially reduce health care costs, absenteeism and workers compensation costs, which benefits employees, their families and NorthWestern.”

NorthWestern Energy Launches Community Works

web@northwestern.com — Thu, 26 Apr 2012 10:56:37 GMT

Butte, Mont. – April 25, 2012 – NorthWestern Energy’s tradition of funding community activities, charitable efforts and economic development within its three-state utility service territory now has a new name and expanded focus.

In celebration of its 2012 Centennial, NorthWestern is bringing together its charitable contributions, economic development and community sponsorship programs under the name Community Works and is providing $100,000 in additional funding for college scholarships.

“We’re celebrating our first century and building for our second, which will require a workforce of highly skilled, knowledgeable employees in a variety of disciplines - including math, science, engineering and the technical skills needed for the electricity and natural gas industry,” said Bob Rowe, President and CEO. “Many of our prospective employees come from our local technical colleges and universities so we’re looking at our new scholarship program to provide not only needed assistance with the cost of education but also to build long-term relationships with these students as they transition into their careers.”

Rowe added, “We believe the name Community Works reflects the grassroots nature of our company’s charitable activities that are driven mostly by local organizations and volunteer efforts. It also depicts the close connection and coordination between NorthWestern Energy and the communities we serve.”

The scholarships will be in various amounts and target specific areas of focus that reflect NorthWestern Energy’s expectations of its future workforce needs; however, the company will not administer the scholarships nor choose the recipients. NorthWestern Energy has identified the educational institutions in Montana, South Dakota and Nebraska that it plans to work with on this effort, but hasn’t yet finalized the details with all of the corresponding institutions. However, the company has announced that $20,000 in scholarships will be made available to students attending Montana Tech of the University of Montana this autumn.

NorthWestern Energy’s Community Works programs currently provide more than $1.5 million in funds for community sponsorships, charitable contributions and economic development organizations in Montana, South Dakota and Nebraska. More information about grant requests is available on the company’s website at www.northwesternenergy.com.

Forbes Names NorthWestern Energy One of America's Most Trustworthy Companies

web@northwestern.com — Wed, 25 Apr 2012 14:14:49 GMT

Sioux Falls, S. D. – April 25, 2012 – Forbes has recognized NorthWestern Corporation d/b/a NorthWestern Energy (NYSE: NWE) as one of America’s Most Trustworthy Companies for the second time.

“We’re proud to be named as one of the 100 Most Trustworthy Companies in the country because it means that we’re doing many of the right things,” said Bob Rowe, President and CEO. “Companies that make this list don’t have problems that indicate elevated risk. NorthWestern Energy has consistently demonstrated transparent and conservative accounting practices, solid corporate governance and management.”

The announcement came as NorthWestern Energy’s shareholders overwhelming approved proposals to elect each of the directors to another annual term on the board and the company’s executive compensation pay structure.

The last few years have seen their share of corporate scandals, bailouts and bankruptcies. Forbes set out to identify the most transparent and trustworthy businesses that trade on American exchanges. Forbes uses an independent financial analytics company, GMIRATINGS, to conduct quantitative and qualitative analysis that looks beyond the raw data on companies’ income statements and balance sheets to assess the true quality of corporate accounting and management practices.

GMI’s 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. The absence of negative events counts as much as the existence of positive events.

To create the list, GMI examines more than 8,000 companies traded on U.S. exchanges and assigns an accounting and governance risk score (AGR) quarterly to each company based on a proprietary modeling methodology.

To qualify for the roster, the 100 companies (segmented by market size) all had to have market caps of $250 million or more at the time the list was prepared (March 31, 2012). Over the last four quarters, the companies must have maintained conservative or average AGR ratings, and had no amended filings with the Securities and Exchange Commission, no SEC enforcement actions, and no material restatements. They also had to rank high in GMI’s Equity Risk Ranking, which indicates a positive forecast for equity returns, and have minimal likelihood of financial distress as measured by GMI.

According to GMI, studies show that well-governed companies with transparent accounting have a higher price premium than their competitors, reduced cost of capital, and a higher long-term return for shareholders.

NorthWestern was also recently recognized by Glass Lewis, a leading investment research and global proxy advisory firm, as one of the top 42 companies in the US for its 2011 “Say on Pay” proposals. Although the rules require a shareholder vote once every three years, NorthWestern Energy’s Board of Directors places the issue before shareholder annually. Glass Lewis recognized the 42 companies both for the quality of the compensation disclosures in their proxy statements and for the structure of their executive compensation programs. The Glass Lewis study was based on a review of almost 1,700 2011 corporate proxy statements.

NorthWestern Energy Asks Montana Public Service Commission to Place Natural Gas Production Field into Rate Base

web@northwestern.com — Tue, 03 Apr 2012 15:16:13 GMT

Butte, Mont. – April 3, 2012 – NorthWestern Corporation d/b/a NorthWestern Energy (NYSE:NWE) has filed an application with the Montana Public Service Commission to place the company’s Battle Creek natural gas assets into rate base.

NorthWestern Energy purchased the proven production field and gathering system in 2010 for $12.4 million as part of an overall strategy to provide rate stability and customer value through the addition of regulated assets that are not subject to market forces. Montana Power owned about fifty percent of the natural gas used by its customers, with the price based on the cost of providing the gas. These gas resources were sold as part of supply deregulation. Since then, the transmission and distribution prices have been set on the regulated cost of providing the service, while the price of gas has been based on short-term market purchases.

Although Battle Creek provides less than 3-percent of the company’s total natural gas requirements, the field’s anticipated 47-year life span appropriately contrasts with the industry’s 1-3 year contract period at market rates.

There is no immediate rate impact associated with this filing since revenue is already being collected in rates through the natural gas tracker. However, the filing is necessary to formalize the cost of service components associated with the field and the approval of a stipulation with Montana Consumer Counsel (MCC) on the cost of capital. NorthWestern is requesting a return on equity of 10.00% and a debt-to-equity structure of 52/48.

NorthWestern Energy provides electricity and natural gas in the Upper Midwest and Northwest, serving approximately 668,300 customers in Montana, South Dakota and Nebraska. More information on NorthWestern Energy is available on the company's website at www.northwesternenergy.com.

NorthWestern Energy Updates Winter Storm Restoration

web@northwestern.com — Wed, 21 Mar 2012 10:54:42 GMT

Butte, Mont. – March 21, 2012 – NorthWestern Energy crews are still working to restore power to rural customers in northern Montana.

Outages continue in rural areas in the Havre, Lohman, Chinook, Zurich, Harlem and Fort Belknap areas. NorthWestern Energy crews have been called in from across the state and are working on downed power lines in these areas. Power is expected to be restored to most homes by the end of the day on Wednesday with complete restoration expected by tomorrow.

Please watch for utility crews working with trucks and equipment alongside Highway 2 and other secondary highways and county roads, and drive with caution when passing work sites. Stay away from low-hanging and downed power lines. Consider them potentially energized and dangerous and call us to report burning, arcing or sparking wires and poles at 888-467-2669.

In the meantime, NorthWestern reminds comers to stay safe during the storm.

Natural Gas Customers

Heavy wet, blowing snow can block heating and appliance exhaust vents which can cause equipment to malfunction resulting in a loss of heat or a buildup of deadly carbon monoxide in the structure.

Outdoor natural gas meters and equipment are designed to withstand Montana’s winter weather conditions. However, heavy buildup of snow or ice, icicles falling from building eaves, or water dripping from a roof and freezing on a natural gas meter or appliance vent, may disrupt the flow of natural gas or create a potentially dangerous situation inside the structure.

It at any time if you smell a strong and persistent odor similar to sulfur or rotten eggs, leave your home immediately and avoid using any electric appliances such as light switches, garage door openers and phones—including a cell phone. When you are at a safe distance away, call NorthWestern Energy at (888) 467-2669 or 911 to report the concern. Stay away from the building until someone from the utility or a first responder tells you it’s safe.
Unlike natural gas, carbon monoxide is odorless and may be present when a fuel is not burned completely due to inadequate combustion air or when exhaust vents become clogged. Carbon monoxide symptoms include headache, nausea, vomiting, fatigue, and confusion. If you suspect carbon monoxide may be present, seek fresh air immediately and call NorthWestern Energy.

Other safety reminders include:

Ensure your natural gas meter is visible at all times and accessible for maintenance and emergency responders.
Avoid using a snow blower near a meter to keep from burying the meter with snow.
Gently remove the snow or ice around the meter with your hands or use a broom to brush it away. If ice or excessive snow has encased your meter, contact NorthWestern Energy at (888) 467-2669.
Never kick or hit your natural gas meter or its piping with a hammer or other hard object in order to dislodge snow or ice.
Keep natural gas vents clear, unobstructed and free of debris. Some direct-vent and high-efficiency appliances have direct side wall outdoor vents and air intakes that could become obstructed during heavy snowfall. Other vents may be on the roof.
If you have a seasonal property or are away on vacation, ask someone to check your natural gas meters and vents—especially after a significant storm. A covered meter, in addition to being potentially dangerous, can disrupt service leading to loss of heat to the structure.

Electric Customers

Customers calling to report outages may experience extended on-hold times in the event of a large-scale outage situation. Customers who wish to report an outage and don’t want to wait to speak to a representative can leave a message by following the prompts within the telephone system.

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 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 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, lights and unplug sensitive electronic equipment. Using a surge protector also helps to protect sensitive electronic equipment such as televisions and computers.

NorthWestern Energy Green Lights Spion Kop Wind Project

web@northwestern.com — Tue, 20 Mar 2012 15:36:24 GMT

Butte, Mont. – March 20, 2012 – NorthWestern Corporation d/b/a NorthWestern Energy (NYSE: NWE) has issued a Notice to Proceed to Compass Wind to move forward with construction on the 40-megawatt Spion Kop Wind Project near the central Montana community of Geyser.

The Montana Public Service Commission approved placement of the $86.1 million project into the company’s regulated rate base in mid-February. Both the energy and associated renewable energy credits will be used to meet the renewable portfolio standards obligations in Montana law.

“We’re pleased to be moving forward on the project so that we can meet our 2015 renewable portfolio standards obligation while maintaining a balanced, environmentally responsible portfolio of generation resources that contributes to long-term rate stability,” said Bob Rowe, president and CEO.

Under Montana’s Renewable Portfolio Standards (RPS), 15-percent of NorthWestern Energy’s total energy portfolio must be produced from renewable generation by 2015. While the RPS goals are important, it is the project’s contribution to the local area that has Judith Basin County officials excited.

“It’s a great project and will be of great benefit to the county,” said Cody McDonald, chairman of Judith Basin County Commission. “Compass Wind has been really good to work with and we’ve received nothing but positive feedback from our local constituents about this project.”

The Spion Kop Wind Project will include 25 1.6 megawatt GE wind turbines near Geyser, Montana. Construction is set to begin later this spring, and the project is due to be completed by the end of the year.

About NorthWestern Energy
NorthWestern Energy provides electricity and natural gas in the Upper Midwest and Northwest, serving approximately 668,300 customers in Montana, South Dakota and Nebraska. More information on NorthWestern Energy is available on the company's website at www.northwesternenergy.com.

NorthWestern Energy Updates Winter Storm Restoration in Northern Montana

web@northwestern.com — Tue, 20 Mar 2012 14:55:30 GMT

Butte, Mont. – March 20, 2012 – NorthWestern Energy crews are still working to restore power to about 500 customers in northern Montana.

While power was restored to Chinook early this morning, crews will have to take the community out of power again later this afternoon (around 4 or 5 p.m.) to complete substation repairs. Once that repair is complete service will be restored to Chinook and Lohman. NorthWestern anticipates that outages in Zurich, Harlem, and outlying rural areas will continue into tomorrow.

NorthWestern Energy currently has 11 internal and contract crews working to restore power in the area from Havre, Great Falls and Lewistown.

In the meantime, NorthWestern reminds comers to stay safe during the storm.

Natural Gas Customers

Heavy wet, blowing snow can block heating and appliance exhaust vents which can cause equipment to malfunction resulting in a loss of heat or a buildup of deadly carbon monoxide in the structure.

Other safety reminders include:

Ensure your natural gas meter is visible at all times and accessible for maintenance and emergency responders.
Avoid using a snow blower near a meter to keep from burying the meter with snow.
Gently remove the snow or ice around the meter with your hands or use a broom to brush it away. If ice or excessive snow has encased your meter, contact NorthWestern Energy at (888) 467-2669.
Never kick or hit your natural gas meter or its piping with a hammer or other hard object in order to dislodge snow or ice.
Keep natural gas vents clear, unobstructed and free of debris. Some direct-vent and high-efficiency appliances have direct side wall outdoor vents and air intakes that could become obstructed during heavy snowfall. Other vents may be on the roof.

Butte, Mont. – Mar. 19, 2012 – A major spring snow storm affecting a large swath of Montana prompts NorthWestern Energy to remind customers of important safety measures.

NorthWestern Energy is currently reporting widespread outages along Montana’s Hi-Line and through central Montana due to heavy wet snow.

“The role of corporations in public discourse is extremely important to many people right now,” said Bob Rowe, president and CEO. ”We have adopted a formal political contributions policy so our customers and shareholders may see clearly and understand how we use our resources to advance matters of public policy that are consistent with our values, our legal obligations and our Code of Conduct.”

NorthWestern Selects MS Chapters as 2012 Corporate Volunteer Partner

web@northwestern.com — Mon, 13 Feb 2012 11:39:16 GMT

Butte, Mont. – Feb. 13, 2012 – NorthWestern Energy announced recently that its employees have selected the Montana, Nebraska and South Dakota chapters of the National Multiple Sclerosis (MS) Society as the company’s Corporate Volunteer Partner for 2012.

Through this partnership, the MS chapters will receive $25,000 to help them underwrite their Walk MS and Bike MS fundraising events within NorthWestern Energy’s service territory, as well as being a focus for local volunteer activity. The purpose of the National MS Society Chapters is to provide assistance, information and inspiration to individuals affected by multiple sclerosis; to host fundraising events; and to fund cutting-edge research into treatments and a cure.

“We were very pleased with both the number and quality of the applications we received for this annual grant,” said Bob Rowe, NorthWestern Energy President and CEO. “It was a difficult decision for our charitable contributions committee to make. Working with the National MS Society Chapters allows us to support an important nonprofit organization with a presence in our three states while providing opportunities for local events in which our employees may volunteer.”

Since 2007, NorthWestern Energy has donated approximately $3 million through its Charitable Giving Program to qualified nonprofit organizations operating within the utility’s three-state service territory. NorthWestern works with charitable nonprofit organizations to provide fundraising and volunteer opportunities for NorthWestern’s almost 1,400 employees throughout Montana, South Dakota and Nebraska. Local employee committees organize almost all of NorthWestern’s charitable activities. In 2009, NorthWestern began providing additional support to a company-wide charitable partner also selected by a committee of employees.

“2012 is a special year for us,” Rowe said. “We are commemorating a century of service so are planning special events that not only celebrate our first century but also help us build for the second. Organizations like the National MS Society Chapters support this concept by making our communities better places to live for everyone and give those with MS hope for the future.”

Previous corporate partners include the March of Dimes’ Walk for Babies, the American Cancer Society’s Relay for Life, and Special Olympics. Partner organizations receive a $25,000 donation from NorthWestern Energy and employee events throughout the year typically raise an additional $25-30,000.

About multiple sclerosis
Multiple sclerosis interrupts the flow of information between the brain and the body and stops people from moving. Every hour in the United States, someone is diagnosed with MS — an unpredictable, often disabling disease of the central nervous system. Symptoms range from numbness and tingling to blindness and paralysis. The progress, severity and specific symptoms of MS in any one person cannot yet be predicted, but advances in research and treatment are moving us closer to an MS-free world. Most people with MS are diagnosed between the ages of 20 and 50, with more than twice as many women as men affected by the disease. More than 400,000 people in the United States and 2.5 million worldwide live with MS.

About the National Multiple Sclerosis Society, Greater Northwest Chapter
MS stops people from moving. The National MS Society exists to make sure it doesn’t. The Society addresses the challenges of each person affected by MS by funding cutting-edge research, driving change through advocacy, facilitating professional education, collaborating with MS organizations around the world, and providing programs and services designed to help people with MS and their families move their lives forward. Headquartered in Seattle with offices in Anchorage and Billings, the Greater Northwest Chapter serves over 12,000 people living with MS and more than 72,000 others including family, friends, caregivers and health care professionals in Alaska, Montana, and Central and Western Washington. We are people who want to do something about MS now. Join the Movement® at MSnorthwest.org.

NorthWestern Energy Announces Outage of Generating Station

web@northwestern.com — Thu, 02 Feb 2012 17:10:56 GMT

Butte , Mont. – Feb. 2, 2012 – NorthWestern Corporation d/b/a NorthWestern Energy (NYSE:NWE) announced today that its Dave Gates Generating Station will be down for a period of up to several months following the discovery of a problem within the gas turbines on each of the three generation units.

One of the 50-megawatt units was taken off-line in mid-January due to a vibration alarm. One of the turbines has been removed and sent back to the manufacturer, Pratt & Whitney, for repair. Inspections of the other two units, each of which is fitted with two gas turbines, indicated similar concerns. Although functional at the time, NorthWestern took the remaining units out of service this week to prevent further damage. The turbines, which are under warranty, will be removed and repaired. The plant had a full year of successfully keeping the Montana electric network in balance and operating reliably, as loads on the system and resources available to meet those loads continually move up and down.

“We’re concerned about this situation and focused on it. However, we are pleased that the problem was identified promptly and is being addressed. We are working closely with the manufacturer and NAES, the plant’s operator, to get the plant back up and running at full capacity as soon as it’s safe to do so and to do all of the necessary analysis to prevent this situation from reoccurring in the future,” said Bob Rowe, President and CEO.

NorthWestern plans to resume production on each unit as the turbines are inspected, reinstalled, and tested with the first unit back in production perhaps within 45 days. The plant is anticipated to resume full production within 90 – 180 days, barring any unforeseen circumstances.

In the meantime, NorthWestern has entered into contracts with third parties for replacement regulation service and the appropriate filings have been made with the Federal Energy Regulatory Commission (FERC) for these agreements. These agreements will enable the company to provide the necessary services to maintain reliability of its transmission system. The incremental costs associated with the shutdown will be addressed through the normal course of business.

The Dave Gates Generating Station at Mill Creek is located east of Anaconda, Mont., and provides regulating reserve service to maintain transmission reliability within NorthWestern Energy’s control area. It was placed into commercial operation on January 1, 2011, and consists of three 50-megawatt natural gas fired units—two of which act as primary units and the third serves as an operational spare.

NorthWestern Energy Issues Power Line Safety Reminder

web@northwestern.com — Wed, 25 Jan 2012 15:20:49 GMT

Butte, Mont. – Jan. 25, 2012 – Very high winds are battering parts of Montana prompting NorthWestern Energy to remind customers to be on the lookout for downed or low-hanging power lines.

As of midday, NorthWestern Energy is reporting dozens of scattered outages, mostly in central and north central Montana as strong, gusty winds push through the area. Customers calling to report outages may experience extended on-hold times in the event of a large-scale outage situation.

Customers who wish to report an outage but who don’t want to wait on hold to speak to a representative can leave a message by following the prompts within the telephone system.

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.
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, lights and unplug sensitive electronic equipment. Using a surge protector also helps to protect sensitive electronic equipment such as televisions and computers.

NorthWestern Energy Issues Safety Reminder for Natural Gas Customers

web@northwestern.com — Thu, 19 Jan 2012 09:17:13 GMT

Butte, Mont. – Jan. 19, 2012 – As many Montana communities continue digging out from a heavy winter snow storm, NorthWestern Energy is cautioning natural gas customers to pay special attention to appliance exhaust vents and outside meters.
NorthWestern’s gas servicemen have been busy overnight and this morning responding to “no-heat” calls caused by blocked appliance vents. In addition to a loss of heat, blocked appliance vents could cause a buildup of deadly carbon monoxide in the structure.

Outdoor natural gas meters and equipment are designed to withstand Montana’s winter weather conditions. However, heavy buildup of snow or ice, icicles falling from building eaves, or water dripping from a roof and freezing on a natural gas meter or appliance vent, may disrupt the flow of natural gas or create a potentially dangerous situation inside the structure.

If your home has an outside natural gas meter, check it routinely for accumulation of ice or snow. Look for your natural gas appliance vents – which often are on the roof – to ensure they are clear of snow. Also remember that clearing snow and ice from meters or vents needs to be done carefully and gently to avoid damaging the equipment.

It at any time if you smell a strong and persistent odor similar to sulfur or rotten eggs, leave your home immediately and absolutely avoid using any electric appliances such as light switches, garage door openers and phones—including a cell phone. When you are at a safe distance, call NorthWestern Energy at (888) 467-2669 or 911 to report the concern. Stay away from the building until someone from the utility or a first responder tells you it’s safe.

Unlike natural gas, carbon monoxide is odorless and may be present when a fuel is not burned completely due to inadequate combustion air or when exhaust vents become clogged. Carbon monoxide symptoms include headache, nausea, vomiting, fatigue, and confusion. If you suspect carbon monoxide may be present, seek fresh air immediately and call NorthWestern Energy.

Other safety reminders include:

Ensure your natural gas meter is visible at all times and accessible for maintenance and emergency responders.
Avoid using a snow blower near a meter to keep from burying the meter with snow.
Gently remove the snow or ice around the meter with your hands or use a broom to brush it away. If ice or excessive snow has encased your meter, contact NorthWestern Energy at (888) 467-2669.
Never kick or hit your natural gas meter or its piping with a hammer or other hard object to dislodge snow or ice.
Keep natural gas vents clear, unobstructed and free of debris. Some direct-vent and high-efficiency appliances have direct side wall outdoor vents and air intakes that could become obstructed during heavy snowfall. Other vents may be on the roof.
If you have a seasonal property or are away on vacation, ask someone to check your natural gas meters and vents—especially after a significant storm. A covered meter, in addition to being potentially dangerous, can disrupt service leading to loss of heat to the structure.

NorthWestern and BPA Agree to Discuss Ways to Collaborate on MSTI Project

web@northwestern.com — Wed, 11 Jan 2012 07:33:27 GMT

Butte, Mont. – Jan. 11, 2012 – NorthWestern Energy (NYSE:NWE) and the Bonneville Power Administration (BPA) have agreed to explore collaboration on the Mountain States Transmission Intertie (MSTI) project. The line would allow the transfer of renewable and other energy sources from Montana, Idaho and other regional markets, and could allow BPA to serve customers in Idaho, western Wyoming and Montana and provide other operational benefits.

“We look forward to working with BPA on the MSTI project to determine how it might be of benefit to BPA in serving its customers in Idaho, Wyoming and Montana,” said NorthWestern Energy Vice President of Transmission Mike Cashell.

BPA has current and future requirements to serve customers in Idaho, western Wyoming, and southern Montana. BPA currently serves these customers through agreements with PacifiCorp using the South Idaho Exchange Agreement and PacifiCorp General Transfer Agreement. Because the South Idaho Exchange Agreement will terminate in 2016, BPA is evaluating various alternatives to serve its customers affected by the termination.

“This is a great example of regional transmission planning and coordination,” said Brian Silverstein, senior vice president, BPA Transmission Services. “Participation in the MSTI project could help us with our requirement to serve our customers in and around southeastern Idaho and provide other benefits. We are eager to see what BPA might gain from being part of this project.”

This week, NorthWestern and BPA signed a Memorandum of Understanding (MOU) agreeing to explore the potential of a MSTI Project that would accommodate both parties' needs. The MOU stipulates that by July 31, 2012, the parties seek to complete economic and engineering viability studies and a capacity and cost allocation methodology that considers other partners in the line and treatment for unsubscribed capacity and cost. The outcome of these studies will provide information necessary for BPA to determine whether or not to consider future agreements for participation in the MSTI project.

NorthWestern started environmental review of the 500-kilovolt project in summer 2008. The proposed line would extend from a new proposed substation five miles south of Townsend, Mont., to Idaho Power Company’s existing Midpoint Substation near Jerome, Idaho. NorthWestern Energy anticipates the draft Environmental Impact Statement will be issued in mid-2012. NorthWestern also is planning to conduct an Open Season that will provide utilities, independent power producers and other interested parties an opportunity to subscribe capacity on the MSTI line. NorthWestern anticipates energizing the line in 2016. Additional information about the MSTI project is available at http://www.msti500kv.com.

NorthWestern Energy Submits Montana Electric Supply Plan

web@northwestern.com — Fri, 16 Dec 2011 08:00:15 GMT

Butte, Mont.. – Dec. 16, 2011 – NorthWestern Corporation d/b/a NorthWestern Energy (NYSE: NWE), has submitted to the Montana Public Service Commission its biennial Electricity Supply Resource Procurement Plan that discusses some of the short- and long-term steps to maintain and acquire reliable, cost-effective energy resources for customers.

A balanced approach to portfolio management is reflected in the 2011 Plan where stakeholders are informed about the analytical methods, supporting information, and the conclusions derived from long-term planning work. Changing conditions and future uncertainty have caused NorthWestern to review earlier planning assumptions and work in each of its long-term planning cycles that are updated every two years. It has adjusted resource acquisition planning to properly reflect current and forecast conditions, including market forecasts, to ascertain options and actions available to NorthWestern and to retail customers.

NorthWestern is pursuing the orderly rebuilding of a vertically integrated electric utility through asset development and/or purchase as authorized under the Electric Utility Industry Generation Reintegration Act (Section 69-8-101 through 69-8-426, MCA). Owned assets would provide cost-effective generating resources that would allow customers, regulators, and NorthWestern to exercise greater control over future long-term energy costs while assuring reliable delivery at known and predictable rates. NorthWestern is looking for opportunities to cost-effectively integrate new owned electric generation resources into the Electricity Supply Resource Portfolio to achieve long-term stable rates for customers.

NorthWestern’s three year action plan contains specific measures and steps showing how NorthWestern intends to move forward and put into “action” the steps it has defined in order to meet resource needs and maintain reliable, cost-effective electricity supply resources. Three year action plan steps are a combination of the following initiatives and ongoing activities:

Identify, consider, and procure, if available, electric generation assets that meet acceptable levels of portfolio energy, cost, and risk;
Replace the existing electricity supply contracts (including the volumes associated with the PPL 7-year agreement) set to expire in the 2012-2014 timeframe with new, 3- to 5- year staged market-based supply contracts and/or utility owned generation assets;
Refine analysis associated with gas-fired generation technology including the evaluation of costs, resource flexibility, and portfolio needs;
Evaluate options to define resource adequacy standards including specific resource attributes and load serving capabilities;
Improve the strategies and methods associated with integrating intermittent resources including wind power;
Meet Renewable Portfolio Standards (RPS) consistent with Montana statutes;
Add new electric supply resources to the portfolio (including Spion Kop and QFs);
Acquire cost-effective Demand Side Management (DSM).
NorthWestern has prepared and submitted biennial plans since 2003. The plan is intended to be a guide to inform the PSC and customers of the decision making process, rationale and vision developed by NorthWestern and its advisors to secure supply resources.

The 2011 Electricity Supply Resource Procurement Plan is available by visiting www.northwesternenergy.com.

NorthWestern Energy Recognized for 2011 Projects of the Year Award

web@northwestern.com — Tue, 13 Dec 2011 14:13:12 GMT

Butte, Mont. – Dec. 13, 2011 – NorthWestern Energy’s Dave Gates Generating Station at Mill Creek (DGGS) was recognized by Power Engineering at the 2011 Projects of the Year Awards.

Power Engineering magazine is the voice of the power generation industry. The Projects of the Year Award recognizes exceptional power generation projects around the world that were completed in the past year and congratulates companies for being instrumental in meeting the growing demand for energy.

This year’s Projects of the Year Award winners and honorable mentions represented facilities and/or technology that signified excellence in three categories: coal-fired, gas-fired and renewable energy. The DGGS was one of two honorable mentions in the gas-fired category. The DGGS is believed to be the first gas-fired project of its kind built solely to integrate variable generation resources into NorthWestern Energy’s transmission system. The plant balances load and generation on a moment-to-moment basis to maintain transmission system reliability for NorthWestern Energy’s customers.

The DGGS is a 150-megawatt, natural gas fired generating unit, which began commercial operation on January 1, 2011. At peak construction, there were 265 workers onsite with a total payroll of approximately $20 million. The approximate $185 million facility operates 24-7 and was built on time and under budget. NorthWestern’s third-party operator, NAES Corp., operates and maintains the plant.

NorthWestern Energy Settles Natural Gas Rate Case with South Dakota Public Utility Commission

web@northwestern.com — Tue, 22 Nov 2011 15:01:00 GMT

Huron, S.D. – Nov. 22, 2011 – NorthWestern Energy (NYSE: NWE) announced today that the South Dakota Public Utility Commission has approved a stipulated agreement to settle the company’s natural gas rate case.

As a result of the settlement, NorthWestern Energy will increase rates by approximately $1.8 million annually beginning December 1. Customers using 100 therms of natural gas per month will see their bills increase by $4.37 or about 4.9%. Customers are encouraged to read the insert in their December bill about the rate increase which includes a breakdown of potential impact depending on usage ranging from 10 to 500 therms per month.

The $1.8 million annual increase is comprised of about $1.5 million annually for an increase due to higher operating and maintenance costs related to the natural gas system in South Dakota and about $.3 million annually for the company’s ongoing remediation of manufactured gas plant (“MGP”) sites in the state. The original request included a $1.4 million increase related to MGP remediation costs. While the settlement for MGP remediation costs is lower than the original request, it also includes a provision to track these costs. If MGP remediation costs are higher than our annual collections from customers, NorthWestern Energy will track these costs and recover them in future years.

Commodity costs are adjusted monthly based on the price of natural gas.

NorthWestern Energy has been working over the years to remediate several MGP plants that date back to the early 1900s and pre-dated the introduction of natural gas systems. The plants converted coal and oil to gas for heating, lighting and cooking. Byproducts of this process include coal tar and purifier wastes which must now be remediated. Current MGP remediation costs relate to a site in Aberdeen, SD.

Customers with questions about our natural gas services, the proposed rate increases, or how to sign up for bill payment programs may call Customer Service at 800 245-6977, or stop by one of our local offices for assistance or visit www.northwesternenergy.com.

NorthWestern Announces the Winners of the Ultimate Fan Contest

web@northwestern.com — Fri, 18 Nov 2011 10:30:52 GMT

Butte, Mont. – November 18, 2011 – Three ultimate sports fans will be enjoying the remainder of the football season while saving energy thanks to their prize in NorthWestern Energy’s Ultimate Fan Contest.

During NorthWestern Energy’s Ultimate Fan Contest, which kicked off in September with NorthWestern Energy’s game day sponsorship events, almost 1,000 customers signed up for their chance to win a new 40” Energy Forward television (sponsored by Vann’s) and one of kind game memorabilia from each of the participating game day schools – the University of Montana, Montana State University, Montana Tech, and Carroll College.

NorthWestern Energy would like to congratulate the contest winners:

Matt Weatherman, Missoula, Montana
Brian Tocher, Butte, Montana
Tom and Maggi Corbett, Helena, Montana
Robin Eddy

“With the upcoming holiday season, many customers are considering the purchase of new televisions. We strongly encourage them to factor energy efficiency in their buying decisions because many of the new large televisions are energy hogs,” said Bill Thomas, Manager – Regulatory Support Services. “Look for the orange arrows “Most Efficient” label with the NorthWestern Energy logo on qualifying models at participating retailers for the super-efficient ENERGY STAR models. The label helps consumers makes shopping for the most energy efficient, technologically advanced TVs easy.” As we enter the holiday shopping season, NorthWestern Energy offers the following tips for TVs and other electronics.

Energy Forward – Engineered to be Most Efficient

The bright orange arrows and “Most Efficient” label on TVs identify models that are at least 30 percent more energy efficient than the ENERGY STAR threshold. More information, including a list of retailers and a complete list of super energy-efficient televisions, is available at www.energyefficientelectronics.org. Consumers can also join in the energy-efficiency conversation and enter “The Big Picture” contest on Facebook.

Screen Size Matters

Yes, it is possible for your television to be too big. Viewing experience actually diminishes if sitting too close to a very large high definition screen, particularly in small or moderately sized rooms. A rule of thumb for optimum viewing distance from a flat screen television is about two times the size of the screen. So if your couch is eight feet from the screen, you should have a television no larger than 48 inches.

Size also matters a lot in energy usage. On average, a 52-inch LCD television uses twice as much energy as a 32-inch LCD, according to an energy efficiency study by the technology website CNET. (get CNET’s comparison chart is here: http://reviews.cnet.com/green-tech/tv-consumption-chart/?tag=lna).

Adjust Your Settings

Almost all televisions arrive set to a "Vivid" mode that produces a bright and colorful picture. Consider changing the mode to "Standard," "Movie," "Cinema" or equivalent energy saver modes. The names will vary from manufacturer to manufacturer. This will improve picture quality and reduce brightness and power consumption.

Most TVs have an automatic Brightness Control, sometimes called “Energy Saver” mode that will raise and lower the screen brightness based on the amount of ambient light. Consider turning that option on and manually adjust screen brightness for best viewing comfort.

Beware of “Stand By” or “Quick Start” Modes

Some high definition televisions and other audiovisual devices come equipped with “Quick Start” or “Standby” buttons. In essence, this allows you to seemingly turn off your television or device without completely turning it off, allowing the device to fire up much more quickly when you want to use it again. What you may not know is these modes consume a lot of power — all while you aren’t using the television. Turn your television completely off; it will only take a few seconds for it to warm up when you turn it on again, and you will save electricity.

Use a power strip or universal remote to power down your television and other devices.

Newer televisions don’t use a lot of “vampire” power — power that is used even when the television is turned off entirely. But some of the devices associated with your television, which never turn off entirely, do. A high definition cable set-top box with DVR uses around 350-kilowatt hours of electricity per year – more than most home appliances.

You can switch off all vampire power by using a power strip to power all of your television-related devices, and switch it off when you’re not using them. You can also use a universal remote to power down all of the devices.

Look for the orange arrows and “Most Efficient” label on TVs at participating retailers to find the most energy efficient models. For more information, go to www.energyefficientelectronics.org.

NorthWestern Energy Reaches Stipulated Agreement with Montana Consumer Counsel

web@northwestern.com — Mon, 14 Nov 2011 15:05:21 GMT

Butte, Mont. – Nov. 14, 2011 – NorthWestern Energy (NYSE: NWE) has reached a stipulated agreement with the Montana Consumer Counsel (MCC) regarding the financial components of the proposed Spion Kop Wind Project in Central Montana.

NorthWestern announced its intent to purchase the 40 megawatt project in April 2011. If approved by the Montana Public Service Commission (MPSC), the proposed $86 million project is to be developed by Compass Wind and placed into utility rate-base for NorthWestern’s Montana electric retail customers. Both the energy and associated renewable energy credits will be used to meet the renewable portfolio standards obligations in Montana law.

A hearing on the project is scheduled in mid-December. Upon the completion of this hearing, NorthWestern and the MCC recommend that the Commission issue a final order approving, adopting, and implementing the terms of the Stipulation and Agreement. Specifically, NorthWestern and MCC agree that the following terms represent a fair and equitable resolution of the issues regarding return on equity, capital structure and future treatment of Spion Kop Project capital costs.

NorthWestern would be allowed an initial return on equity of 10-percent, along with its actual debt cost; an initial capital structure consisting of 52-percent debt and 48-percent equity and NorthWestern would agree to include the project in its next full general rate case so that its cost of capital and capital structure can be determined on a consolidated basis with NorthWestern’s Montana Electric Utility Operations. NorthWestern had asked for a 10.25% return on equity in the original filing in May 2011.

If the MPSC fails to grant approval for the Project on or before April 1, 2012, then either party may terminate this agreement. Construction would commence upon a favorable ruling, with commercial operation projected to begin by the end of 2012.

Western Electricity Coordinating Council Affirms MSTI Transmission Line Path Rating

web@northwestern.com — Thu, 29 Sep 2011 15:21:09 GMT

Butte, Mont. – Sept. 29, 2011 – The Western Electricity Coordinating Council (WECC) has notified NorthWestern Energy (NYSE:NWE) that the Mountain States Transmission Intertie (MSTI) has been approved to carry up to 1,500 megawatts of electricity north-to-south and up to 1,100 MW south-to-north.

WECC’s Three Phase Path Rating Process is a comprehensive technical planning study that defines the transfer limit that a new transmission line (or lines) can achieve without interfering with the reliability or stability of other lines in the western interconnection. In addition to technical modeling, the path rating process requires a peer review by all interested transmission providers and other stakeholders.

The company was recently notified that the project has received “Phase 3” status, which means that the study has been concluded, the path rating established and MSTI can be constructed with the approved rating. Phase 3 concludes when the project is placed into service. “This is an important project milestone that has been several years in the making,” said Mike Cashell, vice president – Transmission. “We still have much work to do before MSTI is in operation, but this and other recent studies affirm the regional benefit of this project to spur new energy development and alleviate congestion on the existing system.”

The WECC recently published a 10-year transmission planning study and the Northern Tier Transmission Group (NTTG) recently published its biennial planning report, both of which look at what the grid may look like in 2020 under different operating conditions. Both reports found that new transmission lines are needed throughout the west to accommodate demand for proposed renewable energy development. Both studies also found benefit (mostly in the form of congestion relief) should transmission be built to accommodate renewable energy development in Montana.

MSTI is still working its way through the siting process with the Bureau of Land Management and Montana Department of Environmental Quality. While the path rating is independent of the siting process, the path rating study did evaluate the “common corridor” approach to what has been termed the “northern route alternative” that may allow MSTI to more closely parallel the existing BPA double-circuited 500kv towers from Townsend to Deer Lodge. The rating was affirmed for all of the potential alternative routes, including the scenario that places MSTI in a common corridor with the BPA line.

NorthWestern Energy and Beacon Power Showcase Innovative Flywheel Project at Mill Creek

web@northwestern.com — Wed, 28 Sep 2011 15:00:00 GMT

Butte, Mont. – September 28, 2011 – NorthWestern Energy (NYSE: NWE) and Beacon Power Corporation, a provider of energy storage products and services that support the operation of the electricity grid, today showcased a project to install and test an advanced flywheel-based energy storage technology at the Dave Gates Generating Station (DGGS) at Mill Creek, near Anaconda.

Beacon Power is installing a 1-megawatt (MW) Smart Energy Matrix flywheel energy-storage system that will be operated in conjunction with the DGGS. The 1-MW system consists of ten, 1-kW flywheels along with two containers housing power electronics and environmental control systems. Construction of this project should be complete by the end of 2011.

“We’re pleased to collaborate with NorthWestern Energy on this innovative and forward-looking project,” said Bill Capp, Beacon Power President and CEO. “Studies have shown that fast-responding energy storage technology like our flywheels can augment conventional fossil-fueled regulation resources by improving their performance. We look forward to demonstrating this project and its operation with the DGGS.”

NorthWestern Energy, as does any electricity grid operator, must balance the electrical loads and resources, including intermittent resources such as wind, on its system on a moment-to-moment basis.

“NorthWestern Energy is pleased to work with Beacon Power to gain additional understanding of and operational experience with flywheel technology,” said Bob Rowe, President and CEO of NorthWestern Energy. “We are excited to learn more about this technology, and how it integrates with the operation of the Dave Gates Generating Station.

“I also find it interesting that flywheel technology has evolved from what was used for hoists in the Butte mines almost a century ago to this innovative energy-storage concept.”

The proposed flywheel system will respond to grid operator control signals to absorb excess electricity from the electric system and inject it back when needed, providing 1 MW of fast-responding regulation. Beacon and NorthWestern Energy will work closely together to develop the flywheel system’s control signal algorithms to integrate it with the performance of the adjacent DGGS and to evaluate the impact and potential benefits of the flywheel resource.

About Beacon Power

Beacon Power Corporation designs, develops and is commercializing advanced products and services to support stable, reliable and efficient electricity grid operation. Beacon’s Smart Energy Matrix™, now in production, being operated and earning revenue, is a non-polluting, fast-response flywheel-based solution designed to provide less expensive, more sustainable and effective regulation services to power grids around the world. The company’s business strategy is both to supply regulation services from its own plants and to sell systems directly to utilities or grid operators in parts of North America and selected international markets. Beacon is a publicly traded company with its research, development and manufacturing facility in the U.S. For more information, visit http://www.beaconpower.com.

NorthWestern Energy Supports MSTI Review Project

web@northwestern.com — Mon, 19 Sep 2011 10:47:20 GMT

Butte, Mont. – September 19, 2011 – Two Montana counties and five local non-governmental organizations have announced they will conduct an independent review of NorthWestern Energy’s Mountain States Transmission Intertie (MSTI) project.

NorthWestern Energy supports this third-party, independent review. The review will evaluate impacts and use a modeling process to analyze unbiased policy data, scientific data and community values. This process also assesses the economic impacts of the project to each county. Organizers of the third-party review process will be inviting all counties throughout the MSTI project area to participate.

“NorthWestern Energy has always been committed to transparent and factual communications about the project,” said Mike Cashell, Vice President - Transmission. “We think this is an excellent opportunity for county commissioners to continue to participate in a transparent and constructive public dialog that allows them to incorporate their important community values into the transmission siting equation. We hope that all counties potentially affected by MSTI will participate in this effort to better understand how this important project affects their county, state, and region.”

The MSTI Review Group includes: Madison County, MT; Jefferson County, MT; Western Environmental Law Center; Headwaters Economics; Sonoran Institute; Craighead Institute and Future West. Funding for the review process is expected to come from a variety of sources including counties, states, and NorthWestern Energy.

NorthWestern Energy Reminds Customers of Planned Outage in Hitchcock and Bonilla Areas

web@northwestern.com — Thu, 15 Sep 2011 09:34:46 GMT

Huron, S.D. – September 15, 2011 – NorthWestern Energy is reminding customers of a scheduled power outage for the cities of Hitchcock, Bonilla and surrounding rural customers on Friday, September 16. The outage will begin at 7:00 a.m. and is scheduled to last approximately 8 to 10 hours.

“We are excited to complete this final big step in bringing the new Hitchcock substation on-line,” said Rick Hoffman – Huron Area Manager. “The entire project will improve reliability and increase our ability to connect new and bigger electric loads.”

Customers are encouraged to plan and prepare in advance for this outage. As a reminder, keeping refrigerator and freezer doors closed helps to retain cold and sensitive electronic equipment should be turned off or unplugged until power is fully restored.

Customers who rely on electronically powered medical devices are strongly encouraged have ample battery back-up for the day.

Customers who plan to use electric generators during the outage are reminded that any generator that is directly wired into the home or business’ electric system are required to be installed with the appropriate safety mechanisms to prevent electricity from “back feeding” onto the system which poses a hazard to our employees working on the lines.

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

NORTHWESTERN ENERGY SIGNS AGREEMENT WITH OWNENERGY FOR MONTANA COMMUNITY WIND FARM

web@northwestern.com — Thu, 01 Sep 2011 12:10:14 GMT

Butte, MT – September 1, 2011 – NorthWestern Energy (NYSE: NWE), and OwnEnergy, Inc., a developer of Community Wind projects, today announced that they have signed a 25-year Qualifying Facility Agreement, for the 9.7 megawatt Two Dot Wind Farm. The project is located in Wheatland County, near the town of Two Dot, about 90 miles NW of Billings.

OwnEnergy will sell the electricity from the Community Wind farm to NorthWestern Energy under the terms and conditions set forth by the Montana Public Service Commission in the QF-1, Option 3 electric tariff. OwnEnergy and NorthWestern negotiated a long-term rate substantially below the current Qualifying Facility rate of $69.21. In return, OwnEnergy obtained curtailment provisions that are significantly more favorable than those contained in new Qualifying Facility Agreements.

The project is being developed as a result of the partnership between OwnEnergy and Two Dot Wind, LLC, whose owners, Dave Healow and Dana Dogetrom, are local businessmen. Two Dot Wind Farm exemplifies the central principles of Community Wind development - local ownership as well as greater involvement and financial upside for members of the community. Furthermore, as a wind development approach, Community Wind has demonstrated that it creates a greater number of local jobs.

OwnEnergy has taken a leadership role in the high-growth Community Wind sector, where its CEO serves on the AWEA Board as an advisor on the segment. Through its proprietary development technology and local partnerships, OwnEnergy has driven down the time and cost of developing these small to mid-sized wind projects and made them competitive in the market.

Jacob Susman, Founder and CEO of OwnEnergy, said, “This is an exciting milestone for OwnEnergy, Two Dot Wind, LLC and the local Montana community. NorthWestern has once again shown true leadership, demonstrating that power generation can be environmentally friendly at the same time as being cost-effective.”

“Thanks to this agreement, our customers will benefit from the addition of a renewable energy source at a rate more beneficial to ratepayers,” said John Hines, Vice President – Supply. “With our other recent wind QF purchases, we are nearing the limit of installed wind capacity that we are allowed to purchase through this tariff.” The Montana Public Service Commission set a rate for NorthWestern Energy to purchase up to 50MW of wind generation. When the company reaches the cap, the MPSC will reexamine the wind QF tariff and related policies.

Construction of the Two Dot Wind Farm will begin by spring of 2012.

About OwnEnergy

OwnEnergy, Inc. is a Community Wind developer of mid-sized, utility scale wind projects that enable landowners and communities to build and profit directly from their own local wind farms. The company is based in Brooklyn, New York. For more information about OwnEnergy visit www.ownenergy.net.

NorthWestern Energy Electric System Sets Another High Demand Mark

web@northwestern.com — Tue, 02 Aug 2011 11:06:46 GMT

Huron, S.D. - August 2, 2011 - Just 14 days ago NorthWestern Energy surpassed a four year old record of electricity demand by customers located in the South Dakota region of the utility. Today the utility announced after Monday’s intense heat and humidity last month’s record has fallen.

Heat indexes again pushed into triple digits, and in turn electric loads grew to an all time high for South Dakota. Demand pushed the system to a new peak of an estimated 341 megawatts (MW). Two weeks ago the record was set at 338 MW which had smashed the previous record set in 2007 at 315 MW.

"I would venture to say that nobody at NorthWestern thought we were going to break the July 18th record so soon, but it shows you the amount of energy your cooling system requires to keep up with temperatures in the 100's and a heavy blanket of humidity," said Dennis Wagner - Director of South Dakota Energy Supply, Production & Generation. "Tuesday's cloud cover and reduced temperatures will be a welcomed relief for air conditioners all over Eastern South Dakota."

NorthWestern Energy Electric System Hits All-Time High Demand Mark

web@northwestern.com — Tue, 19 Jul 2011 15:46:10 GMT

Huron, S.D. – July 19, 2011 – NorthWestern Energy announced today that the South Dakota electric utility surpassed its old all-time high for electricity demand during Monday’s afternoon swelter.

With heat indexes reaching 112° F, customers depended on air conditioning to stay comfortable. Cooling equipment and other electric demands pushed the system to a new peak of 331 megawatts (MW). The previous record was set at 315 MW in 2007.

“Typically, when you break an electric peak record, it is only by a megawatt or two,” said Dennis Wagner – Director of South Dakota Energy Supply, Production & Generation. “Monday was a big day of usage on our entire South Dakota system—not just in a few regions, but our entire coverage area.”

There was a bit of relief in the form of wind generation on Tuesday. Titan 1 Wind Farm near Ree Heights, S.D. added 15 MW of renewable energy to NorthWestern’s system around the noon hour, thanks to a steady wind that didn’t exist in that area on Monday.

NorthWestern Energy system is capacity rated at 352 MW.

web@northwestern.com — Fri, 10 Jun 2011 11:28:06 GMT

Butte, Mont. – The 2011 BetterBricks Awards event honored Montana’s leading green building professionals who design, build, operate and advocate for high performance commercial buildings. Held June 9, in Bozeman, the award ceremony drew approximately 100 attendees.

Judith Heerwagon, Program Specialist at the Office of Federal High Performance Green Buildings for the U.S. General Services Administration (GSA), was the keynote speaker. She spoke about how the interaction between building design and operations influences human behavior and performance and, in turn, affects building performance.

The BetterBricks Awards celebrate the champions of energy efficiency whose forward-thinking business practices raise the bar and industry standards. The Awards recognize architects, engineers, building operators, facility managers and other building professionals for their leadership in reducing the use of energy and other resources in commercial buildings.

“Northwest green building professionals lead the country in their commitment to energy efficiency,” said Claire Fulenwider, Executive Director of the Northwest Energy Efficiency Alliance (NEEA). “Our high caliber winners this year are making impressive strides in both private and the public sector buildings and demonstrate that through innovation and collaboration, we can accomplish significant energy savings.”

Winners were selected in the following categories:

Advocate: Thomas E. McNab
Director, Community Design Center, Adjunct Assistant Professor, Montana State University School of Architecture, Bozeman
Architect: Eric Simonsen
Principal, A&E Architects, Billings
Design Engineer: Ken Phillips, P.E.
Senior Energy Engineer, Montana State Building Energy Program, Helena
Facility Manager / Operator: Co-Winners
Richard Whitney, Executive Director of Facilities Services, Billings Public School District #2, Billings; Don Clark , Water/Wastewater Treatment Superintendent, City of Helena

Winners were selected by a panel of judges comprised of industry professionals, NorthWestern Energy employees and green building experts.

To achieve high performance buildings, award winners championed a variety of best practices such as utilizing local climate in site designs, employing early design energy modeling, supporting building commissioning, educating tenants and staff about sustainability and implementing better building operations. Their projects have achieved substantial energy savings, reduced building operation and maintenance costs and enhanced productivity of building occupants among other benefits.

The award ceremony was held in conjunction with the Montana Energy Conference for Businesses.

NorthWestern Energy Files Annual Electricity and Natural Gas Supply Trackers in Montana

web@northwestern.com — Fri, 03 Jun 2011 12:37:47 GMT

Butte, MT. – June 3, 2011 – NorthWestern Energy (NYSE: NWE) today announced it has submitted its annual filings with the Montana Public Service Commission to true-up its electricity and natural gas supply costs beginning July 1, 2011.

These costs are adjusted monthly based on forecasted market rates and are trued up once a year to adjust for any difference between the forecasted costs collected in rates and the actual costs incurred during the same period. At the same time, the company updates the forecasted electricity and natural gas supply rates.

The natural gas supply tracker includes NorthWestern Energy’s interest in Battle Creek natural gas production in Blaine County, Montana, acquired through two separate transactions in 2010 and early 2011. The associated costs are included in the 2011 tracker on an interim basis pending a revenue requirement filing that will be made later this year.

The natural gas supply rate as of July 1, 2011, will be $5.13 per dekatherm (10 therms) or $05.13 per therm – which compares to $5.69/per dekatherm at the same period last year. This lower rate indicates that natural gas prices over the coming tracker period are expected to remain about the same or slightly lower than last year; however, actual results depend on weather patterns, demand, and other market fundamental and factors.

The electric filing also includes adjustments for the variable costs and revenue credits associated with Colstrip Unit 4 and the Dave Gates Generating Station. The new electricity supply cost rates included in this filing are combined with the separate rate components for Colstrip Unit 4 and the Dave Gates Generating Station into a single overall supply rate and net deferred cost rate for customer billing purposes.

The projected overall Electric Supply Cost and net Supply Deferred Cost in this filing result in a decrease for a typical residential customer using 750 kWh per month of $0.24 per month or $2.88 per year on the total bill. This will result in an overall 0.53% decrease for supply-related costs.

However, overall bills are expect to increase slightly on July 1, 2011, due to the combined impact of rate changes associated with the Competitive Transition Charge for Qualifying Facilities (CTC-QF), and the reduced BPA Residential Exchange Credit. Including all July 1, 2011 rate adjustments, the total overall bill increase is estimated to be $0.36/per month or $4.32 annually. The actual increase will depend on each customer’s type and usage.

NorthWestern Energy Files Application for Approval to Purchase and Operate Montana Wind Farm

web@northwestern.com — Wed, 01 Jun 2011 12:29:54 GMT

Butte, MT. – June 1, 2011 – NorthWestern Energy (NYSE: NWE) is asking the Montana Public Service Commission (MPSC) for approval to purchase and operate the yet to be developed Spion Kop Wind Project located in Central Montana.

NorthWestern announced its intent to purchase the 40 megawatt project in April. If approved by the MPSC, the proposed $86.1 million project is to be developed by Compass Wind and placed into utility rate-base for NorthWestern’s Montana electric retail customers. Both the energy and associated renewable energy credits will be used to meet the renewable portfolio standards obligations in Montana law.

“The Spion Kop Wind Project is a valuable, cost-effective addition to the utility’s rate-base that is consistent with our most recent electricity supply resource plans,” said John Hines, vice president – supply. “The project helps NorthWestern maintain a balanced, environmentally responsible portfolio of generation resources that enhances rate stability for customers over the long-term and positively contributes to the economic base of Judith Basin County and Montana.”

For comparison purposes the Project represents a levelized price of $53.78 per megawatt hour (MWh) for a 25-year period, which was the lowest competitive bid price offered through a recent competitive solicitation process undertaken by NorthWestern and is significantly less than the current Qualifying Facility rate for a project with similar attributes of $69.21/MWh.

If the MPSC fails to grant approval for the Project on or before April 1, 2012, then either party may terminate this agreement. Construction would commence upon a favorable ruling, with commercial operation projected to begin by the end of 2012.

NorthWestern Energy Names New Executive Officers

web@northwestern.com — Fri, 27 May 2011 10:01:35 GMT

Butte, Mont./Sioux Falls, S.D. – May 27, 2011 – NorthWestern Energy (NYSE: NWE) announced today the appointment of two new members to the executive management team following the death of a senior executive in March.

Mike Cashell has been promoted from Chief Transmission Officer to Vice President - Transmission and John Hines has been promoted from Chief Energy Supply Officer to Vice President – Supply, effective immediately. The Board of Directors approved the appointments today in a special board meeting.

“In both natural gas and electricity, our key operational areas are supply, transmission, and distribution. These appointments maintain the alignment of the operational areas at the executive level and provide the high visibility and focus necessary to provide our customers the best possible service now and in the future,” said Bob Rowe, President and CEO.

Rowe explained, “Mike and John are effective and respected leaders both inside and outside NorthWestern. Together with their teams, they are responsible for numerous complicated and important tasks such as ensuring the adequacy and reliability of our extensive gas and electric transmission systems that tie together our service territory, keeping our network stable and in balance, and ensuring reliable energy supplies from diverse sources.”

Within the Supply area, Bill Rhoads, General Manager - Generation, and his team are now expanding their responsibility to include much of NorthWestern’s environmental compliance work. “We have significant work in both Montana and South Dakota which requires the focus of a dedicated team,” Rowe said.

In addition to the two new appointments, Curt Pohl’s title has been changed from Vice President – Retail Operations to Vice President – Distribution, better reflecting the scope of responsibilities, which include electric and natural gas distribution in Montana, Nebraska and South Dakota.

The position of Vice President – Wholesale Operations has been eliminated. Rowe said, “Heading up both supply and transmission, Dave Gates helped us develop to the point where our customers would best be served by having separate executive-level leads for each area.”

Cashell, a Butte Native, joined Montana Power in 1986 and has held various positions of increasing responsibility in the areas of transmission system and balancing authority operations, planning and maintenance, hydroelectric and thermal power system operation, independent power production, gas transmission and storage system operation and business management.

Cashell graduated from Montana Tech of the University of Montana with a Bachelor of Science degree in Engineering Science and attended the Public Utilities Executive Course at the University of Idaho. He is active in state and regional transmission and energy forums and represents NorthWestern Energy at the Western Electricity Coordinating Council. He currently serves on the board of the United Way in Butte – Silverbow. He and his wife Kathy have one daughter and live in Butte.

Hines joined NorthWestern Energy in 2005 as Director, Energy Supply Planning, and was responsible for leading the company’s energy supply planning and long-term procurement activities. Prior to joining NorthWestern, Hines was appointed to serve as one of Montana’s two representatives to the Northwest Power and Conservation Council from 2002 through 2004. Hines also worked as a senior economist at the Council.

Hines is a member of Edison Electric Institute’s ‘Energy Supply Executive Advisory Committee’ and the Pacific Northwest Utilities Conference Committee. Hines, a native of Bozeman, Montana, received his B.A and M.A. in Economics from the University of Montana. He and his wife Siobhan have two children, and live in Helena.

NorthWestern Energy Files Natural Gas Rate Adjustment with South Dakota Public Utility Commission

web@northwestern.com — Tue, 24 May 2011 11:30:31 GMT

Falls, S.D. – May 24, 2011 – NorthWestern Energy (NYSE: NWE) announced today that it has filed an application to adjust its rates for natural gas services in South Dakota.

NorthWestern Energy is requesting an increase of $4.1 million annually due to increased operations and maintenance costs and to complete the company’s remediation of manufactured gas plant (“MGP”) sites in South Dakota.

Approximately $1.4 million of the requested increase relates to the annual estimated MGP remediation costs. In the event MGP costs are lower than estimated during the time period, the difference would be subject to a refund to customers. Accordingly, while gross margin and operating expenses will fluctuate based on actual results, this portion of the rate request would have no change on operating income.

If approved by the South Dakota Public Utility Commission in its entirety, the average residential bill for natural gas service would increase $8.31 per month.

“Maintaining and operating a safe, reliable and adequate natural gas system for our customers and the communities we serve is our highest priority. We do everything we can to manage the costs that are under our control. Like many others, we are experiencing higher costs associated with operating and maintaining the natural gas system in South Dakota,” said Bob Rowe, President and CEO. “As we work to ensure the safe and reliable operation of our system and to meet our responsibility for ongoing environmental stewardship, we keep in mind customers’ concerns about rate increases.”

Natural gas customers in Nebraska are not affected by this filing. The rate filing covers operations and maintenance costs associated with the natural gas delivery service and do not affect the cost of the commodity. Commodity costs are adjusted monthly based on the price of natural gas.

There are several old MGP sites in NorthWestern Energy's system including Aberdeen, Huron, Mitchell and Yankton that date back to the early 1900s and pre-dated the introduction of natural gas systems. These plants converted coal and oil to gas for heating, lighting and cooking. Byproducts of this process included coal tar and purifier wastes which must be remediated. Over the years, NorthWestern Energy completed much of the remediation work at the Huron, Mitchell and Yankton sites. Remediation efforts are currently underway at the Aberdeen site.

Customers with questions about our natural gas services, the proposed rate increases, or how to sign up for bill payment programs may call Customer Service at 800 245-6977, or stop by one of our local offices for assistance or visit www.northwesternenergy.com.

NorthWestern Reports First Quarter 2011 Financial Results

web@northwestern.com — Wed, 27 Apr 2011 04:00:00 GMT

Reports improvement in diluted earnings per share of 12.7% over Q1 2010
Reaffirms guidance for 2011 of $2.25 - $2.40 per fully diluted share
Announces quarterly dividend of 36 cents per share

Sioux Falls, S.D. – April 26, 2011 – NorthWestern Corporation d/b/a NorthWestern Energy (NYSE: NWE) reported financial results for the quarter ended March 31, 2011.

Significant achievements for the quarter include:

Net income improved $3.9 million to $32.6 million, or $.89 per fully diluted share, for the first quarter of 2011 compared with $28.7 million, or $.79 per fully diluted share, in the first quarter of 2010 due primarily to:
- An increase in gross margin of $14.9 million primarily due to the addition of the Dave Gates Generating Station at Mill Creek (DGGS), and an increase in electric and natural gas volumes largely due to colder winter weather;
- Lower income tax expense of $3.0 million, primarily due to the regulatory flow-through treatment of accelerated depreciation deductions;
- Offset by an increase of $13.9 million in our operating expenses due primarily to increased operating costs, property taxes, and depreciation related to the addition of DGGS. In addition, we had increased labor costs and increased operating and maintenance costs primarily for proactive line maintenance.
The Company’s Board of Directors declared a common stock dividend of 36 cents per share, payable on June 30, 2011, to common shareholders of record as of June 15, 2011;
In March, NorthWestern received an accounting order from the Montana Public Service Commission (MPSC) to defer and amortize certain incremental operating and maintenance costs up to $16.9 million on our Distribution System Infrastructure Project for 2011 and 2012 over a 5 year period beginning 2013; and
Finally, we recently signed an asset purchase agreement, contingent on the MPSC approving the project into rate base, to develop a 40 megawatt wind project in central Montana.

NorthWestern Energy Reminds Excavators that April is National Safe Digging Month

web@northwestern.com — Mon, 18 Apr 2011 13:26:36 GMT

BUTTE, Mont. – April 18, 2011 – NorthWestern Energy reminds anyone who is going to excavate, trench, plow, drill, auger, blast, strip topsoil or level land is required by law to call 811 at least two working days before digging. Customers will need to have information ready when calling, such as:

Municipality, county, city
Street address or nearest intersection of streets
and roads, or township, range, section
and quarter
Type of work
Extent of work
Your name
Date and time excavation is scheduled to begin
Contractor or contact person and address
Phone number and call back times

Once the customer calls, they will need to wait for the site to be marked with paint, flags or stakes. If a contractor was hired, they must wait for the site to be marked before beginning work. Following safe digging helps to prevent injuries, property damage and inconvenient outages. “Our mission as a board is to protect personal safety and minimize damage to utility lines in our state,” said One Call Board President Bleau LaFave of NorthWestern Energy.

Excavators who damage underground facilities without first calling to request and obtain locates must pay the full cost of repairs. In the case of personal injury or loss of life, as the excavator, you may be subject to a civil suit. When electrical, natural gas, and other service lines are ruptured or damaged, the responsible excavator is charged for the repair.

NorthWestern Energy reminds customers to notify us immediately at (888) 467-2669 or to call 911 if they hit an electric or natural gas line or if they smell natural gas.

NorthWestern Energy Annual Natural Gas Inspections Underway Across Montana

web@northwestern.com — Mon, 18 Apr 2011 13:04:05 GMT

BUTTE , Mont. – April 18, 2011 – NorthWestern Energy’s natural gas distribution and transmission systems are undergoing their annual safety inspections across 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.

Employees are currently conducting annual leak surveys on the distribution systems in each community. Commercial districts are surveyed annually, while residential areas are surveyed every five 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. Employees also use 4 X 4 ATVs and Gators by driving over the lines, and also use a tool with an infrared light allowing workers to aim and detect leaks without walking on top of lines.

In addition, employees are conducting pipe-to-soil surveys that test steel pipes for potential corrosion. 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.

In all cases, NorthWestern Energy employees 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 smelling a rotten egg odor, 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: (888) 467-2669. 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 Warns of Scam

web@northwestern.com — Wed, 13 Apr 2011 15:54:54 GMT

Butte , Mont. – April 13, 2010 – NorthWestern Energy is warning customers and others of a check-cashing scam using the company’s name.

Several recipients in other states have reported receiving a check from NorthWestern Energy, LLC in the amount of $2,650 delivered via FedEx with a letter indicating that they have been chosen to participate in a survey. The letter directs them to deposit the funds in their account and immediately wire a portion of the money to a pre-determined “relative.” Recipients are then instructed to provide a host of details to the company called “Marketing Alts. Inc.”

Anyone who receives these checks should not deposit them. Please report them to your state’s fraud investigation unit or the other appropriate law enforcement agency in your area.

NorthWestern Energy appreciates the calls from recipients who have brought this to our attention. We encourage anyone who receives any suspicious correspondence to call us immediately with questions or concerns.

NorthWestern Energy Signs Asset Purchase Agreement with Compass Wind

web@northwestern.com — Tue, 12 Apr 2011 11:44:33 GMT

Butte, Mont. – April 12, 2011 – NorthWestern Energy (NYSE: NWE) has signed an asset purchase agreement to purchase a projected aggregate nameplate capacity of 40-megawatt wind project in Judith Basin County in Montana to be developed and constructed by Spion Kop Wind, LLC, a wholly-owned subsidiary of Compass Wind, LLC (“Compass”).

This project, known as the Spion Kop Wind Project (“Project”), consistent with recent Montana legislation that provides for the reintegration of the utility, is intended to be placed into utility rate-base for NorthWestern’s Montana electric retail customers. Both the energy and associated renewable energy credits will be placed into the electric supply portfolio and used to meet future renewable portfolio standards obligations.

NorthWestern had previously announced that it had entered into a memorandum of understanding to purchase a 24-megawatt wind farm in central Montana from Compass. NorthWestern has increased the size of the Spion Kop Wind Project to 40-megawatts.

The purchase price is $1,947 per kW for each kW of the total nameplate capacity included in the Project, which is equal to $77,880,000.

The purchase is conditioned on pre-approval of the Project by the Montana Public Service Commission (MPSC) to include the Project in NorthWestern’s rate base. As part of this condition, NorthWestern is to submit its application to the MPSC for pre-approval of the Project as an electricity supply resource. If the MPSC fails to grant approval for the Project on or before April 1, 2012, then either party may terminate this agreement.

Construction would commence upon a favorable ruling, with commercial operation projected to begin by the end of 2012.

NorthWestern Energy Annual Natural Gas Inspections Underway Across South Dakota and Nebraska

web@northwestern.com — Wed, 06 Apr 2011 11:24:08 GMT

Huron, S.D. – April 6, 2011 – NorthWestern Energy’s natural gas distribution and transmission systems are undergoing their annual safety inspections across South Dakota and Nebraska. 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.

Employees are currently conducting annual leak surveys on the distribution systems in each community. Commercial districts are surveyed annually, while residential areas are surveyed every five 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. Employees also use 4 X 4 ATVs and Gators by driving over the lines, and also use a tool with an infrared light allowing workers to aim and detect leaks without walking on top of lines.

In addition, employees are conducting pipe-to-soil surveys that test steel pipes for potential corrosion. 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.

In all cases, NorthWestern Energy employees 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 smelling a rotten egg odor, 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) 245-6977. 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 Renames Generating Station to Honor the Memory of Executive Officer

web@northwestern.com — Sat, 26 Mar 2011 14:00:00 GMT

Butte, Mont. – March 26, 2011 – NorthWestern Corporation d/b/a NorthWestern Energy (NYSE:NWE) today said that its Board of Directors have renamed the recently commissioned Mill Creek Generating Station as the Dave Gates Generating Station at Mill Creek to posthumously recognize Gates’ significant contributions to the company.

“The NorthWestern Energy family is mourning the loss of a great leader and a great friend,” said Bob Rowe, President and CEO. “Dave was a mentor, a friend and a visionary. Over the past week, we’ve been reminded of the extraordinary contributions Dave made to the company, to our communities and to the entire utility industry. As the leader who oversaw the successful completion of the Mill Creek Generating Station, the Board believed it was appropriate to rename the plant in permanent memory and recognition of the man and friend that we will forever miss.”

The Dave Gates Generating Station at Mill Creek is NorthWestern Energy’s first new generating plant to be built in Montana and marks an important step in the company’s post-deregulation strategy to operate in Montana as a vertically integrated utility. The natural gas-fired plant, located near Anaconda, Mont., entered commercial service on January 1, 2011 and provides regulating services to NorthWestern’s transmission system in Montana.

The resolution unanimously passed by the Board states:

WHEREAS, the Board of Directors (the “Board”) of NorthWestern Corporation (the “Company”) expresses its deepest respect and sympathy concerning the untimely death of David G. Gates, Vice President - Wholesale Operations for the Company on March 19, 2011; and

WHEREAS, Mr. Gates was instrumental in steering the Company’s efforts to return to being a vertically integrated utility by leading the Company’s successful construction and completion of the Mill Creek Generating Station; and

WHEREAS, the Board and the Company desire to honor the memory of Mr. Gates and his more than 30 years of service and many contributions to the Company;

NOW THEREFORE BE IT RESOLVED by the Board that the Company shall honor the memory of Mr. Gates and the significant and lasting contributions he made to all facets of the Company by renaming the Mill Creek Generating Station the “Dave Gates Generating Station at Mill Creek.”

FURTHER RESOLVED, that the Company is hereby authorized to furnish a suitable identifying memorial marker or markers and signage to identify the generating station as the Dave Gates Generating Station at Mill Creek; and

FURTHER RESOLVED, that the individuals appointed by the Board as executive officers of the Company (such officers and any of their Board-appointed successors shall be referred to herein as the “Authorized Officers”), are hereby authorized and empowered on behalf of the Company to take all such further actions and to do or cause to be done any and all acts as such Authorized Officers may deem necessary or appropriate to carry out the purposes and intentions of these resolutions; and

FURTHER RESOLVED, that any and all actions previously taken by any of the Authorized Officers in connection with or in furtherance of the foregoing resolutions are hereby ratified and approved in all respects.

IN WITNESS WHEREOF, each of the undersigned have executed this Consent in one or more counterparts, each of which shall be deemed to be one and the same instrument, as of the 26^th day of March, 2011.

“This is a very, very sad day for the entire NorthWestern Energy family. We have lost a great leader and a great friend,” said Bob Rowe, President and CEO. “Dave had firsthand experience in most parts of the business, starting as a young intern in Lewistown, Montana, more than 30 years ago. He was talented, hard-working, ethical and compassionate. We will miss his leadership, wisdom, warm humor and especially his friendship. Our thoughts and prayers are with the family during this difficult time.”

Missoula Family Celebrating Energy Efficiency Thanks to Home Energy Makeover

web@northwestern.com — Thu, 10 Mar 2011 09:34:28 GMT

Butte, Mont. – March 10, 2011 – The Becker Family of Missoula will be enjoying the improved comfort of their home while tracking all their energy savings thanks to their grand-prize winning entry in NorthWestern Energy’s Home Energy Makeover Contest.

The Becker’s entered the contest during the company’s fall Home Energy Expo events held around the state, where compact fluorescent lights (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. NorthWestern Energy preferred contractor, Anderson’s Heating, has installed energy efficient heating equipment, duct work and an ENERGY STAR^® water heater. In addition, a water heater tank wrap was installed and the home’s lighting fixtures have been updated with CFLs where appropriate. The family also received a new ENERGY STAR 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.

“This grand prize awarded to the Becker’s includes the installation of measures that typically provide customers the biggest energy savings for the investment. While not glamorous, low-cost measures such as CFLs, and 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 our 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.”

9:00 p.m. Update: NorthWestern Energy Extends Outage in Stevensville, Mont.

web@northwestern.com — Wed, 02 Mar 2011 20:41:42 GMT

Butte , Mont. – March 2, 2011 – NorthWestern Energy expects to fully restore power to Stevensville, Mont. customers by 10 p.m. A portable substation has been energized and crews are in the process of switching customers from temporary service to the portable unit.

An early morning fire in a three-phase voltage regulator located in the Stevensville City Substation caused an outage that initially affected approximately 3,000 customers. All but about 750 customers were restored to service within a few hours. The remaining customers will be back in power as crews complete the cut over to the portable substation. Permanent repairs to the damaged substation are pending once a full assessment is complete.

NorthWestern thanks and appreciates the patience and understanding customers have demonstrated throughout the duration of the outage. Here are a few reminders in case electric service to your home or business is interrupted:

During an outage, it’s a good idea to shut off appliances and lights. You may be able to prevent damage to some electronic devices, such as televisions and computers that are sensitive to voltage fluctuations. A surge suppressor between the outlet and your appliance also may help protect sensitive electronic equipment.
Keep refrigerator and freezer doors closed as much as possible to keep cold air in. A fully loaded freezer generally will keep goods frozen for two days if the freezer door is not opened. Refrigerators have insulation that will keep your food cold for a day or more with the door closed.
Keep a battery-operated radio on hand, so you can stay informed of weather reports and important announcements. In the event of an extended outage, tune to the Emergency Broadcast Station in your area for the latest information on the status of power restoration efforts.

12:00 p.m. Update: NorthWestern Energy Advises of Extended Outage in Stevensville, Mont. Area

web@northwestern.com — Wed, 02 Mar 2011 12:02:18 GMT

Butte , Mont. – March 2, 2011 – NorthWestern Energy crews have restored power to much of the Stevensville, Mont., area following an early morning fire in a piece of equipment located within the substation. A portable substation will be on site early this afternoon with complete restoration estimated around 8 p.m. this evening for the remaining customers still without service.

Power was restored within a few hours to many of the 3,000 customers initially affected; however, approximately 110 of those customers will experience a planned outage beginning around noon that is necessary to provide power for temporary shelters that are being set up at the City and Fire Halls. This planned outage will remain in effect until power is fully restored.

The planned outage includes the area along North Kootenai Cr, Middle Kootenai Cr, South Kootenai Cr, Shearbrook Lane and some customers along Hwy 93 north of the Stevensville Wye.

The company expects service to be restored shortly to customers south of Stevensville to Middle Burnt Fork Road. Approximately 440 customers are expected to remain without power until a portable substation is energized early this evening. In addition to the 110 customers in the planned outage area, another 330 customers in the central part of town are affected by the extended outage. Customers who have had their power restored should be aware that possible outages are possible throughout the day until power is fully restored.

NorthWestern estimates to complete power restoration around 8 p.m. this evening and will continue to provide updates as they become available. Here are a few reminders in case electric service to your home or business is interrupted:

During an outage, it’s a good idea to shut off appliances and lights.

NorthWestern Energy to Test Storage System of Flywheel Energy

web@northwestern.com — Mon, 28 Feb 2011 12:21:51 GMT

Butte , Mont. – Feb. 28, 2011 – The performance of NorthWestern Energy’s Mill Creek Generating Station has consistently met or exceeded all expectations in the weeks since it began operating west of Anaconda, Mont., and the company is already exploring the use of new technology to further enhance its performance.

NorthWestern has signed a 15-month lease with Beacon Power to test a 1 megawatt flywheel energy storage system at the plant. The system would be used in conjunction with Mill Creek’s mission to provide regulation resources to balance the company’s interconnected transmission grid operations in Montana.

“Kinetic energy has been used in various applications for centuries. Only recently has it been developed as a cutting edge resource that is now potentially available to grid operators to aid in the balancing of transmission systems,” said Bob Rowe, President and CEO NorthWestern Energy. “We’re interested to learn more about this technology and whether and how it may further enhance the performance of our new Mill Creek plant that provides regulating resources for the transmission system that serves our customers in Montana.”

A flywheel is a cylindrical rotor that is connected to the grid and accelerated to a very high speed. Electricity is stored in the system as rotational energy and converted back, when needed, by slowing down the flywheel. When power is needed, the inertia created by the spinning flywheel instantly turns the generator and produces electricity that is injected back onto the grid. The system is clean technology that is fully self-contained, doesn’t consume fossil fuels and does not generate any CO2 emissions.

As part of their agreement, Beacon and NorthWestern Energy will collaborate closely in developing the flywheel system’s control signal algorithms to best optimize the performance of the MCGS, and to evaluate and quantify the impact of the flywheel resource. The companies will also seek to determine the optimum amount of flywheel regulation capacity for MCGS should NorthWestern elect to expand the flywheel capacity.

The flywheel is planned to be operational by the end of 2011.

Gross Economic Output: The aggregated market value of goods and services produced by firms and government enterprises in the economy
Gross County Product: The total of value added created by the production of goods and services in the economy
Total Labor Income: The compensation to employees and self-employed proprietors including both wages and indirect payments such as retirement benefits, health insurance and other similar fringe benefits
Total Employment: The number of jobs generated within the impact area including full-time and part-time positions, salaried workers and sole proprietors
Capital Income: The sum of income such as business profits, interest and rental income
Indirect Business Tax: Taxes and fees not based in the businesses’ income. It may represent sales taxes (if any) levied by the state and county and also property taxes levied against businesses as well as federal, state and local fees.

Applicants may include cities, counties and local economic development organizations as well as existing large customers known as key accounts. Applicants must receive electricity or natural gas delivery service from NorthWestern Energy.

NorthWestern Energy Warns Customers of Possible Meter Damage Due to Thawing Weather

web@northwestern.com — Fri, 11 Feb 2011 09:37:31 GMT

Huron, S.D. – February 11, 2011 – NorthWestern Energy encourages customers to take appropriate steps to prevent potential damage caused by accumulated snow or ice falling onto natural gas pipelines and meters and overhead electric service or meters.

“Snow and ice buildup around or above natural gas and electric facilities increases the potential for danger,” said Mike Sydow – South Dakota and Nebraska General Manager of Operations. “With the expected higher temperatures this weekend, customers should look to ensure that falling snow or ice have not damaged or buried natural gas meters and piping or overhead electric lines and electric meter going into their home. They also should ensure that that ice or snow built up on a roof will not fall onto a meter or piping.”

The company also reminds customers to clear snow and ice away from natural gas meters cautiously to ensure the proper function of this device and to clear a path to the meters in case of a first responders needs to access emergency shutoff points quickly.

Customers may also want to inspect their furnace’s exhaust venting visually to ensure that it is clear of ice build-up or is not covered by snow. An external vent that is blocked can prevent the natural flow of deadly carbon monoxide out of your home.

NorthWestern Energy officials also warn customers to use caution and common sense around electric power lines while removing snow from roofs or knocking ice off eaves.

NorthWestern Energy Signs Memorandum of Understanding with Invenergy Wind

web@northwestern.com — Fri, 07 Jan 2011 11:32:19 GMT

Butte, Mont. – January 7, 2011 – NorthWestern Energy (NYSE: NWE) has signed a memorandum of understanding to purchase a 24-megawatt wind project in north central Montana to be developed and constructed by Invenergy Wind Development Montana, LLC, a wholly-owned subsidiary of Invenergy Wind LLC (“Invenergy”).

The project, which was submitted to NorthWestern in response to a 2009 community renewable resource solicitation, is consistent with recent Montana legislation that provides for the reintegration of the utility. The project is to be built on a portion of Invenergy’s proposed 200 megawatt Big Otter Wind Energy Project site near Belt, Montana. It is intended to be placed into the Montana utility’s rate base, with both the energy and associated renewable energy credits used to meet future renewable portfolio standard obligations.

Execution of a definitive agreement is expected in the first quarter of 2011. Submission of an application for pre-approval by the Montana Public Service Commission would follow, with an anticipated decision in early 2012. Construction would commence upon a favorable ruling, with commercial operation projected to begin by the end of 2012.

Invenergy also is the owner and operator of the Judith Gap Wind Energy Center in Harlowton, Montana.

NorthWestern Energy Mill Creek Generating Station Balancing the Transmission System for Montana

web@northwestern.com — Thu, 06 Jan 2011 09:58:54 GMT

Butte, Mont. – Jan. 6, 2011 – The employees of NorthWestern Energy’s Mill Creek Generating Station quietly celebrated the New Year at work, placing the 150-megawatt natural gas-fired regulating reserve power plant into commercial operation on January 1, 2011, shortly after midnight.

The $200 million dollar facility east of Anaconda, Montana, is on time and within budget and will contribute more than $8 million dollars in new annual revenue to the Anaconda-Deer Lodge County beginning in 2011. Ten permanent employees staff the facility which is operational around the clock. There were approximately 265 workers employed at the site at the height of construction, and thanks in part to a vigilant emphasis on safety, there were no serious injuries resulting in lost time accidents.

“We’re thrilled to add Mill Creek to our growing fleet of Montana generation resources to provide service to our customers at regulated cost-of-service rates,” said Bob Rowe, CEO. “It is equipped with state-of-the-art emissions control technology and demonstrates that Superfund land can be placed into productive use through effective remediation.”

The plant includes three 50-megawatt generating units with each generating unit consisting of two combustion turbine engines and a common generator. The combustion turbines are similar to those used on commercial airliners and employ sound buffers to limit audible noise. Plant emissions comply with all state and federal ambient air quality standards. NorthWestern has submitted a carbon-offset plan associated with the plant’s approval which will be reviewed by the Montana Public Service Commission later this year.

The Mill Creek Generating Station is one of the few of its kind in the country because it will primarily be a “regulating reserve” plant, which means that it provides the reserve capacity necessary to maintain transmission system reliability and balance on a moment-by-moment basis as demand and resources fluctuate.

The plant is designed with maximum operating flexibility so that NorthWestern is dependent on its own resource availability to meet operating requirements. NorthWestern has been relying on out-of-state third party providers for regulation service since the mid 1980s. The station will provide long term reliability and stability for this critical service.

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

web@northwestern.com — Wed, 22 Dec 2010 12:31:45 GMT

Huron, S.D. – December 22, 2010 – NorthWestern Energy customers who heat their homes with 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.

Note: Embeddable video: http://www.youtube.com/watch?v=30G8nJs-QKc

“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.”

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

NorthWestern Energy Submits Biennial Natural Gas Procurement Plan to Montana Public Service Commission

web@northwestern.com — Wed, 15 Dec 2010 15:47:37 GMT

Butte, Mont. – December 15, 2010 – With winter temperatures dipping well below the freezing mark, natural gas customers who are interested in how the company plans to purchase their gas supply will want to review the 2010 Natural Gas Biennial Procurement Plan submitted today to the Montana Public Service Commission (MPSC).

The plan sets forth NorthWestern Energy’s procurement strategies for meeting the natural gas supply needs of its retail customers through 2013.

NorthWestern closely followed the 2008 Plan during 2009 – 2011, which resulted in rate stability and adequate, reliable supply for customers. The plan submitted today is generally consistent with the 2008 Plan with some notable changes due to the fundamental changes in natural gas supply and demand that has developed over the past couple of years.

Market prices for natural gas are currently trading at 10 year lows, and the U.S. economy continues to experience difficulty in recovering from the recession. NorthWestern Energy has adjusted its hedging strategy to take advantage of these market changes and to purchase more of its supply at index values rather than known fixed prices.

The plan is submitted to the MPSC for review and comment. The plan is available to the public either through the MPSC or by visiting www.northwesternenergy.com.

Before Black Friday, Check Out These Tips for Choosing and Maintaining Energy-Efficient Electronics

web@northwestern.com — Wed, 24 Nov 2010 11:11:54 GMT

Butte, Mont. – November 24, 2010 – Consumers are spending more and more money on televisions and home theater components, sometimes shelling out thousands of dollars per household. To protect that investment, NorthWestern Energy and the Northwest Energy Efficiency Alliance, in partnership with other northwest utilities and retailers, suggests that shoppers consider both “before” and “after” purchase tips.

According to Dr. Raymond Soneira, President of DisplayMate Technologies Corporation (www.displaymate.com), following these steps should improve picture quality, reduce energy consumption (and cost), and therefore, reduce the amount of heat generated by the TV and lower its internal temperature.

Because heat and high temperature have an adverse effect on most electronic components, this should also increase the life of the television and reduce the need for servicing.

Energy Forward – Engineered to be Most Efficient

Northwest consumers in the market for new electronics should look for signage carrying a bright orange “Energy Forward” button, indicating electronics that are among the best made today — and that are also at least 30 percent more energy efficient than the ENERGY STAR threshold. More information, including a list of retailers and a complete list of super energy-efficient consumer electronics, is available at www.energyefficientelectronics.org. Consumers can also join in the energy-efficiency conversation at twitter.com/energy_forward and on Facebook.

Screen Size Matters

Yes, it is possible for your television to be too big. Viewing experience actually diminishes if sitting too close to a very large high definition screen, particularly in small or moderately sized rooms. A rule of thumb for optimum viewing distance from a flat screen television is about two times the size of the screen. So if your couch is eight feet from the screen, you should have a television no larger than 48 inches.

Size also matters a lot in energy usage. On average, a 52-inch LCD television uses twice as much energy as a 32-inch LCD, according to an energy efficiency study by the technology website CNET. (get CNET’s comparison chart is here: http://reviews.cnet.com/green-tech/tv-consumption-chart/?tag=lna).

Control Your Viewing Environment

Soneira notes, “All new televisions come preset from the factory set for maximum brightness and intense colors so that they will look good in the store, and they use more power when the screen is set to high brightness.”

Take the following steps to adjust brightness:

First, control and reduce ambient light in the TV viewing area — with window treatments, for example.
Orient the TV so that it isn't facing a window because the light will reflect back to the viewer. The lower the ambient light, the lower you can set the TV's brightness, which actually improves picture quality.
Arrange room lighting so lamps don't reflect off the screen into the eyes of any viewer. Turn off unnecessary lighting and consider getting light dimmers. Never watch TV in complete darkness, as it will cause eyestrain.

Adjust Your Settings

Almost all televisions arrive set to a "Vivid" mode that produces a bright and colorful picture. Consider changing the mode to "Standard," "Movie," "Cinema" or equivalent energy saver modes. The names will vary from manufacturer to manufacturer. This will improve picture quality and reduce brightness and power consumption.

Most TVs have an automatic Brightness Control, sometimes called “Energy Saver” mode that will raise and lower the screen brightness based on the amount of ambient light. Consider turning that option on and manually adjust screen brightness for best viewing comfort.

Beware of “Stand By” or “Quick Start” Modes

Some high definition televisions and other audiovisual devices come equipped with “Quick Start” or “Standby” buttons. In essence, this allows you to seemingly turn off your television or device without completely turning it off, allowing the device to fire up much more quickly when you want to use it again. What you may not know is these modes consume a lot of power — all while you aren’t using the television. Turn your television completely off; it will only take a few seconds for it to warm up when you turn it on again, and you will save electricity.

Use a power strip or universal remote to power down your television and other devices.

Newer televisions don’t use a lot of “vampire” power — power that is used even when the television is turned off entirely. But some of the devices associated with your television, which never turn off entirely, do. A high definition cable set-top box with DVR uses 350-kilowatt hours of electricity per year – more than most home appliances.

You can switch off all vampire power by using a power strip to power all of your television-related devices, and switch it off when you’re not using them. You can also use a universal remote to power down all of the devices.

Look for the orange “Energy Forward” label on TVs at participating retailers to find the most energy efficient models.

NorthWestern Energy Named a Recipient of the 2010 ServiceOne Award

web@northwestern.com — Thu, 18 Nov 2010 14:32:20 GMT

Butte, Mont./Huron, S.D. – November 18, 2010 Last night, NorthWestern Energy was recognized by PA Consulting Group (PA) as the recipient of the 2010 ServiceOne Award for Outstanding Customer Care Performance. The ServiceOne award is given annually to recognize utilities for their excellence in providing exceptional customer service.

”While we are technically in the business of providing electricity and natural gas, we really think of ourselves as being in the customer service business. The ServiceOne Award recognizes the hard work, dedication and commitment of our Customer Care team. But, delivering superior customer service is really a company effort and it takes the hard work and dedication of all of our employees to create a quality customer care experience,” said Bobbi Schroeppel, Vice President – Customer Care, Communications and Human Resources.

This is the sixth year out of seven that NorthWestern Energy has received the ServiceOne Award for Outstanding Customer Care Performance.

"Excellent customer service can only be achieved if it is a core value for a company. This is particularly the case in the utility sector, where increasing demands placed on customer service organizations have challenged traditional delivery strategies, business processes and modes of customer interaction," said Mike Hormell, PA's ServiceOne Program Director. NorthWestern Energy has successfully managed to create outstanding benefits for the customer through a combination of hard work, effective leadership, and an unwavering commitment to service."

The ServiceOne Award is based on a set of criteria that covers nearly all the functional areas within customer service operations typical for a North American utility. These functional areas include the contact center, billing, payment, revenue protection, credit and collections, meter reading and safety. Utilities that participate in PA Consulting Group’s annual Polaris Performance Benchmarking Program are considered for a ServiceOne Award. While PA administers the program, an advisory committee consisting of members within the Polaris program provides advice regarding its content and criteria.

NorthWestern Energy Plans Outage in Hazel, S.D., Area for House Move

web@northwestern.com — Wed, 17 Nov 2010 16:14:58 GMT

Huron, S.D. – November 17, 2010 – NorthWestern Energy has scheduled a power outage for the city of Hazel, S.D., and some surrounding areas to accommodate the moving of a house. The outage will begin Friday, November 19, 2010, at approximately 2:00 p.m., and will last an estimated one half hour.

The outage will affect customers located in the town of Hazel, South Dakota. Some farm customers and residential customers in Vienna, Bryant, Henry and Naples will also experience outages as the house moves through the service area.

“We understand this is an inconvenience for customers, and we thank you for your patience,” said Rick Hoffman – Huron Area Manager. “This brief outage will ensure that the house is clear of any overhead power lines while it is being moved along the road.”

State law requires utilities to provide safe clearance for scheduled building and other large structure moves taking place where overhead lines could be a danger.

If weather prevents the house move, the outage will be rescheduled.

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

NorthWestern Energy Announces Planned Outage in Hitchcock and Bonnilla Areas to Switch Power Over to New Substation

web@northwestern.com — Fri, 12 Nov 2010 15:49:21 GMT

Huron, S.D. – November 12, 2010 – NorthWestern Energy has scheduled a power outage for the cities of Hitchcock, Bonnilla and some surrounding rural customers beginning at 6:00 a.m. on Tuesday, November 16, 2010. The outage will last approximately 1½ hours.

“This is the final outage needed to switch the current electric load from the portable substation to the new Hitchcock Substation, making it fully operational,” said Rick Hoffman – Huron Area Manager. “The work is being conducted in the early morning hours in order to minimize interference with work, school and other schedules.”

The new substation is part of approximately $800,000 in upgrades to the electrical system in the Hitchcock area completed in 2010.

NorthWestern reminds customers this is an early morning outage and customers should set a back-up alarm clock that runs on battery or via a wind-up mechanism. Many cell phones also have daily alarm capabilities.

NorthWestern will alert customers of this outage via the media and the use of a pre-recorded phone message.

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

NorthWestern Energy Winter Forecast: Stable Prices with an Increasing Chance of Energy Efficiency

web@northwestern.com — Thu, 04 Nov 2010 11:08:27 GMT

Butte, Mont./Huron, S.D. – November 4, 2010 – NorthWestern Energy is predicting energy prices will be about the same this winter heating season as they were last year and perhaps even slightly lower, which is good news for customers.

However, with initial weather forecasts warning of a colder, wetter winter this year compared to last year, the company is encouraging customers to make their homes as energy efficient as possible to help mitigate the effects of weather.

“The price of natural gas and electricity is an important component of customer bills and people should be concerned about them,” said Bobbi Schroeppel, Vice President of Customer Care, Communications and Human Resources. “However, if the weather is colder than last year, heating equipment will be working harder and consuming more energy to maintain temperature.”

That’s why the company encourages customers to install low-cost and no-cost energy savings measures around their home before winter sets in, especially those who live in older homes that are likely to be less efficient than new homes. This includes installing window plastic, caulking around doors and windows, installing new or replacing worn door sweeps, installing foam gaskets in sockets, and installing insulation foam to seal leaks.

Programmable thermostats allow customers to conserve energy by presetting the furnace to ramp up and down based on a family’s schedule and save money in the process.

Customers with fuel burning appliances or space heaters (wood, natural gas, pellet, etc.) are encouraged to install carbon monoxide (CO) detectors to alert residents in the event of a buildup of the deadly gas within the home or office. The symptoms of carbon monoxide poisoning often mimic other winter illnesses such as cold or flu and include headache, dizziness, confusion, disorientation, nausea, and/or vomiting. If you suspect CO poisoning, seek fresh air immediately and call 911 for medical assistance.

NorthWestern Energy Submits Interim Rate Request for New Mill Creek Generating Station

web@northwestern.com — Tue, 12 Oct 2010 10:16:30 GMT

Butte, Mont. – Oct. 12, 2010 – NorthWestern Energy’s (NYSE:NWE) Mill Creek Generating Station will begin serving Montana electric customers by January 1, 2011, prompting the company to file an application to include it in energy supply rates on an interim basis until the actual revenue requirement is approved.

The 150-megawatt natural gas fired plant is the first newly constructed facility to be approved under the law which allows public utilities to obtain “preapproval” of electric generation resources prior to acquisition, or in this case, construction. The Montana Public Service Commission approved in part the preapproval application in May 2009 with the requirement that the company submit a compliance filing within 90 days after the plant is placed into commercial operation. The compliance filing will be used to determine the plant’s final revenue requirement.

The company has submitted an interim rate request based on costs in the original preapproval filing that updates for certain known and measurable changes. As a result, this interim addition of the Mill Creek Generating Station in energy supply rates is expected to add $4.12/month to the total bill of typical residential electric customers using 750 kWh/month.

“The Mill Creek Generating Station is an important contribution to providing our customers greater independence from regional market forces,” said Bob Rowe, CEO. “We have been relying on out-of-state third party providers for regulation service since the mid 1980s and the resource has been difficult to obtain, short- term in nature and expensive as regional providers keep more of this resource for their own transmission balancing needs.”

Rowe added, “We’re sensitive to the cost concerns in our local economy. Although rates will initially increase, the construction of Mill Creek will provide assurance that we will be able to continue to provide this critical regulation service to our customers over the long-term.”

The Mill Creek Generating Station will be one of the few of its kind in the country because it will primarily be a regulating reserve plant, which means that it provides the reserve capacity necessary to maintain transmission system reliability and balance on a minute-by-minute basis as demand and resources fluctuate. The $200 million dollar facility east of Anaconda, Montana is on-time and on-budget, has generated approximately 250 construction jobs at its peak, 10 permanent jobs and will contribute more than $8 million dollars in new annual revenue to the Anaconda-Deer Lodge County when it is finished.

NorthWestern Energy Purchases Battle Creek Natural Gas Field

web@northwestern.com — Wed, 22 Sep 2010 14:47:30 GMT

Butte, Mont. – Sept. 22, 2010 – NorthWestern Corporation d/b/a NorthWestern Energy (NYSE: NWE) today announced that it has purchased a majority interest in the Battle Creek Natural Gas Field on the Sweetgrass Arch in Blaine County, Montana (“Battle Creek Field”), from a private owner. The purchase also includes the seller’s interest in the Battle Creek Gas Gathering System Joint Venture.

The Battle Creek Field purchase consists of the seller’s interests in producing wells and a gathering system. The amount of net proven developed producing reserves purchased are estimated to be 7.6 billion cubic feet (“Bcf”). Annual net production attributable to the purchase is currently approximately 0.5 Bcf or about 2.2% of NorthWestern’s current annual consumption in Montana.

“Owning natural gas reserves is intended to provide customers with a source of rate-based energy that helps hedge against price volatility,” said Bob Rowe, President and CEO. “We are excited that we were able to purchase this relatively small production field which already serves our natural gas customers under a soon-to-expire purchase agreement. With this acquisition, we will continue to dedicate this resource to our natural gas customers and will not use it as a source of supply for our soon-to-be-completed Mill Creek generation station.”

Under the terms of the agreement, NorthWestern paid the seller $11.4 million cash for the majority interest in the Battle Creek Field assets including the gathering system. NorthWestern funded the transaction by drawing on its revolving credit facility, which after the purchase has an availability of approximately $160 million.

“We plan to seek approval of the Montana Public Service Commission to add our interest in the Battle Creek Field and the gathering system into our regulated rate base,” added Rowe. “It is both in our service territory, near Havre, Montana, and connected to our existing natural gas system. In addition, acquiring this well-defined and established producing field is consistent with our low risk profile by staying away from exploration.”

During the 2009 Montana legislative session, changes in state law occurred that allow NorthWestern to acquire natural gas production and gathering resources and, subject to regulatory approval, include them in the rate base.

NorthWestern Energy Announces Joint Transmission Planning Agreements with Western Area Power Administration

web@northwestern.com — Mon, 13 Sep 2010 14:26:27 GMT

NORTHWESTERN ENERGY ANNOUNCES JOINT TRANSMISSION PLANNING AGREEMENTS WITH WESTERN AREA POWER ADMINISTRATION

Butte, Mont. – September 13, 2010 – NorthWestern Energy (NYSE:NWE) is pleased to announce the signing of two separate Memorandums of Understanding (MOU) with Western Area Power Administration (Western) to coordinate planning of regional transmission projects.

Under the agreements, NorthWestern Energy and Western will undertake joint planning and study work to determine how the Montana Renewable Collector System (MTRCS) and the Mountain States Transmission Intertie (MSTI) projects may enhance Western’s Transmission Infrastructure Program's mission of enabling renewable energy development. Should these joint efforts identify value to Western, it could lead to further cooperative agreements between the utilities.

"We believe these MOUs provide a significant step forward in determining how NorthWestern and Western can work together to provide regional, cost-effective solutions for renewable project developers' transmission capacity needs," said Bob Rowe, NorthWestern Energy's President and CEO.

These agreements do not request or obligate any government funding for development or construction of any specific project. That does not preclude future participation by either party should the joint planning studies determine that there is value in participating.

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.
