Gas meter

Natural gas dials represent the amount of natural gas measured in volumes of hundreds of cubic feet (ccf). 

A gas meter is driven by the force of the moving gas in the pipe, and also turns faster as the flow increases. Each time the dial with the lower value makes one complete revolution, the pointer on the next higher value dial moves ahead one digit.

To read your meter: 

  • Be at eye level of the dials.
  • Mark the dials from left to right.
  • Take note of the direction of the arrows on the display – the pointer of adjacent dials turn in opposite directions to each other.
  • Draw the pointer on the dials as displayed on your gas meter.
  • When the pointer on the dial is between two numbers, record the lower number.
    • If the pointer is between 9 and 0, 9 is the lower number.
  • When the pointer is directly on the number, look at the dial to its right:
    • Has the dial on the right has passed 0, yes, use the number that the pointer is on.
    • The dial on the right has not passed "0," use the number less than what the pointer is on.

Example:

In the example below, the reading is: 6 2 3 8

Electric meter

The basic unit of measure of electric power is the watt.  One thousand watts is called a kilowatt. 

When you use one thousand watts of power in one hour, you have used one kilowatt (kWh).

We bill you by the kWh. Your electric meter is a digital meter that has an electronic display that displays the current reading, like a digital clock.

When reading an electric meter, write down the numbers as shown on the meter.



Example:

In the example below, the reading is: 0 0 2 1 0 8

No. The electric meters and gas modules are purchased and owned by NorthWestern Energy. They are part of our infrastructure, similar to our power poles and transformers.

A NorthWestern Energy employee will install your new meter or module.

Most of the installations will occur during business hours, though there will be cases when evening or weekend installations may be necessary. Customers don't need to be home.

A door hanger will let residents know their upgrade was successful. If the technician cannot perform the upgrade, a door hanger will be left with instructions to call to make an appointment.

NorthWestern Energy has a contract to recycle the electric meters and gas modules in use now when new meters and modules are installed.

Yes. The Federal Communications Commission (FCC) regulates the safety limits for all RF emissions, and smart meter and module emissions make up a small portion of the limit. The RF emissions of old one-way communication meters and the new two-way communication meters are both approved by the FCC. Radio frequency emissions are also produced by common household devices such as microwaves, baby monitors and TVs.

Yes. Customer privacy and security are NorthWestern Energy priorities. The company’s strict security standards have contributed to protecting the energy grid and customer privacy for years. The meters do not collect, store or transmit any personally identifiable information.

The meters measure total energy and cannot differentiate energy usage by appliance or anything else within a home or business. The transmitted energy use information is encrypted.

Customers who want to keep their existing meters can call NorthWestern at 888-467-2669 or email NorthWesternEnergyMeters@northwestern.com to be added to the bypass list. Customers who previously requested an opt out do not need to contact NorthWestern again to be bypassed and keep their meters.

NorthWestern will be reaching out to customers who received an advanced meter despite their request to opt out. For those who still wish to opt-out, NorthWestern will ensure that the advanced meter is removed and replaced with a meter similar to the one that was there before. Customers will not be charged for this service. 

Customers who have questions about the advanced meter opt-out program can contact NorthWestern at 888-467-2669
or the Montana Public Service Commission at 1-800-646-6150 or pschelp@mt.gov.

From the Court to the Community: NorthWestern Energy Delivers $2,500 to Boys & Girls Clubs of Yellowstone County

Date: Apr 2, 2026

TYPE: News

Billings, Mont. – April 2, 2026 – NorthWestern Energy donated $2,500 to the Boys & Girls Clubs of Yellowstone County following our “Make a Basket, Make a Difference” event held during the 43rd Annual Spring Home Improvement Show, March 6–8, at the Expo Center and Montana Pavilion in Billings.

Throughout the three‑day event, show attendees stopped by NorthWestern Energy’s booth to play our pop‑a‑shot basketball game. Each basket made translated into a donation, with the final total reflecting the enthusiasm and generosity of this community.

“We were excited to see so many people participate and have fun while supporting a great cause,” said Molly Schwend, NorthWestern Energy community relations manager. “Thanks to the strong turnout and all those shots made, we’re proud to donate $2,500 to the Boys & Girls Clubs of Yellowstone County and support the important work they do for local youth.”

The funds will help the Boys & Girls Clubs of Yellowstone County continue providing mentoring, educational enrichment, positive role models, and a safe, welcoming place for young people in the community.

“Community partnerships like this make a real difference for the kids and families we serve,” said Karrie Owen, vice president of donor advancement for the Boys & Girls Clubs of Yellowstone County. “We are grateful to NorthWestern Energy and everyone who took part in the event. Their support helps ensure our members have access to programs that encourage learning, confidence, and success.”

Last year NorthWestern Energy provided more than $2.1 million in donations, sponsorships, and other support for the communities we serve, where our employees work, live and raise their families, including more than $586,000 in recognition of our employees’ volunteerism.

The Boys & Girls Clubs of Yellowstone County has served the Billings community since 1971. Today, the organization operates five Clubhouses serving nearly 1,200 elementary, middle, and high school students, with a mission to enable all young people—especially those who need it most—to realize their full potential as productive, caring, and responsible citizens.
