Gas meter

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

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

Advanced Meter FAQs
What is the advanced meter project timeline in Montana?
NorthWestern Energy began installation in Montana in 2021. Here is a list of approximate dates for the Montana Meter Upgrade project by area:
- Missoula Division: completed August 2022
- Butte Division: completed June 2022
- Bozeman Division: completed May 2024
- Billings Division: completed October 2024
- Lewistown District: completed October 2024
- Havre District: completed November 2024
- Helena Division: June 2024 – May 2025
- Great Falls Division: August 2024 – May 2025
Will I have to pay for the meter?
Who will change my meter?
NorthWestern Energy contracted with Tru-Check to install the new digital meters, the same company that installed the first generation, one-way communication digital meters in 1998 that are in use today.
Tru-Check technicians will wear apparel with the Tru-Check logo and will carry a NorthWestern Energy contractor identification badge.
When will the meters be installed and do I need to be home?
Most of the installations will occur Monday through Friday 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.
If you are both an electric and natural gas NorthWestern Energy customer, the new electric meter will be installed first and the new gas module will be installed during a follow-up visit to your home or business in about eight weeks.
What happens to the meter on my home or business now?
Are radio frequency (RF) emissions coming from the meters and modules?
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 the one-way communication meters in use now and the two-way communication meters that are being installed for this technology upgrade are both approved by the FCC. Radio frequency emissions are also produced by common household devices such as microwaves, baby monitors and TVs.
Is customer information protected?
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.What if I don’t want an upgraded meter?
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.

NorthWestern Energy’s upgrade of Black Eagle Dam spillway beginning
Date: Mar 11, 2025
Great Falls, Mont. –March 11, 2025 – NorthWestern Energy is starting a major project to upgrade the spillway of the Black Eagle Dam on the Missouri River. This project will enhance the safety and reliability of the hydroelectric facility.
Removal of Boat Restraint Barrier
- March 12, Crews will remove the boat restraint barrier that is typically installed 500 feet above Black Eagle Dam to allow access for the barge and construction materials. The barrier will not be replaced until the project is completed. Paddlers, boaters, and other users should exercise caution when recreating on the water above Black Eagle Dam and, for safety, stay out of the area directly above the dam.
Road and Trail Closures*
- March 13, North River Road adjacent to the Black Eagle Powerhouse and the associated section of the River’s Edge Trail will be closed March 13, 2025 while a barge anchor structure is installed north of the Missouri River.
- March 14, North River Road will be closed from the barge landing site east of NorthWestern Energy’s Great Falls office at 1501 North River Road to Black Eagle Memorial Island Park. The River’s Edge Trail will also be closed adjacent to the barge landing site. A crane that will be used for the work will be assembled on the road, then moved to the barge landing site.
*Dates may change due to inclement weather
Trail User Delays*
- March 17-20, Crews and equipment will be on and near the River’s Edge Trail on the southside of the Missouri River upstream of Black Eagle Dam, installing a barge anchor. Trail users may experience short delays as equipment and material cross the trail for the work.
- March 17 – 21, Equipment and materials to construct the barge that will carry the crane used for the project will be delivered to the barge landing site off North River Road. River’s Edge Trail users are asked to watch for flaggers and are
advised that they may experience short delays as equipment and material cross the trail for the work.
*Dates may change due to inclement weather
Project Details:
The upgrade will include installing new support structures and components of the spillway to improve the dam’s integrity and eliminate the need for manual ice removal, which is currently performed by NorthWestern Energy hydro crews during frigid temperatures. The upgrade will improve the safety of the workers and the efficiency of the operation.
A barge will be located upstream from Black Eagle Dam to transport materials and equipment for the project. The barge landing is located on the north side of the Missouri River, upstream from Black Eagle Dam.
The upgrade project is expected to be completed in 2027.
