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: July 2022 – January 2024
• Lewistown District: February 2024 – July 2024
• Havre District: April 2024 – October 2024
• Helena Division: June 2024 – May 2025
• Great Falls Division: August 2024 – May 2025
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.
Will I have to pay for the meter?
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?
Upgraded advanced metering infrastructure (AMI) meters provide useful customer benefits, such as timely detection of outages and real-time energy usage. However, Montana law allows residential customers to opt-out of the use of advanced metering devices.
Learn more about your options or download the Application to Opt-Out of Advanced Meter Infrastructure (AMI).
You can also contact the Montana Public Service Commission with questions about your rights to opt-out of the use of advanced metering devices at 1-800-646-6150.

Hebgen Dam flow increasing May 26 to enhance Madison River trout spawning gravel
Date: May 19, 2023
Butte, Mont. – May 19, 2023 – NorthWestern Energy will increase the volume of water releases from Hebgen Dam to flush fine sediments from Madison River gravel to enhance the quality of spawning gravels that support the healthy wild trout fishery.
Hebgen Dam outflows will gradually increase over several days to coincide with peak runoff in the West Fork Madison River and other tributary streams.
The flow release increase is planned to begin May 26 and will continue through the end of May. River recreationists should be aware of the changing conditions and take appropriate precautions.
The Madison River Flushing Flow Program is designed to augment natural river flows with surplus water in good snowpack years.
The 2023 flushing release from Hebgen Dam is a cooperative effort planned by: NorthWestern Energy; Montana Fish, Wildlife & Parks; Montana Department of Environmental Quality; the U.S. Bureau of Land Management; the U.S. Fish and Wildlife Service; and the U.S. Forest Service.
To protect the outlet of Quake Lake from erosion, the Madison River flows will be maintained at about 3,500 cubic feet per second at the Kirby Ranch stream gage.
NorthWestern Energy owns and operates Hebgen and Madison dams on the Madison River under a license issued by the Federal Energy Regulatory Commission.
For questions about the flushing release, contact NorthWestern Energy Manager Hydro License Compliance Andy Welch at 406-444-8115 or Andrew.Welch@northwestern.com.
