Montana Meter Upgrade
NorthWestern Energy is upgrading our electric meters and gas modules.
- This technology upgrade will allow two-way communication between NorthWestern Energy and its meters on customer homes and businesses.
- In most cases, the system will notify NorthWestern Energy of an outage.
- Crews can restore service faster.
- Current energy use information is available for customer questions about bills, energy use and opportunities for energy savings
- System voltage information identifies problems before those problems cause outages.
The energy landscape is changing — and so are our customers’ expectations. As we modernize the energy grid, including using two-way communicating meters, also known as smart meters, our customers will benefit.
Moving Toward a Sustainable Energy Future
Moving Toward a Sustainable Energy Future
The energy grid is evolving, driven by the need to support more renewable resources as we transition to an even cleaner energy future. Smart metering provides more data on grid operations, which will allow opportunities for new customer programs and technology that will help balance the energy grid with renewable resources.

Who will change my meter?
A NorthWestern Energy employee will install your new meter or module.
Will I have to pay for the meter?
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.
When will the meters be installed and do I need to be home?
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.
What happens to the meter on my home or business now?
NorthWestern Energy has a contract to recycle the electric meters and gas modules in use now when new meters and modules are installed.
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 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.
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.
How do I read my meter?

NorthWestern Energy, City of Missoula, Missoula County and City of Bozeman File Proposed Green Power Program with Montana Public Service Commission
Date: Sep 15, 2026
TYPE: News
Butte, Mont. – Sept. 15, 2026 – NorthWestern Energy, the City of Missoula, Missoula County and the City of Bozeman filed a joint application today with the Montana Public Service Commission for a proposed Green Power Program.
The program would allow interested communities and businesses to support development of a new renewable energy resource located in Montana and give residential customers in those communities an opportunity to support those environmental priorities. The proposed program was developed collaboratively to support local sustainability initiatives, expand customer options and help participating customers pursue renewable energy goals through voluntary participation.
The filing with the Montana Public Service Commission is a proposed tariff to establish the framework for the Green Power Program, as well as proposed subscription agreements and customer forms. The application also includes proposed:
• Program eligibility and participation requirements.
• Subscription and cost-recovery mechanisms.
• Customer protections and program administration.
• Measures intended to ensure non-participating customers do not bear program costs.
“The proposed Green Power Program reflects a practical, customer-driven approach that addresses evolving community interests and customer demand for additional renewable energy options while ensuring only participants bear any additional costs and receive the benefits of participation," said NorthWestern Energy Director Regulatory Affairs Charlie Lane. “NorthWestern Energy, the City of Missoula, Missoula County and the City of Bozeman have worked together to develop a program tailored to Montana customers and communities. Filing this application marks an important milestone in that work."
“We are so pleased to mark another milestone in moving this project forward,” Missoula Mayor Andrea Davis said. “Years of collaborative work have brought an outstanding project that could support new renewable energy resources in Montana and offer customers voluntary options. We’re looking forward to the next steps with the PSC.”
“This program has been years in the making, and we're thrilled to see it reach this crucial milestone,” said Missoula County Commissioner Josh Slotnick. “The Green Power Program will give more communities, businesses and households the opportunity to support new, Montana-based renewable energy.”
“Filing the Green Power Program at the Public Service Commission is an important step forward for Bozeman residents,” said Bozeman Mayor Joey Morrison. “We know both residents and businesses have been asking for the option to sign up for Montana-made renewable energy. This is an opportunity that could benefit not just our local community but the entire state, and we’re looking forward to hearing what the Commission decides."
The application is now before the Montana Public Service Commission for review and consideration. If approved by the Montana Public Service Commission and supported by sufficient subscriber commitments, the program will move forward with a request for proposals for a new renewable energy generation resource located in Montana.
