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.
