NorthWestern Energy has filed a Green Power Program application with the Montana Public Service Commission to allow voluntary subscriptions to new renewable power. This initiative targets commercial businesses and local governments seeking to expand their clean energy access.
Why it matters
The program addresses demand from businesses and municipalities like Bozeman and Missoula that are aiming to reach 100% renewable energy use. It provides a structured path for operators to secure dedicated clean power supplies beyond the grid's current mix.
NorthWestern Energy currently sources 58% of its Montana power from renewables, as it now seeks to build additional capacity to meet a 100% target for participating local governments and businesses. Success depends on sufficient subscription interest to justify future project construction.
The players
NorthWestern Energy
An investor-owned utility providing electricity and natural gas to customers across Montana.
Montana Public Service Commission
The state regulatory body responsible for overseeing utility rates and infrastructure development projects.
The details
Under the proposed program, NorthWestern Energy would issue a request for proposals to build new renewable energy infrastructure. The initiative is voluntary and designed to scale based on verified customer interest. While primarily focused on commercial and government entities, residential access remains possible if individual local governments elect to open subscriptions to their residents.

Market Landscape
This filing represents a shift from mandatory portfolio compliance toward market-based subscription models for renewable infrastructure. It follows a pattern set by the Montana renewable energy portfolio standard while extending the capability for commercial users to contract for specific clean energy.
Commercial operators in participating areas should monitor the commission's review to assess if subscription terms align with their sustainability targets. Prospective participants should evaluate whether a voluntary power contract offers a more cost-effective path to carbon goals than on-site upgrades.
The takeaway
The proposed program allows businesses to dictate the pace of renewable energy build-outs through aggregated demand. Operators should review the upcoming Public Service Commission project approval timeline to gauge if subscription-based power fits their long-term facility energy strategy.
