BHE Montana energized its Glacier Battery System, a $100 million advanced energy storage facility in Cut Bank, Mont.

The Glacier Battery System has a capacity of 75 megawatts for two hours, which is enough electricity to power approximately 60,000 homes for two hours.

“The energization of the Glacier Battery System marks a significant milestone in our commitment to delivering reliable energy to the region,” Ed Rihn, CEO of BHE Montana, said. “This project strengthens our ability to balance supply and demand and ensures customers have the power they need, when they need it.”

“The Glacier Battery System is a prime example of Montana’s commitment to creating jobs and bolstering energy development. This project and the work by BHE Montana will help keep costs affordable for families across the region, secure future energy resilience for Montana communities, and strengthen our national security,” U.S. Sen. Steve Daines (R-MT) said.

BHE Montana began construction of the Glacier Solar Park, a 130-megawatt solar generation project, in October 2025.

BHE Montana also operates the 189-megawatt Rim Rock windfarm near Kevin, Montana, as well as the 105-megawatt Glacier I and 103.5-megawatt Glacier II windfarms in Glacier and Toole counties.
