PSE to build a 248 MW utility-scale wind project in Stillwater County, Montana

Last month, PSE announced we are developing the Beaver Creek wind farm, a utility-scale wind project that will be located on the high plains in Stillwater County, Montana. As we work to add more clean energy to our portfolio to meet statutory obligations outlined in Washington’s Clean Energy Transformation Act, we are continuing to partner in Montana’s energy economy and invest in its communities.

Initially, the wind farm will generate about 248 megawatts (MW), enough energy to power about 83,000 homes per year. Additionally, there will be an opportunity to add wind turbines in neighboring Sweet Grass County, as well as a lithium-ion battery energy storage system to shape Beaver Creek’s variable wind output and better match PSE’s customer energy needs. Montana wind has a high production rate that is especially valuable during extremely cold weather in the Pacific Northwest, when high pressure systems mean that Washington wind farms produce less energy.

The project will interconnect on NorthWestern Energy’s system and will use existing PSE transmission on the Colstrip Transmission System to bring the wind energy back to PSE customers. Construction is set to begin in the spring of 2024, and the facility is expected to start operations in 2025.
