MT BESS Facilities


Battery Energy Storage System (BESS) facilities in MT state provide a critical bridge between renewable generation and reliable power delivery. By storing excess energy from solar, wind, and other sources, these sites help balance the grid, support peak demand, and improve resilience during outages. Increasingly paired with renewable farms and microgrids, MT state-level BESS projects also enable participation in virtual power plants (VPPs) and deliver services such as frequency regulation and backup power for critical infrastructure.
