An Act To Advance Long-Duration Energy Storage Within The State

This bill sets a new state target requiring at least 300 megawatts of long-duration battery storage capacity in Maine by December 31, 2035. Long-duration storage is defined as systems using commercially available technology capable of storing energy for eight hours or more. The Governor's Energy Office must reevaluate and potentially increase this goal every two years starting in 2024, reporting updates to the legislature. This policy directly affects energy storage developers, utilities, and infrastructure projects working to meet these targets within Maine.
