Massachusetts opens RFP seeking 1 GW of battery storage

The Massachusetts DOER and the state's investor-owned utilities, Eversource, National Grid and Unitil, issued the storage RFP on July 31. It seeks 1,000 MW of mid-duration BESS plus 250 MW to 300 MW of distribution projects, following a previous procurement that selected 1,268 MW of storage. The solicitation supports the state's statutory target to procure 5,000 MW of storage by July 31, 2030, a key requirement for integrating more renewables and managing peak demand.
