Massachusetts 1,500MW Mid-Duration Battery Energy Storage Systems Procurement

planned

Massachusetts electric distribution companies (EDCs) and the state's Department of Energy Resources (DOER) have launched a request for proposals (RFP) for approximately 1,500MW of mid-duration battery energy storage systems (BESS). This is the first phase in a staggered procurement schedule aiming to procure 5,000MW of energy storage by 2030. The procurement process includes proposal eligibility review, evaluation by a team comprising DOER, EDCs, and the Executive Office of Economic Development, and further evaluations based on viability, cost, risk, and effectiveness. Proposals must interconnect to the New England Independent System Operator (ISO-NE).
