Massachusetts's First Big Energy Storage Tender Dishes Out 1.3 GW Of Contracts - CleanTechnica

Massachusetts has set an ambitious target of achieving 5 gigawatts (GW) of energy storage capacity by 2030, as mandated by recent state legislation. To advance toward this goal, the Massachusetts Department of Energy Resources (DOER) conducted its first large-scale energy storage tender, awarding contracts totaling approximately 1.268 GW across four projects. Notable winners include Jupiter Power’s Trimount ESS, which will repurpose a former Exxon oil terminal in Everett into a clean energy hub, potentially deferring $2.2 billion in regional transmission upgrades. Other selected projects are FlatIron Energy’s Energizar in Somerset and Salt Cod in Chelsea, along with Rhynland Energy’s River Mill Storage in Tyngsborough. These projects will now enter contract negotiations with major electric distribution companies such as Eversource, National Grid, and Unitil to secure financial backing. While the tender specified a minimum of four hours of storage duration, the exact energy storage capacity in megawatt-hours (M
