en.Wedoany.com Reported - On July 6, electric utility companies in Massachusetts submitted long-term contracts for a 1,118MW energy storage project, entering state-level regulatory proceedings. These contracts correspond to projects selected in Massachusetts' first energy storage procurement round, with relevant documents filed with the Massachusetts Department of Public Utilities on July 2, pending regulatory review.

The submitted energy storage projects include three projects. Among them, the Trimount energy storage project, with a capacity of 700MW, is developed by Jupiter Power and located on a portion of a former oil terminal site in Everett; the Energizar energy storage project, with a capacity of 250MW, and the Salt Cod energy storage project, with a capacity of 168MW, are both developed by Flatiron Energy. The combined capacity of the three energy storage projects reaches 1,118MW, providing long-term flexible resources for the Massachusetts power grid.

Massachusetts' first energy storage procurement round selected four projects totaling 1,268MW at the end of 2025. The submission of contracts for the 1,118MW energy storage project indicates that the major projects have entered the contract regulatory process. Energy storage projects can be used for grid peak shaving, reserve capacity, renewable energy integration, and local power system support. As the state advances its second energy storage procurement round, the role of energy storage projects in the power system will continue to expand. Subsequent progress depends on regulatory review, contract effectiveness, project financing, equipment delivery, and grid connection construction arrangements.
