Share

The Massachusetts Department of Energy Resources (DOER) has announced the winners of its first storage procurement, also called a Section 83E energy storage solicitation. The state selected four large-scale projects totaling 1,268 MW, as it aims to reach a legislative demanded 5,000 MW of operational storage capacity by July, 2030.

The winning projects include Jupiter Power’s Trimount ESS, set to be situated at a former 100-year-old Exxon oil terminal in Everett. The fossil fuel legacy infrastructure will become a wider hub for clean energy, and in doing so, the project is expected to defer some $2.2 billion in regional transmission upgrades.

Elsewhere, FlatIron Energy secured two slots in the tender with its Energizar project in Somerset and the Salt Cod development in Chelsea. Rounding out the selection is Rhynland Energy’s River Mill Storage in Tyngsborough.

While the durations of each project were not immediately published, the tender called for four-hour minimum durations, implying some 5,072 MWh of storage duration, however this number is unverified. An immediate reply to an emailed question was not forthcoming.
