Massachusetts Awards 1.3 GW of Energy Storage: What Was Selected
Last verified: August 12, 2026. This is the editorial review date; confirm the current rule, program, docket, or issuing-authority document linked below before acting. Current status: source-specific status is stated only where the linked official record supports it.
Driving Towards a Sustainable Future
In a significant leap towards its renewable energy goals, Massachusetts has awarded 1.3 gigawatts (GW) of energy storage capacity through its inaugural large-scale procurement round. This initiative marks a crucial step in the state's ambitious plan to achieve 5,000 megawatts (MW) of operational energy storage by July 2030. The tender was launched as part of the Massachusetts Energy Storage Initiative, aimed at enhancing grid reliability, reducing energy costs, and fostering economic growth.
Details of the Awarded Projects
The Massachusetts Department of Energy Resources (DOER) selected four utility-scale battery projects totaling 1,268 MW under the Section 83E solicitation. This procurement attracted competitive bids, with 13 proposals submitted between 40 MW and 1 GW in size. The successful projects include:
- Jupiter Power's Trimount ESS
- LS Power's Riverside project
- FlatIron Energy's Energizar in Somerset and Salt Cod in Chelsea
- Rhynland Energy’s River Mill Storage in Tyngsborough
These projects are required to achieve commercial operation by January 1, 2030, with long-term contracts negotiated with major utilities such as Eversource, National Grid, and Unitil.
Context in the Broader U.S. Energy Storage Landscape
Massachusetts' efforts align with a nationwide trend, as the U.S. This surge is largely driven by utility-scale projects in Texas and California, highlighting a dynamic shift towards integrating renewable energy sources into the grid. Massachusetts is positioning itself as a leader in this sector, particularly with its focus on mid-duration battery systems that enhance grid stability and efficiency.
Conclusion: A Step Forward in Energy Innovation
As the state continues to develop its energy storage capabilities, it not only advances its environmental goals but also sets a precedent for other states to follow. Battery enthusiasts and industry stakeholders should keep a close eye on Massachusetts' progress, as these projects could serve as a model for future energy storage initiatives nationwide.
