The region’s largest battery yet recently came online in Massachusetts, where state climate policies aimed at cleaning up the grid are boosting the tech.

Enormous new batteries keep appearing on the grid, making it devilishly tricky to keep track of which is the biggest in a given region. That’s certainly the case in New England, where acute power needs and robust state climate goals are fueling a buildout of big batteries that keep breaking capacity records.
Canary Media recently covered the inauguration of the 175-megawatt Cross Town battery in Gorham, Maine, which was the largest in New England when it began operating in late November. But that trophy has already passed to a 250-megawatt facility in Medway, Massachusetts, southwest of Boston and about 10 miles from the Patriots’ Gillette Stadium.
The Medway battery came online fully Feb. 25, according to developer VC Renewables, a subsidiary of global energy trader Vitol.
“To be fair, I don’t expect Medway to hold that title for very long, either,” said Tom Bitting, managing director at Advantage Capital, which supported the project with a $158 million tax equity deal. “There are other batteries being developed in New England that are bigger, but I think it is all just a sign that we need all of it, and there’s huge demand for it.”
For instance, Jupiter Power, a heavyweight in Texas’ booming grid storage market, is developing the 700-megawatt/2.8-gigawatt-hour Trimount battery plant at a former oil-storage site in Everett, Massachusetts, just north of Boston. Jupiter aims to finish the project in 2028 or 2029. Trimount is slated to be among the largest stand-alone batteries in the whole country — Vistra’s battery in Moss Landing, California, set that record with 750 megawatts/3 gigawatt-hours, before much of that capacity burned up in a disastrous fire.
