Agilitas Energy, an integrated distributed solar and energy storage developer and owner/operator focused on the Northeast, acquired Boston-based New England Battery Storage (NEBS), a private energy storage developer focused on utility-scale battery storage.

Alongside NEBS, Agilitas will also acquire two operational ISO-New England (ISO-NE) merchant battery systems and one front-of-the-meter battery system in Maine, all totaling 25 MWh in capacity. The two merchant batteries were commissioned as the first continuous storage systems in Maine, while the front-of-the-meter battery system in Rumford, Maine, achieved commercial operation today, clocking in at 5 MW/10 MWh.

This acquisition marks Agilitas Energy’s expansion into battery energy storage operations, including participating in the ISO-NE day-ahead and real-time energy markets, operating reserve markets, frequency regulation market, and the forward capacity market. One of the three systems also serves as a peak load reducer for a municipal electric company alongside participating in ISO-NE’s wholesale marketplace.

Elsewhere in New England, Agilitas has begun pre-construction work on what is expected to be the largest stand-alone battery energy storage project in Rhode Island, a 3 MW/9 MWh lithium-ion system in Pascoag. Including that project, Agilitas is developing 300 MW of solar and energy storage projects throughout the Northeast, including 46 MW of storage and 40 MW of utility scale solar under construction in Massachusetts, New York and Rhode Island. All of that capacity is expected to go online in 2022.
