Renewable energy developer Agilitas Energy announced it has acquired Boston-based New England Battery Storage (NEBS), a private energy storage developer focused on utility-scale battery-based projects. The acquisition includes two operational ISO-New England merchant energy storage systems and one front-of-the-meter battery system in Maine totaling 25 MWh.

In Maine, two projects in the Town of Madison were commissioned as the first continuous storage systems in Maine as well as being one of the first and largest systems in New England. The project in the Town of Rumford, a 4.99-MW, 10-MWh front-of-the-meter battery, launched commercial operations this week. It will participate in the ISO-NE wholesale marketplace and has qualified as a capacity resource in FCA #15.

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

NEBS will be merged with the existing Agilitas Energy organization. Jeff Perry, CEO and President of NEBS, will become Vice President, Asset Management at Agilitas Energy. “Agilitas Energy is clearly emerging as an industry leader and we are excited to join them. The NEBS team brings to Agilitas Energy proven energy storage operating experience plus market leadership in Maine as they continue to build out their platform of solar and energy storage sites throughout the Northeast,” Jeff said. The acquisition makes Agilitas Energy the largest integrated solar and storage developer/operator in the Northeast.

“Energy storage is accelerating the transition to clean energy by enabling intermittent energy sources like solar and wind to be stored until they are needed on the grid. We are excited to have the experience and expertise of the NEBS team across our entire enterprise, which is critical as we develop hundreds of megawatts of storage projects,” said Barrett Bilotta, President of Agilitas Energy.
