Granite Source Power (GSP), a renewable energy project developer, and its partner, New Energy Capital, an alternative asset manager, announced the sale of 1,250 MW of standalone battery energy storage projects across ERCOT, SPP, and ISONE.

Marc Rizzo, Co-Founder of Granite Source Power, stated, “We are thrilled to expand our partnerships and connect our projects with reliable buyers. In competitive landscapes, identifying appealing and unique opportunities has been crucial for enhancing the marketability of our projects. Our collaboration with NEC has been instrumental in this regard, enabling us to swiftly seize and implement value-adding opportunities that ultimately benefit the buyers of our projects.”
