Battery storage is helping utilities do their jobs. And by extension, it will — in time — help energy managers. Just off the lot: a 8.75 megawatt project that captures and reuses energy created by braking subway cars along two subway lines.
It’s now one of the nation’s largest customer-sited battery storage networks that will assist the Southeastern Pennsylvania Transportation Authority (SEPTA) in reducing its operating costs, ensuring energy resiliency and supporting the stability of the electric grid — a project owned and funded by Constellation Energy, a unit of Exelon Corp. In this case, SEPTA will finance the deal through a 20-year services agreement with Constellation.
