PG&E selects partner for world’s largest energy storage plant


Pacific Gas & Electric Company (PG&E) has selected esVolta to develop an energy storage system in Santa Clara County, California.

esVolta will develop, build, and operate the Hummingbird Energy Storage project, a 75MW / 300MWh lithium-ion battery storage facility.

The energy storage system is expected to be complete by December 2020. The project will be the largest battery system in the world, according to a statement.

The system is being designed to help PG&E provide affordable and reliable energy to its customers. The plant will provide ancillary services to California’s grid whilst enhancing reliability, especially during peaks.

The system is expected to help California achieve its renewable energy targets as it will facilitate integration of renewable energy resources including solar and wind.
