PG&E, California commission to unveil 4-MW battery project

Pacific Gas and Electric (PG&E) and the California Energy Commission plan a May 23 ribbon-cutting ceremony to unveil a 4-MW sodium-sulfur battery energy storage system in San Jose.

“As California adds more renewable energy to its electricity grid, the potential benefits of energy storage are receiving more attention,” the commission said in a notice about the ceremony. “Renewable energy resources, such as wind and solar, provide clean, sustainable energy but are intermittent. Battery energy storage systems can collect excess renewable energy when demand is low and then discharge the reserved power when demand grows.”

With support from the commission, PG&E recently completed the installation of a 4-MW battery energy storage system at HGST Inc. in San Jose. The system will undergo testing to evaluate how it can best improve power quality and reliability, support greater integration of intermittent renewable energy resources within the grid, and supply services to California electricity markets. The system will be the single largest battery energy storage system in California.
