San José Clean Energy Unveils New, Innovative Solar and Battery Storage
The innovative Kern Solar and Battery Storage Project built by Terra-Gen is providing power for SJCE customers in a unique format: fixed delivery of 62 megawatts (MW)
As of 2025, the site's battery storage facility is one of the largest in the world, at 630 MW (power) and 2,500 MWh (energy). The energy storage facility stores excess electricity (usually lower-price solar electricity during the daytime) for later use during periods of higher electricity demand (usually evening hours).
