Pacific Gas and Electric has gone live with its first utility-scale, lithium-ion battery storage system.
The storage substation, located about 50 miles north of Sacramento, is made of 22 Tesla Powerpacks, each the size of a refrigerator. In all, the 500-kilowatt (KW) substation can store up to 2000KW hours (KWh) of power, enough to power up to 380 typical homes. The batteries can discharge at full power for four hours.
