Battery maker Saft is to supply a third utility-scale storage system to California utility San Diego Gas and Electric (SDGE).
The contract is an addition of the first commission in 2012. Since then, Saft received two further contracts.
The lithium-ion energy storage system (ESS) is rated at 1MW/3MWh and housed in four containers. It will be used at an urban educational facility in California. The ESS will moderate the effects of shade on the rooftop solar power system by shifting energy and buffering during intermittent sunlight.
“This contract showcases the vital role of battery energy storage in advancing the power grid and enabling the integration of next-generation power sources,” said Blake Frye, vice president of sales and energy storage at Saft.
The commission by SDGE comprises of three ESS and one power electronics container, rated at 500kW/1500kWh and installed at a remote desert community microgrid in California.
The first ESS has been connected to a microgrid to power a large portion of a community during an emergency situation. Saft recently delivered and installed the second ESS for microgrid application at the same desert community substation.
The total combined ESS capacity delivered by Saft is now at 7.5MWh.
