San Diego Gas & Electric (SDG&E) has taken the wraps off a new battery energy storage project that will store up to 2 megawatts of electricity -- enough to power 1,000 homes for four hours.
The new vanadium redox flow (VRF) battery substation was installed by Osaka, Japan-based Sumitomo Electric and will store renewable energy harnessed from solar panels and release it when resources are in high demand during peak business hours.
"We are delighted to see our first flow battery system operating in the U.S. through the multiple-use operation of the battery system in SDG&E's distribution network; we would like to prove its economic value and potential use on the electric grids," Junji Itoh, managing director of Sumitomo Electric, said in a statement.
