[ESS Integration of 150MW/600MWh! Overnight Solar + ESS Project] Southern California Edison (SCE) has entered into a 15-year Resource Adequacy (RA) agreement with the US development arm of UK-based Atlantica Sustainable Infrastructure. The agreement covers the Overnight Solar + ESS Project located in San Bernardino County, California, which includes a 150MW/600MWh battery ESS.
