SUGAR LAND, TEXAS--May 15, 2017--Written by John Egan for Industrial Info Resources (Sugar Land, Texas)--"Energy storage" could be an answer to the rhetorical question often asked about renewable energy: "What happens when the sun doesn't shine and the wind doesn't blow?" But energy storage also was paired with gas-fired peaking plants to keep the lights on in Southern California last year after a leak shuttered the Aliso Canyon gas storage facility. And among non-utilities, demand is strong for residential and commercial energy storage projects, typically paired with a distributed energy resource (DER) like rooftop solar.
