Advanced Microgrid Solutions will be installing battery-storage systems throughout 2018 at 27 Walmart stores and at Irvine Ranch Water District, Irvine Co., the California State University Office of the Chancellor, and Cal State Long Beach. The new systems will boost their energy efficiency, reduce costs, and lower Southern California Edison’s electricity demand during times of peak usage. The installation of the battery-storage systems at the Walmart stores alone will create 40 megawatts of energy storage.
