San Diego Gas & Electric (SDG&E), a California-based investor-owned utility (IOU), has selected Mitsubishi Electric Corporation as the supplier of battery energy storage systems for the construction of four microgrids in its service area.
Mitsubishi Electric also announced the deal, in which San Diego Gas & Electric (SDG&E) will order a total of 39MW/180MWh of utility-scale battery storage systems for the construction of four microgrids.
The four microgrid projects planned by San Diego Gas & Electric were approved by the California Public Utilities Commission (CPUC) in late June and are scheduled to come online by the middle of next year.
The microgrids will be connected to the grids of Elliot, Clairemont, Paradise, Boulevard in San Diego and will provide power capacity and enhance grid resiliency, especially during peak summer power demand.
California's power system is under tremendous pressure during the summer, and the California Independent System Operator (CAISO), the state's main operator of the grid and wholesale electricity market, has long emphasized the important role energy storage plays in mitigating energy supply risks.
Mitsubishi Electric Corporation will provide and deploy its Emerald battery storage solution, which includes an integrated power plant control system consisting of an energy management system (EMS) and SCADA that oversees real-time battery storage system operation and provides a monitoring platform .
San Diego Gas & Electric (SDG&E) also ordered a 10MW/60MWh battery storage system from Mitsubishi Electric in March for the company's Pala-GomezCreek energy storage project, which it said at the time would be its eighth battery storage in California. project.
Meanwhile, Mitsubishi Electric's other recent energy storage activities include its entry into the European energy storage market, supplying battery storage systems with a combined storage capacity of 371MWh for four energy storage projects in Ireland, and providing a battery storage system for developer Innergex in The energy storage project co-located with solar power facilities developed in Chile provides a 425MWh battery energy storage system. Mitsubishi Electric is also building a 300GWh green hydrogen storage project in Utah, which will receive a $504 million loan from the U.S. Department of Energy to cover its construction costs.
