SCE is launching the ACES 2 RFO in response to Senate Bill 801, which directed SCE to solicit for a minimum aggregate 20 MW of cost-effective energy storage resources to help address electrical system operational limitations resulting from reduced gas deliverability caused by the partial shutdown of the Aliso Canyon natural gas storage facility. The RFO seeks energy storage solutions including In-Front-Of-Meter (IFOM) Energy Storage (Resource Adequacy Only), IFOM Energy Storage (Resource Adequacy with Put), and Demand Response – Behind-The-Meter (BTM) Energy Storage options.
