Southern California Edison (SCE) filed with FERC on Dec. 14 two Generator Interconnection Agreements with affiliate Southern California Edison Company Advanced Technology for two 10-MW energy storage projects.
On May 31, 2016, the California Public Utilities Commission (CPUC) issued Resolution E-4791, which authorized expedited procurement of storage resources to ensure electric reliability in the Los Angeles Basin due to limited operations of the damaged Aliso Canyon Gas Storage Facility. The resolution, among other things, required SCE to hold an expedited competitive energy storage procurement solicitation to help alleviate outage risks during the upcoming winter of 2016-2017. The resolution also requires SCE to take all reasonable steps to expedite the interconnection process to allow utility-owned or a third-party owned storage resources to connect to the grid. Storage projects secured through this solicitation are required to be online by Dec. 31, 2016. These GIAs and the projects they cover meet the state mandate.
The GIA for one of the projects describes it as consisting of: "All equipment and facilities comprising the Interconnection Customer’s 10 net MW (10 gross MW) inverter based (battery storage) ACES-013A generating facility at 13568-C Hamner Ave., in Ontario, California, as disclosed by the Interconnection Customer in its Interconnection Request, as may have been amended during the Interconnection Study process, which consists of (i) twenty (20) Tesla 500kW, 480 Volt inverters (ii) a 12kV collector system, (iii) the associated infrastructure and step-up transformers, (iv) meters and metering equipment, and (v) appurtenant equipment. The ACES-013A Project shall consist of the Generating Facility and the Interconnection Customer’s Interconnection Facilities. The maximum rated charging capacity of the Generating Facility is 10 MW."
The other GIA says this second project consists of: "All equipment and facilities comprising the Interconnection Customer’s 10 net MW (10 gross MW) inverter based (battery storage) ACES-013B generating facility at 13568-E Hamner Ave., in Ontario, California, as disclosed by the Interconnection Customer in its Interconnection Request, as may have been amended during the Interconnection Study process, which consists of (i) twenty (20) Tesla 500kW, 480 Volt inverters, (ii) a 12kV collector system, (iii) the associated infrastructure and step-up transformers, (iv) meters and metering equipment, and (v) appurtenant equipment. The ACES-013B Project shall consist of the Generating Facility and the Interconnection Customer’s Interconnection Facilities. The maximum rated charging capacity of the Generating Facility is 10 MW."
