Southern California Ed files interconnect for 10-MW Center storage project

Southern California Edison on Dec. 13 filed with the Federal Energy Reegulatory Commission a Generator Interconnection Agreement with Southern California Edison Co. Generation for a 10-MW battery storage project at an existing power plant.

These sister companies are already parties to a Large Generator Interconnection Agreement that became effective on June 27, 2007, for a 47.13-MW gas generator facility, which has Full Capacity Deliverability Status. This has been called the Center Peaker Project. The LGIA is now being terminated and replaced with the new GIA.

On May 31, 2016, the California Public Utilities Commission (CPUC) issued Resolution E-4791. The resolution authorized expedited procurement of storage resources to ensure electric reliability in the Los Angeles Basin due to limited operations of the 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. Storage projects secured through this solicitation are required to be online by Dec. 31, 2016. Pursuant to this resolution, on July 15, 2016, the generation arm of the company submitted an Interconnection Request to add 10 MW of battery storage and to add 2.77 MW of incremental generation output to the existing facility.

The project would interconnect to SCE’s Center Substation 66 kV Bus to transmit energy to the California Independent System Operator-controlled grid. The combined facility is being renamed as the Center EGT Install Project, which is located in Norwalk, California. The generation company proposes a commercial operation date of Dec. 23, 2016 for the project.
