Southern California Edison (SCE) on Dec. 20 filed with the Federal Energy Regulatory Commission a Generator Interconnection Agreement with PPA Grand Johanna LLC for a 2 MW storage project.

The utility also filed a notice of cancellation of a prior Engineering, Design, Procurement and Construction Letter Agreement for this project, which is superseded by the GIA.

In May 2016, the California Public Utility Commission (CPUC) issued a resolution authorizing 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 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.

Pursuant to this resolution, on June 17, PPA Grand Johanna submitted an Interconnection Request to interconnect 2 MW battery storage project named the 2 MW Powin Bess, Irvine, California Project located in Irvine, California. It wants SCE to interconnect the project on the Virgo 12 kV distribution line out of the Estrella 66/12 kV Substation to transmit energy to the California Independent System Operator-controlled grid.
