Southern California Ed works out interconnect for 219-MW solar project

Southern California Edison on May 27 filed with the Federal Energy Regulatory Commission a Large Generator Interconnection Agreement with SP Blythe 1 LLC and the California Independent System Operator for a 219-MW solar project due in commercial operation in 2018.

Said the LGIA in describing the solar project: “All equipment and facilities comprising the Interconnection Customer’s 219.52 net MW (221 gross MW) photovoltaic generating facility in Blythe, 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) 442 SMA SC500HE inverter units with an individual rated output of 0.5 MW each for a collective total gross output of 221 MW at the inverter terminal, (ii) the associated infrastructure and step-up transformers, (iii) meters and metering equipment, (iv) appurtenant equipment, and (v) total auxiliary load of 1.48 MW. The Interconnection Customer did not indicate any collector system losses, therefore, the net output when taking into account auxiliary loads is 219.52 MW as measured at the high side of the main transformer bank. Losses on the 0.5 mile gen-tie were identified to be 0.1 MW resulting in an estimated 219.42 MW delivery at the Point of Interconnection.”

The project developer will install the Sandbox Substation and a new, approximately 0.5-mile 220-kV generation tie-line from the solar farm to a position outside of Southern California Edison’s Colorado River Substation. For purposes of this LGIA, the generation tie-line will be referred to as the Colorado River-Sandbox 220-kV Transmission Line.

The solar project’s targeted commercial operation date is Sept. 30, 2018.
