Southern California Edison on July 30 filed with the Federal Energy Regulatory Commission a Large Generator Interconnection Agreement with Blythe Mesa Solar LLC and the California Independent System Operator (CAISO) for a 224-MW (net) solar photovoltaic project that is due for commercial operation by Sept. 30, 2018.

Said the LGIA: "The Generating Facility, located in Blythe, California, includes, but is not limited to, all equipment and facilities comprising the proposed Solar Star Blythe Mesa I generating facility, shown in the figure below, as disclosed by the Interconnection Customer in its Interconnection Request and as amended on January 2, 2013 during the CAISO One-Time Interconnecting Generator Downsizing Opportunity. The Generating Facility consists of (i) 12 SMA 500CP-US inverters with an individual output of 0.5 MW at the inverter terminal and 300 SMA 750CP-US inverters with an individual output of 0.75 MW at the inverter terminal for a collective total gross output of 231 MW at the inverter terminal and 7.0 MW auxiliary load resulting in a net output of 224 MW on the high side of the transformer banks given that no losses were identified through the collector feeders since no collector feeder impedances were provided, (ii) the associated infrastructure and step-up transformers, (iii) meters and metering equipment, and (iv) appurtenant equipment."

The LGIA added: "The Solar Star Blythe Mesa I Project shall consist of the Large Generating Facility and the Interconnection Customer’s Interconnection Facilities. Capacity at the Point of Interconnection for Interconnection Service will be 223.6 MW less losses incurred on the Colorado River-Solar Star Blythe Mesa I 220kV Transmission Line."
