Capacity of Mojave Solar project now set at 275 MW, up from 250 MW

Southern California Edison on Sept. 25 filed with the Federal Energy Regulatory Commission an amended Standard Large Generator Interconnection Agreement with Mojave Solar LLC and the California Independent System Operator that accounts for a 25-MW boost in the capacity of what was a 250-MW project.

The original LGIA provides the terms and conditions under which SCE and the CAISO will provide Interconnection Service for a 250-MW solar thermal generating facility located in San Bernardino County, California, identified as CAISO Q#125. This generating facility consists of two units: the Alba solar field and generating unit; and the Ocaso solar field and generating unit.

The project interconnects to SCE’s Kramer Substation 220-kV bus. The original LGIA was accepted for filing by FERC in 2011. Then more recently, Mojave Solar submitted an interconnection request in the CAISO’s Queue Cluster 5 window for a 25 MW capacity increase to the CAISO Q#125 project that is achieved from additional capability within the two generating units previously studied and is not the result of the installation of additional generating units or changes to the two generating units that have previously been studied and approved by the CAISO and Southern California Edison.

The CAISO and SCE conducted Interconnection Studies for this request, under CAISO Q#909, which determined that no additional interconnection facilities, distribution upgrades, or network upgrades were required to accommodate the proposed capacity increase. The amended LGIA incorporates the CAISO Q#909 project into the agreement such that the Mojave Solar Project is now a 275-MW facility.
