https://eplanning.blm.gov/eplanning-ui/project/2001226/510Project Facility Description:
Solar Facility: The proposed Project would produce up to 500 MW solar photovoltaic generation and integrated energy storage facility located near Desert Center, California that would interconnect to Southern California Edison’s (SCE) 500 kilovolt (kV) Red Bluff Substation via one new 500 kV gen-tie line.
Substation: A project substation yard, located in the southeastern corner of the project area, would transform or “step up” the voltage from 34.5 kV to 500 kV. The area of the substation yard and associated equipment would be approximately 120,000 square feet (300 feet by 400 feet). The 500 kV substation would collect consolidated intermediate voltage cables from the medium voltage and PV collector system. Electrical transformers, switchgear, and related substation facilities would be designed and constructed to transform medium-voltage power from the Project’s delivery system to the 500 kV SCE system.
Battery Storage Facility: The Project would include a battery, flywheel, or other similar storage system capable of storing up to 500 MW of power. If provided, the storage system would consist of battery, flywheel banks, or other similar storage technology housed in electrical enclosures and buried electrical cable. The battery system would be concentrated near the Project switching station on approximately 20 acres in the southeastern area of the Project site.
Operation and maintenance building and ancillary facilities: A new O&M building would be constructed at the project site. The facility would be designed for project security, employee offices, and parts storage. The O&M building would be approximately 3,000 square feet in size. The facility would be designed with a comprehensive Supervisory Control and Data Acquisition System (SCADA) system to allow remote monitoring of facility operation and/or remote control of critical components. Electrical power for the O&M building and substation would be supplied via a new overhead or underground 12 kV distribution line from the existing SCE distribution system adjacent to the solar facility site.
