City of Grand Terrace Approval

The Condor Energy Storage Project is a 200-Megawatt Battery Energy Storage System (BESS) facility on a 10-acre site located near the corner of Main and Taylor Streets in Grand Terrace, California. The Project site is located on one of the parcels that previously housed a portion of the Highgrove Steam Plant which was constructed in 1951 to provide local and regional power. By 2010, the plant had been mostly deconstructed.

The Project will consist of lithium-ion batteries installed with racks, inverters, switchgear, and other associated equipment to directly interconnect with the Southern California Edison (“SCE”) Highgrove Substation located directly north of the property. The improvements will include, but are not limited to, perimeter walls and fencing, landscaping, underground electric cables, concrete pads for the BESS equipment, substation control enclosure, static mast, overhead interconnection tower, undergrounding existing power poles, street dedication with sidewalk, curb and gutter, water retention basins, security access gates, lighting, and security cameras.


  • In late 2018 and early 2019, the Project team identified key substations in the greater Los Angeles area, including Highgrove substation, that would receive the most benefit from a battery storage facility.

    • This item supports Goal 3 to Promote Economic Development by establishing a use that is consistent with the Industrial Zoning District designation and support of reliable sustainable energy goals.
    • The Project will comply with Public Health and Safety Element which primary role is the protection of people who live and work within city limits and appropriate measures have been identified to protect against natural/man-made hazards and to minimize the social, economic, and environmental disruption from hazardous events.
    • The Applicant has included in the project description ample information regarding the project’s safety features, which will include continuous monitoring, shutdown system, built-in safes, multi-layer fire protection, and infrared monitors.
    • The Project Plans were distributed to various agencies and City Departments for review and comment. Staff received a comment letter from the Colton Joint Unified School District on November 17, 2021, in response to the IS/MND draft review period. A response was drafted by the City’s Environmental consultant MIG on November 23, 2021, addressing the Unified School District comments and concerns.

California Public Utilities Commission (CPUC) Approval

The Project’s resource adequacy power contract was approved via a competitive procurement process ordered as part of the CPUC’s Mid-term Reliability Orders.

The CPUC Mid-term Reliability Orders require California utilities to procure 15,500 megawatts of new power supply to meet the state’s dramatic need for additional power during peak summer months, caused by:

  • Increasing electricity demand
  • The increasing and accelerating impacts of climate change
  • The likelihood of additional fossil-fueled generation resource retirements
  • The likelihood of delays for procured new resources.

The Condor Project’s 200 megawatts of new power supply is a critical and approved part of meeting the CPUC mandated Mid-term Reliability need for summer 2023 and beyond.
