Shuttle Substation Utility-Scale Standalone Battery Energy Storage Development Opportunity Location: Approximately 800 feet from Southern California Edison’s Shuttle Substation Utility: Southern California Edison Jurisdiction: Los Angeles County (unincorporated; Palmdale Sphere of Influence) Parcel Size: ~9.97 acres Zoning: ~7.8 acres M-1 (Light Industrial); ~2.2 acres A-2 (Agricultural) Use Potential: Battery Energy Storage Systems (BESS) are an allowed use under current M-1 zoning, subject to County ministerial site plan review and applicable CDFW mitigation requirements. ________________________________________ Why This Site Matters Potential 100+ MW Standalone BESS Site The parcel appears physically capable of supporting utility-scale standalone battery energy storage development in the 100+ MW range, subject to interconnection, site design, fire-code requirements, and permitting review. Short Gen-Tie Pathway The site offers an approximately 800-foot potential gen-tie pathway to Shuttle Substation, primarily within public ROW. Three 66-kV Circuits Connect Shuttle to the Antelope Valley System Three 66-kV circuits provide connections between Shuttle and SCE Antelope Substation through different portions of the Antelope Valley electrical system: • Antelope–Shuttle–Quartz Hill • Antelope–Acton–Palmdale–Shuttle • Antelope–Lancaster–Lanpri–Shuttle This three-circuit configuration provides multiple potential electrical pathways from Shuttle into the broader Antelope Valley system. ________________________________________ Permitting / Due Diligence Advantages BESS Allowed by Right Battery storage is an allowed use in the M-1 zone, subject to ministerial site plan review. Biological Review Completed No significant biological constraints identified. Western Joshua Tree mitigation calculated fee $26,250 for complete removal within the M-1 footprint and limited removal for access through the A-2 frontage. Cultural Resource Review Completed Cultural resource study completed; no significant cultural resources or values identified. ________________________________________ Site Advantages • Nearly 10 acres with approximately 7.8 acres of industrial zoning • Approximately 800 feet from SCE Shuttle Substation • Three 66-kV circuits connecting Shuttle into the Antelope Valley system • Short potential gen-tie pathway primarily within public ROW • Environmental due diligence completed • Known Western Joshua Tree mitigation requirements and cost calculation • Located in an active Southern California storage and renewable energy corridor • Located within the Antelope Valley TPD corridor ________________________________________ Example Development Potential Example configurations, subject to interconnection, site design, and permitting review: Example Configuration Storage Capacity 30 MW / 120 MWh Mid-scale merchant storage 100 MW / 400 MWh Utility-scale standalone storage Larger systems Subject to interconnection and site design ________________________________________ Offering 9.97-acre utility-scale standalone BESS site offered for sale, lease, or joint venture. Guidance Range: $995,000–$1,250,000 Developers seeking a utility-scale standalone battery storage platform in Los Angeles County’s Antelope Valley TPD corridor are encouraged to inquire. Additional information available upon request, including biological and cultural studies and grid/interconnection-related analyses.
