41685 20th St W - 10 acres SCE Shuttle Substation 9.97 Acres of Industrial Land Offered at $1,351,210 CAD in Palmdale, CA 93551

Vacant 9.97-acre parcel near SCE Shuttle Substation, Los Angeles County, CA. Utility-Scale Standalone BESS development site. ________________________________________ 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) is an allowed use under current zoning, subject to County ministerial site plan review and applicable CDFW mitigation fees. ________________________________________ Why This Site Matters Potential 85+ MW standalone BESS site The parcel appears capable of supporting utility-scale standalone battery energy storage development in the 85+ MW range, subject to interconnection and permitting review. Short gen-tie pathway The site offers an approximately 800-foot public ROW gen-tie pathway into Shuttle Substation. Avoids costly looping switchyard Unlike parcels seeking to tap the Acton–Palmdale–Shuttle 66-kV line directly, this site’s proximity to Shuttle Substation may eliminate the need for a looping switchyard, potentially avoiding approximately $7.3 million in interconnection-related infrastructure costs. Solves current queue project constraints The existing queued 85 MW BESS project appears constrained by limited site size and high looping switchyard costs. This parcel may provide a more practical platform for utility-scale storage development. ________________________________________ Interconnection / Deliverability Opportunity Cluster Study 15 identified interconnection and deliverability potential Phase I, Part I of Cluster Study 15 identified interconnection and deliverability potential via the Acton–Palmdale–Shuttle 66-kV circuit, and modest project-specific upgrade costs. Potential future queue headroom The currently queued 85 MW BESS project is reportedly being reconsidered or downsized, potentially increasing available interconnection headroom. Strategic utility-scale storage node Current distributed generation at the node remains limited: Generation Type Capacity Existing solar on Han Solo 12-kV 4.5 MW Queued BESS project (reportedly under reconsideration/downsize) 85 MW If the queued project is withdrawn or reduced, the Shuttle node may offer significant future interconnection opportunities. ________________________________________ Permitting / Due Diligence Advantages BESS allowed by right Battery storage is an allowed use in the M-1 zone pending ministerial site plan review. County support for BESS development Los Angeles County is actively considering code modifications intended to further facilitate battery storage development. Focused CEQA review pathway The primary environmental review trigger is expected to relate to removal of protected Western Joshua Tree specimens under the Western Joshua Tree Conservation Act, likely resulting in a supplementary CEQA review focused on this issue. Known biological mitigation cost Biological review completed; no biological constraints identified beyond Western Joshua Tree mitigation. Estimated mitigation fee is approximately $26,000 assuming complete removal within the M-1 footprint and limited removal for access through the A-2 frontage. No cultural constraints identified Cultural resource study completed; no significant cultural resources or values identified. ________________________________________ Site Advantages Large usable footprint Nearly 10 acres with majority industrial zoning. Known development costs Environmental due diligence completed. Lower interconnection cost profile Potentially avoids expensive looping switchyard costs. Strategic Antelope Valley location Located in an active Southern California storage and renewable energy corridor. ________________________________________ Example Development Potential Example configurations subject to interconnection and permitting review: Example Configuration Storage Capacity 30 MW / 120 MWh Mid-scale merchant storage 85 MW / 340 MWh Utility-scale standalone storage Larger systems Subject to interconnection review ________________________________________ 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 / Acton-Palmdale corridor are encouraged to inquire. Additional information available upon request, including biological and cultural studies, and grid interconnection-related analyses. Other substation-adjacent California energy development sites available.
