Vacant 9.7-acre parcel adjoining SCE Phelan Substation, Phelan, CA. Utility-Scale BESS / Solar + Storage development site. ________________________________________ Phelan Substation Standalone Storage / Solar + Storage Development Opportunity Location: Adjacent to the Southern California Edison Phelan Substation Utility: Southern California Edison Jurisdiction: San Bernardino County, California Parcel Size: ~9.7 acres Zoning: Service Commercial (CS) Use Potential: Utility-Scale Battery Energy Storage Systems (BESS) allowed use per zoning, subject to County approval; pre-application review completed ________________________________________ Why This Site Matters Underutilized storage node The Phelan Substation currently serves a relatively lightly developed distributed generation node, with limited existing solar and battery storage penetration compared with many SCE desert substations. This may create an opportunity for standalone merchant battery storage or solar + storage development. Phelan is a radial to SCE Victor Substation. Strategic substation adjacency The parcel lies directly adjacent to the Phelan Substation and offers one of the few privately controlled sites capable of supporting utility-scale energy storage immediately adjoining the node. Interconnection optionality The site offers access to multiple nearby voltage classes including 12-kV, 33-kV, and 115-kV infrastructure, allowing multiple potential development pathways. SCE operates all the circuits, including the 115-kV circuit; no CAISO applications likely for this substation. ________________________________________ Existing Distributed Generation / Queue Overview Current and under-construction projects at or near the Phelan node include approximately: Generation Type Capacity Existing solar on Keno 12-kV 4.5 MW Existing solar/BESS on Lotto 12-kV 2 MW/1.5 MWh Under-construction on Dice 33-kV 5 MW/16 MWh Queued on Dealer 12-kV 2 MW/1.5 MWh Compared to many California storage nodes, the Phelan area remains relatively lightly developed. ________________________________________ Electrical Infrastructure The parcel is directly adjacent to the Phelan Substation with immediate access to multiple circuits and voltage classes. Nearby infrastructure includes: • multiple 12-kV distribution circuits • 33-kV subtransmission infrastructure • 115-kV transmission/subtransmission infrastructure • short potential gen-tie pathways to the substation The property may support: • standalone merchant BESS development • solar + storage hybrid development • behind-the-meter / non-wires / community energy applications ________________________________________ Interconnection / Storage Opportunity Based on preliminary interconnection review and SCE Cluster 15 findings: • 115-kV interconnection scenarios showed no significant discharge-related overload constraints in reviewed cases • charging constraints are concentrated during summer daytime peak periods • materially higher charging availability exists overnight and early morning, which may support larger 4-hour BESS systems than a superficial review suggests • solar-assisted daytime charging may improve economics This creates a potentially attractive merchant storage opportunity. ________________________________________ Site Advantages Direct substation adjacency Parcel directly borders the Phelan Substation. County permitting path San Bernardino County pre-application review confirms focused review (visual screening, noise, air emissions) for utility-scale BESS development, 210- to 300-day review/approval process. Disturbed / developable land Flat, usable land with relatively low environmental constraints compared to remote desert parcels. Road access Direct access from Johnson Road. Strategic location Located within the Southern California High Desert growth corridor. ________________________________________ Example Development Potential Example configurations subject to interconnection and permitting review: Example Configuration Storage Capacity 10 MW / 40 MWh Community / merchant storage 20 MW / 80 MWh Mid-scale merchant storage 50 MW / 200 MWh Utility-scale storage Larger systems Subject to interconnection review ________________________________________ Offering 9.7-acre substation-adjacent parcel offered for sale, lease, or joint venture. Guidance range: $950,000 – $1,250,000 Developers seeking a foothold in a relatively under-built High Desert energy node are encouraged to inquire. Additional information available upon request, including preliminary interconnection analysis, County pre-application review documents, biological, cultural, and Phase I reports. Other substation-adjacent California energy development sites available.
