San Diego Gas & Electric Company - Orange County - CAISO

Ortega Highway Energy Storage is SDG&E’s lithium-ion battery installation in San Juan Capistrano, Orange County. SDG&E’s portfolio materials describe the two-unit installation as 2 MW. The August 2026 EIA inventory distinguishes their status: SES1 has 1 MW of nameplate capacity and is operating, while the second 1 MW unit, SES2, is out of service and not expected to return in the next calendar year. Accordingly, the page’s 1 MW operating-inventory baseline should not be read as the total installed rating. This is a different facility from Fullmark Energy’s Ortega project in Lake Elsinore.
