San Diego Gas & Electric’s South Orange County Reliability Enhancement primarily consists of rebuilding the substation in San Juan Capistrano, upgrading the transmission lines from the 138-kV and 12-kV to 230-kV, replacing select wood, steel and lattice towers with taller new steel fire-resistant poles, and upgrading the Talega Substation in San Clemente. This is a $400M project. It is currently mired in the approval process.
