The California Department of Water Resources and Los Angeles Department of Water and Power (Licensees) own and operate the South SWP Hydropower, an existing power recovery project that includes hydroelectric facilities, access roads, maintenance areas, recreation areas, rights-of-way, and other appurtenant facilities. The Licensees operate South SWP Hydropower under an existing FERC license that expires in 2022.
