The Alamo Powerplant was constructed between 1982 and 1985 as part of the South State Water Project (SWP). The facility is located on the East Branch of the SWP, approximately 1.5 miles southeast of the SWP’s bifurcation into the West and East Branches. The powerplant generates electricity from SWP water flowing down the East Branch of the SWP.
The Alamo Powerplant facility operates under a conduit exemption, FERC Project No. 14579, which covers the 17 MW Alamo Powerplant and appurtenant facilities. The Alamo Powerplant was originally part of the licensed development for the South SWP Hydropower Project No. 2426.
