The Athos Power Plant is a proposed 908 MW hybrid solar and battery project located in Riverside County, California. The development project, consisting of 458 MW of solar and 450 MW of battery storage, is interconnected to Southern California Edison (SCE) within the CAISO region.
The project, identified as CAISO-1405 in the CAISO interconnection queue, entered the queue on May 1, 2017, and has a proposed commercial operation date of May 17, 2027. An Interconnection Agreement (IA) was executed on December 21, 2018. The point of interconnection (POI) is the Red Bluff Substation at 230kV. The Athos Power Plant has been the subject of recent news coverage.
