The Lake Elsinore Advanced Pumped Storage Project is a proposed 500 MW pumped storage development in Riverside County, California. The project is located within the CAISO region and is interconnected with San Diego Gas & Electric (SDGE). It entered the CAISO interconnection queue as queue ID CAISO-72 on June 21, 2005, with a proposed commercial operation date of December 31, 2028.
The project's Interconnection Agreement (IA) was executed on August 11, 2012. The point of interconnection (POI) is the proposed Lee Lake Substation at 500 kV. The Lake Elsinore Advanced Pumped Storage Project has been the subject of recent news coverage related to regulatory matters.
