FERC approved interconnection agreement between Southern California Edison and Longroad for 500-MW battery storage project
sourceThe ROSA STORAGE project is a proposed 511.73 MW battery storage development in Ventura County, California. The project is located within the CAISO region and is interconnected with Southern California Edison (SCE) at the Moorpark Substation 230 kV. It entered the CAISO interconnection queue as queue ID CAISO-2092 on April 15, 2021, with a proposed commercial operation date of June 27, 2034. The project's interconnection status is currently in the System Impact Study phase.
The ROSA STORAGE project has been the subject of recent news coverage, with seven articles published across industry, deals, grid, and regulatory categories.
