sourceThe Calypso Solar project is a proposed 800 MW hybrid solar and battery energy storage development in Riverside County, California. The project consists of 400 MW of solar photovoltaic generation paired with 400 MW of battery storage. It is located within the California Independent System Operator (CAISO) region and interconnects to Southern California Edison (SCE) at the Colorado River Substation 230kV.
The project, identified as CAISO-1636 in the interconnection queue, entered the queue on April 15, 2019, and has a proposed commercial operation date of October 28, 2031. The interconnection agreement (IA) for the project has been executed. The project has appeared in recent news coverage.
