About

The proposed OBERON project is a 1036.8 MW hybrid solar and battery energy storage development in Riverside County, California. The project consists of 518.4 MW of solar generation and 518.4 MW of battery storage. It is located within the CAISO region and interconnects to Southern California Edison (SCE) at the Red Bluff Substation 500kV.

OBERON entered the CAISO interconnection queue as queue ID CAISO-1642 on April 15, 2019, with a proposed commercial operation date of April 15, 2026. An Interconnection Agreement (IA) was executed on April 27, 2021, and the project currently has an active interconnection status. The project has been the subject of recent news coverage.
