About

The proposed MARICI project is a 405.51 MW battery storage development in Los Angeles County, California. It is located within the CAISO region and interconnects with Southern California Edison (SCE) at the Walnut Substation 230 kV. The project entered the CAISO interconnection queue as queue ID CAISO-2116 on April 15, 2021, and has a proposed commercial operation date of February 26, 2031. Its interconnection status is currently in the System Impact Study phase.

The MARICI project is being tracked in recent news coverage.
