The Elion Energy Storage project is a proposed 302.4 MW battery storage project located in Los Angeles County, California. Interconnection is being sought through the CAISO queue, with queue ID CAISO-2064. The project entered the queue on April 15, 2021, and has a proposed commercial operation date of May 26, 2034. Its interconnection status is currently in the System Impact Study phase.
The project is interconnected with Southern California Edison (SCE) at the Antelope Valley Substation 230 kV point of interconnection. Recent news coverage indicates activity related to the project, with five articles appearing, primarily focused on deals and grid-related topics.
