About

The LeConte Energy Storage project is a proposed 125 MW battery storage project located in Imperial County, California. The project is being developed within the California Independent System Operator (CAISO) region and is interconnected with San Diego Gas & Electric (SDGE). It entered the CAISO queue as queue ID CAISO-1175 on April 30, 2015, and has a proposed commercial operation date of June 1, 2026. An Interconnection Agreement (IA) was executed on March 17, 2020.

The proposed project is linked to the existing LeConte Energy Storage operating plant (EIA plant ID 64701). Recent news coverage has discussed the project's potential impact on the grid and its ongoing development.
