The Fallbrook Energy Storage project is a proposed 69.6 MW battery storage project located in San Diego County, California. Interconnecting to the CAISO grid via the Avocado Substation 69 kV point of interconnection, the project entered the CAISO queue as queue ID CAISO-1169 on April 30, 2015. The proposed commercial operation date is March 6, 2026, and the interconnection agreement has been executed.
The development project is linked to the existing Fallbrook Energy Storage operating plant (EIA ID 61365). Recent news coverage indicates interest in the project, with articles focusing on grid applications and industry developments.
