About

The Golden Fields Solar project is a proposed 100 MW battery storage project located in Kern County, California. The project is in the California Independent System Operator (CAISO) interconnection queue as queue ID CAISO-1212, with an original queue entry date of April 30, 2015. The proposed commercial operation date is December 1, 2026. The project has an Interconnection Agreement (IA) executed as of December 6, 2019.

The project is interconnected to the Southern California Edison (SCE) utility grid at the Whirlwind Substation 230kV. Golden Fields Solar has been the subject of recent news coverage, with three articles categorized as regulatory matters.
