sourceThe SOLEIL CANTIL project is a proposed 597.3 MW hybrid solar and battery energy storage project located in Kern County, California. The development project, consisting of 372.3 MW of solar capacity and 225 MW of battery storage, is interconnected to the CAISO grid at the Windhub Substation 500kV.
The project is listed in the CAISO interconnection queue as queue ID CAISO-2078, with an entry date of April 15, 2021. The proposed commercial operation date is February 26, 2033. The project's interconnection status is currently in the System Impact Study phase.
