The Shoals Energy Storage project is a proposed 409 MW battery storage development in Ventura County, California. The project, under consideration in the CAISO interconnection queue (queue ID CAISO-1783), is being evaluated for connection to the Mandalay Switchyard 220kV. The queue entry date is April 15, 2020, with a proposed commercial operation date of October 8, 2030. The project's interconnection status is currently in the System Impact Study phase.
The Shoals Energy Storage project has been mentioned in recent industry news.
