The Shoshana Storage project is a proposed 221 MW battery energy storage system located in Matagorda County, Texas. The project, developed by Shoshana Storage Project LLC, is interconnected within the ERCOT region under queue ID ERCOT-23INR0466. It entered the interconnection queue on March 30, 2022, and has a proposed commercial operation date of May 30, 2028. The project's interconnection status is currently in the Facility Study phase.
The proposed project consists of 221 MW of battery storage capacity. It is planned to connect to the grid at the Tap STP _x0013_ Refuge ckt 27 point of interconnection. The Shoshana Storage project has been featured in recent news coverage regarding energy storage development in Texas.
