Red Holly Storage is a proposed 50 MW battery storage project located in Dawson County, Texas. Developed by GreenGo Energy, the project is interconnected within the ERCOT region under queue ID ERCOT-21INR0033. The project entered the interconnection queue on September 27, 2018, and has a proposed commercial operation date of May 30, 2028. The Interconnection Agreement (IA) for the project was executed on October 19, 2020.
The project consists of 50 MW of battery storage capacity. The point of interconnection (POI) is at the tap 345kV 59900 Longdraw - 79641 Farmland. The Red Holly Storage project has been mentioned in recent news coverage related to the energy industry.
