The Hidden Valley BESS is a proposed 9.9 MW battery storage project located in Harris County, Texas. Developed by Regis Hidden Valley, LLC, the project is interconnected within the ERCOT region under queue ID ERCOT-24INR0594. The proposed commercial operation date is April 15, 2025.
The project's Interconnection Agreement (IA) has been executed as of September 20, 2023. The point of interconnection (POI) is at the Hidden Valley substation (TSP Station Code HV) at transformer TR4, bus number 45862, operating at 138 kV.
