GridStor acquired 150MW/300MWh Brazoria County BESS project from Balanced Rock Power
sourceThe Desna BESS project is a proposed 205.46 MW battery storage project located in Brazoria County, Texas. Developed by BRP Desna BESS LLC, the project is interconnected within the ERCOT region under queue ID ERCOT-24INR0128. The project entered the interconnection queue on December 15, 2021, and has a proposed commercial operation date of May 6, 2026.
The project's Interconnection Agreement (IA) has been executed as of September 15, 2023. The Desna BESS project is linked to the existing Desna operating plant (EIA ID 65876). The point of interconnection is the 39703 TNP FM524 138kV. The project has appeared in recent news coverage.
