The Aldrin 345 BESS project is a proposed 362 MW battery storage project located in Brazoria County, Texas. Developed by Aldrin Energy Storage LLC, the project consists entirely of battery storage. It is currently active in the ERCOT interconnection queue as entry ERCOT-25INR0425, with a queue entry date of May 15, 2023.
The proposed commercial operation date for the Aldrin 345 BESS project is December 1, 2027. The project has an executed Interconnection Agreement (IA), with the IA executed on June 15, 2024. The point of interconnection is the Meadow 345kV substation (Bus: 43030).
