Austin Bayou Solar is a proposed solar generation project located in Brazoria County, Texas, with a total capacity of 753.4 MW. Developed by Austin Bayou Solar, LLC, the project consists entirely of solar photovoltaic generation. It is currently in the ERCOT interconnection queue as entry ERCOT-25INR0102, with a queue entry date of June 27, 2022, and a proposed commercial operation date of June 1, 2027.
The project's Interconnection Agreement (IA) has been executed as of November 15, 2023. The point of interconnection is at the Tap 345kV 42500 DOW CHEMICAL - 43035 OASIS CKT#27. The Austin Bayou Solar project has been the subject of recent news coverage.
