About

The Riverwalk BESS project is a proposed 120 MW battery storage project located in Bexar County, Texas. Developed by RWE Solar Development, LLC, the project is currently active in the ERCOT interconnection queue as entry ERCOT-24INR0392, with a queue entry date of July 18, 2022. The proposed commercial operation date is October 1, 2027, and the project's interconnection status is currently in the Facility Study phase.

The Riverwalk BESS project is designed as a standalone storage facility, consisting entirely of 120 MW of battery capacity. The point of interconnection is the 5294 Martinez Substation at 138kV. The project has appeared in recent news coverage regarding energy storage developments in Texas.
