Juanita Creek BESS is a proposed 303.6 MW hybrid battery energy storage project in Matagorda County, Texas. Developed by Juanita Creek Energy Center, LLC, the project consists of battery energy storage and other unspecified technologies. It is currently active in the ERCOT interconnection queue as entry ERCOT-29INR0151, with a queue entry date of June 19, 2025, and a proposed commercial operation date of October 1, 2031.
The point of interconnection for Juanita Creek BESS is planned at Tap CKT #39 between El Maton (#43990) and W.A.Parish (#44000).
