The Padua Grid BESS Unit 3 is a proposed 201.35 MW battery storage project located in Bexar County, Texas. Developed by Padua Grid, LLC, the project consists entirely of battery storage. It is interconnected within the ERCOT region under queue ID ERCOT-28INR0024, with a queue entry date of March 22, 2024, and a proposed commercial operation date of May 15, 2026. The project's interconnection status is currently in the Facility Study phase.
The proposed project is linked to the existing Padua 3 operating plant (EIA plant ID 68914). The point of interconnection is Tap #5395 O.W Sommer 138kV. The project has appeared in recent news coverage.
