About

Big Watt Power Austin-1 is a proposed 448.98 MW gas-fired combined-cycle generation project located in Caldwell County, Texas. The project, developed by Big Watt Power Austin-1 LLC, is in the ERCOT interconnection queue as entry ERCOT-29INR0167, with a queue entry date of October 3, 2025. Its proposed commercial operation date is November 1, 2028. The point of interconnection is planned for tapping the 345 kV double circuit line between Zorn (Bus# 7042) and Lytton Springs (Bus# 9074), and between Zorn (Bus# 7042) and Austrop (Bus# 7040).

The project currently has an active status in the interconnection queue and has been mentioned in recent industry news.
