The proposed NRG THW GT 345 (TEF -Due Diligence) project is a 456 MW gas-fired generation project located in Harris County, Texas. The developer is NRG THW GT LLC. It is interconnected within the ERCOT region under queue ID ERCOT-24INR0482, with a queue entry date of November 17, 2022, and a proposed commercial operation date of May 1, 2026. The project's interconnection agreement has been executed as of August 22, 2024.
This development project is linked to the existing NRG THW GT Electric Generating Station, EIA plant ID 66601. The point of interconnection is the 345 kV Bus Number 45500, Bus Name T_H_W__POI_5. The project is currently listed as active in the ERCOT interconnection queue.
