The W.A. Parish Generating Station is a 3.65-gigawatt (3,653 MW), dual-fired power plant located near Thompsons, Texas. The station occupies a 4,664-acre site near Smithers Lake southwest of Houston in Fort Bend County and consists of two four-unit plants; one natural gas and the other coal (2,697 MW).[1] With a total installed capacity of 3,653 MW, it is the second largest conventional power station in the US.[2] NRG Energy owns and operates the plant.[1]

The multiple coal mines supply three 124-car trainloads worth of low-sulfur coal to units 5-8 or 36,000 tons daily.

Completed in January 2017, the post-combustion[3] Petra Nova Carbon Capture Project became largest installed on an existing power plant in the world.[4][5] The system pumps 1.6 million tons of filtered carbon dioxide (CO2) from unit 8 to the West Ranch Oil Field 82 miles away in Jackson County.[6][7] Overall as the system is powered by natural gas it will have a net effect of not releasing 785,000 tons of carbon annually.[8] The system cost approximately $1 billion.[9]

Adjacent to Parish Station is the natural gas Brazos Valley Power Plant owned by Calpine Energy which opened in 2003.[10]

During the 2021 Texas power crisis, Parish Station was reported to have experienced up to a 664 MW loss in generation capacity, including an 80 MW decrease in capacity early in the crisis that contributed to the need for rolling blackouts.[11]
