How DOW CHEMICAL TEXAS OPERATION compares
With 678 MW of capacity, DOW CHEMICAL TEXAS OPERATION ranks 52nd among the 307 operating power plants Bywatts maps in Texas and 39th of the 134 operating Natural Gas plants in the state. It accounts for about 1.0% of Texas's operating Natural Gas capacity and 0.6% of all operating capacity in the state. Nationally it is the 212th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1982, it is older than 75% of the 303 operating Texas plants with a recorded commissioning year. Its operator, DOW CHEMICAL CO, runs 2 operating plants in Texas totaling 938 MW. It shares Brazoria County with 7 other operating plants, including SWEENY COGEN FACILITY and OYSTER CREEK UNIT VIII.
EIA-860 lists 6 generators at the site with 603 MW of nameplate capacity, all natural gas fired combined cycle technology (this page's HIFLD capacity figure is 678 MW). Net generation was 1,901 GWh in 2024 (a 36% capacity factor), down 18% from 2022. Its generators came online between 1982 and 1984.
