How GRAHAM compares
With 635 MW of capacity, GRAHAM ranks 59th among the 307 operating power plants Bywatts maps in Texas and 45th of the 134 operating Natural Gas plants in the state. It accounts for about 0.9% of Texas's operating Natural Gas capacity and 0.6% of all operating capacity in the state. Nationally it is the 240th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1960, it is older than 91% of the 303 operating Texas plants with a recorded commissioning year. Its operator, LUMINANT GENERATION COMPANY LLC, runs 9 operating plants in Texas totaling 9,469 MW. It shares Young County with one other operating plant, TRINITY HILLS.
EIA-860 lists 2 generators at the site with 635 MW of nameplate capacity, all natural gas steam turbine technology. Net generation was 1,042 GWh in 2024 (a 19% capacity factor). Its generators came online between 1960 and 1969.
