HARRISON COUNTY POWER PROJECT, a 570 MW Natural Gas power plant in Harrison County, Texas. Operated by ENTERGY POWER VENTURES LP, commissioned 2003.
How HARRISON COUNTY POWER PROJECT compares
With 570 MW of capacity, HARRISON COUNTY POWER PROJECT ranks 67th among the 307 operating power plants Bywatts maps in Texas and 52nd of the 134 operating Natural Gas plants in the state. It accounts for about 0.8% of Texas's operating Natural Gas capacity and 0.5% of all operating capacity in the state. Nationally it is the 281st-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2003, it is newer than 56% of the 303 operating Texas plants with a recorded commissioning year. It shares Harrison County with 3 other operating plants, including EASTMAN COGENERATION FACILITY and SNIDER INDUSTRIES.
EIA-860 lists 3 generators at the site with 570 MW of nameplate capacity, all natural gas fired combined cycle technology. Net generation was 3,248 GWh in 2024 (a 65% capacity factor), up 18% from 2022.

Weather peril exposure
HARRISON COUNTY POWER PROJECT is a 570 MW natural gas power plant in Harrison County, TX, operated by ENTERGY POWER VENTURES LP, commissioned in 2003. Harrison County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.2 of 5 at the 79th national percentile. Ice storm is the leading peril, rated Very High by FEMA at the 94th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a natural gas plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
