LAKE CATHERINE, a 752 MW Natural Gas power plant in Hot Spring County, Arkansas. Operated by ENTERGY ARKANSAS INC, commissioned 1970.
How LAKE CATHERINE compares
With 752 MW of capacity, LAKE CATHERINE ranks 5th among the 48 operating power plants Bywatts maps in Arkansas and 2nd of the 15 operating Natural Gas plants in the state. It accounts for about 10% of Arkansas's operating Natural Gas capacity and 4.6% of all operating capacity in the state. Nationally it is the 165th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1970, it is older than 70% of the 48 operating Arkansas plants with a recorded commissioning year. Its operator, ENTERGY ARKANSAS INC, runs 7 operating plants in Arkansas totaling 6,977 MW. It shares Hot Spring County with 3 other operating plants, including MAGNET COVE and HOT SPRING GENERATING FACILITY.
EIA-860 lists 1 generator at the site with 553 MW of nameplate capacity, all natural gas steam turbine technology (this page's HIFLD capacity figure is 752 MW). Net generation was 300 GWh in 2024 (a 6.2% capacity factor).
Grid neighborhood

Weather peril exposure
LAKE CATHERINE is a 752 MW natural gas power plant in Hot Spring County, AR, operated by ENTERGY ARKANSAS INC, commissioned in 1970. Hot Spring County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.3 of 5 at the 82nd national percentile. Lightning is the leading peril, rated Relatively High by FEMA at the 100th 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.
