It accounts for about 0.6% of Texas's operating Natural Gas capacity and 0.4% of all operating capacity in the state. Nationally it is the 365th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2004, it is newer than 59% of the 303 operating Texas plants with a recorded commissioning year. Its operator, CITY OF SAN ANTONIO - (TX), runs 6 operating plants in Texas totaling 5,341 MW. It shares Bexar County with 9 other operating plants, including J K SPRUCE and V H BRAUNIG.
EIA-860 lists 4 generators at the site with 230 MW of nameplate capacity, all natural gas fired combustion turbine technology (this page's HIFLD capacity figure is 418 MW). Net generation was 228 GWh in 2024 (an 11% capacity factor), up 57% from 2022.

Weather peril exposure
LEON CREEK is a 418 MW natural gas power plant in Bexar County, TX, operated by CITY OF SAN ANTONIO - (TX), commissioned in 2004. Bexar County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.8 of 5 at the 95th national percentile. Hail is the leading peril, rated Very High by FEMA at the 96th 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.
