How THOMAS C FERGUSON compares
With 446 MW of capacity, THOMAS C FERGUSON ranks 83rd among the 307 operating power plants Bywatts maps in Texas and 68th of the 134 operating Natural Gas plants in the state. It accounts for about 0.7% of Texas's operating Natural Gas capacity and 0.4% of all operating capacity in the state. Nationally it is the 354th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2014, it is newer than 96% of the 303 operating Texas plants with a recorded commissioning year. Its operator, LOWER COLORADO RIVER AUTHORITY, runs 11 operating plants in Texas totaling 3,912 MW. It shares Llano County with one other operating plant, BUCHANAN.
EIA-860 lists 3 generators at the site with 575 MW of nameplate capacity, all natural gas fired combined cycle technology (this page's HIFLD capacity figure is 446 MW). Net generation was 3,612 GWh in 2024 (a 72% capacity factor), up 15% from 2022.

Weather peril exposure
THOMAS C FERGUSON is a 446 MW natural gas power plant in Llano County, TX, operated by LOWER COLORADO RIVER AUTHORITY, commissioned in 2014. Llano County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.0 of 5 at the 76th national percentile. Riverine flooding is the leading peril, rated Relatively Moderate by FEMA at the 92nd 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.
Llano County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Riverine flooding | Relatively Moderate | 92nd | 4.7 of 5 | 2.4 |
| Hail | Relatively Moderate | 81st | 4.2 of 5 | 3.8 |
| Wildfire | Relatively Low | 65th | 3.6 of 5 | <0.01 |
| Winter weather | Relatively Moderate | 61st | 3.5 of 5 | 4.1 |
| Strong wind | Relatively Low | 58th | 3.3 of 5 | 1.1 |
| Hurricane | Very Low | 53rd | 3.1 of 5 | 0.01 |
| Tornado | Relatively Moderate | 49th | 3.0 of 5 | 0.34 |
| Heat wave | Relatively Low | 35th | 2.4 of 5 | 6.7 |
| Ice storm | Very Low | 11th | 1.4 of 5 | 0.46 |
| Lightning | Relatively Moderate | 7th | 1.3 of 5 | 47.9 |
