TOLK, a 1,136 MW Coal power plant in Lamb County, Texas. Operated by SOUTHWESTERN PUBLIC SERVICE CO, commissioned 1982.
How TOLK compares
With 1,136 MW of capacity, TOLK ranks 20th among the 307 operating power plants Bywatts maps in Texas and 8th of the 12 operating Coal plants in the state. It accounts for about 6.2% of Texas's operating Coal capacity and 1.1% of all operating capacity in the state. Nationally it is the 102nd-largest of the 324 operating Coal plants in the database. Commissioned in 1982, it is older than 75% of the 303 operating Texas plants with a recorded commissioning year. Its operator, SOUTHWESTERN PUBLIC SERVICE CO, runs 5 operating plants in Texas totaling 3,559 MW. It shares Lamb County with one other operating plant, PLANT X.
EIA-860 lists 2 generators at the site with 1,136 MW of nameplate capacity, all conventional steam coal technology. Net generation was 1,974 GWh in 2024 (a 20% capacity factor), down 24% from 2022. Its generators came online between 1982 and 1985.

Weather peril exposure
TOLK is a 1,136 MW coal power plant in Lamb County, TX, operated by SOUTHWESTERN PUBLIC SERVICE CO, commissioned in 1982. Lamb County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.9 of 5 at the 98th national percentile. Hail is the leading peril, rated Relatively High by FEMA at the 99th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a coal plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
Lamb County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Hail | Relatively High | 99th | 4.9 of 5 | 5.3 |
