PLANT X, a partly retired 434 MW Natural Gas power plant in Lamb County, Texas. Most of its capacity was retired, most recently in 2023, according to EIA-860.
How PLANT X compares
EIA-860 lists 190 MW still operable at the site (natural gas steam turbine), against the 434 MW recorded for it. 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, TOLK.
EIA-860 lists 1 generator at the site with 190 MW of nameplate capacity, all natural gas steam turbine technology (this page's HIFLD capacity figure is 434 MW). Net generation was 816 GWh in 2024 (a 49% capacity factor), up 62% from 2022.
Grid neighborhood
The closest transmission line found within 10 miles is a 230 kV line owned by SOUTHWESTERN PUBLIC SERVICE CO., under 0.1 miles away. One other operating power plant sits within 25 miles: TOLK (1,136 MW, Coal).

Weather peril exposure
PLANT X is a partly retired 434 MW natural gas power plant in Lamb County, TX, operated by SOUTHWESTERN PUBLIC SERVICE CO. 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 natural gas 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 |
| Winter weather | Relatively Moderate | 88th | 4.5 of 5 | 8.2 |
| Wildfire | Relatively Low | 88th | 4.5 of 5 | <0.01 |
| Tornado | Relatively Low | 83rd | 4.3 of 5 | 0.77 |
| Strong wind | Relatively High | 82nd | 4.3 of 5 | 2.4 |
| Lightning | Relatively Low | 56th | 3.3 of 5 | 47.8 |
| Heat wave | Very Low | 52nd | 3.1 of 5 | 1.5 |
| Ice storm | Relatively Low | 49th | 3.0 of 5 | 0.48 |
| Hurricane | Very Low | 26th | 2.0 of 5 | <0.01 |
| Earthquake | Very Low | 26th | 2.0 of 5 | <0.01 |

Perils not assessed in Lamb County
These perils carry no usable National Risk Index figure for this county, so they are excluded from the scoring rather than scored zero. A zero would claim the peril was assessed and found benign.
