Gas power plant in Texas, United States of America. Approximate location 32.8482, -94.548.

GasTexasUnited States of AmericaSteamCO₂ measured

Wilkes is a 882 MW gas power station in Texas, United States of America. It is operated by Southwestern Electric Power Co. Based on reported annual generation of 631 GWh, it can supply roughly 180k homes. It ranks #695 of 10,884 United States of America power plants by installed capacity. Commissioned in 1969, it is around 57 years old — an older, legacy facility. Its annual emissions of 666,062 t CO₂/yr (US EPA GHGRP) are equivalent to about 155k cars driven for a year. In context, gas supplies about 40.0% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

In context: how this plant compares

At 882 MW, Wilkes is well above the median gas plant in United States of America (121.2 MW). Technically it is described as Steam. Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

666,062 t CO₂/yr — in everyday terms

This facility's annual emissions are roughly equivalent to:

12kmillion cubic feet of natural gas burned
155kgasoline cars driven for a year
666kacres of US forest absorbing CO₂ for a year
0.09%of the CO₂ from all United States of America power plants with an emissions figure in PowerAtlas

Equivalencies via US EPA Greenhouse Gas Equivalencies; emissions per US EPA GHGRP (measured for US EPA/EU ETS, modelled for Climate TRACE).

Local climate & thermal context

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 32.8°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 51% below the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 29/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.

A gas turbine here also runs ~2% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).

Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.

Site climate & environmental severity

This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.
