Cottonwood Energy Project

Gas power plant in Texas, United States of America. Approximate location 30.2588, -93.7353.

GasTexasUnited States of AmericaCO₂ measured

Cottonwood Energy Project is a 1,432 MW gas power station in Texas, United States of America. It is operated by Cottonwood Energy Co LP. Based on reported annual generation of 7,247 GWh, it can supply roughly 2.1 million homes. It ranks #399 of 10,938 United States of America power plants by installed capacity. Commissioned in 2003, it is around 23 years old — relatively modern. Its annual emissions of 2,384,098 t CO₂/yr (US EPA GHGRP) are equivalent to about 556k 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 1,432 MW, Cottonwood Energy Project is well above the median gas plant in United States of America (121 MW). 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.

2,384,098 t CO₂/yr — in everyday terms

This facility's annual emissions are roughly equivalent to:

556kpassenger cars driven for a year
311khomes' yearly energy use
40 milliontree seedlings grown 10 years to absorb it

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 30.3°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 69% 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: 24/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.

A gas turbine here also runs ~3% 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

For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness the leading environmental stress.

Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.

Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
