CogenerationColoradoUnited States of America
Williams Ignacio Natural Gas Plant is a 6 MW cogeneration power plant in Colorado, United States of America. It is operated by Harvest Midstream Co. Based on reported annual generation of 44 GWh, it can supply roughly 12k homes. It ranks #6418 of 10,938 United States of America power plants by installed capacity. Commissioned in 1985, it is around 41 years old — long-established. In context, the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

This cogeneration plant produces electricity and useful heat together for higher fuel efficiency. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 37.1°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 49% above 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: 79/100 — this site sits in the top third of the power plants we cover by heating degree-days.
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.
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 mild atmospheric environment (estimated ISO 9223 class C2 — Low), with thermal cycling 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.
The #26 largest cogeneration power plant of 34 in United States of America by capacity.
United States of America has 34 cogeneration power plants in this dataset, together about 1,037 MW of capacity.
