Gas power plant in Iowa, United States of America. Approximate location 41.6572, -91.54.

GasIowaUnited States of AmericaCO₂ modelled

University of Iowa Main Power Plant is a 30.7 MW gas power plant in Iowa, United States of America. It is operated by University of Iowa. Based on reported annual generation of 55 GWh, it can supply roughly 16k homes. It ranks #4209 of 10,884 United States of America power plants by installed capacity. Commissioned in 1981, it is around 45 years old — long-established. Its modelled annual emissions are 62,772 t CO₂/yr (Climate TRACE), equivalent to about 15k 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 30.7 MW, University of Iowa Main Power Plant is below the median gas plant in United States of America (121.2 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.

~62,772 t CO₂/yr (modelled) — in everyday terms

This facility's annual emissions are roughly equivalent to:

1.1kmillion cubic feet of natural gas burned
13khomes' electricity use for a year
63kacres of US forest absorbing CO₂ for a year

Equivalencies via US EPA Greenhouse Gas Equivalencies; modelled emissions from 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 hot-summer humid continental climate (Köppen Dfa) — Northern Hemisphere, latitude 41.7°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 38% 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: 73/100 — this site sits in the top third of the power plants we cover by heating degree-days.

A gas turbine here also runs ~0% 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 mild atmospheric environment (estimated ISO 9223 class C2 — Low), with thermal cycling the leading environmental stress.
