OilIowaUnited States of America
Shenandoah is a 20 MW oil power plant in Iowa, United States of America. It is operated by MidAmerican Energy Co. Based on reported annual generation of 0 GWh, it can supply roughly 142 homes. It ranks #3794 of 9,833 United States of America power plants by installed capacity. Commissioned in 2000, it is around 26 years old — long-established. In context, oil supplies about 0.7% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

This facility's annual emissions are roughly equivalent to:
Estimated, not measured: from reported annual generation × a typical oil emission factor (~750 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a hot-summer humid continental climate (Köppen Dfa) — Northern Hemisphere, latitude 40.8°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 32% 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: 69/100 — this site sits in the top third of the power plants we cover by heating degree-days.
In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.
