Cardinal is a 1,880 MW coal power station in Ohio, United States of America. It is operated by Cardinal Operating Company. Based on reported annual generation of 9,640 GWh, it can supply roughly 2,754,342 homes. It ranks #90 of 9,833 United States of America power plants by installed capacity. Commissioned in 1970, it is around 56 years old — an older, legacy facility. In context, coal supplies about 16.3% 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 coal emission factor (~1000 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 40.3°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 22% 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: 63/100 — this site sits in the mid 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.

The #35 largest coal power plant of 286 in United States of America by capacity.
United States of America has 286 coal power plants in this dataset, together about 249,149 MW of capacity.
