CoalPennsylvaniaUnited States of America

Conemaugh is a 1,963 MW coal power station in Pennsylvania, United States of America. It is operated by KeyCon Operating LLC. Based on reported annual generation of 11,006 GWh, it can supply roughly 3,144,457 homes. It ranks #79 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).

Local climate & thermal context

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 40.4°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.

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.
