CoalMarylandUnited States of America

Mt Storm is a 1,681 MW coal power station in Maryland, United States of America. It is operated by Virginia Electric & Power Co. Based on reported annual generation of 4,533 GWh, it can supply roughly 1,295,171 homes. It ranks #129 of 9,833 United States of America power plants by installed capacity. Commissioned in 1968, it is around 58 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).

~4,533,100 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

1,056,667passenger cars driven for a year
591,171homes' yearly energy use
75,551,667tree seedlings grown 10 years to absorb it

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.

Local climate & thermal context

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 39.2°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 34% 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: 71/100 — 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.
