CoalMaineUnited States of America

Schiller is a 171 MW coal power station in Maine, United States of America. It is operated by Granite Shore Power. Based on reported annual generation of 264 GWh, it can supply roughly 75,399 homes. It ranks #1400 of 9,833 United States of America power plants by installed capacity. Commissioned in 1956, it is around 70 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).

~263,900 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

61,515passenger cars driven for a year
34,416homes' yearly energy use
4,398,333tree 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 warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 43.1°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 44% 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: 77/100 — 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.
