OilMaineUnited States of America

Caribou Generation Station is a 27 MW oil power plant in Maine, United States of America. It is operated by Merlin One LLC. Based on its capacity (estimated), it can supply roughly 20,573 homes (estimated). It ranks #3372 of 9,833 United States of America power plants by installed capacity. Commissioned in 1950, it is around 76 years old — an older, legacy facility. 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).

~54,005 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

12,589passenger cars driven for a year
7,043homes' yearly energy use
900,090tree seedlings grown 10 years to absorb it

Estimated, not measured: from installed capacity at a typical 30% load factor × 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.

Local climate & thermal context

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 46.8°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 111% 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: 95/100 — 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.
