OilVermontUnited States of America

Essex Junction 19 is a 16 MW oil power plant in Vermont, United States of America. It is operated by Green Mountain Power Corp. Based on reported annual generation of 44 GWh, it can supply roughly 12,571 homes. It ranks #4048 of 9,833 United States of America power plants by installed capacity. Commissioned in 1966, it is around 60 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).

~33,000 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

7,692passenger cars driven for a year
4,304homes' yearly energy use
550,000tree seedlings grown 10 years to absorb it

Estimated, not measured: from reported annual generation × 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 44.5°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 72% 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: 87/100 — 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.
