OilNew YorkUnited States of America

Oswego Harbor Power is a 1,804 MW oil power station in New York, United States of America. It is operated by NRG Oswego Harbor Power Operations Inc. Based on reported annual generation of 17 GWh, it can supply roughly 4,800 homes. It ranks #99 of 9,833 United States of America power plants by installed capacity. Commissioned in 1977, it is around 49 years old — long-established. 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).

~12,600 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

2,937passenger cars driven for a year
1,643homes' yearly energy use
210,000tree 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 43.5°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 53% 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: 81/100 — 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.
