WasteOregonUnited States of AmericaCO₂ reported

Covanta Marion Inc is a 13 MW waste power plant in Oregon, United States of America. It is operated by Covanta Marion Inc. Based on reported annual generation of 66 GWh, it can supply roughly 18,857 homes. It ranks #4269 of 9,833 United States of America power plants by installed capacity. Commissioned in 1986, it is around 40 years old — long-established. Its measured emissions of 109,869 t CO₂/yr (Climate TRACE) are equivalent to about 25,610 cars driven for a year. In context, the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

Local climate & thermal context

This waste plant recovers energy by combusting municipal or industrial waste. It sits in a warm-summer Mediterranean climate (Köppen Csb) — Northern Hemisphere, latitude 45.0°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 1% 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: 50/100 — this site sits in the mid 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.
