Regional Waste Systems

Waste power plant in Maine, United States of America. Approximate location 43.6556, -70.3347.

WasteMaineUnited States of AmericaCO₂ reported

Regional Waste Systems is a 13 MW waste power plant in Maine, United States of America. It is operated by Ecomaine. Based on reported annual generation of 79 GWh, it can supply roughly 22,685 homes. It ranks #4260 of 9,833 United States of America power plants by installed capacity. Commissioned in 1988, it is around 38 years old — long-established. Its measured emissions of 111,546 t CO₂/yr (Climate TRACE) are equivalent to about 26,001 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 humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 43.7°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 54% 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.
