MacArthur Waste to Energy Facility — United States of America

MacArthur Waste to Energy Facility is a 12.5 MW waste power plant in New York, United States of America. It is operated by Covanta MacArthur Renewable Energy. Based on reported annual generation of 50 GWh, it can supply roughly 14k homes. It ranks #5334 of 10,884 United States of America power plants by installed capacity. Commissioned in 1990, it is around 36 years old — long-established. Its modelled annual emissions are 104,831 t CO₂/yr (Climate TRACE), equivalent to about 24k 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 humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 40.8°N — which shapes how much energy it can produce and how its output varies through the year.

Monthly mean temperature

Heating degree-days here run 15% 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: 58/100 — this site sits in the mid third of the power plants we cover by heating degree-days.

Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.

Site climate & environmental severity

This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with marine corrosion the leading environmental stress.

Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
