Covanta Hempstead is a 79 MW waste power plant in New York, United States of America. It is operated by Covanta Hempstead Company. Based on reported annual generation of 542 GWh, it can supply roughly 155k homes. It ranks #3161 of 10,938 United States of America power plants by installed capacity. Commissioned in 1989, it is around 37 years old — long-established. Its modelled annual emissions are 659,190 t CO₂/yr (Climate TRACE), equivalent to about 154k cars driven for a year. In context, the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

At 79 MW, Covanta Hempstead is well above the median waste plant in United States of America (7 MW). Waste-to-energy plants burn municipal solid waste to generate electricity and heat, cutting landfill volume while recovering energy from residual waste.

This waste plant recovers energy by combusting municipal or industrial waste. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 40.7°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 8% 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: 54/100 — 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.
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
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.
The #20 largest waste power plant of 551 in United States of America by capacity.
United States of America has 551 waste power plants in this dataset, together about 10,154 MW of capacity.
