Cogeneration power plant in Idaho, United States of America. Approximate location 42.9084, -112.5294.
CogenerationIdahoUnited States of AmericaCO₂ modelled
Simplot Leasing Don Plant is a 15.9 MW cogeneration power plant in Idaho, United States of America. It is operated by Simplot Leasing Corp. Based on reported annual generation of 66 GWh, it can supply roughly 19k homes. It ranks #5079 of 10,884 United States of America power plants by installed capacity. Commissioned in 1986, it is around 40 years old — long-established. Its modelled annual emissions are 15,229 t CO₂/yr (Climate TRACE), equivalent to about 3.5k cars driven for a year. In context, the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

Local climate & thermal context
This cogeneration plant produces electricity and useful heat together for higher fuel efficiency. It sits in a cold semi-arid steppe climate (Köppen BSk) — Northern Hemisphere, latitude 42.9°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 80% 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: 90/100 — this site sits in the top 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 benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with dust abrasion 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.
