Cogeneration power plant in Idaho, United States of America. Approximate location 42.9084, -112.5294.
CogenerationIdahoUnited States of AmericaCO₂ reported
Simplot Leasing Don Plant is a 16 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 18,771 homes. It ranks #4074 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 15,229 t CO₂/yr (Climate TRACE) are equivalent to about 3,550 cars driven for a year. In context, the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

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.
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.

The #19 largest cogeneration power plant of 34 in United States of America by capacity.
United States of America has 34 cogeneration power plants in this dataset, together about 1,042 MW of capacity.
