CoalUtahUnited States of America

Bonanza is a 500 MW coal power station in Utah, United States of America. It is operated by Deseret Generation & Tran Coop. Based on reported annual generation of 3,738 GWh, it can supply roughly 1,067,971 homes. It ranks #735 of 9,833 United States of America power plants by installed capacity. Commissioned in 1986, it is around 40 years old — long-established. In context, coal supplies about 16.3% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

Local climate & thermal context

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a cold semi-arid steppe climate (Köppen BSk) — Northern Hemisphere, latitude 40.1°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 49% 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: 79/100 — 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.
