Jeffrey Energy Center is a 2,160 MW coal power station in Kansas, United States of America. It is operated by Evergy Kansas Central Inc. Based on reported annual generation of 6,574 GWh, it can supply roughly 1,878,171 homes. It ranks #66 of 9,833 United States of America power plants by installed capacity. Commissioned in 1980, it is around 46 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).

At 2,160 MW, Jeffrey Energy Center is well above the median coal plant in United States of America (642 MW). Technically it is described as Steam. Its current lifecycle status is “announced” — so it is not yet, or no longer, generating at full output. Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 39.3°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 11% 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: 55/100 — this site sits in the mid 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.

Plants like this lose energy through hot boilers, economizers, superheaters, valves and headers. Inzonex makes removable, reusable boiler & economizer insulation that cuts that loss by up to 90% and holds surface temperatures under 45°C, unclipping in seconds for maintenance.
