Combined Locks Energy Center

Gas power plant in Wisconsin, United States of America. Approximate location 44.2717, -88.3011.

GasWisconsinUnited States of AmericaCO₂ reported

Combined Locks Energy Center is a 66 MW gas power plant in Wisconsin, United States of America. It is operated by Appleton Coated LLC. Based on reported annual generation of 362 GWh, it can supply roughly 103,571 homes. It ranks #2439 of 9,833 United States of America power plants by installed capacity. Commissioned in 2002, it is around 24 years old — relatively modern. Its measured emissions of 88,851 t CO₂/yr (Climate TRACE) are equivalent to about 20,711 cars driven for a year. In context, gas supplies about 40.0% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

Local climate & thermal context

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 44.3°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 68% 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: 86/100 — 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.

A gas turbine here also runs ~0% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
