GasOklahomaUnited States of AmericaCO₂ reported

Stillwater Energy Center is a 56 MW gas power plant in Oklahoma, United States of America. It is operated by Stillwater Utilities Authority. Based on reported annual generation of 44 GWh, it can supply roughly 12,600 homes. It ranks #2601 of 9,833 United States of America power plants by installed capacity. Commissioned in 2016, it is around 10 years old — relatively modern. Its measured emissions of 81,954 t CO₂/yr (Climate TRACE) are equivalent to about 19,103 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 humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 36.2°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 22% below 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: 42/100 — 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.

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