GREC

Gas power plant in Oklahoma, United States of America. Approximate location 36.1903, -95.2894.

GasOklahomaUnited States of AmericaCO₂ reported

GREC is a 1,734 MW gas power station in Oklahoma, United States of America. It is operated by Grand River Dam Authority. Based on reported annual generation of 2,206 GWh, it can supply roughly 630,200 homes. It ranks #114 of 9,833 United States of America power plants by installed capacity. Commissioned in 1995, it is around 31 years old — long-established. Its measured emissions of 2,520,700 t CO₂/yr (Climate TRACE) are equivalent to about 587,576 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 23% 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: 41/100 — 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).
