GasLouisianaUnited States of AmericaCO₂ reported

Nine Mile Point is a 2,440 MW gas power station in Louisiana, United States of America. It is operated by Entergy Louisiana LLC. Based on reported annual generation of 9,832 GWh, it can supply roughly 2,809,285 homes. It ranks #41 of 9,833 United States of America power plants by installed capacity. Commissioned in 1983, it is around 43 years old — long-established. Its measured emissions of 4,233,330 t CO₂/yr (Climate TRACE) are equivalent to about 986,790 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 29.9°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 77% 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: 21/100 — this site sits in the bottom 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 ~4% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
