Geismar

Gas power plant in Louisiana, United States of America. Approximate location 30.2, -91.0.

GasLouisianaUnited States of AmericaCO₂ reported

Geismar is a 84 MW gas power plant in Louisiana, United States of America. It is operated by BASF Corporation. Based on reported annual generation of 632 GWh, it can supply roughly 180,485 homes. It ranks #2154 of 9,833 United States of America power plants by installed capacity. Commissioned in 1993, it is around 33 years old — long-established. Its measured emissions of 121,910 t CO₂/yr (Climate TRACE) are equivalent to about 28,417 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 30.2°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 72% 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: 23/100 — 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 ~3% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
