GasGeorgiaUnited States of America

Effingham County Power Project is a 597 MW gas power station in Georgia, United States of America. It is operated by SEPG Operating Services LLC Effingham. Based on reported annual generation of 2,135 GWh, it can supply roughly 610,000 homes. It ranks #630 of 9,833 United States of America power plants by installed capacity. Commissioned in 2003, it is around 23 years old — relatively modern. 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).

~854,000 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

199,068passenger cars driven for a year
111,372homes' yearly energy use
14,233,333tree seedlings grown 10 years to absorb it

Estimated, not measured: from reported annual generation × a typical gas emission factor (~400 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

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 32.3°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 64% 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: 25/100 — 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).
