Gas power plant in Jeollanam-do, South Korea. Approximate location 34.9073, 127.7449.
GasJeollanam-doSouth Korea
Gwangyang POSCO is a 500 MW gas power station in Jeollanam-do, South Korea. It is operated by POSCO. Based on its capacity (estimated), it can supply roughly 563,142 homes (estimated). It ranks #65 of 204 South Korea power plants by installed capacity. Commissioned in 2000, it is around 26 years old — long-established. In context, gas supplies about 27.9% of South Korea's electricity; the national grid averages 417 gCO₂/kWh (40.0% low-carbon) (2025).

This facility's annual emissions are roughly equivalent to:
Estimated, not measured: from installed capacity at a typical 45% load factor × 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.

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a humid subtropical (dry winter) climate (Köppen Cwa) — Northern Hemisphere, latitude 34.9°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 11% 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: 46/100 — 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).

The #28 largest gas power plant of 46 in South Korea by capacity.
South Korea has 46 gas power plants in this dataset, together about 38,423 MW of capacity.
