GasIncheonSouth KoreaCO₂ reported

Seoincheon is a 1,800 MW gas power station in Incheon, South Korea. It is operated by Korea Western Power. Based on its capacity (estimated), it can supply roughly 2,027,314 homes (estimated). It ranks #24 of 204 South Korea power plants by installed capacity. Commissioned in 1992, it is around 34 years old — long-established. Its measured emissions of 5,441,800 t CO₂/yr (Climate TRACE) are equivalent to about 1,268,485 cars driven for a year. In context, gas supplies about 27.9% of South Korea's electricity; the national grid averages 417 gCO₂/kWh (40.0% 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 monsoon hot-summer continental climate (Köppen Dwa) — Northern Hemisphere, latitude 37.5°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 17% above 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: 59/100 — 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).
