Gas power plant in Gyeonggi-do, South Korea. Approximate location 37.3615, 127.6582.
GasGyeonggi-doSouth KoreaCO₂ modelled
Yeoju Complex power station is a 1,000 MW gas power station in Gyeonggi-do, South Korea. It is operated by Yeoju Energy Service Co Ltd. Based on its capacity (estimated), it can supply roughly 1.1 million homes (estimated). It ranks #43 of 216 South Korea power plants by installed capacity. Its modelled annual emissions are 1,729,500 t CO₂/yr (Climate TRACE), equivalent to about 403k 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).

In context: how this plant compares
At 1,000 MW, Yeoju Complex power station is well above the median gas plant in South Korea (515 MW). Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.

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 37.4°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 25% 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: 65/100 — this site sits in the mid third of the power plants we cover by heating degree-days.
A gas turbine here also runs ~0% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.
Site climate & environmental severity
This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with thermal cycling the leading environmental stress.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
