Coal power plant in Jeollanam-do, South Korea. Approximate location 34.8545, 127.7351.
CoalJeollanam-doSouth Korea
Honam is a 500 MW coal power station in Jeollanam-do, South Korea. It is operated by Korea East West Power. Based on its capacity (estimated), it can supply roughly 625,714 homes (estimated). It ranks #66 of 204 South Korea power plants by installed capacity. Commissioned in 1973, it is around 53 years old — an older, legacy facility. In context, coal supplies about 31.1% 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 50% load factor × a typical coal emission factor (~1000 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. 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.

The #14 largest coal power plant of 29 in South Korea by capacity.
South Korea has 29 coal power plants in this dataset, together about 39,821 MW of capacity.
