Boryeong (poryang)

Boryeong (poryang) is a 4,000 MW coal power station in Chungcheongnam-do, South Korea. It is operated by Korea Midland Power (KOMIPO). Based on its capacity (estimated), it can supply roughly 5,005,714 homes (estimated). It ranks #4 of 204 South Korea power plants by installed capacity. Its measured emissions of 15,442,000 t CO₂/yr (Climate TRACE) are equivalent to about 3,599,534 cars driven for a year. In context, coal supplies about 31.1% of South Korea's electricity; the national grid averages 417 gCO₂/kWh (40.0% low-carbon) (2025).

Local climate & thermal context

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 36.4°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 10% 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: 55/100 — 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.
