Wind power plant in Jeju-do, South Korea. Approximate location 33.3416, 126.1661.
WindJeju-doSouth Korea
Hangyeong is a 21 MW wind power plant in Jeju-do, South Korea. Based on its capacity (estimated), it can supply roughly 17,870 homes (estimated). It ranks #154 of 204 South Korea power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, wind supplies about 0.6% of South Korea's electricity; the national grid averages 417 gCO₂/kWh (40.0% low-carbon) (2025).

This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 33.3°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 32% 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: 37/100 — 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.
