Sejong

Hydro power plant in Daejeon, South Korea. Approximate location 36.4727, 127.26.

HydroDaejeonSouth KoreaCO₂ reported

Sejong is a 2 MW hydro power plant in Daejeon, South Korea. It is operated by Korea Water Resources Corporation. Based on its capacity (estimated), it can supply roughly 2,302 homes (estimated). It ranks #194 of 204 South Korea power plants by installed capacity. Its measured emissions of 660,810 t CO₂/yr (Climate TRACE) are equivalent to about 154,035 cars driven for a year. In context, hydro supplies about 0.6% of South Korea's electricity; the national grid averages 417 gCO₂/kWh (40.0% low-carbon) (2025).

Local climate & thermal context

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a hot-summer humid continental climate (Köppen Dfa) — Northern Hemisphere, latitude 36.5°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 12% 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: 56/100 — 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.
