HydroChungcheongbuk-doSouth Korea

Goesan is a 3 MW hydro power plant in Chungcheongbuk-do, South Korea. It is operated by Korea Hydro and Nuclear. Based on its capacity (estimated), it can supply roughly 2,803 homes (estimated). It ranks #192 of 204 South Korea power plants by installed capacity. Commissioned in 1957, it is around 69 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. 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 monsoon hot-summer continental climate (Köppen Dwa) — Northern Hemisphere, latitude 36.8°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 31% 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: 69/100 — this site sits in the top 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.
