Yeong Yang — South Korea

Yeong Yang is a 61.5 MW wind power plant in Gyeongsangbuk-do, South Korea. It is operated by GS E&R Corp [100%]. Based on its capacity (estimated), it can supply roughly 52k homes (estimated). It ranks #145 of 216 South Korea power plants by installed capacity. Commissioned in 2015, it is around 11 years old — relatively modern. 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).

In context: how this plant compares

At 61.5 MW, Yeong Yang is well above the median wind plant in South Korea (30 MW). Technically it is described as Onshore. Wind turbines convert moving air into electricity; output is variable and site-dependent, and modern turbines deliver some of the lowest-cost new generation on many grids.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context

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 36.6°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 16% 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: 59/100 — this site sits in the mid third of the power plants we cover by heating degree-days.

Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.

Site climate & environmental severity

This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness the leading environmental stress.

Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
