Across the 83 South Korea power plants carrying an asset-level CO₂ figure in this open dataset, total emissions are about 229 Mt CO₂/yr. The single largest emitter, Taean (coal), accounts for about 13% of that 83-plant reported subset (not of the whole country). The top three owners — Korea Western Power, Korea Southern Power, Korea South East Power (KOSEP) — control roughly 44% of that 83-plant reported subset. Most of these plants sit in a temperate Köppen climate zone.

There are 216 power plants in South Korea in this open dataset, with about 147,246 MW of total capacity.
Hanbit is the largest at about 6,235 MW (nuclear).
The most common plant type in this dataset is gas (77 plants), across 11 fuel types in total.
South Korea's grid carbon intensity is about 417 gCO₂/kWh, with 40.0% low-carbon generation (<a href="https://ember-energy.org/" rel="nofollow">Ember</a> / <a href="https://ourworldindata.org/energy" rel="nofollow">Our World in Data</a> (CC BY 4.0)).
