Power-plant records in South KoreaPrimary fuels in these records
Counts cover 202 records after excluding 14 with non-generating status labels. They are not generation shares. WRI provides the identity backbone; capacities also include GEM and individually cited corrections.
The listed capacity sum combines different reference dates and entity scopes. It is not current national installed capacity. Unknown status does not establish operation.

CO₂ source coverage
Regulator-reported: 0; Climate TRACE estimate: 81; PowerAtlas calculation: 26; Other source value: 0; Not applicable: 70; Not reported: 25.
These categories cover the capacity subset. Source years differ; the figures are not added into a same-year national or owner emissions total.
Highest reported source values
Each bar is a record-level annual source value, not a same-year ranking of current plants. Follow the plant links below for sources and reference periods. Calculated values are counted separately and are not included in this chart.

Frequently asked questions
How many records does this South Korea directory contain?
The directory contains 216 source records. Its capacity subset includes 202 after excluding 14 records with non-generating status labels. Missing status does not confirm operation. This is not a verified current national fleet count.
Which record has the highest listed capacity in this dataset?
Hanbit has the highest listed capacity in this subset: about 6,235 MW. Source dates and unit, station or complex scopes differ; this is not a verified current national ranking.
Which fuels are represented in these records?
Gas is the most frequent primary fuel label in the capacity subset (69 of 202 records). It contains 11 fuel types. Record counts are not electricity-generation shares.
What does the 2025 grid dataset show for South Korea?
The 2025 Ember / Our World in Data snapshot reports about 417 gCO₂/kWh and 40.0% low-carbon generation, rounded as displayed. These national estimates are separate from the plant records.
