Records by technology

Counts records, not generation share · coverage & dates

Reported capacity is the rated size of the listed installations, not electricity being produced now. Source dates and coverage differ, so newer facilities may be absent and historical records may remain.

How electricity works in South Korea

Single buyerOne state buyer, private generators

Nuclear, coal and gas supply power. Generators sell into a cost-based pool run by KPX.

  1. GenerationState utility + private producers
  2. TransmissionOne state buyer
  3. DistributionUtility networks
  4. CustomersRegulated tariffs

Who regulates

Who controls the grid

State-owned KEPCO runs transmission and distribution and is the only retailer.

Markets & power exchanges

Regional grid

Not part of a larger synchronous grid or regional power pool.

What does “Single buyer” mean?

Independent power producers build plants and sell their output under long-term contracts to one designated state buyer, usually the national utility, which runs the grid and sells to consumers.
