Electricity Market Trading Process

홈으로 > Market Operation > Electricity Market Trading Process

KPX operates the power market where sellers, power generating companies (74 members as of 2006), and the single buyer(KEPCO) participate. The power market is dubbed the pool, suggesting that the electricity generated from all power plants converges in one place for trading. KPX conducts fair and transparent market operations from bidding, settlement, metering, market surveillance, and information dissemination to dispute resolution in accordance with the Pool Rule.
