Trading amounts are calculated every 2 days after trading based on the bidding data, metered data, and dispatch data.
The settlement process consists of two steps: preliminary settlement and final settlement. The result of each settlement is posted on the Internet.

• Power generation companies and electricity supplier (KEPCO) are notified of the preliminary settlement 9 days after the trading.
• KPX examines the preliminary settlement in case a member company raises an objection. The notice regarding the final settlement is issued within 22 days.
• After receiving the trading payment from KEPCO, KPX transfers funds to power generation companies on the same day.
