Korea Power Exchange_System Marginal Price and Demand Forecast (for day-ahead power generation planning)

This service provides hourly system marginal price information and demand forecasts for the mainland and Jeju Island. Each hour is indicated as the end point of its respective period (i.e., a trading hour of 6:00 indicates a period starting immediately after 5:00 AM and ending at 6:00 AM). Data is updated once a day, around 11:00 PM. The existing system marginal price query API will be removed in the future.
