Method for predicting power load and apparatus using the method

Disclosed are a method for predicting power load and an apparatus using such a method. The method for predicting power load may comprise the steps of: receiving weather forecast information; determining unit time power data group to be used for calculating predicted power load on the basis of the weather forecast information; and calculating the predicted power load on the basis of the weather forecast and unit time power data contained in the determined unit time power data group. Accordingly, the predicted power load can be accurately calculated on the basis of the time and temperature data.
