Provided are a method and a system for managing peak power based on a sub-metering. According to an embodiment of the present invention, the method for managing peak power is to measure the amount of electrical energy consumed and to manage by calculating the peak power in a shorter period than a peak power calculation cycle from a power supply company based on the measured amount. Therefore, the present invention can effectively manage the peak power in buildings and around factories with low costs for installation excluding expensive KEPCO approved products, thereby enabling reduction in electrical energy ultimately and saving in electricity costs. |
