PROBLEM TO BE SOLVED: To provide a power management system for stirring power saving in each building.SOLUTION: A power distribution panel 14 comprises: a trunk current sensor 16 for measuring a current value of power supplied from a system power; and a power calculation unit 20 which acquires the current value measured by the trunk current sensor 16 and calculates a power consumption amount of a building 12A from the acquired current value in association with time at which the current value is acquired. A HEMS 30 transmits the power consumption amount of the building 12A with information on time associated with the power consumption amount to an information center 60 through a communication channel 26. An operation terminal 32 can receive, from the information center 60, information on order of power consumption amounts of buildings 12A to 12D calculated on the basis of the power consumption amounts of the buildings 12A to 12D transmitted from the building 12A and buildings 12B to 12D through a communication channel 28, and display the information. |
