PROBLEM TO BE SOLVED: To provide a power demand control system capable of prompting power saving or, conversely, prompting power consuming depending on a situation, by changing a user's contract current value by controlling the value externally.SOLUTION: A power demand control system includes: a trunk breaker 7 which is assembled to a power distribution board 6 and to which a breaking current value for a cable way is set according to a contract with a power supply company; a server 11 disposed on a general-purpose communication network S in order to perform change control on the trunk breaker 7's breaking current value. The trunk breaker 7 comprises: a breaker communication IF for receiving a control signal from the server 11; and a trunk breaker CPU 18 for receiving the control signal to change the breaking current value. The server 11 grasps power consumed by the whole user H and supply capability of a power supply company 1; and when it is determined that a power supply/demand balance is tight, performs control of decreasing the trunk breaker 7's breaking current value.SELECTED DRAWING: Figure 1 |
