Abstract: The present invention relates to a power distribution control system for suppressing a total quantity of working current in a group of loads to a level equal to or lower than a set quantity of current by controlling the loads. The power distribution control system includes a central communication terminal and a plurality of customer communication terminals connected to the center communication terminal through communication lines. Each of the customer communication terminals is responsive to a presentation signal from the center communication terminal that requests time periods for, and quantities of power reduction. The central communication terminal also provides a response signal to selected customer communication terminals. The response signal indicates that a proposal for power reduction by the customer has been accepted.
