Abstract

The priority of a demand regulating control for a device is changed in accordance with a simple operation by a consumer. A demand regulating system has an operation unit that selects from among a plurality of consumption devices, on the basis of priority information and a regulating quantity, a plurality of control-target devices, which are targeted for demand regulating control reducing consumption of the resource. A control unit executes the demand regulating control on the basis of a control instruction; and an input unit receives a first operation by the consumer, and transmits first request information requesting a change in the priorities of the plurality of control-target devices, to the operation unit in accordance with the first operation. The operation unit, upon receiving the first request information, specifies the plurality of control-target devices, and changes the priorities of the plurality of control-target devices in the priority information.
