<p>A controller (13) includes a request acquisition unit (131) which acquires a request signal requesting permission of an operation from a device, a calculation unit (132) which calculates margin electric power on the basis of a result of the measurement by the measurement unit and upper limit electric power, and a suppression unit (133) which instructs suppression of the electric power consumption to the device. When the margin electric power is smaller than the required electric power, the controller (13) suppresses the electric power consumption in devices in order of lower priority stored in the priority storage unit (16), in the suppression unit (133), such that the increased amount of electric power in use in the management area may remain within the margin electric power. After that, controller (13) notifies the device as a transmission source of the request signal of permission-or-denial information indicating permission-or-denial for the operation, from the calculation unit (132). Accordingly, if there is a request for required electric power from a device, the electric power consumption in other devices is suppressed to shorten the time taken for securing the margin electric power.</p> |
