According to one embodiment, an apparatus sends a request to adjust a power consumption to a plurality of request targets, based on power supply and demand. A minimum adjustment time of each request target is stored. The minimum adjustment time is an interval between a time when a request target receives the request and a time when the request target starts to adjust the power consumption. If an estimation value of the power supply is different from an estimation value of the power demand at a first time to start to adjust, at least one request target is selected from the request targets by using the minimum adjustment time. The at least one request target is acceptable for the request at a second time as a predetermined time prior to the first time. A first adjustment amount to the at least one request target is calculated until the second time. |
