An EMS server (14) calculates an estimated value of an integrated power consumption at an expiration of a reference time, based on a current value of power consumption of at least one load device located in a consumer's facility and a remaining time in the reference time. The EMS server (14) controls the load device in accordance with the estimated value of the integrated power consumption and a response time. The response time refers to a time required to complete a change in power consumption of the load device in response to a change in a setting of the load device.

1. A server apparatus configured to control at least one load device located in a consumer's facility in accordance with (i) an estimated value of an integrated power consumption at an expiration of a reference time that the consumer and an electric company use in calculation of power charges, the estimated value of the integrated power consumption being calculated based on a current value of power consumption of the at least one load device and a remaining time in the reference time, and (ii) a response time required to complete a change in power consumption of the at least one load device in response to a change in a setting of the at least one load device, wherein the at least one load device comprises a plurality of load devices each having a predetermined response time, wherein each of the plurality of load devices is associated with a predetermined threshold value that depends on the predetermined response time for that load device, andwherein the server apparatus is further configured to, when the estimated value of any of the plurality of load devices is greater than the corresponding predetermined threshold value, generate a control instruction to reduce power consumption of the any of the plurality of load devices. 2. The server apparatus of claim 1, wherein the server is further configured to: calculate, for each of the plurality of load devices, an amount of reduction in the estimated value at the expiration of the reference time that is caused by the change in the setting of the load device, based on the remaining time in the reference time and the response time; andgenerate at least one control instruction to make the change in the setting of at least one of the plurality of the load devices for reducing the estimated value to below a planned value. 3. The server apparatus of claim 2, wherein the at least one control instruction comprises a plurality of control instructions generated for at least some of the plurality of load devices, and the server apparatus is further configured to generate a set of the plurality of control instructions and the at least some of the plurality of load devices for reducing the estimated value to below the planned value. 4. The server apparatus of claim 1, wherein, as a difference between the estimated value and the threshold value increases, the server apparatus generates the control instruction providing a greater effect of reducing power consumption. 5. The server apparatus of claim 4, further configured to store an actual response time required to complete the change in power consumption of the any of the plurality of load devices after the change in the setting is made to the any of the plurality of load devices in response to the control instruction and to adjust the threshold value in accordance with a difference between the actual response time and the predetermined response time. 6. The server apparatus of claim 1, further configured to store an actual response time required to complete the change in power consumption of the any of the plurality of load devices after the change in the setting is made to the any of the plurality of load devices in response to the control instruction and to adjust the threshold value in accordance with a difference between the actual response time and the predetermined response time. 7. A power control apparatus configured to control at least one load device located in a consumer's facility in accordance with (i) an estimated value of an integrated power consumption at an expiration of a reference time that the consumer and an electric company use in calculation of power charges, the estimated value of the integrated power consumption being calculated based on a current value of power consumption of the at least one load device and a remaining time in the reference time, and (ii) a response time required to complete a change in power consumption of the at least one load device in response to a change in a setting of the at least one load device, wherein the at least one load device comprises a plurality of load devices each having a predetermined response time, wherein each of the plurality of load devices is associated with a predetermined threshold value that depends on the predetermined response time for that load device, andwherein the power control apparatus is further configured to, when the estimated value of any of the plurality of load devices is greater than the corresponding predetermined threshold value, generate a control instruction to reduce power consumption of the any of the plurality of load devices. 8. The power control apparatus of claim 7, further configured to (i) transmit, to a server, the current value of power consumption of the at least one load device, (ii) receives, from the server, a control instruction to the at least one load device generated in accordance with the estimated value, which is calculated based on the current value of power consumption of the at least one load device and the remaining time in the reference time, and the response time, which is required to complete the change in power consumption of the at least one load device in response to the change in the setting of the at least one load device, and (iii) control the at least one load device in accordance with the received control instruction. 9. A power control system, comprising: a power control apparatus configured to transmit a current value of power consumption of at least one load device located in a consumer's facility and configured to control the load device; anda server apparatus configured to generate a control instruction for controlling the at least one load device in accordance with (i) an estimated value of an integrated power consumption at an expiration of a reference time that the consumer and an electric company use in calculation of power charges, the estimated value of the integrated power consumption being calculated based on the current value of power consumption and a remaining time in the reference time, and (ii) a response time required to complete a change in power consumption of the at least one load device in response to a change in a setting of the at least one load device,wherein the power control apparatus receives the control instruction from the server apparatus and controls the at least one load device in accordance with the received control instruction,wherein the at least one load device comprises a plurality of load devices each having a predetermined response time, wherein each of the plurality of load devices is associated with a predetermined threshold value that depends on the predetermined response time for that load device, andwherein the server apparatus is further configured to, when the estimated value of any of the plurality of load devices is greater than the corresponding predetermined threshold value, generate a control instruction to reduce power consumption of the any of the plurality of load devices.
