Power is supplied to electrical devices while priorities between the electrical devices are being changed according to the states of use by a user instead of predetermined fixed priorities between the electrical devices, supply of power from a commercial power source can be controlled in real time at a request for power required by the user, and supply of power meeting QoL required in user's daily life is controlled. A power manager determines power to be assigned to each electrical device by inquiring a home appliance agent of whether or not the electrical device is capable of adjusting an operating function mode set as a target of a service operation of the electrical device, and of power for the electrical device. If the electrical device is capable of adjusting the operating function mode, the power manager obtains as a power assignment message the operating function mode set as a target for the electrical device and/or a power mode with power necessary for reaching the operating function mode as a target and with necessary time. If the electrical device is not capable of adjusting the operating function mode, the power manager obtains a power mode as a power assignment message without considering the operating function mode. The power manager includes a memory for transmitting the obtained power assignment message to the home appliance agent.
