A prediction calculator uses a prediction model to determine a predicted value of an amount of power to be generated by a power generation apparatus and a predicted value of an amount of power to be consumed by an appliance. The predicted values are associated with accuracy information. An operation planner makes an operation plan using the predicted values determined by the prediction calculator, a user schedule included in user setting information, and an electricity rate table or weather forecast information. When the accuracy of the predicted value is lower than a predetermined reference, the operation planner makes the operation plan only using other information without using the predicted value.

A device information acquirer acquires device information of each electrical device of a plurality of electrical devices from a control apparatus. A device information display associates and displays on a screen an identifier, an expected installation location, and a device state for each electrical device based on the device information of each electrical device acquired by the device information acquirer. The device information acquirer acquires from the control apparatus the device state information of an electrical device of interest newly collected by the control apparatus after the electrical device installed at the expected installation location of the electrical device of interest is operated by the user. The device information display explicitly shows on the screen whether the device state of the electrical device has changed due to the operation by the user based on the device state information of the electrical device of interest acquired by the device information acquirer.

A controller stores an apparatus-room association table in which an apparatus installed in a home is associated with a room in the home, and stores a room-user association table in which the room in the home is associated with the user. The controller determines whether the user is inside the home, and updates a user status. When the user status changes, the controller determines the apparatus corresponding to the user whose user status has changed, and controls the determined apparatus to execute a predetermined process based on the apparatus-room association table and the room-user association table.

In an appliance control system, a receiver receives, from a terminal device used by a first user, an instruction for remotely controlling an appliance installed in a home. A determiner determines whether a second user is present in a location in which an appliance-to-be-instructed is installed. When it is determined that the second user is not present in a location in which the appliance-to-be-instructed is installed, an appliance controller controls the appliance on the basis of the instruction. On the other hand, when it is determined that the second user is present in the location in which the appliance-to-be-instructed is installed, the appliance controller does not control the appliance.

Element data included in a management screen for management of a home electric appliance is stored in a server and a home electric appliance. A screen definition data storage stores screen definition data that defines content of the management screen and that includes an update specification that is stipulated for each of the element data to be acquired. A cache data storage stores the element data acquired beforehand from the server and the home electric appliance. The screen generator acquires, on the basis of the update specification included in the screen definition data, each corresponding element data from the cache data storage, or from the server and the home electric appliance, and generates the management screen. The controller transmits the generated management screen to the terminal device and causes display of the management screen.

An energy management controller acquires, for each of power lines in a demand area, from devices, measurement data relating to a power value measured by each device. The energy management controller selects, when power values are measured from a single power line, one power value as a power value measured from the power line, based on a priority assigned beforehand to each device. Then, the energy management controller manages power consumed in the demand area using the power value measured from each power line. Furthermore, the energy management controller causes an operation terminal to display, in a predetermined mode, information indicating the power value measured from each power line.

A prediction value calculator calculates a prediction value of an electricity fee based on the amount of electric power supplied from a commercial electric power source to electric equipment within an electricity fee calculation period. A selector selects, as a first-stage control, either one control of an electric power saving control for the electric equipment and a charge-discharge control in which the electric power supplied from the commercial electric power source is stored in a storage battery in a first time slot and the electric power stored in the storage battery is supplied to the electric equipment in a second time slot in which the unit cost of the electric power supplied from the commercial electric power source is greater than that in the first time slot. A controller executes the first-stage control selected by the selector when the prediction value calculated by the prediction value calculator is greater than a targeted value of the electricity fee.
