Abstract: A demand monitoring device which monitors an amount of electric power received by a consumer includes: a prediction unit predicting, every demand period, received electric power in the object demand period on the basis of at least one of demand electric power, generated electric power, and received electric power at a time previous to the demand period, a known schedule of the consumer in the demand period, and weather information; a creation unit creating a graph showing an amount of electric power received by the consumer until a current time, a predicted value for an amount of received electric power from the current time onward, the predicted value being predicted by the prediction unit, and a target electric power amount based on contract electric power of the consumer; and a display control unit displaying the graph created by the creation unit, on a screen of a display device.

Abstract: A device according to one mode of the present disclosure relates to a device for controlling the output of a power storage device that is chargeable and dischargeable. This output control device includes: an obtainment section configured to obtain a remaining charged power amount at a present time point of the power storage device; and a control section configured to set an operation range of the remaining charged power amount of the power storage device.

Abstract: One aspect of the present invention relates to a computer program for causing a computer to operate as an energy management system for managing the operation state of electric power devices including a storage battery connected to a power grid. The program includes: a first step of acquiring static parameters used in controlling the electric power devices; and a second step of controlling the electric power devices based on the acquired static parameters. The static parameters acquired in the first step include at least five types of parameters, namely, a storage battery capacity, dischargeable power, chargeable power, discharge efficiency, and charge efficiency.
