Demand monitoring device, demand monitoring system, demand monitoring method, and demand monitoring program

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.
