A power amount totaling unit (641) totals the power consumption amount totaled by time period. A power cost calculation unit (642) calculates the power consumption cost (including a breakdown of the power purchase cost, power discharge cost, and power generation cost) by time period, on the basis of an electricity charge table and the power consumption amount totaled by time period. A display control unit (644) generates, on the basis of the calculated power consumption cost by time period, a power consumption cost screen in which a graph representing the power consumption cost by time period is color-coded using colors corresponding to the breakdown (power purchase cost, power discharge cost, and power generation cost). |
