Abstract
Operations of nuclear power plants have been suspended in various locations due to the Great East Japan Earthquake. However, it is not necessarily essential to undertake strict emergency energy saving measures at all times. In order to solve the aforementioned problems, the present invention proposes an energy saving system comprising an electrical power consumption quantity information acquisition unit for acquiring information on the quantity of electrical power consumed for a plurality of electric devices, a target demand value storage unit for storing a target demand value for electrical power consumption, a supply surplus indicator acquisition unit for acquiring indicators of surplus electric power supplied by an electric power company having control over electrical power within a certain region, and a control unit for controlling the plurality of electric devices based on the acquired supply surplus indicators, the acquired electrical power consumption quantity information, and the stored target demand value.
