PROBLEM TO BE SOLVED: To contribute to maintaining a satisfactory electric power demand-supply balance by reducing fluctuations in power consumption from day to day.SOLUTION: An energy managing apparatus 10 for monitoring the wattage consumed during a reference time length used in unit power price determined with an electric power supplier comprises an acquiring unit 111 for determining characteristics information on a storage battery 15 and a control unit 112 for controlling the storage battery 15. The control unit 112 figures out from the characteristics information on the storage battery 15 the time length needed by the storage battery 15 to discharge the minimum wattage unit determined by the electric power supplier in power price determination and, in monitoring the reference time length, determines whether or not to cause the storage battery 15 to discharge power in the reference time length not later than the lapse of the discharge time length counted back from the end of the reference time length.
