Abstract: A time point range setting unit (110) sets an operation startable time point when an operation is startable, and an operation end target time point which is a latest time point among time points when the operation is to be ended, with respect to each of plural power-consuming bodies (20). A necessary operation time setting unit (120) sets a necessary operation time with respect to each of the plural power-consuming bodies (20). A shape information obtaining unit (130) obtains shape information from a schedule management apparatus (40). The shape information represents an assumed shape of a transition line indicating transition in the amount of power supplied in a target period. A demand transition setting unit (140) determines power demand transition information indicating transition in electrical energy demand in the target period so that the necessary operation time is obtained and the transition in the electrical energy demand generated by the plural power-consuming bodies (20) being operated follows the assumed shape.
