Abstract

There has been a problem in that when an electric power supplier carries out demand control by discount or the like, it cannot suitably estimate an amount of demand control and a cost for it. Therefore, an object of the invention is to provide a power supply plan making support method such as enables support upon making a generator operation plan and a power purchase plan by considering power demand control. A predicted cost for demand control is expressed by an equation to enable a concept of demand control to be easily reflected in equations for calculation for presenting information for an electric power supply plan, thereby enabling presentation of a suitable amount of demand control and a necessary cost.
