  • Publication number: 20190130423
    Abstract: To solve such a problem, demand categories are prepared. ‘Demand categories’ are units of classification for demand. Where the demand included in the ‘demand categories’ is concerned, any attribute such as the contract type, industry type, demand location, and demand generation period constitute the same demand. For example, a management apparatus comprises a sales income calculation unit which calculates sales income derived from supplying demand by using a time interval-differentiated fee unit price for each demand category and a power usage value, an earnings prediction spread calculation unit which compares earnings for each of a plurality of future volume estimation time series relating to power usage volumes of predetermined periods of the demand categories, and a fee unit price search unit which searches for a fee unit price satisfying a limiting condition based on a comparison result.
