摘要

PROBLEM TO BE SOLVED: To provide a power supply system, power use price calculation device, power supply method, and power use price calculation method for making power generated on the basis of natural energy be used more.SOLUTION: A power supply system 1 supplies power to a plurality of supply destinations. A power quality designation unit designates, depending on a facility of a supply destination to which power is to be supplied, a quality level of power to be supplied to the supply destination from quality levels capable of being supplied to the supply destination. A criterion for calculating a price so that prices are different in the case of individually using the same amount of power having different quality is set depending on a quality level of power. The price calculation unit calculates a price in the case of using power having the designated quality level on the basis of the criterion.SELECTED DRAWING: Figure 1
