Abstract
This server (10) comprises a processor (11) that executes a computation process for determining in which energy storage facility among a plurality of energy storage facilities (30) to store electric power generated from a naturally fluctuating electric power supply (20). When the electric power generated from the naturally fluctuating electric power supply (20) exceeds the electric power consumption of a building and surplus electric power is generated, the processor (11) extracts, from among the plurality of energy storage facilities (30), one or more energy storage facilities in which a period during which the surplus electric power exceeds a prescribed amount is longer than a period during which continuous energy storage is required in accordance with the specifications of the facility. The processor (11) calculates, for each of the one or more energy storage facilities, an amount by which an electricity bill will be reduced in the event that the surplus electric power is stored in said energy storage facility, and determines the energy storage facility in which to store the surplus electric power on the basis of the amount of reduction.
