PROBLEM TO BE SOLVED: To provide a power supply system which adaptively controls charging of a power storage part, and accurately suppresses electric energy of system power to be consumed per unit time from increasing.SOLUTION: A power supply system 1 comprises: a power storage part 2 which is charged by consuming the system power supplied from an electric power company, and supplies the charged power by electric discharge; a power storage part control part 3 which controls charging and electric discharge of the power storage part 2; and a load part 4 which is operated by consuming the system power and the power supplied from the power storage part 2. The power storage part control part 3 controls the system power to be consumed due to the charging of the power storage part 2, so that the electric energy of the system power to be consumed from a start time of the unit time until a certain time during the unit time is equal to or less than a short-term target value which is obtained by converting a target value set with respect to the unit time to a value of the certain time.
