This electric power system 1 is provided with: factories 60 and 70 having electricity demanding facilities; an independent electricity generating device 40 which supplies generated electric power to the factories 60 and 70; and power transmission lines 30 connecting the factories 60 and 70 to the independent electricity generating device 40. The electric power system 1 sells surplus electric power to an external power supply and demand device 90 by way of the power transmission lines 30. The electric power system 1 is also provided with: an electricity storage device 50 which is connected to the power transmission lines 30, stores electric power generated by the independent electricity generating device 40, and supplies stored electric power to the factories 60 and 70; a database 20 in which manufacturing plan information for the factories 60 and 70 is accumulated; and an electric power control device 10 which predicts the future electricity demand of the factories 60 and 70 on the basis of the manufacturing plan information, instructs the independent electricity generating device 40 to vary the amount of generated power, on the basis of variations in the predicted electricity demand, and instructs the electricity storage device 50 to store or discharge electric power. |
