Claim:
1. A power equalization device, comprising: a power demand prediction function of predicting power consumption expected when a plurality of materials are processed at different locations of a manufacturing plant or manufacturing line of a metallic material; a power equalization control function of causing a power storage device to make the manufacturing plant or the manufacturing line perform discharging in the case where power consumption predicted by the power demand prediction function exceeds a prescribed value, so that power supplied to the manufacturing plant or the manufacturing line from an external power system becomes not more than the prescribed value; an operation schedule prediction function of predicting location and time for manufacturing each of rolled materials in the manufacturing plant or the manufacturing line; and an individual-product power consumption prediction function of predicting power consumption expected when each of the rolled materials is manufactured at the location, wherein on the basis of the location of each of the rolled materials at a point of time, the power demand prediction function calculates power consumption expected when each of the rolled materials is manufactured at the point of time, and regards an integrated value of a calculated value of power consumption expected when each of the rolled materials is manufactured as a predicted value of power consumption of the manufacturing plant or the manufacturing line at the point of time, and wherein the operation schedule prediction function makes a comparison between a predicted value and an actual value of location and time expected or obtained when a rolled material is manufactured in the manufacturing plant or the manufacturing line and improves a prediction accuracy of location and time expected when each of the rolled materials is manufactured.
