In this method for optimally calculating energy operation conditions in an iron mill, the total energy operation cost of the iron mill within a predetermined time period from the current time is used as an evaluation function using the actual values and predicted values of the amount of energy service generation and consumption for each plant constituting the iron mill, and the total energy operation cost of the iron mill within the predetermined time period from the current time is used as an evaluation function. The present invention is a method for optimally calculating an energy operation condition in an iron plant, in which the value of an evaluation function is reduced at each predetermined time within a predetermined time, as a determination variable, comprises: a step for calculating a decision variable by applying an equation limit such that the decision variable relating to a power generation facility included in an energy facility becomes constant within a predetermined collection time; 本发明所涉及的炼铁厂中
