The invention relates to an orderly power utilization management method. The orderly power utilization management method comprises the steps that a load characteristic curve of public transformer subscribers, a load characteristic curve of special transformer subscribers and a load characteristic curve of individual line subscribers are obtained by using a data mining and analysis method on the basis of massive power load data; the coefficient of correlation between each load characteristic curve and a load curve of the corresponding subscriber is calculated, and the subscriber is placed into the class of the load characteristic curve, wherein the coefficient of correlation between the load characteristic curve and the load curve of the subscriber is highest; load shifting potential of the subscribers of all the types is calculated, the subscribers with the higher load shifting potential are selected, corresponding economic measures and technological means for improving the load characteristic curves are developed through research according to different types of the subscribers with the higher load shifting potential, specific measures and a corresponding subscriber list are generated, and load characteristic analysis of a power grid is accomplished.
