This article discusses the issues of determining the predicted values of rationing the power consumption of industrial enterprises. For a certain pattern of change in power consumption and specific power consumption, hourly productivity was studied, which determines the performance of units. On the basis of the predicted values of the output volume, the norms of energy consumption were developed, which are reflected taking into account its specifics, the energy intensity of the products. In developing the norm, the calculation method was adopted based on the analysis of static data for a number of previous years on actual energy consumption, the volume of output of factors affecting their change.
