The article proposes the models of rational resource allocation for the implementation of measures to prevent industrial accidents in energy supply systems. They allow maximizing the integral effect of preventing these accidents, as well as eliminating their consequences in the event of restrictions on the resources allocated. As a unified measure of the volume of resources, the cost of implementing these measures has been adopted. The integral effect of financing events is estimated by an indicator formed by various options for combining private indicators of the effect of their financing. Analytical relationships have been obtained for a number of options for representing the integral effect of financing measures to prevent industrial accidents in power supply systems. They cover a fairly wide range of interesting practical problems that allow assessing various types of synergistic effect due to the distribution of available resources for financing the activities under consideration. This makes the proposed models useful for energy management at the micro and macro levels. Their practical application in the interests of energy management is associated with the choice of one or several models reflecting the specifics of measures to prevent technological accidents in power supply systems and the specification of the constant parameters of these models taking into account the specifics of these measures.
