Currently methods of efficiency analysis are being developed and applied, based on optimization tasks for various types and modes. Usually, the optimization criterion for these objectives is efficiency that can be calculated in various ways, for which there is no concurrent views. The target function based on minimization of given cost that allows comparing options with the same useful effect is used to search for the best indicators of power plants operated within the system. Marginal costs on the amount of difference in the useful effect are introduced to the target function in case of various useful effects. The criterion of selecting the best power plant from an economic point of view is the difference between the reduced costs of the considered and the basic options, but this approach does not allow using the results for long-term projections. Such approach depends on the situation and does not reflect the real costs. The value of the target function to optimize the effectiveness of the technical-economic method is not "marginal" and does not allow assessing the impact of various processes on the overall option efficiency. Therefore, the development of the efficiency criterion that considers the changing needs of the energy system is relevant for analyzing the power plant.
