On the basis of the analysis of references and suggested approaches selected integral indicator of the efficiency of the electricity system electrification of the railways. It represents a return on refining the electricity system, which is proposed to determine the ratio of revenue from the purity of the processing power to its processing costs. The technique of definition of these components of the costs should be taken into account the cost of energy losses in power supply devices, the cost of electricity to the property, the wage fund with accrual taxes depreciation charges, other operating costs. Performance indicators are normalized. In this case, the statutory rate, you can use the tariff to overwork one kilowatt-hour of energy. Moreover, its value should encourage the use of science and technology, increased productivity, efficient use of raw materials and energy resources, as well as improving the quality of electricity and reliability of energy efficiency.
