Abstract. Today, the electricity supplier is not able to declare the possible level of reliability of electricity supply, and the consumer simply does not have the opportunity to buy such “reliable” electricity. In such conditions, a differentiated approach to tariff formation is inevitable, which has been implemented in practice today, albeit in its infancy. Further improvement of the tariff-forming mechanism is impossible without creating a "flexible" dependence of the tariff on the indicators of the consumer's power supply reliability. Reliability indicators, in turn, are based, on the one hand, on the methods and approaches for their determination, and on the other, on statistically reliable data on the reliability of the elements that make up the equipment in the "generation-consumer" chain. Localization by automatic sectioning points at the design stage in the context of RAB tariff setting (incentive tariff setting) ensures the target nature of reducing SAIDI (index of average duration of outages in the system) and, as a result, assessing the possibility of achieving the target ENS (estimated volume of non-supplied electrical energy) significantly reduces the cost of network design and reconfiguration. In this regard, it is necessary to revise the state and topology of problem networks, including the operated partitioning hardware; to define support services in the energy company; be trained in software (for example, TELARM) as a design tool; to create the standards of the company (group of companies), taking into account the experience of colleagues from Moldova, the Security Council, the Baltic States, far abroad. As part of a scientific search, an approach was proposed, which is the basis for calculations to determine the optimal installation locations for automatic sectioning points for an average air line, as well as a parallel-serial air line with "targeted" automatic reserve input, corresponding to the optimal SAIDI value. The results obtained are presented in the framework of a joint technical meeting of leading specialists of operating enterprises, the customer and the staff of the Department of Power Supply named after A. V.M. Sinkova NULES of Ukraine.
