Abstract
<jats:p>All consumers of electric energy (capacity) operating as part of the national energy systems have direct or indirect technological connection to the electric networks of a grid organization and have to pay for the electricity transmission. The cost of electricity transmission is high, and its pricing is different for each industrial consumer. As a result, energy consumers have to plan their energy consumption, monitor the electricity transmission pricing, and manage the costs for transportation services. The author developed a new methodology for calculating the cost of energy transmission services and capacity tariffs. The algorithm relies on the specific calculation parameters, unified regional tariffs for energy transmission, and various types of tariff voltage levels. The formulae refer to the official regulations in single-rate and double-rate terms. The article also provides a method for calculating the payment obligation for the maintenance of grid facilities. The calculations were illustrated by the example of an industrial enterprise connected to the Rosseti Siberia electric grid, Kemerovo Region. The results can be useful for energy companies, industrial enterprises, and state regulators of the electric power industry.</jats:p>
