Payment for grid connection is calculated in cases when newly commissioned, previously connected renovated devices are connected, with increased maximum capacity, as well as when the power supply reliability category, connection points, type of production activities of already connected devices are changed without involving the revision of maximum capacity, but involving the change of the external power supply scheme of such devices.

Payment for grid connection when changing the category of reliability is calculated for the volume of maximum capacity of the applicant's consumer terminals with the changed category of reliability.

Payment for grid connection in cases of changes in the external power supply scheme that do not entail the revision of the maximum capacity as a result of changes in connection points, types of production activity, is calculated for the maximum capacity volume specified in the grid connection application.

For the regulatory period:

• standardised tariff rates (uniform for all territorial grid organisations in the territory of a constituent entity of the Russian Federation - in accordance with Federal Law No. 450 dated December 30, 2015);
