3.2.9 Tariff Policy

Electricity transmission tariffs

In 2021, the regulators applied the return on invested capital method (RABregulatory asset base) to Sverdlovenergo and method of long-term indexation of the gross revenue requirement (INDEX) to Permenergo and Chelyabenergo.

 

Permenergo INDEX 5 years (2018-2022)
Sverdlovenergo RABregulatory asset base 13 years (2011-2023)
Chelyabenergo INDEX 5 years (2018-2022)

Uniform (“pie”) tariffs comprise expenses of all grid companies operating in the region to be annually prescribed for the next year during the long-term regulation period. Pursuant to existing tariff regulation laws, a gross revenue requirement is subject to annual fine-tuning, adjusted for changed real and target calculations, executed investment program and achieved reliability and quality of service indicators. Uniform (“pie”) electricity transmission tariffs to be enforced in 2021 were approved by the tariff decisions of the relevant regional regulators[21-23]:

Uniform (“pie”) electricity transmission tariffs for 2021 were set by the regulators of the Sverdlovsk and Chelyabinsk regions in line with the FASFederal Antimonopoly Service-approved minimum and maximum levels of tariffs. Uniform (“pie”) electricity transmission tariffs for 2021 in the Perm region were set by the regulator above maximum levels of tariffs[24].

Technological connection fee

Pursuant to the Guidelines on calculating a connection fee[25] the regulators of the Perm, Sverdlovsk and Chelyabinsk regions have set the 2021 standardized tariff rates (Section II of the Guidelines), maximum capacity unit rates (Section III of the Guidelines) and connection fee formulas.

The regulators have set a RUBruble 550.0 (plus VATvalue-added tax) connection fee for all Company’s branches to be applied to applicants, requesting connection of grid equipment with the capacity of 0-15 kW inclusive (incl. previously connected capacity at the point), when facilities, referred to the 3rd reliability category (from one source of electricity supply), are connected, provided that the distance between the boundaries of an applicant’s land plot and Company’s facilities at 20 kVkilovolt inclusive does not exceed 300 m in urban areas (cities and small towns) and 500 m in rural areas

The 2020 connection fees were approved by the regional regulators[26-28]:

Company’s average connection fee per maximum capacity unit, as compared to 2020, increased in 2021 mainly due to rate indexation, changes of structure of revenues from connection resulting from changes in the number of connection contracts and volumes of connected capacity per one connection. Reduction of average standardized rate for execution of organizational and technical measures is influenced by reduced standardized tariff rates S1 for the Perm and Sverdlovsk regions.

During 2021, the Company decided to connect 3 facilities to the network under individual projects:
