On June 30, 2020, Aneel published Homologatory Resolution 2,715, in which it ratified the result of the periodic review of the RAP of contract No. 060/2001 and on July 14, 2020 it issued Homologatory Resolution 2,725, which establishes the RAP for making available the facilities under the responsibility of the Company. In the process of the first tariff review of contract No. 060/2001, referring to the tariff cycles of 2018/2023 and which takes place every five years, operating costs, the cost of capital (WACC) and the remuneration base were reassessed, which resulted in a 10.16% RAP repositioning rate in relation to the previous cycle.

Additionally, in relation to RBSE assets, Ratifying Resolution No. 2,715 set the tariff repositioning and included the “remuneration” in the portion of RAP, which had previously been provisionally excluded due to a judicial decision now overturned. Such amounts will be received from the fourth tariff cycle started in July 2020 until June 2025, including the addition of amounts not timely received due to the provisional effects of the injunction, which will be added in the next three RAP cycles beginning in July 2020 until June 2023. The impact of the tariff review on RBSE assets totaled R$ 122,027, recorded in 2020 operating revenue.

11.3.1

Gain (loss) due to efficiency or inefficiency in the implementation and operation of transmission infrastructure

In the construction and operation of the transmission infrastructure, possible positive or negative impacts are expected due to delays and additional costs due to environmental issues, variation in costs, mainly with cables and structures when indexed to foreign currency, additional easement costs and land negotiations, potential earthworks for unforeseen events, early maturity of commercial transactions and RAP revision/readjustment according to the regulatory standards and contractual provisions. Changes in the original project that affect its profitability are recognized directly in the statement of income when incurred, except for the part of RAP related to the operation and maintenance performance of the assets that is recognized as the services are performed.
