with preliminary R$8.3 billion RAB

Companhia Paranaense de Energia - COPEL (“Company”) company that generates, transmits, distributes and trades energy, with shares listed on B3 (CPLE3, CPLE5, CPLE6), NYSE (ELPVY, ELP) and LATIBEX (XCOP), communicates to its shareholders and the market in general that, National Electric Energy Agency (“Aneel”), published on this date Public Consultation Notice 11/2021 which aims to obtain subsidies for the process of the 5th Periodic Tariff Review Cycle of Copel Distribuição S.A., being that the net amount of the regulatory remuneration base (“RAB”) was preliminarily established at R$8.3 billion.

The consultation notice also includes preliminary information on other items of the process, such as:

• Portion A, which includes costs with charges, transportation and energy, of R$9,031,844,871;

• Portion B, comprising operating costs, annuities, remuneration, depreciation, sunk revenue and others, of R$2,740,900,806;

• Factor X, defined based on the potential gains in productivity, compatible with the growth of the market and the number of consumer units, the quality of service, and the transition from efficient operating costs, of -0.49%.

The benchmark for regulatory losses was proposed at 5.47% on the injected energy for technical losses and 4.87% on the low voltage market for non-technical losses for the entire cycle, with no reduction target.

Also according to the Agency, a preliminary rate review rate of 9.67% was established (average effect to be perceived by the consumer).

The amounts are preliminary and are subject to the final decision of the regulatory body after the conclusion of the public consultation process. The tariff revision numbers will be known at the time of their final approval by Aneel, scheduled to take place in June 2021, and will be applied as of June 24, 2021.
