18.4Impairment of generation segment assets

Cash-generating units of the generation segment were tested for impairment based on previous evidence of impairment, assumptions representing the best estimates of the Company’s management, the methodology provided for in IAS 36 and measurement of value in use.

The calculation of the value in use was based on discounted operating cash flows over the time of concessions, maintaining the Company’s current commercial conditions. The rate used to discount the cash flows was set and updated considering the WACC (Weighted Average Cost of Capital) methodology and CAPM (Capital Asset Pricing Model) methodology for the generation business, considering usual market parameters.

Internal references such as the budget approved by the Company, historical or past data, updating of the timeframe of work and amount of investments for projects in course support the design of key assumptions by Company Management. In the same framework, external references such as level of consumption of electric power and the availability of water resources support the key information about estimated cash flows. In particular, 2020 and 2021 proved to be atypical years in terms of growth of the economic activity in the country and in the world, due to the Covid-19 pandemic and, consequently, due to measures to contain it, which directly had an impact on trade, industry and services.

A number of assumptions used by Company Management when determining future cash flows can be affected by uncertain events, which, in turn, may give rise to variation in results. Changes in the political and economic model, for example, may lead to upward trend when projecting country risk-rating, increasing the discount rates used in tests.

The tests considered the following key assumptions:

·Growth compatible with historical data and perspective for the Brazilian economy growth;
·Updating specific after-tax discount rates for the segment tested, obtained through the methodology usually applied by the market, taking into consideration the weighted average cost of capital;
·Projected revenue in accordance with the agreements in force and future market expectations, without any expectation for renewal of concession/authorization;
·Expenses broken into cash generating units, projected in view of the budget approved by the Company;
·Updating of regulatory charges.

The Company considered all its generation projects as independent cash generating units.

18.4.1UHE Colíder

In December 2021, the calculation of value in use took into account the Company’s assumptions and budgets and the discount rate after taxes of 5.77% p.a. (in 2020, 5.70% p.a.), which derives from the WACC methodology for the electricity generation segment. The revision in the expected sale of uncontracted energy offset the increase in operating costs and regulatory charges, reflecting the partial reversal of the impairment balance recognized in prior periods.

18.4.2Wind farms

In December 2021, the calculation of value in use of wind power assets took into account the Company’s assumptions and budgets and the discount rate after taxes of 7.65% p.a. (in 2020, 7.08% p.a.) which derives from the WACC methodology for the electric power generation segment, adjusted for the specific taxation condition of the projects. In particular, for the test of the Vilas Wind Complex, acquired at the end of 2021, the after-tax discount rate of 5.46% p.a. was adopted according to the financing contracted before the acquisition. Based on the calculations of the wind farms, it was verified that these assets are recoverable and that, therefore, there is no need to recognize impairment.

18.4.3UEG Araucária

In December2021, the calculation of the value in use considered the Company’s assumptions and budgets, change of dispatch assumptions, updated of variable cost per unit (CVU) and discount rate after taxes by 7.69% p.a. (in 2020, 7.87% p.a.), which derive from the WACC methodology for the electricity generation segment, plus additional risk associated with revenue variation. By reviewing the assumptions, the impairment recognized in previous periods were fully reversed, mainly in view of the increase in plant’s demand as a result of the unfavorable hydrological conditions associated with the ONS operating policy to guarantee energy supply, including the restoration of the hydroelectric plant’s reservoirs, which makes the UEG Araucária dispatch assumptions take place in a longer period than predicted in previous projections.

18.4.4Figueira Thermoelectric Plant

In December 2021, the calculation of the value in use considered the Company’s assumptions and budgets, the discount rate after taxes of 5.77% p.a. (in 2020, 5.70% p.a.), which derives from the WACC methodology for the electric power generation segment, the postponement of the start of the operation to April 2022 (in 2020 it was considered July 2021), changes in operating costs and remaining investment, review of the coal contract and review of the CCEE subsidy for the plant. By reviewing the set of assumptions, additional impairment was recognized in the period.

18.4.5Other plants in Paraná:

In December 2021, the calculation of the value in use of generation assets in the State of Paraná considered the Company’s assumptions and budgets, the discount rate after taxes at 5.77% p.a. (in 2020, 5.70% p.a.), which derives from the WACC methodology for the electric power generation segment, and the review of regulatory charges and operating costs that were offset by the review of the expected sale of uncontracted energy. By reviewing the set of assumptions, part of the impairment recognized in previous periods was reversed.

18.4.6Cash-generating units that have no impairment

Plants that have no impairment have recoverable amount higher than the carrying amount of property, plant and equipment on December 31, 2021. The following table shows the percentage by which the recoverable amount (“RA”) exceeds the carrying amount (“CA”) of generation assets and also demonstrates the sensitivity analysis, increasing the discount rate by 5% and 10% to assess the risk of impairment of each plant.

18.5New plants under construction
18.5.1SHPP Bela Vista

With estimated investment of R$224,673, this small hydroelectric power plant (SHPP), with installed capacity of 29.81 MW and physical guarantee of 18.4 MW average, was built on the Chopim River, in the municipalities of São João and Verê, located in the southwest region of the State of Paraná.

The participation in the A-6 auction held on August 31, 2018 led to sale of 14.7 MW average in regulated contracts at the original price of R$195.70/MWh. The energy sale contracts provide for beginning of energy supply on January 1, 2024, with a 30-year term and annual adjustment by reference to IPCA variation.

The works started in August 2019, with the entry into commercial operation of the first and second and third generation units on June 12, 2021, July 10, 2021 and August 15, 2021 respectively. The entry into commercial operation of the fourth unit is scheduled for the first half of 2022.

18.5.2Jandaíra Wind Complex

With estimated investment of R$411,610 this wind farm, with installed capacity of 90.1 MW and physical guarantee of 47.6 MW average, is being built in the municipalities of Pedra Preta and Jandaíra, in the Rio Grande do Norte State.

The participation in the new power generation auction A-6, held on October 18, 2019, led to sale of 14.4 MW average in regulated contracts at the original price of R$98.00/MWh. The energy sale contracts provided for beginning of energy supply on January 1, 2025, with a 20-year term and annual adjustment by reference to IPCA variation.

In all, 26 wind turbines will be installed, divided into four wind farms, and a substation and a 16 km transmission line will also be built next to the farms to drain the electricity to be generated for the National Interconnected System - SIN.

With all the necessary licenses in place, civil works began in the first week of January 2021, and the wind farm is expected to start operating between May and July 2022, on a phased basis, by wind turbine.

In 2021, the Company’s Management reassessed the estimated useful lives of assets in the generation segment, mainly for the effects of the hydrological risk renegotiation - GSF (Note 1 - b). The changes were treated prospectively as of October 2021, including the depreciation quota for this year, together with the amortization of the intangible asset recognized on September 30, 2021, in the amount of R$50,880. Additionally, they will include, on average, the amounts of R$203,517 in 2022, R$205,180 in 2023, R$210,098 in 2024, and R$82,725 from 2025 to 2033.

18.6.1Assets with depreciation rates limited to the concession term

The assets of the original project of the Mauá, Colíder, Baixo Iguaçu, Cavernoso II and SHPP Bela Vista plants, of Copel GeT, and of the Santa Clara and Fundão plants, of Elejor, are considered by the Granting Authority, without full guarantee of indemnification for their residual value at the end of the concession term. This interpretation is based on the Concessions Law No. 8,987/1995 and Decree No. 2,003/1996, which regulate the generation of electricity by independent generators. Accordingly, from the entry into operation of these assets, including land, depreciation is recognized at the highest rate among that determined by the useful lives of the assets or the rate calculated based on the concession period.

As provided for in the concession contracts, subsequent investments not foreseen in the original project, as long as approved by the Granting Authority and not yet amortized, will be indemnified at the end of the concession period and depreciated at the rates established by the useful lives of the assets, as from the date of their entry in operation.
