Operations	1. Operations Companhia Paranaense de Energia (Copel, Company), with its head office located at Rua José Izidoro Biazetto, 158, bloco A, Curitiba - State of Paraná, is a publicly-held mixed capital company controlled by the State of Paraná and its shares are traded at Corporate Governance Level 1 of the Special Listing Segments of B3 S.A. - Brasil, Bolsa Balcão Stock Exchange and also on the New York Stock Exchange (NYSE) and on the Madrid Stock Exchange, in the Latin American segment (Latibex). The core activities of Copel and its subsidiaries, which are regulated by the Brazilian Electricity Regulatory Agency (ANEEL), linked to the Brazilian Ministry of Mines and Energy (MME), are to carry out research, study, planning, and asset building activities related to the generation, transformation, distribution and trading of energy in any of its forms, primarily electricity. Furthermore, Copel has participations in consortiums and in private sector and mixed-capital companies for the purpose of engaging in activities, primarily in the fields of energy and natural gas. On August 03, 2021 the divestment is telecommunications participation was concluded (Note 41). a) Coronavirus pandemic (Covid-19) and its impacts Coronavirus is a family of viruses discovered in 2019 after cases registered in China and causes the disease called Covid-19, which has clinical symptoms ranging from asymptomatic infections to severe respiratory conditions. On February 26, 2020 the first case of infection was identified in Brazil, in the city of São Paulo and on March 11, 2020, World Health Organization - WHO attributed the status of pandemic to coronavirus, in view of the spread of contamination throughout the world. In Brazil, federal state and municipal governments have implemented several measures of action with the public health emergency. In the state of Paraná, measures included social isolation and restrictions on the operation of non-essential activities as a way to slow the spread of the disease, as well as expanding vaccination for the general population. After an aggravation cycle of the pandemic that lasted until mid-June 2021, there was a reduction in social isolation and increase in economic activity from this period, mainly due to the advance of vaccination, which reflected in the decrease in severe cases of the disease, even with the increase in infections by the Ômicron variant in late 2021 and early 2022. As of March 2020, Copel’s Management issued rules that aim to ensure compliance with the measures to contain the spread of the disease in the Company and minimize its impacts and potential impacts on the administrative, operations and economic-financial areas. Accordingly, Copel established a Contingency Commission, whose objective is to monitor and mitigate the impacts and consequences in the main activities of the Company. The 4 pillars defined are: (i) safety of personnel, (ii) continuity of essential activities, (iii) monitoring of the guidelines and requirements of regulatory bodies, and (iv) preservation of adequate financial conditions to withstand the crisis Among the main initiatives implemented by the Company, there are actions to prevent and mitigate the effects of contagion in the workplace, such as: adoption of home office in areas where it is possible to adopt this format, travel restrictions, meetings by video conference, daily monitoring of the health and well-being of employees and contingency protocols in order to fully maintain the operations of the electric power and piped gas infrastructure, preserving the health of its professionals, their safe access to locations, an environment that preserves distance between individuals, hygiene and access to personal protective equipment. Likewise, Copel has adopted several activities in favor of its customers, maintaining the reliability and availability of its plants, the transmission and distribution systems of electric power and gas, so that they can remain connected and take advantage of Company services in this moment of pandemic. Effects from coronavirus (Covid-19) on the financial statements Copel has been continuously monitoring energy load projections and from the second quarter of 2021 there was a resumption of most sectors of the economy, the load in the National Interconnected System - SIN in 2021 increased by 4.1% compared to 2020, the result of which is mainly attributed to the progressive reduction of restrictive measures to combat Covid-19. With regard to the implementation schedule of energy distribution, generation and transmission projects, or even on the availability of existing assets resulting from local actions that prevent access to facilities or problems with suppliers in the sector, also affected by the downturn, Management, diligently, continues to monitor the deadlines for construction works in progress and has maintained continuous communication with the concession regulator regarding any delays that may occur until the normalization of commercial activities in the overall market. The Company’s construction in progress to date have not had any significant delays. With the objective of mitigating the impacts and consequences on its main activities, Copel has been continuously monitoring its contracts, liquidity in the energy market and the short-term energy price, as well as communicating with the Regulatory Body of the Brazilian energy sector for the implementation of guidelines ensuring maintenance of economic and financial sustainability of the entire chain of energy generation, transmission, sale and distribution. In this scenario, for the purposes of preparing and disclosing these financial statements, the Company’s management evaluated its estimates in order to identify the possible impacts of Covid-19 on the Company’s business, as follows: a.1) Expected credit losses A potentially relevant risk in the emergence of Covid-19 is related to customer default. In this scenario, the Company maintains regular contact with its main customers, adding flexibility to the collection policy during the pandemic period and increasing the level of digitalization in the relationship with Copel. In relation to the captive energy distribution market, Copel, after the end of the restrictions imposed by Aneel, resumed the collection actions with defaulting consumers and created special conditions for debt payment in installments, providing conditions to consumers in remaining compliant with the Company. On March 26, 2021, Aneel Resolution No. 928 was issued, which prevents the suspension of energy supply to low-income consumers and some other consumer groups, with no relevant impact for Copel, given that these consumers are already covered by the State Law No. 20.187/2020 which also deals with the prohibition of power supply cuts. In the area of ​​energy contracts entered into on the free market, to reduce the impact on collection and avoid future legal disputes, Copel renegotiated with customers with difficulties in complying with contracts, proposing installment payments and postponing the maturity of invoices. Both the Company’s accounts receivable position as well as the estimates of expected credit losses recorded on December 31, 2021 reflect, in a timely manner, the best analysis by Management at this time on the quality and recoverability of this financial asset. Although the loss indicator has not significantly deteriorated, the Company may face pressure on this indicator if the pandemic lasts longer and if implemented stricter restrictions on social distancing. a.2) Impairment of non-financial assets - impairment On December 31, 2021 the assumptions of the Company’s relevant non-financial assets were assessed individually and Management did not identify that any asset may have suffered additional impairment as a result of the economic consequences of the pandemic, in addition to the entries shown in Note 18.4. The most significant entry recorded occurred at the UEG Araucária thermoelectric plant, with the reversal in June 30, 2021 of the entire impairment recognized in previous periods, considering that the estimates of its cash flows are affected by the increase in dispatch from thermal plants, due to unfavorable hydrological conditions associated with operational policies of the National Operator of the Electric System – ONS to guarantee energy supply, including the restoration of the reservoirs of the hydroelectric plants, which makes the plant’s future dispatch assumptions have longer periods than previous projections. In relation to the projections for hydroelectric and wind projects, the main assumptions applied in the preparation of cash flow models did not have a significant impact in the short term, given that most of the energy is already contracted and the amount of energy exposed to Settlement Price of the Differences (PLD) is not significant. In the medium and long term, there was an improvement in the prices practiced in the free market on the portion of non-contracted energy. Finally, in the long term, the expected GSF assumption used to calculate the impairment did not change significantly, accordingly evidencing the recoverability of assets. a.3) Recovery of deferred tax assets The Company has a balance of R$ 963,259 a.4) Fair value of future energy purchase and sale operations The variation in the mark-to-market of electric power purchase and sale agreements occurred mainly due to the increase in the discount rate, which uses as a reference the rate of return of NTN-B disclosed by Anbima. In the medium and long-term, future electric power prices did not change significantly. Therefore, currently, the effects of the pandemic did not have a significant impact on the fair value of the Company’s future energy purchase and sale operations. a.5) Fair value of other assets and liabilities At the present time, the effects of the pandemic did not have a significant impact on the fair value of the Company’s assets and liabilities, mainly on assets originating from concession agreements that are made in the long-term and are contractually guaranteed to receive residual balance at the end of the concession and/ or right to receive cash during the concession. Accordingly, considering that there were no changes in long-term estimates and assumptions, and that the Company’s assets are essential and indicate continuity of operations and cash flows in the medium and long term, up to the present date, its effects did not have a significant impact on the fair value of the Company’s assets and liabilities. a.6) Post-employment benefits The Company’s management has constantly monitored the fair value of the actuarial asset of the post-employment benefit plans due to the instability of the interest rate, which is determined based on market data. Despite the economic instability in this pandemic period, the pension plan surplus remained in 2021 due to the increase in discount rates that reduced the present value of actuarial liabilities and offset the fall in the fair value of financial assets. As shown in Note 24, the benefit plans did not generate additional obligations. a.7) Liquidity The Company has met its expected liquidity ratios and Management believes the financial situation and working capital are within its sufficient requirements. At December 31, 2021, the Company’s net working capital totals R$ 3,209,879 1,753,039 3,472,845 3,222,768 The Company has been monitoring its financial liquidity, considering raising funds and implementing cost reduction actions, with the objective of guaranteeing compliance with financial obligations in due time. a.8) Other assets The Company has not identified any changes in circumstances that indicate impairment of other assets. It should be noted that the Company records changes in sectorial financial assets and liabilities, updated up to the date of the tariff adjustment/review when, the Granting Authority ratifies the transfer on the tariff base and the Company transfers it to the consumer during the next annual cycle, which at Copel occurs as of June 24 of each year. In view of the above, it should be noted that there was no significant or material impact on the Company’s business that could change the measurement of its assets and liabilities presented in the financial statements at December 31, 2021, and until the date of this publication. However, considering that, like all companies, Copel is exposed to risks arising from any legal and market restrictions that may be imposed, it is not possible to ensure that there will be no impact on operations or that the result will not be affected by the future consequences of the pandemic. b) Renegotiation of the Hydrological Risk (Generation Scaling Factor-GSF) On September 9, 2020, Law No. 14,052 was published, which amended Law No. 13,203/2015, establishing new conditions for renegotiating the hydrological risk related to the portion of the costs incurred with the GSF, assumed by the holders of the hydroelectric plants participating in the Energy Reallocation Mechanism (MRE) since 2012, with the worsening of the water crisis. The purpose of the legal amendment was to compensate the owners of the hydroelectric power plants participating in the MRE for non-hydrological risks caused: (i) for generation projects called structuring, related to the anticipation of the physical guarantee, (ii) for the restrictions on the start-up of transmission facilities necessary for the flow of the generation of structuring and (iii) for generation outside the order of merit and import. Such compensation will occur upon the extension of the grant, limited to seven years, and calculated based on the values of the standards applied by Aneel. On December 1, 2020, Aneel Normative Resolution No. 895 was issued, which establishes the methodology for calculating the compensation and the procedures for renegotiating the hydrological risk. To be eligible for the compensation provided for in Law No. 14,052, holders of hydroelectric power plants participating in the MRE must: (i) withdraw any lawsuits whose purpose is the exemption or mitigation of hydrological risks related to the MRE, (ii) waive any allegation and/or new actions in relation to the exemption or mitigation of the hydrological risks related to the MRE, (iii) not having renegotiated the hydrological risk on terms of the Law No. 13.203/2015. In the renegotiation of the hydrological risk, Management exercised its judgment in the development and application of the accounting policy, as provided for in IAS 8 - Accounting Policies, Changes in Accounting Estimates and Errors, using the precepts of IAS 38 by analogy, in order to deal with it is essentially an intangible asset related to the concession right resulting from compensation for costs incurred in previous years. Additionally, considering also by analogy of the referred IAS 38, the constituted asset, in case of renegotiation of the non-hydrological risk, was recognized at fair value, considering the best estimate of the Company.

The authorization right and the deferred tax liability generated in the business combination were recorded in Copel GeT’s investment. In the consolidated balance sheet, these amounts will comprise the balances of intangible assets and deferred income tax and social contribution. The table below shows the consideration transferred for the assets acquired and the goodwill determined as a result of the recognition of the deferred tax liability in the business combination: Consideration amount 597,684 (-) Fair value of net assets acquired 503,463 Goodwill 94,221 The amount paid is supported by the projections of discounted cash flows from the operations of the projects acquired. Of the total consideration, Copel GeT disbursed R$578,236 in November 2021 and the remainder will be paid during the first half of 2022 when prices will also be adjusted in accordance with the contractual provisions. Considering the cash acquired from the subsidiary in the amount of R$76,350, the net effect on the Company’s cash was R$501,886, as shown in the Statements of Cash Flows. Had this business combination been carried out on January 1, 2021, the net operating revenue would have increased by R$78,071, totaling R$24,062,358, and the net income for the year would have increased by R$45,792, totaling R$5,094,394.

On December 7, 2017, the State of Paraná published Complementary Law 205, introducing a new interpretation to the end of the concession that occurred on January 20, 2019. There was an understanding among the shareholders that the law could be challenged and Compagas filed a lawsuit, due to the unconstitutionality of the Law. Provisional protection was granted to Compagas recognizing the validity of the maturity clause provided for in the contract. On December 1, 2020, Supplementary Law No. 227 was issued, revoking article 15 of Supplementary Law No. 205/17, maintaining the expiration of the concession on July 6, 2024. On July 23, 2021, the Secretary of Planning and Structuring Projects of the State of Paraná submitted for public consultation the State Plan for the Piped Gas Distribution Sector, covering the proposal to extend the concession of Compagas for 30 years, counted from July 6, 2024. The proposal includes the execution of a new concession agreement, with a change in the tariff structure of the price concession by cost to a ceiling tariff.

Basis of Preparation	3. Basis of Preparation 3.1 Basis of elaboration The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board, IASB. The Company’s Management believes that all the relevant information used in its management is evidenced in the consolidated financial statements, and that it corresponds to that used by Management in administering the Company. The issuance of these consolidated financial statements was approved by Board of Directors on April 27, 2022. 3.2 Functional and presentation currency The consolidated financial statements are presented in Brazilian Reais, which is the functional and presentation currency of the Company. Balances herein have been rounded to the nearest thousand, unless otherwise indicated. 3.3 Basis of measurement The consolidated financial statements were prepared based on the historical cost, except for certain financial instruments and investments measured at fair value, as described in the respective accounting policies and notes. 3.4 Use of estimates and judgments In the preparation of these consolidated financial statements, Management used judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses of the Company. Actual results may differ from those estimates. Estimates and assumptions are reviewed on a continuous basis. The revisions to the estimates are recognized prospectively . 3.4.1 Judgments Information about judgment referring to the adoption of accounting policies which significantly impacts the amounts recognized in the consolidated financial statements, except those involving estimates, is included in the following notes: · Note 4.1 - Basis of consolidation; and · Note 4.2 - Financial instruments . 3.4.2 Uncertainties over assumptions and estimates Information on uncertainties related to assumptions and estimates with a reasonable possibility of leading to significant adjustments of resulting in a material change within the next financial year is included in the following notes: · Notes 4.3 and 9 - Sectorial financial assets and liabilities; · Notes 4.4 and 10 - Accounts receivable related to the concession · Notes 4.5 and 11 - Contract assets; · Notes 4.8 and 18 - Property, plant and equipment; · Notes 4.9 and 19 - Intangible assets; · Notes 4.10.1 and 7.3 - Expected Credit Losses; · Notes 4.10.2 and 18.4 - Impairment of assets; · Notes 4.11 and 30 - Provisions for litigation and contingent liabilities; · Note 4.12 - Revenue recognition; · Note 4.14 - Power purchase and sale transactions in the Spot Market (Electric Energy Trading Chamber - CCEE); · Note 4.15 - Derivative financial instruments; · Note 4.16.2 and 13.1 - Deferred income tax and social contribution; and · Note 4.17 and 24 – Post-employment benefits. 3.5 Management’s judgment on going concern Management has concluded that there are no material uncertainties that cast doubt on the Company’s ability to continue as a going concern. No events or conditions were identified that may raise significant doubts on its ability to continue as a going concern. The main bases of judgment used for such conclusion are: (i) main activities resulting from long-term concessions; (ii) robust equity; (iii) strong operating cash generation, including financial capacity to settle commitments entered into with financial institutions; (iv) historical profitability; and (v) fulfillment of the objectives and targets set forth in the Company’s Strategic Planning, which is approved by Management, monitored and reviewed periodically, seeking the continuity of its activities.

Significant Accounting Policies

Significant Accounting Policies	12 Months Ended
	Dec. 31, 2021
Significant Accounting Policies	4. Significant Accounting Policies 4.1 Basis of consolidation 4.1.1 Calculation of equity in earnings of investees Investments in joint ventures and associate are recognized in the consolidated financial statements based on the equity method. Under this method, investments are initially recorded at cost and their carrying amount is increased or decreased by the recognition of the investor’s interest in profit, loss and other comprehensive income generated by investees after acquisition. This method must be discontinued from the date the investment ceases to qualify as a jointly controlled or associated company. Payment of dividends decreases the carrying value of investments. When required, for calculation of equity in earnings of investees, the investees’ financial statements are adjusted to align their policies with the Company’s accounting policies. 4.1.2 Subsidiaries The subsidiaries are entities to which the Company is exposed to or has a right over the variable returns arising from its involvement with them and has the ability to affect those returns exerting its power over the entities. The financial statements of the subsidiaries are included in the consolidated financial statements as from the date they start to be controlled by the Company until the date such control ceases. The balances of the subsidiaries’ assets and liabilities, and profit or loss, are consolidated and transactions between consolidated companies are eliminated. The balances of transactions between continuing operations and discontinued operations are also fully eliminated in the consolidated balance sheet. 4.1.3 Noncontrolling interests Noncontrolling interests are presented in equity, separately from the equity attributable to the Company’s shareholders. Profits, losses and other comprehensive income are also allocated separately from the ones allocated to the Company’s shareholders, even if this procedure results in negative noncontrolling interest balance. 4.1.4 Joint ventures and associates Joint ventures are entities over which the Company, subject to an agreement, has the ability to affect returns exerting its power in conjunction with other parties, irrespective of the percentage of interest in the voting capital. Associates are entities over which the Company exerts significant influence regarding financial and operational decisions, without control. When the share in losses of a joint venture or associate equals or exceeds the accounting balance of the investor’s equity interest in the investee, the investor should discontinue the recognition of its share in future losses. Additional losses will be considered, and a liability will be recognized, only if the investor incurs legal or constructive obligations, or performs payments on behalf of the investee. Should the investee subsequently post profits, the investor should resume the recognition of its interest in these profits only subsequent to the point at which the portion to which it is entitled to in these subsequent profits equals its share in unrecognized losses. 4.1.5 Joint operations (consortiums) Joint operation is a joint business according to which parties that jointly control the business have rights on assets and obligations regarding liabilities related to the business. Joint operations are recorded in proportion to the share of interest held in their assets, liabilities and profit or loss. 4.1.6 Business combination The acquisition analysis is done on a case-by-case basis to determine whether the transaction represents a business combination or an asset purchase. Transactions between companies under common control do not constitute a business combination. Assets and liabilities acquired in a business combination are accounted for using the acquisition method and are recognized at their fair value at the acquisition date. The excess of the acquisition cost over the fair value of the net assets acquired (identifiable assets acquired, net of assumed liabilities) is recognized as goodwill in intangible assets. When the amount generated is negative, the bargain purchase gain is recognized directly in profit or loss. The amount paid that refers specifically to the concession right acquired in a business combination where the acquired entity is a concession operator, whose right to the concession has a known and defined term, is not characterized as goodwill. In acquisitions of interests in affiliates and in joint ventures, although they do not constitute a business combination, the net assets acquired are also recognized at fair value. Goodwill is presented in the investment. 4.2 Financial Instruments Financial instruments are recognized immediately on the trade date, that is, when the obligation or right arises. They are initially recorded at fair value, unless it is a trade receivable without a significant financing component, plus, for an item not measured at fair value through profit or loss, any directly attributable transaction costs. An accounts receivable from customers without a significant component of financing is initially measured at the price of the transaction. Fair values ​​are determined based on market prices for financial instruments with active market, and by the present value method of expected cash flows, for those that have no quotation available in the market. After initial recognition, financial assets are only reclassified if the Company changes its business model for managing financial assets and this reclassification must be made prospectively. The Company does not have financial instruments measured at fair value through other comprehensive income. The Company operates with derivative financial instruments as described in The Company’s financial instruments are classified and measured as described below. 4.2.1 Financial assets recorded at fair value through profit or loss Financial assets recorded at fair value through profit or loss include assets classified as held for trading, financial assets designated upon initial recognition as at fair value through profit or loss or financial assets required to be measured at fair value. Financial assets are classified as held for trading if they are acquired for the purpose of being sold or repurchased in the near term. Financial assets with cash flows that are not solely payments of principal and interest are classified and measured at fair value through profit or loss, irrespective of the business model. After initial recognition, transaction costs and attributable interest expenses, when incurred, are recognized through profit or loss. 4.2.2 Financial assets measured at amortized cost These are so classified and measured when: (i) the financial asset is maintained within a business model whose objective is to maintain financial assets in order to receive contractual cash flows; and (ii) the contractual terms of the financial asset give rise, on specified dates, to cash flows that exclusively comprise payments of principal and interest on the principal amount outstanding. 4.2.3 Financial liabilities measured at amortized cost Financial liabilities are measured at amortized cost using the effective interest method. This method is also used to allocate interest expense of these liabilities for the period. The effective interest rate is the rate that discounts estimated future cash flows (including fees paid or received that form an integral part of the effective interest rate, transaction costs and other premiums or discounts) over the expected life of the financial liability or, when appropriate, over a shorter period, for the initial recognition of the net carrying amount. 4.2.4 Financial liabilities measured at fair value through Profit or Loss These are liabilities designated upon initial recognition as at fair value through profit or loss and those classified as held for trading. Financial liabilities designated fair value through profit or loss are stated at fair value with the respective gains or losses in fair value recognized in the statement of income. Net gains or losses recognized in profit or loss include the interest paid on the financial liability. 4.2.5 Derecognition of financial assets and liabilities The Company derecognizes a financial asset when the contractual rights to the cash flows from the financial asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all of the risks and rewards of ownership of the financial asset are transferred or in which the Company neither transfers nor retains substantially all of the risks and rewards of ownership and it does not retain control of the financial asset. The Company derecognizes financial liabilities only when its obligations are discharged, cancelled or settled. The difference between the carrying amount of the derecognized financial liability and the corresponding disbursement made, or to be made, is recorded to profit or loss. 4.3 Net sectorial financial assets and liabilities According to the amendment to the concession agreement of distribution companies, the Company records changes in sectorial financial assets and liabilities, until the next tariff adjustment/review process, when the Concession Grantor approves the transfer as components of the power tariff and thus, it passes the adjustment on to consumers in the next tariff cycle, which occurs on June 24 of each year. The balances of the net sectorial financial assets and liabilities comprise: a) Parcel A Variation Compensation Account - CVA, which records the variation between estimated and actual energy purchase and transmission costs and sector charges, and b) financial items, which correspond to energy over-contracting, neutrality of charges and other rights and obligations included in the tariff. After approval of the Annual Tariff Adjustment and Periodic Tariff Review, the new tariff applied for the tariff year provides for the collection or return of the constituted assets and liabilities. In the event of termination of the concession for any reason, the residual values of Part A items and other financial components not recovered or returned through tariff are incorporated in the calculation of compensation or deducted from unamortized assets indemnity values, thus protecting rights or obligations of the distribution company to the Concession Grantor. 4.4 Accounts receivable related to the concession Refer to financial assets of the concessions with unconditional right to receive cash by the Company, guaranteed by the Concession Grantor by contractual clause and specific legislation. 4.4.1 Power distribution service concession The concession agreement for electricity distribution provides that the users of the public service remunerate part of the investments made by the concessionaire and the Concession Grantor at the end of the concession indemnifies the other party. This model provides for the recognition of financial assets, contract assets in the construction period and intangible assets. The portion recognized as financial asset refers to the indemnity set forth in the public power distribution service concession agreements, which the Company understands as an unconditional right to cash payments from the Concession Grantor upon expiration of the concession. This indemnification aims to reimburse the Company for investments made in infrastructure, without recovery, through the tariff. The cash flows related to these assets are determined taking into account the Regulatory Compensation Basis (Base de Remuneração Regulatória or BRR), defined by the Concession Grantor, and the fair value is recorded based on the replacement cost methodology of the assets included in the distribution infrastructure linked to the concession. 4.4.2 Piped gas distribution service concession Gas concession agreement follows the bifurcated model, whereby part of the investments made by the concession operator is paid by users of the public service and the other part is indemnified by the Concession Grantor, the State of Paraná, at the end of the concession. This model provides for recognition of a financial asset, a contract asset in the construction period and an intangible asset. The amount recognized as a financial asset is the amount that will be indemnified by the Concession Grantor corresponding to the investments made in the last ten years prior to the end of the concession as foreseen in the agreement and that, according to Management, assures the unconditional right to receive cash at the end of the concession. The indemnity assumption is based on the replacement cost of the concession assets. 4.4.3 Bonus for the grant of quota system generation concession agreement The quota system generation concession agreement provides for the payment of a bonus for the grant to the Concession Grantor, pursuant to paragraph 7 of article 8 of Law 12,783/2013. This bonus is recognized as a financial asset because it represents an unconditional right to receive cash, guaranteed by the Concession Grantor during the term of the concession and without risk of demand. The remuneration of this financial asset is based on the Weighted Average Cost of Capital - WACC defined by the National Energy Policy Council (CNPE) in Resolution 2/2015, which is being presented in the statement of income as operating revenue in accordance with the Company’s business model. 4.4.4 Concession of power generation The Company has operated and operates concession agreements for power generation that contain indemnification clauses for the infrastructure not depreciated, amortized and/or received during the concession term. After maturity, the residual balances of the assets is transferred to Accounts receivable related to the concession. At the end of each reporting period, Management evaluates the recoverability of the asset, remeasuring its cash flow based on its best estimate. 4.5 Contract assets Represented by the construction in progress or in service of the infrastructure delegated by the Concession Grantor, conditional upon the receipt of revenue not only by the passage of time, but after fulfilling the performance obligation to maintain and operate the infrastructure. 4.5.1 Power distribution service concession Represents the concessionaire’s contractual right related to the works under construction to meet the needs of the concession, accounted for at cost plus financial charges, when applicable. When the assets are put into operation, the assets are transferred to the intangible asset, in the amount equivalent to what will be remunerated by the user through payment of the fee for the use of the services, or to the accounts receivable associated to the concession, in the amount equivalent to the residual portion of the assets not amortized, which will be reverted to the Concession Grantor through indemnification at the end of the concession. 4.5.2 Power gas distribution service concession Construction in progress for the distribution of piped gas which will be transferred to intangible assets upon their entry in operation and to the extent that the right (authorization) is received to charge the users of the public service. The amount that will not be amortized within the term of the concession is presented in financial assets and indemnified at the end of the concession by the Concession Grantor according to contractual definition. 4.5.3 Power transmission concession Represents the balance of public electricity transmission contracts signed with the Concession Grantor to build, operate and maintain the high voltage lines and substations of the generation centers up to the distribution points. During the term of the concession agreement, the Company receives, subject to its performance, a remuneration denominated Annual Revenue Allowance (RAP) that remunerates the investments made in the construction of the infrastructure and covers also, the costs of operation and maintenance incurred. After the beginning of the commercial operation and insofar as the operation and maintenance service - O&M is provided, the portion of RAP referring to O&M revenue is recognized in profit or loss at fair value, on a monthly basis, and billed together with the revenue part recognized in the construction phase, referring to the remuneration of the built-up assets. This amount billed after complying with the O&M performance is reclassified to the financial asset under Customers until its effective receipt. The Company estimates its revenue in the construction phase at fair value based on the budgeted cost of the work and used by management as a parameter for bidding on the concession auction. Fair value revenue comprises the budgeted cost for the entire construction period plus the construction margin, which represents sufficient profit to cover the costs of managing and monitoring the work. The remuneration rate of each concession is determined by the projection of the expected cost, of the profit margin on the cost in the construction phase and also of the projection of the RAP to be received in the operational stage, already net of the variable consideration estimate (PV) and the RAP part of the O&M performance. This fair value valuation technique using the income approach discounts cash flow for the entire concession period, determining at initial recognition the implied rate that zeroes the flow over time. This remuneration rate is fixed at the initial period and does not change during the performance of the contract and represents the market rate in effect at the time under the conditions of the negotiation between parties. The assets arising from the construction of the transmission infrastructure are formed by the recognition of construction revenue, according to the percentage of completion of the construction (Note 4.13), and by their financial remuneration (Note 4.12.2). The Company recognizes gains and losses due to efficiency or inefficiency in the construction of the infrastructure and due to periodic tariff review (RTP), when incurred, directly in the statement of income for the year. Upon expiration of the concession, any uncollected amounts related to the construction of infrastructure shall be received directly from the Concession Grantor, as an unconditional right to cash reimbursement pursuant to the concession agreement, as compensation for investments made and not recovered through tariffs (RAP). Existing System Basic Network - RBSE The assets that compose the Existing System Basic Network - RBSE include one economic component, referring to the cost of capital of the assets not depreciated in July 2017, and one financial component, resulting from the right for the Annual Permitted Revenue (RAP) of the Concession Agreement No. 060/2001, not received in the period from January 2013 to June 2017, plus monetary adjustment and remuneration interest. 4.6 Accounts payable related to the concession These refer to the amounts set forth in the concession agreement in connection with the right to explore hydraulic power generation potential (onerous concession), whose agreement is signed as Use of Public Property (Uso do Bem Público or UBP) agreements. The obligation is recognized on the date of signature of the concession agreement corresponding to the present value of future cash payments for the concession. The liability is then remeasured using the effective interest rate and reduced by contractual payments. 4.7 Inventories (including property, plant and equipment and contract assets) Materials and supplies in inventory, classified under current assets, and those assigned for investments, classified under property, plant and equipment, and contract assets, have been recorded at their average acquisition cost. Recorded amounts do not exceed their net realizable value. 4.8 Property, Plant and Equipment The property, plant and equipment related to the public service concession agreement are depreciated according to the straight-line method based on annual rates set forth and reviewed periodically by ANEEL, which are used and accepted by the market as representative of the economic useful lives of the assets related to concession’s infrastructure. Property, plant and equipment related to contracts for the use of public property under the independent electricity producer scheme are depreciated based on annual rates established by ANEEL limited to the concession period. All other property, plant and equipment are depreciated using the straight-line method based on estimates of their useful lives, which is reviewed annually and adjusted if necessary. Costs directly attributable to construction works as well as interest and financial charges on borrowings from third parties during construction are recorded under property, plant and equipment in progress, if it is probable that they will result in future economic benefits for the Company. 4.9 Intangible Assets These comprise software acquired from third parties and software developed in-house and are measured at acquisition cost and amortized over five years, besides Intangible assets from Concession Agreements below. 4.9.1 Onerous concession of electric power generation Corresponds to acquisition of exploration rights on hydropower potential whose onerous concession contract is signed as Use of Public Property - UBP. During construction work, this asset is recognized at the present value of future cash disbursements during the Concession Agreement term. When commercial operation starts, the amount starts to be amortized over the concession period. 4.9.2 Hydrological risk renegotiation (Generation Scaling Factor - GSF) Asset consisting of the renegotiation of the hydrological risk under the terms of Law No. 13,203/2015 and subsequent changes, arising from the amounts recovered from the cost with the adjustment of the Energy Reallocation Mechanism - MRE (GSF). The amount was transformed by ANEEL into an extension of the concession period, which is amortized on a straight-line basis until the end of the new concession period, according to note 1-b. 4.9.3 Power distribution service concession This comprises the right to control infrastructure, built or acquired as part of the electric energy public service concession, and the right to charge fees to the users of the public service. Intangible assets are recorded at their fair acquisition and construction value, less accumulated amortization and impairment losses, when applicable. The amortization of intangible assets reflects the pattern in which it is expected that future economic benefits will flow to the Company during the concession period. During the infrastructure construction phase costs are classified as contract assets (Note 4.5). 4.9.4 Piped gas distribution service concession Intangible assets for piped gas distribution services, which correspond to the right to charge users for the gas supply. This intangible asset was initially recognized at acquisition or construction cost, plus interest and other capitalized finance charges. This asset is amortized using the straight-line basis over its estimated useful life, considering the economic benefits generated by intangible assets. During the infrastructure construction phase, costs are classified as contract assets (Note 4.5). 4.9.5 Intangible assets acquired separately Intangible assets with a finite useful life, acquired separately, are recorded at cost, less accumulated amortization and accumulated impairment losses. Amortization is recognized using the straight-line method based on the estimated useful lives of the corresponding assets. The estimated useful lives and the amortization method are reviewed at the end of each reporting period, with the effect of any changes in estimate being accounted for on a prospective basis. 4.9.6 Derecognition of intangible assets An intangible asset is derecognized when no future economic benefits are expected from use or disposal. Gains or losses arising from disposal of an intangible asset are recognized in profit or loss, measured as the difference between net disposal proceeds and the carrying amount of the asset. 4.10 Impairment of assets Assets are assessed to detect evidence of impairment. 4.10.1 Financial assets Provisions for losses on financial assets are based on assumptions about default risk, existing market conditions and future estimates at the end of each year. The Company applies the simplified approach of IFRS 9 to the measurement of expected credit losses for the entire existence of financial assets that do not have significant financing components, by considering a provision for expected loss over a useful life for all trade accounts receivable. To measure expected credit losses, trade accounts receivable is grouped based on shared credit risk characteristics, numbers of days late, in the amount considered enough to cover losses on the realization of these assets, based on specific criteria of the payment history, collection actions carried out for the credit recovery and relevance of the amount due in the receivable portfolio. Trade accounts receivable are written off when there is no reasonable expectation of recovery. Evidence for this includes, among other things, the debtor’s inability to participate in a plan to renegotiate its debt with the Company or to make contractual payments on overdue debts. 4.10.2 Non-financial assets Whenever there is a loss resulting from situations where an asset’s carrying value exceeds its recoverable value, defined as the higher of the asset’s value in use or its net selling price, this loss is recognized in profit or loss for the year. For impairment testing purposes, assets are grouped at the lowest levels for which there are separately identifiable cash flows (Cash Generating Units - CGU). The amount of the impairment of non-financial assets is reviewed at the reporting date. In case of reversal of impairment losses which had been recorded in prior years, this reversal is recognized in current year’s profit or loss. Assets under formation arising from onerous concession and concession rights and/or authorization to generate electricity are classified as intangible assets. Impairment is tested along with the other assets of that cash-generating unit. The Impairment of contract assets in their construction phase are tested immediately, mainly considering the use of the effective interest rate fixed at the beginning of the project and carried to the end of the concession cash flow. After the beginning of the commercial operation, the portion of revenue recognized is tested for impairment in the accounts receivable from customers. For the receivable part conditioned to fulfill the performance obligation to maintain and operate the infrastructure, the Company has no history and no expectation of losses, since amount are subject to guarantee structures, via shared apportionment of eventual default losses among the other members of the national interconnected system managed by the “Operador Nacional do Sistema” (ONS) and by jurisdiction of the sector. 4.11 Provisions Provisions are recognized when: i) the Company has a present obligation (legal, formalized or constructive) resulting from a past event, ii) it is probable (i.e., more likely than not) that an outflow of resources embodying economic benefits will be required to settle the obligation, and iii) a reliable estimate can be made of the amount to settle the obligation. The estimates of outcomes and financial impacts are determined by the Company, which requires use of judgment by Management, supplemented by the experience of similar past transactions and, in some cases, by independent expert reports. Environmental liabilities are recognized as the Company assumes formal obligations before regulatory agencies or becomes aware of potential risks related to environmental issues, which may lead to cash disbursements that are deemed probable and that may be estimated. During the project implementation phase, the accrued amounts are included in property, plant and equipment (generation), construction cost (transmission) or contract assets (distribution). At the start of operations, all costs included in the Operating License, whose programs will be executed during the concession and the respective disbursement has not yet occurred, are measured and adjusted to present value according to the estimated cash flow of disbursements and recorded as environmental provisions matched against the assets related to the project, being adjusted periodically. Once the project enters commercial operation, all costs or expenses incurred with environmental programs related to the project’s operation and maintenance licenses are analyzed according to their nature and included in profit or loss for the period. 4.12 Revenue recognition 4.12.1 Revenue from contracts with customers Revenue is measured based on the consideration that the Company expects to receive in a contract with the customer, net of any variable consideration. The Company recognizes revenues when it transfers control of the product or service to the customer and when it is probable to receive the consideration considering the client’s ability and intention to pay the consideration when due. The Company’s operating revenue comes mainly from the electricity supply and from the electric network availability. The revenue from electricity supply is recognized monthly based on the data for billing that are determined by the average MW of contracted electricity and declared with the CCEE. When the information is not available, the Company estimates the revenue considering the contracts’ rules, the price estimate and the volume provided. For wind power generation companies subject to minimum generation amounts, the Company understands that it is subject to variable consideration, and for this reason, includes a provision for non-performance based on the annual generation estimates, reducing revenue. Revenue from electric power supply and network availability is recognized monthly based on measured and effectively billed energy. In addition, the Company records unbilled revenue, calculated from the period between the last billing and the end of each month, by estimate based on the last measurement taken. In the concession contract for the public electricity distribution service, non-performance compensations are provided for quality indicators that, when incurred, reduce electricity availability revenue. 4.12.2 Interest income Interest income is recognized when it is probable that future economic benefits will flow to the Company and its amount can be reliably measured. Interest income is recognized on a straight-line basis and based on time and the effective interest rate on outstanding principal amounts. The effective interest rate is the one that discounts the estimated future cash receipts calculated during the estimated life of the financial asset in relation to initial net carrying amount of that asset. Regarding the contract assets of the power transmission concession, financial compensation revenue is recognized using the implicit remuneration rate established at the beginning of each project, which is presented in the statement of income as operating income in accordance with the Company’s business model. 4.13 Construction revenues and costs Revenue related to construction services for infrastructure in the power transmission and distribution services, and gas distribution, are recognized over time based on the stage of completion of the work. The respective costs are recognized when incurred, in the statement of income for the year, as construction cost. Given that Copel DIS and Compagas outsource the construction of distribution infrastructure to unrelated parties through works carried out in the short term, the construction margin to the power and gas distribution activities is not material. The construction margin adopted for the transmission activity for the years 2021, 2020 and 2019 was 1.65 4.14 Power purchase and sale transactions in the Spot Market (Electric Energy Trading Chamber - CCEE) Power purchase and sale transactions in CCEE are recorded on the accrual basis of accounting, based on data released by CCEE, which are calculated by the product of the Differences settlement prices - PLD multiplied by the energy surplus declared with CCEE, or, when such information is not available in a timely manner, by an estimate prepared by Management. 4.15 Derivative Financial Instruments 4.15.1 Power purchase and sale transactions The Company negotiates energy purchase and sale agreements and part of its contracts are classified as derivative financial instruments measured at fair value through profit or loss. Unrealized net gains or

On April 6, 2018, the Federal Court of the 1st Region fully granted the preliminary injunction applied for in the interlocutory appeal to suspend the enforcement of any burden or penalty to Copel as a result of noncompliance with the deadlines originally provided for in the Concession Agreement until a final unappealable ruling is rendered. The main action awaits its judgment on merits. The contracted energy of the Colider plant is 125 MW average. For overdue periods the contract was fulfilled and, due to the fact it is awaiting a decision on the merits of the lawsuit, the Company recognized the revenue limited to the financial covenants of the agreement and the regulatory rules, as well as the cost of energy to cover the contractual guarantee. 7.3 Expected credit losses Schedule of allowance for doubtful accounts Balance as of January 1, 2019 Additions / (Reversals) Reversal of write offs Balance as of December 31, 2019 Additions / (Reversals) Reversal of write offs Reclassi- fication (a) Balance as of December 31, 2020 Additions / (Reversals) Reversal of Reclassi- fication (a) Balance as of December 31, 2021 Customers Residential 21,722 71,794 (51,692) 41,824 65,937 (60,365) - 47,396 117,928 (115,056) - 50,268 Industrial 87,197 33,772 (23,015) 97,954 22,487 (31,575) - 88,866 20,413 (66,848) - 42,431 Commercial 69,717 27,866 (26,658) 70,925 29,092 (31,294) - 68,723 35,628 (46,057) - 58,294 Rural 3,810 1,499 (1,920) 3,389 4,788 (4,240) - 3,937 6,407 (7,384) - 2,960 Public Entities 4,874 435 (419) 4,890 9 (1,815) - 3,084 184 (2,887) - 381 Public lighting 120 (117) - 3 20 (15) - 8 11 (8) - 11 Public service 199 145 (79) 265 124 (246) - 143 (16) (154) - (27) Unbilled 1,502 (322) - 1,180 409 - - 1,589 885 - - 2,474 Adjustment to present value (2,883) 1,442 - (1,441) 791 - - (650) (854) - - (1,504) 186,258 136,514 (103,783) 218,989 123,657 (129,550) - 213,096 180,586 (238,394) - 155,288 Concessionaires, Permission holder and Trading Companies CCEE (7.2) 119,665 - - 119,665 - - - 119,665 - - - 119,665 Concessionaries and permission holder 9,474 11,608 (657) 20,425 392 (284) - 20,533 1,224 (1,994) - 19,763 129,139 11,608 (657) 140,090 392 (284) - 140,198 1,224 (1,994) - 139,428 Telecommunications 3,879 13,292 (12,022) 5,149 3,609 (6,260) (2,498) - 3,042 (3,153) 111 - Gas distribution 12,112 1,063 (647) 12,528 238 (509) - 12,257 (2,611) 239 - 9,885 331,388 162,477 (117,109) 376,756 127,896 (136,603) (2,498) 365,551 182,241 (243,302) 111 304,601 (a) Reclassification to Assets classified as held for sale (Note 41).

To be entitled to the bonus, the consumer should reduce his electricity consumption in the months from September to December 2021, in such a way that the total consumptions in this period were at least 10 20 Consumers eligible to receive the bonus are those of low voltage (group B) and medium and high voltage (group A), only from residential, industrial, commercial, services and other activities, rural and public service consumption classes, including those residential consumers that benefit from the Social Electricity Tariff (TSEE). The costs of the Incentive Program for the Voluntary Reduction of Electricity Consumption will be covered by the System Service Charges (ESS), to be passed on by CCEE to the distributors. The Company recorded a credit in the amount of R$ 134,890 For eligible consumers, the bonus will be credited to invoices for January, February and March 2022, and reimbursement to distributors will be made in the CCEE accounting for January, February and March, to be settled in March, April and May of the same year.

These projections were evaluated by the Supervisory Board and approved by the Board of Directors on April 27, 2022. The criteria used for the realization of each item are related to the predictability of realization of the main value that gave rise to the temporary difference. When the expectation of realization of the item is difficult to predict, mainly because it is not under the control of the Company, such as provisions for litigation, the Company adopts history of realization to project its future realization. The realization of the amounts of income tax and social contribution losses follow the potential compensation considering future profits and the limit defined by the legislation. Following are the items that were the basis for the setup of the main credits, as well as their form of realization: - Provisions for post-employment benefits: realized as the payments are made to the Fundação Copel or reversed according to new actuarial estimates; - Provisions for legal claims: realized according to court decisions or by the reversal when the possible risk of the shares is reviewed; - Impairment of assets: realized through the amortization and/or depreciation of the impaired asset; - Provisions for R&D and PEE: realized through the expenses incurred in the projects carried out; - Deemed cost: realized through the amortization and/or depreciation of the valued asset; - Amounts related to the concession agreement: realized over the term of the agreement; - Amounts related to tax losses and negative tax basis: recovered by offsetting against future taxable income; - Other amounts: realized when they meet the deductibility criteria provided for in tax legislation, or upon reversal of the recorded amounts. The projected realization of the deferred taxes is shown below: Assets Liabilities 2022 388,826 (161,407) 2023 144,103 (268,255) 2024 145,942 (273,502) 2025 105,389 (194,576) 2026 98,634 (167,543) 2027 to 2029 226,560 (419,476) 2030 to 2031 931,163 (957,427) 2,040,617 (2,442,186) 13.1.2 Unrecognized tax credits As of December 31, 2021, Company did not recognize income tax and social contribution credits on income tax and social contribution tax losses in the amount of R$ 68,826 131,655 Summary Of Other Recoverable Taxes And Other Taxes 13.2 Other taxes recoverable and other tax obligations 12.31.2021 12.31.2020 Current assets Recoverable ICMS (VAT) 111,101 89,942 Recoverable PIS/Pasep and Cofins taxes (a) 1,396,645 1,474,119 Other recoverable taxes 1,118 1,262 1,508,864 1,565,323 Noncurrent assets Recoverable ICMS (VAT) 141,951 84,376 Recoverable PIS/Pasep and Cofins taxes (a) 2,967,756 4,421,403 Other recoverable taxes 33,839 33,719 3,143,546 4,539,498 Current liabilities ICMS (VAT) payable 290,627 201,138 PIS/Pasep and Cofins payable 42,340 179,133 IRRF on interest on capital 33,592 43,950 Special Tax Regularization Program - Pert 52,168 50,565 Other taxes 22,206 15,822 440,933 490,608 Noncurrent liabilities Social security contributions - injunction on judicial deposit 220,108 209,145 Special Tax Regularization Program - Pert 369,526 408,738 Other taxes 5,176 4,600 594,810 622,483 (a) The balance contains amounts referring Pis and Cofins credit on ICMS (Note 13.2.1) 13.2.1 Pis and Cofins credit on ICMS Copel Distribuição On August 12, 2009, Copel DIS filed for writ of mandamus No. 5032406-35.2013.404.7000 with the 3rd Federal Court of Curitiba applying for the granting of an order to stop including ICMS in the PIS and Cofins tax base, as well as to authorize it to proceed with the administrative offsetting of the amounts collected more than due for such social contributions in the last five years. On June 16, 2020, a final unappealable ruling was handed down by the 2nd Panel of the Federal Regional Court of the 4th Region recognizing Copel DIS’s right to exclude from the PIS and Cofins tax base the full amount of ICMS included in the energy supply and distribution invoices. The ruling also recognized that the limitation period, in this case, is of five years and that, therefore, Copel has the right to recover the amounts that have been paid during the five years preceding the filing of the writ of mandamus until the date of the final unappealable ruling. Considering the final and unappealable ruling, with a favorable decision for the Company, the entry of economic benefits became virtually certain and, therefore, the asset became realizable. In view of these, Copel DIS recognized the updated tax credit in assets, which will be recovered by offsetting against taxes payable within the statute of limitations period. Additionally, with the assistance of the opinion of its legal counsel, the Company concluded to record the liability to be refunded to consumers for the last 10 years of the credit, as from the date of the unappealable ruling, considering the current legislation, the statute of limitations period defined in the civil code and the jurisprudence of the courts. The refund of PIS and Cofins credits to consumers awaits the conclusion of discussions with Aneel regarding compensation mechanisms and criteria, based on the effective compensation of tax credits, which began in June 2021 with authorizations from the Federal Revenue of Brazil of the credit originating from Cofins. On February 09, 2021, Aneel opened a public consultation aimed at discussing how to return tax credits to consumers, as described in Note 30.2. Aneel’s proposal is the return of the amounts through a rebate in the electricity bill in each Tariff Cycle (credits with Federal Revenue of Brazil, plus any judicial deposits already received by the concessionaire/permissionaire), allocated according to its consumer class, with shares being defined for each of them at each billing cycle, so that their participation in monthly billing is taken into account. There was also no manifestation by Aneel regarding the statute of limitations for returning the credit to the consumer. Also, on February 09, 2021, Aneel published Aneel Dispatch No. 361, establishing that, in exceptional situations, in which there is a possibility of a significant tariff increase, prior to the conclusion of a Public Consultation No. 005/2021, part of the PIS and Cofins credits may be utilized in offsetting the tariff increase, limited to 20% (twenty percent) of the total involved in lawsuits filed by distributors. Considering Aneel Dispatch nº 361/2021, in tariffs readjusted as of June 24, 2021, by means of Ratifying Resolution No. 2,886, R$702,000 were used as a financial item, reducing consumer tariffs in the next twelve months. However, in the tariff process, the Company expressed the right to claim, if necessary, future tariff adjustments to equalize any financial differences observed between the amounts considered herein and the amounts effectively recovered from tax credits, as well as other rights it deems necessary. On May 13th, 2021, the Supreme Court concluded the judgment of the opposing motion for clarification filed by the Federal Government in Extraordinary Appeal 574.706/PR, partially granting it in the following terms: (i) relating to ICMS excluded from the calculation basis of PIS/Cofins contributions, prevailed the detached ICMS method; and (ii) modulate the effects of the judgment whose production will take place after March 15, 2017, except for the judicial and administrative actions filed up to the date of the session in which the judgment is delivered. Therefore, the final decision on this matter did not impact the final and unappealable decision in favor of the Company, maintaining the treatment and amounts recorded. The table below shows the impacts of these records on Copel’s statement of financial position and statement of income: Schedule of Balance Sheet and statement of income 12.31.2021 12.31.2020 Tax credit - principal 2,949,943 3,620,118 Tax credit - monetary update 1,405,322 2,035,636 Effect on assets 4,355,265 5,655,754 Pis/Pasep and Cofins to be refunded to consumers (3,905,398) (3,805,985) (-) Transfer to sectorial financial liabilities 578,603 Tax liabilities - Pis/Pasep and Cofins payable on financial income (94,657) Income tax and social contribution (596,738) Effect on liabilities (3,326,795) (4,497,380) EFFECT ON STATEMENT OF FINANCIAL POSITION 1,028,470 1,158,374 Net operating revenue 810,563 Financial income, net of pis and cofins 21,640 944,549 Income tax and social contribution (7,358) (596,738) EFFECT ON THE INCOME STATEMENT 14,282 1,158,374 In addition, as mentioned above, in the Tariff Review process of Copel DIS of 06.24.2021, the amount of R$702,000 was transferred to the Sector Financial Liability account, of which R$578,603 referring to the portion of tax credits to be returned to the consumer and R$123,397 that were recorded in the PIS and Cofins account to be refunded to consumers.

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. The projects with impairment balances recorded at December 31, 2021 are the following: Schedule of impairment balances Property, Plant and Equipment Value in use Cost Depreciation Impairment HPP Colíder 2,489,116 (259,065) (639,529) 1,590,522 Consórcio Tapajós (a) 14,879 - (14,879) Power plants in Paraná 1,024,841 (109,524) (243,483) 671,834 3,528,836 (368,589) (897,891) 2,262,356 (a) Project under development The table below shows the changes in the impairment for the year: S chedule of impairment of property plant and equipment Balance as of Impairment / Reversal Balance as of Impairment / Reversal Balance as of January 1, 2020 December 31, 2020 December 31, 2021 In service UHE Colíder (777,294) 94,101 (683,193) 43,664 (639,529) Wind power complex Cutia (54,104) 54,104 - - UEGA (138,777) (138,777) 138,777 - Power plants in Paraná (129,779) 26,228 (103,551) 32,571 (70,980) (961,177) 35,656 (925,521) 215,012 (710,509) In progress Consórcio Tapajós (14,464) (14,464) (415) (14,879) Power plants in Paraná (107,797) 1,953 (105,844) (66,659) (172,503) (122,261) 1,953 (120,308) (67,074) (187,382) (1,083,438) 37,609 (1,045,829) 147,938 (897,891) 18.4.1 UHE 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. 18.4.2 Wind 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. 18.4.3 UEG 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. 18.4.4 Figueira 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 5.70 18.4.5 Other 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 5.70 18.4.6 Cash-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 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. 18.5.2 Jandaíra Wind Complex With estimated investment of R$ 411,610 with installed capacity of 90.1 MW and physical guarantee of 47.6 MW average 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 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. 18.6 Depreciation rates Schedule of average depreciation rates Depreciation rates (%) 12.31.2021 12.31.2020 12.31.2019 Average generation segment rates (Note 18.8.1) General equipment 6.25 6.26 6.33 Machinery and equipment 3.68 3.39 3.67 Generations 3.42 3.73 3.38 Reservoirs, dams and ducts 2.56 2.68 2.50 Hydraulic turbines 2.90 2.93 0.29 Gas and steam turbines - 2.00 2.00 Water cooling and treatment 4.00 4.00 4.00 Gas conditioner 4.00 4.00 4.00 Wind power plant unit 4.98 4.94 5.49 Buildings 3.15 3.15 - Average rates for central government assets Buildings 3.33 3.35 3.35 Machinery and office equipment 6.27 6.25 6.25 Furniture and fixtures 6.30 6.25 6.25 Vehicles 14.29 14.29 14.29 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. 18.6.1 Assets 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.

Provisions for Legal Claims and Contingent Liabilities	30. Provisions for Legal Claims and Contingent Liabilities The Company is responsible for several legal and administrative proceedings before different courts. Based on assessments made by the Company’s legal counsel, Management makes provisions for legal claims in which the losses are rated probable, when the criteria for recognition of provisioning, described in Note 4.11, are met. The Company’s management believes it is impracticable to provide information regarding the timing of any cash outflows related to the lawsuits for which the Company is responsible on the date of preparation of the financial statements, in view of the unpredictability and dynamics of the Brazilian judicial, tax and regulatory systems, and that the final resolution depends on the conclusions of the lawsuits. For this reason, this information is not provided. 30.1 Change in provision for legal claims Schedule of changes in provisions for litigation Income Provision Construction Transfers/ Balances as of Balances as of for litigations cost Additions Others December, 31 January 1, 2021 Additions Reversals Additions to assets Settlements (a) 2021 Tax Cofins 107,148 4,123 (1,212) - 110,059 Others 66,725 10,046 (205) - (127) (5,383) 71,056 173,873 14,169 (1,417) - (127) (5,383) 181,115 Labors 596,248 94,845 (21,647) - (105,777) 6,087 569,756 Employee benefits 52,401 4,685 (19,623) - (761) 446 37,148 Civil Civil and administrative claims 387,895 129,730 (9,218) - (74,989) 19 433,437 Easements 111,553 1,616 15,702 36,771 (27,573) 138,069 Expropriations and property 133,888 680 (15,031) (7,268) 12,943 (184) 125,028 Customers 3,973 895 (706) - (407) 3,755 Environmental 7,174 4,992 (4,964) - (1,300) 5,902 644,483 137,913 (29,919) 8,434 49,714 (103,153) (1,281) 706,191 Regulatory 88,699 20,694 (5,971) - (267) 103,155 1,555,704 272,306 (78,577) 8,434 49,714 (210,085) (131) 1,597,365 (a) Reclassification mainly to Liabilities associated with assets classified as held for sale (Note 41).

An appeal has been brought by ANEEL, pending judgment by the Federal Court of the 1st Region. The practical consequence of the ruling was, at the time it exempted ESBR, to expose the distributors with whom it entered into power trading contracts (CCEARs) to the Short-Term Market and to the high value of the Settlement Price of the Differences (Preço de Liquidação das Diferenças - PLD, in Portuguese) in the period, including Copel DIS. This occurred because the rules for the sale of electricity require that all energy consumed should have a corresponding contractual coverage.

Determining fair values a) Equivalent to their respective carrying values due to their nature and terms of realization. b) Fair value is calculated based on information made available by the financial agents and the market values of the bonds issued by the Brazilian government c) The criteria are disclosed in Note 4.4 to these financial statements. d) The fair values of generation assets approximate their carrying amounts, according to Note 4.4 to these financial statements. e) The fair values of assets and liabilities are equivalent to their carrying amounts according to Note 4.15 to these financial statements. f) Investments in other companies, stated at fair value, which is calculated according to the price quotations published in an active market, for assets classified as level 1 and determined in view of the comparative assessment model for assets classified as level 2. g) The cost of the last issue of Copel’s debentures, CDI + 1.38%, is used as a basic assumption for discount of the expected payment flows. h) The Company based its calculation on the comparison with a long-term and post-fixed National Treasury Bond (NTN-B) maturing on August 15, 2026, which yields approximately 3.87% p.a. plus the IPCA inflation index. i) Receivables related to the concession agreement for providing electricity generation services under quota arrangements, having their fair value calculated by expected cash inflows, discounted at the rate established by ANEEL auction notice 12/2015 (9.04%). j) Calculated from the Unit Price quotation (PU) for December 31, 2021, obtained from the Brazilian Association of Financial and Capital Markets (ANBIMA), net of unamortized financial cost. k) Actual net discount rate of 8.75% p.a., in line with the Company’s estimated rate for long-term projects. 36.2 Financial risk management The Company’s business activities are exposed to the following risks arising from financial instruments: 36.2.1 Credit risk Credit risk is the risk of the Company incurring losses due to a customer or counterparty in a financial instrument, resulting from failure in complying with their contractual obligations. Exposure to credit risk 12.31.2021 12.31.2020 Cash and cash equivalents (a) 3,472,845 3,222,768 Bonds and securities (a) 361,058 300,530 Pledges and restricted deposits linked (a) 142,946 133,718 Trade accounts receivable (b) 4,515,426 3,819,680 CRC Transferred to the Paraná State Government (c) 1,392,624 Sectorial financial assets (d) 767,480 346,930 Accounts receivable - distribution concession (e) 1,433,734 1,149,934 Accounts receivable - concessions - Bonus from the grant (f) 730,851 671,204 Accounts receivable - generation concessions (g) 102,220 81,202 Other temporary investments (h) 19,985 22,385 11,546,545 11,140,975 a) The Company manages the credit risk of its assets in accordance with the Management’s policy of investing virtually all of its funds in federal banking institutions. As a result of legal and/or regulatory requirements, in exceptional circumstances the Company may invest funds in prime private banks. b) The risk arises from the possibility that the Company might incur losses resulting from difficulties to receive its billings to customers. This risk is directly related to internal and external factors to Copel. To mitigate this type of risk, the Company manages its accounts receivable, detecting the classes of consumers most likely to default, implementing specific collection policies and suspending the supply and/or recording of energy and the provision of service, as established in contract and regulatory standards. c) There is no risk considering that the balance was settled in 2021. d) Management considers the risk of this credit to be reduced, since the agreements signed guarantee the unconditional right to receive cash at the end of the concession to be paid by the Concession Grantor, corresponding to the costs not recovered through the tariff. e) Management considers the risk of this credit to be reduced, since the agreements signed guarantee the unconditional right to receive cash at the end of the concession to be paid by the Concession Grantor, referring to investments in infrastructure not recovered through the tariff. f) Management considers the risk of such credit to be low, as the contract for the sale of energy by quotas guarantees the receipt of an Annual Generation Revenue - RAG, which includes the annual amortization of this amount during the concession term. g) For the generation concession assets, ANEEL published Normative Resolution 596/2013, which deals with the definition of criteria for calculating the New replacement value (Valor novo de reposição – VNR), for the purposes of indemnification. In July 2021, Normative Resolution No. 942/2021 was published, regulating the calculation of these amounts through the presentation of appraisal reports to be prepared by accredited companies. Management’s expectation of indemnification for these assets supports recoverability of the balances recorded. h) This risk arises from the possibility that the Company might incur losses resulting from the volatility on the stock market. This type of risk involves external factors and has been managed through periodic assessment of the variations occurred in the market. 36.2.2 Liquidity risk The Company’s liquidity risk consists of the possibility of having insufficient funds, cash or other financial assets, to settle obligations on their scheduled maturity dates. The Company manages liquidity risk relying on a set of methodologies, procedures and instruments applied to secure ongoing control over financial processes to ensure proper management of risks. Investments are financed by incurring medium and long-term debt with financial institutions and capital markets. Short, medium and long-term business projections are made and submitted to Management bodies for evaluation. The budget for the next fiscal year is annually approved. Medium and long-term business projections cover monthly periods over the next five years. Short-term projections consider daily periods covering only the next 90 days. The Company permanently monitors the volume of funds to be settled by controlling cash flows to reduce funding costs, the risk involved in the renewal of loan agreements and compliance with the financial investment policy, while concurrently keeping minimum cash levels. The following table shows the expected undiscounted settlement amounts in each time range. Projections were based on financial indicators linked to the related financial instruments and forecast according to average market expectations as disclosed in the Central Bank of Brazil’s Focus Report, which provides the average expectations of market analysts for these indicators for the current year and for the next 3 years. As from 2026, 2025 indicators are repeated on an unaltered basis throughout the forecast period.

As disclosed in Notes 22.5 and 23.3, the Company has loans and financing agreements and debentures with covenants that if breached may have their payment accelerated. 36.2.3 Market risk Market risk is the risk that the fair value or the future cash flows of a financial instrument shall oscillate due to changes in market prices, such as currency rates, interest rates and stock price. The purpose of managing this risk is to control exposures within acceptable limits, while optimizing return. a) Foreign currency risk (US Dollar) This risk comprises the possibility of losses due to fluctuations in foreign exchange rates, which may reduce assets or increase liabilities denominated in foreign currencies. The Company’s foreign currency indebtedness is not significant, and it is not exposed to foreign exchange derivatives. The Company monitors all relevant foreign exchange rates. The effect of the exchange rate variation resulting from the power purchase agreement with Eletrobras (Itaipu) is transferred to customers in Copel DIS’s next tariff adjustment. The exchange rate risk posed by the purchase of gas arises from the possibility of Compagas reporting losses on the fluctuations in foreign exchange rates, increasing the amount in Reais of the accounts payable related to the gas acquired from Petrobras. This risk is mitigated by the monitoring and transfer of the price fluctuation through tariff, when possible. The Company monitors these fluctuations on an ongoing basis. Sensitivity analysis of foreign currency risk The Company has developed a sensitivity analysis in order to measure the impact of the devaluation of the US dollar on its loans and financing subject to currency risk. The valuation of the financial instruments considers the possible effects on profit and loss and equity of the risks evaluated by the Company’s Management on the reporting date for the financial instruments, as recommended by IFRS 7 - Financial Instruments: Disclosure. Based on the equity position and the notional value of the financial instruments outstanding at the date of these financial statements, it is estimated that these effects will approximate the amounts stated in the above table in the column for the forecast probable scenario, since the assumptions used by the Company are similar to those previously described. The baseline scenario takes into account the existing balances on the date of these financial statements and the probable scenario assumes a variation in the foreign exchange rate - prevailing at the end of the period (R$/US$5.50) based on the median market expectation for 2022 according to the Focus Report of February 18, 2022, issued by the Central Bank of Brazil, with the exception of the amounts related to the STN, which for the probable scenario considered the balances effectively realized, since the operation was settled on March 10, 2022. Additionally, the Company continues to monitor scenarios 1 and 2, which consider a deterioration of 25% and 50%, respectively, in the main risk factor of the financial instrument in relation to the level used in the probable scenario, as a result of extraordinary events that may affect the economic scenario.

Probable value reflects the settlement value of the transaction, which took place on March 10, 2022. b) Foreign exchange risk - euro This risk arises from the possibility of loss due to fluctuations in exchange rates affecting fair value of Non-Deliverable Forward (NDF) transactions. These derivatives were contracted considering that in the supply contracts for wind turbines of companies in the Jandaíra wind complex, controlled by Copel GeT, disbursement installments in Euro are foreseen. Sporadic gains and losses are recognized in the Company’s statement of income. Based on the notional amount of €2.200 outstanding at the date of these financial statements, the fair value was estimated by the difference between the amounts contracted under the respective terms and the forward currency quotations (B3 reference rates), discounted to present value at the fixed rate. The net asset balance recorded is shown in Note 12. Sensitivity analysis of operations with derivative financial instruments The Company developed a sensitivity analysis in order to measure the impact from exposure to fluctuation in exchange rate to Euro (€). For the base scenario, the accounting balances recorded on the date of these financial statements were considered and for the probable scenario, the balances effectively carried out.

Probable value reflects the settlement value of the transaction, which took place on March 10, 2022. c) Interest rate and monetary variation risk This risk comprises the possibility of losses due to fluctuations in interest rates or other indicators, which may reduce financial income or increase the financial expenses related to the assets and liabilities raised in the market. The Company has not entered into derivative contracts to cover this risk but has been continuously monitoring interest rates and market indexes in order to observe any need for contracting. Sensitivity analysis of interest rate and monetary variation risk The Company has developed a sensitivity analysis in order to measure the impact of variable interest rates and monetary variations on its financial assets and liabilities subject to these risks. The valuation of the financial instruments considers the possible effects on profit and loss and equity of the risks evaluated by the Company’s Management on the reporting date for the financial instruments, as recommended by IFRS 7 - Financial Instruments: Disclosure. Based on the equity position and the notional value of the financial instruments outstanding at the date of these financial statements, it is estimated that these effects will approximate the amounts stated in the above table in the column for the forecast probable scenario, since the assumptions used by the Company are similar to those previously described. The baseline scenario takes into account the existing balances on the date of these financial statements and the probable scenario assumes balances reflecting varying indicators (CDI/Selic - 12.25%, IPCA - 5.56%, IGP-DI - 8.09%, IGP-M - 8.12% and TJLP - 6.55%) estimated as market average projections for 2022 according to the Focus Report of February 18, 2022, issued by the Central Bank of Brazil, except IGP-DI and TJLP that considers the Company’s internal projection. Additionally, the Company continues to monitor scenarios 1 and 2, which consider a deterioration of 25% and 50%, respectively, in the main risk factor of the financial instrument in relation to the level used in the probable scenario, as a result of extraordinary events that may affect the economic scenario.

(13,447,298) (1,296,444) (1,620,557) (1,944,669) (a) Risk assessment still requires ruling by the Concession grantor. 36.2.4 Electricity shortage risk Approximately 64% of installed capacity in Brazil currently comes from hydroelectric generation, as informed by the Generation Information Bank of ANEEL, which makes Brazil and the geographic region in which we operate subject to unpredictable hydrological conditions, due to non-cyclical deviations of mean precipitation. Unsatisfactory hydrological conditions may cause, among other things, the implementation of comprehensive programs of electricity savings, such as rationalization or even a mandatory reduction of consumption, which is the case of rationing. From September 2020, the National Interconnected System has been presenting the worst record of Affluent Natural Energies in the aggregate of its uses. The Ministry of Mines and Energy and other sector bodies are working to mitigate the risks of rationing, with emphasis on a high thermoelectric dispatch outside the order of cost merit, as well as the relaxation of restrictions on the system’s hydroelectric operation. Additionally, considering the strong wind generation in the Northeast and the generation of biomass in the Southeast, it is estimated that the risk of energy shortages in 2021 and 2022 will be minimized, according to official information published so far. In order to mitigate the risk of meeting instant demand, the MME is managing large energy consumers in order to migrate their consumption from periods of greater demand. Which, in general, means moving production into the early morning hours. This guarantees the service to consumers with greater economy, since the operation in periods of high demand is very expensive. The Electric Sector Monitoring Committee (CMSE) has maintained the energy deficit risk indicators within the safety margin in short-term projections, with the authorization of a reduced dispatch of thermal generation outside the order of merit of cost by ONS, which for in turn, it has dispatched the amounts necessary for a safe operation to the National Interconnected System. Although dam storage levels are not ideal, from the standpoint of the bodies responsible for planning the operation of the system, when combined with other variables, such as affluent flows, wind and solar generation, they are sufficient to keep the risk of deficit within the safety margin established by the National Energy Policy Council (CNPE) in all subsystems (maximum risk of 5%). 36.2.5 Risk of GSF impacts The Energy Reallocation Mechanism (Mecanismo de Realocação de Energia - MRE, in Portuguese) is a system of redistribution of electric power The contracts need to have an energy physical guarantee basis. This is done, especially, through the allocation of power generated received from the MRE or purchase. The GSF is the ratio of the entire hydroelectric generation of the MRE participants to the GF sum of all the MRE plants. Basically, the GSF is used to calculate how much each plant will receive from generation to back up its GF. Thus, knowing the GSF of a given month the company will be able to know if it will need to back up its contracts through purchases. Whenever GSF multiplied by GF is less than the sum of contracts, the company will need to buy the difference in the spot market. However, whenever GSF multiplied by GF is greater than the total contracts, the company will receive the difference to the PLD. The low inflows that have been recorded since 2014, as well as problems with delays in the expansion of the transmission system have resulted in low GSF values, resulting in heavy losses for the companies holding MRE participating hydroelectric projects. For plants with contracts in the Free Contracting Environment - ACL, the main way to manage the low GSF risk is not to compromise the entire GF with contracts, as well as the timely repurchase of intra-annual energy approaches currently adopted by the Company. For the contracts in the ACR, Law 13,203/2015 allowed the generators to contract insurance for electricity demand (load), by means of payment of a risk premium. Copel adopted this approach to protect contracts related to energy generated by the Mauá, Baixo Iguaçu and Colíder Thermoelectric Plants and Cavernoso II Small HPP. For the distribution segment, the effects of the GSF are perceived in the costs associated with quotas of Itaipu, of Angra and the plants whose concessions were renewed in accordance with Law 12,783/2013, as well as in the costs of the contracts for power availability with thermoelectric plants. This is a financial risk, since there is guarantee of neutrality of expenses with energy purchases through a tariff transfer. 36.2.6 Risk of non-renewal of concessions - generation and transmission The extension of energy generation and transmission concessions, achieved by Law No. 9,074/1995, is regulated by Law No. 12,783/2013, which was amended by Law No. 14,052/2020, regarding the deadline for requesting an extension of concessions. According to the new law, the concession operator should request extension of concession at least 36 months before the final contract date or after granting of concessions to hydroelectric power generation and electric power transmission and distribution plants, and of up to 24 months for thermoelectric plants. The Concession Grantor may advance effects of extension by up to 60 months counted as of contract or grant date and may also define initial tariff or revenue, which includes the definition of the tariff or initial revenues for the generation and transmission ventures (RAG - Annual Generation Revenue and RAP - Permitted Annual Revenue, respectively). Concessions for hydroelectric power generation and electric power transmission may be extended, at the discretion of the granting authority, only once, for a period of up to 30 years. Thermoelectric power generation concessions have an extension term limited to 20 years. In 2019, Decree No. 10,135/2019 was published, which regulated the granting of concession contracts in the electricity sector associated with privatization through sale of control by holder of a public service concession for electricity generation, having as one of the conditioning factors the alteration of the exploration regime to Independent Power Producer (IPP). According to the Decree, the manifestation of sale of the concession must take place within up to 42 months from the date of the related formal agreement, and any sale must take place within up to 18 months from the concession end date. If sale of control of the venture does not occur within the specified period, the plant must be subject to auction by the granting authority and the same concessionaire can participate in the auction, if it meets the qualification conditions. Compensation was established through the extension of the concession period of the plants contemplated by Law No. 13,203/2015, ratification of the period of extension of the concession of these plants through Ratification Resolutions No. 2919/2021 and No. 2932/2021 (Note 1-b). For HPP Governador Bento Munhoz da Rocha Netto - HPP GBM (1,676 MW), whose concession will end in 2024, the Company has not expressed any interest in extending the concession, as internal studies have shown that the extension through early change of the exploration regime would be economically and financially disadvantageous in relation to exploration of the plant under the current regime until concession end. On March 3, 2020, Copel GeT transferred the concession of HPP GBM to subsidiary F.D.A. Geração de Energia Elétrica S.A. with the purpose of, if the studies carried out by Copel GeT point to the advantage of the operation, divesting the control of this concessionaire and, thus, allow a new concession grant for 30 years. With respect to HPP São Jorge, whose concession ends in 2026, Copel did not express interest in the renewal and intends, at the end of the concession, to request ANEEL to convert the granting of concession into granting of registration. Regarding the Figueira HPP concession, expired in March 2019, the Company awaits the conclusion of the related ANEEL and MME procedural steps to execute any amendment to the Concession Agreement. The plant is undergoing a modernization process and will have as direct benefits the improvement in energy efficiency and the reduction of pollutant emissions in the atmosphere, in comparison with the old plant. According to the new law, the Company may express its intention to extend the concession of the Apucaraninha HPP until January 2024, and the Guaricana and Chaminé HPPs until July and August, 2025, respectively. If the Company does not express an interest in the extension of the current regime at its final term, be granted to the Company in the condition of registration, and the other concessions, at their final term, must be returned to the Concession Grantor. Copel GeT has no transmission concession to expire in the next ten years. 36.2.7 Risk on non-renewal of concessions – distributions of electricity The fifth amendment to Copel DIS’s concession contract No. 46/1999 imposes economic and financial efficiency covenants and indicators that consider the duration and frequency of service interruptions (DECi and FECi).

An appeal has been brought by ANEEL, pending judgment by the Federal Court of the 1st Region. The practical consequence of the ruling was, at the time it exempted ESBR, to expose the distributors with whom it entered into power trading contracts (CCEARs) to the Short-Term Market and to the high value of the Settlement Price of the Differences (Preço de Liquidação das Diferenças - PLD, in Portuguese) in the period, including Copel DIS.

Determining fair values a) Equivalent to their respective carrying values due to their nature and terms of realization. b) Fair value is calculated based on information made available by the financial agents and the market values of the bonds issued by the Brazilian government c) The criteria are disclosed in Note 4.4 to these financial statements. d) The fair values of generation assets approximate their carrying amounts, according to Note 4.4 to these financial statements. e) The fair values of assets and liabilities are equivalent to their carrying amounts according to Note 4.15 to these financial statements. f) Investments in other companies, stated at fair value, which is calculated according to the price quotations published in an active market, for assets classified as level 1 and determined in view of the comparative assessment model for assets classified as level 2. g) The cost of the last issue of Copel’s debentures, CDI + 1.38%, is used as a basic assumption for discount of the expected payment flows. h) The Company based its calculation on the comparison with a long-term and post-fixed National Treasury Bond (NTN-B) maturing on August 15, 2026, which yields approximately 3.87% p.a. plus the IPCA inflation index. i) Receivables related to the concession agreement for providing electricity generation services under quota arrangements, having their fair value calculated by expected cash inflows, discounted at the rate established by ANEEL auction notice 12/2015 (9.04%). j) Calculated from the Unit Price quotation (PU) for December 31, 2021, obtained from the Brazilian Association of Financial and Capital Markets (ANBIMA), net of unamortized financial cost. k) Actual net discount rate of 8.75% p.a., in line with the Company’s estimated rate for long-term projects.

As a result of legal and/or regulatory requirements, in exceptional circumstances the Company may invest funds in prime private banks. b) The risk arises from the possibility that the Company might incur losses resulting from difficulties to receive its billings to customers. This risk is directly related to internal and external factors to Copel. To mitigate this type of risk, the Company manages its accounts receivable, detecting the classes of consumers most likely to default, implementing specific collection policies and suspending the supply and/or recording of energy and the provision of service, as established in contract and regulatory standards. c) There is no risk considering that the balance was settled in 2021. d) Management considers the risk of this credit to be reduced, since the agreements signed guarantee the unconditional right to receive cash at the end of the concession to be paid by the Concession Grantor, corresponding to the costs not recovered through the tariff. e) Management considers the risk of this credit to be reduced, since the agreements signed guarantee the unconditional right to receive cash at the end of the concession to be paid by the Concession Grantor, referring to investments in infrastructure not recovered through the tariff. f) Management considers the risk of such credit to be low, as the contract for the sale of energy by quotas guarantees the receipt of an Annual Generation Revenue - RAG, which includes the annual amortization of this amount during the concession term. g) For the generation concession assets, ANEEL published Normative Resolution 596/2013, which deals with the definition of criteria for calculating the New replacement value (Valor novo de reposição – VNR), for the purposes of indemnification. In July 2021, Normative Resolution No. 942/2021 was published, regulating the calculation of these amounts through the presentation of appraisal reports to be prepared by accredited companies. Management’s expectation of indemnification for these assets supports recoverability of the balances recorded. h) This risk arises from the possibility that the Company might incur losses resulting from the volatility on the stock market. This type of risk involves external factors and has been managed through periodic assessment of the variations occurred in the market.

[1]	The variation in provisions for legal claims occurred due to the review of the assessment of the Company’s legal advisors, mainly in civil claims. The details of the actions are shown in Note 30.
[2]	The contracts between Petrobras and Compagás were offset by the volume of 55,770,890 m³, disregarding the difference in gas pricing between the contracts (NE 12.1). However, the parties have not reached a consensus to this date, and the amount of R$15,688 remains in dispute. In view of the compensation made by Petrobras and the uncertainty in the reimbursement of the difference in Brazilian reais of the referred Assignment, impairment was recorded for this amount until the end of the transaction.

Description	ESBR filed Ordinary Lawsuit No. 10426-71.2013.4.01.4100 against ANEEL in the Federal Court of Rondônia, whose ruling: (i) acknowledged the exclusion of liability for the 535-day schedule overrun in the construction of the Jirau Hydropower Station; (ii) declares any obligations, penalties and costs imposed on ESBR as a result of the schedule overrun to be unenforceable, and (iii) annuls ANEEL Resolution 1,732/2013, which had recognized a schedule overrun of only 52 days. An appeal has been brought by ANEEL, pending judgment by the Federal Court of the 1st Region. The practical consequence of the ruling was, at the time it exempted ESBR, to expose the distributors with whom it entered into power trading contracts (CCEARs) to the Short-Term Market and to the high value of the Settlement Price of the Differences (Preço de Liquidação das Diferenças - PLD, in Portuguese) in the period, including Copel DIS. This occurred because the rules for the sale of electricity require that all energy consumed should have a corresponding contractual coverage. If the lawsuits are judged unfavorably against Copel, the amount will be classified as Sectorial Financial Asset to be recovered through tariff rates.

Within the scope of that Public Consultation and after receiving the contributions sent by the interested parties, on March 4, 2022, an Opinion was issued by the Federal Prosecutor’s Office with Aneel, which answered questions formulated by the superintendencies of Aneel that evaluate the topic. The regulatory agency has not yet concluded its analysis within the scope of the Public Consultation and, so far, there is no final decision at the administrative level. The Company and its legal advisors evaluated the documents made available in Public Consultation 005/2021 and the Federal Prosecutor’s Opinion, not identifying changes in its previous understanding on the matter, and await analysis by Aneel of their contributions in order to solidify this understanding and protect the Company’s rights.

[2]	The contracts between Petrobras and Compagás were offset by the volume of 55,770,890 m³, disregarding the difference in gas pricing between the contracts (NE 12.1). However, the parties have not reached a consensus to this date, and the amount of R$15,688 remains in dispute. In view of the compensation made by Petrobras and the uncertainty in the reimbursement of the difference in Brazilian reais of the referred Assignment, impairment was recorded for this amount until the end of the transaction.

[1]	The Company manages the credit risk of its assets in accordance with the Management’s policy of investing virtually all of its funds in federal banking institutions. As a result of legal and/or regulatory requirements, in exceptional circumstances the Company may invest funds in prime private banks.
[2]	The risk arises from the possibility that the Company might incur losses resulting from difficulties to receive its billings to customers. This risk is directly related to internal and external factors to Copel. To mitigate this type of risk, the Company manages its accounts receivable, detecting the classes of consumers most likely to default, implementing specific collection policies and suspending the supply and/or recording of energy and the provision of service, as established in contract and regulatory standards.
[3]	There is no risk considering that the balance was settled in 2021.
[4]	Management considers the risk of this credit to be reduced, since the agreements signed guarantee the unconditional right to receive cash at the end of the concession to be paid by the Concession Grantor, corresponding to the costs not recovered through the tariff.
[5]	Management considers the risk of this credit to be reduced, since the agreements signed guarantee the unconditional right to receive cash at the end of the concession to be paid by the Concession Grantor, referring to investments in infrastructure not recovered through the tariff.
[6]	Management considers the risk of such credit to be low, as the contract for the sale of energy by quotas guarantees the receipt of an Annual Generation Revenue - RAG, which includes the annual amortization of this amount during the concession term.
