Significant Accounting Policies
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 associates 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 the calculation of equity in earnings of investees, the investees' financial statements are adjusted to align their policies with the Parent'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 Parent Company's shareholders. Profits, losses and other comprehensive income are also allocated separately from the ones allocated to the Parent 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 associates 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. Accounts receivable from customers without a significant component of financing are 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, except for the asset arising from Certified Emissions Reductions - CERs of Elejor. The Company operates with derivative financial instruments as described in Note 4.15. 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 The Company records changes in sectorial financial assets and liabilities to maintain neutrality between the billed amounts of consumer tariffs, to cover energy costs, charges and other related items, and the forecast for tariff coverage, according to the term amendment to the distribution concessionaires concession agreement, approved by Aneel Order No. 4621/2014. Net sectoral financial assets and liabilities comprise: a) Portion A Cost Variation Compensation Account - CVA, which records the variation between estimated and realized costs of energy purchase, of transmission and sectorial charges; b) financial items that correspond to other rights and obligations included in the tariff. The amounts are updated until the next tariff readjustment/revision and, after approval by Aneel, the new tariff is applied for the current tariff year, providing for collection or return of constituted assets and liabilities, which are then amortized. In the event of termination of the concession for any reason, the residual values of Portion A items and other financial components, not recovered or returned through tariff, must be incorporated in the calculation of the compensation, keeping rights or obligations of the concessionaire with the Granting Authority safeguarded. 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 Granting Authority 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 Granting Authority 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 a 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 Granting Authority 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 (BRR), defined by the Granting Authority, 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 The piped gas distribution concession agreement provides that part of the investments made by the concessionaire is remunerated by the public service users and another part is indemnified by the Granting Authority, the State of Paraná, at the end of the concession. This model provides for the recognition of financial assets, contract assets during the construction period and intangible assets. The amount that will not be amortized within the concession term is presented as Accounts receivable related to the concession and represents the amount to be reimbursed to the Company by the Granting Authority at the end of the contract term. 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 Granting Authority, 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 Granting Authority 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 are 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 Granting Authority, 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 Granting Authority 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 transferred to Accounts receivable related to the concession. 4.5.3 Power transmission concession Represents the balance of public electricity transmission contracts signed with the Granting Authority 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, 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 Granting Authority, 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 (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 are 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 and piped gas Corresponds to acquisition of exploration rights on hydropower potential and piped gas whose onerous concession contract is signed as Use of Public Property - UBP and/or Grant Bonus. This asset is recognized at the present value of future cash disbursements during the Concession Agreement term. At the date of start of commercial operation or acquisition of exploration rights on hydropower potential and piped gas, the amount presented is fixed and 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. 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, number 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 receivables portfolio. 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 that had been recorded in prior years, this reversal is recognized in current year's profit or loss. Assets arising from onerous concession and rights of concession and/or authorization to generate electricity, classified as intangible assets, have their impairment tested along with the other assets of that cash-generating unit. The impairment of contract assets in their construction phase is 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 is subject to guarantee structures, via shared apportionment of eventual default losses among the other members of the national interconnected system managed by the National Electric System Operator (ONS) and by the 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, except for costs or expenses for renewing licenses, which are recorded as intangible assets and amortized over the term of the license. 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 result in no significant amounts, resulting in the non-recognition of such margin. The construction margin adopted for the transmission activity for the years 2022, 2021 and 2020 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 losses arising from the mark-to-market of these contracts (difference between contractual and market prices) are recorded as operating income or operating costs in the Statement of income. 4.15.2 Non-Deliverable Forward (NDF) contracts In addition, the Company operates with Non-Deliverable Forward – NDF

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. Aneel filed an internal appeal against this decision and is awaiting judgment by the Federal Regional Court. The main action awaits its judgment on the merits since February 25, 2019. The contracted energy of the 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 1,2020 Additions/ (Reversals) Write offs Other (a) Balance as of December 31, 2020 Additions/ (Reversals) Write offs Other (a) Balance as of December 31, 2021 Additions/ (Reversals) Write offs (b) Balance as of December 31, 2022 Customers Residential 41,824 65,937 (60,365) - 47,396 117,928 (115,056) - 50,268 112,457 (100,199) 62,526 Industrial 97,954 22,487 (31,575) - 88,866 20,413 (66,848) - 42,431 (12,993) 3,398 32,836 Commercial 70,925 29,092 (31,294) - 68,723 35,628 (46,057) - 58,294 22,510 (48,764) 32,040 Rural 3,389 4,788 (4,240) - 3,937 6,407 (7,384) - 2,960 4,327 (3,460) 3,827 Public Entities 4,890 9 (1,815) - 3,084 184 (2,887) - 381 116 39 536 Public lighting 3 20 (15) - 8 11 (8) - 11 7 - 18 Public service 265 124 (246) - 143 (16) (154) - (27) 2,254 (277) 1,950 Unbilled - captives customers 1,180 409 - - 1,589 885 - - 2,474 (1,487) - 987 Adjustment to present value (1,441) 791 - - (650) (854) - - (1,504) (1,146) - (2,650) 218,989 123,657 (129,550) - 213,096 180,586 (238,394) - 155,288 126,045 (149,263) 132,070 Concessionaires, permission holder and trading companies CCEE (7.2) 119,665 - - - 119,665 - - - 119,665 - - 119,665 Concessionaries and permission holder 20,425 392 (284) - 20,533 1,224 (1,994) - 19,763 (5,353) (4,583) 9,827 140,090 392 (284) - 140,198 1,224 (1,994) - 139,428 (5,353) (4,583) 129,492 Telecommunications 5,149 3,609 (6,260) (2,498) - 3,042 (3,153) 111 - - - - Gas distribution 12,528 238 (509) - 12,257 (2,611) 239 - 9,885 1,064 (568) 10,381 376,756 127,896 (136,603) (2,498) 365,551 182,241 (243,302) 111 304,601 121,756 (154,414) 271,943 (a) Reclassification to Assets classified as held for sale (Note 39).

(b) Effects of the business combination (Note 1.1.1). 12.1.1 Projection for realization of deferred income tax and social contribution: The projection of deferred tax credits realization recorded in noncurrent assets and liabilities is based on the realization period of each item of deferred assets and liabilities and tax losses, also based on projections of future results. These projections were evaluated by the Supervisory Board and approved by the Board of Directors on March 21, 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: - Provision for allocation of PIS and Cofins credits: will be carried out as the amounts are passed on in the tariff review and readjustment processes approved by the regulatory body, if any, or by the reversal of the respective provision; - Provisions for post-employment benefits: realized as the payments are made to the Copel Foundation 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; - 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: The projected realization of the deferred taxes Assets Liabilities 2023 360,933 (232,236) 2024 417,270 (282,299) 2025 486,215 (228,450) 2026 128,402 (227,274) 2027 102,221 (178,671) 2028 to 2030 234,464 (454,087) after 2030 951,439 (951,310) 2,680,944 (2,554,327) 12.1.2 Unrecognized tax credits As of December 31, 2022, Company did not recognize income tax and social contribution credits on income tax and social contribution tax losses in the amount of R$ 197,540 68,826 12.2 Other taxes recoverable and other tax obligations Summary Of Other Recoverable Taxes And Other Taxes 12.31.2022 12.31.2021 Current assets Recoverable ICMS (VAT) 128,288 111,101 Recoverable PIS/Pasep and Cofins taxes (a) 1,110,659 1,396,645 Other recoverable taxes 747 1,118 1,239,694 1,508,864 Noncurrent assets Recoverable ICMS (VAT) 171,374 141,951 Recoverable PIS/Pasep and Cofins taxes (a) 2,421,176 2,967,756 Other recoverable taxes 34,743 33,839 2,627,293 3,143,546 Current liabilities ICMS (VAT) payable(Note 12.2.3) 149,506 290,627 ICMS installment payment (Note 12.2.4) 10,437 - PIS/Pasep and Cofins payable 70,423 42,340 IRRF on interest on capital 11,372 33,592 Special Tax Regularization Program - Pert 57,046 52,168 Other taxes 4,822 22,206 303,606 440,933 Noncurrent liabilities Social security contributions - injunction on judicial deposit 242,248 220,108 ICMS installment payment (Note 12.2.4) 37,883 - Special Tax Regularization Program - Pert 347,029 369,526 Other taxes 6,331 5,176 633,491 594,810 (a) The balance contains amounts referring Pis and Cofins credit on ICMS (Notes 12.2.1 and 12.2.2) 12.2.1 Pis and Cofins credit on ICMS - Copel Distribuição On August 12, 2009, Copel DIS filed for a writ of mandamus No. 5032406-35.2013.404.7000 with the 3 rd nd Regional Court of the 4 th Based on this favorable decision, Copel DIS recognized the tax credit updated in assets, which has been recovered through offsetting with taxes payable since June 2021, from the qualification of the credit originating from Cofins with the Brazilian Federal Revenue Service. The credit originating from PIS was qualified by the Brazilian Federal Revenue Service on August 25, 2022 and is ready to be used through offsetting. On May 13, 2021, the Federal Supreme Court concluded the judgment of the for clarification by the Federal Government in Extraordinary Appeal 574.706/PR, partially granting the following terms: (i) to ICMS excluded from the PIS calculation basis, the understanding that it is the highlighted ICMS ; and (ii) modulate the effects of the judgment whose production will take place after 15 2017, except for judicial and administrative actions filed up to the date of the session in which the judgment was . Therefore, the final decision on this matter did not impact the final and unappealable decision in favor of Copel DIS, maintaining the treatment and amounts recorded. The following table shows the movement of the asset until December 31, 2022: Other taxes recoverable and other tax obligations Balance as of January 1, 2021 5,655,754 Monetary variation 125,483 Offsetting with taxes payable (1,425,972) Balance as of December 31, 2021 4,355,265 Monetary variation 294,952 Offsetting with taxes payable (1,165,601) Balance as of December 31, 2022 3,484,616 Current 1,148,897 Noncurrent 2,335,719 The asset balance will continue to be offset against future federal tax debts. a) Liabilities to be refunded to consumers The Company recorded a liability to be refunded to consumers related to the recovery of tax credits for the last 10 years, counting from the date of the final and unappealable decision, considering the current legislation, the statute of limitations period defined in the civil code and the jurisprudence of the courts. On February 09, 2021, Aneel opened Public Consultation No. 05/2021 aimed at discussing how to return tax credits to consumers, proposing that the amounts to be returned for each tariff cycle (credits with the Brazilian Federal Revenue Office, added to any judicial deposits already received by the concessionaire/permissionaire) are deducted from the electricity bill, through apportionment by the set of consumers. Additionally, Aneel Order No. 361/2021 established that in exceptional situations, in which there is a possibility of a significant tariff increase, part of the PIS and Cofins credits may be used in advance of the conclusion of the public consultation, limited to 20% of the total involved in lawsuits filed by distributors. In the tariff adjustment of June 24, 2022, the total of R$1,593,100 was considered as a financial item, so this balance was transferred to the sectorial financial liabilities account, as shown in the following table: Liabilities to be refunded to consumers Balance as of January 1, 2021 3,927,824 Monetary variation 100,971 (-) Transfer to sectorial financial liabilities (Note 8) (702,000) Balance as of December 31, 2021 3,326,795 Monetary variation 261,463 (-) Transfer to sectorial financial liabilities (Note 8) (1,593,100) Balance as of December 31, 2022 1,995,158 Current 550,527 Noncurrent 1,444,631 The balance of the liability will be refunded to the consumer as the tax credits in the asset are offset. b) Provision for allocation of PIS and Cofins credits On June 27, 2022, Federal Law No. 14,385 was enacted, which defines the allocation of mandatory tax amounts collected in excess by the providers of the public electricity distribution service, due to the recognition by the judiciary that ICMS should be excluded from the PIS and Cofins calculation basis. As detailed earlier in this note, Copel DIS has recognized the right to exclude the full amount of ICMS from the PIS and Cofins calculation basis and has already transferred part of these amounts to consumers, through reductions in the tariff adjustments approved by Aneel. In this context, despite the lack of regulation of this Law, based on the review of the risk assessment carried out by Management, Copel DIS decided to recognize an additional provision, with no immediate cash effect, referring to the period between the 11 th th The Management of Copel DIS understands that the refund to consumers is limited to the tax credit amounts of the last 10 years from the date of the final and unappealable decision and, therefore, is evaluating the appropriate measures to be taken, including legal measures, considering the shelter given to unappealable decisions and applicable limitation periods. On December 12, 2022, the Brazilian Association of Electric Energy Distributors - Abradee filed a Direct Action of Unconstitutionality - ADI with the Federal Supreme Court - STF, questioning Law No. 14,385/2022, which has not yet been judged. The Company awaits the unfolding of the ADI. The table below shows the changes in the provision until December 31, 2022: Provision for allocation of PIS and Cofins credits Balance as of January 1, 2022 - Provision for allocation of PIS and Cofins credits 810,563 Monetary variation 1,011,370 Balance as of June 30, 2022 1,821,933 Monetary variation 29,324 Balance as of December 31, 2022 1,851,257 Any allocation of this provision will occur only after the asset's tax credits are offset. 12.2.2 PIS and Cofins credit on ICMS - Compagas Balance arising from the final and unappealable decision of the lawsuit in which Compagas discussed the exclusion of ICMS from the PIS and Cofins calculation basis. In view of the favorable decision, Compagas recorded assets of R$ 107,453 28,505 75,192 12.2.3 ICMS on electricity operations Supplementary Law No. 194/2022 was published on June 23, 2022, prohibiting that ICMS rates be set on electricity transactions at a level higher than on general transactions, considering the essentiality of related goods and services. Furthermore, it set forth that ICMS is not levied on transmission and distribution services and sector charges related to electric energy transactions. In compliance with the law, and after issue of state tax authorities’ opinions, the Company implemented the necessary changes in September 2022 to comply with the legislation. However, on February 9, 2023, the Brazilian Supreme Court - STF granted States, in a preliminary decision, in the records of Direct Action of Unconstitutionality - ADI 7195, suspension of the article that excluded such items from the taxed portion of the electricity bill. Considering this decision, the Company resumed ICMS taxation on said services and sector charges. On March 3, 2023, the preliminary injunction was approved by the Plenary of the STF. 12.2.4 Incentive installment payment program for ICMS tax credits in the State of Paraná On September 27, 2022, the Company adhered to the installment payment program for previously recognized ICMS, established by the State of Paraná through State Law No. 20946/2021, regulated by State Decree No. 10766/2022, wherein R$92,249 debts were entered in its report of tax position, updated until September 2022 with fine, interest and monetary restatement. By adhering to said program, the Company reduced R$41,696 in charges, with a consolidated balance of R$50,553 at the adhesion date, to be paid in 60 monthly installments until September 2027, according to the mentioned program regulation. The Company has been paying the monthly installments on a regular basis, restated by the Selic rate. 12.3 Reconciliation of provision for income tax (IRPJ) and social contribution (CSLL) The income tax and social contribution credits to be recovered presented in the balance sheet of December 31, 2022, in the amount of R$482,887, refer mainly to the calculation of negative balances that will be offset against federal taxes payable. The table below demonstrates the reconciliation of IRPJ and CSLL recorded in income for the year: Summary Of Reconciliation Of Provision For Income Tax And Social Contribution 12.31.2022 12.31.2021 12.31.2020 Income before IRPJ and CSLL 950,199 5,118,677 5,119,537 (-) Equity in income (478,576) (366,315) (193,547) Income after IRPJ and CSLL 471,623 4,752,362 4,925,990 IRPJ and CSLL (34%) (160,352) (1,615,803) (1,674,837) Tax effects on: Interest on equity (JSCP) 335,697 226,928 276,808 Dividends 250 437 243 Non deductible expenses (26,221) (25,336) (17,133) Tax incentives 13,767 43,720 28,572 Unrecognized tax loss and negative basis of CSLL (128,661) (29,002) (39,421) Setting up and/or offset of income tax and social contribution losses of prior years - 85,723 - Difference between tax bases of deemed profit and taxable profit 35,677 49,638 121,242 Effect of non taxable monetary variation (Selic) on undue tax payments 100,282 - - Others 28,683 4,063 19,161 Current IRPJ and CSLL (429,267) (469,226) (1,260,469) Deferred IRPJ and CSLL 628,389 (790,406) (24,896) Effective rate - % -42.2% 26.5% 26.1%

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) and CAPM (Capital Asset Pricing Model) methodologies, by font type, 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. Several 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.

(in 2021, 5.77% p.a.), which derives from the WACC methodology for the electricity generation segment. The revision of the expected revenue from the sale of energy, which offset increases in operating costs and regulatory charges, and the variation in the book value, enabled the partial reversal of the impairment. 16.4.2 UEG Araucária In December 2022, the value in use calculation considered the Company’s assumptions and budgets, review of the expected dispatch, update of the Variable Unit Cost - CVU and the after-tax discount rate of 7.00% p.a. (in 2021, 7.69% p.a.), which derives from the WACC methodology for the electricity generation segment, plus the additional risk associated with revenue variation. Due to the review of the assumptions, mainly the reduction in the expectation of dispatch from the plant in relation to December 31, 2021, when an increase in demand from the plant was expected because of unfavorable hydrological conditions, impairment was recognized in 2022, considering the significant change in the hydrological scenario of the country. 16.4.3 TPP Figueira In December 2022, the value in use calculation considered the Company's assumptions and budgets, the after-tax discount rate of 6.23 5.77 16.4.4 Other plants in the State of Paraná In December 2022, value in use calculation of generation assets in the State of Paraná considered: i) Company assumptions and budgets; ii) after-tax discount rate of 5.71 5.77 16.4.5 Cash generating units that do not show reversal or provision for impairment The plants that did not suffer impairment have a recoverable value greater than the book value of the property, plant and equipment assets.

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 and the entry into commercial operation of three generating units took place in 2021. The generating center (Stream Diver) has been cleared for start of test operation as of March 28, 2023. 16.5.2 Jandaíra Wind Complex With an estimated investment of R$ 411,610 With all the necessary licenses, the civil works started in January 2021. The complex, with 26 generating units divided into 4 wind farms, began the commercial operation of the entire wind complex during the year 2022. 16.6 Depreciation rates Schedule of average depreciation rates Depreciation rates (%) 12.31.2022 12.31.2021 12.31.2020 Average generation segment rates (Note 16.6.1) General equipment 6.25 6.25 6.26 Machinery and equipment 3.68 3.68 3.39 Generations 3.42 3.42 3.73 Reservoirs, dams and ducts 2.67 2.56 2.68 Hydraulic turbines 2.89 2.90 2.93 Gas and steam turbines 4.00 4.00 4.00 Gas processing 3.00 3.00 3.00 Wind power plant unit 4.94 4.98 4.94 Buildings 3.07 3.15 3.15 Average rates for central government assets Buildings 3.33 3.33 3.35 Machinery and office equipment 6.25 6.27 6.25 Furniture and fixtures 6.25 6.30 6.25 Vehicles 14.29 14.29 14.29 16.6.1 Assets with depreciation rates limited to the concession term The assets of the original project of the Mauá, Colíder, Baixo Iguaçu, Cavernoso II plants and SHP Bela Vista, 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. In the same way, wind generation assets, whose electric energy produced is intended for sale in the Independent Electric Energy Production modality, as established in articles 12, 15 and 16 of Law No. 9,074/1995, are also depreciated at the highest rate between the one determined by the useful life of the assets or the rate calculated based on the authorization period.

The non-compliance with the contracted conditions may imply the need to request consent from the debenture holders or the declaration of early maturity of the debts. As of December 31, 2022, all ratios and covenants have been fully met, except for the subsidiaries Ventos de Santo Uriel and Nova Asa Branca III, which have a debt of R$72,588 on December 31, 2022, and that did not meet the ICSD of 1.3. However, the Company preventively requested and received, on December 30, 2022, according to letter from BNDES AE/DEENE2 No. 061/2022, the commitment of the development banking institution not to declare the early maturity of the debenture deeds, based on the performance of this index in fiscal year 2022. Additionally, the subsidiary Cutia Empreendimentos Eólicos S.A. calculated ICSD of 1.15 and, therefore, needed to supplement the Reserve Account with at least R$5,736. The deposit was made on March 13, 2023, before the contractually defined deadline. The Company expects that all financial indicators, measured annually, will be met in 2023. The financial covenants contained in the debenture agreements are presented as follows: Schedule of financial covenants Company Contractual Instrument Annual financial ratio Limit Copel GeT 4 th Consolidated net debt / Consolidated ebitda ≤ 3.5 5 th 6 th 7 th Copel DIS 4th issue of Debentures 5 th 6 th 7 th Nova Asa Branca I Debt service coverage ratio ≥ 1.3 Nova Asa Branca II Nova Asa Branca III 2 nd Nova Eurus IV Ventos de Santo Uriel Cutia 1 st Debt service coverage ratio (a) ≥ 1.2 (a) financial ratio calculated based on the amounts of the consolidated financial statements of Cutia Empreendimentos Eólicos S.A. The contract establishes that, should the index be in the range between 1.10 and 1.20, the value of the funds invested in the Reserve Account must be complemented so that the total reaches the index of 1.20, within 2 days of the release of the financial statements.

Post-employment Benefits	22. Post-employment Benefits The Company sponsors private retirement and pension plans (Unified Plan and Plan III) and Healthcare Plan for medical and dental care ("ProSaúde II" and "ProSaúde III" Plans) for their active employees and their legal dependents. The lifetime sponsorship of the Healthcare Plan for retirees, pensioners and legal dependents is only applied to "Prosaúde II" plan participants. Fundação Copel de Previdência e Assistência is the entity that manages these plans. 22.1 Pension plan The Unified Plan is a Defined Benefit plan - BD in which the income is predetermined, according to each individual's salary. This plan is closed for new participants since 1998. The Plan III, the only plan available for new participants, is a Variable Contribution - CV plan in the contributory phase and, after retirement, it becomes a Defined Benefit - BD plan. 22.2 Healthcare Plan The Company allocates resources for the coverage of healthcare expenses incurred by their employees and their dependents, within rules, limits and conditions set in "ProSaúde II" and "ProSaúde III" Plans' regulations. Coverage includes periodic medical exams in both plans and is extended to all retirees and pensioners for life only in the "ProSaúde II" plan. 22.3 Statement of financial position and statement of income Amounts recognized in liabilities, under Post-employment benefits, are summarized below: Schedule of liabilities under post-employment benefi 12.31.2022 12.31.2021 Pension plans 949 965 Healthcare plans 1,069,088 1,294,209 1,070,037 1,295,174 Current 73,814 68,836 Noncurrent 996,223 1,226,338 Amounts recognized in the statement of income are shown below: Schedule of post-employment benefits recognized in the statement of income 12.31.2022 12.31.2021 12.31.2020 Employees Pension plans 55,607 59,052 57,977 Healthcare plan - post employment 140,293 116,504 94,349 Healthcare plan - active employees 68,897 71,795 75,192 264,797 247,351 227,518 Management Pension plans 1,236 1,300 977 Healthcare plan 148 122 139 1,384 1,422 1,116 266,181 248,773 228,634 22.4 Changes in post-employment benefits Schedule of changes in post-employment benefits Balance as of January 1, 2021 1,493,614 Appropriation of actuarial calculation 116,504 Appropriation of pension and healthcare contributions 130,308 Adjustment related to actuarial (gains) losses (246,626) Amortizations (198,626) Balance as of December 31, 2021 1,295,174 Appropriation of actuarial calculation 140,293 Appropriation of pension and healthcare contributions 127,878 Adjustment related to actuarial (gains) losses (a) (291,742) Amortizations (201,566) Balance as of December 31, 2022 1,070,037 (a) Adjustments arising from the transfer of liabilities from Copel Serviços to Copel and other subsidiaries. 22.5 Actuarial valuation in accordance with IAS 19 22.5.1 Actuarial assumptions The actuarial assumptions used to determine the amounts of liabilities and costs are shown below: Schedule of actuarial assumptions 2022 2021 Real Nominal Real Nominal Economic Inflation p.y. - 5.10 - 5.50 Expected rate of discount/return p.y.

Provisions For Legal Claims And Contingent Liabilities
Provisions for Legal Claims and Contingent Liabilities	28. 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. On February 8, 2023, when analyzing and judging Topics 881 and 885 of general repercussion (generally binding decision), the STF understood that a final and unappealable decisions (the so-called “res judicata”) on taxes paid on ongoing basis loses its effects if the STF decides otherwise on a constitutionality-related action or an appeal for which it hands down a generally binding decision, since according to the legislation and case law, a decision, even if res judicata, should only produce effects whilst the factual and legal framework which justified it lasts. The Company has no lawsuits that meet the requirements defined by the STF. Therefore, there are no impacts on its financial statements. 28.1 Change in provision for legal claims Schedule of changes in provisions for litigation Income Provision Construction Balances as of Balances as of for litigations cost Additions Transfer/ December 31, January 1, 2022 Additions Reversals Additions (Rev.) to assets Settlements Others 2022 Tax Cofins 110,059 15,109 (1,604) - - - - 123,564 Others 71,056 23,705 (820) - - (9,764) (5,991) 78,186 181,115 38,814 (2,424) - - (9,764) (5,991) 201,750 Labors 569,756 108,902 (2,778) - - (139,416) - 536,464 Employee benefits 37,148 13,270 (19,672) - - (620) - 30,126 Civil Civil and administrative claims 433,437 592,796 (3,925) - - (67,055) 2,858 958,111 Easements 138,069 3,594 (90) (722) 627 (2,754) - 138,724 Expropriations and property 125,028 2,195 (8,113) 4,305 36,924 (5,427) - 154,912 Customers 3,755 2,113 (630) - - (1,488) - 3,750 Environmental 5,902 497 (1,130) - - - - 5,269 706,191 601,195 (13,888) 3,583 37,551 (76,724) 2,858 1,260,766 Regulatory 103,155 5,137 (84,111) - - (15,688) - 8,493 1,597,365 767,318 (122,873) 3,583 37,551 (242,212) (3,133) 2,037,599 Income Provision Construction Transfer/ Balances as of Balances as of for litigations cost Additions Others December 31, January 1, 2021 Additions Reversals Additions/(Rev.) 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 39). 28.2 Details of provisions for legal claims and contingent liabilities The following table shows the details of the provisions for legal claims recorded and, in addition, the amounts of contingent liabilities, which are present obligations arising from past events, but without provisions recognized because it is not probable an outflow of resources that incorporate economic benefits to settle the obligation.

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.

Operating Segments
Operating Segments	33. Operating Segments Operating segments are business activities that generate revenues and incur expenses, whose operating results are regularly reviewed by the executive boards of the Company and by key strategic decision-makers responsible for allocating funds and assessing performance. 33.1 Products and services from which the reportable segments have their revenues generated The Company operates in reportable segments identified by Management, through the chief officers of each business area, taking into consideration the regulatory environments, the strategic business units and the different products and services. These segments are managed separately, since each business and each company require different technologies and strategies. Until December 31, 2022, all sales have been to customers within the Brazilian territory, in addition, all noncurrent assets are also located in the national territory. The Company did not identify any customer who individually accounts for more than 10% of their total net revenue until December 31, 2022. The Company evaluates the performance of each segment, based on information derived from the accounting records. The accounting policies of the operating segments are the same as those described in Note 4 of these financial statements. 33.2 Company’s reportable segments Power generation and transmission (GET) (GER) (TRA) Power distribution (DIS) -

Determining fair values a) Equivalent to their respective book values due to their nature and terms of realization. b) Fair value is calculated based on information made c) Financial assets with fair values ​​similar to book values ​​(Note 4.4). d) The fair values of assets and liabilities are equivalent to their book values (Note 4.15). e) 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. f) The cost of the highest value of the last funding carried out by the Company, CDI + spread of 1.22%, is used as g) 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 h) Calculated according to the quotation of the last trade in the secondary market through the average price of the Unit Price - PU on December 31, 2022, obtained from the Brazilian Association of Financial and Capital Market Entities - Anbima. i) The actual pre-tax discount rate of 8.65% p.a. was used, compatible with the rate estimated by the Company for long-term projects. j) Financial assets with fair values ​​similar to book values ​​(Note 4.2). 34.2 Financial risk management The Company's business activities are exposed to the following risks arising from financial instruments: 34.2.1 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. 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.

As a result of legal and/or regulatory requirements, in exceptional circumstances the Company may invest funds in prime private banks. b) Risk of losses resulting from difficulties to receive amounts billed to customers related to internal and external factors. 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) 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 Granting Authority, corresponding to the costs and investments not recovered through the tariff. d) 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. e) 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. In August 2022, Copel filed with Aneel the assessment reports related to the residual values, with a base date of July 2015, for the HPP Governador Parigot de Souza - GPS and HPP Mourão - MOU, which are awaiting inspection and subsequent validation by the regulatory agency. Management's expectation of indemnification for these assets supports recoverability of the balances recorded. f) Risk arising from the possibility of the Company incurring losses due to stock market volatility. This type of risk involves external factors and is being managed through periodic assessments of the variations in the market. 34.2.2 Liquidity risk The liquidity risk of the Company 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 by 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 Focus Report, which provides the average expectations of market analysts for these indicators for the current year and for the next 3 years. From 2027 on, the 2026 indicators are repeated throughout the forecast period.

As disclosed in Notes 20.4 and 21.3, the Company has loans and financing agreements and debentures with covenants that if breached may have their payment accelerated. 34.2.3 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 effect of the exchange rate variation resulting from the power purchase agreement with 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 to measure the impact of the devaluation of the US dollar on its financial liabilities 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. For the baseline scenario, the accounting balances recorded on the date of these financial statements were considered and for the probable scenario, the Company considers the balance updated with the exchange rate variation - prevailing at the end of the period (R$/US$5.25) based on the median market expectation for 2023 according to the Central Bank of Brazil Focus Report. 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, because of extraordinary events that may affect the economic scenario.

The Company has not entered derivative contracts to cover this risk but has been continuously monitoring interest rates and market indexes to observe any need for contracting. Sensitivity analysis of interest rate and monetary variation risk The Company has developed a sensitivity analysis 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. For the baseline scenario, the accounting balances recorded on the date of these financial statements were considered and for the probable scenario, the Company considers the balances updated with the variation of the indicators (CDI/Selic - 12.50%, IPCA - 5.78%, IGP-M - 4.60% and TJLP - 7.05%) estimated as market average projections for 2023 according to the Central Bank of Brazil Focus Report, except 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, because of extraordinary events that may affect the economic scenario.

(14,455,226) (1,363,618) (1,704,522) (2,045,427) (a) Risk assessment still requires ruling by the Concession grantor. 34.2.4 Electricity shortage risk Most of the installed capacity in Brazil currently comes from hydroelectric generation, 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. Between September 2020 and August 2021, the National Interconnected System - SIN presented the worst record of Affluent Natural Energies in the aggregate of its uses. The Brazilian Ministry of Mines and Energy and other sector bodies worked to maximize the thermoelectric dispatch out of the cost merit order, as well as the easing of restrictions on the system's hydroelectric operation. Additionally, considering the strong wind generation in the Northeast, biomass generation in the Southeast and the rainy season with affluent natural energies that raised the reservoirs to comfortable values, it is estimated that the risk of energy shortages in 2023 and 2024 is minimized. The energy supply guarantee criteria are currently established by the National Energy Policy Council - CNPE through Resolution 29/2019. With reason, the responsible bodies keep the energy deficit risk indicators within the safety margin in all subsystems. 34.2.5 Risk of Generation Scaling Factor - GSF impacts The Energy Reallocation Mechanism - MRE is a system of redistribution of electric power The contracts need to have guarantee. 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 hydroelectric projects participating in the MRE. 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 Regulated Contracting Environment - 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 HPP Mauá, HPP Baixo Iguaçu, HPP Colíder and SHP Cavernoso II. For the distribution segment, the effects of the GSF are perceived in the costs associated with quotas of Itaipu, of Angra, of the plants whose concessions were renewed in accordance with Law 12,783/2013 and the plants that renegotiated the hydrological risk in the ACR, in accordance with Law 13,203/2015. This is a financial risk, since there is guarantee of neutrality of expenses with energy purchases through a tariff transfer. It should be noted that, at least conjuncturally, the GSF risks are greatly reduced due to the improvement in the hydrological scenario in 2022 concomitant with the low load growth. 34.2.6 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, with regard to the deadline for requesting the extension of concessions. According to the mentioned law, the concession operator should request extension of concession at least 36 months before the end date of the contract or act of granting for hydroelectric power plants and electric power transmission enterprises, and 24 months before the end date of the contract or act of granting for thermoelectric plants. The Granting Authority 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 2018, Decree No. 9.271/2018 was published, amended by Decrees No. 10.135/2019, No. 10.893/2021 and No. 11.307/2022, 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 12 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. Some of the generation projects of Copel had their concession period extended due to the effects of the GSF renegotiation, which established the compensation through an extension of the concession period of the plants contemplated by Law No. 13,203/2015, resulting in the approval of the extension period of the concession of these plants through of Ratifying Resolutions No. 2,919/2021 and No. 2,932/2021. For HPP Governador Bento Munhoz da Rocha Netto - 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 the subsidiary F.D.A. Geração de Energia Elétrica S.A. with the purpose of divesting the control of this concessionaire and, thus, allow a new concession grant for 30 years, as provided for in Decree No. 9.271/2018. The process of transforming Copel into a “Corporation” is underway, as described in Note 1, which will allow the Company to maintain 100% interest in the plant. 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 TPP Figueira concession, which expired in March 2019, the Company awaits the conclusion of the process, which is in progress at Aneel and MME. The plant went through a modernization process that provided direct benefits such as improved energy efficiency and reduced emissions of pollutants in the atmosphere, compared to the old plant. The plant was released for commercial operation on December 7, 2022, through Order No. 3,502/2022. According to the Law No. 14,052/2020, the Company may express its intention to extend the concession of the HPP Apucaraninha until January 2024, and the HPP Guaricana and HPP Chaminé 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 Granting Authority. Regarding the transmission segment, the only Copel GeT concession to expire in the next ten years is the Concession Contract No. 75/2001, referring to Transmission Line Bateias-Jaguariaíva 230 kV, which will expire on August 17, 2031. Additionally, regarding the extension of transmission concession contracts, on December 29, 2022 Decree No. 11,314 was published, determining that the extension of transmission concessions may be carried out only when the bidding process is unfeasible or results in damage to the public interest and will be carried out without the advance indemnity of the assets linked to the provision of the service, conditioned to the acceptance by the concessionaire in relation to the revenue and other conditions of the amendment to be prepared by Aneel. 34.2.7 Risk on non-renewal of concessions – distributions of electricity The fifth amendment to Copel DIS 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). Failure to comply with the conditions will result in termination of the concession (clause eighteen, subclause one), with due regard for the provisions of the contract, particularly the right to full defense and adversary system. On November 17, 2020, Aneel approved Normative Resolution No. 896, consolidated by Normative Resolution No. 948/2021, which establishes the indicators and procedures for monitoring efficiency in relation to the continuity of supply and the economic-financial management of public electricity distribution service concessions from the year 2021. According to Aneel Technical Note No. 068/2021 and Authorizing Resolution No. 10,231/2021, as of 2022 the quality targets will become the indicators DEC (System Average Interruption Duration Index) and FEC (Customer Average Interruption Duration Index). Indicators and penalties Indicators and penalties Year Indicator Criteria Penalties From 2021 Economic - financial efficiency in the base year Capital Increase (a) Limitation on distribution of dividends and interest on capital Restrictive regime for contracts with related parties 2 consecutive years Concession termination Quality Indicators in the base year Results plan 2 consecutive years Limitation on distribution of dividends and interest on capital 3 consecutive years Concession termination (a) Within 180 days from the end of each fiscal year, in the totality of the insufficiency that occurs to reach the Minimum Economic and Financial Sustainability Parameter.

QRR: Regulatory Reinstatement Share or Regulatory Depreciation Expense. This value will be the one defined in the last Periodic Tariff Review, updated by the variation of the Regulatory Portion B and calculated on a pro rata basis. Recurring EBITDA: Earnings Before Interest (Financial Result), Taxes (Income Taxes), Depreciation and Amortization. The Company monitors concession indicators in order to anticipate actions that ensure efficiency gains and compliance with regulatory requirements and the result is disclosed in the Regulatory Financial Statements. 34.2.8 Risk of non-extension of the gas distribution concession Upon termination of the concession by the end of the contractual term, the assets linked to the gas distribution services will revert to the Granting Authority, the State of Paraná, and the Company will be compensated for the assets related to the concession that have not yet been amortized, evaluated at their book value monetarily restated up to that date. 34.2.9 Risk of overcontracting and undercontracting of electricity Under the current regulatory model, the agreement for purchase of electric power by distributors is regulated by Law 10,484/2014 and Decree 5,163/2004, which determine that the purchase of energy must be in the volume necessary to serve 100% of the distributor market. The difference between the costs remunerated by the tariff and those actually incurred in the power purchases are fully passed on to captive consumers, as long as the distributor presents a contracting level between 100% and 105% of its market. plus the amounts of involuntary overcontracting recognized by the regulator. Copel DIS estimates that it will end the year with a contracting level of 111.4%, however, it considers that it has sufficient amounts of "involuntary over-contracting" to accommodate the estimated contracting for the year. Thus, there is no risk of penalization for over-contracting. 34.2.10 Gas shortage risk The natural gas market in Paraná, made up of Compagas consumers (non-thermoelectric market) and the Araucária Thermoelectric Power Plant (UEG Araucária), is supplied by contracts with Petrobras that use the transport infrastructure of the Brazil-Bolivia gas pipeline (Gasbol). Compagas signed a contract with Petrobras for the supply of natural gas, effective from 2022 to 2025, which will make it possible to meet the demand that was not contracted for 2022, as well as part of the estimated demand between 2023 and 2025. UEG Araucária, meanwhile, negotiates and signs short-term natural gas contracts as a result of its merchant operation regime. In the current situation of the natural gas sector in Brazil, the Novo Mercado de Gás program, coordinated by the Ministry of Mines and Energy, aims to open the natural gas market to make it dynamic, competitive, integrated with the electrical and industrial sectors. The supply of natural gas is growing and coming from diverse sources, and the great challenge for the sector still focuses on enabling new producers and traders to access infrastructure and the consumer market, currently served mostly by Petrobras. Finally, the new gas law, Law No. 14.134/2021, represents another important step in opening up the Brazilian gas market, in order to make it more competitive and with greater potential for expansion. A possible shortage in the supply of gas could result in losses for Copel due to a reduction in revenue from the natural gas distribution service by Compagas or penalties for non-compliance with the obligations contained in the concession contract. Furthermore, in this scenario, UEG Araucária would probably be kept out of operation. Howev

Central Eólica Aventura IV S.A. Central Eólica SRMN IV S.A. Central Eólica Aventura V S.A. Central Eólica SRMN V S.A. The acquisition is in line with the sustainable growth strategy in renewable energy, expanding the generation matrix diversification in line with the Company’s Strategic Planning and Investment Policy. The transaction includes the Locked box mechanism, in which all cash generated from January 1, 2022 to the closing date will remain in the cash of the acquired Companies. Transaction closing was subject to the satisfaction of certain conditions precedent, which were fully complied with by January 30, 2023, including: obtaining approval from the Brazilian Antitrust Enforcement Agency (CADE), declarations and guarantees, compliance with covenants and obligations, third-party consent, absence of material adverse effect. It is also important to highlight the need for unconditional and unrestricted consent from counterparties to change the control of the acquired Companies, including regarding credit limits for maintenance of financing agreements by the Companies, in accordance with National Monetary Council (CMN) Resolution No. 4995, of March 24, 2022, a condition that was only fulfilled in January 2023. The complexes are located in the state of Rio Grande do Norte, the largest wind energy hub in the country, and have a 260.4 MW installed capacity, with 157.8 MWm of assured energy. The companies have long-term financing (maturities up to 2043) taken out from Banco do Nordeste - BNB, at IPCA rates + 2.19% p.a. (Aventura Complex) and IPCA + 1.98% p.a. (Santa Rosa & Mundo Novo Complex). The seller is developing projects in the vicinity of the Aventura Complex wind farms which, during construction and/or operation, may potentially affect the volume of electricity generated by the wind farms (wake effect) in the future. The seller estimates that these undertakings may start up operations as of January 2027. If the wake effect materializes so that the acquired wind farms generate energy below what was agreed between the parties, the seller will have the obligation to indemnify Copel. Otherwise, if the energy generation is greater, Copel must indemnify the seller. The amount of this indemnification is limited to R$ 4,167 The tables below show the book value and fair value of the net assets acquired, including the effect of deferred taxes (technical goodwill). The fair value was determined based on a preliminary purchase price allocation (PPA) report. Therefore, information is under review and may change. However, no significant changes are expected.

A final outcome depends on the conclusions of legal proceedings. The table below shows the consideration transferred for assets acquired and technical goodwill calculated as a result of the recognized deferred tax liability in the business combination: Total of net assets acquired 403,183 397,933 801,116 Goodwill 204,057 Consideration amount 1,005,173 40.2 Technical Inspection at HPP GBM On March 25, 2023, the scheduled stoppage for inspection of the generating unit 3 of HPP GBM, a plant belonging to FDA, subsidiary of Copel GET, was concluded. An isolated fault was identified in the upper wear ring of the turbine rotor, so that this generating unit will remain unavailable to carryng out a diagnosis on the cause of the incident and the respective actions for its repair, when the return forecast for this generating unit will be updated. Eventual financial impacts related to non-generation or any reduction in the plant's assured energy can only be estimated after the completion of this work.

Significant Accounting Policies
Basis of consolidation	4.1 Basis of consolidation 4.1.1 Calculation of equity in earnings of investees Investments in joint ventures and associates 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 the calculation of equity in earnings of investees, the investees' financial statements are adjusted to align their policies with the Parent'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 Parent Company's shareholders. Profits, losses and other comprehensive income are also allocated separately from the ones allocated to the Parent 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 associates 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.
Financial Instruments	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. Accounts receivable from customers without a significant component of financing are 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, except for the asset arising from Certified Emissions Reductions - CERs of Elejor. The Company operates with derivative financial instruments as described in Note 4.15. 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.
Net sectorial financial assets and liabilities	4.3 Net sectorial financial assets and liabilities The Company records changes in sectorial financial assets and liabilities to maintain neutrality between the billed amounts of consumer tariffs, to cover energy costs, charges and other related items, and the forecast for tariff coverage, according to the term amendment to the distribution concessionaires concession agreement, approved by Aneel Order No. 4621/2014. Net sectoral financial assets and liabilities comprise: a) Portion A Cost Variation Compensation Account - CVA, which records the variation between estimated and realized costs of energy purchase, of transmission and sectorial charges; b) financial items that correspond to other rights and obligations included in the tariff. The amounts are updated until the next tariff readjustment/revision and, after approval by Aneel, the new tariff is applied for the current tariff year, providing for collection or return of constituted assets and liabilities, which are then amortized. In the event of termination of the concession for any reason, the residual values of Portion A items and other financial components, not recovered or returned through tariff, must be incorporated in the calculation of the compensation, keeping rights or obligations of the concessionaire with the Granting Authority safeguarded.
Accounts receivable related to the concession	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 Granting Authority 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 Granting Authority 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 a 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 Granting Authority 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 (BRR), defined by the Granting Authority, 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 The piped gas distribution concession agreement provides that part of the investments made by the concessionaire is remunerated by the public service users and another part is indemnified by the Granting Authority, the State of Paraná, at the end of the concession. This model provides for the recognition of financial assets, contract assets during the construction period and intangible assets. The amount that will not be amortized within the concession term is presented as Accounts receivable related to the concession and represents the amount to be reimbursed to the Company by the Granting Authority at the end of the contract term. 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 Granting Authority, 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 Granting Authority 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 are 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.
Contract assets	4.5 Contract assets Represented by the construction in progress or in service of the infrastructure delegated by the Granting Authority, 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 Granting Authority 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 transferred to Accounts receivable related to the concession. 4.5.3 Power transmission concession Represents the balance of public electricity transmission contracts signed with the Granting Authority 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, 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 Granting Authority, 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.
Accounts payable related to the concession	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 (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.
Inventories (including property, plant and equipment and contract assets)	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.
Property, Plant and Equipment	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 are 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.
Intangible Assets	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 and piped gas Corresponds to acquisition of exploration rights on hydropower potential and piped gas whose onerous concession contract is signed as Use of Public Property - UBP and/or Grant Bonus. This asset is recognized at the present value of future cash disbursements during the Concession Agreement term. At the date of start of commercial operation or acquisition of exploration rights on hydropower potential and piped gas, the amount presented is fixed and 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. 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.
Impairment of assets	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, number 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 receivables portfolio. 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 that had been recorded in prior years, this reversal is recognized in current year's profit or loss. Assets arising from onerous concession and rights of concession and/or authorization to generate electricity, classified as intangible assets, have their impairment tested along with the other assets of that cash-generating unit. The impairment of contract assets in their construction phase is 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 is subject to guarantee structures, via shared apportionment of eventual default losses among the other members of the national interconnected system managed by the National Electric System Operator (ONS) and by the jurisdiction of the sector.
Provisions	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, except for costs or expenses for renewing licenses, which are recorded as intangible assets and amortized over the term of the license.
Revenue recognition	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.
Construction revenues and costs	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 result in no significant amounts, resulting in the non-recognition of such margin. The construction margin adopted for the transmission activity for the years 2022, 2021 and 2020 was 1.65
Power purchase and sale transactions in the Spot Market (Electric Energy Trading Chamber - CCEE	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.
Derivative Financial Instruments	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 losses arising from the mark-to-market of these contracts (difference between contractual and market prices) are recorded as operating income or operating costs in the Statement of income. 4.15.2 Non-Deliverable Forward (NDF) contracts In addition, the Company operates with Non-Deliverable Forward – NDF contracts, which aim exclusively at providing hedge against exchange rate risks associated with cash flows from capital contributions to subsidiaries, when they reflect foreign-currency denominated purchases of projected equipment. They are measured at their fair value, with changes recorded in the statement of income for the year. The fair value is calculated based on the information of each contracted operation and the respective market information on the closing dates of the financial statements.
Taxes	4.16 Taxes 4.16.1 Income Tax and Social Contribution The taxation on profit comprises income tax and social contribution calculated based on the taxable profits (adjusted profit) of each taxable entity at the applicable tax rates according to prevailing legislation, namely, at 15 10 240 9 Income tax and social contribution losses can be offset against future taxable profits, considering the limit of 30 4.16.2 Deferred income tax and social contribution The Company, based on its profitability history and the expectation of generating future taxable profits, based on its internal projections prepared for reasonable periods for its business, sets up a deferred tax asset on temporary differences between the tax bases and on tax losses and negative tax basis. The deferred income tax and social contribution are recognized on temporary differences between the carrying amounts of assets and liabilities in the financial statements and the corresponding tax bases used for tax calculation purposes, to the extent that there will probably be sufficient taxable profits against which the temporary differences can be utilized and the tax losses can be offset. Deferred tax assets and liabilities may be offset if there is a legal right to offset the current tax assets and liabilities and they relate to the same taxing authority. 4.16.3 Other taxes recoverable and other tax obligations Sales and services revenues are subject to value-added tax (ICMS or VAT) and service tax (SS), at the applicable rates, and to the PIS (Social Integration Program) and COFINS (Contribution for Social Security Funding). Credits resulting from non-cumulative PIS and COFINS charges are accounted for as reductions to operating costs in the statement of income. Credits arising from non-cumulative ICMS, PIS and COFINS related to the purchase of assets are presented as reductions to the acquisition cost of these assets. Prepayments or amounts that can be offset are presented in current and non-current assets, according to their expected realization.
Post-employment benefits	4.17 Post-employment benefits The Company sponsors pension plans to supplement retirement and pension plans and the Assistance Plan (medical and dental assistance) for their active employees and their legal dependents. The amounts of these actuarial commitments (contributions, costs, liabilities and/or assets) are evaluated annually by an independent actuary, with the base date that coincides with the end of the year. The economic and financial assumptions for the purposes of the actuarial valuation are discussed with the independent actuary and approved by the Management. The assets of the benefit plans are valued at market value (marked-to-market) by the Company. The value of the net plan liability is recognized at the present value of the actuarial obligation, less the fair value of the plan assets. The adoption of the projected credit unit method adds each year of service as a triggering event for an additional benefit unit, adding up to the calculation of the final obligation. Other actuarial assumptions are used, which take into account biometric and economic tables in addition to historical data from the benefits plans, obtained from the manager of these plans, Fundação Copel de Previdência e Assistência Social. Actuarial gains or losses caused by changes in assumptions and/or actuarial adjustments are recognized in other comprehensive income.
Right to use lease assets and liabilities	4.18 Right to use lease assets and liabilities Upon entering into a lease agreement, the right to use assets is recorded at present value, with a corresponding entry to a lease liability of the same amount, except for agreements that meet the exemption criteria of the accounting standard (short-term leases, low value or those that foresee variable remuneration). After initial measurement, the amortization of the right-of-use asset is recorded in operating result and interest on the lease liability in financial result. To define the interest rate, the Company uses as a basis the nominal rate practiced in the last funding of the Copel group, disregarding subsidized or incentivized funding.

As a result of legal and/or regulatory requirements, in exceptional circumstances the Company may invest funds in prime private banks. b) Risk of losses resulting from difficulties to receive amounts billed to customers related to internal and external factors. 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) 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 Granting Authority, corresponding to the costs and investments not recovered through the tariff. d) 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. e) 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. In August 2022, Copel filed with Aneel the assessment reports related to the residual values, with a base date of July 2015, for the HPP Governador Parigot de Souza - GPS and HPP Mourão - MOU, which are awaiting inspection and subsequent validation by the regulatory agency. Management's expectation of indemnification for these assets supports recoverability of the balances recorded. f) Risk arising from the possibility of the Company incurring losses due to stock market volatility. This type of risk involves external factors and is being managed through periodic assessments of the variations in the market.

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.
