Earnings Release 4Q17

1. Main Events in the Period

COPEL reported an EBITDA of R$521.8 million in 4Q17, a 317.6% increase over the R$124.9 million verified in 4Q16. This result was impacted by the R$25.7 million related to the reversal of estimated losses with generation assets impairment, against a provision for impairment of R$567.1 million in 4Q16, and by the record of R$270.5 million in provisions for lawsuits referring to civil, administrative, labor and post-employment benefit matters.

Copel's adjusted EBITDA in 4Q17 was of R$665.8 million, a 5.1% growth when compared to the adjusted EBITDA in 4Q16 (R$633.3 million), mainly reflecting (a) a 4.8% growth in Copel Distribuição's grid market, (b) a 5.85% of average adjustment applied to Copel Distribuição’s tariffs as of June 24, 2017, (c) RAP adjustment and the start-up of new transmission assets throughout 2017, and (d) a 5.1% decrease in PMSO (Personnel and management, pension and health plans, materials, third party services, provisions and reversals and others), except for provisions and reversals, partially offset by the 42.4% higher cost of electricity purchase, mainly due to the GSF of the period. More details initem 2.

Resubmission of 2016 Comparable Balances

As already disclosed in Note No. 3.2 to the our Interim Financial Information as of September 30, 2017 (“FI 3Q17”), during the preparation of our FI 3Q17, the Company's Management identified an investment by its indirect subsidiary UEG Araucária Ltda. in a Multimarket Investment Fund, which holds shares of other investment funds that in turn invest in a private company, whose main asset is a real estate development.

In light of such finding and in compliance with the best governance practices, the Company's Management relied on independent experts that, together with the Management, conducted an internal investigation into the accounting classification and value of such investment, other impacts and the circumstances of the investment. The valuation has already been concluded, but the investigations are still going on.

After the valuation was concluded and during the investigations, we found that (i) the investment occurred strictly in the UEG Araucária, (ii) this investment violated Copel’s investment policy, which authorizes investments in wholly-owned investment funds only to the extent such funds invest exclusively in bonds issued by the Brazilian federal government or by financial institutions controlled by the Brazilian federal government, (iii) the need to establish a provision for the devaluation of such investment in 2016, due to (a) its specific characteristics, such as (b) that if the correct nature of that investment had been identified during that year, additional analyzes would have been carried out, which would make it possible to conclude that there were signs of a devaluation. As recognized in the 2016 FS previously disclosed, as of December 31, 2016, this investment amounted to R$165.7 million and was recognized under “Bonds and Securities”, as a current asset. This accounting classification was based on the information delivered at that time by the management of UEGAraucária to the Company’s Management, pursuant to which that investment was made in a wholly-owned fund, that was composed of shares issued by other investment funds and government bonds, with immediate liquidity and that were available for sale.

* Amountssubject to rounding.

Earnings Release 4Q17

Based on our conclusions about the investments’ accounting classification and value and based on the information available until the preparation of the 2017 FS, we recognized a provision for the impairment of such investment amounting to R$ 136.9 million as of December 31, 2016. This provision was recorded under “Bonds and Securities” with a corresponding increase in “Financial expenses”. The remaining amount of such investment in 2016, which corresponded to R$28.8 million, was reclassified as a non-current asset in light of the expected term for realizing it.

In light of the above, the opinion of our independent auditors on our individual and consolidated financial statements for the fiscal year ended December 31, 2017 was issued with a qualification with respect to the information related to the fiscal year 2016 and presented for comparative purposes, which was amended and restated to reflect the adjustments discussed above. This qualification was inserted in the auditors’ opinion due to the fact that our internal investigation has not been concluded and the auditors are not able to issue a conclusive and sufficient opinion about whether the impairment provision should be recognized in the financial statements for the fiscal year ended December 31, 2016 (included in the financial statements for the fiscal year ended December 31, 2017 for comparison purposes) or whether this provision should be recognized in earlier fiscal years.

In addition to the above, Copel Distribuição recognized adjustments to the impact of tax litigation in earlier fiscal years. As a result of such adjustments, we recognized an increase of R$ 32.0 million in “Financial expenses” as of December 31, 2016 and a corresponding increase in the provision for litigation under our non-current liabilities, as well as an increase under “Deferred income tax and social contribution” in our Income Statement, amounting to R$ 10.9 million, and the corresponding increase in “Deferred Taxes” in our non-current assets.

As a result of the above mentioned adjustments discussed above, the financial statements for the fiscal year ended December 31, 2016, required for comparison purposes, were amended and restated in the financial statements for the fiscal year of 2017. Please refer to our Standard Financial Statements (Demonstrações Financeiras Padronizadas – DFP) for detailed information (Note No. 4.1).

The following charts reflect the impact of the above mentioned adjustments discussed above in our Balance Sheet and our Income Statement for 2016.

The Company informs that the annual report on Form 20-F to the U.S. Securities and Exchange Commission - SEC, for the year ended December 31, 2017 is in the process of being prepared and will include the restatement of the financial statements for 2016. As a result, the financial statements as of and for the year ended December 31, 2016 and the related report of the Company’s independent registered accounting firm included in the Company’s annual report on Form 20-F for the year ended December 31, 2016 should no longer be relied on.

Reversal of Provision for Estimated Losses with Impairment

In 4Q17, the amount of R$128.2 million was related to the reversal of provision for estimated losses with impairment of credit arising from the gas purchase agreement signed by the compagas with Petrobras, wich contains a clause for the future compensation of balances concerning the purchase of contracted and guaranteed volumes, higher than those effectively extracted and used. Pursuant to the contractual provisions and consumption outlook, resulting from the review of the projects and scenarios for the years ahead, Compagas estimates to fully compensate the amounts paid up to 2024. In addition, if the concession has an early termination due to any reason, the agreement with Petrobras provides for the right to dispose this asset.

* Amountssubject to rounding.

Earnings Release 4Q17

This reversal was partially offset by the provision for impairment related to HPP Colíder (R$44.2 million), TPP Figueira (R$33.8 million), the Cutia and Bento Miguel Wind Complex (R$14.6 million), and to other hydraulic generation assets in the State of Paraná (R$9.9 million). These provisions result from the review of (i) the discount rate, (ii) the assumptions related to the electric energy available for sale in the long term, (iii) delays in the implementation of the construction work and/or modernization, and (iv) an increase in capex to conclude the project.

As a result, the Company had a net balance of R$25.7 million in reversal for impairment in 4Q17.

Provisions for Lawsuits

The Company recorded R$270.5 million in provisions for lawsuits in 4Q17, of which R$181.7 million refers to civil and administrative matters, R$85.6 million to labor and employee benefits matters, and R$3.2 million to tax, regulatory, environmental matters and way easements. Of the balance presented, R$204.7 million are considered non-recurring and are related to matters (i) to arbitrations protected by secrecy and confidentiality, at the probationary stage, without a ruling rendered, (ii) the lawsuit for indemnification on alleged damages due to the implementation of hydroelectric project, and (iii) labor matters.

Copel Distribuição Performance

Copel Distribuição reported an EBITDA of R$110.9 million in 4Q17, a 13.4% increase over the R$97.8 million verified in 4Q16, mainly reflecting the average adjustment of 5.85% on the tariffs as of June 24, 2017, the 4.8% growth in the grid market of the distributor and the 6.5% decrease in manageable costs, partially offset by the higher balances of provisions related mainly to labor and employment benefits matters.

In 2017, EBITDA reached R$573.1 million, 5 times higher than the R$116.6 million reported in 2016, particularly reflecting the 3.4% growth in the grid market of the distributor, the average adjustment of 5.85% on the tariffs as of June 24, 2017 and the 2.6% decrease in PMSO (Personnel and management, pension and health plans, materials, third party services, provisions and reversals and others).

Comparing the reported EBITDA with the regulatory EBITDA (R$1.0 billion), Copel Dis’s performance was 42.8% below the regulatory, reflecting the performance of manageable costs above the tariff coverage, which were impacted by the record of estimated loss for doubtful accounts (PECLD) above of amount of R$35.4 million above the tariff coverage and R$168.6 million in other provisions for disputes.

Earnings Release 4Q17

It should be noted that, in 2017, the personnel costs increased by 0.9% year-over-year (vs. the 2.94% inflation of the last 12 months), mainly reflecting the wage policy adopted as of October 2016, partially offset by the reduction of 276 employees in the workforce during 2017 and the revision of the assumptions that subsidize the actuarial calculation.

The Company has carried out efforts to reduce the difference between the tariff coverage and the effective PMSO. In 2017, the PMSO was 2.6% lower vs 2016, while the tariff coverage increased 7.8%, according to the table below.

Shareholding in Sanepar

In December 2017, the Company participated as a seller of the public offering for the secondary distribution of share deposit certificates ("Units"), each representing one common share and four preferred shares issued by Companhia de Saneamento do Paraná - SANEPAR, in accordance with the documents of the respective offer.

Copel's participation in the transaction included the sale of 8,859,914 Units, which represents all of its Units issued by Sanepar, of which 7,268,653 Units were held by Copel Holding and 1,591,261 Units held by Copel Comercialização, at the price of R$55,20/Unit.

The settlement of the transaction occurred on December 18, 2017 and resulted in the entry of R$484.6 million into the Company's cash.

On December 2016, Copel started to classify its investment in Sanepar as a financial asset available for sale. The initial recognition of the asset was based on the fair value and its variation recorded directly in the equity, net of taxes. With the total sale of this investment, in December 2017, the accumulated earnings in the equity were reclassified for the fiscal year’s income, totaling R$28.7 million.

General Meeting of Debenture Holders

2. Financial Performance

The following analyzes refer to the fourth quarter of 2017 and to the accumulated of year compared to the same period of 2016.

2.1 Operating Revenues

In the fourth quarter of 2017, net operating revenue totaled R$3,910.7 million, an increase of 18.6%, compared to the R$3,297.1 million registered in the 4Q16, a result of (a) a 29.2% growth in the “electricity sales to distributors”, mainly due of dispatch of 195.2 GWh of Araucaria TPP and the sale of 920 GWh by Copel Comercialização in bilateral contracts; (b) a 14.4% increase in "electricity sales to final customers" revenue, as a result of Copel Distribuição's tariff adjustment effective as of June 24, 2017, which adjusted the energy tariff (TE) by 10,28%, and the sale of 258 GWh to free customers of Copel Comercialiazação; (c) of the positive result of R$381.1 million in sectorial financial assets and liabilities (compared to R$110.5 million in 4Q16), due to the lower hydrological risk (GSF), from 69.3% in 4Q17 to 88.3% in 4Q16, and the higher average PLD in the period (R$398.09/MWh in 4Q17 compared to R$162.82/MWh in 4Q16);

The following variations are also worth mentioning:

(i) the 3.3% growth in the “use of the main distribution and transmition grid" line, due to (a) the 4.8% growth in the 4Q17 grid market, (b) Copel’s tariff adjustment, which adjusted the TUSD by 0.85% as of June 24, 2017, and (c) the adjustment applied to the RAP as of July 2017, partially offset by the removal of the balance of revenue from group companies (Copel GeT and Copel Distribuição) referring to the portion of APR related to RBSE, which was recognized in GeT’s revenue during 2016 and at the beginning of 2017;

(ii) the 10.3% increase in “revenues from telecommunications”, due to the expansion of services to new customers;

(iii) the 34.4% decrease in “other operating revenues”, mainly due to lower revenues from fines and with provision of technical services to third parties;

(iv) the 7.9% drop in “distribution of piped gas”, due to the reduction in the natural gas consumption, partially offset by the TPP Araucária dispatch.

In the 2017, Copel's net operating revenue increased by 7.0%, mainly due to the result of sectorial financial assets and liabilities and the incresase of 18.7% in the revenue of electricity sales to distributors, mainly due to the registration of R$275.1 million in revenue at Copel Comercialização and an increase of 18.1% in telecommunications revenues, due to the expansion of the customer base, partially offset by (a) a drop of 10.5% in eletricity sales to final customers, reflecting the 11.6% reduction in the captive market of Copel Distribuição; (b) a reduction of 9.0% in use of the main distribution and transmission grid, mainly due to the recognition of R$809.6 million related to the recognition of the indemnification of assets related to RBSE in 2016; and (c) a 3.6% reduction in distribution of piped gas, due to the 2.5% drop in natural gas consumption in the period.

Disregarding the effect of the recognition of indemnification of RBSE related assets in 2016 and its adjustment in 2017 (R$183.0 million in 1Q17), the Company would have ended 2017 with a 12.6% growth in net operating revenue.

2.2 Operating Costs and Expenses

In 4Q17, operating costs and expenses increased by 6.5%, totaling R$3,618.1 million. This result was mainly due to the 42.4% increase in costs with "electricity purchased for resale”, as a result of the higher hydrological risk (GSF of 69.3% in 4Q17 vs. 88.3% in 4Q16) and the higher average PLD in the period (R$398.09/MWh in 4Q17 vs. R$162.82/MWh in 4Q16); partially offset by the lower balance of provisions and reversals (R$268.4 million in 4Q17 versus R$603.7 million in 4Q16) due to the net effect of R$25.7 million referring to the reversal of impairment in 4Q17, while in 4Q16 the amount of R$567.1 million was reported for impairment of generation assets. Also on this line, it is noteworthy (a) the 65.1% decrease in provisions related to doubtful accounts - PECLD (R$18.2 million in 4Q17 versus R$52.3 million in 4Q16) and (ii) the 78.1% decrease in provisions related to tax credit losses, offset by the record of R$270.5 million in provisions for civil and administrative matters (R$181.7 million), labor and employee benefits matters (R$85.6 million), regulatory matters, environmental taxes and way easements (R$3.2 million).

Earnings Release 4Q17

Excluding the cost of user fees for water resources and supervision, as well as the effect of classification and disposal of the investment in Sanepar, manageable costs decreased by 4.0% (R$733.0 million in 4T17 and R$763.2 million in 4Q16).

It should be noted that the "personnel and managers" showed 7.5% decrease and mainly reflects lower compensation costs with remuneration, as a result of the salary policy applied as from October 2017, and the lower provision balance for indemnities related to the Incentive Dismissal Plan (PDI). Up to December 31, 2017, there was a reduction of 281 employees in Copel's personnel, of which 248 joined the PDI and left the Company in 2017. The adhesion of these employees to the program represented a cost of R$40.4 million in 2017, with a cost reduction of around R$60.2 million as from 2018. The costs of "pension and healthcare plans" decreased by 7.9% due to the lower amount allocated to the "post-employment plan", motivated by the revision of the assumptions that subsidize the actuarial calculation.

In 2017, operating costs and expenses totaled R$11,894.9 million (6.3% up). This result was mostly impacted by (a) the 31.6% increase in “electricity purchased for resale”, caused by the higher hydrological deficit (18.4% in 2017 and 11.8% in 2016) and the higher PLD (PLD médio de R$ 318,15/MWh em 2017 ante R$ 92,40/MWh em 2016), (b) 191.9% increase in "materials and supplies for power electricity" costs, due to TPP Araucária's dispatch in 4Q17, and (c) 3.0% increase in "personnel and managements", in line with inflation in the period(IPCA of 2.94% in 2017), impacted by the provision of R$51.4 million for compensation for voluntary dismissals and retirement, and for the wage policy adopted from October 2017.

Earnings Release 4Q17

These events were partially offset by (a) a reduction of 52.4% in "provisions and reversals", reflecting the reversal of impairment in the amount of R$122.8 million in 2017, against a provision of R$581.6 million related to impairment in 2016; and (b) a reduction of 17.8% in "charge of the main distribution and transmission grid", mainly due to CCEE's decision to pass on to the market the excess of resources accumulated in the CONER account - given the high of the PLD throughout 2017.

2.4 EBITDA

In 4Q17, earnings before interest, taxes, depreciation and amortization reached R$521.8 million, 317.6% higher than the R$124.9 million reported in 4Q16. While in 2017, EBITDA reached R$2,878.8 million, 4.6% more than in the same period of 2016 (R$2,752.4 million).

* Amountssubject to rounding.

Earnings Release 4Q17

Excluding extraordinary effects, the adjusted EBITDA in 4Q17 would be 5.1% higher year-over-year, mainly due to the order on TPP Araucária and the 4.8% increase in Copel Distribuição’s grid market and the reduction of 5.1% in PMSO, partially offset by the worsen GSF, in line with the high PLD, generating higher costs with electric energy purchase.

The 2017 EBITDA would be 15.1% higher than the R$2,400.6 million in 2016, explained mainly by the significant growth of Copel Distribuição's EBITDA, reflecting the tariff readjustment applied as of June 24, 2017, 3.4% growth in the grid market and control of manageable costs; and by 2.7% and 7.1% growth in Copel GeT's electricity sales to final customers and distributors revenues, partially offset by higher energy purchase costs due to the effect of the GSF.

The following table presents the items considered in the adjusted EBITDA calculation.

2.5 Financial Result

In 4Q17, financial revenues totaled R$164.2 million, a 17.2% decrease over the R$198.5 million recorded in 4Q16, mainly due to judicial deposit update.

The financial expenses totaled R$357.0 million, a 36.8% decrease over 4Q16, mainly due to the restatement of 2016 balances, resulting from the provision for the devaluation of the R$136.9 million investment made by UEG Araucária in Multimarket Investment Fund. See more details in Note 4.1.1 of our Financial Statements.

In addition, the reduction in financial expenses was also affected by the lower exchange variation on the purchase of electric energy from Itaipu and the reduction of debt charges due to the SELIC rate reduction (in 4Q17 the DI average was 7.47% over 13.84% in 4Q16). The higher balance of financing and debentures partially offset the decrease in the financial expenses.

The following table shows these changes and the financial result.

3.Main Account and Changes Balance Sheet

The main accounts and changes in the Balance Sheet in relation to December 2016 are described below. Additional information can be found in the Notes to our Financial Statement.<0}

3.1 Main Accounts

Cash, Cash Equivalents and Bonds and Securities<0}

On December 31, 2017, the cash and cash equivalents, bonds and securities of Copel’s wholly owned subsidiaries and controlled companies totaled R$1,286.1 million, 4.2% lower than the R$1,342.7 million recorded on December 2016. These funds were invested, mostly in Bank Deposit Certificates (CDBs) and repo transactions. These investments are remunerated between 60% and 100% of the variation rate of the Interbank Deposit Certificate (CDI).

<<CRC Transferred to the State of Paraná

Through the fourth addendum signed on January 21, 2005, the Company renegotiated the CRC balance on December 31, 2004 with the State of Paraná at R$1,197.4 million, in 244 monthly installments recalculated by the price amortization system, restated by the IGP-DI inflation index plus annual interest of 6.65%. The first installment was due on January 30, 2005, with subsequent and consecutive maturities until April 2025.

The State of Paraná requested the Company and the Board of Directors approved, on June 16, 2016, subject to the consent of the Department of the Treasury, the Novation of the CRC Adjustment Agreement, which contemplates: (i) from April to December 2016, a total grace period for principal and interest payments; and (ii) from January to December 2017, a grace only the principal amount, but with monthly interest payments. The other clauses would be maintained, including the maintenance of the current correction and interest rates, thus not affecting the overall net present value of said agreement.

The State of Paraná complied with the agreed terms and made the payments of the monthly installments of interest estimated until December 2017. Once the grace period ended, as of January 2018, there are 88 monthly installments, which are being paid strictly under the conditions contracted.

The Company's management and the State of Paraná formalized the Fifth Amendment on October 31, 2017. The current balance of the CRC is R$1,516.4 million.

Other temporary investments

In November 2016, the Shareholders' Agreement, signed between the state of Paraná and Dominó Holdings, was terminated, removing from Dominó Holdings the significant influence over its investment in Sanepar. This occurred due to the conversion of common shares into preferred shares issued by Sanepar and held by DominóHoldings. Given this fact, the investment of Sanepar which ceased to be classified as an associated company and is now considered a financial asset available for sale. Accordingly, its recognition is no longer recorded under the equity method, but rather at fair value. On September 30, 2017, the balance of this account amounted to R$489.3 million, R$470.7 million of which is related to Copel’s investment in Sanepar.

* Amountssubject to rounding.

Earnings Release 4Q17

Copel's participation in the transaction included the sale of 8,859,914 Units, which represents all of its Units issued by Sanepar, of which 7,268,653 Units held by Copel Holding and 1,591,261 Units held by Copel Comercialização, at the price of R$55,20/Unit. As a result, the Company ceased to have an investment in Sanepar, and as of December 31, 2017, the balance of this account totaled R$18.7 million.

Sectorial Financial Assets and Liabilities

As of December 31, 2014, Copel Distribuição has recognized sectorial financial assets and/or liabilities in its financial statements as a result of an amendment to the concession agreement, that guarantees that the residual amounts of items of Portion A and other financial components not recovered or returned via tariffs will be included in, or discounted from, the calculation of the indemnification for non-amortized assets at the expiration of the concession. On December 31, 2017, the Company had a net asset of R$59.7 million. More detail in our Financial Statement (Note 9).

Accounts Receivable Related to the Concession

This line refers to accounts receivable related to the contracts for the concession of electric power generation, transmission, distribution and distribution of natural gas activities. The amounts refer to (a) the concession fee paid as a result of the auction involving the Governador Parigot de Souza Plant – HPP GPS, won by Copel GeT on November 25, 2015 (R$606.5 million), (b) its investments in infrastructure and financial remuneration that have not been or will not be recovered via tariffs and/or APR until the expiration of the concession (R$2,181.6 million), (c) the amounts receivable from energy transmission assets of the Existing System Basic Network – RBSE and connection facilities and other transmission facilities - RPC, as a result of the recognition of the effects of MME Ordinance No. 120 and the approval, by Aneel, of the result of the inspection of the appraisal report of these assets (R$1,418.4 million) and (d) the gas distribution concession agreement - Compagas (R$303.6 million).

Due to the publication of Complementary State Law 205/2017, which brought a new interpretation on the due date of Compagas concession (from July 06, 2024 to January 20, 2019), a transfer of R$160.0 million was made from the intangible to Accounts Receivable Related to the Concession. More details in our Financial Statement (Note 2.1.1).

Earnings Release 4Q17

As of December 31, 2017, the balance of the account totaled R$4,510.1 million. More details in our Financial Statement (NE n ° 10).

Accounts Receivable related to the Concession Indemnification

This account refers to the residual value of the generation assets whose concession expired in 2015 (Rio dos Patos HPP, GPS HPP and Mourão I HPP). On December 31, 2017, the amount registered in this account was R$68.9 million. More details in Notes 11 to our Financial Statement.

Investments, Property, Plant and Equipment and Intangible Assets

"Investments" moved up 9.8% until December 31, 2017, due to equity in the earnings of subsidiaries and capital contributions recorded in the period. “Property, plant and equipment” increased 10.0%, due to the startup of new assets, in accordance with the Company's investment program, net of period depreciation. “Intangible assets” decreased by 0.1% due to the adjustment made as a result of the new interpretation on the maturity of the Compagas concession, partially offset by investments in new assets in the period.

4. Performance of the Main Companies

4.1 Copel Geração e Transmissão

Copel GeT reported a positive EBITDA of R$119.7 million in 4Q17 versus a negative EBITDA of R$100.5 million verified in 4Q16. It should be noted that the result of Copel GeT in 4Q16 was adversely impacted (a) by the negative equity result of R$445.4 million related to (i) the impairment of the Cutia Wind Complex and (ii) R$69.1 million of impairment and R$136.9 million related to the provision for investment devaluation made by UEG Araucária (adjustment made in 2017 with the restatement of the 2016 balances), and (b) R$110.6 million related Copel GeT’s impairment.

In relation to the EBITDA recorded in 4Q17, the amount calculated was mainly impacted by the higher cost of energy purchases (R$147.5 million in 4Q17 versus R$11.8 million in 4Q16), due to the lower GSF (69.3% in 4Q17 compared to 88.3% in 4Q16) and the recording of R$185.1 million in provisions and reversals.

The manageable costs, excluding estimated losses, provisions and reversals, and fees on water use and inspection, decreased by 0.2% and mainly reflect the lower costs with personnel and management, pension and healthcare plans and materials.

The “personnel” line had a 1.5% decrease and mainly reflects the lower balance of the indemnification provision concerning the Incentive Dismissal Plan. Up to December 31, 2017, 53 employees joined the incentive dismissal program and left the Company throughout the year. The adhesion of these employees to the program represented a cost of R$11.3 million in 2017, with a cost reduction perspective of R$15.5 million as of 2018.

Excluding the provisions with indemnities for the Incentive Dismissal Program, the costs with personnel and administrators increased by 0.8% (compared to 2.94% inflation of the last 12 months), reflecting the adjustment applied to salaries as of October 2017 and the organizational restructuring of Copel Renováveis as of September 2017, which resulted in the transfer of activities and of 56 employees to Copel GeT.

4.2 Copel Distribuição

Copel Distribuição reported an EBITDA of R$110.9 million in 4Q17, a 13.4% increase over the R$97.8 million verified in 4Q16, mainly reflecting the average adjustment of 5.85% on the tariffs as of June 24, 2017, the 4.8% growth in the grid market of the distributor partially offset by the higher balances of provisions related mainly to labor and employment benefits matters (R$80.0 million in 4Q17 versus R$8.5 million in 4Q16).

The “result of sector financial assets and liabilities” account totaled R$381.1 million and corresponds the higher costs of electric energy purchased for resale, mainly due to the higher hydrological deficit (30.7% in 4Q17 versus 11.7% in 4Q16) and the average PLD (R$398.09/MWh in 4Q17 and R$162.82/MWh in 4Q16).

The manageable costs, excluding estimated losses, provisions and reversals, decreased by 6.5% and mainly reflect the lower costs with personnel and management, pension and healthcare plans and indemnities.

It should be noted that the costs with personnel and management decreased by 6.5%, mainly as a result of lower costs with compensation due to the salary policy applied as from October 2017, and the lower provision for indemnities is due to the Incentive Dismissal Plan. Up to December 31, 2017, there was a reduction of 276 employees in Copel Distribuição’s staff, of which 175 joined the incentive dismissal program and left the Company throughout 2017. The adhesion of these employees to the program represented a cost of R$23.5 million in 2017, with a cost reduction perspective of R$37.7 million as of 2018.

The net income 4Q17 was of R$85.8 million, 73.1% higher than the R$49.6 million year-over-year, mainly due to, in addition to the factors mentioned above, the lower financial expense related to debt charges.

In 2017, Copel Distribuição recorded an EBITDA of R$573.1 million, 5 times higher than 2016 (EBITDA of R$116.6 million). This performance was mainly affected by (i) the 3.4% increase in 2017 grid market, (ii) the average adjustment of 5.85% on the tariffs as of June 24, 2017, and (iii) the 15.81% reduction in provisions and reversals, mainly due to the lower balance of PECLD (R$83.9 million in 2017 versus R$171.0 million in 2016), partially offset by higher provisions related to lawsuits on benefits to employees.

Manageable costs, excluding estimated losses, provisions and reversals, were in line with 2016, totaling R$1,542.9 million, while personnel and management costs increased 2.2%, below the year’s inflation, mainly reflecting the policy of not replacing job vacancies.

Excluding the non-recurring effects of provisions and reversals and the record of PECLD above the tariff coverage, Copel Distribuição’s EBITDA would be of R$142.7 million in 4Q17, an 3.7% increase over the R$137.6 million in 4Q16. In 2017, EBITDA would be of R$636.5 million, 106.2% higher than in 2016 (R$308.8 million).

4.3 Copel Telecomunicações

Copel Telecom reported an EBITDA of R$23.9 million in 4Q17, a 2.5% decrease when compared to R$24.5 million verified in 4Q16. This result reflects higher costs with third-party services and advertising and marketing, partially offset by 13.6% growth in telecom revenues, due to the expansion of the customer base.

The manageable costs, excluding estimated losses, provisions and reversals, increased by 13.5% in the period, mainly due to the increase in advertising costs (in line with other costs and operating expenses) and to the increase with third-party services, which are required to expand the area of operations, partially offset by the reduction in the “personnel” and “private pension and healthcare plans” line.

⁽²⁾Updated by Resolution nº 2,265, of July 4, 2017, of Aneel.

Copel was designated as the interim operator of the Rio dos Patos plant (1.7 average MW of installed capacity and 1 average MW of assured power) after the final term of the concession, awaiting the MME's decision on ANEEL's recommendation for the extinction of the plant without the reversal of the assets to the granting power. However, its operation was suspended in September 2014 due to flood damage in July of that year.

In view of this scenario, awaiting the confirmation by MME, Copel is carrying out the pertinent analyzes regarding the best use to be made of the assets of this plant, as well as the necessary actions in case of reversion of the assets to Copel.

Colíder Hydroelectric Power Plant

On July 30, 2010, under Aneel New Energy Auction no. 003/2010, Copel GeT was awarded the concession to explore the Colíder HPP for a term of 35 years, commencing January 17, 2011, the signing date of MME - Colíder HPP Concession Agreement no. 001/11.

The project is part of the Brazilian Government’s Growth Acceleration Program - PAC and will consist of a main power house with an installed capacity of 300 MW, sufficient to serve around 1 million inhabitants, based on the estimated energy potential of the Teles Pires River on the border of the municipalities of Nova Canaã do Norte and Itaúba, in northern Mato Grosso.

The BNDES endorsed the qualification of the Colíder HPP for feasibility analysis of financial support and the financing agreement, in the amount of R$1,041.2 million (Note 23). The amounts released up to December 31, 2017 total R$975.1 million.

Due to force majeure events and government acts, such as fire in the construction site, difficulties related to environmental licensing, supplier delays in equipment delivery and services related to electromechanical assembly and construction of the transmission line associated with the plant, the schedule of the project was affected, leading to the postponement of the beginning of commercial generation: the startup of the first generation unit is scheduled for May 2018 and the third and last generation unit is expected to begin operations in November 2018. As a result of these events, this project shows an asset impairment balance of R$683.0 million as of December 31, 2017 (R$595.5 million as of December 31, 2016).

The energy from the Colíder HPP was sold at an Aneel auction at a final tariff of R$103.40/MWh, as of July 1, 2010, restated by the IPCA inflation index to R$163.41 on December 31, 2017. A total of 125 average-MW was traded, to be supplied beginning January 2015, for 30 years. Copel GeT filed with Aneel a request for exclusion of liability, so that the obligation to supply the energy sold is postponed. The request was not accepted in firstinstance; however, the Company exercised its right to appeal and filed a motion for rehearing, which was denied on March 14, 2017. As Copel GeT does not agree with the decision, it filed another motion for rehearing, which was denied on a final basis on July 4, 2017. Not agreeing with the decision, Copel GeT again requested the reconsideration, which was definitively denied on July 4, 2017. Copel GeT filed on December 18, 2017 an ordinary action with the Judicial Court requesting the reversal of the agency's decision.

Copel GeT has been honoring energy supply agreements as follows:

• from January 2015 to May 2016: with energy surplus of its other plants that has not been contracted;

• from June 2016 to December 2017: partial reduction in June 2016 through a Bilateral Agreement and reduction of all Energy Commercialization Agreements in the Regulated Environment – CCEARs between July 2016 and December 2017 through a Bilateral Agreement and participation in the Mechanism for Compensation of Surpluses and Deficits – MCSD of New Energy.

The project’s assured energy of 177.9 average-MW, established by Ordinance 258 of the Ministry of Mines and Energy (MME) of December 21, 2016, was increased to 178.1 average-MW, according by Ordinance 213 / SPE of the MME, of July 14 2017.

On December 31, 2017, Colíder HPP expenses totaled R$2,197.6 million.

Baixo Iguaçu Hydroelectric Power Plant

Copel holds a 30% interest in the Baixo Iguaçu Consortium (CEBI). The purpose of the consortium is to build and operate the Baixo Iguaçu Hydroelectric Power Plant, with an installed capacity of 350.2 MW and assured power of 171.3 average-MW located on the Iguaçu river, between the cities of Capanema and Capitão Leônidas Marques, and between HPP Governador José Richa and the Iguaçu National Park, in the State of Paraná. With an estimated total investment of R$2.3 billion, the first unit of the plant is expected to start operating in November 2018. The work on the construction site began in July 2013, with the excavation of the generation circuit, the earthworks of the construction site and the construction of the housing areas.

The beginning of the commercial generation of unit 1 is currently expected for the end of November 2018, and of units 2 and 3 for December 2018 and January 2019, respectively. The original schedule was changed due to the suspension of the Installation License, according to the ruling of the Regional Federal Court of the 4th Region (TRF-RS), which occurred on June 16, 2014, and paralyzed the construction works from July of that year. In March 2015, a ruling authorizing the resumption of the construction works was issued. However, the Chico Mendes Institute for Biodiversity Conservation (ICMBio) enforced additional constraints on the environmental licensing, which prevented the immediate resumption of the construction work. CEBI submitted to the Environmental Institute of Paraná (IAP) all the necessary information to comply with these constraints and, inAugust 2015, the license was issued. After the measures discussed and agreed with the Developer Consortium, on February 1, 2016, the construction work was fully resumed.

Earnings Release 4Q17

In August 2016, Aneel issued the 2nd Amendment to the Concession Agreement, in order to formalize the redefinition of HPP Baixo Iguaçu’s schedule, as well as its final closing date, acknowledging, in favor of CEBI, an exemption of liability for the delay in the implementation of the project for a period corresponding to 756 days, recommending to the MME the extension of the term of the grant and establishing that the CCEE must postpone the beginning of the supply period of the CCEARs for the period of the recognized exemption of liability.

On November 7, 2017, Aneel recognized an additional 46 days of exclusion of liability for the delay in the implementation of the Baixo Iguaçu HPP, barring any penalties and contractual, commercial or regulatory obligations arising from the delay. The project already had 746 days of exclusion of liability; therefore, its concession term will now expire on October 30, 2049 and supply of the Energy Commecialization Agreements shall begin on November 12, 2018.

At the construction site, the works are following the schedule established when the work was resumed. The assembly activities of the powerhouses and the spillway are fully in progress, as are the social and environmental programs.

Compact-Design Distribution Lines

Copel Distribuição has continued to implement compact-design distribution lines in urban areas with a high concentration of trees surrounding the distribution grids. This technology reduces the number of trees cut down or trimmed, and improves the quality of power supply by reducing the number of unplanned outages. In December 2017, the total length of compact-design distribution lines in operation was 9,616 km.

Secondary Isolated Lines

Copel Distribuição has also invested in low-voltage (127/220V) secondary isolated lines, which offer substantial advantages over regular overhead lines, including: improvement in DEC and FEC distribution performance indicators, defense against illegal connections, improved environmental conditions, reduced areas subject to tree trimming, improved safety, reduced voltage drops throughout the grid, and increased transformer useful life, due to the reduction of short-circuits, among other advantages. The total length of installed secondary isolated lines closed December 2017 at 17,384 km.

Copel, in partnership with the companies Brennand, Minas PCH and Silea, is also developing studies in the lower reaches of the Rio Chopim that will lead to the feasibility of another four (4) hydroelectric projects. As for wind power generation, there are studies for the feasibility of new wind farms in the State of Rio Grande do Norte, where Copel already has wind assets. The short-term objective is to register such projects in the EPE to enable participation in the upcoming auctions to be organized by the Federal Government. The technical characteristics may be adjusted until the effective energy commercialization of the projects, since Copel's engineering is conducting optimization studies, in order to make the projects more competitive.

Oil and Gas Exploration and Production (Paraná Gás

Exploração e Produção S.A)

On November 28, 2013, in the 12th round of Bids of the National Petroleum Agency (ANP), the consortium formed by Copel (30%), Bayar Participações (30%), Tucumann Engenharia (10%) and Petra Energia (30%) (the latter acting as operator) won the right to explore, develop and produce oil and natural gas in four blocks in an 11,327 km² area in the midwestern region of the State of Paraná. The consortium’s total investment will come to R$78.1 million in the first phase of exploration, for the term of four years granted by the ANP. Copel and its partners Bayar, Tucumann and Petra signed concession contracts for 2 blocks in May 2014. At the end of 2016, State Law No. 18.947/2016 was sanctioned, suspending por ten years the environmental licensing of any drilling or exploration activity of shale gas by the hydraulic fracturing method, better known as "fracking".

Due to the ruling rendered regarding the Public Civil Action referred to above (in the lower court), issued on June 7, 2017, stating the nullity of the bidding procedure and the respective agreements signed for the areas of the Rio Paraná Basin, and the lack of compliance prospects of the object of ANP’s 12th Round of Bids, the consortium resolved to request to ANP the discharge from its contractual obligations under the 12th Round of Bids without charges to the bidders, with the consequent refund of the signature bonus, reimbursement of the guarantee costs incurred and discharge of the guarantees presented (application filed at ANP on June 6, 2017).
