1. Main Events in the Period

Copel recorded recorring EBITDA of R$707.2 million in 2Q17, an increase of 58.1% over the recurring EBITDA of R$447.3 million in 2Q16, mainly due to the result of the 4th Tariff Review Cycle of Copel Distribuição, the lower balance with provisions and reversals, especially in allowance for doubtful accounts, and the higher average PLD in the period, partially offset by the recognition of R$31.2 million in impairment and R$67.0 million in additional costs with construction related to the transmission lines. More details in theitem 2.

Provisões e Reversões

In 2Q17, the Company recorded R$ 98.5 million in provisions and reversals, (i) R$31.2 million refers to the impairment of assets of the Bento Miguel Wind Complex, (ii) R$29.0 million to net provisions for labor lawsuits, (iii) R$25.7 million to allowance for doubtful accounts (PECLD).

In the same period of 2016, the Company recorded a reversal of R$211.4 million, mainly related to the final and unappealable decision issued in favor of Copel Holding Company with regard to the lawsuit that required the Company to pay Cofins and respective interest and fine due to the termination of the ruling court that had exempted the Company from paying Cofins, and constitutes a provision of R$147.2 million, of which R$60.9 million was related to doubtful accounts.

Reduction in the recoverable value of assets of the generation segment – Impairment

In the second quarter of 2017, a complement was added to the estimate in order to reduce the recoverable value of the wind power assets of the Bento Miguel Wind Complex, whose impact on the result was R$31.2 million. The calculation of the value took into account the assumptions used in the impairment tests carried out in 4Q16, with the most relevant being: updating the discount rate and increasing the projects’ CAPEX.

Restatement of comparative balances

The Company’s management adjusted the consolidated financial statements at June 31, 2017, December 31, 2016 and June 31, 2016 as follows:

Fair value of concession assets

In order to better present its operational and financial performance, on December 31, 2016, the Company reviewed its accounting practices and concluded that the adjustment of the expectation of the cash flow of the indemnified financial asset of the Copel Distribuição concession, originally presented in the line item financial income, would be better classified in the group of operating revenues, together with other revenues related to its activity. This allocation reflects in a better way the business model of electricity distribution and provides a better presentation regarding its performance. As a result, the Company reclassified retrospectively the amountof R$113.4 million from financial revenue to net operating revenue in 2Q16, totaling R$122.4 million in the first half of 2016.

Investments

During the preparation of our unaudited consolidated interim financial information as of September 30, 2017, the Company's Management identified an investment by its indirect subsidiary UEG Araucária Ltda. in a Multimarket Investment Fund, which held shares of other investment funds that in turn invested in a private company, whose main asset was a real estate development. As of September 30, 2017, such investment corresponded to R$157,1 and was recognized under “Bonds and Securities”, in current assets, because, according to information delivered by the management of UEG Araucária to the Company’s Management, that investment was made in a wholly-owned fund, whose benchmark was 103.5% of the CDI (Interbank Deposit Certificate) rate and that was composed of shares issued by other investment funds and government bonds, with immediate liquidity and that were available for sale. This investment amounted to R$165,7 as of December 31, 2016.

In order to determine the value of such investment and its accounting classification, as well as the extent of any possible impact, the Company's Management used independent appraisers and legal advisers in accordance with best governance practices, including an internal investigation into the circumstances of the investment. The valuation has already been concluded and the investigations are in their final stage. These investigations found that the investment occurred strictly in the UEG Araucária and 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.

Based on the information available during the preparation of the consolidated financial statements for 2017, we concluded that it is necessary to recognize a provision for the impairment of the investment in light of its specific characteristics, including the status of its underlying real estate development and the outlook for its future cash flow generation. We also determined that this provision should have been recorded in prior years because the information known during the preparation of those consolidated financial statements was already available at that time and should have been considered in preparing the consolidated financial statements for 2016 and 2015.

In the course of preparing our consolidated financial statements, were analyzed all legal and corporate documents of the investment fund and it was concluded that from July 2015, UEG Araucária started to have significant influence in the private company, even though indirectly. Thus, from July 2015, the remaining balance of the investment, until then classified as a financial instrument measured by its fair value, becamemeasured and disclosed as an associate, and the effects of the change in the asset classification were recorded in the company's profit or loss of that year.

* Amounts subject to rounding.

Supported by a report prepared in March 2018 by independent appraisers engaged by Copel, the Company's Management determined the fair value of the financial instrument as of July 2015 and the remaining balance, already considered as an investment in associates, was reduced by a provision for devaluation, so that the Company's shareholders' equity was reduced by R$125.0 million and non-controlling shareholders by R$31.2 million. The balance of this investment on December 31, 2016 is R$9.6 million.

Until June 31, 2016, the allowance for impairment is R$ 38.0 million, consisting of a negative effect of R$39.1 million as a result of equity in earnings of subsidiaries, R$1.0 milion in financial expenses and the positive effect of R$2.1 million in financial income.

Provision for Contingencies - Taxation regime for sectorial financial assets and liabilities

In 2017, Copel Distribuição recognized prior period adjustments in the account of provisions related to tax litigation due to the taxation of sectorial financial assets and liabilities. The impact of these adjustments represents, on December 31, 2016, an increase of R$32.0 million in provisions for litigation, in non-current liabilities, and an increase of R$10.9 million in deferred tax assets non-current, so that the Company's shareholders' equity was reduced by R$21.1 million.

Tariff Adjustment of Copel Distribuição

Through Resolution No. 2,255 of June 20, 2017, ANEEL approved the tariff adjustment of Copel Distribuição, with an average effect of 5.85% to be noticed by consumers, according to the following table:

This adjustment was fully applied to Copel Distribuição's tariffs as of June 24, 2017. In addition, on June 13, 2017, Aneel rectified the amounts of the Net Remuneration Base by R$30.0 million (from R$4,920.4 million to R$4,950.4 million), and the depreciation amount by R$1.2 million (from R$337.5 million to R$338.7 million). This reconsideration is due to the understanding that the commercial fines imposed on suppliers, due to delays and contractual noncompliance, are not part of the acquisition cost and, therefore, cannot be considered as a benefit for the purchase, since these fines are intended to compensate for possible losses.

* Amounts subject to rounding.

Annual Permitted Revenue - 2017/2018 APR

On June 27, Aneel approved the Annual Permitted Revenue (APR) of the transmission assets of Copel Geração e Transmissão for the 2017/2018 cycle, totaling R$752.5 million, of which R$263.2 million corresponds to RBSE indemnification of agreement 060/2001.

In addition, the concession agreements belonging to the SPCs Transmissora Sul Brasileira, Caiuá, Marumbi, Integração Maranhense, Matrinchã and Guaraciaba underwent their first periodic tariff review.

More details initem 8.2.

Service Provision Revenue (RAG) for 2017/2018

Through Resolution No. 2,265 of July 4, 2017, Aneel has defined the Service Provision Revenues of the hydroelectric power plants under the quota regime, pursuant to Law No. 12,783. As a result, Copel GeT will receive a RAG, related to HPP Gov. Pedro V. Parigot de Souza (GPS), of R$114.1 million. It is worth noting that 30% of the assured power of HPP GPS has been available for sale by Copel GeT since January 1, 2017.

Copel Distribuição - MCSD

In July 2017, the Brazilian Energy Trading Chamber (CCEE) announced the result of the processing of the Compensation Mechanism of Surplus and Deficit (MCSD) of New Energy for 2017. Copel Dis participated in the reduction offer for the Energy Commercialization Agreements in the Regulated Environment (CCEARs), obtaining a reduction in the agreements by 332.3 average-MW for the period between July and December 2017.

Budget Supplementation

The Company's Board of Directors approved, at its 167^th Ordinary Meeting held on June 13, 2017, the budget supplementation for the investment program scheduled for 2017, subject to the proposed funding plan and the effective inflow of financial resources. The goal of this supplementation is to comply with regulatory demands and contractual terms, in order to preserve the flow of resources provided for such ventures. With this supplementation, Capex foreseen for 2017 will be R$ 2,877.5 million. More details initem 5.

HPP Colíder – Construction Work Progress

The project is in the final construction stage, around 93% of the construction works are concluded, including: the dam, the spillway, the water intake and the powerhouse. The manufacturing of equipment and the Plant’s electromechanical assemblies are in progress; the first generation unit is in its final assembly stage.

Due to the delay of suppliers in meeting the equipment delivery, electromechanical assembly service and plant-related transmission line construction schedule, the project schedule was impacted and the operation’s start-up was reviewed. Accordingly, the first generation unit’s start-up is scheduled for April 2018, while the third and last generation unit’s start-up is scheduled for August 2018.

Operational start-up – Voltália São Miguel do Gostoso I Wind Complex

On June 17, 2017, the four wind farms comprising the São Miguel do Gostoso I Wind Complex (Copel 49.0% and Voltália 51%), located in Rio Grande do Norte, were connected to the National Interconnected System (SIN). With 108 MW of installed capacity and assured power of 57.1 average-MW, the Complex was able to start its operations in June 2015, when the construction of the complex was completed. Since then, the complex has received the total revenue of remuneration, in accordance with the public auction held in 2011. See more details inItem 8.

Operational start-up – TL Assis - Londrina

In August 2017, the Assis - Londrina transmission line (500 kV), an enterprise owned by Copel GeT, was put into operation. The circuit, which passes through seven municipalities in the state of Paraná and two municipalities in São Paulo, is 120 km long and will allow for greater energy interchange between the South and Southeast / Midwest regions, contributing to the safety and operational reliability of the national electricity system. The group adds R$18.9 million to COPEL GeT APR. More details inItem 8.2.

2. Financial Performance

The following analyzes refer to the second quarter of 2017 and to the first half of the year compared to the same period of 2016.

2.1 Operating Revenues

In the second quarter of 2017, net operating revenue totaled R$3,173.2 million, a decrease of 16.7%, mainly explained by the 53.5% reduction in the “use of the main distribution and transmission grid” line, arising from the recognition, in 2Q16, of the nonrecurring revenue of R$977.8 million related to the remeasurement of RBSE.

When comparing recurring revenues only, Copel posted a 12.1% increase in net operating revenue in 2Q17, mainly due to (a) the 23.0% increase in “electricity sales to distributors”, as a result of higher revenues in the CCEE, in turn due to a higher average PLD in the period (R$282.96/MWh in 2Q17 vs. R$60.15/MWh in 2Q16) and the higher volume of energy sold in the short-term market by Copel Distribuição; and (b) the positive result of R$67.8 million in sector financial assets and liabilities, due to the increase in hydrological risk (GSF) and the return of charges related to Angra 3, compared to the negative result of R$795.1 million in 2Q16. The following variations are also worth mentioning:

(i) the 26.3% drop in “electricity sales to final customers”, due to the 17.3% decline in the captive market of Copel Distribuição and the 12.9% average reduction applied to the tariffs as of June 24, 2016.

(ii) the 22.3% increase in “revenues from telecommunications”, due to the expansion of services to new customers;

(iii) the 4.5% increase in “other operating revenues”, mainly due to lease and rental revenues and operational and maintenance services; and

(iv) the 1.7% drop in “distribution of piped gas”, due to the decline in natural gas consumption, mainly in the industrial sector, which was partially offset by the adjustment in gas prices.

In the first six months of 2017, Copel’s net operating revenue fell by 6.1%, mainly due the non-recurring revenue of R$977.8 million related to the remeasurement of RBSE. Considering recurring items only, the Company ended the semester with a 6.3% increase in net operating revenue.

* Amounts subject to rounding.

2.2 Operating Costs and Expenses

In 2Q17, operating costs and expenses increased by 13.3%, totaling R$2,699.4 million. This result was mainly due to (a) the 27.0% increase in costs with "electricity purchased for resale”, as a result of the higher hydrological risk (GSF of 82.9% in 2Q17 vs. 89.2% in 2Q16) and the higher average PLD in the period (R$282.96/MWh in 2Q17 vs. R$60.15/MWh in 2Q16); (b) the R$98.5 million in the “provisions and reversals” line in 2Q17, of which: (i) R$31.2 million refers to the impairment of assets of the Bento Miguel Wind Complex, (ii) R$29.0 million to net provisions for labor lawsuits, (iii) R$25.7 million to allowance for doubtful accounts (PECLD), versus a net reversal of R$64.0 million in 2Q16, mainly due to the reversal of R$ 193.4 million related to the process that required the collection of Cofins.

Also noteworthy are the following variations:

(i) the 11.8% increase in the “personnel and management” line, chiefly due to the wage increase as of October 2016 and the R$12.0 million in provision for the voluntary termination and retirement of 59 employees to the Voluntary Redundancy Program (PDI);

(ii) an additional cost in the amount of R$67.0 million in the construction cost line, mainly reflecting the increase in the Capex of the Araraquara-Taubaté transmission line;

(iii) the 34.2% reduction in “charges of the main distribution and transmission grid”, mainly due to the decision of the CCEE to pass on to the market the surplus of resources accumulated in the CONER account - given the prospect of the increase of the PLD throughout 2017 - and the lower costs with reserve energy charges (ERR);

* Amounts subject to rounding.

(iv) the 36.2% drop in “other operating costs and expenses”, mainly due to: (a) the R$21.1 million reduction in costs related to financial compensation for the use of water resources, reflecting the lower generation of hydraulic energy in the period (3,665 GWh in 2Q17 vs. 5,910 GWh in 2Q16); (b) the recovery of R$19.5 million in costs and expenses related to administrative costs, invoices and taxes; and (c) a gain of R$15.4 million related to dividends and interest on own capital from Sanepar, reflecting the change in the valuation method of Copel’s investment in Sanepar; these effects were partially offset by the cost of R$28.2 million related to the state tax on the control and inspection of the use of water resources, pursuant to State Law No. 18,878/2016, which started to be charged as of January 1, 2017.

(v) the 2.8% increase in costs with “natural gas and supplies for the gas business", due to the prices of the oil basket, which determines the gas acquisition price, partially offset by the lower volume of gas acquired in the period;

(vi) the 4.7% decline in "third-party services", due to lower expenses with electricity system maintenance and authorized and accredited agents;

(vii) the 7.2% decline in costs with “pension and healthcare plans”, due to the lower amount invested in the “post-employment plan”, caused by the review of the assumptions that support the actuarial calculation.

In the first half of 2017, operating costs and expenses totaled R$5,207.1 million (1% up). This result was mostly impacted by (a) the 7.2% increase in electricity purchased for resale, caused by the higher PLD; (b) the provision of R$197.2 million, versus R$56.8 million in 1H16; and (c) the 11.5% increase in “personnel and management”, mainly due to the wage increase as of October 2016 and the R$19.2 million in provision for the voluntary termination and retirement of 103 employees to the PDI.These events were partially offset by the 35.3% reduction in "charges of the main distribution and transmission grid", mainly reflecting the lower thermal dispatch outside the merit order.

2.3 Equity in the Earnings of Subsidiaries

Equity in the earnings of investees reflects gains and losses from investments in Copel’s investees and ispresented in the table below.

2.4 EBITDA

In 2Q17, earnings before interest, taxes, depreciation and amortization reached R$707.2 million, 56.3% less than the R$1,618.5 million reported in 2Q16, mainly reflecting the recognition, in 2Q16, of the nonrecurring revenue of R$977.8 million related to the remeasurement of RBSE.

Excluding non-recurring effects, adjusted EBITDA would be 58.1% higher than in the same period of the previous year, basically explained by the result of the 4^th Tariff Review Cycle of Copel Distribuição and by the highest LDP in the period. The following table presents the items considered in the adjusted EBITDA calculation.

* Amounts subject to rounding.

2.5 Financial Result

Financial expenses totaled R$397.5 million, 24.4% higher than 2Q16, reflecting the greater monetary variation on CRC onlendings, the higher exchange variation about purchase Itaipu electric power and the increase in the line of other financial expenses.

In 2Q17, financial revenues totaled R$135.2 million, down 59.5% from the R$333.6 million in 2Q16, mainly related to the lower income from financial investments, as a result of the drop in the Selic rate (average of10.9% p.a. in 2Q17 vs. 14.15% p.a. in 2Q16), the lower income and monetary variation on CRC transferred, due to the lower IGP-DI in the period (negative by 2.71% in 2Q17 vs. positive by 3.12% in 2Q16), and the lower balance related to late fees on electricity bills.

The following table shows these changes and the financial result.

2.6 Consolidated Net Income

In 2Q17, Copel recorded net income of R$151.0 million, 84.3% lower than the R$959.4 million registered in the same period of 2016. This decrease is largely explained by nonrecurring factors in 2Q16 (recognition of the remeasurement of RBSE cash flow and reversal of provisions).

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 Quarterly Financial Information.<0}

3.1 Main Accounts

Cash, Cash Equivalents and Bonds and Securities<0}

On June 30, 2017, the cash and cash equivalents, bonds and securities of Copel’s wholly owned subsidiaries and controlled companies totaled R$1,763.3 million, 27.1% higher than the R$1,386.9 million recorded on December 2016. These funds were invested, mostly in Bank Deposit Certificates (CDBs) and repo transactions. The investments earned an average yield of the period variation in the Interbank Deposit Certificate (CDI) rate.

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.

In accordance with the request by the State of Paraná, approved by the Company's Board of Directors subject to the consent of the Department of the Treasury, the Novation of the CRC Adjustment Agreement is underway, which grants, in the period from April to December 2016, a total grace period for payments and, from January to December 2017, only of the main amount, without any real loss of the total amount of the agreement, maintaining its net present value. The other clauses in the agreement will remain unchanged.

As of January 2017, the State of Paraná resumed the payment of monthly interest installments. However, as the Department of the Treasury has not yet agreed with such Novation and pursuant to the effective terms in the agreement, the Company retained the dividends due to the State of Paraná until obtaining said agreement. The current balance of the CRC is R $ 1,483.4 million.

Other temporary investments

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 Dominó Holdings. Given this fact, the investment of Sanepar which ceased to be classified as an affiliate and is now considered a financial asset available for sale. Accordingly, its recognition is no longer recorded under the equity method, butrather at fair value. On June 30, 2017, the balance of this account amounted to R$487.0 million, R$473.1 million of which is related to Copel’s investment in Sanepar.

* Amounts subject to rounding.

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 June 30, 2017, the Company had a balance of R$463.3 million of sector financial liabilities. More detail in our Quarterly Financial Information (Note 9).

4. Performance of the Main Companies

4.1 Copel Geração e Transmissão

In 2Q17, Copel GeT’s operating revenue fell by 55.4%, totaling R$782.7 million, mainly due to the 87.9% decline in revenues from the "use of the main distribution and transmission grid (TUST)”, which, in 2Q16, benefited from the remeasurement of cash flow of the transmission assets related to RBSE by R$977.8 million. On the other hand, revenues from electricity sales to final customers increased by 7.5%, reflecting the adjustment to the agreements and the higher average PLD (R$282.96/MWh in 2Q17 vs. R$60.15/MWh in 2Q16).

Operating costs and expenses fell by 6.5% in 2Q17, closing the quarter at R$411.6 million, versus the R$440.4 million recorded in 2Q16. This improved performance is mainly a result of (a) the 51.6% reduction in costs with electricity purchased for resale (R$12.1 in 2Q17 vs. R$25.0 million in 2Q16), since, in 2Q17, Copel GeT had more uncontracted energy than in the same period in the previous year (386 average-MW vs. 252 average-MW in 2Q16), partially offset by the lower GSF (82.9% in 2Q17 vs. 89.2% in 2Q16), and (b) the 58% drop in expenses with provisions, mainly provisions for civil and labor lawsuits (R$7.9 million in 2Q17 vs. R$17.8 million in 2Q16) and provison for expropriation (R$0.1 million in 2Q17 vs. 4.0 million in 2Q16).

The decline in operating costs and expenses was partially offset by (a) an additional cost in the amount of R$67.0 million in the construction cost line, mainly due to the increase in the Capex of the Araraquara II – Taubaté transmission line; (b) the 12.9% increase in “charges of the main distribution and transmission grid”, due to the start-up of new transmission assets and the APR adjustment in July 2016; and (c) the 12.0% increase in “personnel and management”, as a result of the wage increase as of October 2016 and the R$1.9 million in provision for the voluntary termination of 11 employees between April and June 2017.

Equity in the earnings of investees was negative by R$20.8 million over a positive R$3.7 million in 2Q16, chiefly impacted by the negative result of R$23.0 million at the Araucária TPP and the impairment of R$31.2 million from the Bento Miguel Wind Complex. In 2Q17, Copel GeT reported net income of R$146.9 million and EBITDA of R$419.2 million.

* Amounts subject to rounding.

In the first six months of 2017, Copel GeT’s operating revenue reached R$1,856.2 million, 25.9% down from the same period in the previous year, while operating costs and expenses grew by 1.6%, totaling R$844.8 million in the period. Net income reached R$489.8 million and EBITDA totaled R$1,133.1 million, 50.1% and 38.3% down from the first half of 2016, respectively.

Copel GeT’s - Adjusted EBITDA

Excluding nonrecurring effects of the period, EBITDA Copel GeT would be 3.6% higher than recorded in same period in 2016.

4.2 Copel Distribuição

In the second quarter of 2017, Copel Distribuição’s operating revenue increased by 17.2%, reaching R$2,160.7 million, mainly due to the positive result of R$67.8 million in sector financial assets and liabilities, versus the negative R$727.3 million in 2Q16. Moreover, the operating revenue of the subsidiary was also positively impacted by the 81.9% upturn in the electricity sales to distributors revenue (R$243.8 million in 2Q17 vs. R$134.1 million in 2Q16), as a result of the higher volume of energy sold in the short term (1,016 GWh in 2Q17 vs. 642 GWh in 2Q16) and the higher average PLD (R$282.96/MWh in 2Q17 vs. R$60.15/MWh in 2Q16).

This increase was partially offset by (a) the 31.5% reduction in the revenue from electricity sales to final customers, due to the 17.3% drop in the captive market, as a result of the migration of consumers to the free market and the average 12.9% decline in tariffs as of June 24, 2016; (b) the reduction in the “fair value of assets from the indemnity for the concession" line, due to the result of the 4^th Tariff Review Cycle of Copel Distribuição in June 2016, which resulted in the drop from R$113.1 million in 2Q16 to R$1.3 million in 2Q17; and (c) the 4.5% drop in revenue from the use of the main distribution and transmission grid (TUSD), explained by the result of the 4th Cycle of Periodic Tariff Review, of June 2016, which reduced TUSD by 5.16%.

* Amounts subject to rounding.

Operating costs and expenses grew by 6.6%, reaching R$2,098.1 million in 2Q17 and mainly reflecting the 24.4% increase in costs with electricity purchased for resale, mainly due to the costs generated by the greater hydrological risk of the period (GSF of 82.9% in 2Q17 compared to 89.2% in 2Q16) and the 9.4% growth in personnel and management costs, as a result of the wage increase in October 2016 and the R$5.6 million in provision for the voluntary termination of 34 employees in 2Q17.

The increase in operating costs and expenses was partially offset by (a) the 49.3% decline in charges of the main distribution and transmission grid, due to the CCEE's decision to pass on to the market the surplus of resources accumulated in the CONER account, given the prospect of a PLD increase in 2017 and the lower cost with reserve energy charge (EER); (b) the recording of R$54.4 million in provisions and reversals (versus R$106.3 million in 2Q16), of which R$24.2 million to labor lawsuits, R$22.8 million is related to allowance for doubtful accounts (PECLD) and R$7.4 million to civil and administrative, regulatory, tax and environmental lawsuits.

The financial result ended the quarter negative by R$39.4 million, versus positive R$26,1 million in 2Q16. Thus, Copel Distribuição recorded a net profit of R$7.9 million and EBITDA of R$134.9 million in 2Q17.

In the first six months of 2017, Copel Distribuição recorded net revenue of R$4,165.0 million, 6.0% up on the same period in 2016. Operating costs and expenses fell by 3.9%, reaching R$3,980.1 million up to June 2017. Thus, the Company recorded a net profit of R$79.2 million, versus a loss of R$103.4 in the same period of 2016. EBITDA was positive by R$328.1 million, versus a negative EBITDA of R$76.0 million up to June 2016. The improvement in the figures for the first half of 2017 was chiefly due to the result of the 4^th Tariff Review Cycle, the 2.0% increase in the grid market, and the lower provision balance.

In the last 12 months, the period corresponding to the 1st year after the Copel's 4th Tariff Cycle, EBITDA was R$ 520.7 million.

* Amounts subject to rounding.

4.3 Copel Telecomunicações

Copel Telecomunicações’ operating revenue reached R$93.1 million in 2Q17, 18.8% up, mainly reflecting the expansion of the area of operation and services to new customers. Operating costs and expenses grew by 21.9%, to R$65.9 million, mainly influenced by (a) the 48.8% increase in costs with third-party services, which are necessary to expand the area of operation; (b) the 45.3% increase in other operating costs and expenses, mainly due to higher costs with advertising and marketing; (c) the 11.3% increase in personnel and management costs, as a result of the wage increase in October 2016. Net income for the period grew by 5.9%, totaling R$15.6 million, while EBITDA increased by 12.3%, totaling R$36.9 million.

Until June 2017, Copel Telecom had posted a 15.6% increase in operating revenue in relation to the same period of 2016, totaling R$180.8 million, while operating costs and expenses reached R$131.5 million, a 17.9% increase in the period. Copel Telecom reported net income of R$27.2 million in the first half of 2017, 4.7% higher than the R$25.9 million reported in the same period of 2016, while EBITDA increased by 10.5% in the period, to R$68.4 million.

Under Construction

Copel Geração e Transmissão

Copel GeT is building two hydroelectric power plants that will add 405 MW to its total installed capacity, as described below.

Colíder Hydroelectric Power Plant

In July 2010, Copel won the Aneel auction for the 35-year concession to build and operate the Colíder Hydroelectric Power Plant, in the Teles Pires river, in the state of Mato Grosso. The Colíder HPP will have an installed capacity of 300.0 MW and is located between the cities of Nova Canaã do Norte and Itaúba, with the cities of Colíder and Cláudia also being served by the future unit. The construction of the plant began in 2011 and around 93% of the works are complete. The dam, the spillway, the water supply and the powerhouse are concluded. The equipment manufacturing and the electromechanical assemblies of the plant are in progress, and the Generating Unit 01 is in its final assembly phase, and the works of deployment of the 64 km long transmission line, which will connect the To the Cláudia substation, are in fast pace.

As a result of force majeure and government acts during the implementation of the Colíder HPP, Copel Geração e Transmissão requested with Aneel a waiver of responsibility, totaling 644 days, related to the delay in the plant’s startup, initially scheduled for December 30, 2014. Copel GeT honored the Colíder HPP’s CCEAR commitments, totaling 125 average-MW, using uncontracted energy surplus from its other plants.

In October 2015, the Regional Federal Appellate Court of the 1st Region granted Copel GeT a preliminary relief exempting it from fines, penalties, charges and other burdens until the waiver of responsibility request is settled with ANEEL. The request was denied in June 2016, so Copel GeT filed an administrative appeal at Aneel, requesting the reconsideration of the ruling.

In March 2017, Aneel denied the administrative appeal of Copel GeT, but Copel submitted Aneel's ruling to the Regional Federal Court of the 1st Region, questioning the decision given that, from Copel's point of view, Aneel had not depleted the analysis of the request for reconsideration. The Court Judge of Appeals Souza Prudente complied with Copel's request and ruled in favor of maintaining the effects of the preliminary protection issued in October 2015. Finally, in early July 2017, Aneel tried and definitively denied Copel's lawsuit. However,considering the reasons that impacted the plant’s scheduled startup - force majeure and government acts during the implementation of the project - Copel will forward the matter to the Judiciary.

* Amounts subject to rounding.

The first generating unit’s startup is scheduled for April 2018, while the third and final generating unit is scheduled to go into operation in August 2018.

From a total assured power of 178.9 average-MW, established by MME (Ministry of Mines and Energy) Ordinance 213 of July 14, 2017, 125.0 average-MW are committed under a 30-year agreement, for the price of R$103.40/MWh, as of July 1, 2010 (annually adjusted by the IPCA consumer price index). The remaining 53.1 average-MW not sold under this agreement have not yet been contracted and are available for sale to large consumers in the free market.

On January 26, 2017, the Brazilian Energy Trading Chamber (CCEE) announced the results of the annual processing of the Compensation Mechanism of Surplus and Deficit (MCSD) of New Energy for the product from January 1 to December 31, 2017. Copel GeT participated in the reduction offer for the Colíder HPP’s Energy Commercialization Agreements in the Regulated Environment (CCEARs), obtaining a full reduction of the agreements (125 average-MW).

In addition, on February, 2017, the Energy Trading Chamber - CCEE announced the result of the processing of the new statements, backdating to 2016, for the MCSD of New Energy from July to December 2016. Copel GeT participated in the reduction offer of the Electric Power Trading Agreements in the Regulated Environment - CCEARs (Contratos de Comercialização de Energia no Ambiente Regulado) of the HPP Colíder, obtaining the reduction of the agreements in its entirety (average of 125 MW) from July 2016.

It should be noted that due to the preliminary protection issued by the TRF of the 1st Region, in October 2015, Copel GeT was already relieved to deliver the energy of the CCEARs in that period.

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 350.20 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.

* Amounts subject to rounding.

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, in August 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.

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.

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

Operating Data

In the distribution business, Copel serves more than 4.5 million energy customers in 1,113 locations, belonging to 394 municipalities in State of Paraná and one in the State of Santa Catarina. Copel Distribuição operates and maintains the installations in the 13.8 kV, 34.5 kV, 69 kV, 138 kV and some of 230 kV voltage levels.

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 June 2017, the total length of compact-design distribution lines in operation was 9,211 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 June 2017 at 16,789 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.
