Operating results

In 2017, electricity generation by RusHydro Group and Boguchanskaya hydropower plant has set an all-time high record of 140,249 GWh. Total electricity generation by power plants of RusHydro Group in 4Q 2017 amounted to 32,384 GWh (+5.5%), in 2017 – 126,961 GWh (+1.7%). In 4Q 2017, total production by hydropower and pumped storage plants amounted to 23,118 GWh (+4.5%), total output by fossil fuel and geothermal plants – 9,266 GWh (+7.7%). In 2017, total production by hydropower and pumped storage plants amounted to 95,971 GWh (+1.0%), total output by fossil fuel and geothermal plants – 30,991 GWh (+3.6%).

Main factors, determining operating results in 2017, were:

• total water inflow to reservoirs of the hydropower plants of the Volga-Kama cascade significantly higher than long-run average;

• commissioning of Yakutskaya GRES-2 in autumn of 2017 as well as Blagoveshenskaya CHP (second stage) and hybrid Zelenchukskaya HPP-PSPP gradually reaching full production capacity;

• decrease in water inflows to hydropower plants of the South of Russia, Siberia and the Far East as compared to 2016 to long-run average levels.

In 2017, heat output by thermal plants of RusHydro Group in the Far East decreased by 5% to 29,924 thousand GCal as compared to the same period of 2016. The decrease is due to higher temperatures and reduced length of heating season in a number of towns of the Far East.

In the 2017, total electricity output by RusHydro Group’s electricity retail companies, operating in Chuvashia, Ryazan and Krasnoyarsk regions (ESC RusHydro subgroup), amounted to 20,717 GWh, a 5.5% decrease as compared to the same period of 2016. A number of consumers switching to wholesale electricity purchases (primarily in Krasnoyarsk region), higher temperatures and other factors are the main reasons for the decrease in output.

Revenue

Revenue breakdown in 4Q and 2017/2016 (in RUB mn)

Comparable 4Q and 2017/2016 revenue (in RUB mn), excl. LLC ESC Bashkortostan^[1]

In 2017, total revenue of the Group decreased by 2.7%, which was mostly a result of divestment of LLC ESC Bashkortostan in December 2016. Comparable revenue, excluding the effect of LLC ESC Bashkortostan sale, increased by 5.4%. The change is associated with the following key factors:

• increase in revenue from capacity sales following commissioning of Zelenchukskaya hybrid hydropower plant in Karachayevo-Cherkessia, sold under capacity delivery agreement;

• increase in revenue from capacity sales of PJSC RusHydro at the competitive capacity auctions (KOM) for the hydropower plants in the first and second price zones, liberalization of hydro capacity market of Siberia with the growth of share of capacity sold under KOM tariffs to 100% from May 1, 2016;

• increase in day-ahead-market (DAM) price in the second price zone on the back of decrease in hydropower production along with supply increase of thermal generation;

• increase in revenue of JSC DRSK as a result of growth of tariffs in Khabarovsk region, Primorsky Kray, Evreysky autonomous region and South of Yakutia;

• increase in revenue of PJSC Yakutskenergo driven for the most part by increase of transmission revenue of third-party electricity under the agreement with JSC Viluyskaya GES-3, a guaranteed electricity supplier for PJSC ALROSA facilities that have seen an increase in electricity consumption.

Operating expenses in 4Q and 2017/2016 (in RUB mn)

Comparable 4Q and 2017/2016 operating expenses (in RUB mn), excl. LLC ESC Bashkortostan^[1]

Total operating expenses in 2017 compared to 2016 decreased by 3.8% to RUB 303,805 mn, which was mostly a result of divestment of LLC ESC Bashkortostan in December 2016 with total operating expenses in 2016 of RUB 27,972 mn. Comparable operating expenses excluding the effect of LLC ESC Bashkortostan sale were up 5.6% due to the following factors.

• increase in electricity distribution expenses due to tariffs increase and higher volumes of electricity transmission due to increase of useful output of ESC RusHydro subgroup as well as RAO ES East subgroup;

• increase in fuel expenses mostly due to fuel cost increase of JSC DGK and increase in electricity output of JSC DGK in 2017 compared to 2016;

• increase in employee benefit expenses as a result of indexation of remuneration of the operating personnel in compliance with collective agreements;

• increase in depreciation of property, plant and equipment and amortization of intangible assets.

Profit

In the reporting period, EBITDA increased by 3.7% to RUB 104,038 mn compared to the same period of previous year.

In 2017, the Group’s net profit decreased by 43.5% to RUB 22,451 mn. Adjusted net profit in the reporting period amounted to RUB 62,702 – 2.6% decrease as compared to the same period of the previous year. Comparable net profit in 2017 excluding contribution of LLC ESC Bashkortostan remained flat year-on-year.

The difference between the reported and adjusted profit is attributed mainly to the following non-cash effects (before income tax) and recognition of change in fair value of the derivative financial instrument:

• impairment of property, plant & equipment in the amount of RUB 24,000 primarily in relation to Yakutskaya GRES-2 and PJSC Yakutskenergo as a result of insufficient tariff revenue generation under the current tariff regulation;

• financial expense in the amount of RUB 13,946 mn as a result of change in fair value of non-deliverable forward contract as a result of reduction of market price of RusHydro’s shares in the reporting period;

• impairment of accounts receivable in the amount of RUB 5,957 mn resulting from analysis of overdue receivables and estimation of their collectability.

In addition, the recognition of one-off income in 2016 from the sale of LLC ESC Bashkortostan in the amount of RUB 3,048 mn, the sale of dams of Bratskaya, Ust’-Ilimskaya and Irkutskaya HPPs in the amount of RUB 7,202 mn as well as insurance indemnity in respect to Zagorskaya PSP-2 in the amount of RUB 1,737 mn had an effect on the change of net profit and adjusted net profit in 2017 as compared to 2016.

Key indicators of financial position

As of December 31, 2017, the Group's assets increased by RUB 44,805 mn or 4.6% to RUB 1,028,251 mn against the comparable figure as at December 31, 2016. Change in assets is primarily attributable to:

• increase in fixed assets of the Group;

• increase in accounts receivable and inventories;

• increase in value of cash and cash equivalent.

As at the end of the reporting period, the Group's liabilities were RUB 332,687 mn. The structure of liabilities has changed accordingly: long-term liabilities decreased by RUB 34,419 mn and short-term liabilities increased by RUB 34,592 mn mainly due to reclassification of long-term debt into short-term as a result of approaching redemption date.

Structure of the liabilities of the Group underwent significant changes:

• proceeds from the share issue and sale of treasury shares were fully allocated to repayment of loans of RAO ES East subgroup;

• partial redemption of bonds issued in April, 2015 within offer;

• placement of eurobond issue in the amount of RUB 20 bn;

• in accordance with conditions of non-deliverable forward contract with PJSC VTB Bank, the Group recognized liabilities under the contract, recorded as a long-term derivative financial instrument at fair value by using the Monte Carlo model. The main reason of the change in fair value of the forward contract is the local dynamics in the change of market price of RusHydro’s shares in 2017. Therefore, an increase in the market price of RusHydro’s shares in the forthcoming reporting periods will reduce the fair value of the forward contract.

Events after the reporting date

• On February 7, 2018, RusHydro Group’s financial debt went down by RUB 26 bn following exclusion of guarantee obligation between PJSC RusHydro and State Corporation ‘Vnesheconombank’ on PJSC Boguchanskaya HPP loan given out by the bank in 2010. The lending bank supported the termination following construction completion and HPP reaching full capacity, PJSC Boguchanskaya HPP’s stable financial and operational results and its ability to service the loan independently. Therefore, the Group’s total debt load decreased significantly.

• On February 15, 2018 PJSC RusHydro has successfully placed loan participation notes (LPNs) issued by RusHydro Capital Markets DAC. RusHydro will use the proceeds from the RUB 20 bn Eurobond issue to refinance its current loan portfolio and for general corporate purposes. The LPNs will mature in 2021 and bear an interest rate of 7.40% per annum. The following ratings have been assigned to the issue: S&P: “BB+” / Moody's: ‘Ba1’ / Fitch: ’BB+’ / ACRA ‘AAA(RU)’.

• On February 27, 2018 Standard & Poor's Global Ratings Services raised long-term corporate credit ratings on PJSC RusHydro to ‘BBB-’ with ‘Stable’ outlook. Short-term corporate credit was raised to ‘À-3’ respectively.
