• water inflow to major reservoirs of Siberia in the 1^st half of 2016 was close to normal;

• increased electricity generation by hydropower plants of the South of Russia associated with water level close to long-run average;

• decrease in electricity generation by TPPs of RAO ES of East Holding due to higher electricity generation by hydropower plants of the Far East.
  
  

Center of Russia

In the 2^nd quarter of 2016, water inflow to reservoirs located at the Upper Volga was 20-35% lower than long-run average, to Volgogradskoe reservoir – only 25% of norm, to Gorkovskoe, Cheboksarskoe, Kuybyshevskoe and Nizhnekamskoe reservoirs – close to normal, to Kamskoe and Votkinskoe reservoirs – 25-65% higher than long-run average.

Total water inflow to reservoirs of the Volgo-Kama cascade in the 1^st half of 2016 amounted to 194.1 km³ as compared to the average of 183.3 km³.

Total electricity generation by RusHydro’s hydropower plants of the Volgo-Kama cascade together with Zagorskaya pumped storage plant in the 2^nd quarter of 2016 amounted to 12,686 GWh, a 12.2% increase as compared to the same period of 2015. In the 1^st half of 2016, generation reached 22,485 GWh, which is 22.8% higher than in the same period of the previous year.

South of Russia and North Caucasus

Water conditions on the rivers of the South of Russia and North Caucasus in the 1^st half of 2016 were close to long-run average. In the 1^st and 2^nd quarters of 2016 water inflow to the Chirkeyskoe reservoir was 15% higher than long-run average. Hydropower plants of the Dagestan branch of RusHydro successfully went through the peak flood period, which took place in the first decade of June. According to preliminary forecast, the flood period in the basin of the Sulak river will last till the end of July.

Due to high water inflows the Irganayskaya HPP has been drown down from the end of June in order to create reserve capacity of reservoir.

The electricity generation by the hydropower plants of the South of Russia and North Caucasus in the 2^nd quarter of 2016 increased by 12.9% to 2,587 GWh, in the 1^st half of 2016 – by 25.8% to 4,186 GWh.

Siberia

In the 1^st half of 2016, water inflow to the Ob and Yenisei rivers was close to normal. In 2016, the spring flood period in the basin of the Sayano-Shushenskaya HPP started later than usual, water inflow in the 2^nd quarter of 2016 amounted to 2,620 m³/s as compared to long-run average of 2,570 m³/s. The flood period in the basin of Novosibirskoe reservoir started earlier than usual; currently the flood is slowing down.

The Boguchanskaya hydropower plant in the 1^st half of 2016 generated 6,491 GWh, 8.8% increase as compared to the same period of the previous year. Due to low water inflow forecast and water storage in reservoirs of the Angara cascade the navigation below the dam of the Boguchanskaya HPP might be limited.

Total electricity generation by RusHydro’s Siberian hydropower plants in the 2^nd quarter of 2016 increased by 4.8% to 6,676 GWh, in the 1^st half of 2016 –by 6.9% to 12,319 GWh.

Far East

In the 2^nd quarter of 2016, water inflow to Kolymskoe reservoir was 25% lower than long-run average, to reservoir of the Zeyskaya HPP – 60% higher than normal. In order to provide for safe and uninterrupted operation of hydropower facilities during the flood period, the spare capacity was created in reservoirs to accumulate spring and summer inflows.

In 2016, unlike two previous years, the reservoir of the Zeyskaya HPP is expected to be filled over its normal water level of 315 m and limitations of output will be removed allowing the plant to reach its annual output of 4.3 TWh.

Total electricity generated by hydro and geothermal power plants of the Far East in the 2^nd quarter of 2016, increased by 6.4% to 3,279 GWh. In the 1^st half of 2016, the generation increased by 13.2% to 6,709 GWh.

In the 2^nd quarter of 2016, generating assets of RAO ES of the East Holding, a subsidiary of RusHydro, produced 6,961 GWh of electricity, a 4.4% decrease as compared to the 2^nd quarter of 2015, in the 1^st half of 2016 generation decreased by 3.5% and amounted to 17,195 GWh. Of this total, 76% was generated by JSC Far East Generating Company (DGK), which decreased production by 4.1% in the 1^st half of 2016 to 13,029 GWh, mainly due to 15% increase in electricity output by the Zeyskaya and Bureyskaya hydropower plants. In the 1^st half of 2016, electricity generation by companies operating in isolated energy systems of the Far East remained flat year-on-year.

In the 1^st half of 2016, heat output by thermal plants of RAO ES of the East increased by 4.2% to 18,259 ths. GCal as compared to the same period of 2015.

Armenia

In the 2^nd quarter of 2016, electricity generation by the Sevan-Hrazdan cascade of hydropower plants in Armenia decreased by 29.6% to 144 GWh, in the 1^st half of 2016, electricity generation decreased by 16.8% to 216 GWh. Power generation by the plants of the cascade is dependent on water inflows of the Hrazdan river and water releases from Sevan lake.

Electricity retail

In the 2^nd quarter of 2016, total electricity output by RusHydro’s four retail companies, operating in Bashkiria, Chuvashia, Ryazan and Krasnoyarsk regions, amounted to 7,593 GWh, a 4% decrease as compared to the same period of 2015; in the 1^st half of 2016 output amounted to 17,798 GWh (-4%).

In the reporting period ESC RusHydro, a holding company for all electricity retail operations, increased electricity output by 186 GWh (+21.4%) as compared to the same period of 2015 due to addition of major consumers.

The decrease in electricity output by JSC Krasnoyarskenergosbyt by 145 GWh or 2%, Bashkiria power retail company by 650 GWh (-9%), JSC Chuvash retail company by 26 GW (-1.5%) and PJSC Ryazan retail company by 41 GWh (-3%) is attributable to recession in manufacturing industry as well as transfer of a number of major consumers to independent wholesale electricity purchases.

Water inflows forecast

According to the forecast of the Hydrometeorologic Center of Russia, the following dynamics of water inflows to the major reservoirs is expected in the 3^rd quarter of 2016:

• total expected water inflow to reservoirs of the Volgo-Kama may amount to 33-41 km³ as compared to the average of 37.0 km³;

• water inflow to the reservoirs of hydropower plants located in the North Caucasus is expected to be close to long-run average;

• water inflow to major reservoirs of hydropower plants of Siberia expected to be close to normal;

• water inflow to the HPP’s of the Far East is expected to be close to long-run average, to reservoir of the Zeyskaya HPP – 25-45% higher than normal.
