RusHydro Group increased electricity generation in the I quarter of 2013 by 15%

In the first quarter of 2013 the total electricity generation stations of JSC "RusHydro" subsidiaries and affiliates amounted to 31,962 million kWh, which is 15% more than the same period in 2012.

Hydroelectric power plants in the group RusHydro, January-March 2013 increased the production of electricity by 27% compared to the same period last year.

The main factors that contributed to the variation of RusHydro Group in the 1st quarter of 2013 were: increased water storage in reservoirs hydropower plants of the Far East and Central Russia at the beginning of 2013, in connection with those observed at the end of autumn 2012 floods, the water inflow into the reservoir Volga-Kama cascade above long-term averages, the inflow of water into the main reservoir hydropower plant in Siberia slightly above or at the level of the norm; Commissioning Boguchan plant at the end of 2012.

Net capacity of reservoirs of the Volga-Kama cascade at the beginning of 2013 to 69 km3, which is above the average annual values of 32%, and 54% higher than last year.

The total inflow of water in the reservoirs of the Volga-Kama cascade in the first quarter amounted to 29 km3 at a rate of 21.3 km3. By the end of Q1 2013 reserves of water in the snow cover in the Volga basin exceeded the average long-term value by 24%.

In April, the inflow of water in most reservoirs cascade is expected to be 20-70% more than normal for this time of year.

RusHydro's total output stations of the Volga-Kama cascade and Zagorskaya the PSP in the first quarter of 2013 amounted to 10,057 million kWh, which is 32% higher than in 2012.

Siberia

The inflow of water in the Sayano-Shushenskaya dam in the 1st quarter of 2013 was 10% above long-term averages. Sayano-Shushenskaya hydroelectric power station operates in the mode that provides the Sayano-Shushenskaya drawdown of the reservoir to the level of at least 500 m long, idle discharge of water. According to the forecast inflow into the Sayano-Shushenskaya dam in April is expected to be 37% more than the average annual values in the 2nd quarter — 11%.

By the end of the 1st quarter of the Novosibirsk reservoir level was 108.2 m, which is 30 cm below the EMA (dead storage level — the minimum reservoir level to which it is possible drawdown in normal operation).

As of the end of Q1 2013 supplies of water in the snow cover in the basins of the power plant and the Novosibirsk plant exceeded the norm by 32% and 38%, respectively. On the basis of these data, it can be expected that the high water on the Siberian rivers will be higher than normal.

The inflow of water in the Sayano-Shushenskaya dam is expected in April at a rate of 1.4-2.3 km3 1.53 km3 in the 2nd quarter of 19-24 km3 at a rate of 20 km3.

Boguchan plant is currently operating in the mode that provides Boguchansky maintain the level of the reservoir at around 185 m

In Siberia hydroelectric power generation group RusHydro in Q1 2013 increased 18% to 6,622 million kWh.

South and North Caucasus

Water availability in the rivers of the North Caucasus in the 1st quarter of 2013 was generally average or below average.

The inflow of water in the Krasnodar Reservoir in the first quarter of 2013 was less than the norm of 35%, a tributary to the Vladikavkaz and Chirkeisk plant close to it. In the 2nd quarter of 2013, the inflow of water in the Krasnodar Reservoir, to Vladikavkaz and Chirkeisk plant will be close to normal.

The main power plant in the region are now working in the mode of reservoir drawdown. Electric power generation plant of the South Russia and the North Caucasus in the 1st quarter of 2013 increased by 35% to 1,421 million kWh.

Far East

The inflow of water in the Zeya reservoir in the 1st quarter of 2013 was 45% above normal in Boureisk Reservoir — close to it.

Currently under drawdown Zeya and Bureyskiy reservoirs before reaching elevations safe spring floods.

Sverhbalansovaya power generation plant of the Far East for the first quarter of 2013 amounted to 940 million kWh (on the balance of FTS) and was provided both through additional sales to China, and due to the discharge of thermal generation. East in the 1st quarter rose 26% to 4,122 million kWh.

Generating assets of the holding RAO ES of the East, in the 1st quarter of 2013 developed the 9,657 million kWh of electricity, which is 5% lower than in Q1 2012.

The structure of electricity generation RAO ES of the East during the reporting period accounted for 73% of the Far Eastern Generating Company, which reduced production compared with 2012 by 6% mainly due to the higher loading of hydroelectric power. Electricity production in the 1st quarter of 2013 in isolated power and other generating assets of RAO ES of the East amounted to 2,563 million kWh, a decrease of 4%.

Heat energy generating assets of RAO ES of the East in the 1st quarter of 2013 decreased by 1% to 14,042 thousand GKalch.

Armenia

Electricity generation at the Sevan-Hrazdan cascade hydropower stations in Armenia in the 1st quarter of 2013 increased by 54% to $ 84 million kWh. The development of plants is caused by a cascade of natural inflow in the Hrazdan River, and water releases from Lake Sevan.
