According to the results for 2010, the revenue from the sale of goods and services increased by 12.6% to 88,979 million roubles, compared to 78,996 million roubles in 2009. The main factors behind the revenue growth in 2010 were:

 -  increase in the share of sales at unregulated prices in accordance with the time schedule for liberalization of the wholesale market for electricity and capacity;

 -  increased electricity prices on the free market (day-ahead market and balancing market);

 -  increased volume of electricity sold under free bilateral contracts.

The major part of the Company's revenue is represented by the sales of electricity and capacity:

The cost of goods and services sold (COGS) amounted to 45,369 million roubles in 2010, a 23.6% increase compared to 2009.

The main factor behind the increase in COGS was increase in cost of purchased electricity and capacity from 8,578 million to 14,776 million, including purchases of electricity from wholesale market under free bilateral contracts.

As a result of increase in revenue and in COGS in 2010 the Company's gross profit rose by 3.1% y-o-y and amounted to 43,610 million roubles.

The main factor behind the increase in other income and other costs was novation of debt on promissory notes of RusHydro Group subsidiaries and associates.

The EBITDA in 2010 rose over 2009 by 2.7% to reach 51,754 million roubles. 

EBITDA margin amounted to 58.2% as compared to 63.8 % a year earlier.

RusHydro's net profit in accordance with the Russian Accounting Standards rose y-o-y by 267.5% to 37,963 million roubles.  The main reason for the increase in net profit in 2010 was revaluation of the stake in JSC OGK-1 marked to market, resulting in 4,691 million roubles income, while in 2009 due to negative market trends and sharp decline in the value of JSC OGK-1 shares loss of 21,683 million roubles was booked.
