6.1. Production Capacities

On the results of the 2010 fiscal year, the installed capacity of the Company’s power plants equaled to the 6,278.1MW electric capacity and the 14,368 Gcal/h heat capacity including the affiliate Murmanskaya CHPP.


Installed capacity changes for 2010
Increased at the following plants:
• Lesogorskaya HPP of the Vuoksinskiye HPPs Cascade by 6MW due to the remarking of the hydroelectric unit of station No. 1 after
the updating;
• Svetogorskaya HPP of the Vuoksinskiye HPPs Cascade by 7.25MW due to the remarking of the hydroelectric unit of station No. 1
after the updating;
• HPP Khiamekoski of the Sunskiye HPPs Cascade by 0.9MW due to the commissioning of hydroelectric unit No. 3 after the renovation.

Decreased at the following plants:
• Yuzhnaya CHPP due to the decommissioning of the gas-turbine unit (GTU) of the 50MW installed capacity;
• Narvskaya HPP by 0.2MW due to bringing the installed capacity to conformity with the data of the manufacturer’s certificates for hydroelectric units;
• HPP Janiskoski by 0.3MW due to the decommissioning of the auxiliary generator of hydroelectric unit No. 3.

Available capacity changes for the whole year
Increased at the following plants:
• Volkhovskaya HPP of the Ladozhskiye HPPs Cascade owing to the decrease in the extent of seasonal constraints;
• Lesogorskaya HPP of the Vuoksinskiye HPPs Cascade due to the remarking of the hydroelectric unit of station No. 1 after the
updating;
• Svetogorskaya HPP of the Vuoksinskiye HPPs Cascade due to the hydroelectric unit remarking after its updating and the decrease
in engineering constraints. Decreased at the following plants:
• Dubrovskaya CHPP due to the increase in the extent of seasonal constraints;
• Pervomayskaya CHPP due to the execution of engineering constraints at the turbine unit of station No. 6;
• Narvskaya HPP due to the decrease in the plant installed capacity.

The available capacity decrease in HPPs as of the year end versus the year beginning is accounted for the smaller water afflux.


6.2. Electricity Generation

As of the end of 2010, the installed capacity of the Company’s power plants equaled to the 6,278.1MW electric capacity and the
14,368 Gcal/h heat capacity including the affiliate Murmanskaya CHPP.

The JSC TGC-1 production capacities comprised 56 power plants, in particular: 41 HPPs including Luzhskaya HPP of the 540 kW installed electric capacity, 14 CHPPs including the affiliate Murmanskaya CHPP, and 1 diesel power plant (DPP).

In 2010, the overall electricity generation by JSC TGC-1 increased by 1.5% in comparison with the similar indicator of 2009. The generation by the Nevsky Branch increased by 5.2%, the same by the Karelsky Branch decreased by 7.3%, and by the Kolsky Branch decreased by 1.1%. The electricity generation increase at CHPP made 11.52% versus 2009; while the generation decrease at HPP made 7.4%.

The installed electric capacity efficiency ratio for JSC TGC-1 on the whole made 49.3% in 2010; it was registered at the level of 50.9% for HPP, and 47.9% for CHPP.



The increase in generation on the results of the 2010 fiscal year is connected with the greatly grown generation at thermal power plants that was caused by the considerably colder autumn-andwinter period and the increased demand for electricity on the wholesale market, while the decrease in the HPP generation is accounted for the low water content in 2010.





6.3. Heat Generation

The heat output from the TGC-1 collecting headers increased in 2010 by 7.1% versus 2009, due to low temperatures within the heating season.

The heat output increase by the branches: Nevsky – 7.8%, Karelsky – 7.0%, Kolsky 5.3%, and Murmanskaya CHPP – 1.4%.




6.4. Analysis of Fuel Consumption in CHPPs of JSC TGC-1

On the results of the 2010 fiscal year, the specific reference fuel consumption for delivered heat decreased made 138.4 kg/Gcal, which is 0.3% less than the similar indicator in 2009. The specific reference fuel consumption for delivered electricity increased by 0.3 % for the whole year up to 301.4 g/kWh.

The causes of the increase in the specific reference fuel consumption for delivered electricity were as follows:

– the reduction of the percentage of electricity generation by the cogeneration cycle due to the leading growth in electricity generation over the heat output;
– the peak-type schedule of electric loading. The utilization of “condensation tails” of the cogeneration turbine units for covering the electric load schedules;
– the increase in power consumption for own needs due to employment of extra units of auxiliary equipment.



6.5. Energy Saving and Energy Efficiency

In 2010, on the results of the measures for energy efficiency enhancement and reduction of the costs of process and operational nature, the following volumes were saved:

– 30,945 tonnes of fuel equivalent (TOE) in Nevsky Branch;
– 2,330 TOE and 605 thousand kWh in Karelsky Branch;
– 435 thousand kWh in Kolsky Branch.

The replacement of filament lamps with energy-efficient ones
is under process at the power facilities of JSC TGC-1. The lamp
replacement effect is as high as 1,263 thousand kWh in 2010.


6.6. Repair and Maintenance Programme

In 2010, shutdowns of ten power plants and their stages of the Nevsky Branch and Petrozavodskaya CHPP of the Karelsky Branch were carried out within the summer period in order to perform scheduled repair of the hot water supply and cogeneration systems, general plant equipment, pipelines, and facilities.
