OREANDA-NEWS. May 6, 2009. Generation company of Tatarstan power holding keeps the positive dynamics of economic performance under conditions of operation on the market.

The economic performance (EP) of generation allow to depict the cost-efficiency of production and energy supply, which under competition is the priority of the power market operators with keeping the reliable electricity and heat supply to each consumer group.

Since 2003 the absolute figures regarding the cost-efficiency of electricity supply in are better than the average in the industry. The positive dynamics in JSC "Generation Company" of Tatarstan power holding is kept under conditions of operation on the electricity market. This was reached due to increased technical and technological actions, realized at the separate plants and in the entire company, and increase of the share of loading the unit condensing equipment and commissioning the GT at Kazan CHP-1.

Electricity consumption for own needs for generation of electricity in the system since 2005 is lower compared to the industry. Much lower that in the industry – in average by 10 kWh/Gcal –in the system is the specific electricity consumption for heat supply.

In using the reserve fuel in Tatarstan power system the minimum was reached – since 2000 already the share of fuel oil does not exceed 9%, аnd the share of the coal even lower than 1%. Burning of the coal with the share of over 30% is short in time and takes place at Kazan CHP-2 only during the cold weather in the heating season. In the industry the share of coal burning is much higher. We should mention that when operating on the wholesale electricity market (ORE) increased the number of conversions form one type of fuel to the other, which is connected with frequent limitations of gas supplies during the peak electrical loads, with increased number of the external initiatives of the system operator under conditions of the growing electricity consumption and decrease of the reserve of capacity in total in the industry and in the different regions.

The more optimal loading of the heat generating facilities of the plants in total characterizes the fact that the ration of utilization of the thermal capacity of CHP in Tatenergo is traditionally higher than in the other systems.

Optimization of the plant operation regimes in the company in the last years allows to currently for the company CHP retain the level of specific consumption of the reference fuel for electricity supply at the level of 300 g/kWh, which figure is much lower than the average in the industry.

Among over 50 CHP of the country, working with the equipment 130 ata, only 25 plants have the specific fuel consumption for electricity supply lower than 300 g/kWh. They include the two Tatarstan – Naberezhnye Chelny and Nizhnekamsk CHP. And only the two plants – CHP-21 Mosenergo and Petrozavodsk CHP – in total with regard to cost-efficiency of electricity supply and heat have the higher figures than NabCh CHP.

Specific costs for heat supply lower than 135 kg/Gcal have not more than 25% CHP, including Naberezhnye Chelny CHP, Nizhnekamsk CHP and Kazan CHP-3 JSC of "Generation Company" of Tatarstan power holding. Considering the dynamics of changing the basic EP in the last 3 years regarding the basic parameters of cost-efficiency of generation, the NabChCHP, is one of the best CHP in the industry, having the heat generating equipment with the steam parameters prior to critical. Zainsk GRES ranks third among the GRES’s with the gas-fuel oil units К-200,215-130.
