5. Generation Parameters Projection

5.1. Generation Projection

The Petitioner has existing generation facility of 420 MW (2x210 MW) coal based thermal power plant at Bokaro. Petitioner is making all efforts to improve the generation and has significantly targeted higher generation for FY 11.
 

Table 7: Generation Parameters Projection (MU)

5.2. Plant Load Factor (PLF)

A PLF of 74.88% is being projected for the plant in FY11.

Table 8: Projected Generation Performance for FY11

5.3. Auxiliary Consumption

The auxiliary consumption is specific to a particular power station and depends on its configuration, age and related technical parameters. Auxiliary power is required for different equipments like feed pumps, cooling water pumps, air fans, coal grinding mills, ash handling equipments, common auxiliaries etc. of the generating station. The auxiliary consumption was 9% in FY 2010 Petitioner projects its auxiliary consumption at 9% for FY 11.

Table 9: Auxiliary Consumption for FY’11

5.4. Heat Rate

Petitioner is increasing its efforts to reduce the heat rate and hence has targeted a stiffer target of 3000 kCal/kWh for 2010-11.

Table 10: Projected Heat Rate for FY’11

5.5. Specific Coal Consumption

The Petitioner sources D grade coal from the collieries of Central Coal Fields Limited with calorific value of about 4300 kCal/kg.

Table 11: Specific Coal Consumption

Petitioner in line with an aim for achieving better operation targets to achieve specific coal consumption of 0.7 kg/kWh.

5.6. Secondary Fuel Consumption

Due to the large number of outages experienced by the station due to transmission line trippings etc., the Petitioner was not been able to achieve the norm of 2 ml/kWh fixed by the Honourable Commission for specific oil consumption.

The Petitioner observed a specific oil consumption of 3.296 ml/kWh during FY 2009-10. Petitioner is planning to reduce its oil consumption and improve the specific oil consumption figure. Petitioner projects a specific oil consumption of 2.5 ml/kWh.

5.7. Summary

The Petitioner projects the following for 2010-11:
