to CEA Operation Norms for Thermal Power Generating Stations
Para 1.1(5) of the operation norms states that specified norms
shall apply to new and unused steam power stations, CCGT generating
stations and diesel engine stations for the entire plant life.
It is clarified that the intent was to discourage use of second
hand power plant.
It is clarified that the norms circulated would apply to both
existing as well as new plants as already brought out in the advertisement
of the Commission.
However, in case of existing power plants where the Net Heat Rate
as per the formula given in para B.1.12 is less than guaranteed Net Heat
Rate multiplied by the appropriate degradation factor (1.05 for Steam
Power Plant, 1.035 for CCGT Generating Stations and 1.0325 for SCGT
Generating Stations), the guaranteed, Net Heat Rate multiplied by the
degradation factor shall apply.
Annual Plant Load Factor of 75% for recovery of capacity charge or fixed
charge specified at par 184.108.40.206.2 shall not apply in view of the
Availability Based Tariff (ABT) Order issued by the Commission on 4th
Further, the term “Availability Factor” may be substituted for
“Deemed Plant Load Factor”.
The calculations of fuel charges shall be for settlement period of 15
minutes for all types of Thermal Power Stations in line with the ABT
order, as per the model calculations enclosed with the norms which takes
into account the actual loading on the units.
