For future plant norms justification can be discussed up-front.
For existing plant :- There is a need to understand Industry as
it exists.- Environment under which it is performing
- Norms shall address enabling provision to pull up performance.While wielding carrot/stick care is needed
as it may danger the Industry.
Salient submission
17
Tariff norms shall cover methodology of Tariff fixation of existing plants considering a) capacity of the plant b) Vintage/Technologyc) Present level of performanced) Level of redundancy/stock of Insurance sparese) Type of fuel.F) Constraints for improvementsg) Possibility of sustenance of the present level of
performance
Salient submission

Should spell the - Principle guiding fixation of base level of performance for
reward/penalty.
Norms shall be dynamic to absorb improvement
in performance as Industry matures. - Hence provision for review/revision
indicating review period
- Shall cover the basic frame structure of Tariff
setting
Fixed/variable components - Pass through components with reasons
Salient submission
19
Merit order dispatch: - Present system considers only the variable cost irrespective of
fixed cost. - Hence power with high fixed and low variable cost gets
dispatched on priority. - Care shall be taken while posting ‘Take or pay commitment for fuel’ in fixed comportment.
- Shall provide for risk mitigation such as for: - Coal - Railways
- Monsoon vagaries
