State of Tamilnadu - Section

Section 37 in Tamil Nadu Electricity Regulatory Commission (Terms and Conditions for Determination of Tariff) Regulations, 2005

37. Norms of Operation.

- The norms of operation for the Thermal Generating Stations shall be as under:
(i)Target availability for recovery of full capacity (fixed) charges
(a)All Thermal Generating stations in Tamil Nadu except Ennore Thermal Power Generating Station 80%
(b)Ennore Thermal Power Generating Station 50%
(Till Renovation and Modernization works in all units are completed) (c) In respect of Generating Stations of.... As per PPAIndependent Power Producers
(d)New Thermal Stations
(ii)Target Plant Load Factor for incentive
(a)All the Thermal Power Generating Stations except the existing Stations of Independent Power Producers covered under Power Purchase Agreements 80%
(b)Power Generating Stations of Independent Power Producers covered under 80% existing Power Purchase Agreement
(iii)Gross Station Heat Rate As per PPA
(a)"Norms for the existing Coal-based Thermal Power Generating Stations
Station Heat Rate
1. ETPS 3200 kcal/kwh
2. TTPS 2453 "
3. MTPS 2500 "
4. NCTPS 2393 "
(b)Norms for the new Thermal Power Generating Stations 200/210/250 MW sets 500 MW and above sets
During Stabilisation period 2600 KCal/kWh 2500 KCal/kWh Subsequent period 2550 Kcal/kWh 2450 Kcal/kWhNote-1 : In respect of 500 MW and above units where the boiler feed pumps are electrically operated, the heat rate of 40 kCal/kWh shall be reduced from the Generating Station heat rate indicated above.Note-2 : For Generating Stations having combination of 200/210/250 MW sets and 500 MW and above sets, the normative gross Generating Station heat rate shall be the weighted average Generating Station heat rate of various sets.
(c)Lignite-fired thermal power Generating Stations
The station heat rate specified in clause (b) above for coal based Thermal Power Generating Station shall be corrected, using multiplying factors as given below:
(i)For lignite having 50% moisture: Multiplying factor of 1.10
(ii)For lignite having 40% moisture: Multiplying factor of 1.07
(iii)For lignite having 30% moisture: Multiplying factor of 1.04
(iv)For other values of moisture content, multiplying factor shall be pro-rated for moisture content between 30-40 and 40-50 depending upon the rated values of multiplying factor for the respective range given under sub-clauses (I) to (iii) above.
(d)Gas-Turbine / combined cycle Generating Stations Advanced class E/EA/EC/E2 class machine machine
Open Cycle 2685 Kcal/kWh 1850 Kcal/kWhCombined cycle 2830 Kcal/kWh 1950 Kcal/kWh
(iv)Secondary fuel oil consumption

The auxiliary consumption norms shall be 0.50 percentage point more than the auxiliary energy consumption norms for coal based Generating Stations indicated in a (i) and (ii) above.
(d)During stabilization period, normative auxiliary consumption shall be reckoned at 0.50 percentage point more than the norms indicated at (a), (b) and (c) above.
(vi)Stabilization period r
The stabilization period of a unit shall be reckoned commencing from the date of commercial operation of that unit as follows:
(a)coal-based and lignite-fired Generating Stations -180 days
(b)Gas turbine / combined Generating Stations - 90 days
