Norms of operation
(a) For recovery of Annual Fixed Cost, NATAF shall be as under:
(1) AC system: 98.00%;
(2) HVDC bi-pole links 95.00% and HVDC back-to-back stations: 95.00%:
Provided that the normative annual transmission availability factor of the
HVDC bi-pole links shall be 85%for first twelve months from the date of
commercial operation.
b) For Incentive, NATAF shall be as under:
(1) AC system: 98.50%;
(2) HVDC bi-pole links and HVDC back-to-back Stations: 97.50%:
Provided that no Incentive shall be payable for availability beyond 99.75%:
Payment of Transmission Charges
The Transmission charge (inclusive of incentive) payable for a calendar month for
transmission system or part shall be computed for each region separately for AC and
DC system as under:
For AC system:
a) For TAFM n< 98.00%
AFC x (NDMn/NDY) x (TAFMn/98.00%)
b) For TAFMn: 98.00%< TAFMn< 98.50%
AFC x (NDMn/NDY) x (1)
c) For TAFMn: 98.50%< TAFMn< 99.75%
AFC x (NDMn/NDY) x (TAFM/98.50%)
d) For TAFMn> 99.75%
AFC x (NDMn/NDY) x (99.75%/98.50%)

For HVDC bi-pole links and HVDC back-to-back Stations:
TC1 = AFC x (NDM1 / NDY) x (TAFM1/NATAF)
TC2 = AFC x (NDM2 / NDY) x (TAFM2/NATAF) – TC1
TC3 = AFC x (NDM3 / NDY) x (TAFM3/NATAF) – (TC1+TC2)
TC4 = AFC x (NDM4 / NDY) x (TAFM4/NATAF) – (TC1+TC2+TC3)
….
TC11 = AFC x (NDM11/NDY) x (TAFM11/NATAF) - (TC1+TC2+….+TC10)
TC12 = AFC x (TAFY/NATAF) – (TC1+TC2+….+TC11);

If,
(i) TAFM: 95.00%< TAFM < 97.50%, then TAFM=NATAF;
(ii) TAFM: 97.50%< TAFM < 99.75%, then NATAF=97.50%; and
(iii) For TAFM > 99.75%, then TAFM=99.75% and NATAF= 97.50%.

Where,
TCn = Transmission charges inclusive of incentive up to the nth month
AFC = Annual fixed cost specified for the year in rupees
NATAF = Normative Annual Transmission Availability Factor in percentage
NDMn= No of days upto the end of nth month of the financial year
NDY = No. of days in the year
TAFMn= Transmission availability factor upto the end of the nth month of the year
in percentage
TAFY = Transmission availability factor in percent for the year.
