Operation & Maintenance expenses
1. The O&M expenses for the Base Year, if required, will be used for projecting the expenses for each year of the control period.
2. The Commission will determine the admissible quantum ofO&M exp~nses for each year of the control period on the basis of the following formula:
O&MLo = 0.3*O&Mo / LLo
O&MSo = 0.7*O&Mo / SSo
O&MLn = O&MLn -1*INDX
O&MSn = O&MS n-1 * INDX
O&M = O&MLn *LLn + O&MSn *SSn
Where,
O&MLo is the O&M cost per ckt-km (circuit-kilometers) of EHT (Extra High Tension) lines for the Base Year of the first Control Period
O&MSo is the O&M cost per bay of substations for the Base Year of the first Control Period
O&MLn is O&M cost per ckt-km of EHT lines in nth year
O&MSn is O&M cost per Bay in nth year
LLn is the cumulative length ofEHT lines in ckt-kms in nth year
SS,. is the number of EHT Substation Bays in nth year .
INDX is the Inflation Factor
[clause 12]

Allocation of Annual Transmission Charges
1. The transmission tariff payable by the users of the Transmission system shall be determined in accordance
with the following formula: ·
TR= Net ARR/(12*TCC)
Where,
TR: Transmission Rate in Rs./kW/month
Net ARR: Net ARR, as determined under clause 8.3 of the regulation
TCC: Total Contracted Capacity in kW of the Transmission system by all Long-Term Users
[clause 20.1 ]
with the following formula: ·
TR= Net ARR/(12*TCC)
Where,
TR: Transmission Rate in Rs./kW/month
Net ARR: Net ARR, as determined under clause 8.3 of the regulation
TCC: Total Contracted Capacity in kW of the Transmission system by all Long-Term Users
[clause 20.1 ]
Incentive
1. The transmission losses below the approved range shall earn an incentive and such incentive shall be added to the ARR relating to subsequent Control Period.
2. The Commission from time to time, specify any other performance parameters, including availability of Transmission System, quality targets, et( for which penalty or incentive may be required to be included in the application for ARR: .
