R&Mn= K*GFA*(INDXn/INDX0)

Where

“K’ is constant (expressed in %) governing the relationship between R&M costs

and Gross Fixed Assets (GFA) and shall be calculated based on the % of R&M to

GFA of the preceding years of the Base Year in the MYT Order after normalising

any abnormal expenses;

‘GFA’ is opening value of the gross fixed asset of the n^th year;

INDXn is the indexation for nth year of control period;

Note 1: For the purpose of estimation, the same INDX n/INDXn-1value shall be used for all years of the

Control Period. However, the Commission will consider the actual values in the INDX n/INDXn-

1^{at the end of each year during the Annual Performance Review exercise and true up the}

employee cost and A&G expenses on account of this variation, for the Control Period;

Note 2: Any variation due to changes recommended by the Pay Commission or wage revision

agreement, etc., will be considered separately by the Commission;

asset is for a part of the year, depreciation shall be charged on a pro-rata basis.

The residual value of assets shall be considered as 10% and depreciation shall be allowed to a maximum

of 90% of the original cost of the asset. Land is not a depreciable asset and its cost shall be

Provided that the salvage value for IT equipment and software shall be considered as NIL

and 100% value of the assets shall be considered depreciable.

The Commission may, in the absence of the Fixed Assets Register, calculate Depreciation (%) arrived

by dividing the Depreciation and the Average Gross Fixed Assets as per the latest available

Audited Accounts of theTransmission Licensee. The Depreciation (%) so arrived shall be

multiplied by the Average GFA approved by the Commission for the relevant Financial Year to

arrive at the Depreciation for that Financial Year.

Appendix-II: Procedure for Calculation of Transmission

System Availability Factor for a Month

1. Transmission System Availability factor for n^th calendar month (TAFM) shall be calculated by the respective

Transmission Licensee, got verified and certified by the SLDC and separately for each AC and HVDC

transmission system and grouped according to sharing of transmission charges. For the purpose of

calculation of TAFM:

(i)

AC transmission lines: Each circuit of AC transmission line shall be considered as one element:

(ii)

Inter-Connecting Transformers (ICTs)/Transformer: Each ICT bank/Transformer (three single

phase transformers together) shall form one element

(iii)

Static VAR Compensator (SVC): SVC along with SVC transformer shall form one element.

(iv)

Bus Reactors/Switchable line reactors: Each Bus Reactors/Switchable line reactors shall be

considered as one element.

(v)

HVDC Bi-pole links: Each pole of HVDC link along with associated equipment at both ends shall be

considered as one element.

(vi)

HVDC back-to-back station: Each block of HVDC back-to-back station shall be considered as one

element. If associated AC line (necessary for transfer of interregional power through HVDC back-

to-back station) is not available, the HVDC back-to-back station block shall also be considered as

unavailable.

(vii)

Static Synchronous Compensation (“STATCOM”): Each STATCOM shall be considered as separate

element

2. The Availability of AC and HVDC portion of Transmission system shall be calculated as under:

% TAFM for AC System

[{(o xAVo)+(p xAVp)+ (q xAVq)+ (r xAVr)+ (u x AVu)} / (o + p + q + r + u)] x 100

Where

Total number of AC lines.

AVo =

Total number of ICTs/Transformer.

3. The availability for each category of transmission elements shall be calculated based on the weighted factor,

total hours under consideration and non-available hours for each element of that category. The calculation

of Availability of each category of the transmission elements are as per Appendix III. The weightage factor

for each category of transmission elements shall be as under:

a. For each circuit of AC line – Number of sub-conductors in the line multiplied by ckt-km;

b. For each HVDC pole – The rated MW capacity x ckt-km

c. For each ICT bank/Transformer – The rated MVA capacity

d. For SVC- The rated MVAR capacity (inductive and capacitive)

e. For Bus Reactor/switchable line reactors – The rated MVAR capacity.

f. For HVDC back-to-back station connecting two Regional grids- Rated MW capacity of each block.

4. The transmission elements under outage due to following reasons shall be deemed to be available:

Jharkhand Gazette (Extraordinary) Wednesday 15^th October, 2025

(a) Shut down availed for maintenance or construction of elements of another transmission

scheme. If the other transmission scheme belongs to the Transmission Licensee, the SLDC may

restrict the deemed availability period to that considered reasonable by him for the work

involved.

(b) Switching off of a transmission line to restrict over voltage and manual tripping of switched

reactors as per the directions of SLDC.

5. Outage time of transmission elements for the following contingencies shall be excluded from the total time

of the element under period of consideration.

(a) Outage of elements due to Force Majeure events such as war, strike, riot, floods, earthquake,

etc., beyond the control of the Transmission Licensee. However, onus of satisfying the SLDC that

element outage was due to aforesaid events and not due to design failure shall rest with the

Transmission Licensee. A reasonable restoration time for the element shall be considered by

SLDC and any additional time taken by the Transmission Licensee for restoration of the element

beyond the reasonable time shall be treated as outage time attributable to the Transmission

Licensee. SLDC may consult the Transmission Licensee or any expert for estimation of

reasonable restoration time. Circuits restored through ERS (Emergency Restoration System)

shall be considered as available.

(b) Outage caused by grid incident/disturbance not attributable to the Transmission Licensee, e.g.

faults in substation or bays owned by other agency causing outage of the Transmission

Licensee’s elements, and tripping of lines, ICTs, etc. due to grid disturbance. However, if the

element is not restored on receipt of direction from SLDC while normalizing the system

following grid incident/disturbance within reasonable time, the element will be considered not

available for the period of outage after issuance of SLDC’s direction for restoration.

6. Time frame for certification of transmission system availability: Following schedule shall be followed for

certification of availability by SLDC:

 Submission of outage data by Transmission Licensees to SLDC- By 5th of the following month;



Review of the outage data by SLDC – By 20th of the month;

 Issue of availability certificate by SLDC- By 3rd of the next Month.
