Transmission services to TANGEDCO, Captive and Open Access (OA) Customers.
2. Submissions of the Petitioner
2.1. The Tamil Nadu Transmission Corporation Ltd. (TANTRANSCO) is engaged
in the transmission of power generated from the generating stations to distribution
centres (under TANGEDCO) with the help of transmission network (GRID). The
transmission network consists of sub-stations and its associated lines of various
voltage levels. Based on the capacity and location of the addition of generation
capacity and quantum and area of demand in the distribution side, augmentation of
transmission system by creating new network and upgrading the existing system, it
is essential to ensure that adequate Transmission System is available with
redundancy. As on 31.03.15, TANTRANSCO was having a Transmission network
comprising 1436 sub-stations of voltage rating 66 kV and above and 28701.31 ckt
kms of EHT lines. During FY 2015-16, 67 Nos. sub-stations with a capacity of 2597
MVA, 1962.839 ckt Kms of EHT Lines and 141 Nos. power transformers with a
capacity of 1852.50 MVA towards additional/enhancement in the existing
substations, have been commissioned.
2.2. The installed generation capacity as on April 1, 2016 was 14,786 MW
including Hydro, Thermal, Gas, Share from CGS, IPP and CPP. The installed
capacity of renewable energy sources was 9,629.52 MW. The addition in generating
capacity has been planned by forecasting the increase in demand for power at
approximately 7% per annum. The capacity addition planned up to FY 2019-20 for

Gummudipoondi area, a 400 kV substation is proposed at Thervaikandigai with
connectivity to the proposed 400 kV Manali substation and 400 kV Korattur substation.
The 400 kV Thervaikandigai substation is back charged at 230 kV level on April 15,
2016. Further, 400 kV line works are under progress and the substation at 400 kV level
is planned to be completed by FY 2016-17.
2.10. The Petitioner submitted that Tamil Nadu, being a pioneer in promoting
Renewable Energy (RE) owing to its huge potential of wind along with other forms of
RE including Solar, has planned its transmission infrastructure to match with the
ambitious RE capacity addition. The estimated RE addition in the next five years will be
around 8,000 MW. The details are as under:
(a) For evacuation of about 3,000 MW wind power in Theni and Udumalpet
districts, three new 400 kV substations at Thappagundu, Anikadavu and
Rasipalayam with associated 400 kV lines of 788 ckt-km are proposed. The
works are under progress for these substations. The 400 kV line from
Thappagundu to Anikadavu and Anikadavu to Rasipalayam has been

2.12. A 400 kV substation at Vellalaviduthi in Pudukkottai district is also proposed for
solar power evacuation and is expected to be commissioned in FY 2018-19.
Considering the already proposed and future expected addition of RE generation in
Tamil Nadu network, the Petitioner has proposed to establish 400 kV substations, viz.,
Samugarengapuram in Tirunelveli area and Ottapidaram in Tuticorin area for
evacuation of wind/solar energy in addition to the private power generation at
Ottapidaram.
2.13. As major portion of the capacity addition of RE generation is proposed near
Kamudhi, Rameshwaram, Thiruchuli and Pudukkottai area, the solar and wind power
generated in Tirunelveli area shall be pooled at Virudunagar 765 kV substation for
transferring to load centres.
2.14. Considering the demand growth rate of 7%, various proposals for establishment
of substations up to 400 kV level are planned and executed. In addition to the projected
load growth, the schemes are designed to ease present congestion and to improve
redundancy to reasonable extent enabling operational flexibility.
2.15. While focussing on Chennai region with its rapidly growing demand, three (3)
nos. of 400 kV substations at Manali, Sholinganallur and Korattur have been proposed
in the periphery of Chennai city. Also, two (2) nos. of substation at Guindy and
Taramani have been proposed in the heart of the city. The works are under progress for
400 kV Manali substation and 400 kV Sholinganallur substation. These substations are

Further, downstream 110 kV substations near distribution load centres are
proposed to reduce the overloading in the existing substations, improve the voltage
regulation, meet the EHT demand, extend 33 kV source to proposed 33 kV substations,
etc. The addition and enhancement of power transformers in the existing substations
are also taken up to ensure optimum loading of the substations, provide adequate
system support for load development in the area and to improve the quality of power
supply.
2.16. The Petitioner added that there will be saving in line loss relatively due to
establishment of substations in the range of 1-4 MW, based on the load flow analysis.
TANTRANSCO is taking all efforts to reduce the transmission losses by constantly
upgrading the existing system, strengthening the existing aged transmission lines with
higher capacity conductors, standardisation of conductor sizes for various voltage levels
with Panther for 110 kV lines, Zebra for 230 kV lines, etc., replacement of old 110 kV
Page 13 of 30
and 230 kV lines with bunched conductors and Dog conductor in a phased manner.
2.17. The Petitioner submitted that the execution of some of the schemes has been
delayed. It is observed that the execution of 400 kV substations at Thappagundu and
Anikadvu, awarded to M/s BHEL, is getting delayed due to slow progress of work by the
contractor. The review meetings at Head Quarters and at field level are being
conducted to sort out the issues and expedite the work.
2.18. Further, 400 kV Sholinganallur (Ottiyambakkam) substation works are near
completion. The 400 kV line work from Kalivanthapattu to Sholinganallur
(Ottiyambakkam) is delayed due to repeated objection by various land owners, with
some of them filing suit in the Hon’ble Supreme Court. The Judgment has been
delivered in favour of TANTRANSCO by Hon’ble Supreme Court and work has
commenced with police protection. In the meanwhile, again case was filed by some
land owners and is being followed up.
2.19. The Petitioner further submitted that even though 400 kV Kanarpatty substation
works have been completed, the commissioning is being delayed due to Right of Way
(RoW) issues in line work. As regards 400 kV line work from Kanarpatty to Kayathar,
the permission was requested from District Collector-Tuticorin due to severe objections
by land owners and the same is still awaited. In another line works from Kanarpatty to
Abishekapatty, the line is aligned through lake area and work could not be taken up for
quite some time due to heavy monsoon rains and water logging. Now, the work has
been completed and the substation has been commissioned on January 9, 2017.
Page 14 of 30
2.20. As regards 400 kV Karamadai substation, 400 kV line work is delayed due to
severe RoW issues, even though substation work has been completed. After close
follow up, line work was completed and the substation has been commissioned on
August 24, 2016. Delays are also being experienced in getting the required details from
District administration for payment of crop compensation. In respect of cable laying
works, work is getting delayed in obtaining permission from Corporation, Public Works
Department, National Highway Authority of India, Police Department, Forest
department, etc.
2.21. In view of the reasons stated above, there are slippages in completion schedule
for transmission schemes. All efforts are taken by TANTRANSCO at field level as well
as at Head Quarters level to resolve the issues and to commission the substations and
lines at the earliest.
2.22. The Petitioner submitted that the funds for financing the various transmission
schemes are being raised from various Financial Institutions such as REC, PFC, Tamil
Nadu Investment Promotion Programme (TNIPP), NABARD, Japan International
Cooperation Agency (JICA), etc. For creation of transmission infrastructure for RE,
financial assistance of 40% Grant under National Clean Energy Fund (NCEF) by
Government of India (GoI), 40% as soft loan from KfW German funding under Indo-
German Bilateral Cooperation, and 20% as equity by TANTRANSCO is approved. For
Transmission Line improvement works, funding is also being tied up with REC/PFC.

hearing, the Petition was admitted, and the Petitioner was directed to file the additional
affidavit detailing the projected demand and generation growth, expected load centre
and generation hubs and transmission schemes required to meet the same including
redundancy for ensuring reliability, improvement of the existing network, reduction in
line loss, etc.

5. TANTRANSCO submitted its additional affidavit with details as directed by the
Commission on 27.06.2016. The Commission, vide Order dated 29.12.2016, directed
TANTRANSCO to upload the Petition on its website to invite comments and
suggestions from the stakeholders.
6. No written comments have been received from any stakeholder on
TANTRANSCO’s CIP Petition. Since, FY 2016-17 is already over, the Commission
asked TANTRANSCO to submit the updated status of capital expenditure incurred and
capitalisation achieved, to facilitate a realistic estimate of capital expenditure and
capitalisation for FY 2016-17 to FY 2018-19. The Commission has analysed the final
proposals for transmission schemes for the Control Period from FY 2016-17 to FY
2018-19.
5. Findings of the Commission:-
5.1. The Commission notes that the Petitioner has submitted the transmission
scheme-wise details for the Control Period from FY 2016-17 to FY 2018-19. The
Petitioner has filed the CIP in accordance with Regulation 17 of the Tariff Regulations.
The transmission schemes include the On-going schemes, which are started prior to
commencement of the Control Period and new schemes, which are going to be started
during the Control Period.
5.2. Since FY 2016-17 is already over, the Commission has considered the revised
phasing of capital expenditure for such schemes based on status submitted by
TANTRANSCO. The Commission has analysed the details submitted by the Petitioner
Page 19 of 30
for each scheme. The Petitioner has submitted the cost of capital works based on the
initially approved cost by the Board of TANTRANSCO. For schemes for which the
approval of Board of TANTRANSCO is awaited, the cost based on the scheme DPR
has been submitted. For the purpose of the approval, the Commission has considered
the cost of the scheme as approved by the Board of TANTRANSCO.
5.3. The Commission in the last Order on approval of CIP had approved the Capital
expenditure only. However, in the present Order, the Commission approves the Capital
expenditure as well as capitalisation based on project cost, phasing and anticipated
completion of the schemes.
5.4. As regards the 765 kV level substation schemes, the Petitioner has proposed
four (4) nos. of 765 kV Substations, viz., Ariyalur, North Chennai Pooling Station,
Coimbatore and Virudhnagar. Out of this, the Board Approval for 765 kV Virudhnagar
Substation is awaited and no capital expenditure for the said scheme was projected.
The Commission accepts the submission of the Petitioner and has not considered the
capital expenditure towards 765 kV Virudhnagar Substation. After taking into account
the present status of other substation works, the Commission has considered the
capital expenditure and capitalisation as submitted by TANTRANSCO.
5.5. As regards 400 kV level substation schemes funded by Japan International
Corporation Agency (JICA), the Petitioner has proposed five (5) nos. of 400 kV
substations, viz., Sholinganallur (Ottiyambakkam), Karamadai, Manali, Korattur and
Guindy. The Commission has considered the scheme-wise capital expenditure based
Page 20 of 30
on the details provided by the Petitioner. The Commission has considered the
scheduled completion of Korattur and Guindy substations in FY 2018-19, and other
substations in FY 2016-17 and FY 2017-18, considering the present progress of the
works. As regards 400 kV level substation schemes funded by sources other than JICA,
the Petitioner has proposed 400 kV substations at various locations, viz.,
Thervaikandigai, Thappagundu, Anikadavu, Rasipalayam, Dharmapuri (Palavady),
Kanarpatty, Pulianthope, Vellalavidudhi (Pudukkottai), Edayarpalayam, Tharamani
(Upgradation) and Kolappalur. Out of these schemes, the Board Approval is awaited for
400 kV Kolappalur substation. The Commission has considered the capital expenditure
required at initial stage of the project, i.e., Rs. 5 Crore in FY 2017-18 and Rs. 50 Crore
in FY 2018-19. For other schemes, the capital expenditure and capitalisation have been
considered based on present progress of the work and anticipated completion
schedule.
5.6. As regards 400 kV transmission lines scheme, the Petitioner has proposed
transmission lines scheme for link lines, power evacuation lines and improvement lines.
The Commission has considered the capital expenditure based on present progress of
the schemes.
5.7. The Commission notes that in the CIP Petition, the Petitioner has submitted
lumpsum provision towards capital expenditure and capitalisation for schemes funded
by JICA and KfW. The Commission sought scheme-wise Capital Expenditure and
Capitalisation against each of the JICA and KfW schemes. After perusing the details of
the project cost, status of the project and the anticipated completion of the project, the
Page 21 of 30
Commission observes that the capitalisation figures are not proportionate to the
progress of work. It is seen that a few schemes under JICA funding that have been
charged/commissioned during 2016-17 have not been capitalised fully in the respective
year. The Commission has considered actual capitalisation of the individual schemes
submitted by the petitioner subsequently for FY 2016-17 and allowed the balance cost
in the subsequent years. Hence, the capitalisation approved by the Commission is
lower for FY 2016-17 and on the higher side for FY 2017-18 as against that proposed
by the Petitioner. Regarding KfW funded schemes, the Commission observes that as
the schemes are under progress, the Petitioner has proposed lower capitalisation for
FY 2017-18 and FY 2018-19 only. The Commission has considered the capitalisation
based on progress of work and hence, the capitalisation approved by the Commission
is higher than the capitalisation proposed by the Petitioner.
5.8. Further, as regards 230 kV Substation schemes, the Commission notes that
Board Approval is yet to be accorded for some of the schemes, hence, the Commission
has considered the capital expenditure for such scheme based on the submissions
made by the Petitioner and status of implementation. As regards the 110 kV substation
schemes, the Commission has considered the ongoing schemes as submitted by the
Petitioner. For the Control Period, the Petitioner has submitted the total expenditure for
40 Nos. of substations. The Commission sought the list of 110 kV substations to be
undertaken during the Control Period along with cost details. Based on this, the
Commission has approved the capital expenditure and capitalisation towards 110 kV
substation schemes. Accordingly, the schemes proposed by the Petitioner and
Commission’s observations have been duly deliberated in Annexure 1. The capital
Page 22 of 30
expenditure and capitalisation has been approved by the Commission considering the
status of the project, scope of work, technical justification, cost of project, etc.
5.9. As regards the execution of the projects, the Commission notes that the
Petitioner has submitted the various issues involved in execution of works such as filing
of case by land owners, ROW issues, permissions from Government Departments, etc.
Regarding the delay in implementation of the schemes, the Commission in Order dated
June 28, 2016 regarding approval of CIP for FY 2014-15 and FY 2015-16 has observed
as under:
“19.1.3 On going through the details of the capital works submitted by
TANTRANSCO, it is seen that there is a huge time gap between initial
approval date of the scheme and taking up of work and award of works.
Also there is again a time over run from award date to completion of the
schemes. For example, Palakkapalayam which has been initially
approved during 2008, was actually completed during 08/2014 only. This
is also observed in most of the 230 kV substation schemes such as
Anthiyur, Guindy, Karamadai, Thingalur, Ulundurpet, Singapuram etc.
Though the Utility is well aware that delayed implementation / completion
of the schemes reflects on the costs, the initiative taken by the Utility to
ensure speedy completion of capital works is far from satisfactory.”
5.10. After going through the details of schemes submitted by the Petitioner, the
Commission has observed huge time gap between the initial approval of scheme and
execution of work in this Petition also. For example, the Board Approval for 400 kV
Sholinganallur (Ottiyambakkam) Substation was accorded on April 11, 2007, however,
the actual work completion date proposed is March 31, 2017. Similarly, Board Approval
for 230 kV Kancheepuram Substation was accorded on June 15, 2011,however, actual
work completion is proposed as March 31, 2017. Likewise, there is a mismatch
Page 23 of 30
between the sub-station works and its associated line works in certain sub-station
schemes i.e either the sub-station works have been completed but line works are under
progress or vice versa.
5.11. Transmission Licensee cites Right of way issues and litigations by contractors on
whom certain works have been awarded as the main reasons for the delay in execution
of the projects. However, we have also noticed that there is lack of coordination and
synchronization in taking up the sub-station works and associated line works, tenders
getting multiple times lodged causing undue delay in taking up approved schemes
contributing to delays. TANTRANSCO with rich experience and expertise in the field
must be able to complete the projects/schemes well within the scheduled time line with
occasional exceptions owing to some unanticipated external factors. We, therefore,
direct TANTRANSCO to take proactive measures to ensure the timely completion of
transmission schemes.
This Commission would also like to point out that the petitioner shall ensure that
each element of the transmission system whenever taken up for construction is
thoroughly analysed and necessity established. Though the Commission is aware that
the investments proposed by TANTRANSCO for establishing 230 kV and 110 kV sub-
stations are primarily to meet the increasing demand, to avoid overloading of the nearby
sub stations, to accommodate future loads and reduce loss, the Utility shall refrain from
proposing and taking up establishment of 110/11 kV sub-stations as a matter of routine
and let the distribution licensee viz. TANGEDCO to propose more 33 kV sub-stations.
This will result in reduction in line losses for both TANTRANSCO and TANGEDCO.
Therefore as a rule TANTRANSCO shall consider 110/11 kV sub-stations only in case
Page 24 of 30
where the 11 kV loads to an extent of not less than 10 MW is consumed within a radius
of say 5 Kms. This rule will be applicable to this order also even though the
Commission has approved all the schemes proposed by the petitioner.
5.12. The Commission, in this Order, has accorded the approval of capital
expenditure for each transmission scheme separately. Hence, for transmission
schemes commencing during the Control Period, i.e., April 1, 2016 onwards, the
Commission directs TANTRANSCO to submit the year-wise actual capital
expenditure incurred along with detailed justification for delay, if any, at time of
approval of actual capital expenditure and capitalisation. Further, the
Commission directs TANTRANSCO to maintain the record for the scheme-wise
actual capital expenditure incurred and actual capitalisation done separately for
the schemes commencing after April, 2016, which shall be submitted to the
Commission at the time of next Tariff Petition. The Commission shall approve the
actual Capital expenditure and actual capitalisation based on such scheme-wise
information, subject to prudence check.
5.13. The Petitioner has submitted the scheme-wise cost benefit analysis and
justification. The Petitioner has submitted the benefits towards the proposed Capital
works such as evacuation of power from renewable sources, reduction in transmission
losses, optimal loading for substation/substation equipment, improvement in voltage
regulation of transmission system, etc.
5.14. The Commission notes that the Act mandates that the primary function of State
Page 25 of 30
Transmission Utility (STU) is to ensure development of an efficient, coordinated and
economical system of intra-State transmission lines for smooth flow of electricity from a
generating station to the load centres and to provide non-discriminatory open access to
its transmission system for use by any Licensee or Generating Company or any
consumer on payment of the Transmission Charges. Also, the Tariff Policy, 2016
stipulates that:-
(a) STU should undertake network expansion after identifying the requirements
in consonance with the National Electricity Plan and in consultation with
stakeholders, and taking up the execution after due regulatory approvals. For
smooth operation of the grid, efforts should be made to develop transmission
system ahead of generation;
(b) STU should ensure upgrading of transmission systems to avoid the situations
of overloading, as the additional flows above a level of line loading lead to
significantly higher losses. The Appropriate Commission should permit
adequate capital investments in new assets for upgrading the transmission
system.
5.15. In the proposed CIP, the Petitioner has proposed the transmission Schemes for
evacuation of power from thermal generating stations and RE sources, network
expansion and system strengthening, establishment of 230/110 kV network primarily to
meet the increasing demand, to avoid overloading of the nearby sub stations, to
accommodate future loads, reduce line loss, etc.
5.16. The Commission appreciates that TANTRANSCO’s primary duty is to establish
and maintain reliable transmission network across the State in order to cater to the
needs of the consumers of the State and to operate its transmission system in the most
economical manner. The Petitioner is required to ensure that each element of the
transmission system whenever taken up for construction is thoroughly analysed using
Page 26 of 30
modern facilities that are available in order to achieve the targeted reliability in an
economic manner.
5.17. As regards the quantification of losses, the Commission in its order dated
28-06-2016 in M.P.No. 54 of 2014 held as follows:-
“19.2.5. … … …
Another important aspect that the Utility shall consider is optimizing the
transmission losses. Optimisation of transmission loss necessarily
involves consideration of cost benefit. It is necessary that whenever a new
transmission scheme is proposed, the utility shall assess the transmission
loss before inclusion of the element and after inclusion of the same.
Similarly whenever a new improvement scheme is proposed, it is very
essential to quantify and compare the reduction in transmission loss that
would result on account of the commissioning of the proposed scheme vis
a vis the cost incurred for setting up the same.”
5.18. Considering the schemes proposed by the Petitioner in the present CIP, the
Commission re-iterates that TANTRANSCO should quantify and compare the reduction
in transmission loss that would result on account of commissioning of the proposed
scheme.
5.19. In view of this, the Commission directs the Petitioner to quantify the
reduction in transmission loss on account of commissioning of scheme and
submit such actual cost benefit analysis to the Commission along with details
such as scope of scheme, methodology adopted for quantification of losses,
reduction in transmission loss, cost incurred for such scheme, etc., after
completion of schemes on annual basis.
5.20. Based on the approval of Capital expenditure and Capitalisation as discussed in
earlier sections of this Order, the summary of the approved CIP is given in the following

Page 28 of 30
5.21. As regards the Capitalisation, many of the Ongoing schemes planned to be
completed by the end of FY 2016-17 have not been completed, hence, the Commission
has considered the capitalisation of such schemes in FY 2017-18. Hence, the approved
quantum of capitalisation for FY 2017-18 is higher than the capitalisation proposed by
the Petitioner.
5.22. The Petitioner has submitted that the funds for financing the various transmission
schemes are being raised from various Financial Institutions such as REC, PFC, Tamil
Nadu Investment Promotion Programme (TNIPP), NABARD, etc. JICA funding was
approved to the extent of Rs. 3572.93 Crore with an interest rate of 0.5% per annum.
Further, for creation of transmission infrastructure for RE worth Rs. 1593 Crore,
financial assistance of 40% Grant under National Clean Energy Fund (NCEF) by
Government of India (GoI) for Rs. 637.20 Crore, 40% as soft loan for Rs 637.20 Crore
from KfW German funding under Indo-German Bilateral Cooperation, and 20% as
equity by TANTRANSCO of Rs. 318.60 Crore is approved. For Transmission Line
improvement works, funding is also being tied up with REC/PFC.
5.23. The Commission notes that the Petitioner has submitted the funding source for
each scheme. As regards the schemes financed by REC/PFC, the Commission has
considered debt:equity in the ratio of 90:10. Also, in case of schemes financed by
NABARD, the debt:equity ratio has been considered as 80:20. For schemes for which
funding is yet to be tied up, the Commission has considered the funding in normative
debt:equity ratio of 70:30. As regards the scheme financed by JICA, the Commission
has considered 100% loan against such schemes. For the schemes financed under
Page 29 of 30
TNIPP, grant has been considered at 80% of amount of capital expenditure and
remaining amount of capital expenditure is considered to be funded through equity. As
regards KfW schemes, the Commission has considered 40% of amount of capital
expenditure as grant and loan each and remaining amount of capital expenditure is
considered to be funded through equity.
5.24. It is noted that there might be a situation where the Petitioner may receive the
grant for particular scheme upfront during the starting year of the scheme. However, in
the present Order, the Commission has considered the funding for capital expenditure
from grant, loan and equity in the same proportion. The Commission directs the
Petitioner to submit the actual source-wise funding for each transmission
scheme approved in this Order during the next Petition. The Commission shall
approve the actual funding of capital expenditure and capitalisation, after
prudence check.
5.25. The funding of capital expenditure approved by the Commission is shown in the
following Table:

5.26. In the light of the above, we issue the following directions:-
(a) For transmission schemes commencing during the Control Period from April
1, 2016, TANTRANSCO shall submit the year-wise actual capital expenditure
incurred along with detailed justification for delay, if any, at the time of
approval of actual capital expenditure and capitalisation.
(b) TANTRANSCO shall maintain the record for the scheme-wise actual capital
expenditure incurred and actual capitalisation done separately for the
schemes commencing after April, 2016, which shall be submitted to the
Commission at the time of next Tariff Petition. The Commission will approve
the actual Capital expenditure and actual capitalisation based on such
information, subject to prudence check.
(c) The Petitioner is directed to quantify the reduction in transmission loss on
account of commissioning of scheme and submit such cost benefit analysis
to the Commission along with details such as scope of scheme, methodology
adopted for quantification of losses, reduction in transmission loss, cost
incurred for such scheme, etc. after completion of schemes on annual basis.
(d) The Petitioner shall submit the actual source-wise funding for each
transmission scheme approved in this Order along with the next Tariff
Petition. The Commission will approve the actual funding of capital
expenditure and capitalisation, after prudence check.
