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

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

completed. Further, 400 kV line from Rasipalayam to 400 kV Dharmapuri

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

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.

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.

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

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

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

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

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

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

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

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

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

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

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.
