Rs.2275 crs., DDUGJY schemes for about Rs.165.51 crs. and other completed works
in distribution side for Rs.1800 crs.
3. AT&C Losses
The Petitioner has submitted that T&D losses are due to energy dissipated in
the conductors and equipment used for transmission, transformation, sub-transmission
and distribution of power. These technical losses are inherent in the system and can
be reduced to an optimum level. However, the Commercial losses are due to illegal
consumption of electrical energy, which is not correctly metered and billed, and
causes losses to the utility. The Petitioner further submitted that it has taken various
efforts for reduction of Aggregate Technical & Commercial (AT&C) losses. AT&C
losses have been reduced from 18.40% in FY 2012-13 to 17.96% in FY 2015-16. The
collection efficiency of 98.79% has been achieved in FY 2015-16. The Petitioner has
proposed the works under R-APDRP, IPDS and DDUGJY for reduction of AT&C
losses.
4. Relevant Policy/Regulations
The CIP submitted by TANGEDCO has to be approved as per the relevant
provision of Tariff Policy, Tariff Regulations and MYT Regulations.

the Appropriate Commission. Appropriate capital costs required for pre-determined
efficiency gains and/or for sustenance of high level performance would need to be
assessed by the Appropriate Commission. ……” (emphasis added)
4.2. Regulation 17 of the TNERC (Terms and Conditions for determination of Tariff)
Regulations, 2005 (hereinafter called Tariff Regulations, 2005) specifies as under:
“17. Capital Investment Plan
(1) The licensee shall file a detailed Capital Investment Plan every year showing
separately, ongoing projects that will spill into the year under review and new project
(along with justification) that will commence but may be completed within or beyond
the tariff period.
(2) The Commission may consider the licensee’s investment plan for approval and for
this purpose, may require the licensees to provide relevant technical and commercial
details. The costs corresponding to the approved investment plan of a licensee for a
given year shall normally be considered for its revenue requirement.
(3) In presenting the justification for new projects, the licensee shall detail the specific
nature of the works and the results to be achieved. The details must be shown in
physical parameter (e.g.) new capacity to be added, length of lines to be energised,
number of sub-stations / Bays to be added, meters to be added, replaced, etc. so that it
is amenable for physical verification. In case of significant shortfall in achieving
physical targets, the Commission may require the licensee to explain the reasons, and
may proportionately reduce the provision, including interest and return component
made towards revenue requirement, in the next tariff proposal.
(4) The licensee may, at any time, during the tariff year, seek provision for additional
capital expenditure to meet natural calamities involving substantial investment and the
Commission shall examine and review these provisions in the manner as given in this
regulation and approve their inclusion in the revenue requirement in the next period.
(5) The licensee shall get the Capital Investment Plan approved by the Commission
before filing ARR and Application for determination of tariff.”
4.3. Regulation 3 (v) of TNERC (Terms and conditions for determination of Tariff for

4.4. Further, the Hon’ble APTEL in its Judgment dated October 18, 2014 in Appeal
No. 196 of 2013 filed by M/s. OPG Renewable Energy against the Tariff Order 1 of
2013 had given certain directions regarding the approval of CIP of TANGEDCO for FY
2014-15 and FY 2015-16. After taking cognizance of such directions, the Commission
in the Suo-motu Tariff Order dated December 11, 2014 directed TANGEDCO as
under:
“7: SUMMARY OF DIRECTIVES
7.1 The Commission directs TANGEDCO
a) … … …
b) … … …
c) The Commission likes to reiterate that TANGEDCO shall submit a well-structured
cohesive business plan and detailed individual schemes for the planned capacity
additions as well as system strengthening plans. All such plans and schemes shall be
submitted to the Commission in accordance with the Terms and Conditions of Tariff
Regulations 2005 and its amendment dated 09.04.2014, MYT Tariff Regulations 2009,
as well as Licensing Regulations 2005. The submission for approval in this regard so
far has been highly unsatisfactory. The Commission has been addressing the utilities by
way of letters as well as by way of directions. The compliance to such letters and
directions will have to be serious and without fail.”
4.5. TANGEDCO filed its CIP for FY 2014-15 and FY 2015-16 for approval of the
Commission through additional affidavits dated April 4, 2014, June 2, 2016 and
August 23, 2016 in M. P. No. 39 of 2012. After due verification and scrutiny of the
Petition, the Commission vide Order dated January 31, 2017 approved the CIP for
TANGEDCO for FY 2014-15 and FY 2015-16.

5. Procedure adopted:-
5.1. TANGEDCO has submitted its Petition for approval of CIP for Third Control
Period from FY 2016-17 to FY 2018-19 on November 21, 2016, which was admitted
by the Commission and registered as M.P. No. 28 of 2016. The Commission held a
preliminary hearing in the matter on December 9, 2016. During the hearing,
TANGEDCO was directed to re-submit the CIP Petition with details such as projected
demand, generation capacity addition, distribution load centres, energy loss trajectory,
etc., and schemes for the same.
5.2. The Commission vide Order dated December 29, 2016, directed TANGEDCO
to upload the Petition on its website for obtaining comments and suggestions from the
stake holders and file their reply thereafter along with the compilation of comments
and suggestions. TANGEDCO submitted its revised Capital Investment Plan on
January 5, 2017 with details such as projected demand, generation capacity addition,
distribution load centres, energy loss trajectory, etc., and the respective schemes for
the same. The revised CIP was also uploaded by TANGEDCO on its website on
January 5, 2017. The comments and suggestions provided by the stakeholders in
writing have been summarised issue-wise, along with TANGEDCO’s replies as
elaborated in Appendix of this Order.
5.3. Since, FY 2016-17 is already over, the Commission asked TANGEDCO 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 the generation
and distribution functions for the Control Period from FY 2016-17 to FY 2018-19.
![Page 14: TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Central … order/2017/CIP Order.pdf · 2017-08-02 · Page 1 of 52 TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Constituted under section](https://reader034.vdocument.in/reader034/viewer/2022042803/5f4e321c72a3781dfe6abe40/html5/thumbnails/14.jpg)
Page 14 of 52
6. Findings of the Commission:-
6.1. The Demand and Energy projections made by TANGEDCO depicts deficit
scenario till the end of FY 2018-19. There would be surplus scenario after FY 2019-20
after taking into account the planned capacity addition from FY 2016-17 onwards. The
Commission is of the view that any slippage in the timelines for capacity addition may
lead to continued deficit scenario beyond the Control Period, if the demand increases
as per the projections which may have to be bridged through short term power
procurement.
6.2. While analysing the CIP, the Commission has taken into account the demand
and energy availability projections submitted by TANGEDCO. The Commission has
also taken into account the Stakeholders’ comments and TANGEDCO’s reply while
proceeding with CIP approval.
6.3. The Commission observes that many of the existing thermal stations viz. TTPS
Unit 1, II, III and MTPS Stage I have exceeded their life period and hence,
TANGEDCO has taken up Upgradation of the existing system, Renovation and
Modernisation, capital overhaul works, etc., to ensure availability of these low-cost
power plants. The Hydro stations are very old stations and some of them are in
service since as early as 1940s and the allocation of capital expenditure is largely
towards Renovation, Modernisation and Upgradation (RMU) works, other
modernization works, etc. The proposed capital expenditure for Gas stations is largely
towards statutory inspection that are to be carried out as per the recommendations of
Original Equipment Manufacturer (OEM).
![Page 15: TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Central … order/2017/CIP Order.pdf · 2017-08-02 · Page 1 of 52 TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Constituted under section](https://reader034.vdocument.in/reader034/viewer/2022042803/5f4e321c72a3781dfe6abe40/html5/thumbnails/15.jpg)
Page 15 of 52
6.4. The Commission has taken into account this aspect while approving the capital
expenditure for these schemes. The Commission has considered the capital
expenditure scheme towards Generation Stations/Units, which have surpassed their
useful life or are going to surpass their useful life during the Control Period from FY
2016-17 to FY 2018-19. As regards the existing Generating Stations, the Commission
notes that North Chennai Thermal Power Station-Stage I & II, Mettur Thermal Power
Station Stage -II will not surpass its useful life by the end of the Control Period. Hence,
for such Thermal Generating Stations, the Commission has considered only those
schemes, which are essential for their operation and which qualify under Regulation
19 of the Tariff Regulations.
6.5. Further, the Petitioner has proposed some schemes in FY 2016-17. Since FY
2016-17 is already over, the Commission sought the status of the schemes proposed
in FY 2016-17 from TANGEDCO and has accordingly considered the revised phasing
of capital expenditure for such schemes.
6.6. The Commission has not considered any capital expenditure and capitalisation
towards Ennore Thermal Power Station as the station is de-commissioned. As regards
the existing Thermal Power Station, the Commission has considered the schemes
towards Capital overhauling, replacement of economiser coil, commissioning of
Pressure Reducing De-superheating system, retrofitting of condenser, installation of
fire protection system, replacement of HP module assembly, replacement of IP/LP/HP
rotor, replacement of water wall tubes, revamping of internal coal handling,
replacement of electrical equipments, provision of wireless CCTV and surveillance
![Page 16: TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Central … order/2017/CIP Order.pdf · 2017-08-02 · Page 1 of 52 TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Constituted under section](https://reader034.vdocument.in/reader034/viewer/2022042803/5f4e321c72a3781dfe6abe40/html5/thumbnails/16.jpg)

system, PAT schemes, civil works for ash dyke area, revamping of PDFAC system,
schemes for fulfilment of norms of Pollution Control Board, etc.
The petitioner shall also consider to phase out the old units which have
completed their life period by new high efficiency machines meeting new
environmental norms/policy of GoI.
6.7. As regards Hydro projects, the Commission has considered major capital
expenditure schemes towards Static excitation provision for Kundah Power house-2,
230/22 kV substation at Kundah Power House, RMU of Moyar Power house, Periyar
Power house, Kodayar Power house and Sholayar Power house, replacement of auto
sequencer panel at Kadamparai pumped storage Power house, supplying of barrage
gates at BPH-2, etc.
6.8. As regards Gas Stations, the Commission has considered the major capital
expenditure schemes towards installation of Gas booster, upgradation of equipment
as per OEM recommendations, commissioning of air cooled condenser, construction
of quarters, compressor discharge and turbine casing, etc.
Further, in respect to the capital expenditure proposed for Thirumakottai Gas
Thermal Station, which has completed its life period, the expenditure has been
admitted by the Commission under renovation and modernisation and life extension
programme as per Regulation 19 of Tariff Regulations, 2005. The petitioner is also
directed to submit a comprehensive Plan for Renovation & Modernisation and life
extension for its each of the gas stations as and when they complete their life period
for admitting the expenditure.
6.9. While admitting and approving the capital expenditure for existing Generating
![Page 17: TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Central … order/2017/CIP Order.pdf · 2017-08-02 · Page 1 of 52 TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Constituted under section](https://reader034.vdocument.in/reader034/viewer/2022042803/5f4e321c72a3781dfe6abe40/html5/thumbnails/17.jpg)
Page 17 of 52
Stations, the Commission has been guided by the provisions of the TNERC’s Tariff
Regulations 2005 and MYT Regulations, 2009 reproduced above.
6.10. Accordingly, the schemes proposed by the Petitioner for each of the above
existing Thermal, Hydro and Gas stations and the Commission’s approval of capital
expenditure and capitalisation considering the life period served by the asset
observations have been duly deliberated upon in Annexures 1 to 13.
6.11. For the investment proposals in the existing generating stations
commencing during the Control Period, i.e., April 1, 2016 onwards, the
Commission directs TANGEDCO 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 the Petitioner to maintain the record for the scheme-wise
actual capital expenditure incurred and actual capitalisation done after April
2016 for each Generating Station separately and submit the same to the
Commission at the time of next Tariff Petition. The Commission will approve the
actual Capital expenditure and actual capitalisation based on such scheme-wise
information, subject to prudence check.
6.12. TANGEDCO has submitted that it has prepared the CIP for FY 2016-17 to FY
2018-19 based on the demand and energy availability projections for FY 2016-17 to
FY 2020-21 as per 19th Electric Power Survey (EPS) Projections. Accordingly, for
meeting the additional demand, it has proposed commissioning of new projects, for
which the capital expenditure has been proposed in the CIP.
![Page 18: TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Central … order/2017/CIP Order.pdf · 2017-08-02 · Page 1 of 52 TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Constituted under section](https://reader034.vdocument.in/reader034/viewer/2022042803/5f4e321c72a3781dfe6abe40/html5/thumbnails/18.jpg)

6.13. The new Thermal and Hydro projects are as follows:
Thermal Projects – Ennore SEZ, ETPS Expansion, ETPS Replacement, Uppur
Thermal Project, North Chennai Thermal Power Project Stage III, Udangudi Stage I, II
& III, Kadaladi Super critical Project
Hydro Projects – Mettur Pumped Storage, Modified Moyar Ultimate Stage Phase I,
Kundah Pumped HEP, Sillahalla HEP, Kolli Hydro Project.
6.14. For admitting and approving the capital expenditure for the new Generation
Thermal and Hydro Projects, the Commission is guided by the provisions of
Regulation 6 (7) (i) (a) of the TNERC (Terms and Conditions for the determination of
the Tariff) Regulations,2005 which specifies as under:
“… … …
(7) In case of Generating Station or the Transmission system declared under
commercial operation on or after the date of notification of these Regulations, an
application for fixation of tariff shall be made in two stages as below:
(i) (a) A generation company or a licensee may make an application as per Appendix –
I to these regulations, for determination of provisional tariff in advance of the
anticipated date of completion of the project, based on the capital expenditure
actually incurred upto the date of making of the application or a date prior to making
of the application, duly audited and certified by the statutory auditors, and the
provisional tariff shall be charged from the date of commercial operation of the
respective units of the generation station or the line or sub-station of the transmission
system.
(b) Provisional tariff or provisional billing of charge, wherever allowed by the
Commission based on the application made by the generating company or the
transmission licensee or by the Commission on its own or otherwise, shall be adjusted
against the final tariff approved by the Commission:
Provided that where the provisional tariff charged exceeds the final tariff approved by
the Commission under these regulations, the generating company or the transmission
licensee, as the case may be, shall pay simple interest @ 6% per annum computed on
monthly basis, on the excess amount so charged from the date of payment of such
excess amount and upto the date of adjustment:
![Page 19: TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Central … order/2017/CIP Order.pdf · 2017-08-02 · Page 1 of 52 TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Constituted under section](https://reader034.vdocument.in/reader034/viewer/2022042803/5f4e321c72a3781dfe6abe40/html5/thumbnails/19.jpg)
Page 19 of 52
Provided further that where the provisional tariff charged is less than the final tariff
approved by the Commission, the beneficiaries shall pay simple interest at 6% per
annum, computed on monthly basis on the deficit amount from the date on which final
tariff will be applicable upto the date of billing of such deficit amount.
Provided also that excess/deficit amount along with simple interest at 6% shall be
adjusted within three months from the date of order failing which the defaulting
licensee / beneficiary shall be liable to pay penal interest on excess / deficit amount at
the rate as may be decided by the Commission].
(ii) A licensee shall make a fresh application in the same format as above, for the
determination of final tariff based on actual capital expenditure incurred upto the
date of commercial operation of the Generating Station or Transmission system duly
audited and certified by the Statutory Auditors.
(8). In case the licensee does not initiate tariff filings in time, the Commission shall
initiate tariff determination and regulatory scrutiny on suo motu basis.”
6.15. The above-said Regulations clearly specify that the Petitioner shall approach
the Commission for provisional tariff for new generating stations before the anticipated
date of COD based on capital expenditure actually incurred, duly audited and certified
by the Statutory Auditor. Also, after the achievement of COD of the project, the
Petitioner is required to approach the Commission for approval of capital cost and final
tariff based on actual capital expenditure incurred till COD, duly audited and certified
by the Statutory Auditor.
6.16. In view of the above Regulations, the Commission is of the opinion that it would
not be appropriate to allow the recovery of capital expenditure incurred by the
Petitioner towards new Generating Stations through tariff, without verifying prudency
of the actual capital expenditure incurred before COD of the project. At the same time,
it does not mean that the Commission has rejected the proposed capital expenditure
against these Projects. TANGEDCO is required to ensure that the new generation
projects are taken up on time, based on the projected demand-supply gap/surplus for
![Page 20: TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Central … order/2017/CIP Order.pdf · 2017-08-02 · Page 1 of 52 TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Constituted under section](https://reader034.vdocument.in/reader034/viewer/2022042803/5f4e321c72a3781dfe6abe40/html5/thumbnails/20.jpg)
Page 20 of 52
the future years and to ensure that the cost is optimised.
6.17. In light of the foregoing, the Commission in-principle approves the Capital
expenditure and funding of the new Generation projects as proposed by the
Petitioner. However, the Commission has not considered any capital
expenditure for these projects for recovery through tariff. The Petitioner shall
adhere to the original time lines for the completion of the projects as mentioned
in Detailed Project Report and duly approved by Board of Directors.
6.18. The Commission further directs the Petitioner to file the Petitions for
approval of provisional tariff and final tariff for new Generation projects in line
with the provisions of the Tariff Regulations. The Commission will take a final
view on the time overrun and related cost overrun and IDC component for
individual projects, after the new generation projects are commissioned, and the
actual audited capital cost including IDC are submitted to the Commission with
due justification for the increase in capital cost, if any.
6.19. The Petitioner has proposed capital expenditure for the following thermal and
hydro projects under New Generation projects for which COD has been achieved
earlier:
Thermal Projects (a) Mettur Stage III – COD achieved on 12.10.2013 (b) NCTPS Stage II - COD achieved for Unit 1 – 20.03.2014 and Unit II- 08.05.2014 Hydro Projects (a) Periyar Vaigai IV – COD achieved during Feb’2016 (b) Bhavani Kattalai Barrage I – COD achieved during 2006-07
![Page 21: TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Central … order/2017/CIP Order.pdf · 2017-08-02 · Page 1 of 52 TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Constituted under section](https://reader034.vdocument.in/reader034/viewer/2022042803/5f4e321c72a3781dfe6abe40/html5/thumbnails/21.jpg)

(c) Bhavani Kattalai Barrage II – COD achieved for Unit 1-10.10.2011 & Unit 2 –14.10.2011
(d) Bhavani Kattalai Barrage III – COD achieved for Unit 1- 28.11.2012 & Unit 2 – 28.12.2012 (e) Bhavani Barrage I – COD achieved for Unit 1 – 29.05.2015 &
Unit 2 – 02.07.2015 (f) Bhavani Barrage II – COD achieved for Unit 1 & 2 -15.08.2013
6.20. The directions of the Commission in respect of new generating stations in the
Tariff Order dated June 20, 2013 on Determination of tariff for generation and
distribution is relevant here, and the same is reproduced below:
“3.124 The Commission observed that there are number of new generating stations for which
TANGEDCO had neither sought prior approval of their capital investment plan nor applied for
determination of tariff in advance for the new generating stations.
3.125 TANGEDCO is required to file separate Petitions for approval of the tariff for the new
generating stations along with accounts for these generating stations duly certified by statutory
auditor. On Commission’s directive, TANGEDCO has submitted partial information for new
thermal stations as per the formats prescribed by TNERC Tariff Regulations. However, the
information is not certified by statutory auditor. With respect to new hydro stations
TANGEDCO has not provided any information.
3.126 Regulation 6 (7) (i) (a) of the TNERC Tariff Regulations, 2005 specifies the following:
“A generation company or a licensee may make an application as per Appendix – I to these
Regulations, for determination of provisional tariff in advance of the anticipated date of
completion of the project, based on the capital expenditure actually incurred upto the date of
making of the application or a date prior to making of the application, duly audited and
certified by the statutory auditors, and the provisional tariff shall be charged from the date of
commercial operation of the respective units of the generation station or the line or sub-station
of the transmission system.”
3.127 Hence, the Commission directs TANGEDCO to file the separate petitions based on
TNERC Regulations, within 90 days of issuance of this Order. In failure of this compliance,
Commission may approve the capital cost based on industry norms and may disallow all
expenses allowed due to provisionally approved capital cost in its next tariff order.”
![Page 22: TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Central … order/2017/CIP Order.pdf · 2017-08-02 · Page 1 of 52 TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Constituted under section](https://reader034.vdocument.in/reader034/viewer/2022042803/5f4e321c72a3781dfe6abe40/html5/thumbnails/22.jpg)
Page 22 of 52
6.21. As per the above directions, the Petitioner has filed separate Petitions for
approval of the Capital Cost of NCTPS Stage II Unit I & II and MTPS Stage III in
M.A.P. Nos. 1, 2 and 3 of 2015 and for Periyar Vaigai I, Periyar Vaigai II, Bhavani
Barrage II and Bhavani Kattalai Barrage II in M.A.P. Nos. 1, 2, 3 and 4 of 2014. For
rest of the hydro projects, though COD has been achieved, separate Petitions are yet
to be filed.
6.22. For allowing the capital expenditure of such thermal and hydro projects for
which COD have been achieved and separate Petitions have also been filed for
capital cost approval, the orders of the Commission in the respective Petitions wherein
capital cost for such project were approved by the Commission need to be taken into
account. The observations of the Commission in this regard are detailed below:
I Thermal Projects
The thermal projects, viz., North Chennai Stage II Unit I & Unit II and Mettur
Stage III have been completed with time over-run and cost over-run thereby leading to
increase in the project cost by way of Interest During Construction, Fuel cost, etc. The
quantum of delay and the consequent closure of contract is yet to be taken up. The
Commission, therefore, in its order dated 29.12.2016 in M.A.P No. 1 of 2015,
M.A.P.No.2 of 2015 and in its Order dated 31.01.2017 in M.A.P. No 3 of 2015 of the
respective projects, after prudence check of the actual expenditure incurred by the
Petitioner, disallowed certain portion of the interest expenses and fuel expenses due
to delayed completion of the project and accordingly allowed the cost as on COD
provisionally. The Commission has also directed the Petitioner to file the Petition for
approval of final capital cost based on completed actual capital cost duly certified by
![Page 23: TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Central … order/2017/CIP Order.pdf · 2017-08-02 · Page 1 of 52 TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Constituted under section](https://reader034.vdocument.in/reader034/viewer/2022042803/5f4e321c72a3781dfe6abe40/html5/thumbnails/23.jpg)
Page 23 of 52
Auditors based on Audited Accounts of the project on finalization of the quantum of
Liquidated Damages and other penalties and closure of contract for admitting the
expenditure incurred beyond the COD of the project. Therefore, the capex allocation
for the said projects of NCTPS Stage Unit I & II and MTPS Stage III for the MYT
Control Period from FY 2016-17 to FY 2018-19 are not considered for the present.
II Hydro Projects
(a) With regard to Hydro projects, viz., Bhavani Kattalai Barrage II and Bhavani
Barrage II, which have achieved COD during FY 2011-12 and FY 2013-14,
respectively, and separate Petitions filed for approval of the capital cost under
M.A.P.Nos. 3 and 4 of 2014, the Commission has already restricted the capital
expenditure incurred by the Petitioner upto COD towards project work and IDC in line
with the norms stipulated by CERC in the CERC RE Tariff Regulations in view of the
cost overrun of the project and disallowed the expenditure incurred by the petitioner
beyond COD. However, the Capex allocation for the MYT Control Period from FY
2016-17 to FY 2018-19 are towards compensation value towards land acquired,
construction of protection wall, construction of boundary wall, river draining works, etc.
The Commission admits the expenditure as per Regulation 19 of Tariff Regulations,
2005 as it is towards land compensation and also on account of new works not in the
original scope of work.
(b) In respect of the other small hydro projects, viz., Periyar Vaigai IV, Bhavani
Barrage I, Bhavani Kattalai Barrage I & III, separate Petitions seeking approval of
capital cost have not been filed by the Utility. Further, as per the estimated cost
indicated in the present petition, the cost per MW of these projects are also in the
range of Rs.16 Crore/MW to Rs. 26.50 Crore/MW, which is extremely high when
![Page 24: TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Central … order/2017/CIP Order.pdf · 2017-08-02 · Page 1 of 52 TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Constituted under section](https://reader034.vdocument.in/reader034/viewer/2022042803/5f4e321c72a3781dfe6abe40/html5/thumbnails/24.jpg)
Page 24 of 52
compared with the norms specified in CERC RE Tariff Regulations. As separate
Petitions seeking approval of the capital cost of these Small Hydro projects have not
been filed by the Utility as already directed by this Commission in its order dated
31-01-2017 in M.P No.39 of 2012, the Commission has not considered the capital
allocation for these small hydro projects for the MYT Control Period from FY 2016-17
to FY 2018-19. The Petitioner is directed to file separate Petitions for approval of
the capital cost for the remaining Small Hydro projects for prudence check of
the Commission.
6.23. Dam Rehabilitation and Improvement Project (DRIP) works under World Bank
funded scheme for 38 dams have been taken up at an estimated cost of Rs. 272
Crore including IDC. Considering the progress of work, the capex allocation for this
project under progress is allowed.
6.24. The details of capital expenditure and capitalisation admitted by the

components. Accordingly, DPRs for SCADA enablers only were got sanctioned in 5
towns, viz. Coimbatore, Madurai, Tiruchirapalli, Salem and Tiruppur. However, Board of
TANGEDCO accorded approval for execution of schemes covered in 24 towns
cancelled (Distribution Strengthening Works only). Subsequently, Monitoring Committee
of IPDS (R-APDRP subsumed) in its 8th Meeting held on July 26, 2016 has decided to
revoke cancellation of Part-B schemes for 9 out of 24 towns based on revalidated
baseline data, amounting to Rs. 363.61 Crore sanctioned value. Also, Part-B scheme
for SCADA enablers only in Salem for Rs. 28.12 Crore has been cancelled by
Monitoring Committee to avoid duplication, since Part-B schemes in full has been
reinstated for Salem for Rs. 296.29 Crore. Therefore, Part-B schemes are being
implemented in TANGEDCO in total 88 towns having a total sanction value of Rs.
2841.21 Crore. The cancellation of Part-B schemes in remaining 15 out of 24 towns has
been upheld by Monitoring Committee and GoI and upfront amount (15% of sanctioned
cost) received towards these towns of Rs. 109.42 Crore along with accrued interest
shall be refunded or adjusted from future releases from GoI / Counterpart funding of
PFC.
6.38. The Commission observes that the implementation of R-APDRP has been
delayed. This delay has in turn led to delay in improvement of distribution
network and services. Hence, the Commission is of view that TANGEDCO should
take proactive measures to ensure the timely implementation of R-APDRP Part A
and Part B projects. The Commission, for the purpose of approval of Capital
Investment Plan, has considered the Capital expenditure as proposed by the

6.51. The Commission notes that the investment proposals submitted by the
petitioner for the distribution function for FY 2017-18 and FY 2018-19 is
comparatively lesser than that stated for the FY 2016-17 and the Commission has
taken into consideration the provision made by petitioner. However, it is the
responsibility of the Petitioner to ensure that an efficient distribution system is
developed and maintained and that non-provision of capital expenditure shall not
be cited as a reason for not achieving the targeted distribution loss levels and
other key performance indicators.
6.52. Further, the Commission directs the Petitioner shall maintain the record for
the scheme-wise actual capital expenditure incurred and actual capitalisation
done for each Distribution Circle/Zone separately and submit the same to the
Commission at the time of the next Tariff Petition. The Commission will approve
the actual Capital expenditure and actual capitalisation based on these
information, subject to prudence check.
6.53. The Petitioner has submitted the scheme-wise cost benefit analysis for existing
Generating Stations. The schemes proposed for existing Generating Stations are
intended to improve and retain the performance of Thermal Generating Stations. It is
![Page 39: TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Central … order/2017/CIP Order.pdf · 2017-08-02 · Page 1 of 52 TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Constituted under section](https://reader034.vdocument.in/reader034/viewer/2022042803/5f4e321c72a3781dfe6abe40/html5/thumbnails/39.jpg)
Page 39 of 52
noted that Hydro stations have also served out their useful life and Petitioner has
proposed to take up Renovation, Modernisation and Upgradation works at Moyar power
house, Periyar power house, Kodayar power house and Sholayar power house. These
works are generally to avoid loss of generation/improved generation. For Gas stations,
the materials released during Combustion Inspection and Hot gas path inspection have
been refurbished for future use, cost of which is less than the original cost of the item.
Repair cost is not only economical but also ensures spares are available.
The new capacity addition has been taken up by the Petitioner considering the
increasing demand and projected increase in the demand-supply gap.
6.54. The Petitioner has submitted the scheme-wise cost benefit analysis for the
Distribution function. The Petitioner has submitted the intangible benefits towards the
proposed Capital works such as reduction of AT&C losses, to ensure reliability of
supply, towards system strengthening, to meet the load growth, to reduce HT:LT ratio,
to relieve higher loading of distribution transformer, to reduce the outage time and
enhance operation flexibility, to improve the metering and accurate recording of
consumption and to avoid the human errors, augmentation of current carrying capacity
of conductor, easy identification of fault and avoid electrical accidents, easy isolation of
11 kV faults and avoiding loss in consumption, improvement in power factor, to improve
voltage regulation, voltage stability and VAR compensation, etc. In view of the above,
though the Commission appreciates that the Petitioner’s primary duty is to ensure
reliable power supply to all categories of consumers, the Utility shall also ensure that it
is done in the most economical way.

6.55. The Petitioner in its CIP Petition has not proposed any funding for the capital
works proposed for the existing Generating Stations. The Commission directs the
Petitioner to ensure that the financial assistance is tied up for proposed schemes.
6.56. The Commission has not considered the Capital Expenditure for New Generating
projects for recovery through tariff. Hence, the funding of the same shall be considered
at time of approval of capital cost and tariff for the respective Generating Stations in line
with the provisions of the Tariff Regulations.
6.57. Most of the schemes are being executed as funded schemes of MoP, GoI.
Balance schemes are being executed through loan from Financial Institutions or the
Petitioner’s own funds. In the foregoing circumstances, the Petitioner needs to ensure
that the financial assistance is tied up for proposed schemes.
6.58. Summary of CIP for FY 2016-17 to FY 2018-19
TANGEDCO has submitted Capital Expenditure of Rs. 4,755.46 Crore, Rs. 16,094.31

APPENDIX – I
STAKEHOLDERS’ COMMENTS, TANGEDCO’S REPLY
The following Section summarizes the key views/ objections/ suggestions and requests made by
stakeholders on the Capital Investment Plan (CIP) of TANGEDCO on the basis of the Hearing
held by the Commission on January 5, 2017. These include submissions received in writing as
well as submissions received and observations made at the Public Hearing. The Commission, in
order to accommodate maximum responses to the Public Notice had allowed the time for
submission of written comments till January 20, 2017.
In this Section, the Commission has addressed the views expressed by the stakeholders at a
single place. All comments received from the stakeholders by the Commission have been
provided to TANGEDCO, soliciting their responses. The responses so received have been
included under the relevant heads. Therefore, each view has been considered by the Commission
and appropriately addressed in this Order.
Regulatory Process
Stakeholder Comments
It is stated in the affidavit that the Chief Financial Controller (CFC) is well acquainted with the
facts of the case from records and is authorized to file the Petition. The Petition deals with
projects on the technical side of TANGEDCO whereas the CFC may be familiar with finance
and accounts. Hence, the CFC’s affidavit may not reflect the true situation.
The Petition for approval of the Capital Investment Plan (CIP) for FY 2014-15 and FY 2015-16
is still pending with the Commission. Hence, the filing of the present Petition may not be
appropriate as the previous CIP has not been approved by the Commission.
TANGEDCO’s Reply
TANGEDCO submitted that the projections for the CIP for FY 2016-17, FY 2017-18 and FY
2018-19 for Generation, Distribution and Projects is received in the office of (O/o) of
![Page 44: TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Central … order/2017/CIP Order.pdf · 2017-08-02 · Page 1 of 52 TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Constituted under section](https://reader034.vdocument.in/reader034/viewer/2022042803/5f4e321c72a3781dfe6abe40/html5/thumbnails/44.jpg)

CFC/Regulatory Cell from the concerned circles. Then, the projections are scrutinised by both
Technical and Accounts wings functioning in the O/o of CFC/Regulatory Cell. After detailed
clarifications and discussions with the concerned circles, the CIP has been filed along with
relevant particulars in line with Regulation 17 of the TNERC Tariff Regulations, 2005 and
Regulation 3(v) of the TNERC MYT Regulations, 2009, for its approval.
As regards the comment on the pending CIP for FY 2014-15 and FY 2015-16, the Commission
has approved the CIP for FY 2014-15 and FY 2015-16 filed in M.P.No.39 of 2012.
Capital Investment Plan
Stakeholder Comments
The Petition has no mention about the huge outstanding loan of Rs. 82,444.24 Crore till FY
2015-16.
The Petition envisages abnormal capital expenditure amounting to Rs. 1,34,883.40 Crore, which
is not commensurate with the year-wise investment from FY 2016-17 to FY 2017-18 (FY 2018-
19). The proposed capital expenditure project cost in the Petition does not tally with the year-
wise expenditure, i.e., the year-wise thermal and hydro power projects expenditure works out to
Rs. 3,35,004.28 Crore, whereas the estimated cost is shown as Rs. 1,19,964.07 Crore. Further,
there is no mention about the source of funding for this huge investment in the Petition.
The project completion period being followed at present is 40 months, whereas the Petition
states the same as 84 months upto FY 2021-22.
The entire CIP now proposed by TANGEDCO is aimed solely at getting relief from the financial
crisis. For this reason, it is presumed that TANGEDCO is in a critical financial condition and has
proposed an exaggerated plan outlay exceeding the existing loan of more than Rs. 82,000 Crore.
TANGEDCO has a bad and illegal habit of obtaining huge loans even without getting proper
approval from the Commission. The Commission also remains a silent spectator to the offenses
committed by TANGEDCO for years together, which has caused a great damage not only to the
financial status of TANGEDCO but has also caused the collapse of the economy of Tamil Nadu.
The above aspects of abuse of managerial functions by TANGEDCO has been proved by the
performance of TANGEDCO during FY 2015-16 in which period, TANGEDCO was capable
enough to bring down the annual loss to around Rs. 5,000 Crore from the previous period losses
of more than Rs. 13,000 Crore per annum.

TANGEDCO’s Reply
TANGEDCO submitted that the projections for the CIP for FY 2016-17, FY 2017-18 and FY
2018-19 for Generation, Distribution and Projects, is received in the O/o of CFC/Regulatory Cell
from the concerned circles. Then, the projections are scrutinised by both Technical and Accounts
wing functioning in the O/o of CFC/Regulatory Cell. After detailed clarifications and discussion
with the concerned circles, the CIP has been filed along with relevant particulars in line with
Regulation 17 of the TNERC Tariff Regulations, 2005 and Regulation 3(v) of TNERC MYT
Regulations, 2009 for the Commission’s approval.
TANGEDCO submitted that while indicating the year-wise projections for FY 2016-17, FY
2017-18 and FY 2018-19 for all the capital works for Generation, Distribution and Projects, the
total estimated cost of the capital works and the source of funding is also required to be
indicated, as per the format prescribed by the Commission. Accordingly, the total estimated cost
of the works/project is distributed in the years under review in proportion to the probable
progress and capitalisation of capital works to be achieved, by duly mentioning the source of
funding in the Remarks column. Some of the projects started in the preceding years will spill-
over into the years under review and some of the new projects that will commence in the year
under review will be completed within or beyond FY 2018-19. Hence, the total estimated cost
and the year-wise projections will be commensurate only when the new projects discussed in the
Petition are started and completed within FY 2016-17, FY 2017-18 and FY 2018-19 under
review without any addition or deletion in the scope of capital works during the execution
period.
TANGEDCO submitted that it has sought the Commission’s approval only for the projected
year-wise capital expenditure and capitalisation for FY 2016-17, FY 2017-18 and FY 2018-19
for Generation, Distribution and Projects out of total estimated cost of the capital works.
TANGEDCO submitted that under normal conditions, the stipulated completion period for the
thermal power projects (i.e., 500 MW and above) is between 39 to 42 months from the date of
award of the EPC contract. This has been clearly indicated in Booklet-I of the Petition for some
of the EPC contracts already awarded. Some of the projects to be awarded in the years under
review will be awarded and completed within or beyond FY 2018-19. Hence, it may not be
construed that the project completion period for those projects will be 84 months upto
FY 2021-22.

Generation Projects
Stakeholder Comments
At present, Basin Bridge Gas Turbine Power Station (BBGTPS) is operated in open cycle mode,
resulting in wastage of heat. Instead of cheap natural gas, expensive naphtha is used as fuel. Due
to these reasons, the power generated from this power station is costly and finds a place in the
bottom of the merit order dispatch, and hence, this Power Station is seldom put into service. If
this Power Plant is upgraded as a combined cycle power plant, the exhaust gas from the turbine
can be further used to generate steam and additional power at the same cost of fuel. A proposal
to upgrade BBGTPS as combined cycle power plant should be included in the CIP. The existing
old dilapidated power house building may be demolished, if additional space for the upgradation
is required.
Naphtha is costly. A Gas Company like HPCL, who supplied fuel to erstwhile GMR IPP in the
same area, may be able to supply gas to BBGTPS. If the Power Station is upgraded to a
combined cycle power plant and gas is made available, the power from this station will become
cheaper and it will advance in the merit order list. The power from this power plant will be very
useful to supply power to Chennai City, as 230 kV transmission lines to the city substations got
damaged during the recent 'Vardha’ cyclone.
At present, TANGEDCO has the capability to generate thermal energy at the rate of
approximately Rs. 3 per unit. At the same time, the private generators are not capable enough
and experienced to generate thermal energy at less than Rs. 5.50 per unit. Because of the
incapability, huge quantity of coal is being wasted leading to loss of national wealth.
TANGEDCO may consider acquiring such high cost private thermal stations, thereby it can
enjoy a great relief in the expenditure towards purchase of high cost power from the private
thermal power generators.
The staggering of power supply by load shedding in the substations of TANGEDCO is being
continued (maintaining three-phase supply for 14 hours and two-phase supply for 10 hours) as
addition of generation capacity during the 1980’s and 1990’s was meagre as compared to the
growth and therefore generating capacity is not sufficient to meet the increasing demand. The
peak load of 15,343 MW on April 29, 2016 is only a restricted demand. Supplying three-phase
power supply on 24x7 could be possible only if the on-going projects are expedited on war-
footing, if everything goes as projected in the CIP.
![Page 47: TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Central … order/2017/CIP Order.pdf · 2017-08-02 · Page 1 of 52 TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Constituted under section](https://reader034.vdocument.in/reader034/viewer/2022042803/5f4e321c72a3781dfe6abe40/html5/thumbnails/47.jpg)

Completion Reports should be closed for power generation plants. Penalties are not levied for
incomplete projects. This violation looms large in the case of EPC contracts, for e.g., the same
EPC contractor was awarded the 600 MW Mettur Thermal Power Station despite the debacle of
Valuthur Phase II (92 MW) power plant.
For Thermal Power Projects, avoidance of cost and time overruns, capacity addition, and growth
in net profit should be benchmarked. The practice of putting a CE/Civil in charge of projects
should be dispensed with.
Spinning Reserves, Equivalent Strategic Petroleum Reserve, Liquidity and Solvency are to be
maintained according to norms. Incursion of renewables (mainly wind energy) into the grid with
must-run status has led to backing down of thermal power stations, which hinders the merit order
(economic) dispatch operations. The base load power plants are not designed for operational
flexibility as they cannot be scaled back quickly and are inefficient at lower loads. This technical
specification is not indicated to the generating Units by designers and manufacturers for the
upcoming thermal projects.
TANGEDCO’s Reply
As regards BBGTPS, TANGEDCO submitted that the existing 4x30 MW Units utilize naphtha
as fuel and normally, two Units are put in synchronous condenser mode. The Units are seldom
used in Generation mode as per the requirements of State Load Despatch Centre (SLDC). Unit
III is under repair for the replacement of Compressor and Turbine casing at M/s. BHEL,
Hyderabad and is expected to be brought into service by the end of February 2017. All the three
Units are now in standby mode for generation mode / condenser mode of operation.
TANGEDCO clarified that as there is no natural gas connectivity available at Chennai presently,
the Units are running on naphtha with a variable cost of Rs. 15.79 per kWh. As regards the
comment on utilisation of natural gas, TANGEDCO submitted that M/s IOCL, Chennai has
proposed to install a new R-LNG terminal at Ennore by the end of 2018 and has agreed to supply
natural gas after regasification to BBGTPS by laying pipelines and sought the requirement for
generation. Accordingly, the required quantity of natural gas required for peak hour/base load
generation is furnished to M/s IOCL. Considering the present rate of 7.5 Dollars per MMBTU of
R-LNG, the approximate variable cost of generation for combined cycle would be Rs.4.61 per
kWh and for open cycle mode would be Rs.7.65 per kWh.
TANGEDCO also submitted that after getting confirmed allocation of R-LNG from M/s. IOCL
and analysing the cost of generation during that period of supply, proposal would be put up for
![Page 48: TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Central … order/2017/CIP Order.pdf · 2017-08-02 · Page 1 of 52 TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Constituted under section](https://reader034.vdocument.in/reader034/viewer/2022042803/5f4e321c72a3781dfe6abe40/html5/thumbnails/48.jpg)

the conversion of open cycle to combined cycle mode at BBGTPS with the cost of conversion of
120 MW open cycle plant into combined cycle plant of 180 MW at Rs. 360 Crore.
TANGEDCO submitted that the CIP for FY 2016-17, FY 2017-18 and FY 2018-19 for
Generation, Distribution and Projects has been filed in accordance with Regulation 17 of the
TNERC Tariff Regulations, 2005 and Regulation 3(v) of TNERC MYT Regulations, 2009 for
the Commission’s approval.
AT&C Losses
Stakeholder Comments
The line loss reported by the Ministry of Power based on the State Distribution Utilities annual
integrated rating was 21.7 % during FY 2013-14 and 24.4% in FY 2014-15, whereas,
TANGEDCO’s Petition states AT&C loss during FY 2012-13 as 18.4 % and same is claimed to
have been brought down to 17.96 % during FY 2015-16. Hence, the loss indicated in the Petition
is totally untrue and false.
The line loss assessed by TANGEDCO does not reflect the actual loss as considerable quantum
of energy consumed and losses are not metered for years together.
TANGEDCO has caused a huge loss of investment by the installation of metering arrangements
and Automatic Power Factor Correction (APFC) equipment in all the distribution transformers,
which remain a total waste as the same are not in use from the date of installation.
The measures to prevent theft of energy are not implemented properly to reduce the commercial
losses. Meter readings are not taken properly and the existing meters ought to be replaced with
static meters to quickly reduce loss of energy.
TANGEDCO’s Reply
TANGEDCO submitted that the CIP for FY 2016-17, FY 2017-18 and FY 2018-19 for
Generation, Distribution and Projects has been filed in accordance with Regulation 17 of the
TNERC Tariff Regulations, 2005 and Regulation 3(v) of TNERC MYT Regulations, 2009 for
the Commission’s approval.
As regards the line losses, TANGEDCO submitted that the line losses reported by the Ministry
of Power based on the State Distribution Utilities annual integrated rating during the year 2014

and 2015 is inclusive of the transmission losses, while the AT&C losses in the distribution side
as indicated in the Petition by TANGEDCO excludes the transmission losses. TANGEDCO has
clearly submitted in the Petition that by implementing various schemes sponsored by the
MoP/GoI such as Restructured Accelerated Power Development and Reform Programme
(RAPDRP), Integrated Power Development Scheme (IPDS), Deendayal Upadhyaya Gram Jyoti
Yojana (DDUGJY), etc., the AT&C losses will be reduced to 15% by FY 2019-20.
As regards the utilisation of metering arrangements, TANGEDCO replied that the installation of
metering arrangements and APFC equipment in the distribution transformers under RAPDRP-
PART-B scheme in 88 towns is in progress and is expected to be completed by March 2017.
Demand Side Management and Distributed Generation
Stakeholder Comments
There is no mention in the Petition about Demand Side Management (DSM). TANGEDCO is
duty bound to educate the consumers about DSM. Though there is separate DSM Wing
functioning in TANGEDCO, the Wing remains a liability with its very poor performance.
TANGEDCO should provide solar panels at the consumer point, especially for independent
residential consumers with a reasonable capacity of about 0.5 KVA. By this process, the low
consuming services can store the electricity during day time in the battery of the inverter and the
stored energy can be utilized by the consumer during evening peak hours to curtail the evening
peak demand. This scheme may be implemented for a minimum of 20 lakh services at the rate of
about Rs. 40,000 per service. The entire cost of installation should be borne by TANGEDCO.
TANGEDCO’s Reply
TANGEDCO submitted that being one of the best Utilities in the country, it is a front-runner in
implementing cutting-edge concepts and has never lacked in educating the consumers about
DSM. TANGEDCO is very well aware of the fact that the Ministry of Power set up Bureau of
Energy Efficiency (BEE) at the Central level for implementing the provisions of the Energy
Conservation Act, 2001, which came into force with effect from March 1, 2002, and
TANGEDCO is spearheading the movement of energy conservation across the State by
implementing various measures listed below:
![Page 50: TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Central … order/2017/CIP Order.pdf · 2017-08-02 · Page 1 of 52 TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Constituted under section](https://reader034.vdocument.in/reader034/viewer/2022042803/5f4e321c72a3781dfe6abe40/html5/thumbnails/50.jpg)
Page 50 of 52
i. The DSM Wing is already creating awareness through “EC Day and Week” programme
to the general public across the State during the month of December every year in all distribution
circles.
ii. The Energy Conservation Day/Week is usually arranged to be celebrated from December
14th
to 20th
across the State every year in a grand manner by organizing various events.
However, during 2015, the “National Energy Conservation Day and Week” could not be
celebrated in a grand manner due to torrential rains and flood, which wrecked the entire State
during the first week of December 2015 and it was a low-key affair and during 2016 due to State
mourning, the National Energy Conservation day/week celebrations were cancelled.
iii. As a permanent measure, the slogan on Energy Conservation, i.e., “Save Electricity” is
being sent as SMS to about 2.6 Crore consumers along with the SMS alerts for payment of CC
charges thereby instilling awareness from grass root level to higher echelons of society.
iv. Energy conservation tips along with other suggestions have been displayed on the web-
site of TANGEDCO. Energy conservation slogans have been printed in EB cards and Calendars.
v. The training wing of TANGEDCO emphasizes the need for Energy Conservation and
also propagates the usage of energy efficient lights and star rated equipments in all training
programmes/ workshops/ seminars conducted for school children and public throughout the year.
vi. Among the general public, targeting the student community who form the future
generation will yield long-lasting results to the Utility as well as to the nation. As known by the
common adage “Catch Them Young”, the concept of energy conservation if sown in the young
minds, will be carried forward throughout their life and to all places wherever they go. They will
also help to spread this message to all those with whom they interact without hesitation unlike
adults. Hence, the programme of Energy Conservation awareness to school students has been
initiated across the State through the officers of the distribution network from October 2014
onwards. About 10 lakh students have been addressed so far.
vii. Flex boards with the message of energy conservation have been erected at TANGEDCO
headquarters and EDC offices at Chennai.
viii. Seminar/talk/lecture on Energy Conservation for disseminating the knowledge and the
latest technical knowhow is being taken up for Central Government sectors, micro / small /
medium enterprises, private / public sector, MNCs and higher educational institutions.
ix. TANGEDCO widely propagates and monitors the directives issued vide GO.126 dated
November 10, 2008 and GO.95 dated August 2, 2012 to adopt energy conservation measures in
![Page 51: TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Central … order/2017/CIP Order.pdf · 2017-08-02 · Page 1 of 52 TAMIL NADU ELECTRICITY REGULATORY COMMISSION (Constituted under section](https://reader034.vdocument.in/reader034/viewer/2022042803/5f4e321c72a3781dfe6abe40/html5/thumbnails/51.jpg)

all Government offices and buildings including Local Bodies, Public Sector Undertakings, etc.,
by using energy efficient lights and appliances stipulating the usage of LED lamps in locations
such as pathways, entrances, corridors, rest rooms, etc., of the buildings considering its
efficiency and life cycle cost.
x. TANGEDCO through Hello FM and Rainbow FM (radio programmes) has created
awareness among Chennai residents on issues related to general grievances, LT billing and
Energy Conservation during 2012.
xi. During 41st India Tourist and Industrial Fair 2014-15 at Island Grounds, Chennai,
TANGEDCO conducted a stage show (drama) named ‘Minsara Thiruvilayadal’ with the theme
of energy conservation awareness and theft of energy. The theme and script of the above show
was developed and performed by TANGEDCO’s officers/staff. The programme was performed
in four places successfully and reached more than 10,000 students and general public.
xii. TANGEDCO celebrated “Electricity Awareness Week” in all districts across the State
between 21st and 27
th of August 2012 with an aim to create awareness on electrical safety,
electricity theft and prevention and energy conservation by distributing a Handbook on the same.
Ujwal DISCOM Assurance Yojana (UDAY)
The decision of the Government of Tamil Nadu (GoTN) to join the Government of India’s
(GoI’s) UDAY on the condition that there would be no revision of tariff by TANGEDCO for
another two years and that the GoI would help TANGEDCO under UDAY to reduce the losses
incurred, is welcome.
CIP for each year of the MYT Control Period from FY 2016-17 to FY 2018-19 ought to be
modified incorporating the features of UDAY.
The UDAY scheme is not consistent with the CIP approved by the Commission. Further, under
the UDAY scheme, it has been stated that the tariff shall not be revised, which is inconsistent
with the Commission’s mandate to undertake suo-motu Tariff revision in case the Utility does
not file the Petition.
TANGEDCO’s Reply
TANGEDCO submitted that it is thankful for the suggestions to incorporate the features of
UDAY in the CIP and also the general comments on theft of energy, meter reading and
replacement of existing meters with static meters.

3 Coutant bottom slope tubes & acute bends
in Unit II Boiler
Design, Manufacture, Supply, Erection, testing and
Commissioning of Coutant bottom slope tubes & acute bends for
Unit II Boiler of 210MW
Due to the usage of low calorific value of Vizag coal, the quantity of
coal used is 145 to 165 T/hr as against the designed quantity of 90 T /
hr which results in more ash content and mass flow leading to
increase in velocity and finally end up with high erosion. Due to the
usage of more quantity of high ash content Vizag coal and hot
clinkers falling over the slopped tubes, it got eroded and more prone
to puncture in this area and subsequent unit outages and generation
loss.

to ESP inlet with New insulation materials.
High air ingress takes place through the eroded opening of the FG
ducts in Unit 5, leading to overloading of ID current , loss of Power
generation and higher auxilary Power Consumption. Hence eroded
flue gas ducts are to be renewed to rectify the above problem.

22 Condenser system in Unit IV. Renewal of condenser inlet and outlet pipes & Provision of debris
filter in condenser cooling water inlet line in Unit IV.
The condenser performance is dependent on cooling water
temperature and cooling water flow rate. The cooling water flow rate
is getting affected due to accumulation of considerable amount of
marine growths over the tubes of the condenser. In consequence,
temp. gets raised and vacuum lowered. This results in increasing of
Turbine heat rate and losses to Board. In order to clear the marine
growths and sea grass from the cooling water admitted into the
condenser and to maintain the rated cooling water flow, debris filter is
essential.

During summer seasons the problem aggravates and the ACW

leading to reduction in power generation. As all the three available
heat exchangers are in service to keep the temperature under control
we can’t clean a particular heat exchanger when the unit is generating
to its full capacity.This will solves the problem of reducing the power
generation in case of raise in ACW temperature during summer
season while the grid warrants maximum power generation.

28 Modification of Shuttle Feeder-2A/2B at
Secondary Crusher House-II
Dismantling of existing 1400mm Belt Shuttle Feeder along with all
accessories and design, engineering and supply of 1800mm belt
width shuttle feeder
The existing belt width of shuttle feeder-2A/2B are 1400mm and can
carry the load upto 800T/Hr. Much difficulties are being experienced
while handling higher discharge resulting in frequent stoppage of
shuttle feeders and ultimately cause higher ship demurrage charges.
In order to overcome the above, it is proposed to modify with belt
width of 1800mm

43 ESP Unit II Revamping of Unit II ESP by replacing the internals in the first two
rows (8 fields) and overhauling of the remaining 12 fields in Unit
II.
The ESP internals (Except collecting electrodes) in the first two rows
(A1, A2, B1, B2, C1, C2, D1 &D2) are in service right from the date of
commissioning. Due to high ash content in the coal, the internals got
eroded, leading to tripping of ESP fields. This affects the collection
efficiency of the ESP leading to higher SPM level in the flue gas.
Hence, in order to solve the above problems, it has been proposed to
replace the ESP internals during the forthcoming capital overhaul for
the year 2016-17.

Design, Manufacture, Supply, Erection, testing and

Unit I Boiler of 210MW
Due to the usage of low calorific value Vizag coal, the quantity of coal
used is 145 to 165 T/hr as against the designed quantity of 90 T / hr
which results in more ash content and mass flow leading to increase
in velocity and finally end up with high erosion. Due to the usage of
more quantity of high ash content Vizag coal and hot clinkers falling
over the slopped tubes, it got eroded and more prone to puncture in
this area and subsequent unit outages and generation loss.

Whenever the sharp edged iron pieces/ferrous materials are coming
along with the coal it may tear the conveyor belts. Moreover, if it
enters into the coal mills, it will damage the mill internals, costly
bearings etc also leads to mill outage. To ensure boiler stability at
such times ,heavy oil is being introduced which inturn additional
revenue loss to TANGEDCO and also partial generation loss . Hence

67 Yard conv.49 & 54 Revamping of yard conv.49 & 54 The conveyors 49 & 54 are vital trunk yard conveyors in the coal yard
for receiving the coal discharged from two coal jetties and feeding coal
to bunkers of all the five units of TTPS. These conveyors are in
continuous service for more than 19 years. Break down on these
conveyors affects the coal stacking process on receipt of coal from the
ships and coal feeding process in the units bunkers through
reclaimers in the yard. Monetory loss will occur if the coal handling
process is affected. Hence revamping of conv. 49 & 54 is essential

Additional bogie wheel drive assembly in Stacker-I Stacker-I machine is being used for receiving coal from jetty’s and
feeding to unit bunkers uninterruptly. There are 4Nos. drive system
available in Reclaimer I machine provided at the front and middle
portion of the machine and hence travel problem does not occur even
in full load condition. But in Stacker I and II machines there are only 2
drive systems available. If anyone of the drive gets failed may lead to
stoppage of the machine affecting coal receiving from jetty’s. Hence
by providing additional drive system in the middle of stacker boom
structure the problem can be minimized.

Up gradation of Turbine Control system from Iskamatic based
modules to newer system in Unit-V.
The existing Siemens based ISKAMATIC systems were supplied &
commissioned by M/s. BHEL, during 1991 in Unit 5 and are in service
till date. Due to obsolescence of the Iskamatic modules, no spares are
available from the original supplier (M/s. BHEL), who have also
withdrawn service support for the system long back.The failure of the
existing Iskamatic based controllers leads to loss of control of critical
equipments which results in damage to the main equipment and
hence results in loss of generation. Hence, to stave off the
obsolescence and derive benefits of advancement in technology, it is
essential to upgrade the existing EAST Iskamatic control system to a
newer version of Digital system.

Frequent outage of coal unloading
equipments is primarily due to worn out
condition of machine part and failure of the
components due to aging and prolonged
usage. Hence, replacement of worn out parts
and overhauling of the existing parts are
essentially required to be carried out to
increase the coal handling capability of the
conveyor system and to reduce the frequent

and to undertake trouble free coal unloading

Nos.
Due to prolonged usage for more than 25 years
these dust extraction systems became
ineffective and the ambient air quality in CHP-
I&II working area are beyond the norms
stipulated by pollution control board. The
vibration is very high in the dust extraction
blower due to worn out of impeller, and
imbalance in dynamic balancing. Hence the
bearings used in the drive shaft has failed and
the drive shaft became bend. This problems
creating hardship in running the dust
extraction system continuously.Due to this the
entire working area of CHP-I&II has been

MoU. MoU in respect of Unit III & IV has
already been terminated. Similarly MoU of
Unit I & II are likely to be terminated. On
termination of MoU, PDFACS have to be
maintained by TANGEDCO.
These PDFACS have served 12 years already.
These system handle the abrasive nature of dry
fly ash. These system have been in continuous
service since its commissioning. Hence erosion
and corrosion is more in these equipments due
to normal wear and tear. Hence R&M of
PDFACS is essentially required to improve the
ash collection & ambient air quality & revenue
to the TANGEDCO.

On expiry of the
MoU between
TANGEDCO &
Cement Companies,
the existing PDFAC
systems have to be

the existing PDFAC
system has served
beyond the life
period. The
equipments are
conveying abrasive
nature dry fly ash
continuously
throughout the year.

connected through SCSI interface and are
working with Windows Server 2003 (32 Bit) as
operating system.
Now, the SCSI interface and Windows Server
2003 Operating System are obsolete and not
available in open market.
Also latest available servers and OS
(Windows server 2008 or above) in open
market could not be interfaced with the
existing ABB DCS system. Hence, updation of

breakdown occurs in ASDP, it will affect the Ash slurry
mixture pumping and the slurry level in the trench will
increase which leads to stoppage of scrapper feeder and

element profile in Unit-I
Due to supply of low colorific value of coal, more
quantity of is being consumed to attain the full load
and correspondingly more quantity of primary and
secondary air is fed to the boiler. Hence, the leakage
percentage is always more than 10% in the Air pre
heater which is more than the designed allowable
leakage percentage of 8% which result in overloading
of ID,PA & FD fans. Therefore, it is proposed to

deformed along with the erosion of gasket seating
portions, beyond repairable condition, leading to
leakage of ACW or mixing of ACW with sea water.
This causes shutdown of the Unit and wastage of entire
ACW water. Hence, it is proposed to renovate /
refurbishment one complete PHE assembly in units 1 &
2 during the COH 2016.
1.35Yet to be
obtained
Partial loss of generation due to raise
in H2 gas temperature and bearing
temperatures of Turbine & Boiler
auxiliaries is considerably reduced
due to proper maintenance of ACW
temperature. Cost of generation is
reduced due to avoidance of wastage
of ACW (DM water).

Handling division fly
ash conveying lines
Providing spare line for ash
conveying lines from ESP to
fly ash silos
There are two lines available for fly ash conveying from
ESP (A,B,C,D passes) buffer hopper to fly ash silo. These
lines are getting punctured frequently due to errosion.
There is no standby or spare line available due to which
the ash conveying is stopped frequently for attending the
damaged portions causing the raise of level in ESP hoppers
due to which the fields are got shot. Hence this spare line
is essentially required for continuous evacuation of fly ash
from ESP hoppers and to maintain a sustained
generation.

repair bay and extension of Hoist moving rails for
handling of heavy weight mill retrieved spares during
overhauling of coal mills. Hot air gates, Hot air dampers,
cold air gates and cold air dampers were provided at
various levels. Necessary approach platforms are not
provided by the M/s.EPC contractor during erection.
Much difficulties are being faced for maintenance of above
said gates and dampers while unit is in service condition.

This proposal is for procurement of 1 set of roller tyre
complete assembly complete set(1 set consists of 3 Nos
Roller assemblies) for keeping the assemblies as ready for
replacing the wornout roller assembly, to be retrived from
any mill which will be taken up for overhaul within the
shortest possible time and hence the period of overhaul
could be minimised from 30 days to 15 days and thus
increasing the availability of the mills for trouble free
operation and sustained generation for which the
proposed 1 set of Roller Tyre complete assembly (1 set
consists of roller assemblies ie., for 1 mill requirement) is
very much essential. This type of coal mills are not in
service in TANGEDCO Thermal Power Plant.

6 EM Division HV
Breaker and EHV
Insulator of SAB type
230 kV GIS HV Breaker
Compartment (Single pole)
Essentially required for failure replacement in case of
emergency. SABs transfer power from GIS to
Transmission lines. Failures are susceptible in joints.
Hence, availability of spare SABs are required to ensure
continuous evacuation of power. Failure of breaker pole
will result in the non-availability of 230 kV circuit. If spare
active part is available, the downtime can be minimized to
restore the circuit early.

Procurement of 1 No
cartridge for TDBFP
To maintain generation of 600 MW, 2 Nos. TDBFPs will
have to be in service. If any problem arises in any one of
the TDBFP, MDBFP will be put into service which
increases the auxiliary consumption by 8 MW and also the
unit will be in service without standby Feed pump. In that
condition if any problem arises in the running TDBFP, the
unit load has to be reduced to 300MW and in case of any
problem in MDBFP the unit could not be lit up which will
further result in forced outage of the unit. Hence
procurement of 1 No TDBFP as spare is very much
essential.
