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.

4.1. The relevant provisions of the Tariff Policy notified by Government of India on

January 6, 2016 with respect to the CIP are reproduced below:

“5.11 Tariff policy lays down … …

a) Return on Investment

… … …

ensure that these are reasonable and to achieve this objective, requisite benchmarks

Page 11 of 52

on capital costs should be evolved by the Regulatory Commissions.

b) to (h)… … … …

g) Renovation and Modernization

… … …

A multi-year tariff (MYT) framework may be prescribed which should also cover

capital investments necessary for renovation and modernization and an incentive

framework to share the benefits of efficiency improvement between the utilities and the

beneficiaries with reference to revised and specific performance norms to be fixed by

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

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 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 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 of 52

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 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 of 52

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 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 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 of 52

(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 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 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 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

Commission for the DRIP works, Bhavani Kattalai Barrage II and Bhavani Barrage II

are furnished in Annexures 14-16.

6.25. The abstract of the overall capital expenditure and capitalisation proposed by

the Petitioner and approved by the Commission for Generation function for the

purpose of recovery through tariff, are shown in the Tables below:

6.26. The Commission has scrutinised the details of various works submitted by the

Petitioner.

6.27. Provision has been made by the Petitioner for extension of LT, LT-CT and HT

supply to various service categories and establishment of new 33 kV sub stations and

improvement works in sub-stations.

6.28. The objectives of the R-APDRP Scheme are to provide quality and reliable

power supply to the consumers and to bring down the AT&C losses below 15%. The

Petitioner has taken up the project in two parts, viz., Part-A and Part-B.

6.29. For R-APDRP Part A, an amount of Rs.417 Crore for Information Technology

implementation in 100 towns and Rs.182.17 Crore for SCADA/DMS (Supervisory

Control and Data Acquisition System/Distribution Management System) implementation

in 7 towns have been sanctioned. The objective of Part A implementation is to achieve

reliable and verifiable baseline data system in all towns with population greater than

30,000 as per 2001 census (10,000 for Special Category States). The installation of

SCADA/DMS for towns with population greater than 4 lakhs and annual input energy

greater than 350 MU is also envisaged under Part-A.

6.30. TANGEDCO has submitted that 100% loan is provided under R-APDRP for

Part-A projects, which shall be converted to grant on completion and verification of the

same by Third Party Independent Evaluating agencies (TPIEA) appointed by

MoP/Nodal Agency.

Page 28 of 52

6.31. Detail Project Reports (DPRs) for Part A-Information Technology implementation

have been sanctioned on February 27, 2009 for 27 towns amounting to Rs. 70.04 Crore

and on June 30, 2009 for 83 towns amounting to Rs. 346.96 Crore. DPRs for Part A-

SCADA implementation have been sanctioned on December 8, 2010 amounting to Rs.

182.17 Crore.

6.32. The Commission notes that as per sanction, Part A projects are to be completed

within 3 years from the date of sanction for getting the loan converted into grant.

Further, the extension had been given up to June 30, 2016 in the 6th meeting of the

Monitoring Committee for implementation of IPDS held on December 10, 2015.

Subsequently, the completion date has been further extended up to March 31, 2017 in

the 8th meeting of Monitoring Committee of IPDS implementation held on July 26, 2016.

6.33. As regards the present status of Part A-Information Technology implementation,

the Petitioner submitted that out of 110 towns, 102 towns have been made “Go Live”

and the balance 8 towns are proposed to be made “Go Live” in phases.

6.34. As regards the present status of implementation of Part A-SCADA

implementation, the Petitioner submitted that SCADA/DMS Control Centre equipments

have been commissioned in all the 7 towns, viz., Chennai, Madurai, Salem, Trippur,

Tirunelveli, Trichy and Coimbatore. SCADA/DMS including field equipments, viz., Sub-

station RTU (Remote Terminal Unit) and FRTU (Feeder Remote Terminal Unit) in

RMU’s (Ring Main Units) has been completed in Trichy and Tirunelveli. Installation and

Page 29 of 52

commissioning of SCADA equipments and DMS will be completed in the balance

towns.

6.35. Part B schemes include regular distribution strengthening works aimed at actual

and demonstrable performance in terms of reduction of AT&C losses in the project area

to less than 15% on a sustained basis for five years commencing one year after the

completion of Part A works besides reduction of AT&C losses for entire utility at 1.5%

per year. Successful completion within the schedule time for Part B schemes subject to

above condition will entitle TANGEDCO for conversion of 50% of the loan amount into

grant.

6.36. TANGEDCO submitted that Part A towns with baseline AT&C losses of above

15%, which is to be verified by a TPIEA, have been considered for implementation of

Part B schemes. Also, SCADA/DMS is implemented in seven towns and SCADA

enabling components like Ring Main Units and Sectionalisers required for this

implementation are proposed in Part B schemes.

6.37. Because of delay in establishment of baseline AT&C Losses, DPRs for 87 towns

were submitted and got sanctioned, based on computed AT&C losses of the respective

towns. However, after the establishment of baseline AT&C losses, Ministry of Power

(MoP), Government of India (GoI) cancelled the sanction for 24 towns. Further, 12 more

towns became eligible and DPRs for those towns were sanctioned by MoP, GoI.

MoP/GOI issued fresh guidelines for SCADA towns with baseline AT&C losses of less

than 15%, as eligible under Part B schemes for provision of only SCADA enabling

Page 30 of 52

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

Petitioner, subject to the condition that the Petitioner shall adhere to time lines

Page 31 of 52

proposed for implementation. Any variation in case of actual capital expenditure

shall be taken into account at time of True-up for respective year.

6.39. The Petitioner has taken up certain works under IPDS, funded by MoP, GoI,

which is implemented with the objectives of 24x7 Power supply for all, reduction of

AT&C Losses, and electrification of all urban households. The scope of IPDS includes

strengthening of sub-transmission and distribution network, metering of feeders,

boundary points, Distribution Transformers and to all consumers, completion of missing

links under the establishment of National Optical Fiber Network (NOFN), and provision

of Solar panels in Government building and Net Metering. The funding for such works

has been considered as upfront grant of 60% by MoP, GoI, lending from Financial

Institutions of 30% and utility own funds of 10%.

6.40. TANGEDCO submitted that Detailed Project Reports (DPRs) of 37 Nos. of

distribution strengthening works including metering and roof top solar panels covering

522 towns across 37 Nos. EDC for a total value of Rs.1561.31 Crore were submitted to

M/s. Power Finance Corporation Ltd. (PFC). Formal sanction letter has been issued by

PFC on March 7, 2016 and accordingly the schemes have to be completed within 30

months, i.e., by September 6, 2018. Accordingly, the Tripartite Agreement was

executed between PFC, MoP, GoI and TANGEDCO in respect of implementation of

IPDS on July 19, 2016.

6.41. As per guidelines, a Project Management Agency (PMA) is to be appointed to

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 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.

Page 40 of 52

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

Crore and Rs. 18,379.05 Crore for its Generation function for FY 2016-17, FY 2017-18

and FY 2018-19, respectively. Similarly, for Distribution function, it has submitted

Capital Expenditure of Rs. 5,577.12 Crore, Rs. 3,016.39 Crore and Rs. 2,101.38 Crore

for FY 2016-17, FY 2017-18 and FY 2018-19, respectively.

Based on the approval of Capital Expenditure and Capitalisation as discussed in

foregoing paras of this Order, the summary of approval of CIP is given in the following

Tables:

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 of 52

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


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.

Page 45 of 52

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


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 of 52

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 of 52

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


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

Page 49 of 52

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


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 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 of 52

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.

Page 52 of 52

TANGEDCO also submitted that the features of UDAY scheme in Tamil version is readily

available on TANGEDCO’s website, viz., www.tangedco.gov.in.

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.

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

temperature could not be maintained within permissible limits

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.

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.

for Unit I Boiler of 210MW

Design, Manufacture, Supply, Erection, testing and

Commissioning of Coutant bottom slope tubes & acute bends for

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.

68 Additional bogie wheel drive assembly in

Stacker-I

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.

Replacement of various sizes of 6.6KV PILC Cable for HT Motors

and HT Transformers in Unit-I

The existing PILC Cables have served 34 years, much more than its

life period of 25 years. The insulation properties of the existing PILC

Cable are in deteriorated condition. Sudden failure of these cables will

lead to disturbance in the Electrical System thereby causing loss of

generations. Hence to maintain uninterrupted power supply to HT

Motors and HT Transformers in Unit-I, the essential existing PILC

Cables are proposed to be replaced by XLPE FRLS Aluminium

armored HT power Cables.

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.

56 Replacement of wornout

slewing ring in SCR machines

and other allied works etc.,

The SCR machines are erected and

commissioned during the year 1988 and had

served more than 26 years. Further it is

evident that if any failure occur in slew

bearing ring of SCR machine, it would affect

normal operation of machine besides the coal

feeding to unit. Therefore it is proposed to

renew the slewing ring available at Central

stores in SCR machine–I / II as and when

required.

2.00 Proposal under

preparation

The slew ring

bearing plays and

important role in

distributing and

with standing

inordinate load

during reclaiming of

coal and therefore

the availability of the

machines through

out the year have to

be constantly

monitored.

The Travelling Tripper in conveyor 11A /11B

are equipped with electro magnetic brake and

hence while operation if any problem occurs, it

will not stop immediately. Due to the weight

of the coal in the discharge chutes it leads to

move forward. To avoid such problem it is

proposed to install hydraulic brake in the

Travelling Tripper 11A/11B in a phased

manner to ensure trouble free operation of

travelling tripper.

59 Pull chord status mointoring

system with wire less

At present great difficulties are being

experienced to identfy the operated pull chord

switches and lot of time is being consumed to

reset the switches operated, since the location

staff have to go around both sides of conveyor

systems to identify the operated pull chord

switches. Practically much hardships are

being experienced and hence to avoid these

diffculties and reduce the down time of

conveyor systems it is essential to provide

pullchord status indications in MCC-I through

wireless type.

commissioning of DXT bag

filter in M-I sub division - 10

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

polluted and whole area became dusty. Hence

neat working atmosphere could not be

maintained.

4.00 Proposal under

76 R&M Unit-III - Proposal for R&M of

C&I FSS system into new DCS

system.

1. FSS System has involved thousands of

different types of electronic cards. This system

has served more than 25 years. It has become

aged and obsolete. Due to ageing of the

system it has developed so many operational

problems 2. Now, M/s. BHEL stopped

manufacturing of these types of electronic

cards and more over these cards are not

available in open market. Even, M/s. BHEL is

not ready to repair any of the defective

electronic cards, due to non availability of

spares and technology advancement. 3. The

frequency of failure of electronic cards now

has increased & unexpected failure of these

cards may take place in future which may

cause generation loss. Hence, it is important

that the existing deteriorated system has to be

replaced necessarily and immediately.

8.00 Approval of

the Electro Hydraulic Thrust Brakes which arrest the

movement of the machine is wornout condition.

Because of this the reclaimers / Travelling Tripper-B

tend to move backwards while reclaiming/feeding

causing decrease in loading of coal and also move

forward or backwards. Because of this movement the

Reclaimers have overshot the stoppers and causes

Providing spare line for ash

conveying lines from ESP to

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

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
