different sets of documentation. From this point of view of COD, for

generators under the purview of Section 62 (where the tariff is approved by

a Regulator) the COD shall be as per the provisions of Terms and

Conditions of Tariff 2014-19, if CERC has determined the tariff. It was

noted that this includes cases like NTPC generators and also generators

like Torrent Power whose tariff is determined by CERC. As per theprevailing Tariff Regulations the requisite certificate is to besubmitted by the company to the respective RPC and RLDC, andno other document is required to be submitted, as this provisionwould not be applicable for NTPC and to the Generators under theperview of section 62 of IE act 2013. If tariff is determined by State

in operation since the last one year.”


ITEM NO 2 : SYSTEM STRENGTHENING

2.1Conversion of fixed Reactor to switchable Reactor;

Member Secretary, WRPC informed that during 28th WRPC/TCC meeting,

PGCIL had proposed that fixed Line Reactors installed in following lines be

converted to switchable Line Reactors so that they could be utilised as Bus


Reactors when line is out, which may be required to maintain Voltage profile.

The list of such lines with reactors that require to be converted to switchable

line reactors are at the following locations :

During 28th WRPC/TCC, it was recommended to convert the above fixed line

reactors as switchable reactors without any system study.

TCC: During TCC, PGCIL representative stated that they anticipated dynamic

overvoltage problems and therefore referred the matter to the Standing

Committee on PSP. However it could not be taken in the recent SCM. TCC

discussed the issue but it was difficult to comprehend the need for dynamic

overvoltage studies as only a switching breaker is introduced. PGCIL

representative pointed out that providing breakers would require SCM

recommendation for investment approval. MS WRPC pointed out that in that

case PGCIL may take SCM approval and put up in the WRPC meeting and

28th WRPC approval to go ahead without studies may be cancelled.

WRPC: Director(O),PGCIL proposed that PGCIL may go ahead with the

proposal based on the 28th WRPC approval and get a ratification from the next

SCM and inform the same in the next WRPC meeting after SCM approval.

WRPC agreed to suggestion of PGCIL.


2.2 Extension on 220 kV Network at GIS Navi Mumbai station

Background: During 28th WRPC/TCC meeting, Member Secretary WRPC

informed that POWERGRID had communicated that 400 kV GIS at Navi

Mumbai is likely to be commissioned by the end of May, 2015, as the cable

laying works are in full swing and shall be completed before March 15. Further

they requested MSETCL to extend 220 kV grid from Navi Mumbai GIS station

to their load centers.

Accordingly MSETCL was requested to indicate the progress for installation of

220 kV line from GIS Navi Mumbai.

During TCC Director, MSETCL enquired about the status of the incoming

source of 400 kV Vapi-Navi Mumbai at Navi Mumbai station. It was informed

by GM – PGCIL(HO) that 400 kV Vapi-Navi Mumbai line is not coming, and

this was already reported at Standing Committee meetings. With the line not

coming to Navi Mumbai, Director MSETCL informed that the substation was

not beneficial to Maharashtra system, as there is no source of input power to

Maharashtra grid. Hence laying 220 kV network from MSETCL system to Navi

Mumbai would only mean unnecessary congestion in Maharashtra system and

only charging of substation at Navi Mumbai.

Further with respect to LILO of 400 kV Lonikhand-Kalwa MSETCL line at Navi

Mumbai. ED-WR1, PGCIL informed that the cable work is in advanced stages

of completion, and the same would be ready by May end along with the

substation.

Director, MSETCL requested for relocation of the asset of GIS Navi Mumbai to

more useful place for better utilization of the same as the existing asset is not

serving any useful purpose to Maharashtra system. GM – PGCIL(HO)

informed that these projects have been executed after due approvals from

competent authorities. Further progress and problems faced have been

reported at SCM. At this stage it is not possible for them to consider any

relocation of asset.


During the 28th WRPC Meeting, Executive Director, MSETCL explained

Maharashtra’s position with respect to relocation of asset, as already given

above, and requested to take the matter to CEA before taking a decision.

AGM-PGCIL(HO) explained that the non availability of 400 kV Vapi-Navi

Mumbai was informed to SCM. However at that time Navi Mumbai was not

discussed for relocation. A decision to relocate Navi Mumbai could have been

taken at that time itself, in that case, before award of any contract. However

since the project has since been in advance stage of completion, at this stage

it was not acceptable to relocate.

She pointed out that relocation of an asset is much more costly than

establishing a new asset. There are experiences of Sasaram HVDC being

thought of relocation but that was not feasible and given up. However it may be

beneficial to replan the network in that area, so that the asset can be utilized.

Hence the substation should be allowed to be charged.

Regarding the issue of charging of the substation, Director, MSETCL stated

that since the asset is not beneficial at all, charging would unnecessary

commercially burden the Maharashtra consumer with no benefits. This could

not be permitted. If however there is benefit after re planning, the issue of

charging can be thought of. Hence matter requires discussion with CEA.

AGM-PGCIL(HO) explained that non charging of PGCIL asset, when it has

been created after due approvals cannot be acceptable to PGCIL. PGCIL

requested that the station be allowed to charge. But this was not acceptable to

Maharashtra, as there is no benefit to their system.

During the 28th WRPC meeting Chairperson, WRPC suggested to take up the

issue with CEA by MSETCL and PGCIL with respect to utilization of the

substation as well as charging.

TCC/WRPC: Member Secretary, WRPC informed that the above matter was

deliberated in the SCM and he appraised of the the above agenda position.

The SCM decided to form a group of representatives from CEA,

POWERGRID, MSETCL and would look into the alternative arrangement of


feeds to Navi Mumbai station. MS, WRPC informed that any progress on the

same would be intimated to WRPC.

WRPC noted.

2.3 220 kV Extension feeders at 765/400 kV/220 kV sub-station atAurangbad.


informed that POWERGRID’s 765/400/220 kV sub-station at Aurangabad was

commissioned in January, 2014 and in operation from the above date. The ICT

765/400 kV is loaded but 400/220 kV is charged. Further, there is no 220 kV

network to cater the load of Aurangabad sub-station to nearby load centres.

MSETCL was requested to make the construction of 220 kV lines at the

earliest so that the load can be catered through POWERGRID’s sub-station at

Aurangabad to different load centres in Maharashtra.

Director, MSETCL informed that 220 kV Chitegaon-Shendra evacuation line at

Aurangabad shall be completed in about six months time.

TCC/WRPC: Director, MSETCL informed that for the 220 kV Chitegaon-

Shendra evacuation line at Aurangabad tender has been floated. It is expected

that line shall be completed in about six months after award.

WRPC noted.

2.4 Readiness of Kudus sub-station :


informed that MSETCL is constructing Kudus sub-station near Padghe.

POWERGRID’s 765 kV/400 kV GIS Padghe sub-station is likely to be

commissioned in May/June,2015. The 400 kV line from Powergrid Padghe GIS

station is likely to be completed by the end of May, 2015. In order to

evacuate power from POWERGRID sub-station, MSETCL has to keep ready

Kudus station by May, 2015. Director MSETCL informed that outgoing feeders

at Kudus along with Kudus substation is expected to be completed in about

one year time (by June 2016).


TCC/WRPC : POWERGRID/CTU representative informed that as per theoriginal scheme 400kV D/C from Tarapur is planned to 400kV Kudus and400kV Kudus to 400 kV Padghe GIS of Powergrid. It was also informedthat the 400kV line from Powergrid Padghe GIS station would becompleted by October 2015. Therefore in the 38th SCM it was decided thatsince Kudus S/S is expected to be commissioned by June 16, as aninterim arrangement the 400kV D/C lines from Tarapur S/S be terminatedat Nagothane S/S, by passing 400kV Padghe.

ITEM NO 3 : UTILIZATION OF PUMPED STORAGE STATIONS INPUMPING MODE DURING OFF-PEAK HOURS

Background: With growing self-sufficiency in the Western Regional grid, the

peak energy shortage in WR have reduced. However, it is observed that the

difference between the demand met during off-peak and peak hours has

increased. On normal days the difference is around 12000 MW which may

further increase during inclement weather / exceptional days. In order to

ensure balance between load and generation, the generation is required to be

backed down during off-peak hours and picked up during peaking hours. With

the pressure to maintain uninterrupted power supply to the customers along

with rising penetration of Renewable Energy Sources in the Grid, the need for

flexible generation (load-following, fast ramp-down, fast ramping up) would

accentuate further. These emerging challenges in grid operation call for

enhancing the flexibility of existing fleet of conventional generation and also

exploit the available facilities for energy storage and spinning reserve in the

form of Pumped Storage hydro stations.

Operation of available capacity of Pumped Storage hydro plants in pumping

mode would provide the following advantages as elaborated in the CBIP

Publication No. 265 titled “Pumped Storage in India” (Nov 1997):

a) Would enable storage of electrical energy into potential energy during

off-peak hours for utilization during peak hours


b) Provides a dynamic load during off-peak hours and thus helps in

reducing difference between Maximum and Minimum Load in the

system

c) Limits the quantum of variation in despatch schedule of thermal

stations, thus would help in enhancing efficiency of thermal stations

d) Would provide spinning reserve in the grid due to its flexibility to quickly

change over from motoring mode to generation mode

e) Would help in voltage and power factor correction

f) Improved System Reliability

The CEA report on “Large Scale Grid Integration of Renewable Energy

Sources- Way Forward” issued in November 2013 also emphasizes the need

for exploitation of pumped storage hydro stations. The report lists various

existing and envisaged PSP schemes in all the States.

The status of pumped storage hydro capacity in Western Region is as under:

Station Capacity StatePumpedStoragecommissioned

8 Kadana-II 2x60 Gujarat Yes YesVibration problems

are beinginvestigated.


Envisaged PSP schemes:Maharashtra:Koyna left bank (2x40 MW), Malsej Ghat (700 MW) and Humbarli

400 MW)

Madhya Pradesh: Mara (1100 MW) and Binauda (2250 MW) : No information

from MP whether these project exist as indicated in 468th OCC.

Apart from utilization of the existing stations in pumping mode there is a need

to expedite the commissioning of envisaged PSP schemes in the region.

28th WRPC/TCC Discussion:

During the discussion, CE,SLDC,GETCO pointed out that they are following

the matter at Kadana HPS. Vibration problems are being faced when the same

was operated earlier in PSP. The matter has been taken up with their Genco.

Also telemetry facility is available. They shall report the progress in OCC.

The detailed report for exploration PSP of KHPS submitted by Gujarat is

attached at Annexure -3

In case of Bhivpuri, Head(PSCC),TPC pointed that they are not having

pumped storage. In case of Bhira, the plant operates for more than 10 hrs a

day in generator mode. Hence even if water is pumped back it can be utilised

in off peak hours only. There are commercial mechanisms also that requires to

be addressed. Also water levels are quite sufficient and they feel PSP at Bhira

is not needed..

In case of Maharashtra, CE,SLDC,Kalwa informed that Paithon and Ghatghar

are being operated in Pumped storage mode. Regarding PSP at Ujni facility

exists, but due to commercial reasons it is not operated in PSP mode.

In case of SSP, Member, NCA informed that Garudeshwar reservoir is being

constructed in about 18 months time. With that the SSP RBPH machines can

be operated in Pumped storage mode. However this being a shared project,

the beneficiaries shall have to agree on the usage of pumped storage mode of

operation. Initially all had agreed for PSP operation, however MP later on

backed out due to commercial reasons. Presently in principle Gujarat has


agreed. But MP and Maharashtra have expressed certain reservations. These

matter is being discussed in NCA forum.

Director(Comml) MPPMCL informed that commercial problems are envisaged

due to PSP for which MP had backed out.

Director(Opn), MSEDCL informed that the commercial implications of PSP at

SSP is not known. Hence they cannot comment in this forum. However they

are willing to discuss the issue and have a relook on the situation, if need be.

MS WRPC pointed out that commercial aspects of pumping cannot be studied

in isolation, but also requires to be studied along with necessary DSM charges

paid by the utility at the time of pumping. It would certainly reduce the DSM

charges along with capping in off peak hours, nullifying the commercial impact

of pumping up the water. It may be even be economical to use PSP in off peak

hours. Hence commercial aspects of such operation should be studied

CE,SLDC GETCO stated that commercial issues and sharing of charges of

PSP in Gujarat Discoms were discussed internally and the mechanism of how

it could be shared may be also brought to the notice of all when PSP is studied

in detail.

Member Secretary, WRPC suggested that NCA may list all the difficulties

mentioned and bring out a White Paper and discuss the same in a separate

meeting. Similarly commercial aspects of PSP may also be discussed in that

meeting for all the above units with PSP feasibility.

Subsequently the matter was discussed in 56th PSC of NCA wherein it was

intimated by SSCAC that the probable completion date for work of

Garudeshwar reservoir is 03.11.2017 and PSS will be operational probably

in Janury-2018. It was agreed that a white paper on the PSS operation at

SSP will be finalised after taking into account various possible situations

which may arise in real time and will be discussed in the next PSC of

NCA. After incorporating the comments and view on the paper the same shall


be forwarded to WRPC.

TCC: The updated status of Pumped storage facilities existing is alreadygiven in the above table. NCA representative informed that white paper is

under preparation and shall be put up first to NCA Power sub-committee

meeting. GETCO representative informed that SLDC had visited Kadana and

there were some vibration problems that are being investigated. GETCO shall

revert once these problems are resolved.

Regarding Envisaged PSP at Mahagenco representative Koyna left Bank(2 x

40 MW), Humbarli these are not planned. Similarly in MP for Mara (1100 MW)

and Binauda (2250 MW) these projects as well as PSP is not planned. It

appears that these details for envisaged PSP were from planning perspective.

Hence the same were deleted from discussion till further development.

MS WRPC concluded that existing (and working as per requirement )Pumped Storage Plants are at Paithan and Bhira. At Kadana PSPvibration problems needs to be addressed. For NCA white paper shallbe discussed in NCA Power sub committee and then will be put up toWRPC.

WRPC noted.

ITEM No.4: SCHEDULING OF SOLAR POWER THROUGH INTERSTATEBILATERAL TRANSACTION

4.1. Back ground: In the 69th CCM CE SLDC Gujarat had informed that the

Inter state bilateral transaction for sale of power from M/s. Jaydeep Cotton

Fiber Pvt. Ltd. (JCFPL) to Goa under Short Term Open Access has

commenced from 28.08.2014 and elaborated the various issues w.r.t

scheduling of solar power in their letter Gujsldc/SCH/F-12/132 and suggested

replacing Schedule with actual generation.

The Committee felt that the scheduling on the above suggestion of

SLDC Gujarat can only be done if Hon’ble CERC gives directions aligned

with the suggestion

4.2. CE SLDC Gujarat vide their letter GETCO/SLDC/4501 dated


23.05.2015 informed that the Interstate bilateral transaction for sale of power

from M/s Jaydeep cotton fibre Pvt Ltd (JCFPL) to Goa is through NVVN, and

prior to scheduling of the said power under STOA WRLDC has conveyed to

Gujarat SLDC as under for M/s JCFPL

1. No POC charges and losses for solar power for CTU system.

2. If there is no UI/DSM for solar generation in the state of Gujarat, the

same may be taken care at their end.

3. WRLDC shall not carry out any post facto revision by making SG=AG.

Two more solar generators M/s Gujarat State ElectricityLtd and M/s Gujarat Power Corporation Ltd, both having10MW installed capacity of Solar Power have commenced thesale of solar power under Inter State Bilateral transaction toGRIDCO, Odhisa through SECI wef 24.3.15. In total three solarplants are selling about 20-22 MW p o we r under InterstateBilateral Transaction. In f u t u r e number of solar and windgenerators may come up for such transactions. Since thecommercial mechanism under RRF is suspended, theimpl icat ions for DSM charges on the State due to deviation cannotbe settled. Hence, the actual generation be treated as schedules for suchgenerators.

The above was discussed again in the 70th CCM, since SLDCs arereceiving application for solar power inter-State transactions. The sub-Committee felt that in view of suspension of the commercial mechanismunder RRF regulations and the provisions of the CERC regulations invogue, it would not be possible to post facto revise the schedules to theactual generation in case of the solar power plants and therefore theStates may take up the matter with CERC for further directions.

TCC:Member Secretary informed that cases of inter-state solar transactions havebeen processed in WR. He observed that with the RRF mechanism beingsuspended, the state where the solar generation is located (and passing thetransaction to another state), is unnecessarily suffering the DSM charges. Herequested that a discussion on whether it is possible to make the ScheduledGeneration equal to Actual Generation for solar bilateral transactions in WRmay be taken.


TCC members discussed the issue in length. From the discussion followingpoints merited the taking of the SG=AG.

1) The state where solar generation is located unnecessarily faces DSMcharges.

2) RRF mechanism is suspended and there is no role at present forRenewables to limit their deviation. Till such time making SG=AG forSolar bilateral inter-state transactions would be desirable.

3) In case of solar the deviations are much less than wind and so can betaken up for SG=AG.

4) GETCO informed that in GETCO similar practice is adopted for intra-state solar. Same should be extended on Regional basis

5) In case the transaction is such that WR is receiving Region (solar powerfrom other region) unless the sending region changes the SG=AG thesame cannot be done by WR alone. Hence uniformity is not possible.MS, WRPC agreed to take up the matter in NPC / other RPCs for theirstands.

6) Unless the Hon’ble CERC decides on the RRF, ancillary services etc,the deviations for all renewable cannot be fully addressed.

WRPC: During the WRPC meeting, MS WRPC informed the outcome of the

TCC. The WRPC discussed the issue. GM WRLDC opined that In the absence

of RRF mechanism by Hon’ble CERC, existing IEGC provisions does not

allow making SG=AG of a RE generator which is embedded in the State and

selling power outside the state. Besides the present RE transactions are not

only inter state but also inter regional in nature. Under such circumstances

RLDC opined it will be difficult take any decision of making SG=AG only in

WR for which no regulatory provisions exist.

WRPC observed that since the implementing of SG=AG for solar transactions

cannot be implemented by WR alone, there would be a need for uniformity with

the other regions. Hence WR also cannot unilaterally follow for transactions

within WR as uniformity would be lost( example For within region SG=AG and

inter-regional there would be no SG=AG).

MS WRPC suggested that he shall take with his counterparts in other regions

and revert in the next meeting.

WRPC agreed to MS,WRPC’s suggestion.


ITEM No.5: SCHEDULING OF 10 MW ALLOCATION OF POWER TOBARC FACILITIES (TAPS 3 &4) FROM NPCIL TAPS 3&4.

Background: WRLDC vide letter WRLDC/MO-II/1797/2015/310 dated

08.04.2015 & 27.01.2015 have informed that BARC facilities have

disconnected from MSEDCL system. Since, BARC facility is no more a

consumer of MSEDCL, therefore WRLDC vide above letters have

requested to convene a meeting to resolve the issues involved in

scheduling of power from TAPS-3&4 to BARC facilities. Accordingly a

meeting to resolve issues involved in scheduling of 10MW allocation of

power to BARC facilities (TAPS-3&4) from NPCIL TAPS 3 & 4, was held on

28.04.2015 at WRPC Mumbai.

The issues discussed were as follows;

1. Allocation of 10MW was made from NPCIL TAPS 3 & 4 to BARC facilities

(TAPS-3&4) vide letter. WRPC/Comml-I/3/Alloc/2014/7872 dated

22.08.2014 to be effective w.e.f. 00:00hrs of 23.08.2014, as per MoP letter

No.3/44/2014-OM dated 20.08.2014.

2. Scheduling of BARC facilities commenced w.e.f. 00:00hrs of 23.08.2014,

treating BARC facilities as embedded entity of Maharashtra.

3. Disconnection of BARC facility from MSEDCL : As per NPCIL letter dtd

15.01.2015, they had disconnected the supply from MSEDCL w.e.f.

17.10.2014. However MSEDCL, representative informed that they would

confirm whether BARC Facilities supply from MSEDCL has been

permanently disconnected and they do not have any objection treating

BARC facilities as regional entity.

4. Status of BARC scheduling : It was informed that since scheduling of

BARC Facility is being done as an embedded entity of Maharashtra, the

DSM and other liabilities are with Maharashtra and would continue with

Maharashtra till it is treated as embedded entity.

GM WRLDC informed that BARC is being treated as an embedded entity

and invited suggestions, whether to continue treating BARC as embedded


entity or start treating BARC facilities as regional entity in light of above

communication received from BARC facilities.

5. BARC facilities representative informed that they have not applied for

open access with MSEDCL and MSETCL. SLDC MSETCL, Kalwa

representative informed that for treating BARC facility as embedded entity

of Maharashtra, BARC Facility has to take open access of

MSETCL/MSEDCL system for wheeling power from TAPS-3&4 to BARC

Facility through MSEDCL/MSETCL system. It was suggested that

MSEDCL, Maharashtra STU and BARC Facilities would resolve the open

access issue on priority.

6. If BARC facility desires to be treated as regional entity, BARC facility would

have to approach CTU for multi party agreement between BARC Facility,

CTU, TAPS 3&4 & TAPS 1&2 and to get MSEDCL/MSETCL NoC for the

above connectivity, since one entity can not have dual connectivity with

CTU and STU simultaneously.

7. Till the above at point 6 is resolved BARC Facility would be treated as

embedded entity of Maharashtra. After completion of the above at point 7,

BARC facility would inform WRLDC and complete all the formalities with

WRLDC required for becoming a regional entity. Thereafter the scheduling

of BARC facility as regional entity would commence at a convenient date.

8. In that case, BARC Facility would be treated as buyer and DSM would be

applicable to BARC facility from the above date as per the methodology of

scheduling adopted for buyers and beneficiaries of the nuclear stations.

In line with the above discussions BARC Facility was requested to take

appropriate action at the earliest and communicate the status. However

BARC facility has not reverted on the above issue and BARC facility is

being treated as an embedded entity of Maharashtra for scheduling and

DSM accounting purpose.

TCC:During the meeting, BARC representative informed the following status. BARCis making payment to NPCIL Taps 3&4 for the energy charges as against the


allocation. Further they are paying PGCIL transmission charges for the same.He informed that they have approached MSEDCL for NOC for gettingconnectivity with CTU. He also informed that MSEDCL meters have beendisconnected since 17.10.2014. Further they have approached CTU forconnectivity and the same is in process. He expected that these proceduralformalities shall be completed shortly.

GM, WR-2,PGCIL informed that BARC shall have to pay all necessary feesand complete the application in all respects for obtaining connectivity.

CE, SLDC, MSETCL informed that since BARC have discontinued the meterssince 17.10.2014, the 10 MW allocation to BARC shown in Maharashtra asembedded entity may be removed.

SE(Comml), WRPC clarified that the allocation of 10 MW as embedded entityin Maharashtra was done as BARC was consumer of MSEDCL because atthat time BARC was not a CTU entity, but a MSEDCL consumer. The fact thatthey are no longer consumer since 17.10.2014 was not intimated to WRPC.Also if it is not possible for BARC to accept the allocation, WRPC Secretariatwould have to take up the same with CEA/MoP. Hence reversing the allocationby WRPC is not possible post-facto.

He further informed that the REA accounts show BARC separately for energy.However In DSM BARC is shown as embedded entity of Maharashtra. HenceBARC could pay for energy charges to NPCIL and transmission charges toPGCIL for the same.

MS WRPC informed the following:1) Till BARC gets connectivity to CTU as Buyer, for the allocation period,

BARC is required to be treated as an embedded consumer of MSEDCL.MSEDCL was requested to regularise the case and BARC wasrequested to complete the necessary formalities for obtaining openaccess in Maharashtra system/ any other formalities required byMSEDCL since the date of allocation.

2) Since the discontinuation of meters at BARC end by MSEDCL from17.10.2014 has taken place, the CTU meters reading for drawl point ofMaharshtra at TAPS can be used for BARC consumption, as there is noMSEDCL meter since 17.10.2014. For this MSEDCL can obtain themeter readings from WRLDC.


3) BARC was requested to complete and regularise the case so that he istreated as embedded consumer of Maharashtra since the date ofallocation. BARC agreed to the same. MSEDCL may accordinglyregularise the case.

4) Once the embedded entity of MSEDCL status for BARC is completedand regularised, BARC may like to approach CTU, if they so desire, forconnectivity with central grid.TCC recommended the above position stated by MS WRPC.

WRPC:

WRPC noted that for the period from the date of allocation tillconnectivity with CTU, BARC has to be treated as embedded entity ofMSEDCL. WRPC agreed to TCC recommendation.

ITEM No. 6 : FUNDING FROM PSDF

Background: Member Secretary, WRPC informed that CERC vide notification

No.L-1/148/2014/CERC dated 9.6.2014 have notified CERC (PSDF)

Regulation 2014. As per these regulations the PSDF shall be maintained and

operated through the Public Account of India.

(1) PSDF shall be utilized for the following purposes:

(a) Transmission systems of strategic importance based on operational

feedback by Load Despatch Centres for relieving congestion in inter-

State transmission system (ISTS) and intra-State Transmission

Systems which are incidental to the ISTS.

(b) Installation of shunt capacitors, series compensators and other reactive

energy generators including reactive energy absorption and dynamic

reactive support like static VaR compensator (SVC) and static

synchronous compensator (STATCOM) for improvement voltage profile

in the Grid.

(c) Installation of special protection schemes, pilot and demonstrative

projects, standard protection schemes and for setting right the

discrepancies identified in the protection audits on regional basis.

(d) Renovation and Modernization (R&M) of transmission system for

relieving congestion.


(e) Any other scheme/project in furtherance of the above objectives such

as technical studies, capacity building, installation of Phasor

Measurement Unit (PMU) etc.

(2) PSDF shall also be utilized for the projects proposed by distribution utilities

in the above areas which are incidental to inter-state transmission system

and have a bearing on grid safety and security, provided that these projects

are not covered under any other scheme of the Government of India, such

as Restructured Accelerated Power Development & Reforms Programme

(RAPDRP), Rajiv Gandhi Grameen Vidyutikaran Yojana (RGGVY) /

National Electricity Fund (NEF) etc.

(3) The private sector projects shall not be eligible for assistance from PSDF.

(4) Prioritization shall be done mainly on the criteria of the schemes (i)

addressing grid security concerns; (ii) being of national importance; (iii)

being in the order of National / Multi Utility/Regional/State importance; (iv)

being inter-state in nature.

(5) The Procedure for Application, Screening, Appraisal, Monitoring, Sanction

etc. of PSDF is mentioned in the regulations.

Proposals of projects for funding through PSDF are being received by WRPC

Secretariat from constituents for recommending these projects to the Appraisal

Committee in Format A5.

He informed that Initially a few proposals were received and recommendedby the Secretariat to the Appraisal Committee are as follows;

Sr.No. Name of project Organisation

1 ADMS SLDC GETCO

2 Load Forecasting SLDC GETCO

3 Fault current limiter SLDC GETCO

4 Implementation of integratedsystem for availability based tariff,open access & MIS for SLDC,MPPTCL, Jabalpur.

SLDC MPPTCL


Since the above projects were of the nature of introduction to new technology

and help in enhancing the grid security, they were recommended by the

Secretariat to the Appraisal Committee in FormatA5.

Some then more utilities have approached the WRPC Secretariat for

recommendation of their projects to the Appraisal Committee and are given

below

CSPTCL

TCC: MS WRPC informed that many more projects would be identified by

various utilities for funding through PSDF and therefore it is proposed to form a

Committee at the regional level to recommend the projects proposed by

utilities. This Committee would go through the proposals and identify the

projects which are in line with the PSDF regulations. Further the scope is with

respect to recommend only those projects that require Form A5 certification

and are of Regional nature only.

He further suggested that for recommending these projects to the appraisal

Committee a Group comprising of MS WRPC, GM WRLDC, ED/CE (STU)

from the constituents, ED POWERGRID, ED NTPC may be formed. Here only


those projects which are of a regional nature requiring Form A5 will be

recommended based on the merits of the proposal. This also does not prevent

any state or utility from going directly to PSDF.

CE, CSEB suggested that those proposals that have already come to WRPC

may be recommended by WRPC Secretariat and this Committee may

therefore look for new proposals. However MS WRPC informed that the

special Group shall clear existing pending proposals quickly, after the WRPC

meeting.

WRPC: WRPC agreed the formation of a Group comprising of of MS WRPC,GM WRLDC, ED/CE (STU) from the constituents, ED POWERGRID, EDNTPC to scrutiny those proposals that are of regional nature requiring A5 formand recommend the same to PSDF based on the merits. For existingproposals that have already come to WRPC, a meeting may be called at theearliest after the WRPC meeting.

WRPC agreed as above.

ITEM NO. 7 REVISION OF DSM ACCOUNTS AND PAYMENT OFINTEREST THEREOF & STOA REVISIONS :

Member Secretary WRPC informed that there are two issues to be discussed

at A and B below.

A) Revision of DSM Accounts and payment of interest thereof : MS

WRPC informed that ACBIL vide their letter ACBIL/WRPC/14-15/1948 DATED

24.03.2015 have intimated that the DSM account for the week 04.11.13 to

10.11.13 was revised due to inadvertent error in calculating the injection of

ACBIL and the DSM account for the week 23.06.2014 to 29.06.2014 was

revised due to erroneous CT ratio for Bilaspur substation.

For both the DSM accounts WRLDC raised invoices on ACBIL based on the

original account and later raised revised invoices based on revised DSM

accounts. ACBIL did not make the payments as per original invoice citing that

the revised accounts/revised invoices were issued prior to due date of payment

of the original account. Further WRLDC vide their memos dated 02.05.2014

and 06.01.2014 raised invoices for interest payment against nonpayment of


dues as per original accounts. The interest is not payable by ACBIL as the

DSM accounts were corrected before the due date for payment and needs to

be returned back.

The matter was discussed in the 70th CCM and WRLDC representative

informed that the interest for outstanding amounts of pool members in the

original account is calculated after the due date of the original account. Any

subsequent revision of the original account will have a new due date, therefore

till this new due date, the interest is calculated for the pool members who have

out standing amount from the due date of the original account.

If the accounts are revised within the due date of the original account, the

sufferer pool member has to bear the interest on the out standing amount till

the due date of the revised account. Therefore they unnecessarily have to pay

the interest on the out standing amount and this adversely affects the cash

flow of small pool members due to errors non attributable to them in the

account.

WRLDC was of the view that pool members should confirm their injection/drawl

is correct and errors if any should be brought to their notice by Monday, since

the meter data is uploaded on their web site by Friday, so that the errors can

be rectified and revised data can be furnished by them to WRPC for preparing

the accounts.

Not withstanding the above the sub-Committee suggested that if the accounts

due to the above errors are revised within 5days of issuing the original account

the original a/c be suspended or the interest liability of all the pool members be

calculated as per the outstanding amount as per the revised a/c after the due

date of the revised account.

Since as per the regulations, the data for DSM account is to be furnished by

WRLDC by Friday & WRPC based on this data has to issue the DSM A/c on

Tuesday. Suspension of A/cs as suggested means delayed issuance of the

A/cs as per regulations. Further the pool member would suffer in case of errors

in a/cs which are beyond their control.

Followings are recommended by CCM;


1) If the a/c is revised within the due date of the original a/c due to errors

beyond the control of pool members, the amount payable by pool members

shall be as per the revised a/c and the due date shall be as per the revised a/c.

2) If the a/c is revised after the due date of the original a/c due to errors

beyond the control of pool members, a mechanism should be formulated such

that the interest be receivable by the pool members who have paid excess

amounts as per the original a/c than the amounts payable by such pool

members as per the revised a/c.

TCC: MS WRPC informed that in spite of best efforts there are mistakes indata processing, missing or erroneous data. This leads to mistakes in DSMaccounts that have to be corrected. The corrections could be done within thedue date or beyond the due date. When done within the due date, there is aneed to extend the permitted payment time. This is because mostgovernmental agencies require a processing time for making financialtransaction. There are two bills for the same week period within due datepayment and so old bill requires to be cancelled. In the present case pointedout by ACBIL, they had made payment as per revised bill. However since theold erroneous bill was not cancelled, WRLDC raised interest payments. Herequested a discussion on the issue.

GM, WRLDC informed that if a DSM bill is cancelled by WRPC, then only thetreatment can be restricted to current valid bill. In the ACBIL case, had WRPCcancelled its old bill, the interest part for old bill would not be claimed from M/sACBIL. M/s ACBIL pointed out that WRPC had issued two DSM bills for thesame period within the due date of the first bill. They had honoured the latestbill for the same period which was recent and within due date and hence theyare not liable to make interest payment for the old bill. TCC agreed to M/sACBIL point of view and requested, WRPC to treat the old bill cancelled.

TCC recommended that when a new bill for the same week is issued beforedue date of old bill, then the old bill should be treated as cancelled. Further thenew bill shall have new due date as per regulatory norms. GM WRLDC pointedout that this may delay the payment realisation for inter-regional transactions.But since realizing interest from an old cancelled bill in the same week withindue date is not a good practice, TCC recommended that when a revised billfor the same week is issued before due date, then the old bill should betreated as cancelled.


Regarding the second part, when a new bill for the same week is issued by

WRPC after due date, the TCC discussed the issue. However it was not

possible to suggest a solution/mechanism to the problem of interest given in

the Agenda notes. In general since these errors are random in nature and no

one is preferred, it is possible that some who suffers for a period may benefit at

some other times. Hence existing practice may be continued.

WRPC:

MS, WRPC informed the above discussions to WRPC. WRPC agreed to theTCC recommendations that when a revised bill for the same week isissued before due date, then the old bill issued should be treated ascancelled. For the revised bill the new due date shall be as per regulatorynorms (10 days presently). Accordingly the M/s ACBIL case may beprocessed.

B) STOA revisions : MS WRPC informed that ACBIL vide their above

letter have intimated that the plants of ACBIL have been granted connectivity

through 400kV D/C dedicated transmission line from ACBIL generating station

switchyard to 765/400 KV PGCIL substation Bilaspur.

The LTOA/Connectivity for the plants is as under:

1. Grant of open access for 270 MW vide PGCIL letter dated 16.03.2009

2. Grant of open access for 50 MW vide PGCIL letter dated 16.03.2009 and

27.12.2013

3. Grant of open access for 2x30 MW vide PGCIL letter dated 13.06.2013

ACBIL is scheduling the gross power from all the units under common UI pool

account and WRLDC works out the deviation w.r.t declared capacity of all units

taken together.

M/s ACBIL & SCPL applied to WRLDC for revision of STOA schedule for the

1x50 MW unit of SCPL from 24.73 MW to 0 MW due to forced outage on

27.03.2014 vide application no N23280A. WRLDC POSOCO vide their mail

dated 27.03.2014 replied that the STOA revision cannot be implemented

because the plant capacity is 50 MW and in further communications WRLDC

cited CERC provision of IEGC 2010 according to which, in case of forced

outage only generator having capacity of more than 100 MW shall only be


allowed for revision in declared capacity/schedule through concerned

SLDC/RLDC.

Therefore ACBIL is requesting to permit revision of schedule in case of forced

outage irrespective of size of generating unit as combined connectivity has

been given at Bilaspur substation.

In the 70th CCM ACBIL representative informed that the entire ACBIL & SCPL

complex is treated as a single pool member having installed capacity of more

than 100MW and therefore the revision of STOA schedule should have been

allowed due to forced outage. WRLDC representative re-iterated that the

generator is having less than 100MW capacity therefore the STOA can not be

revised as per the above stated IEGC provision. ACBIL did not accept the

above clarification of WRLDC.

Since ACBIL as a pool member & generator has a capacity greater than100MW, whether the tripping of 50MW is eligible for STOA revisions ornot requires guidance of TCC/WRPC.

TCC: Ms WRPC informed the above issue and discussions in CCM. M/sACBIL maintained that there is only one pool member of ACBIL as a generatorwith a capacity greater than 100 MW. Hence if there is tripping of their unit of50 MW they have the right to revise their schedule because they are generatorof more than 100 MW capacity..WRLDC had maintained their view that schedule revision is applicable if onlythe generator unit is having a capacity of 100 MW or. They quoted the SORand regulation and were of the opinion that STOA revisions are not permittedbecause the ACBIL generating unit is not having a capacity of 100 MW ormore.

SE(Comml),WRPC said that the sentence of the regulation isQuote ( 6.5.19 IEGC First Amendment )Notwithstanding anything contained in Regulation 6.5.18, in case offorced outage of a unit of a generating station (having generatingcapacity of 100 MW or more) and selling power under Short Term bilateraltransaction (excluding collective transactions through power exchange), thegenerator or electricity trader or any other agency selling power from the unit ofthe generating station shall immediately intimate the outage of the unit along


with the requisition for revision of schedule and estimated time of restoration ofthe unit, to SLDC/RLDC, as the case may be.UnQuote

He further opined that the sentence pertains to generating station capacity of100 MW or more and not unit size.

TCC members discussed the issue, however WRLDC maintained their viewthat it was unit size that was referred not the station capacity. Further WRLDCpointed out that if the interpretation is taken as per ACBIL stand, the STOAbilateral transactions by RE generators having capacity of 2MW onwards haveto be revised by RLDCs and SLDCs in case of tripping of such units leading toa total jeopardy of the scheduling mechanism.

WRPC:MS WRPC informed the above position. During WRPC meeting, WRLDCmaintained their stand mentioned in TCC, pertaining to the interpretation ofgenerating unit or station size. Since there was no convergence on the issue,it was left to M/s ACBIL to take the issue with the Hon’ble Commission for anyclarification.

ITEM NO 8: PROCUREMENT OF ERS SUBSTATION/SYSTEM OF400/220/33KV

Background : POWERGRID proposed for procurement of Emergency

restoration System for Substation at 400/220/33kV level to meet the contingency

arising out of natural calamities like earthquake, flood, cyclone etc. In the earlier

WRPC meetings this scheme was agreed in principle and it was suggested to

discuss this issue further in technical committee meeting and examine the

proposal. Recently, cyclones of the scale of Phailin in Odhisha and Hudhud in

Vizag caused enormous damage to Power transmission infrastructure in the

respective regions which triggered revisiting the requirement of ERS Substation

at 400/220/33kV level. The matter was discussed in TCC meeting of 28th WRPC

held on 3rd March, 2015 where TCC members agreed to the suggestion of MS,

WRPC that the earlier view taken by WRPC about three to four years ago on the

ERS substation can be relooked under the present changed scenario.


During CCM meeting held on 4.06.2015 it was recommended that the proposal

for ERS s/s be discussed first in OCC for technical details and tentative cost

estimate. So that recommendations of OCC could be put up to ensuing

TCC/WRPC ensuing meeting.

In 472nd OCC meeting held on 10.06.2015 at Ahmadabad representative from

POWERGRID, WRTS – 1, Nagpur made a presentation in brief about techno-

commercial details. Mobile substations are useful for meeting the contingencies

imposed by natural disasters like cyclone and earthquake which cause extensive

damage to the power supply network. Other than natural disasters there is

application of mobile substation in cases of terrorist attacks on the power system

assets and for temporary augmentation / reinforcement of existing power supply

network like in case of organization of big national / international level events.

Mobile substations are critical for ensuring reliability in power system network in

case of contingencies beyond the control of power system operator / system

owner.

During the meeting CE, SLDC GETCO opined that above project may involve

significant commercial involvement, therefore it would be better if is funded

through PSDF fund and minimize the burden on beneficiaries. Also, participation

of DISCOMs is essential before making any decision on procurement of the

same.

Member Secretary, WRPC suggested the by procurement of such type of mobile

Sub-station the interruption of supply hrs may be reduced.

He further informed POWERGRID to come up with more techno-economical

details in upcoming TCC/WRPC meeting regarding finalizing the modalities

involved in the procurement of mobile substations for Western Region.

Present status of availability of ERS also about pooling/utilization strategies about

existing ERS constituent wise is given below:

One ERS is available with MSETCL, no ERS is available with Gujarat, one ERS

available with MP, two 400 kV ERS available with Chattishgarh at Bhilai/Raipur,

PGCIL have four set of ERS system viz 765kV at Seoni, 400 kV at Raipur, 400


kV Dehgam, Itarsi and one at 400kV & one at 500kV level total two ERS

available with Adani.

TCC: PGCIL gave a presentation on the ERS Substation/System.

Dir(O) MSETCL stated that huge investment is involved in this project and most

of the time the assets would be lying idle. Hence there shall be no financial

burden on the beneficiaries towards procurement of the ERS system.

Representatives of MP, GUVNL and CSPDCL representatives stated that there is

an issue of portability and mobility of such a huge asset, since lot of clearances

are required to be taken for transportation of the system. The system may not

reach the desired location at appropriate time, since the area of Western Region

is huge and the benefits in real time would not be as has been envisaged. TCC

therefore recommended that the ERS system be funded through PSDF.

WRPC:

MS WRPC informed the position to WRPC. Director(O),PGCIL informed that they

are working on smaller sized ERS which are commercially viable and also

capable of supplying essential power under emergency conditions. Also they

should be easily mobile. If a viable commercial and practical proposal comes up,

PGCIL shall bring the same to WRPC.

ITEM NO 9 :

A. PROGRESS OF EMS / SCADA REPLACEMENTIn the 16th Project Review Meeting of SCDA/EMS held on 6th July, 2015,

WRLDC informed that GE SCADA LTSA would expire on 13.10.2015. and

requested to complete Alstom SCADA commissioning and testing by

30.09.2015. The site readiness has been reviewed specially for the following

location :

a) Bhopal SLDC / Sub-LDC

b) Indore sub LDC

c) Goa (Madgaon) SLDC

d) Bhilai back up SLDC


After detailed deliberation with PGCIL, It was agreed that extra efforts may be

made to complete the above sites including communication requirement by

15.08.2015. In case of extreme emergency delay, alternate arrangement for

temporary deployment of new SCADA will be made to facilitate migration to

New system.

TCC: The following position pertains to above issue was informed in TCC.

Bhopal Sub-SLDC: Representatives from MPPTCL informed that Bhopal Sub-

SLDC building would be ready by 31st Aug 2015 and suggested that

temporarily alternate arrangements would be made at existing Sub-SLDC by

installing minimum hardware and data would be made available at Jabalpur

SLDC. After Bhopal Sub-SLDC building is ready hardware would be shifted for

installation along with Sub-SLDC equipments.

Indore Sub-SLDC: Representatives from MPPTCL informed that Indore Sub-

SLDC is ready and installation is in progress.

Bhilai Backup SLDC: Representative from CSPTCL informed that air-

conditioning and LT power supply work is in progress and Bhilai Backup SLDC

building would be ready for installation by 31st Aug 2015.

Goa : In case of Goa it was expected that Goa(Madgaon) SLDC would be

ready by mid August 2015.

WRPC noted.

B. MASTER PLAN COMMUNICATION

In the 16th Project Review Meeting of SCDA/EMS held on 6th July’2015,

PGCIL requested for repeater station for Master Plan communication at

following location:

a) Pichore 132 kV for Bina-Gwalior link

b) Bijawar 132 kV for Champa – Kurukshetra line

c) Sihora 132 kV for Champa –Kurukshetra line

Requirement of repeater at above location was discussed and considering the

Grid operational requirement, the same was agreed. MP requested to provide


terminal equipment in place of repeater station whenever required. PGCIL

informed that they will explore and include as per convenience.

Representative from MP informed that the same may be taken up with MP

STU and SLDC will extend necessary assistance.

TCC:PGCIL proposal to install repeater stations at MPPTCL sub-stations was

discussed. Representative from MPPTCL informed that repeater station can be

installed at 132 KV Pichore for Bina-Gwalior link. Further he informed that at

132 KV Bijawar terminal equipment may be supplied in place of repeater

station.

Representative from MPPTCL also informed that outage of 132 KV Sihora is

very difficult for laying OPGW and requested PGCIL to suggest an alternate

location/ substation for installation of the repeater station proposed at Sihora.

Also only one pair of fiber is available.

It was recommended that PGCIL and MPPTCL would discuss the requirement

of Sihora 132 kV for Champa-Kurukshetra link.

ITEM NO. 10 : UNIFIED REAL TIME DYNAMIC STATE MEASUREMENT(URTDSM)

10.1 : REPORTING OF DATA TO STATE SLDCS

The matter of non reporting of central sector PMUs data to SLDCs was taken

up by SLDCs in URTDSM project review meetings held at WRLDC Mumbai on

13-12-2014 and 09-01-2015 in which it was principally agreed that PMUs data

of all stations falling under geographical area of the State is required to be

arranged in real time to the PDC of that SLDC. Further, representative of

LD&C POWERGRID informed that technical feasibility for additional

reporting/routing of data from Central sector PMUs need to be worked out

considering the capability of hardware and software, especially historian sizing,

storing capacity, duration etc. and assured that they shall revert back during

the next meeting.


The above was emphasised in the 28th WRPC meeting by the beneficiaries

and SLDCs. The above requirement, along with necessary hardware and

software required was in principle accepted by WRPC and PGCIL was

requested to work out the details of hardware and software requirement and

discuss the same in detail with WR constituents in the ensuing URTDSM

meeting. GM – PGCIL(HO) agreed to examine and implement the same.

In the 4th URTDSM meeting held on 6th July’2015, as per the directives ofWRPC in the 28th WRPC meeting. PGCIL representative informed thatthey have worked out the hardware and associated requirement andconfirmed that original configuration is adequate to meet the above dataflow.

TCC/WRPC noted.

10.2: URTDSM technical requirement:In the 4th URTDSM meeting during the presentation on 7th July’2015 by IIT-B,

PGCIL to a query clarified that one terminal at WRPC would be made available

and PMU data would also be available at this terminal for analysis by the

protection group of WRPC.

IIT-B gave a presentation on the analytics being developed under this project.

The analytics envisaged in the project includes On line State Estimation,

Estimation of line parameters, vulnerability analysis of relays for load

encroachment and power swings, CT/PT calibrations and Zone-III adaptive

protection.

To a query of representatives present as to whether metering core or

protection core is wired up for PMUs, IIT-B representative replied as per

POWERGRID proposal metering core is being wired up for PMU.

It was in general felt that the choice of instrumentation transformers cores

should be based on the applications/analytics being developed for the project

and for all protection purpose analytics it would always be advisable to use the

protection core of the instrument transformers since under heavy power swings

and faults persisting in Z-II/Z-III timings the metering cores would saturate and

the analytics developed for protection purpose would not give desired results.


Therefore for specialized protection analytics PMUs of protection class are

required to be wired up in PS class CT/PT cores.

Since POWERGRID was responsible for providing input they assured to

consider the above suggestion and would revert back.

TCC: The matter pertaining to the use of protection core/ PS class PMU

wherever protection analytics are to be deployed was discussed. PGCIL

representative agreed to look into the matter and revert back.

WRPC:Director(O), PGCIL queried whether protection core can be used as existing

protection cannot be sacrificed. It was informed by some members that

additional protection cores can be used. Director(O),PGCIL informed that this

position may not be true for all stations, and they shall check up on the

suggestion and revert back.

WRPC noted.

10.3: URTDSM Manpower requirement

In the 4th URTDSM meeting held on 6th July’2015, PGCIL has informed that

scheduled Program Development System ( PDS) is to be delivered during

August 1st week. The Committee discussed the requirement of dedicated

manpower for PMU technology development and deployment in SLDCs. GM,

WRLDC informed that PMU technology has immense potential in Grid

operation for improvement in system efficiency and reliability. So dedicated

man power will ensure engagement of the Engineers from all control centres

towards adoption of new technology and achieve desired benefits.

After detailed deliberation the URTDSM Committee recommended fordedicated man power of 2-3 persons in each control centres to beprovided respective utility (SLDC/RLDC).

TCC/WRPC agreed to manpower requirement. However manpowerplanning has to be arranged by concerned utilities.


10.4: URTDSM space requirement

In the 4th URTDSM meeting held on 6th July’2015, PGCIL informed the

schedule for delivery of URTDSM project materials and requested constituents

to arrange necessary space at all control centers for which constituents

agreed.

Constituents agreed to provide space as per requirement.TCC/WRPC noted.

ITEM NO. 11: TESTING OF SPS ENVISAGED FOR SR-NEW GRIDOPERATION AND 765 KV AGRA-GWALIOR LINES

11.1 : SPS ENVISAGED FOR SR-NEW GRID OPERATION :

Back ground: As per NLDC’s letter dated 11.04.2014, the backing down quantum for

generators in WR were finalized for various security threats after NEW – SR

synchronization with 765kV Raichur-Sholapur Ckt-I. The matter was further deliberated in

the 26th WRPC meeting held on 21.06.2014 and decided that as and when the signals are

extended to the newer generators, the quantum of backing down of the already

participating generators will be reduced on prorata basis. NLDC vide letter dated 07th July

2014 communicated modification in SPS in view of commercial operation of 765kV

Raichur-Solapur ckt-II. The same was circulated to all the concerned for necessary action.

Status: In the 123rd PCM, PGCIL was requested to extend the signal to Lanco at the

earliest and requested all newly participating generating stations to complete the wiring for

necessary action at their end. It was also decided that mock testing of the modified SPS

may be done by WRLDC after completion of signal extension and wiring at all generating

stations.

WRLDC representative intimated that mock testing of SPS for 765kV Raichur –Solapur D/C was done in December 2014 and signal for generation backdown wasreceived at all envisaged generating stations i.e. KSK, JPL, JPL Extension, NSPCL,BALCO, KWPCL and DB Power.

TCC/ WRPC noted.

11.2: Tripping of 765 kV Raichur – Solapur D/C on 24.05.2015: On 24.05.2015 at

around 19:13 Hrs 400 kV Chittor – Tiruvalem – I & II tripped. Subsequently at 19:19 Hrs,


HVDC Talcher – Kolar pole I & II tripped on valve cooling problem and thus the power flow

on each circuit of 765 kV Solapur – Raichur D/C touched around 1573 MWs and these line

tripped from Raichur end. It was followed by tripping of around 1750 MWs generation and

1000 MWs load shedding in SR.

In the 125th PCM, WRLDC representative intimated that during the above occurrence,

power swings were observed as seen from the PMU data of Solapur and Raichur. He

further informed that it is suspected that the lines have tripped from Raichur end due to

crossing of 1000MW for 10 secs. However the tripping of the D/C should have been

blocked when both ckts are in service. The tripping at WR end (i.e. Sholapur end) is

blocked and it needs to investigate whether the tripping for above condition is blocked at

Raichur end. This has been taken up with POWERGRID. Committee felt that during the

above occurrence, the load shedding in SR envisaged for HVDC Thalcher-Kolar SPS might

have acted correctly. However during the occurrence generators at Meenakshi(150MW),

SDS TPS (800MW), Raichur TPS(210MW) and Ramagundam-Bhadrawati Pole 1 was out

of service. This led to increase in loading on Raichur-Sholapur lines, but the load shedding

in SR was not adequate (due to combined effects of HVDC Thalchar-Kolar tripping and

Generation trippings in SR). Further it is suspected that SPS settings as per NLDC letter

dated 07.07.2014 is not revised at Raichur end(i.e. blocking of tripping for O/L when both

ckts are in service). This led to tripping of the lines from Raichur end. . Committee

requested WRLDC to take up the matter with NLDC / SRLDC / ERLDC. Further, the loads

to be shed identified for Thalchar-Kolar SPS & Raichur-Sholapur SPS should be

independent of each other.

TCC/ WRPC noted.

11.3: Tripping of 765 kV Raichur – Solapur D/C on 31.05.2015: In the 125th PCM,WRLDC representative intimated that at 16:59 hrs, 765 KV Raichur-Solapur-II tripped on

B-phase fault .At 17:00 hrs, 765 KV Raichur-Solapur-I tripped on Y-phase fault. A/R

attempted for both circuit but due to persisting fault, the lines tripped.

765 KV Raichur-Solapur-I was charged from Raichur end at 17:42 hrs and synchronized at

Solapur at 19:00 hrs. During synchronization, SPS operated and generation backing down

took place at NSPCL ( 25 MW ), JPL ( 70 MW ), KSK (40 MW ). 765 KV Raichur-Solapur-II

was restored at 19:25 hrs. At the time of synchronisation large power swings were


observed and the magnitude of Power swing was more than 3000 MW on this occasion,

which caused SPS operation.

The large power swings were observed due to improper synchronisation of the NEW & SR

grids. As seen from the PMU data, the synchronization was done at an angular difference

was around 115 degrees. The matter was discussed in PCM and it was felt that angular

difference estimated/assessed during the synchronization by WRLDC may not be around

115 degrees, since synchronization at such an angular difference would have resulted

power flows of the magnitude of phase to phase faults. However there was some problem

during synchronization which needs to be brought out by studying the incidence in great

depth by central agency like NLDC/CEA. Subsequently considering the seriousness of the

above events, WRPC vide letter dated 17.06.2015 took up the issue with CEA. NLDC

have published a report on the above events and a copy is available at WRPC web-site..

TCC: PGCIL representative intimated that tie breaker was used for Bus reactor and

during commissioning of CSD in 2014, the “synchro check OK” input to BCU was missed

out, therefore the synchronisation of the line through Tie breaker was not done by

ascertaining the “synchro check OK” during synchronisation.

WRPC: Director (O) PGCIL intimated that this was an unexpected charging situation from

tie breaker, as it is usual to do the same from Main breaker. They have already directed to

take all precautions to check the synchronisation for any tie breaker charging situation,

between two asynchronous grids, to avoid errors in future.

ITEM NO. 12:

12.1 SPS FOR AGRA-GWALIOR – MOCK TESTING OF SPS ENVISAGED FORBACKING DOWN OF GENERATION IN WR

Background: An SPS has been implemented for 765kV Bina – Gwalior – Agra D/C,

wherein when sudden reduction in import by NR on Agra-Gwalior I & II ckts by more than or

equal to 1500 MWs, 500 MWs generation back down in WR (KSTPS NTPC– 120 MWs,

VSTPS NTPC – 200 MWs & CGPL – 180 MWs) and load shedding in NR would take place.

The mock testing of SPS for 765 kV Bina – Gwalior – Agra D/C was proposed by NRPC on

24.12.2014. The mock testing of the SPS was unsuccessful and in the 124th PCM, PGCIL


representative intimated that the signals were sent to generating stations directly from Agra

S/s, under PGCIL - NR.

The mock testing of the SPS was again carried out on 30.04.2015 and the receipt of

signals at all the generating stations in WR was confirmed.

In the meeting held on 23.06.2015 at CEA New Delhi for revision of SPS settings of 765kV

Bina-Gwalior-Agra lines, it was decided that the SPS setting for triggering Load Shedding in

NR be revised from existing 1250MW to 1400MW for each circuit (i.e. 2500MW to 2800MW

for D/C). Increase in flow limit for SPS would allow import by NR upto 1400MW on each

ckt. However ATC/TTC would not be changed. This settings would be observed for some

time before revising upward and also in the light of ensuing commissioning of 765 kV

Gwalior-Jaipur Circuit.

WRPC noted.

12.2: Review of SPS for CGPL Mundra:

In view of commissioning of 400 kV Bhachau – Versana D/C the SPS was under review.

12.3: Islanding schemes for TAPS 1 & 2 and TAPS 3 & 4:

In the 124th & 125th PCM meeting, it was proposed that TAPS 1 & 2 generation be islanded

with Bhilad load and TAPS 3 & 4 be islanded with load of Boisar (MSETCL). In the 124 th

PCM, Committee reviewed the proposal and opined that units of TAPS 1 & 2 are very old

and fine control of generation is not possible. The governors of TAPS 1 & 2 are such that

the generation can either be 160 or 100 MWs. Further the radial loads at Bhilad are

variable and fine control of loads may not be possible. Therefore islanding TAPS 1 & 2 with

Bhilad load may not survive for long and even if it survives, while restoring the grid it may

be very difficult to synchronize this island with grid as both load and generation of the

island are not controllable.

Further it was felt that as the generation of TAPS 3 & 4 can be controlled, it would be better

to form an island with generation of TAPS 1, 2, 3 & 4 and loads of Bhilad and Boisar.

Committee requested TAPS 1 & 2 to take up the above proposal with higher authorities and

revert back to the PCM forum with its proposal.

TAPS 1 & 2 representative intimated that the above proposal was discussed in depth with

higher authorities. It was felt that TAPS 1, 2, 3 & 4 together as island have multiple


combinations (All Units are running, TAPS 1 under shutdown etc..,) , it would be very

difficult to implement the logic for the same.

Committee decided to drop the proposal for islanding of TAPS 1 & 2 and islandingscheme for TAPS 3&4 be formulated and requested WRLDC to prepare a draftscheme and put up the same in the next PCM.

TCC: GM WRLDC informed that they have prepared the scheme after discussion with

TAPS 1&2 and 3&4 authorities. All data for preparation of an islanding scheme exists. He

requested NPCIL to formulate any suitable islanding scheme, in case they do not wish to

implement the present scheme for Taps islanding and put up to PCM.

Since necessary data was available with NPCIL from the above discussions it was decided

that Taps1&2 and Taps3&4 may examine the schemes and revert to PCM forum.

WRPC:

MS WRPC informed the above position. WRPC requested NPCIL to look into the islanding

schemes and suggest a suitable islanding scheme. Necessary regulatory clearances if any,

may also be obtained. NPCIL agreed to revert back in PCM.

ITEM NO. 13 : DEVIATION SETTLEMENT MECHANISM AND RELATEDMATTERS (FIRST AMENDMENT) REGULATIONS, 2014 DATED 18TH

DECEMBER’ 2014Background:

In the 28th WRPC meeting MD, MSETCL pointed out that the bigger states like

Maharashtra, MP, Gujarat etc face a lot of practical difficulties in restricting the

deviations as per the provisions of the DSM regulations and amendments thereto.

However the representations with the Hon’ble CERC have been made on individual

basis (as only MP has approached the Commission). He further suggested that if

difficulties are experienced in implementing the restrictions of deviations as per

DSM regulations during operation by almost all the States of the region, then as a

region it is necessary to represent the case and also point out acceptable solutions

before the Commission or appropriate redressal forum. He pointed out the following


difficulties are being faced by Maharashtra and other States in restricting deviations

within limits:

1) Impact of Renewable Energy: The renewable energy particularly wind faces

a lot of uncertainties. The quantum of wind has gone up in Maharashtra. These

variations are far above 150 MW limits prescribed. The RRF mechanism is

suspended. In these conditions, the State is unnecessarily burdened with DSM

penalties.

2) Failure of Communication links: In January 2015, there were instances

when the major communication links failed. Under these conditions, the State was

asked to back down generation. With frequency being low, the DSM penalties were

very high, as it turned out from the energy meter readings that the State was not

actually underdrawing as seen from the SCADA in absence of links, but was

overdrawing. There should be provisions in the DSM to mitigate penalties in such

cases where state is asked by WRLDC to backdown and links are not fully present.

3) Need for Redundancy in links: There is a need to increase the redundancy

in communication links in a phased manner so that the above point does not repeat

and cause financial implications.

4) Too small margins: Apart from the RRF factor, the margin for deviation of

150 MW for States with demands ranging from 10000 to 20000MW and central

shares around 4000 MW is too small to be within limit and seriously requires to be

enhanced.

5) Infirm power: New generating units under infirm power also cause

deviations.

WRPC in the 28th meeting accepted the suggestions of MD MSETCL and

recommended for formation a group comprising of representatives from all states

and study the problems faced during the DSM regime and suggest the solutions in

the next WRPC meeting. It is necessary to represent the case as a region and also

point out acceptable solutions. It was decided that the Scope of the Group would be

to study the operational challenges mentioned above and other related issues if

any, which are commonly affecting the states in WR and suggest acceptable

solutions and put up to the next WRPC meeting so that the matter may be put up to

the Commission as a Region, if required.

It was decided that the group shall be as follows:


1) All CE, State SLDCs

2) NTPC

3) All CE, Discom / Holding company if required

4) Any other member as required during discussions

CE, SLDC MSETCL shall be convenor.

A meeting was convened by CE SLDC Maharashtra at SLDC Kalwa on 22.04.2015.

CE SLDC may give presentation on the outcome of the meeting.

TCC: CE, SLDC gave a presentation on the Group’s findings. The same is given atAnnex 13.

WRPC: MS WRPC informed the details of the presentation. It was earlier decidedthat a joint petition shall be filed by big states who are facing problems in DSMimplementation, with Maharashtra taking a lead. Others had agreed to join thepetition. MPPMCL had already filed the petition with the Hon’ble CERC on the sameissue. However other DISCOM in MP may join, barring of MPPMCL. It was agreedthat Maharashtra Discom can file a joint petition with CERC. Financial charges shallbe shared by the concerned utilitiesWRPC agreed.

14.2: CERC (Sharing of Inter State Transmission Charges & Losses)-3rdAmendment Regulations, 2015, dt 1st April 2015


Hon’ble CERC has notified 3rd amendment regulations of Sharing of Interstate

Transmission Charges & losses dated 01.04.2015

Brief on the Amendment is given below

1. Terms deleted from all sections of the Regulation:

Peak and Off peak hours scenarios.

Network Truncation

Uniform Charging method

2. Application period ie ‘period of application of these charges’ is now for

3months duration. (eg. Apr-Jun, July –Sep, Oct-Dec, Jan-Mar.)

3. Approved injection (MW)-( for an Application Period) is now defined as the

maximum injection made during the corresponding application period for the last

3yrs.

4. Approved withdrawal (MW)(for an Application Period) is now defined as the

actual peak met during corresponding application period of last 3yrs.

5. DIC :(User of any segment of ISTS viz generator, STU/SEB, Load) Now it also

includes any intra state entity who has obtained MTOA or LTA to ISTS and are

connected to either STU or ISTS or both .

6. In addition to injection/withdrawal PoC, two more new charges have been

introduced.

(1) HVDC Charges and

(2) Reliability Support Charge

7. Additional norms are defined for data submission to Implementing Agency (IA)

Nodal generation data (forecast based) by the DICs (for an application

period)Forecast demand data by the DICs (for an application period)For a given

application period the IA would compute the Approved Injection / Withdrawal

based on last 3 yrs. actual fig. & same will be validated by the VC Difference b/w

the fig. given by the DIC & those computed by IA have to be explained reasonably

by the DIC Mis-declaration by a DIC ( beyond +/- 20% ) for 2 consecutive quarters

– Treated as Gaming & to be reported to CERC.

8. ‘Network truncation’ is no more allowed and Hybrid methodology shall be

applied by the IA on the Basic network to determine Transmission charges

(Injection & Withdrawal PoC rate) and Loss allocation factor (LAF).


9. There shall be 9 slab rates for PoC rate (in Rs./MW/Month) as well as PoC

Loss (in %).

10.Recovery of transmission (YTC) based on both Hybrid and Uniform charges

stands amended.

Recovery of YTC will now be done in 3 parts PoC Charges ( Calculated based on

hybrid methodology) Reliability support charges ( RSC to recover 10% of YTC)

HVDC charges 10% of YTC shall be through Reliability Support Charge sharing

methodology. This charge shall be determined separately and shall not mixed with

Zonal PoC rates.

11.Now onwards losses also shall be apportioned to each DIC through Hybrid

methodology only.

Earlier 50% was through Hybrid and 50% through uniform loss allocation

mechanism Now there will be 9 slabs of Loss ( 4 steps above & 4 steps below the

average loss %) Step size = 0.25 % ( Min Loss = 0%)Slabs to be reviewed by

CERC after 2 years.

Any ISGS connected to 400kV ISTS system ( including those connected to ISTS

& STU) shall be treated as a separate Zone.

12.Merchant Power Plant: New definition introduced Whose tariff is neither

determined as per sec-62 or sec-63 of the Act & who sells entire capacity in the

open market. For Merchant power plants connected to ISTS with zero LTA or part

LTA, injection considered in Base case or LTA which ever is higher shall be

considered to arrive at PoC injection rate.

13. In case commissioning (CoD) of a generating unit is delayed, the generator

shall be liable to pay withdrawal charges corresponding to the LTA granted &

withdrawal charges shall be @ average withdrawal PoC rate of the target region.

14.Before CoD & Commencement of LTA when a Generating station draws start-

up power or injects infirm power its liable to payWithdrawal PoC charge for drawal

of start-up power (as per actual quantum of W/D) Injection PoC charge for infirm

injection (as per actual quantum of injection. )(The amount collected through this

shall be adjusted against YTC for next application period)

voltages in the range of 421 kV to 440 kV were noted at Indore, Itarsi, Karad,

Dhule, Kasor, Bhilai, Jetpur, Bina, Gwalior, Nagda and Khandwa substations.

To contain high voltages WRLDC resorted to opening of lightly loaded EHV

lines on certain days. The detail of voltages at important 400 kV and 765 kV

sub-stations during the period of during February 2015 to June 2015 is placed

at Annexure- 21.2. In order to control incidences of high voltages during low

ITEM.NO.25: WRPC MEMBERSHIP FOR RATTANINDIA POWER LIMITED

MS WRPC informed that M/s RattanIndia Power Limited vide letter

RPL/WRPC/15-16/006 dated 09th April, 2015(copy enclosed at Annexure-25)

have requested for inclusion of RattanIndia Power Limited as a member of

WRPC.

Government of India, under the provision of Section 2 (55) of the Electricity Act

2003 vide its resolution F. No.23/1/2004-R&R dated 25th May 2005,

amendment dated 29th Nov.2005 and subsequent amendment dated 9th May

2008 has established the WRPC. As per the resolution, a representative from

every generating company which has established a generating station more

than 1000MW in Western Region shall qualify to become member of WRPC.


The RattanIndia Power Ltd(RPL), , Maharashtra successfully commissioned

the 5 units of generating capacity 270 MW each at Amaravati and one unit of

capacity 270 MW at Nasik(total 1620MW) w.e.f. 13.03.2015.

Accordingly, RattanIndia Power Ltd(RPL). may be included as a

member of WRPC representing the Generating companies with more than

1000 MW generation capacity from the year 2015-16 onwards.

TCC/WRPC: MS WRPC informed that M/s RattanIndia Ltd qualifies for

membership. Generally the practice followed in WR, is to get the approval from

Chairperson, WRPC for new members who qualify for membership. The

present Chairperson WRPC desired that the membership should be approved

by WRPC after the qualifications of criteria is checked by the WRPC

Secretariat. Hence MS WRPC brought the issue for the notice of WRPC.

Since M/s RattanIndia Ltd qualifies to be a member , the membership wasapproved by WRPC for 2015-16 onwards.

Item No SA-1: CONFIRMATION OF THE MINUTES OF THE 28TH MEETING OFWRP COMMITTEE

This is already covered in Item No 1.

ITEM No.SA-2 : INSTALLATION OF POLYMER INSULATORS ON NEWTRANSMISSION LINESGM(Asset Management), PGCIL Gudgaon vide letter dated 13.07.2015

intimated that number of trippings of transmission lines in Western Region

take place due to flashover across porcelain/antifog disc type insulators due to

environmental pollution which is dynamically changing over a period of time.

Considering high number of trippings due to flashover of insulator in Northern

region, NRPC during its 30th meeting held on 28th Feb, 2014 approved that “ in

future all new transmission lines in plain areas would be built with polymer

insulators only and also existing anti-fog insulators would be replaced with

polymer insulators in phased manner” (Extract enclosed as Annexure-I)


In line with above, it is suggested that members may deliberate adoption of

suitable policy for Western Region for installation of polymer insulators in

existing as well as new lines.

TCC : Beneficiaries were of the view that the above work may be taken up by

PGCIL through their own funding or under O&M. PGCIL agreed to do it.

However deemed availability for outage during the replacement may be given.

MPPMCL informed that this part of the agenda had come late and requires his

management approval. GETCO informed that as per their state regulation, this

type of work is under renovation and moderation and the utility gets deemed

availability. Position as per CERC regulation may be taken by WRPC.

WRPC : Director (O) stressed that the above replacement would improve the

reliability which would benefit the beneficiaries. He informed that in NR the

replacement has resulted in no fog related tripping.

Regarding the outages for planning, OCC shall co-ordinate the same.

Regarding the deemed availability PGCIL requested to consider this for system

improvement category. Also if availability increases beyond 99.75% due to the

above being considered as deemed availability, they are willing to restrict the

same to 99.75%

MS WRPC informed that as per regulatory provisions the availability shall be

given to the extent under system improvement, after confirming the practices

followed in other regions.

WRPC noted.

ITEM No.SA-3 : ALLOCATION OF URS FROM CGPL UNITS:

CE, SLDC Gujarat intimated that at present, all the Central and State

generating stations are governed by the tariff regulations of the respective

commissions. Their beneficiaries are allowed to change their schedule for the

un-requisitioned quantum of power from one beneficiary (ies) to another

beneficiary (ies) of the same power station on the requisition by any of these

beneficiaries through the provision provided in the IEGC. In case the original


beneficiary requests back for its share of power, then its schedule and

schedule of beneficiary who had availed URS power would be revised as per

the provisions of IEGC.

However, it is observed that the URS of NR constituents in CGPL is not being

scheduled to Gujarat in line with the above procedure when there was acute

shortage of power. The theme behind the reallocation of URS is to utilize

resources in the best possible / in an optimum way.

The issue of allocation of URS from CGPL in line with other Central Sector

NTPC units was discussed in the 27th WRPC meeting held at Bhopal on

22.11.2014. The Chairperson WRPC informed that though the petition of URS

with Sasan will take its time to be resolved by the Hon’ble Commission, there

are numerous instances where URS can be availed with these two existing

and working UMPPs in the Western Region for which we must consider doing

something in the interim period.

The matter was again discussed in the 69th CCM held on 23.01.2015;

however, GM, WRLDC stated that they don’t agree for scheduling UMPP

power under URS and stated that the beneficiaries have to avail STOA for the

same. This is quite illogical considering the fact that for availing the URS

power, why at all any beneficiary requests the same on STOA and pay undue

transmission charges.

The matter was again discussed in the 28th WRPC meeting. It was felt that

due to the stand taken by WRLDC, it would be necessary to wait for the order

in Sasan URS case. However, the order in the Sasan URS case is yet to come

and pending since long. And due to want of the order in the said matter, it

would not be appropriate to hold the scheduling of URS from CGPL as

represented by all the procurers.

TCC: Beneficiaries agreed for URS from CGPL and requested WRLDC tocommence scheduling URS power.

WRPC: MS WRPC informed that while WR beneficiaries are in agreement for

URS from CGPL, however since CGPL has NR side beneficiaries, he shall


take up with the NR counterpart and upon considering their views URS of

CGPL can be started.

WRPC agreed.

ITEM NO. SA-4 :SCHEMES APPROVED IN THE 38TH SCM OF WR HELDON 17.07.15 AT NEW DELHI:

POWERGRID vide email dated 21.07.2015 have requested to include

following two items approved in the 38th SCM held on 17.07.2015, pending

release of MoM of 38th SCM for timely implementation.

SA-4.1 : LAYING OF CABLE IN DGEN-VADODARA 400 KV D/C LINE ATDGEN END :

Regarding laying of cable in DGEN-Vadodara 400 kV D/C line at DGEN end,

GETCO was of the view that the scheme cannot be awarded as due diligence

was not done as per procedure to look for all options. GETCO has not given go

ahead to CTU for implementation of 400 kV, 125 MVAR bus reactor at 765/400

kV Vadodara substation to compensate reactive power due to proposed laying

of 3 km cable in DGEN- Vadodara 400 kV D/C line at DGEN end.

CEA vide letter dated 07.04.2015 has furnished clarifications to GETCO giving

details of the deliberations done among CEA, CTU, GIDC and Torrent Energy

Limited to arrive at the decision for provision of cable in DGEN- Vadodara 400

kV D/C line. The matter was further discussed in the 38th SCM and approved.

As the same was now approved in SCM, the matter is now closed.

TCC/WRPC noted.

SA-4.2 : MODIFICATION IN TRANSFORMATION CAPACITY AT ITARSI S/S :

In the 37th Standing Committee Meeting on Power System Planning of WR

held on 05.9.2014, MPPTCL proposal of an additional 1x315 MVA, 400/220kV

transformer along with two nos. of 220 kV bays at Itarsi (PG) 400/220 kV S/s,

to ensure the reliability of supply to 220 kV substations around Itarsi and Betul

area was agreed.


POWER GRID vide their letter no. C/CTU/W/Itarsi dated 23.03.2015 has

proposed that rating of additional (2nd ) ICT to be installed at Itrasi be revised

to 500MVA instead of 315MVA, as the cost of 400/220kV ICT of 500MVA and

315MVA is generally of same order.

The above was further discussed in the 38th SCM and the proposal of 500MVA

ICT instead of 315 MVA additional (2nd) ICT to be installed at Itrasi, was

approved.

TCC/WRPC noted.

ITEM No. 26: ANY OTHER ITEM

ITEM No. 27: DATE AND VENUE OF NEXT WRPC MEETING:

MS WRPC informed that next WRPC meeting hosting is to be hosted by Jindal

Power somewhere in November 2015 preferably at Bhubaneshwar.

Annexure -3

Report on pump mode operation of Kadana Hydro units

In 467th OCC meeting of WRPC held on 16.01.15 at WRPC, Mumbai, it was decided that

SLDC-Gujarat would update latest status regarding capability of pump mode operation of

hydro units of Kadana Hydro plant (4 x 60 MW). Also, the General Manager, WRLDC vide

letter No. WRLDC/SO/137 dated 05.02.15 informed that CEA report titled “Large Scale

Grid Integration of Renewable Energy Sources - Way Forward” issued in Nov-13 says

that 4 x 60 MW units of Kadana Hydro plant Stage - 1 & 2 in Gujarat are capable of

operating in pumped storage mode. The report indicates that the facility is presently not

working and it recommends as under:

“The vibration problem in Kadana PSP (240 MW) also needs to be resolved”

Presently, the installed capacity of wind generation is 3500 MW. Many times, it is

observed that the wind generation during night hours remains on higher side and the

system demand remains on lower side. In such conditions, there is a heavy under drawl

during night hours which is penalized under recent Deviation Settlement regulation of

Hon’ble CERC. Also, the system faces high voltage issues many times. It leads to tripping

of 400 KV lines connected to Wanakbori Thermal Power Station. The generation schedule

from Kadana Hydro units is based on irrigation requirement. During peak hous in winter

and summer season, the KHPS generation is limited to only one unit. In such conditions,

the costly gas generation has been scheduled in open cycle for meeting peak demand.

Looking to all these, the capability of pump mode operation will play vital role in power

system operation.

To know updated status and to explore feasibility of Kadana units in pump mode

operation, Shri. D. B. Joshi, SE (OP), SLDC, Shri. B. M. Shah, DE, SLDC and Shri K. G.

Patel, DE, Corporate Office, GSECL visited Kadana Hydro plant on 21.02.15. The team

verified past records of pump mode operation also. The chronological summaries of past

records are as under:

A meeting was held on 30.08.03 with M/s. BHEL representative. In the meeting, it was

decided that M/s. BHEL would send the team to ensure readiness of all the units for pump

mode operation. If required, they would call experts from M/s. SKODA for overall

of 3

supervision. Also, M/s. BHEL would identify the spares requirement. They would check

and ensure control, instrumentation and protection requirement. Thereafter,

commissioning of the pump mode operation would be carried out. Accordingly, the joint

inspection of all four units had been carried out in the month of Sept-03. They had listed

out further works to be carried out before commissioning of pump mode operation.

Various works / activities had been performed jointly by the team of M/s. BHEL, M/s.

SKODA and GEB between 20.02.04 and 08.04.04. They had updated the status

regarding commissioning and operational status of pump mode operation to GEB

management on 09.04.04.

In their observation, it was mentioned that the trial of all four machines under pump mode

operation was taken. Unit No. 3 & 4 tripped on turbine guide bearing temperature high. In

the meeting, GEB requested M/s. BHEL to intimate the vibration limit for operation of

pump mode. Also, it was noted that acceptance of commissioning of pump mode

operation would be considered successful after seven Nos. of successful trials through

auto sequence from control room. At least one trial should be more than 05 hours and

rest for minimum 03 hours of continuous run. It was also mentioned that it is desirable to

maintain TRC level between 78 meters to 81.5 meters. It was mentioned that there was a

considerable heating of reactors and therefore, enclosure works need to be done. There

was structural vibration observed in all units at the generator floor and to be got analyzed

at appropriate level. Also, it was mentioned that the reliability and consistency of safe

operation in pump mode was yet to be established and high level of vibration in pump

mode operation was to be rectified for prolonged use in safe condition.

On 24.06.04, the Officer on Special Duty at KHPS reported that they may run pump mode

operation of any unit at any time without support of M/s. BHEL. As per the record of pump

mode operation of all four units, the maximum vibration horizontal at turbine guide bearing

for Unit No. 3 was on higher side. M/s. BHEL had recommended that maximum 50 micron

vibration shall be allowed at bearing (Horizontal).

On 07.03.06, the Engineer-In-Charge, KHPS informed that there are certain constraints /

limitations in operating units on pump mode.

Vibrations of the order of 12 to 15 microns are observed at power dam during

pump mode operation of Unit No. 1 & 2.

of 3

Unit No. 3 tripped frequently on rotor earth fault. Also, 6 Nos. of slip rings insulated

bolts were found puncture.

When the machine was running in pump mode, initially, 16000 Amp eddy current in

reactor was developed and it was to be controlled as per the guidelines of SKODA

engineers.

Since October - 2005, no unit of KHPS was operated on pump mode. Hence, it is utmost

necessary to carry out inspection of units one by one in presence of OEM to put pump

mode operation at KHPS in service. The recommendations of OEM regarding spares /

modifications / rectifications shall be taken into account to reestablish pump mode

operation. Also, study shall be carried out to access allowable vibration limit of Dam

structure as well as vibration (horizontal) at turbine guide bearing of each unit. The matter

shall be taken up with the irrigation authority to maintain down stream reservoir level

situated at Dolatpur. The comprehensive proposal shall be placed in PSDF by GSECL

Corporate Office. If requires.

It was discussed during 468th OCC meeting of WRPC held on 16.02.15 that 2 x 125 MW

units at Ghatghar Hydro power station in Maharashtra are capable of operating in pump

mode and are being operated in pump mode. Therefore, it is suggested that a team of

experts from GSECL shall visit Ghatghar HPS and have a detailed deliberation with the

authorities there so that they can explore the feasibilities of sustainable operation of

KHPS units on pump mode at the earliest.

1.0 Background Hon’ble CERC had issued an order on regulation for Deviation Settlement Mechanism (DSM) 06th Jan, 2014. The DSM mechanism is in place of Unscheduled Interchange (UI) Regulation. The DSM regulation is implemented w. e. f. 17th Feb, 2014. Before implementation of DSM, Hon’ble CERC had called comments and suggestions all constituents. Accordingly most of the stack holders has represented to Hon’ble CERC regarding difficulties envisaged during actual implementation of mechanism due to volume cap of +/- 150 MW on deviation. Managing Director, GETCO has pointed out their views to Central Electricity Authority and Hon’ble CERC on implementation of DSM on 12th Feb, 2014 i.e. before actual implementation of mechanism. The views pointed out in above communication are representative views of all states in western Region. The letter is placed at Annexure ”A” Further, Managing Director, GETCO has again pointed out their view and operational experiences of DSM Mechanism to The Chairman, CERC on 10th Nov 2014, reiterating the same views on DSM mechanism. The letter is placed at Annexure ”B” Madhya Pradesh Power Management Company Limited (MPPMCL) made a representation dated 14.2.2014 to the Commission regarding Regulation 7 of the Deviation Settlement Mechanism Regulations, particularly pertaining to the limits on deviation volume and the consequences of crossing the limits MPPMCL also filed a Writ Petition No. 3125 of 2014 in the Hon'ble High Court of Madhya Pradesh, Jabalpur on 18.2.2014 challenging Regulation 7 of the Deviation Settlement Mechanism. Hon'ble High Court in its order dated 21.2.2014 issued the notice to the Commission and directed to decide the representation of the petitioner. 1.1 Abstract from discussions in WRPC meetings.

Minutes of meeting of 27th TCC/WRPC held on 21st & 22nd November 2014 at Bhopal The DSM violates basic principle of one penalty for single violation. If an entity under draws at frequency 50.10 Hz and above, it do not get a single paisa for the entire under drawl energy, however a penalty of Rs 1.78/kwh is levied on the entire volume. The Hon’ble Commission may be requested to address this issue to avoid multiple penalties for single deviation.

Constituents were of the view that the charges (capping & additional charges) have been substantially increased which is resulting in heavy penalization to DISCOMS. CE (SLDC) MP


Page 3

stated that the amount of capping and additional charges has increased many folds, since the inception of DSM as compared to the capping and additional charges in the UI regime. Other major concern raised by the beneficiaries was the limit of volume set to +/- 150 MW or 12% whichever is less, irrespective of the utility size. Beneficiaries were of view that the limit of volume should be w.r.t. the % of schedule and not in MW terms. A volume limit of 10-12% of schedule would be a fair limit. There are also penalties even if the state is helping the power system by under drawing at low frequencies.

Chairman WRPC suggested that since all the constituents have more or less same grievances on the issue. 150 MW is too small a deviation and keeping it at 12% or 150 MW or higher (instead of lower) does not appear to have a major negative impact on the grid. He suggested that if other constituents are interested and having grievances they may like to consider joining the petition.

Minutes of 28th meeting of WRPC held on 4.03.2015 at Udaipur MD, MSETCL suggested that a group comprising of representatives from all states be formed and study the problems faced during DSM and suggest the solutions in the next WRPC meeting. If there are difficulties experienced in DSM during operation for many states, then as a region it is necessary to represent the case and also point out acceptable solutions.

TCC recommended the same. It was decided that the Scope of the Group would be to study the operational challenges mentioned above and other related issues if any, which are commonly affecting the states in WR and suggest acceptable solutions and put up to the next WRPC meeting so that the matter may be put up to the Commission as a Region, if required. 1.2 Petition filed by Tripura State Electricity Corporation before CERC Hon'ble CERC heard the petitioner petition filed by Tripura State Electricity Corporation Limited (TSECL) also heard from MPPMCL on identical grievances on implementation of DSM. Hon. CERC had issued an order dated 20.02.2015 on petition filed by TSECL and issued order giving relief to small states, however had not passed any relief to the grievances put forth by MPPMCL. From the order issued by Hon’ble CERC, it is clear that no relief extended to big constituents. The relevant abstract of the order is as under.

“Provided further that when the schedule is less than or equal to 400 MW, the additional charges for deviation shall be based on percentage of deviation worked out with reference to schedule of 400 MW”


Page 4

Form the order it is clear that relaxation on cap volume for large states is not considered by Hon’ble CERC. Hence, issue of difficulties in effective implementation of DSM regulation is still remains unaddressed.


Page 5

2.0 Formation of Committee MD, MSETCL during 28th WRPC meeting, pointed the bigger states like Maharashtra, Madhya Pradesh, Gujarat etc. face a lot of practical difficulties in restricting the deviations within limit of +/- 150 MW under DSM. However the representations with the Hon’ble CERC have been on individual basis (as only MP has approached the Commission). If there are difficulties experienced in DSM during operation for many states, then as a region it is necessary to represent the case and also point out acceptable solutions. He pointed out the following difficulties faced by Maharashtra in DSM:

1. Maharashtra system is having Maximum demand 20000 MW is met by around 14000 MW State generation and Central sector share of 6000 MW.

2. The deviation limit at the periphery as specified in the DSM regulation is 12% of share or +/-150 MW whichever is very meager as compared to the volume of power handled by state network.

3. For the larger states like Maharashtra, Gujrat, Madhya Pradesh, to maintain the deviation of +/-150 MW over a time block of 15 min. is practically difficult as demand is distributed in large geographical area. Also, unforeseen climatic factors and renewable generation in the state are affecting the demand pattern. All available resources are rescheduled continuously to remain in band.

4. Impact of Renewable Energy: The renewable energy particularly wind faces lot of uncertainties. The quantum of wind has gone up in Maharashtra. These variations are far above 150 MW limits prescribed. The RRF mechanism is suspended. In these conditions, the State is unnecessarily burdened with DSM penalties. There is a need for a group to be formed to discuss and suggest solutions.

5. Failure of Communication links: In January 2015, there were instances when the major communication links failed. Under these conditions, the State was asked to back down generation. With frequency being low, the DSM penalties were very high, as it turned out from the energy meter readings that the State was not actually under drawing as seen from the SCADA in absence of links, but was overdrawing. There should be provisions in the DSM to mitigate penalties in such cases where state is asked by WRLDC to back down and links are not fully present.

6. Need for Redundancy in links: There is a need to increase the redundancy in communication links in a phased manner so that the above point does not repeat and cause financial implications.

7. Too small margins: Apart from the RRF factor, the margin of 150 MW for states with demand like 20,000 MW in Maharashtra case, and central shares around 5000-5500 MW is too small to curtail the deviations and seriously requires to be enhanced.

8. Infirm power: New generating units injecting infirm during testing, commissioning and during trial run also cause deviations as this power is not scheduled.

MD, MSETCL suggested that a group comprising of representatives from all states be formed and study the problems faced during DSM and suggest the solutions in the next WRPC meeting. If there are difficulties experienced in DSM during operation for many states, then as a region it is necessary to represent the case and also point out acceptable solutions. TCC recommended the suggestion by Maharashtra and it was decided that the group of the Western Region constituents would study the operational challenges mentioned above and other related issues if any, which are commonly affecting the states in Western Region and to suggest acceptable solutions and put up to the next WRPC meeting so that the matter may be put up to the Commission as a Region, if required. WRPC agreed to the recommendation of TCC as above. During WRPC meeting, it was decided that the group shall comprise of following representation:

` 1) All Chief Engineers of State LDCs 2) Representative from NTPC 3) Officer of the rank of Chief Engineer, from DISCOMs / Holding company if required 4) Any other member as required during discussions

The Chief Engineer, MSLDC shall be convener of committee and outcome of the discussions and deliberations shall be reported during next WRPC meeting. Accordingly, the Chief Engineer, MSLDC called representation from all constituents and a meeting of the group members was held on 22/04/2015 at MSLDC Kalwa. Based on the deliberations, suggestions and submission from members received during this meeting, this report is being submitted.

3.0 Committee proceedings Maharashtra has taken up the issue of DSM limit in various WRPC OCCM and WRPC meetings. The views of all WR constituents are similar and there is unanimous opinion to enhance the limit of +/- 150 MW on state deviation. It is also worthwhile to mention that system operator is continuously engaged in maintaining state drawl schedule and issuing re-dispatch instructions to all intra-state generators and revisions of ISGS schedules. The fact that system operator is continuously engaged in maintaining state drawl schedule leads to divert attention from prime duty of system operator from maintain loading parameters in intra-state network for assuring grid security and integral operation of network. The discipline of maintaining state drawl as per schedule cannot be ignored; however, the grid operations are commercially driven. This result in deterioration of thermal generating units due to ever changing dispatch schedule for pick up and back down instructions frequently. The system operator takes various actions to maintain load generation balance of control area to maintain state deviation within limit. Various corrective measures adopted during under drawl / over drawl are as under.

Under Drawl condition 1. Withdrawal of load shedding, if already in force including supply to Agriculture

Consumers. 2. Reduction of intra-state hydro generation to minimum level. 3. Operation of pumped hydro generating units in pumping mode. 4. Downward revision of inter-state ISGS schedule by as per combined merit order

stack with intra-state generating units. 5. Backing down of intra-state generating units as per combined merit order stack

to their technical minimum. 6. Reserve shut down of ISGS & InSGS units observing the trend of demand pattern. 7. Even if the under drawl is not under control and RE injection is on higher side,

then curtailment of RE injection.

It is observed that even after taking all above steps there are difficulties faced by system operator to control under drawl especially during demand crash scenario.

Over Drawl condition

1 Upward revision of ISGS generating units as per combined merit order stack with intra-state generating units.

2 Pickup of all intra-state thermal generating units to their maximum declared capacity and revision schedules to that effect.

3 Increase intra-state hydro generation as per requirement. Hydro generation is picked up to maximum level during persistent over drawl condition.


Page 8

4 Utilization pumped storage units in generation mode. 5 Implementation of planed load shedding all over the state as per protocol

approved by SERC. 6 Instruction to carry out emergency load shedding by opening of 33/22/11 KV

feeders as per protocol which is already in place and well circulated at sub stations in the field.

Even if over drawl is not under control by taking above measures then there are identified 132 / 220 KV radial feeders which are opened on instruction of system operator. From all above measures system operator continuously takes efforts to maintain state drawl within limit of +/-150 MW. The demand variation in peak & off peak, in different seasons is of the order of 6000-8000 MW which is almost 30-40% of peak demand in case of Maharashtra. It is worthwhile to mention here that Maharashtra is having variable hydro generating capacity about 2500 MW which includes Koyna, TPC Hydro and Ghatghar pump storage. Despite of this variable hydro capacity, sometimes it is inadequate to exercise precise control on state drawl. It is easy to appreciate that the constituents who do not have adequate controllable hydro at their disposal faces more difficulties in regulating their deviations. Maharashtra has carried out extensive analysis of deviations during the period 01st April, 2014 to 31st March, 2015. The data used for analysis is from ABT meter data used for Regional Energy Accounting weekly bills. The data pertaining to schedule & drawl for 35040 time blocks for the period 01st April, 2014 to 31st March, 2015 is analyzed. Following are few highlights of the analysis:

1. Under Drawl below 150 MW is for 60 % of time blocks and 1321 MUs. 2. Under Drawl within the range of 0 to 150 MW is for 6 % of time blocks and 131 MUs. 3. Over Drawl within the range of 0 to 150 MW is for 5 % of time blocks and 106 MUs. 4. Over Drawl within the range of 150 to 200 MW is for 3 % of time blocks and 69 MUs. 5. Over Drawl within the range of 200 to 250 MW is for 3 % of time blocks and 74 MUs. 6. Over Drawl above 250 MW is for 23 % of time blocks and 515 MUs.

As per DSM regulation every constituent has to change sign of drawl after ever 12 time blocks and failure do so, accounts for IEGC violation. The analysis of the data shows that Maharashtra was able to change the sign of drawl after 12 time blocks 1541 times as against 2920 times in one year. This indicates that 53 % times sign change was possible in year 2014-15. Maharashtra also shared commercial impact on state during April 2014 to March 2015 as under:

a. Unscheduled interchange charges of Rs. 122.84Cr. is receivable.


Page 9

b. Amount payable due to cap on UI is Rs. 166.22Cr. c. Additional UI Charges payable as part of penalty is Rs. 101.07 Cr.

It can be seen that UI charges even being receivable as Rs. 122.84 Cr. had end up with Rs. 144.45 Cr. payable. State DISCOMs are facing heavy commercial loss due to capping and additional UI charges which applicable for deviation beyond +/- 150 MW. The failure of the constituent to abide by deviation limits of DSM regulation even after continuous efforts cannot be considered as failure of system operator, but it is has limitations due to ever changing demand pattern and also inadvertent variations of generating units in control area as well as outside control area. The views expressed by Gujrat are on the identical views on following points:

1) Impact of Renewable penetration in grid – Gujrat and Maharashtra are having large quantity of renewable generation installed in state. Maharashtra has renewable installation of the order of 4400 MW with RE injection of the order of 2500 MW in monsoon season. These states are experiencing variation of injection of the order of 1000 to 1500 MW. System operator is totally constrained due to MUST RUN status of renewable and control of over drawl / under drawl within 150 MW limit is actually next to impossible in such operating scenario.

2) Merchant capacity private players play significant role in drawl schedule of the state, many times drawl schedule changes even by 500 MW in consecutive time blocks.

3) More than 200 Open Access users & quantum of transaction is more than 800 MW,

their change in injection / drawl schedule directly affect the state drawl schedule at inter-state boundary.

4) New generators having capacity more than 250 MW are being added to the system

and their infirm generation impacts of state drawl as these generators are not scheduled before COD.

5) The generating units of the capacity 500 / 660 / 800 MW are operating in the state

and tripping such generating unit has direct impact on the drawl of the state. The views expressed by Madhya Pradesh are as below:

1) Tripping of State generator selling power through collective transactions, no revision

is envisaged for collective transaction. Hence, tripping leads state under violation of


Page 10

DSM. Therefore, in such a case, no penalty to be imposed on State for violation of conditions under DSM.

2) As per IEGC clause No. 6.5.19, in case of tripping of the State generator selling power through inter-state bilateral, only one revision is allowed. Original schedule would be made effective from the estimated time (as declared by the generator) of the restoration of the unit. In case, generator doesn’t come on bar as per scheduled time then it leads State under violation of DSM. Generator to be allowed for more than one revision for such a case.

3) At present, RRF mechanism is only limited to scheduling and forecasting of RE

generators. Commercial mechanism outline in RRF mechanism is suspended till further order. In absence of commercial settlement, it has lost its sanctity. New proposed CERC framework for scheduling forecasting and imbalance handling for RE generators to be made effective as early as possible.

4) Accordingly, State should be exempted for violation due to RE variation.

5) At present, grid consists of many 800 MW/660 MW/500 MW capacity generating

units. Tripping of any unit leads immediate violation of DSM. Generator tripping is inevitable. Hence, for such a force major reason there should not be any penalty on state for DSM violation.

For the States having higher demand the DSM limits +/- 150 becomes merely below 1%. No tools are available in INDIA having forecasting error within 1%. Hence, there should be reasonable deviation band to cover forecasting errors.

CERC order No. L-7/139(159)/2008 dated 22.04.2013 in the matter of approval of amendments to the detailed procedure for relieving congestion in real time operation, Annexure-1 (Detailed procedure for relieving congestion in real time operation) clause No. 3.11.1 is reproduced as under. 3.11.1. Two percent (2%) of the total anticipated peak demand met in MW of the control

area/group of control area/region (to account for forecasting uncertainties) Above clause clearly indicates/accepts the forecasting uncertainty as 2% and this level error in forecasting can be achieved only proper forecasting tool with sufficient historical demand data, meteorological parameters and sufficiently accurate weather forecast is available as input data to the forecasting tool. Presently, no state is equipped with such sophisticated forecasting tool. Hence, apparently considering the State Peak demand of big states of the order of 14000 to 20000 MW, forecasting error is much higher that DSM limit of +/-150 MW.


Page 11

The deviation limit specified under DSM mechanism is very low and it almost impracticable to maintain drawl within limit due to dynamics and ever changing demand pattern on demand side. Frequent variation of intra-state resources as detailed above on other side, system operator is facing much difficulties in maintaining state deviation within band of +/- 150 MW due to inherent system dynamics. From all above facts/submission by all western region constituents it is crystal clear that the deviation limit prescribed by DSM regulation is not practically achievable. Also, the question remains that why this fact was not brought out in early stages of DSM implementation. The reason behind that all constituents had already submitted their comments/suggestions in response to the concept paper published by CERC, however cognizance of the same had not been taken at the time of issue of DSM regulation. This is to mention here that Statement of Reasons (SoR) was not published at the time of notification of regulation. Further, all constituents have honored this regulation and put maximum and sincere efforts to abide by the provisions of the regulation. However, it is the fact that even after taking sincere efforts it not possible to abide by deviation limits. The issues faced by constituents were discussed at regional forum and finally arrived at the conclusion that issue needs to be referred jointly to Hon’ble CERC. Other related issue of monitoring of Drawl of constituents by RLDC. RLDC monitors drawl of all constituents against their respective schedules and issue notices on the basis of drawl figure available on RLDC - SCADA system. Actual drawl of constituents is arithmetic summation SCADA data of different drawl points. Computation of actual drawl is summation of more than 60 to 70 nos. of instantaneous MW values from various locations. This data comprises of data from ISGS - RTUs and also from data from STU RTUs. Most of the time correct data of all interface points are not available and many values are non-current / invalid due to various reasons including communication failure. System operation is carried out on SCADA data and billing is carried out on the basis of ABT meter data. It is observation of all constituents that drawl data do not match with each other and there is wide variation in these data sets. The SCADA error is mis-leading to system operator for taking decisions on control action in maintaining deviation within limit of 150 MW and resulting in wastage of resources followed by huge financial impact in actual billing being post facto activity based on meter data.


Page 12

In the order, in petition filed with CERC by Tripura in case No. RP/06/2014 clause no 18(n) it is mentioned that “As per SCADA data MP had to receive about `9.00 Crore but as per actual UI accounts, MP was payable by 5.31 Crore” All constituents are facing problem of monitoring actual drawl data computed on the basis SCADA inputs from all interface points. RLDCs are in process for acquisition of ABT meter data from all inter-state/ inter-region interface points under Automatic Meter Reading (AMR) scheme. ABT meters are compatible for transmission of instantaneous MW data at fixed interval. Acquisition of instantaneous MW data from interface meters and computing drawl of constituents will give correct drawl figures in addition to SCADA data. This data also can be made available to constituents for reference.


Page 13

Proposal for consideration After detail deliberations and from the submission of all Western Region constituents, the committee proposes DSM limits as below: Part A : Proposed Deviation Limits

1. Schedule below 400 MW : 48 MW. ( Already approved by Hon’ble CERC) 2. Schedule between 401 to1250 MW : 12 % or 150 MW whichever is lower. 3. Schedule between 1251 to 1500 MW : 150 MW. 4. Schedule above 1501 MW : 10 % or 400 MW whichever is lower. 5. 20 % penal charges for deviation between 401 to 500 MW 6. 40 % penal charges for deviation between 501 to 600 MW 7. 100 % penal charges for deviation above 600 MW. 8. Under drawl cap for under drawl exceeding 400 MW 9. Penal charges for under drawl above frequency 50.10 Hz for under drawl exceeding 400

MW. 10. The provision of change in drawl sign in 12 time blocks may be continued.

Part B : Data acquisition from interface ABT meters. Respective RLDCs may please be directed to acquire instantaneous MW data from interface ABT meters and computed drawl data of respective constituent on the basis of this data and shall be made available in real time. Way forward In compliance to the directives issued during 28th WRPC meeting, this report is being submitted to WRPC. WRPC may like to discuss and consider to share this report to all constituents / DISCOMs. All DISCOMs shall file a joint petition to Hon’ble CERC and SLDCs shall extend all possible help to DISCOMs. This report shall also be shared with other states in country and similar action is envisaged from other states in country.
