ITEM NO 2 : SYSTEM STRENGTHENING

2.1Conversion of fixed Reactor to switchable Reactor;

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

2.2 Extension on 220 kV Network at GIS Navi Mumbai station

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 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.

MSETCL and PGCIL may update the status.

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


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 and also 400/220 kV is not operating since the last one year.

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.

MSETCL May update the status.

2.4 Readiness of Kudus sub-station :


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 be kept ready the 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).

MSETCL May update the status.

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:

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 and 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 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 mechansism of

how it could be shared may be also brought 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.

NCA may update the status & Committee may discuss the same.

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/WRPC members may like to discuss.

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

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.

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

A) Revision of DSM Accounts and payment of interest thereof : 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 written 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 furnishedby WRLDC by Friday & WRPC based on this data has to issue the DSMA/c on Tuesday. Suspension of A/cs as suggested means delayedissuance of the A/cs as per regulations. Further the pool member wouldsuffer in case of errors in a/cs which are beyond their control.

Followings are recommended;1) If the a/c is revised within the due date of the original a/c due toerrors beyond the control of pool members, the amount payable by poolmembers shall be as per the revised a/c and the due date shall be as perthe revised a/c.2) If the a/c is revised after the due date of the original a/c due toerrors beyond the control of pool members, a mechanism should beformulated such that the interest be receivable by the pool members who


have paid excess amounts as per the original a/c than the amountspayable by such pool members as per the revised a/c.

TCC/WRPC may discuss and guide in this matter.

B) STOA revisions : 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.


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

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. WRPC agreed in principle and

suggested discussion in technical committee meeting to 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. Matter was again 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.

PGCIL may give the brief details on above & WRPC/TCC may discuss thesame.

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.

PGCIL, Alstom and Members agreed the same.

TCC/WRPC members may like to note.

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.



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 of

WRPC in the 28th WRPC meeting. PGCIL representative informed that they

have worked out the hardware and associated requirement and confirmed that

original configuration is adequate to the meet the above data flow.

Requirement of enhanced capacity in view of above has been worked out by

PGCIL which will be implemented in the 2nd phase.


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.


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 for

dedicated man power of 2-3 persons in each control centres to be provided

respective utility (SLDC/RLDC/….).

TCC/WRPC members may like to discuss and approve.

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.

TCC/WRPC members may like to discuss and approve.

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 was received at all

envisaged generating stations i.e. KSK, JPL, JPL Extension, NSPCL, BALCO, KWPCL and

DB Power.

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 envisagedfor HVDC Thalcher-Kolar SPS might have acted correctly. However during theoccurrence generators at Meenakshi(150MW), SDS TPS (800MW), RaichurTPS(210MW) and Ramagundam-Bhadrawati Pole 1 was out of service. This led toincrease in loading on Raichur-Sholapur lines, but the load shedding in SR was notadequate (due to combined effects of HVDC Thalchar-Kolar tripping and Generationtrippings in SR). Further it is suspected that SPS settings as per NLDC letter dated07.07.2014 is not revised at Raichur end(i.e. blocking of tripping for O/L when bothckts are in service). This led to tripping of the lines from Raichur end. . Committeerequested WRLDC to take up the matter with NLDC / SRLDC / ERLDC. Further, theloads to be shed identified for Thalchar-Kolar SPS & Raichur-Sholapur SPS shouldbe independent of each other.


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 PCM felt that angular difference estimated/assessed during the synchronizationby WRLDC may not be around 115 degrees, since synchronization at such anangular difference would have resulted power flows of the magnitude of phase tophase faults. However there was some problem during synchronization whichneeds to be brought out by studying the incidence in great depth by central agencylike NLDC/CEA.

Subsequently considering the seriousness of the above events, WRPC vide letterdated 17.06.2015 took up the issue with CEA. NLDC have published a report on theabove events and a copy is available at WRPC web-site..

TCC/WRPC members may like to discuss/note.

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.


12.2: Review of SPS for CGPL Mundra:

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

Based on the studies carried out by WRLDC in consultation with SLDC GETCO, CGPL and

WRPC the

Revised SPS agreed is as follows;

Sl. No. SPS triggering condition Actions required Comments

CGPL vide letter dated 18.05.2015 have intimated that the above logics have beenimplemented at CGPL Mundra since 08.05.2015.


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.


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.

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)

ITEM NO.21: PERFORMANCE OF WR GRID DURING FEBRUARY 2015 TOJUNE 2015

21.1 SYSTEM PERFORMANCE

Frequency:During months of February 2015, March 2015, April 2015, May 2015 & June

2015 the grid operated in the IEGC frequency range of 49.9 Hz to 50.05 Hz for

60.15 %, 58.47 %, 60.20%, 64.74 % and 65.01 % of time respectively. The

frequencies below 49.9 Hz were from 12.30 % to 17.77 % of time during

February 2015 to June 2015. In higher frequency regime, system frequency

remained above 50.05 Hz from 19.44 % to 27.55 % of time during February

2015 to June 2015. The monthly average frequency was 50.00 Hz in February

2015 , 49.98 Hz in March 2015, 49.99 Hz in April 2015, 49.98 Hz in May 2015

& 50.00 Hz in June 2015.

The detail of frequency profile for the months of during February 2015 to June

2015 is placed at Annexure-21.1(a).

Demand :

The maximum unrestricted demand of Western Region was in the range of

42600 MW to 43580 MW(Ex Bus) in during February 2015 to June 2015. The

region faced capacity shortage in the range of 200 MW to 725 MW (peak

deficit of 0.50 to 2.00 %) respectively during these months. The details of

unrestricted peak demand, demand met and energy requirement and

availability are as furnished at Annexure-21.1 (b).

21.2 Voltage Profile

Overall voltage profile had been satisfactory during the period under review.

However, instances of high voltages beyond the IEGC specified operating

range were observed at some of the EHV sub-stations in the region. Higher

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

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

Page 2 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.

Page 3 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.
