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
locations :

During 28th WRPC/TCC, it was recommended to convert the above fixed line
reactors as switchable reactors without any system study.
PGCIL may update the status.
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.
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad4
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.
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad5
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.
During 28th WRPC/TCC meeting, Member Secretary WRPC 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 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.
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad6
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 :
During 28th WRPC/TCC meeting, Member Secretary WRPC 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 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
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad7
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:

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

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..
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad9
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.
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad10
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
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad11
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
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad12
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.
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad13
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/WRPC members may like to discuss.

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
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad17
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
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad18
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
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad19
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/WRPC members may like to discuss.
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
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad20
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
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad21
requested to complete Alstom SCADA commissioning and testing by

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,

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/WRPC members may like to discuss.
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad22
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.
TCC/WRPC members may like to note.
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
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad23
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/WRPC members may like to note.
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
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad24
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
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad25
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.
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad26
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..

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
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad27
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.
TCC/WRPC members may like to note.
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;

TCC/WRPC members may like to note.
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
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad29
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
Agenda notes of 29th meeting of WRPC to be held on 24.07.2015 at Aurangabad30
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.

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

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

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)

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.
