4. NATIONAL POWER COMMITTEE (NPC)/IMPLEMENTATION OF ENQUIRY
COMMITTEE RECOMMENDATIONS
4.1 In the 22nd
Meeting of SRPC, it had been agreed that the concerns regarding
‘considered concurrence’ and other modalities would be taken up with NPC. The
Membership of PGCIL and NTPC to the NPC forum would also be recommended.
4.2 Accordingly, Chairperson SRPC vide letter dated 31st
May 2013 (Annexure-IV) had
taken up these issues with Chairperson, CEA.
4.3 The Second Meeting of NPC was conducted on 16th

The Summary Record of Discussions of the Second NPC Meeting is enclosed as
Annexure-V. On the matter of ‘Methodology to bring agenda item in NPC by
RPCs – providing adequate time to RPCs’, the following had been decided:
Upon deliberations, it was decided that the agenda items from members
of RPCs for the NPC Meeting would be routed through their respective
Member Secretary after discussions at RPC level. It was also decided that
if some Members feel the necessity for discussing certain issues with their
constituents before giving their opinion thereon, they may seek the option
of getting it discussed at their respective RPC and revert back to NPC to
enable NPC take a final decision on the agenda item at its next Meeting.
4.4 Further, the following had been decided with regard to ‘Inclusion of NTPC & PGCIL
in the NPC Forum’:
Taking into consideration the opinion of the members, Chairperson, NPC &
CEA decided that the present arrangement of inviting CPSUs as special
invitees to NPC meetings, whenever considered necessary, would be
continued. However, he opined that NLDC could be included as a member
in NPC. He advised the RPCs to consult their constituents in the matter and
communicate their opinion at the next meeting.
4.5 The issues deliberated in the Second NPC Meeting were also discussed in the
Special Meeting of TCC held on 21st
August 2013. Chairperson, SRPC & CMD
APTRANSCO vide letter dated 22nd

Meeting may please be arranged.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 6
4.6 In the Meeting, MS I/c, SRPC informed that TCC had recommended for SRPC
consideration, inclusion of NLDC as well as CTU as Members to the NPC. It had
also been agreed that Agenda Items for the NPC Meetings, if any, would be
routed through Member Secretary, SRPC.
4.7 Chairperson, SRPC & CMD, APTRANSCO suggested that the Recommendation of
TCC could be agreed to.
4.8 The Committee approved the Recommendation of TCC in this regard. It was also
decided that Chairperson, SRPC would take up with Chairperson, CEA
recommending inclusion of NLDC and CTU to the NPC forum.
4.9 Implementation of measures to prevent Grid Disturbance
(A) Third party Protection Audit:
(a) In the Second Meeting of NPC, the following had been deliberated:
� CEA would be seeking supplementary information from the
States shortly on the DPRs submitted by them to bring some
uniformity therein.
� It had been agreed that the DPRs received from the States
would be treated as approved by their respective
managements.
� As per the consolidated DPR submitted to MoP funding from
PSDF had been proposed as 20% keeping in view the amount
parked in PSDF. This could vary depending upon the amount
approved by MoP/PSDF Management Committee. CERC
Regulations on PSDF were also in the process of review.
� It had been decided that the States would immediately take up
renovation and up gradation of protection system including
switchgears at their substations as mentioned in their
respective DPRs without waiting for the funds from the Centre.
As the funds become available from PSDF, the same would be
distributed to the States as per the guidelines /regulations in
force.
(b) In the Special Meeting of TCC held on 21st
August 2013, it had been
felt that the 20% funding proposed from the PSDF was inadequate.
States had also brought to attention the acute resource crunch being
faced by them. It was also stated that amounts required for
renovation and up gradation works had not been factored in the ARR
projections furnished to the respective SERCs. Utilities had therefore
requested that the 20% funding proposed be kindly reviewed by CEA
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 7
and the same be modified to 100% funding. This would ensure
completion of the scheme and also ensure grid security in the shortest
possible time.
(c) SRPC Secretariat & SRLDC had stated that renovation and up gradation
works were needed to be taken up immediately without linking the
same to any funding etc, since they were required functionally.
(d) TANTRANSCO vide letter dated 22nd
June 2013 (Annexure-VII) had
stated that necessary administrative approval for procurement and
other related activities could be obtained only upon a decision
towards funding assistance from PSDF. The matter was accordingly
brought to the kind attention of Member Secretary, NPC vide SRPC
letter dated 26th
June 2013. Chairperson, SRPC & CMD APTRANSCO
vide letter dated 23rd
August 2013 (Annexure-VIII) addressed to
Chairperson, CEA had informed that it had been felt that the 20%
funding proposed from PSDF was grossly inadequate in view of the
acute resource crunch being faced by the states. Hence, it had been
requested that 20% funding proposed, be reviewed by CEA and the
same modified to 100% funding as a special case.
(e) In the Meeting, MS I/c, SRPC informed that TCC had recommended the
following:
� Utilities would carry out implementation of the
Recommendations relating to Third Party Protection Audit
as per prioritization in a phased manner. The Schedule of
activities would be furnished within one month and would
be discussed in the Protection Sub Committee Meeting.
� Issue regarding 100% funding though PSDF would be taken
up with MoP, Government of India.
� Utilities would commence works identified in the above
schedule without waiting for funding.
(f) Chairperson, SRPC & CMD, APTRANSCO said that grid security was of
utmost importance. Hence, the best option would be to go ahead
with implementation of the scheme in a phased manner from own
funds. Concurrently, funding from PSDF could also be sought for the
works executed as well as for the balance works.
(g) MD, APGENCO pointed out that the DPR for each utility was around
`100 Crores or more while for the entire SR, it could be more than
`600 Crores. He therefore said that “in principle” agreement from
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 8
Govt. of India for funding was essential in view of the high level of
investments involved.
(h) Chairperson, SRPC & CMD, APTRANSCO opined that even though the
investments were high, the works were needed to be carried out in
the interest of grid security. Linking commencement of works with
PSDF funding may be a risky decision. Hence, utilities could
commence works in critical areas in a phased manner based on the
resources available with them.
(i) Chairman, TANTRANSCO informed that TN had taken up with MoP
for release of PSDF funds for protection up-gradation by the utilities.
He pointed out that PSDF was governed by a set of Regulations and
was managed by CERC. He therefore suggested that Chairperson,
SRPC could take up with Secretary MoP and also with Chairperson,
CERC regarding funding from the PSDF. Issues such as fund
management, fund disbursement, retroactive financing etc were
also needed to be addressed. He expressed concern on the
unutilized amounts lying in the PSDF for a considerable period. He
also endorsed the views of Chairperson, SRPC that implementation
could commence in a phased manner from own funds of the
utilities. In the meanwhile, MoP could be urged for an early decision
regarding support from the PSDF.
(j) Chairperson, SRPC & CMD, APTRANSCO suggested that
disbursement of funds from PSDF could be based on some formulae.
States should be given the liberty to utilize the funds not only for
protection related works but also for works related to modernization
etc. as per their priority.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 9
(k) After deliberations, it was agreed that Chairperson, SRPC would
address a letter to Secretary (Power), MoP requesting support from
PSDF for protection up gradation works planned by the Utilities with
provision for retroactive funding. It was also felt that a mechanism
should be in place for disbursement based on the hierarchy of needs
and prioritization. Utilities would carry out implementation of
Recommendations relating to Third Party Protection Audit as per
prioritization in a phased manner. The Schedule of activities would
be furnished within one month and would be discussed in the
Meeting of Protection Sub Committee.
(B) Reactive Power Planning
� In the Second Meeting of NPC, it had been decided that all States
would carry out reactive power planning not only at transmission
level but also at distribution level and prepare schemes to maintain
voltage profile as per relevant Regulations/Standards. The schemes
would be forwarded by the States to the Power System Wing of CEA
under intimation to the NPC Secretariat at the earliest. Further,
execution of the approved schemes would be taken up by the States
without waiting for funds from PSDF.
� In the Special Meeting of TCC held on 21st
August 2013, the
Constituents had stated that they would rework the scheme
including distribution level and would apprise their management in
this regard. They had expressed that full funding be made through
the PSDF. SRLDC & SRPC Secretariat had stated that the scheme
should be taken up without linking it to any funding etc.
� In the Meeting, MS I/c, SRPC informed that in the TCC Meeting,
Utilities had agreed to furnish the schemes relating to Reactive
Power Planning, including at distribution level within one month.
The time schedules for implementation would also be indicated.
Utilities had also requested for funding from PSDF.
� Chairperson, SRPC & CMD, APTRANSCO said that utilities needed to
commence works which were critical from the technical point of
view. These too should be taken up without any linking to the aspect
of funding from PSDF.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 10
� Director (Tr.), KPTCL stated that reactive compensation at
distribution level was also critical. He added that Karnataka had
carried out studies and identified locations for capacitors addition at
11 kV & 66 kV levels. In addition, reactor requirement at 400 kV level
had also been identified.
� MD, KPTCL endorsed the views of Chairperson, SRPC and said that
the work could be commenced by utilities from their own funds.
However, he added that track of the works being carried by the
utilities needed to be kept, which would be helpful in event of
retroactive funding.
� Chairman, TANTRANSCO stated that based on system requirements,
capacitor addition were already being carried out by the utilities and
this was an ongoing process. Certain schemes like APFC were also
being financed through RAPRDP etc and hence he opined that this
need not be linked with funding from PSDF. Presently, funding from
PSDF could be limited to Protection Up gradation works. Utilities
could carry out reactive compensation works and the progress of
these schemes could be monitored in the technical meetings in
SRPC. All schemes could not be proposed for funding from PSDF,
since it would lead to lesser funding for Protection Up gradation.
� Chairperson, SRPC opined that part of PSDF funds could be tied with
identified schemes while other untied funds could be utilized by the
utility as per its requirement.
� After deliberations, it was agreed that Utilities would furnish the
schemes relating to Reactive Power Planning including at
distribution level within one month indicating also the time
schedules for implementation. Progress of these schemes would be
monitored in the SRPC forum. Request for funding through PSDF
could be sought at a later date.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 11
(C) Ensuring proper functioning of UFRs and df/dt relays
� In the Second Meeting of NPC, it had been decided that all SLDCs
and RLDCs would upload the details of feeders to be tripped through
the UFRs and the expected load relief at different frequency levels in
their respective States/Regions on operations of UFRs. It had been
also decided that RPCs would send inspection report of healthiness
of UFR and df/dt regularly on a quarterly basis to the NPC
Secretariat.
� In the Special Meeting of TCC held on 21st
August 2013, KSEB had
informed that the scheme had been extended to 11 kV feeders also.
TANTRANSCO had informed that additional UFRs were being
procured/shifted to implement the additional quantum of 400-550
MW relief under UFR.
� SRPC Secretariat had carried out UFR & df/dt relay inspection in a
few substations in Andhra Pradesh, Karnataka & Kerala. Rectification
report for compliance had been furnished to the utilities.
� SRLDC had reported the matter regarding AUFR and df/dt protection
scheme performance as per clause 1.5 of IEGC, 2010. As per the
monitored values by SRLDC, the expected quantum in many critical
instances was far below the expected quantum. The AUFR and df/dt
protection scheme performance in the region needed improvement.
� In the Meeting, MS I/c informed that in the TCC Meeting the
following had been noted:
� Utilities had agreed to ensure desired relief through
identification of additional feeders and if required, feeders
would be added at lower voltage level (distribution level).
States would come up with an action plan in this regard.
� Detailed analysis would be carried out in the OCC
Meetings to identify areas requiring critical improvement.
� ED, SRLDC raising concern said that only about 40-50 % relief of the
desired relief was visible in the SCADA. During UFR operation, about
20 to 30% only of the desired relief was being realized. He informed
that detailed analysis was already being carried out. A Report was
being communicated to the states/SRPC secretariat once in every 10
days. He requested utilities to provide relays at lower voltage levels
also ensuring that the desired quantum of relief is thus achieved.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 12
� After deliberations, it was agreed that detailed analysis would be
carried out in the OCC Meetings to identify critical improvement
areas. Utilities agreed to ensure desired relief through identification
of additional feeders. In case required, feeders would also be added
at lower voltage levels (distribution level). States after internal
analysis would come up with an action plan in this regard.
(D) Islanding schemes
� In the Second Meeting of NPC, CEA had requested all RPCs to submit
the details of progress of preparation/approval/execution of
islanding schemes to NPC Secretariat regularly on fortnightly basis.
� In the Special Meeting of TCC held on 21st
August 2013, it had been
noted that modified S1-S2 islanding scheme would be completed by
August 2013. Other islanding schemes would be completed by
October 2013. In the Protection Sub Committee Meeting held on

� In the Meeting, MS I/c informed that in the TCC Meeting the following
had been noted:
� PGCIL had informed that they had analysed the Zone-3
settings on all India basis keeping in view settings being
adopted by different utilities, issues relating to different
manufacturers etc. They had certain observations with
regard to some of the settings adopted in SR.
� TCC had suggested that PGCIL may furnish these
observations to SRPC Secretariat for circulation. It was also
agreed that the issue would be deliberated in the
forthcoming Meeting of Protection Sub-Committee
scheduled to be held on 21st

4.12 Ring Fencing of Load Despatch Centers (LDCs)
4.12.1 In the Special Meeting of TCC held on 24th
June 2013, the following had been
noted:
� APTRANSCO had informed that interactions were underway and the
State Government had to take a view in this regard. Presently
separate SLDC accounting was being carried out.
� KPTCL had informed that the issues were under discussions at
Government level. Separate SLDC accounting was being carried out
in Karnataka also.
� KSEB had informed that the issue of asset transfer etc. was under
discussion. It could take around three months’ time for finalization
of this issue. Subsequently, the issue regarding Ring Fencing would
be taken up.
� TANTRANSCO had informed that separate ARR for SLDC had already
been put up to TNERC.
� Puducherry had informed that the Reform Steering Committee had
identified a Nodal Officer in January 13. The Report of the Nodal
Officer was awaited.
4.12.2 In the Second Meeting of NPC, it had been decided that inputs with regard to
status of implementation of Pradhan Committee Recommendations on Ring
fencing of SLDCs would be collected by RPCs from the States and forwarded to
NPC Secretariat every month.
4.12.3 In the Special Meeting of TCC held on 21st
August 2013, the following had been
noted:
� APTRANSCO had informed that SLDC accounts were different from
APTRANSCO accounts and separate Tariff had been issued by APERC.
State Government had to take any decision in this regard.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 15
� KPTCL had informed that since last four years, SLDC accounts were
being maintained separately and paid by the DISCOMs. This was a
policy matter and decision to be taken by Government.
� Ring fencing had to be adopted in totality so as to achieve desired
autonomy.
4.12.4 In the Meeting, MS I/c, SRPC informed that the following had been noted in
the TCC meeting:
� Utilities had been requested to furnish monthly status reports to
SRPC Secretariat.
� Utilities had observed that Ring fencing was a Policy matter of the
Government.
� ED, SRLDC had expressed concern over the low number of
nominations by SLDCs to the System Operators Training Programme
in PSTI. He had requested for increased number of nominations to
such Programmes in order to increase the proficiency of System
Operators.
4.12.5 Chairperson, SRPC opined that SLDC could be ring fenced within the
TRANSCO itself. Mere creation of one more Government Company may
not achieve the desired objective of ‘Ring Fencing’. Fixing appropriate
responsibility on the existing company could be the right way forward.
4.12.6 Director (Tr.), KPTCL opined that necessity of one more company may not
be required, since it would entail avoidable additional corporate structure
etc.
4.12.7 ED, SRLDC suggested that in the existing company itself, the revenue
streams could be bifurcated. APTRANSCO & KPTCL informed that this
exercise had already been carried out by them.
4.12.8 Chairman, TANTRANSCO stated that CEA had already been requested to
consider 3 to 5 years’ time period for implementation, this being a major
regulatory issue. TN had also filed a separate petition before TNERC with
regard to ARR for SLDC. Ring fencing in the form of revenue stream, ARR
etc. could be carried out while in parallel Capacity building could also go
on. System Operator Certification could continue under the guidance of

POSOCO. However, some more time was required to make SLDC a
separate Company. CEA and the Government of India could be requested
in this regard.
4.12.9 Chairperson, SRPC & CMD, APTRANSCO said that as suggested, financial
independence within the present framework could be granted while later
a separate company could be contemplated. Capacity building exercise
could also go on.
4.12.10 After deliberations, it was decided that Chairperson SRPC would convey
the views of the forum to CEA/MoP.
4.13 Implementation of CEA Regulations
� In the Second Meeting of NPC, it had been decided that as a first step,
that all power utilities be sensitized on CEA Regulations through
workshops in Regional Fora. After completion of awareness phase, the
violations of CEA Regulations could be discussed and minuted in RPC
Meetings and persistent violations reported to Hon’ble CERC.
� In the Special Meeting of TCC held on 21st
August 2013, it had been
noted that the following Regulations are available on the CEA website:
� CEA (Safety requirements for construction, operation and
maintenance of electrical plants and electric lines)

of Statistics, Returns and Information.
� In the Meeting, MS I/c, SRPC informed that TCC had suggested that
CEA be kindly requested to send its Officers to the RPC forum to help
improve awareness of the Regulations through Workshops, Seminars
etc.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 17
� Chairperson, SRPC & CMD, APTRANSCO opined that increased
awareness could be created in these Workshops, during which the
experts could go into issues threadbare.
4.14 Number of Stages for AUFLS
� In the Second Meeting, NPC had decided to implement AUFLS with
four stages of frequency viz. 49.2, 49.0, 48.8 & 48.6 Hz in all the
Regions. SRPC had been asked to follow the above four stages of
frequency since SR Grid was also going to be synchronized with NEW
Grid soon. Member Secretary, NPC vide letter dated 06th
August 2013
had stated that as per discussions in the second NPC Meeting, the first
two stages of AUFRs i.e. at 49.2 Hz and 49.0 Hz be implemented by
25th
August 2013 by utilizing the existing frequency relays. The other
two stages are to be implemented within three months, as agreed in
the NPC Meeting.
� In the Special Meeting of TCC held on 21st
August 2013, all constituent
States had agreed to implement AUFLS with four stages of frequency
viz. 49.2, 49.0, 48.8 & 48.6 Hz. As a first step towards the same, setting
on feeders of current stage– I & II would be changed to 49.2 Hz and
49.0 Hz within two weeks. The other stages would also be
implemented after procurement of additional relays required, if any,
to adopt four stages of setting.
� In the Meeting, MS I/c, SRPC informed that in the TCC Meeting it had
been noted that all revised four stages of UFR in the Region had been
implemented. However, TANTRANSCO would implement some
balance quantum under fourth stage (48.6 Hz) by end November 2013.
� Chairperson, SRPC & CMD, APTRANSCO enquired whether inspection
of relays was being carried out through third party audit. MS I/c, SRPC
informed that SRPC Secretariat was carrying out inspection of relays
installed at substations on a representative basis. Findings during the
inspection were being communicated to the utilities for needful.
4.15 Methodology for determination of quantum of load for AUFLS in different
Regions
� In the Second Meeting of NPC, it had been agreed that the quantum of
load shedding for NEW grid under AUFLS, as worked out in the agenda
was in order and the same could be communicated by NPC Secretariat
to all the RPCs for implementation. The same methodology could be
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 18
adopted to determine the quantum of load shedding at four stages of
frequency based on the power number for SR grid and communicated
to SRPC for implementation. It had also been agreed that the entire
AUFLS scheme be implemented in a maximum period of three months
by all RPCs.
� Based on the CEA letter dated 6th
August 2013, in the Special Meeting
of TCC held on 21st
August 2013, State-wise Break-up of the UFR
quantum to be provided at each stage had been presented.
5. BRINGING THE DRAWAL OF POWER BY PUDUCHERRY FOR KARAIKAL REGION
UNDER THE REA OF SR
5.1 Puducherry vide letter dated 01st
October 2013 (Annexure-IX) had proposed that
accounting of drawal of power for Karaikal Region be brought under Regional
Energy Accounting of SR.
5.2 In the Meeting, MS I/c, SRPC informed that in the TCC Meeting, Puducherry had
been suggested to put up a detailed proposal in the ensuing meeting of
Commercial Sub-Committee. The outcome would then be placed in the ensuing
TCC/SRPC meetings.
5.3 Chairman, TANTRANSCO stated that Puducherry & Karaikal being enclave
territories in TN, the limited suggestion was that drawal of power by Puducherry
at Karaikal be under Regional Energy Accounting framework and within its
regional entitlement, provided TN transmission network permitted the same.
6. HASSAN – MYSORE 400 KV D/C LINE UNDER SYSTEM STRENGTHENING SCHEME
6.1 In the 22nd
SRPC Meeting, the following had been noted:
� KPTCL had informed that the Tripartite Agreement was ready and the
same would be furnished to Punjab & UPCL within a week’s time.
� APTRANSCO had observed that the issue regarding LTA quantum in
respect of Karnataka needed to be expedited, since it was long
pending.
� SRPC had approved the following course of action suggested by TCC in
this regard :
� MS I/c, SRPC may take up the issue with Punjab for revised
LTA quantum based on 10% capacity of UPCL plant. This
would relieve the IR corridor and have some relief on
transmission charges also.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 19
� Regarding LTA quantum in respect of Karnataka, Member
(PS), CEA be requested to kindly convene a separate
Meeting with the constituents.
6.2 Subsequently, MS I/c, SRPC vide letter dated 20th
May 2013 (Annexure-X) had
taken up the issue with PSPCL. Further, as agreed in the 22nd
SRPC Meeting, SRPC
vide letter dated 20th
May 2013 had kindly requested CEA to convene a Meeting
to discuss and resolve the matter regarding LTOA quantum of Karnataka. Further,
Chairperson, SRPC & CMD APTRANSCO vide letter dated 10th
September 2013
(Annexure-XI) addressed to Chairperson, CEA had also requested that CEA may
convene a Meeting regarding LTA quantum in respect of UPCL plant.
6.3 KPTCL vide letter dated 7th
August 2013 had furnished the revised Tripartite
Transmission Agreement to PSPCL. PSPCL vide letter dated 16.09.2013 (Annexure-
XII) had intimated the receipt of the draft agreement. It was also stated that the
matter be finalized at the earliest so that further action for signing of the TSA
could be taken by PSPCL. UPCL vide letter dated 17th
August 2013 had stated that
the need for UPCL to become a party to the TSA did not arise.
6.4 In the Meeting, MS I/c, SRPC informed that TCC had suggested convening of a
Special Meeting to resolve the issues regarding scheduling of power to Punjab &
also with regard to finalization of the LTA quantum.
6.5 Chairperson, SRPC & CMD, APTRANSCO noted that this issue was a long pending
one and should be resolved without further delay. He suggested that a small
group of senior officials could sit together to analyze the issues in depth for
evolving an amicable solution.
6.6 Director (Tr.), KPTCL suggested that “one to one” Meeting could be held first and
then a Meeting with participation from all could be convened.
6.7 MS I/c, SRPC stated that scheduling of power from UPCL to Punjab needed to
commence. Scheduling of power to Punjab would help reduce the transmission
charges liability of other Constituents to some extent besides freeing the corridor
to the extent of 100 MW.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 20
6.8 Senior Vice President, UPCL informed that there was no issue regarding
scheduling of power to Punjab. He suggested that the issue be deliberated in a
separate meeting with the concerned parties.
6.9 Chairman, TANTRANSCO stated that this issue had to be resolved at the earliest in
common interest. Scheduling of power to Punjab would also facilitate 100 MW
additional corridor to the SR constituents. He suggested SRPC Secretariat may
convene a Meeting at the earliest in this regard.
6.10 After deliberations, it was agreed to convene a Special Meeting to resolve the
issues regarding scheduling of power to Punjab besides finalization of the LTA
quantum.
7. NEW PROJECTS OF NTPC, NLC, NPCIL, JOINT VENTURE & UMPP
7.1 NTPC-Kayamkulam 1950 MW/1050 MW Plant
7.1.1 In the 22nd SRPC Meeting, the following had been noted:
� NTPC had intimated that the Draft PPA had been circulated to all the
States and concurrence/comments were awaited. Discussions with
M/s. GAIL were on regarding pipeline. However, before concluding
the agreement with M/s. GAIL, the PPA with the states needed to be
signed. Chairman, NTPC vide letter dated 10th
May 2013 had also
addressed a letter to the States in this regard. The indicative tariff
mentioned in the letter was around `9.12 per unit, if it was LNG.
However, in case domestic gas was available, the tariff would be
lower.
� KSEB had informed that they would like to avail 500 MW from the
project. The mode of transport of gas from Kochi to Kayamkulam
was to be finalized in consultation with GAIL & other agencies.
Though some discussions had taken place, there were no
conclusions.
� PGCIL had stated that the gestation period of gas plant was less than
24 months while transmission evacuation schemes especially in
Kerala would take much longer time. Hence, LTA quantum needed
to be communicated sufficiently in advance to finalize the
evacuation schemes to match the generation.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 21
� APTRANSCO had stated that NTPC should envisage the project only if
they were sure of gas/RLNG supply in future. Against the anticipated
supply of 80 mmcmd from KGD-6, the supply was Nil. About
`30,000 Crores investment which had been made was not being
utilized. Though MoP had given the go ahead to the Developers, the
actual fuel supply was missing in this case. AP was losing about 70
MU/day of energy because of this shortage. Firming up of fuel
supply for 20-25 years and also the cost needed to be finalized and
confirmed by NTPC to avoid blockage of capacity as had already
occurred in AP. AP was not interested in availing power from this
plant.
� KSEB had informed that Petronet has set up a terminal at Kochi and
was having back to back arrangements for RLNG supply for 25 years.
Underground marine pipeline from Kochi to Kayamkulam (52 kms)
was being studied and could take another one and half years. With
landed fuel cost at around 16 dollars and 2 dollars cost estimated
towards pipeline, the tariff worked out to `9.16/unit. The gas supply
agreement as well as transport agreement were ready to be signed,
provided the PPAs were in place. KSEB was in touch with GAIL, NTPC
and Petronet. Stage-I of RGCCPP is meant only for Kerala while
Stage-II is being envisaged as a Regional Project.
� TNEB had informed that they had not taken any stand regarding
availing power from this project due to domestic gas aspects. Kochi-
Bangalore gas pipeline had not materialized due to RoW issues while
Kochi-Kayamkulam pipeline was still in the preliminary stages.
Severe RoW issues existed in Kerala and elsewhere. Long term price
fix on RLNG for 15-20 years needed to be worked out. Hedging may
need to be ensured for Forex variations. It was also not clear
whether ICB had been invited and on what basis 16 dollars price had
been discovered.
� KPTCL had stated that they were also yet to take a firm view on this
project.
7.1.2 In the Meeting, MS I/c, SRPC informed that TCC had noted the following:
� NTPC had stated that any further development could take place only
after signing of the PPAs. NTPC was also awaiting the response from
Tamil Nadu. It would be difficult to predict the future rates of gas in
the future as well as the likely exchange rate. Rate of `9.12 per unit
furnished in the earlier meeting was indicative only and prevalent at
that time.
� TN had stated that they would furnish their response shortly.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 22
7.1.3 Director (Tr.), KPTCL informed that considering power availability in the state
during the next 5-10 years as well as the merit order, the management had
taken a decision that this costly power, as on date, was not required.
7.1.4 Chairperson, SRPC & CMD, APTRANSCO suggested that NTPC may try to bring
down the cost. However, he added that in perspective, any decision should
also be based considering whether ‘lack of power’ was costly or ‘costly’ power
was costly. It was well known that shortage of power had a cascading effect
on the economy.
7.2 NTPC- Kudgi TPS Stage-I (3x800 MW)
7.2.1 A coal based power plant of 2,400 MW installed capacity at Kudgi in Karnataka
is under construction by NTPC at an approved investment cost of about
`15,166 Crores.
7.2.2 In the 21st
/ 22nd
SRPC Meeting, the following had been noted:
� CEO, RECTPCL vide letter dated 24th
January 2013 had intimated that
the Empowered Committee had recommended to go ahead with the
competitive bidding process and RECTPCL had already initiated the
bidding process for selection of developer for the Kudgi ATS.
� PGCIL had said that with Kudgi-Narendra line in place, evacuation
from 1st
unit of Kudgi TPS would be ensured. The line from Kudgi –
Kudgi (PG) was extremely short (around 8 Kms) and should be
possible to be in place.
� SRLDC had stated that with Kudgi-Narendra line, effective
evacuation of Kudgi power may not be possible and hence the
Narendra-Kolhapur line should also be in place.
� NTPC had informed that the first unit was likely to be commissioned
with best efforts during June 2015 even though the commitment to
Government was March 2016 (CoD). The second unit was scheduled
after 6 months. Boiler for Unit-I had reached second tier, main PH
columns were under erection, chimney had reached zero meter and
other construction activities were progressing as per schedule.
� It was noted that three lines viz Kudgi-New Kudgi, New Kudgi-
Madhugiri, and Madhugiri-Bidadi were coming through the TBCB
route. Kudgi-New Kudgi line was likely to come up matching with
the commissioning of first unit. Narendra – Kolhapur and Narendra-
Kudgi lines were being executed by PGCIL and would come up by
commissioning of the first unit.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 23
� KPTCL had informed that for the purpose of startup power to Kudgi,
LILO of 220 kV Basavana Bagewadi-Narendra line was being carried
out.
� PGCIL had also stated that full evacuation of the power with only the
limited lines available may not be ensured. It would be subject to
the margins available in the grid.
� SRLDC had reiterated that there could be evacuation problems for
800 MW with only these two lines in operation, in case margins were
not available.
7.2.3 In the Meeting, MS I/c, SRPC informed that TCC had noted the following:
� Unit-I synchronization would be during September 2015 and Unit-II
after 4 months i.e. January 2016.
� Supply of coal for the initial period had been tied up with Pakri
Barwadih Captive mines of NTPC. Recently, two more mines had
been allocated but it would take some time to develop the mines.
� Mode of coal transport could be entire Rail or Sea cum Rail.
� The progress of the project is at Annexure-XIII.
� PGCIL had stated that the commissioning schedule needed to be
noted since the lines through TBCB route had been given
compressed time schedules.
7.2.4 On a query by Chairperson, SRPC & CMD, APTRANSCO about availability of
coal for this project, RED, NTPC informed that during the initial stages,
coal would be availed from Pakri Barwadih mines. It could take some
more time to develop two other allotted mines. He assured the
beneficiaries about the comfort level with regard to coal supply.
7.3 NLC-Neyveli TS-II Expansion (2x 250 MW)
7.3.1 In the 22nd
Meeting of SRPC, the following had been noted:
� NLC had earlier filed a petition in CERC (Petition No.15/MP/2013)
seeking Commission’s permission to maintain status-quo for
injection of infirm power and drawal of power for commissioning
activities under UI mechanism till declaration of COD or 31.08.2013
whichever is earlier.
� KSEB had stated that the commissioning of NLC-II Expansion project
cannot be delayed continuously as it would affect the beneficiaries.
It was also stated that the infirm energy shall be accounted only at
the actual variable cost of generation considering the following:
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 24
� Due to power shortage prevailing in the Southern grid, UI
rate is usually much higher than the variable cost of NLC
TPS-II Expansion project. Hence, allowing NLC to inject the
infirm energy at a rate much higher than variable cost may
act as deterrent for early commissioning of the project.
� Hon’ble CERC vide order on Petition No.250/MP/2012 had
ordered that UI is established strictly as a mechanism for
maintaining grid security.
� TANTRANSCO had stated that due to prolonged delay, SR grid is
being deprived of 500 MW. Hence, NLC may be insisted to
commission the units at the earliest at least before forthcoming
summer months. Further, NLC have filed a petition before Hon’ble
CERC anticipating further delay and seeking time extension upto
November 2013 for the purpose of injection of infirm power.
� NLC had intimated that the issue regarding early commissioning was
being followed up at the highest level with M/s. BHEL. This plant
had been included in the MoU parameters of M/s. BHEL. Refractory
dismantling works were currently under progress. The project was
already being reviewed by MoP, Ministry of Coal, Ministry of Heavy
Industries, CEA & Government of Tamil Nadu. CoD of Unit-I was
expected to be during September 2013 and Unit-II by December
2013.
7.3.2 Para 13 & 14 of Hon’ble CERC Order dated 04.09.2013 in respect of NLC TPS-II
Expn. is reproduced below for kind perusal:
“13. It is noticed that the Commission in its order dated 2.11.2012 had
allowed extension of time upto 15.2.2013 for injection of infirm
power from the project considering the special circumstances of the
case because of the new technology adopted by the petitioner. In the
instant case, the delay appears to be on account of re-designing of
coil support structures that had failed during load raising,
completion of design of the supporting structures inside FBHE and
manufacturing and erection of coils and support structures in
Fluidized Bed Heat Exchangers. We also notice that the petitioner
had faced similar problems in one of its generating station namely,
Barsingsar TPS (2x125 MW) which is based on CFBC technology
wherein the main plant package had been supplied by M/s BHEL.
Considering the factors in totality and due to unforeseen
circumstances, the petitioner is allowed to inject infirm power into
the grid for testing including full load testing till declaration of COD
or 30.11.2013, whichever is earlier. However, the extension of time
allowed for injection of infirm power into the grid shall not entitle
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 25
the petitioner for any increase in IDC and IEDC due to delay in
declaration of COD from the scheduled COD or any other
benefit/relaxation of availability or efficiency norms.
14. As the petitioner has submitted that the design change is required in
the supporting arrangement of FBHEs, the petitioner should also
consider recourse to action against the contractor as per agreement
for the delay, in accordance with the provisions, if any, of the
contract. This would also address the concern of the respondents by
way of reduction in the capital cost of the project.”
7.3.3 In its submission before Hon’ble CERC, NLC had stated that they were hopeful
of declaring COD by January 2014. However, some element of delay is
anticipated since the design was yet to be tested. NLC had also sought
maintaining status quo in the injection of infirm power under UI mechanism
till 31st
March 2014 or declaration of COD, whichever is earlier.
7.3.4 TANTRANSCO vide letter dated 25th
September 2013 (Annexure-XIV) had
stated that NLC should be advised to commission the units at the earliest, at
least before forthcoming summer months.
7.3.5 In the Meeting, MS I/c, SRPC informed that TCC had noted the following:
� Modified Coils had reached site and erection works were in full
swing. M/s BHEL was planning to achieve full load by January 2014.
BHEL & NLC had jointly formed different teams for supply & erection
and each activity had been planned meticulously.
� CoD of Unit 1 was expected during January 2014 and Unit 2 by
March 2014.
� Progress status had been reviewed recently in the Review Meeting
with participation of higher management of M/s BHEL.
� KPTCL had expressed serious concern over the delay in
commissioning of the units which was seriously affecting the power
procurement plan of the states.
� TANTRANSCO had pointed out that the transmission charges for the
ATS were being borne by the Constituents.
� SRLDC had noted that the generation from the unit would be helpful
during the proposed shutdown of Talcher-Kolar HVDC link and had
requested NLC to expedite the unit commissioning.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 26
7.3.6 Chairperson, SRPC & CMD, APTRANSCO requested NLC to expedite and
commission the units at the earliest.
7.4 NLC - New Thermal Power Project (2x 500 MW) at Neyveli
7.4.1 NLC had proposed to construct a new lignite based Thermal Power Project of
2x500 MW capacity at Neyveli, as a replacement for the existing and old
Thermal Power Station-I of 600 MW capacity at an estimated cost of `5596
Crores. The project was likely to take 40 months after PIB approval and was
targeted to be commissioned in 2014. The beneficiaries of Southern Region
had signed the PPA. The sanction of Government of India for the project had
been received vide letter dated 9th
June 2011.
7.4.2 The following had been noted till 22nd
meeting of SRPC:
� TN had stated that the entire power from this project should be
allocated to TN as in the case of Simhadri-I which had been allocated
to AP.
� Puducherry had informed that Hon’ble Chief Minister had written to
MoP seeking more allocation and the same was under the
consideration of CEA.
� A Meeting had been held on 11th
January 2012 at New Delhi
regarding allocation of additional power to Puducherry from Neyveli
New Thermal Power Project (NNTPP). TANGEDCO was requested to
confirm their view point on permanently allocating about 53 MW
from its share of NNTPP. However, the exact quantum of power
could be mutually decided by Government of Tamil Nadu & UT of
Puducherry. The allocation of share to other States would remain
unchanged. TANGEDCO had informed that they would furnish their
comments after consultation with the management.
� NLC had informed that refloating of tenders was carried out on 25th
September 2012.
� Tamil Nadu had informed that the additional power sought by
Puducherry could be made available from the unallocated power of
the Station.
� NLC had intimated that bid evaluation was under process. Unit-I was
scheduled to be commissioned by March 2017 and Unit-II by
September 2017.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 27
7.4.3 In the Meeting, MS I/c, SRPC informed that TCC had noted the following:
� Tendering activities had been completed and Order would be placed
by 1st
week of November 2013. Due to litigation issues with earlier
bidder, tendering activities had got delayed. CoD of Unit-I & Unit –II
was expected by October 2017 & April 2018 respectively.
� PGCIL had stated that firm commissioning schedules were required
to be communicated to Empowered Committee since ATS was to
come through the TBCB route. LTA had already been granted to NLC
New Thermal Power project.
� TANTRANSCO & NLC would mutually resolve issues relating to land
for the proposed 230 kV substation at Neyveli.
7.4.4 SRPC noted the above.
7.5 NPCIL-Kudankulam Nuclear Power Project (KKNPP) Stage-I (2x1000 MW)
7.5.1 In the 20th
Meeting of TCC held on 1st
February 2013, NPCIL had informed that
fuel loading had been completed. Clearance from Regulators was to be
obtained at various stages. Unit-I was expected to be synchronized by 2nd
/3rd
week of March 2013 with initial generation of 200 MW which would go upto
1000 MW in one month time. CoD of Unit-II would be after 6-8 months from
the CoD of first unit.
7.5.2 In the 21st
Meeting of SRPC held on 2nd
February 2013, KKNPP had informed
that nuclear fuel loading had been completed on 1st
October 2012. Hydro test
was going on. Clearance for criticality was expected by end of February 2013.
Stage-wise clearance was to be obtained from the Regulator subsequently.
7.5.3 In the 22nd
Meeting of SRPC held on 18th
May 2013 the following had been
noted:
� KSEB had stated that delay in commissioning of KKNPP, brings in
serious embarrassment in development in Kerala’s power sector.
Early commissioning and achieving full load as early as possible was
required in view of S1-S2 congestion.
� NPCIL had informed that the station was poised for injecting power
from June 2013. However, as per the recent directives of Hon’ble
Supreme Court, safety measures of the plant were to be reassessed
by AERB and other regulatory agencies. There could be slippage of
about one month in commencement of generation. As per the
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 28
present position, the reassessment of the safety measures
especially by AERB was likely to be completed by mid-June 2013
after which, the reactor would go critical. The comments on Draft
PPA had been received only from Karnataka & Puducherry. It had
been requested other beneficiaries also to expedite their
comments, so that the PPA could be signed.
7.5.4 A Meeting had been held at Kudankulam on 22nd
July 2013 with participation
of officers from NPCIL, TANTRANSCO, PGCIL, POSOCO, KSEB and SRPC
Secretariat to review the preparedness for synchronizing Unit 1 which had
attained criticality. A number of Measures were identified in that Meeting.
7.5.5 TSS, KKNPP vide letter dated 19th
August 2013 had informed that KKNPP Unit-I
would be ready for synchronization by end August 2013.
7.5.6 In the Meeting, MS I/c, SRPC informed that TCC had noted the following:
� Unit-I had been test synchronized on 22nd October 2013 with about
160 MW generation and was subsequently taken out from the grid
for statutory checks. Unit-I was likely to be resynchronized by
26th
October 2013.
� Generation level would be increased to 400 MW and subsequently
to 500 MW which was presently the approved quantum of AERB.
� Power level would subsequently be increased to 1,000 MW within
one month after obtaining AERB approval.
� Unit-II would be synchronized after about 6 to 8 months.
� ED, SRLDC had stated that GT Tap position should be changed to 400
kV before resynchronization of the Unit. This was in accordance with
the deliberations in the Meeting held at Kudankulam on 22nd
July
2013. In case the tap position is not changed, three lines (out of four)
may be required to be kept open to contain over voltage. Evacuation
of power if carried out through a single line would only lead to
considerable reduced reliability.
� NPCIL had informed that AVR settings were to be tuned and tap
could be changed subsequently. NPCIL would study this matter
further and come out with the course of action. It had again
requested that the unit be allowed to resynchronize with the existing
tap position.
� TCC had placed on record the appreciation of NPCIL in
commissioning of the KKNPP unit despite various challenges faced
during the course. It had also suggested that issues relating to GT
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 29
tap position needed to be addressed by NPCIL in the interest of
system security.
MS I/c also informed that Unit-I had been resynchronized at 21.43 Hrs on
25.10.2013.
7.5.7 Chairperson SRPC suggested that the technical issues such as tap position etc
be resolved at the earliest.
7.5.8 SRPC noted the above.
7.6 BHAVINI- Kalpakkam PFBR (500 MW)
7.6.1 Till 22nd
Meeting of SRPC, it had been noted that:
� BHAVINI had informed that the systems in the plant were getting
commissioned. Fuel loading was expected by end 2013 and
generation expected by September 2014 after completion of various
tests.
7.6.2 In the Special Meeting of TCC held on 21.08.2013, the issue regarding
commissioning of 230 KV Kalpakkam-Kancheepuram D/C line under Kalpakkam
PFBR Scheme raised by BHAVINI vide letter dated 12th
July 2013 was
considered. The following had been noted in this regard:
� The target dates of commissioning of Kudankulam units as well as
the BHAVINI unit have been delayed on number of occasions.
Projects were behind original schedules envisaged and this was
adversely affecting the planning process of the SR constituents.
There was also a 230 kV cable (not for evacuation) interconnecting
MAPS and BHAVINI S/S apart from four 230 kV lines.
� TCC had opined that firm commitment from BHAVINI was required
to assess the load generation balance accurately. Further the asset
i.e. Kancheepuram S/S should be put in use at the earliest. It was
also noted that four 230 kV lines were already in place to evacuate
BHAVINI generation and Kancheepuram S/S was being followed up
by TANTRANSCO on priority basis. With the commissioning of
Kancheepuram S/S, full evacuation system for PFBR would be in
place.
� ED (Operation), BHAVINI had informed that the target date for
commissioning of the unit was March 2014.
7.6.3 In the Meeting, MS I/c, SRPC informed that TCC had noted that the target date
of commissioning of the unit was March 2014. TANTRANSCO had informed
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 30
that tender in respect of Kancheepuram S/S had been finalized and the
substation was expected to be ready by September 2014.
7.6.4 SRPC noted the above.
7.7 NTECL - NTPC & TNEB Joint Venture - Vallur STPS (3x 500 MW)
7.7.1 The following had been noted till 22nd
Meeting of SRPC:
� Unit-1 (500MW) was declared under commercial operation with
effect from 00:00 Hrs of 29th
November 2012.
� In the OCC Meetings, SRLDC has brought to attention about the non-
performance of RGMO by NTECL Vallur Unit-I. NTECL Vallur had
earlier confirmed the RGMO implementation in the 81st
OCC
Meeting.
� NTPC had informed that Unit-II had reached full load and CoD would
be during June 2013 while CoD of Unit-III was expected during
February 2014.
� SRLDC had stated that RGMO should be in place before CoD
declaration for Units II & III. Unit-I was showing RGMO response in
certain instances. The graph furnished in last OCC meeting was for
output with respect to speed which needed to be furnished for
frequency with respect to output. It was also pointed out that the
period of 6 months allowed from commissioning to CoD was
basically for testing of various loops etc. Only after that, the CoD
should be declared.
� NTPC had observed that the auto loops get tuned over a period of
time. Putting in CMC mode was possible after operation in different
conditions. Any unit needed to run for at least one or two months
before putting the loops in auto mode. As per CERC norms, they had
time upto August 2013 to declare the CoD. However, all efforts
would be made to enable the RGMO features before CoD.
� SRLDC had pointed out that there was inadequate coal even for Unit-
I. Unit-I was thus being run at full load only during the peak hours.
� NTPC had informed that the MoU for Unit-II was to be signed with
MCL. A visit by MCL to inspect the readiness of Unit-II was also due.
MoU quantity was only for about 50% of the required quantity.
Blending with imported coal would be carried out, however there
would still be a shortfall. He added that blending upto 30% could be
carried out.
7.7.2 Subsequently, Unit-II (500MW) was declared under commercial operation with
effect from 00:00 Hrs of 25th
August 2013. In the 87th
OCC meeting held on
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 31

September 2013, SRLDC had expressed concern over the commissioning
of NTECL unit without fulfilling the conditions stipulated in the Operating
Procedure. The 72 hours Full Load Test had not been carried out, also copy of
PPA as stipulated in IEGC was not made available. It was also noted that Unit
II had faced a number of forced outages after declaration of the COD.
7.7.3 NTECL had informed that FSA for Phase I (2x500 MW) had been signed with
MCL on 24th
July 2013. FSA for Phase 2 (1x500 MW) of NTECL had also been
signed on 30th
August 2013.
7.7.4 In the Meeting, MS I/c, SRPC informed that in the TCC Meeting NTPC had
informed that Unit-II had been put under RGMO. Boiler light up of Unit-III had
been completed and steam blowing was scheduled during November 2013.
Synchronization of the unit was expected during February 2014.TCC had
suggested that the detailed programme/activities of commissioning of Unit-III
be furnished by NTECL.
7.7.5 Regional ED, NTPC assured that any mandatory compliance would be ensured.
7.8 NLC & TNEB Joint Venture at Tuticorin (2x 500 MW)
7.8.1 The following had been noted till 22nd
Meeting of SRPC:
� NLC had informed that orders had been placed on M/s. BHEL and it
was a coal based project and was a new area for them. Considering
the schedule of 40 months & 45 months from LOA signing i.e.
28.01.2009 units I & II were scheduled to be commissioned during
August 2012 & October 2012 respectively.
� TN had informed that Hon’ble Chief Minister, Tamil Nadu had
addressed to Hon’ble Prime Minister seeking revision of allocation
from this project. Tamil Nadu being the Home State was entitled to
get 75% of allocation from this project.
� NLC had informed that the likely CoD of the first unit would be in
December 2013 and another unit in March 2014. There was about
15 months delay in the project. M/s. BHEL had committed to
maintain the commissioning schedule of December 2013 & March
2014 for Unit I & Unit II respectively.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 32
� PGCIL & SRLDC had stated that the firm schedules of power injection
should be furnished by NLC as it would impact the TTC/ATC
computations.
7.8.2 In the Meeting, MS I/c, SRPC informed that in the TCC Meeting , NLC had
informed that progress of this project had also been reviewed in the recent
Meeting chaired by Secretary (Coal) with participation of higher management
of M/s BHEL. CoD of Unit-I was expected by February 2014 and Unit-II by May
2014.
7.8.3 SRPC noted the above.
7.9 Krishnapattanam UMPP (6x660 MW)
7.9.1 The following had been noted till 22nd
Meeting of SRPC:
� The project had been awarded to Reliance in the year 2007. The
initial configuration of 5x800 MW was subsequently revised to 6x660
MW with CERC approval. LOI had been placed with M/s. Shanghai
Electric Corporation.
� Maharashtra was yet to enter into PPA with CAPL while the other
beneficiaries had signed the PPA.
� The generation developer had stopped the works at site and the
project may get delayed.
� In the 19th
SRPC Meeting, APTRANSCO had informed that APSPDCL
the lead procurer had tried to encash the bank guarantee. However,
Reliance had approached Hon’ble Delhi High Court and obtained
stay. Hearing on the petition was again held on 31st
May 2012. The
Hon’ble Court had reserved the judgment on the matter. The
present developer could be recommended for cancellation. SRPC
may have to approach MoP for entrusting this project to some other
developer.
� PCKL had informed that under the leadership of AP all the procurers
had adopted a tough stand. Concerted action had been taken and
once the stay was vacated the bank guarantee could be encashed.
They were also ready with the Caveat in this regard. After encashing
the BG, future course of action could be decided as per the terms of
PPA. Since bidding route was adopted, there was no scope for
revision of the prices and Reliance should have had proper back to
back arrangement for coal supply.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 33
� KPTCL had opined that the matter regarding cancellation could be
taken up with MoP so that the associated legal issues could also be
examined by them.
� APTRANSCO had informed that the issue regarding encashment of
bank guarantee was before the Division Bench.
� In the 21st
SRPC Meeting APTRANSCO had informed that they had
conducted a meeting with the procurers. The consensus was to go
ahead as per PPA. However, it was also learnt that the developer
had approached CERC.
� KPTCL had stated that there were certain observations on admission
and that developer had to come back in this regard. The case was
still going on in Delhi High Court.
� In the 22nd
Meeting, APTRANSCO had stated that matter was still
pending before the Division Bench of Delhi High Court regarding
termination of the contract. CAPL petition regarding revision of
tariff was also pending before Hon’ble CERC.
7.9.2 In the Meeting, Chairman, TANTRANSCO enquired about the status of case in
Delhi High Court and CERC. He added that this project should not be allowed
to lapse. He therefore suggested that being the lead procurer, AP may kindly
take up the issue appropriately.
7.9.3 Director (Tr.), KPTCL informed that it was learnt that though the stay has been
vacated, Reliance had approached the Bench of Hon’ble Delhi High Court. He
noted that in earlier Meetings, the other states had authorized AP to proceed
on this matter.
7.9.4 APPCC informed that hearings were still going on in Hon’ble Delhi High Court.
7.9.5 It was agreed that AP on behalf of other beneficiary states would take up the

7.12 MS I/c , SRPC informed that in TCC meeting APPCC had raised concern on the
burden of sharing of transmission charges of ATS in event of delay of
commissioning of the project by the Generator.
8. OPENING OF LC DUE TO DELAYED UI CHARGES PAYMENT
8.1 SRLDC had informed in the Commercial Sub-Committee & OCC Meetings that
APTRANSCO, TANGEDCO, LKPL and SEL had to open / enhance LC for delayed
payment of UI charges. The details are as furnished below:
APTRANSCO `247.50 Lakhs
TANGEDCO `2635.00 Lakhs
LKPL `2.44 Lakhs
SEL `17.10 Lakhs
8.2 SRPC Secretariat vide letter dated 24th
September 2013 had requested the
concerned utilities that opening / enhancement of the LC may be expedited.
8.3 In the Meeting, MS I/c, SRPC informed that the following had been noted in the
TCC Meeting:
� APTRANSCO had informed that they had already opened LC for
`2.475 Crores.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 36
� TANTRANSCO had stated that they had taken up this matter with
Hon’ble CERC and were awaiting orders. Enhancement of LC amount
as computed by SRLDC may not be required. It was pointed out that
since the overdrawal by TN had considerably reduced, the need to
open LC for the huge amount did not arise. TN would comply with any
directions from Hon’ble CERC in this matter.
� SRLDC had informed that defaulting constituents were being followed
up on the matter of opening / enhancement of LC. Status, in this
regard was also being reported to Hon’ble CERC. The proper recourse
would be to approach Hon’ble CERC through a petition for any
redressal. However, in the meanwhile the LCs for the above amounts
had to be opened, since LC amounts had been worked out only as per
the Regulations. Failure to open the LC would amount to
noncompliance of the provisions of UI Regulations.
� Concerned utilities had been requested to kindly expedite
opening/enhancement of LC for delayed payment of UI charges.
8.4 Chairman, TANTRANSCO stated that there may be no point in opening of LC with
enhanced limits, in the present restricted band of operation. The frequency band
had also been narrowed and quantum of over drawals had also come down.
Hence, insisting on opening of LC with enhanced limits, based on past historical
data may not be correct.
8.5 Chairperson, SRPC opined that LC requirement may need to be reviewed based on
the prevailing conditions.
8.6 ED, SRLDC stated that LC requirement was in line with CERC Regulations. He said
that Hon’ble CERC would need to be approached through a Petition for any
amendment in the Regulations.
8.7 After deliberations, Chairman TANTRANSCO stated that they would approach
Hon’ble CERC in this regard.
9. IMPLEMENTATION OF RRF MECHANISM
9.1 A Meeting was conducted on 25th
September 2013 in SRLDC/SRPC, Bangalore to
discuss various issues relating to RRF Mechanism. NLDC, New Delhi had
participated in the Meeting through VC. Following issues had been discussed in
the Meeting:
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 37
� SRPC had brought to attention that data in respect of only one pooling
station in Karnataka had been received for the RRF Account issued on
24th
September 2013. AP had not furnished the data so far. AP
informed that the Solar and Wind Generators in AP had not fixed the
Coordinating Agency.
� NLDC had stated that SLDCs should coordinate with the Coordinating
Agency so that the schedule and actual data are made available within
the time frame stipulated in the Regulations.
� NLDC had also expressed deep concern that the list of Coordinating
Agency and other details had not been made available to SRLDC.
SLDCs expressed that the Wind Generators in certain cases were not
in a position to come to a consensus regarding fixing of Coordinating
Agency for the purpose of scheduling, metering and energy
accounting etc.
� NLDC and SRPC had stated that SLDCs should initiate urgent action in
this regard. SLDCs should come out with a white paper within a
period of 7 days. This white paper should contain all details regarding
number of pooling stations, Coordinating Agency etc. and also the
status of RRF implementation in the State. Further, SLDCs should take
up the matter with SERC/CERC in case the Wind Generators are
unable to come to a consensus. It was noted with concern that
though the RRF mechanism had come into effect from 15th
July 2013
the Generators had been unable to come to a consensus regarding
Coordinating Agency.
� Wind Generators had informed that in certain cases it had been
observed that there is mismatch between schedule data furnished to
SLDC and the schedule data considered in the RRF account issued by
SRPC Secretariat. SRPC clarified that the RRF account was prepared
based on the schedule and actual data received from SRLDC. SRLDC
informed that they had processed the data given by SLDCs and
forwarded the data to SRPC. SLDCs were requested to look into the
issue. TANTRANSCO informed that there were certain issues due to
wind backing down conditions during high frequency.
� It was noted that in certain blocks though the actual injection was
furnished there were no corresponding schedule data. It was decided
that the accounting will be carried out only if both the schedule and
actual injection data are furnished. No assumptions in this regard will
be made by SRPC Secretariat. SLDCs were requested to ensure that
the data submitted by them to RLDCs was complete in all respects.
� NLDC had stated that disbursement through RRF mechanism had
presently been stayed by Hon’ble Court. However, all the concerned
utilities were requested to furnish concerned details such as bank
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 38
account details etc. to SRLDC at an early date. SRLDC in turn would
furnish the same to NLDC.
� SLDCs were requested to carry out data validation checks to ensure
that the actual injection data furnished by them to SRLDC is accurate.
9.2 In the Meeting, MS I/c, SRPC informed that the issue had been deliberated in the
TCC Meeting and the following had been noted:
� States had been requested to submit the “White Paper” containing
information relating to Pooling Stations, Coordinating Agency etc. as
agreed in the Meeting held on 25th
September 2013.
� It had also been suggested to the States to jointly identify common
issues such as those relating to treatment of schedule during backing
down and appropriately take up the same with Implementing
Agency/SERC/CERC.
� Need for timely submission of the data for preparation of the RRF
accounts had also been emphasized.
9.3 Chairperson, SRPC & CMD, APTRANSCO enquired whether the issue was related
to comprehension of the Regulations or to the availability of data.
9.4 Chairman, TANTRANSCO stated that it appeared that the mechanism had been
wrongly designed and was against promotion of renewable energy. TN had about
7,000 MW of wind energy of seasonal nature, the generation being maximum
during May to September. There were huge intraday variations between 100-
3000 MW. While +/- 30% variations for wind were being allowed, with respect to
TN drawal only 100 MW band was being allowed. Fundamental flaw in this regard
had also been informed to Ministry of Power. Proposed tightening of the
Frequency Band between 49.95-50.05 Hz, with 7,000 MW wind generation may
not be very viable. In Tamil Nadu, about 250 MW only of WF were covered under
the new Regulations. There were also issues related to Temporary/Permanent
Connectivity. The RRF mechanism had also imposed huge commercial burdens on
the Discom, since payments were to be made w.r.t. Reference Rate of `5. There
were issues relating to transmission also, since the wind mills were of locational
nature. He stated that they would approach Hon’ble CERC in this regard.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 39
9.5 Chairperson, SRPC & CMD, APTRANSCO suggested that TN may kindly take the
lead in this regard. Chairman, TANTRANSCO agreed to file a petition before
Hon’ble CERC.

NO. 250/MP/2012) & GRID SECURITY EXPERT SYSTEM (GSES) (PETITION NO.
265/MP/2012)
10.1 Automatic Demand Management Scheme in line with clause 5.4.2 (d) of the IEGC
was to be provided by all the constituents by 01.01.2011.
10.2 With respect to Petition (No. 250/MP/2012) Hon'ble CERC had issued an order
dated 14.01.2013 & RoP dated 07.03.2013. Para 4 of the RoP is reproduced
below:
“In response to Commission`s query whether both Grid Security Expert
System (GSES) and Automatic Demand Management scheme are
required or it may be duplication of facilities, the representative of the
NRLDC submitted that both the schemes are separate and need to be
implemented with the GSES would be operated from SLDC and RLDC
level and would be at higher voltage level, Automatic Demand
Management Scheme (ADMS) will be at 11 kV, 33 kV feeder level. The
objective of ADMS is to control the demand as per availability and at
the same time objective of GSES is for action when action by ADMS is
not sufficient.”
10.3 With respect to Petition (No. 265/MP/2012) Hon'ble CERC had issued RoP on 10th
January 2013. Subsequently a Special TCC Meeting was held on 11th
and 12th
February 2013 and the views were communicated to Hon’ble CERC. Hon’ble CERC
had passed an Order dated 5th
March 2013 in this regard. Para 8 (a) & (b) are
reproduced below.
“8. The Commission directed to CTU to submit the following on affidavit by

be implemented.
� The concern about the State Utilities would also be put up to NPC.
10.6 PGCIL vide letter dated 27th
May 2013 addressed to the utilities had stated that
the GSES scheme had been proposed based on the feeders identified in the
document forwarded by NLDC. The feeders indicated had been identified by
SRLDC. In case of any observations on these feeders, the same could be discussed
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 41
with SRLDC. PGCIL had also sought the information on priority. In the Special TCC
Meeting held on 24th
June 2013, it had been agreed that the status be brought to
the kind attention of Hon’ble CERC. As agreed, the matter had been appraised to
Hon’ble CERC vide SRPC letter dated 26th

12. SYNCHRONISATION OF SR WITH NEW GRID / 765 kV RAICHUR-SHOLAPUR LINES
12.1 765 kV Raichur-Sholapur lines are expected to be commissioned in the first
quarter of 2014. The commissioning of these lines would enable synchronous
inter connection of SR Grid with NEW grid. A meeting chaired by Chairperson, CEA
was held in CEA on 9th
September 2013 to discuss the issues related to
synchronization of Southern Region (SR) grid with NEW Grid (Minutes enclosed as
Annexure-XVI). After discussion, the following had been concluded:
� Synchronization of SR with NEW grid would be subject to fulfillment of
the following :
� Implementation of recommendation of protection audit of
under frequency load shedding relays settings as per
National Power Committee
� Installation of Special Energy Meters and PMUs at
Sholapur and Raichur ends
� Design and implementation of SPS for Sholapur-Raichur
765 kV lines
� Review of SPS for Talcher-Kolar HVDC bipole.
� Testing of frequency response of HVDC controllers of the
Chandrapur btb, Gazuwaka btb and Talcher-Kolar HVDC
bipole links
� It was also underlined that the following measures should be
expedited for reliable operation of the National grid after
synchronization:
� Tightening of frequency band to reduce requirement of
balancing power
� Free Governor Mode Operation (FGMO)
� Mechanism for tight control on deviations from the
schedule and Area control error
� Primary response testing of generating machines
� Expeditious development of parallel corridors between SR
and NEW grid
� Testing of frequency response of all remaining HVDC
controllers.
� It had been agreed that the initial power flow on these lines will be
restricted to about 800 MW, which will be progressively increased to
2000 MW after commissioning of following transmission elements in
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 44
WR and SR. Further, no scheduled exchange of energy will be allowed
on Sholapur-Raichur 765 kV lines for first six months of synchronous
operation. Thus, if the first synchronization of SR with NEW grid takes
place by January, 2014, the LTA/MTOA allocations shall be made from
1st
July, 2014 onwards. Any delay in first synchronization beyond
January 2014, the effective start of LTA/MTOA shall be accordingly
delayed:

12.2 Copy of Detailed Note for synchronization of Southern Region grid with NEW grid
from Member (GO & D), CEA is furnished at Annexure-XVII.
12.3 Another Meeting was also held on 3rd
October 2013 in New Delhi regarding
determination of the Available Transfer Capability for 765 kV Sholapur – Raichur
lines. Utilities of SR had also participated in the Meeting.
12.4 In the Meeting, MS I/c, SRPC informed that the issue had been deliberated in the
TCC Meeting and the following had been noted:
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 45
� CEA vide letter dated 9th
October 2013 to CERC (Annexure-XVIII) had
suggested that amendments to Grid Code be notified by 30th
November 2013. Utilities would then get enough time to adjust their
operating practices in line with new frequency band. This would be
immensely helpful in the smooth integration of SR and NEW grids and
also in secure operation of the combined grid.
� TANTRANSCO had suggested that PGCIL and other concerned agencies
may accelerate the works, so that commercial scheduled power flow
on the lines would be available in March 2014 itself instead of July
2014 indicated presently. TN had added that power requirements
would be higher in March, being a summer month as against July
which would be a monsoon period. It was noted that as indicated in
the detailed note of Member (GO & D), a total of 18 critical elements
had been identified in NEW Grid and SR Grid which needed to be
commissioned on priority basis. Status of these elements was already
being monitored closely. Further, since two major grids were to be
tied, it was highly essential that adequate operational experience be
gained, prior to scheduled power flow on these lines.
� PGCIL had informed that Raichur-Sholapur circuit under TBCB route
could be slightly delayed. The issue regarding tying up of the SR grid
with NEW grid with single 765 kV line was being studied. They also
informed about the Turkish experience when it was to be tied to the
European grid. Considerable time of more than 11 months was taken
to gain confidence there. ED, SRTS-I had informed that severe RoW
problems existed in respect of Gooty- Madhugiri as well as Madhugiri-
Yelahanka lines, which were very critical. Forum had requested KPTCL
to use its good offices in resolution of the ROW issues.
� SRLDC had opined that it may not be desirable to synchronize SR with
the NEW grid with a single 765 kV line. On a query, PGCIL stated that
as a thumb rule, interconnection capacity needed to be about 10% of
the smaller grid capacity.
� PGCIL had informed that Raichur Substation would be completed by
January 2014 and focused attention was being given to other elements
also.
12.5 Chairman, TANTRANSCO suggested that Chairperson SRPC may kindly take up
with Ministry of Power to use its good offices to expedite the other line being
executed by Patel Engineering under TBCB route, so as to have both 765 KV lines
in place.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 46
12.6 Director (O), PGCIL informed that the line being executed by PGCIL would be ready
in all respects by January 2014. The other line being executed by Patel
Engineering was ahead in the month of May/June 2013 but currently stringing
works were not progressing as desired. He said that the line may thus be delayed
by about two months.
12.7 ED, SRTS-I, PGCIL informed that it was learnt that the TBCB line would be
completed by March 2014.
12.8 MS I/c, SRPC informed that it had been informed by POWERGRID that severe
RoW problems existed in respect of Gooty-Madhugiri as well as Madhugiri-
Yelahanka lines, which were needed to be addressed.
12.9 MD, KPTCL assured that KPTCL would extend necessary cooperation in this regard
and the issue would be taken up appropriately.
13. AUGMENTATION OF TALCHER- II TRANSMISSION SYSTEM

agreed that no extension could be granted to M/s. TTCL.
� TCC had recommended that TANTRANSCO as lead procurer would
initiate suitable action regarding filing of appropriate response etc.
� Chairperson, SRPC had observed that a resolution could be passed
that the construction of line be handed to PGCIL under ‘Urgency
Clause’.
� APTRANSCO had said that issues regarding Bank Guarantee also
needed to be examined.
� TNEB had opined that TTCL could first be informed that no extension
of time could be given. Consequently it could be recommended that
PGCIL may take up these works.
13.3 Subsequently, in RoP dated 09.07.2013 Hon’ble CERC had directed NKTCL and
TTCL to hold a Meeting with the Procurers of both projects within a period of two
weeks and file the outcome of the meeting before 30th

Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 49
� TANGEDCO had informed that Orders of Appellate Tribunal in this
regard were also awaited.
13.6 SRPC noted the above.
14. CONSTRAINTS IN TRANSMISSION SCHEMES FOR ISTS
RoW of 400 kV Mysore-Kozhikode D/C line
14.1 Till 22nd
Meeting of SRPC the following had been noted:
� PGCIL had stated that the line length was 260 Kms, of which 118 Kms
was in the Karnataka portion. Out of this 118 Kms, 63 Kms of the line
had been completed. Of the balance, 4.5 Kms was in the reserve
forest area, for which clearance had been obtained. 30.5 Kms was in
the coffee plantation and 20 Kms in paddy field areas. With the active
support and guidance of KPTCL & Government of Karnataka, PGCIL
was moving ahead. They had also met Chief Secretary, Government of
Karnataka a few days ago. The compensation as paid by KPTCL was
being followed, which was coming to approximately `1,500 per Coffee
Plant.
� PGCIL had informed that their advocate had suggested seeking certain
legal remedy. On a query from KSEB about completion of the line, it
was informed that if the remedy comes through, then by next year
summer, the line could be ready. PGCIL was putting in all-out efforts
in this regard.
� KSEB had stated that in the event of 400 kV Mysore- Kozhikode line
getting indefinitely delayed, construction of 400 kV line from
Madakkathara to Kozhikode be taken up urgently. It was also stated
that PGCIL be requested to frame an action plan for this proposal with
priority.
� PGCIL had informed that about 55 Kms stretch of the line was having
issues. Works had earlier been initiated under police protection but
suspended on account of the State Assembly Elections. A Meeting at
the highest level was likely to be held shortly. In case the issues were
resolved at the earliest, the line was likely to be completed by March
2014.
14.2 In the Meeting, MS I/c, SRPC informed that TCC had noted the following:
� PGCIL had informed that they had approached Hon’ble Chief Minister
of Karnataka in this matter. State Government had assured support
for the completion of the project. The works had been restarted four
times under Police protection but had to be stopped on account of
various reasons.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 50
� APGENCO had expressed concern that the schemes in power sector
were getting delayed due to a number of issues. Stringent directives
from the highest level were required in case the projects are to be
completed within the targeted time schedule. SRPC forum should
raise its concern in this regard.
� TCC forum had requested KPTCL to use its good offices for early
resolution of the issues so that the line could be commissioned at the
earliest. KPTCL had assured full cooperation for early completion of
the line.
14.3 ED, SRTS-II, PGCIL informed that 4-5 attempts had been made to start the works
under police protection. Except environmentalists and certain fringe groups, most
of the protests had been withdrawn. If a conducive environment was ensured,
the line could be completed at the earliest.
14.4 Chairman, TANTRANSCO requested MD, KPTCL to kindly look into the issue since
line completion would help ease S1-S2 congestion. This line had to be facilitated
so as to relieve transmission congestion in TN due to power flow to Kerala.
14.5 MD, KPTCL assured that they would extend support including at local
administration level to complete this line at the earliest.
15. TRANSMISSION CONSTRAINTS IN INTER-REGIONAL & INTRA-REGIONAL
TRANSMISSION SYSTEMS
15.1 In the 22nd
Meeting of SRPC the following had been noted:
� PGCIL had informed that the proposal for execution of Srikakulam
Pooling Station – Vemagiri Pooling Station 765 kV D/C line &
Khammam New – Nagarjunasagar 400 kV D/C line by PGCIL under
‘Urgency’ clause had not been agreed to. These lines would therefore
come under TBCB route. PGCIL expressed concern over delay in
commissioning of certain intra-State transmission lines executed by
State utilities. They added that unless downstream system was
coordinated, overall utilization of the system would be less.
� SRLDC had requested TANTRANSCO to furnish the plan and
commissioning schedule of Thiruvalam S/S & lines etc for study
purpose. TANTRANSCO agreed to furnish the same with a copy to
SRPC Secretariat. There would be constraints in evacuating
Krishnapattanam JV power since the TANTRANSCO Thiruvalam system
would not be in place and Nellore- Alamathy line would get
overloaded.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 51
� SRPC Secretariat had pointed out the details in respect of progress of
lines that were coming through the TBCB route were not available
with SRPC. PGCIL was requested to share the information in this
regard. PGCIL agreed to furnish the information available.
� APTRANSCO had pointed out that 1st
Unit (800 MW) of
Krishnapattanam TPS was expected by October/November. The lines
in AP system would also get ready by September. However, the line
from Chittoor to Thiruvalam, as well as Thiruvalam downstream
needed to be coordinated and expedited to ensure proper evacuation
of power. TN to ensure that their system was ready at least by
January 2014. Second unit of Krishnapattanam TPS was expected to
come by January 2014.
� TN had informed that immediate action had been taken after the last
SRPC meeting regarding Thiruvalam S/S. Land had been acquired
under ‘Urgency Clause’. Parallely tendering activities were taken up,
price bids were being processed and contract for 400 KV S/S was likely
to be awarded within 1-2 weeks. The schedule had been crashed to 1
year with incentive for early completion. Packages for associated lines
(`1,000 Crores) had also been floated and the award was likely next
month. TN would try to complete whatever maximum was possible
technically in the available time period.
� PGCIL had stated that in the future, Gujarat could have around 6,000
MW of surplus power. SR constituents could thus avail this surplus
power through an 800 kV HVDC link from Gujarat to a suitable landing
point in SR. The total cost of such a HVDC link could be `12,000
Crores. A dedicated metallic return path could be planned for this
HVDC link. A comprehensive view of the possible inter-Regional link
capacity was also required. The matter could then be taken up for
discussions in the Standing Committee on Power System Planning.
The STUs could come to PGCIL for discussions so that a
comprehensive plan could be worked out.
� It was agreed that the officers from STUs would meet at PGCIL Office,
to work out a comprehensive plan in this regard.
15.2 In the Meeting, MS I/c, SRPC informed that this issue had been deliberated in the
TCC Meeting and the following had been noted:
� TANTRANSCO had informed that order had been placed for
Thiruvalam Substation on 11th
October 2013 and works were in
progress. As a special case, incentive @2% per month was also being
offered for early completion.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 52
� SRLDC had stated that loads at Thiruvalam were also to be ensured by
TN for smooth evacuation of Krishnapattanam JV project. APTRANSCO
added that completion of downstream system in Thiruvalam would
also help ease the S1 – S2 congestion to a certain extent.
TANTRANSCO had informed that the downstream system at
Thiruvalam S/S were in progress and would match the substation.
� SRLDC had stated that total power of only about 1,500 MW could be
evacuated from NTECL Vallur and NCTPS-II. Since its ATS was not in
place, NCTPS would be required to back down in case of any
constraints (Schematic Diagram in Annexure-XIX). Evacuation of
power from Vallur and NCTPS through the existing transmission lines
would cause severe stress. TN Control Room should be instructed to
back down the generation in North Chennai, whenever there were any
line loading issues. Higher management intervention for this purpose
was not warranted. Also, for the proper evacuation of generation of
NCTPS, construction of the 400kV D/C NCTPS – SV Chatram, Alamathy
- S.V.Chatram & Alamathy – Thiruvalam lines were needed to be
expedited.
� TANTRANSCO had stated that the evacuation system was in the
advanced stage of commissioning and they would take appropriate
action during transmission constraints. Seven towers were pending in
respect of the 400 KV D/C Alamathy-S V Chatram line and that the line
would get commissioned by end November 2013. Suitable instructions
would be given to the Control Room regarding backing down
generation in event of line loading issues etc.
15.3 The schedule of commissioning of elements as furnished in the Meeting is as
follows:
Transmission Element Schedule Remarks
400 kV Chittoor-Thiruvalam December 2013 With best efforts & availability of bays at

� PGCIL had informed that firm schedule for commissioning of the
above elements would be furnished by the next SRPC Meeting.
� JSWEL vide letter dated 17th
October 2013 (Annexure-XX) had
requested that export of power from the JSW Complex at Torangallu
be also taken into account while finalizing inter-regional & intra-state
transmission elements in Karnataka. This would ensure that Utilities
in power deficit Southern Region were not deprived of `generation
capacity available in JSW Karnataka. In the meeting, JSWEL had
informed that they would bilaterally sort out the evacuation issues
with KPTCL.
� SRLDC had also observed that TANTRANSCO had not furnished the
progress of critical intra-regional elements included in the
Operational Feedback furnished by SRLDC. Some of the other states
had not furnished the time schedule for implementation.
� TCC had suggested that states may kindly furnish complete details in
respect of critical intra-regional elements identified in the
Operational Feedback furnished by SRLDC at the earliest.
15.4 Chairperson, SRPC & CMD, APTRANSCO informed that shortage of Bidders was
being faced for execution of lines and Substation etc in the State. This was mainly
on account of manpower and capability constraints. With such constraints, the
works were getting delayed. He added that the construction of the
Krishnapattanam-Chittoor line was being constantly reviewed.
15.5 Chairman, KSEB said that this was basically because of corporatization that had
happened in this sector. In the earlier scenario, there used to be small
contractors for execution of the works. However, presently in the Tariff Based
regime, there were a few ‘Big Players’ whose capacity was getting exposed.
Hence in the post reform scenario, this was to be viewed as a basic structural
issue.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 54
15.6 On a request from APTRANSCO, Chairman, TANTRANSCO assured that Thiruvalam
S/S and associated lines were on track and would be completed by the scheduled
dates. He also enquired about the status of the proposed HVDC link from Gujarat
to SR.
15.7 Director (O), PGCIL stated that during discussions in one of the WRPC meetings, it
had been noted that WR may be surplus by about 6,000 – 8,000 MW in another 5
to 6 years time. Hence, it had been contemplated to have a high capacity +/- 800
kV DC line from Gujarat to a suitable location in SR.
15.8 Chairman, KSEB suggested that SRPC may empower PGCIL to prepare the way
forward on this matter.
15.9 Chairman, TANTRANSCO suggested that CEA could be requested to convene a
Meeting to assess the transmission requirements that would be required to
ensure that surplus generation in Gujarat is available to the Southern States with
long term timeframe in consideration.
15.10 DGM, PGCIL informed that import of about 11,500 MW of power to SR had been
planned through various links such as Wardha-Hyderabad, Srikakulam-Vemagiri ,
Raichur- Sholapur besides the Raigarh – Pugalur HVDC link (4,000 MW). Recently,
the capacity of the Raigarh – Pugalur HVDC link had been suggested to be 6,000
MW. Hence, system for dispersal of the additional 2,000 MW of power beyond
Pugalur would be worked out and put up in the next Meeting of Standing
Committee. On top of this, in case requirement of additional Gujarat-SR HVDC link
was felt, the same could be worked out.
15.11 It was agreed that Chairperson, SRPC would take up with CEA with regard to the
proposed HVDC link from Gujarat to SR.
15.12 The status in respect of critical Intra Regional transmission system in the State
Sector is enclosed as Annexure-XXI.

� The existing 63 MVAR Reactors at Hyderabad & Narendra would be
maintained as Regional spare after refurbishment.
� It had also been suggested to utilize the 80 MVAR shunt reactor at
GMR Expansion Plant to contain HV issue at 400 kV Vemagiri.
16.4 In the Meeting, MS I/c, SRPC informed that in the TCC Meeting, the following had
been noted:
� Line reactor at Guttur S/S was required in addition to the bus reactor
and should also be in place.
� APTRANSCO had informed that M/s GMR had refused to keep the
reactor in Expansion Plant in service since the unit was not
commissioned due to gas unavailability. They had also informed that
there were commercial implications like guarantee and warranties
involved since the plant had not yet been handed over by the EPC
contractor.
� In the 36th
Standing Committee Meeting held on 4th
September 2013,
NPCIL had stated that 1x63 MVAR reactor at Kaiga had already been
installed. However, KPTCL had not installed the reactor at Guttur,
which was overdue. NPCIL had also stated that there was no space in
the switchyard to accommodate any additional reactor. NPCIL had
however been requested to examine the possibility of providing
additional reactor at Kaiga / replace the 63 MVAR with 125 MVAR.
� SRLDC had expressed concern over the delay in commissioning of the
reactors by KPCL/KPTCL. NPCIL had also expressed concern over non-
commissioning of line and bus reactors at Guttur S/S by KPTCL. KPTCL
had informed that the delay was on account of BHEL. However the
matter regarding supply/commissioning was being followed up with
BHEL and a meeting was scheduled to be held next week. The reactor
at Hoody would be shifted to Guttur on a priority basis and would be
commissioned within six months.
� PGCIL had stated that the line reactors of Raichur-Sholapur line could
be utilized as bus reactors for voltage management at Raichur, in case
the constituents agreed. This would be recommended after due
studies.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 57
� SRLDC had proposed that reactors at GMR & LANCO be used for
voltage regulation. The energy consumption on this account could be
accounted as Regional loss. APTRANSCO had informed that in case of
GMR, it was learnt that there were commercial implications like
guarantee and warranties involved since the plant had not yet been
handed over by the EPC contractor.
� TCC had recommended that the reactors at GMR & LANCO be used
for voltage regulation. The energy consumption on this account could
be accounted as Regional loss.
16.5 ED, SRTS-I, PGCIL informed that 765 KV reactor could be utilized for voltage
regulation at Nellore PS. They would come up with a concrete proposal in this
regard.
16.6 SRPC approved that the reactors at GMR & LANCO be used for voltage
regulation. The energy consumption on this account would be accounted as
Regional loss.
17. PROPOSALS TO RELIEVE CONGESTION IN S1 – S2 POWER CORRIDOR/ INTER-
REGIONAL CORRIDOR
17.1 Edamon-Cochin 400 kV line
17.1.1 KSEB had stated that completion of this line was essential for increasing the
import capability of Kerala and also for efficient evacuation. Construction of
this line had been held up due to severe RoW issues.
17.1.2 In the previous SRPC Meetings, the following had been noted:
� PGCIL had informed that adoption of original alignment for Edamon-
Cochin 400 kV line was confirmed. The line was likely to be
completed by December 2014 with best efforts. They were expecting
commitment and clearance from Kerala. KSEB had informed that a
policy decision from the Govt. of Kerala was awaited.
� KSEB had informed that lot of discussions were being held between
the farmers and Government to evolve some solution. The issue
was who would bear the additional financial commitment. It was
pointed out that PGCIL should make all efforts to solve the issue and
commission the asset at the earliest.
� PGCIL had stated that the ramifications of compensation locally in
any one corner of the country would have wide range of implications
globally. Issues could not be seen in isolation and a holistic global
view on these issues needed to be taken. It was stated that PGCIL
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 58
and other utilities were building more than 1,00,000 ckt kms of EHV
lines during the 12th
Five Year Plan. PGCIL alone was building more
than 60,000 Ckt Km of lines out of this. While the Line cost was
about Rupees One Crore per Km, the compensation amount itself
probably worked to about Rupees Three Crores per Km. In such a
scenario the cost would be very high and requested Kerala’s support
to complete the line. However, PGCIL was fully committed to build
this line. Discussions with State Government were under way.
� PGCIL had stated that additional compensation of bout `330-350
Crores was not viable. The matter had been discussed a number of
times with the State Government. Payment of additional
compensation would send wrong signals to various other projects of
PGCIL in the country. The material was lying unutilized since there
was no progress since past 5-6 years. Despite all efforts, it appeared
that PGCIL would be constrained to withdraw from the scheme.
� KSEB had expressed surprise that being CTU, PGCIL was suggesting
withdrawal and closure of the package which needed to be noted.
� PGCIL had suggested that KSEB may develop this line and maintain
as its own asset after taking over from PGCIL.
� Chairperson, SRPC had stated that 400 kV Edamon–Cochin was an
important link and considered investment had already been sunk in.
As noted, Government/local administration help was being given to
PGCIL to sort out RoW issues etc in AP. He therefore suggested that
PGCIL & Kerala should make one more effort to come out with some
viable solution. The local administration in Kerala should help PGCIL
in this regard.
� KSEB had informed that they would arrange another High level
Meeting with PGCIL to try to come out of the present impasse.
� Chairperson, SRPC had suggested that PGCIL with assistance from
KSEB/local administration may make attempts to resolve this issue
and put the same to next SRPC for decision.
17.1.3 In the Meeting, MS I/c, SRPC informed that in the TCC Meeting KSEB had
informed that a high level Meeting had been scheduled to be held on 28th
October 2013 on this matter.
17.2 400 kV Trichur-Kozhikode line (Madakkathara-Areakode)
The following had been noted till 22nd
Meeting of SRPC:
� KSEB had stated that this line had already been approved as Regional
System Strengthening Scheme. North Kerala would benefit as 400 kV
supply could be availed either from Udumalpet or from Mysore for all
the 400 kV substations in Kerala.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 59
� PGCIL had sought utilization of existing 220 kV Madakkathara-
Malaparamba-Areakode S/C feeder. In the 14th
SRPC Meeting, KSEB
had denied the possibility of surrendering the RoW of the KSEB line
since energy security of Malabar region was involved.
� KSEB had stated that 400 kV Madakkathara-Areakode line may be
termed as 400 kV Trichur – Kozhikode line. Multi circuit & multi-level
circuit was their requirement for surrender of corridor.
� PGCIL had informed that the line would be taken up after the
completion of 400 kV Mysore-Kozhikode line. The line was feasible
only if the existing corridor was surrendered by Kerala.
� KSEB had reiterated that the line could be taken up only after
commissioning of the 400 kV Mysore-Kozhikode line. PGCIL had been
requested to initiate the process so that construction could commence
immediately after 400 kV Mysore-Kozhikode line was commissioned.
18. COAL STOCK POSITION IN THERMAL STATIONS OF SOUTHERN REGION
18.1 The need for maintaining statutory coal stock position in all the thermal stations
at all times had been deliberated in various forum of SRPC.
Constituents/Generating Companies had been requested to please apprise the
Committee of the coal stock position in the thermal stations.
18.2 As agreed in the 22nd
SRPC Meeting, Chairperson, SRPC had taken up the matter
with Member (Traffic), Railway Board regarding nomination of an Officer from
Railways to represent in the SRPC forum. Subsequently, Railways vide letter dated
20th
June 2013 (Annexure-XXII) had nominated an Officer for this purpose.
Accordingly, a Meeting with MCL, Railways and Generating Utilities was held on
01st
October 2013 at Secunderabad (Minutes enclosed as Annexure-XXIII).
18.3 In the Meeting Director, MCL stated that MCL was geared up to meet the
requirements of SR. There had been growth of about 18 % in supply of coal in this
financial year. Capacity constraints were being faced at the rail head as well as
Paradip port. Rs.124 Crore investment had been planned by MCL for doubling
line in the Talcher coal fields and for automatic signaling etc between Talcher and
Paradip. Track doubling was required in the Talcher-Rajatgarh sector while
automatic signaling required in the Khurda-Duvvada & Duvvada-Vijayawada
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 60
sections. The question of investment in these areas needed to be sorted out,
since Railways was reluctant to do so. Additional Track Hopper was also required
at Paradip Port. MCL was willing to increase dispatch to the extent possible and
issues could be sorted out bilaterally with MCL. He pointed out that the
production in MCL was expected to go up to 160 MT in 2016-17 from the present
level of 108 MT. With higher production, the constraints in dispatch were to be
addressed. Capacity building was highly essential in this regard.
18.4 MS I/c, SRPC stated that issues such as reduction of unloading time/detention
time, coal held up Paradip Port, signing of new FSA, Washery issues etc were also
needed to be addressed.
18.5 MD, APGENCO thanked MCL for meeting APGENCO’s requirement during past
one year and expressed hope that such support would continue. He also thanked
SRPC for organizing the meeting with MCL and Railways. He said one basic issue
was the congestion between Talcher-Vijayawada. This was a heavy density track
and loading was already around 130%. In the meeting with Railways, need was
being expressed for an additional line. He suggested that MCL may kindly take
the lead and convene a Meeting with the state utilities and Railways so that a
long term solution could be evolved. APGENCO was helping to some extent with
regard to automatic signaling upto Vijayawada. However on account of track
congestion, RSR mode was becoming inevitable, though the cost involved was
more. This additional cost was getting passed on to the end consumers ultimately.
18.6 Chairman, TANTRANSCO said that till end September, TN was getting excellent
support from MCL with supply being around 7 Rakes/day. However, the supply
had now fallen to only around 3-4 Rakes/day. He informed that three additional
600 MW thermal units in the state were running and getting added to the grid.
He requested for better dispatch in the coming months, especially considering the
additional requirement of the new 600 MW units. Import of coal would not fully
address the problem since blending could be done to a limited extent. He said
that supply to central sector projects at Ramagundam, Talcher –II & Simhadri also
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 61
needed to be improved. He suggested for assistance from the Singareni mines in
AP under such circumstances.
18.7 Director, MCL suggested that NTPC and State Gencos could take up the issues
with Railways in a joint meeting. He stated that coal supply to TN had been
affected due to recent cyclone in Orissa & AP. At many locations, the railway
tracks had been washed away. However, he assured that the supply situation
would improve in the coming days.
18.8 Chairperson SRPC & CMD APTRANSCO opined that the issue may need to be
highlighted to Railways since it was their primary responsibility to ensure that
goods are transported to the destination through adequate augmentation. In
case Track congestion issues were addressed, it would ensure higher revenues
not only for MCL and Railways but would also help reduce the additional financial
burden on Gencos. The generation levels in the thermal stations would also
improve. He suggested that the issue could be taken up with Railways through
MoP. He stated that Singareni being an open cast mine gets flooded during heavy
rains. There were some quality related issues, but by and large the supplies could
be maintained.
18.9 ED, SRLDC observed that the constraints in coal supply were noted. Since it
appeared that in the short term, there were no ready solutions to address the
coal shortage issue, appropriate Load Generation balance would need to be
maintained by the constituents through load shedding. In view of the prevailing
coal shortage situation, he requested NTPC Talcher & MCL to coordinate
regarding likely coal receipts. This would help in accurate declarations in advance
so as to ensure that spare corridor is released for STOA transactions. This would
help minimize the power shortages in the region to that extent.
18.10 After deliberations, it was agreed that the matter would be taken up with Railway
Board/Ministry of Railways through MoP highlighting the constraints in coal
supply being faced by SR on account of track congestion etc.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 62
18.11 Distribution of Coal Stock at Talcher STPS
18.11.1 Honb’le CERC in its Order dated 23.07.2013 (Para 19) in respect of Petition
No.152/MP/2012 relating to blending of imported coal and other incidental
issues had observed the following:
“The petitioner has alleged that NTPC is maintaining common coal
stock for Talcher STPS Stage-I and Stage II, though separate coal
linkages have been allocated to them. The petitioner has sought
direction to NTPC to maintain separate coal stock on the ground that
the beneficiaries of Talcher STPS Stage-I and Talcher STPS Stage-II are
from different regions. It appears that the question was raised at the
ERPC forum. The ERPC had constituted a Committee with Director-
level executive of the petitioner as one of the members of the
Committee which decided that the coal stock at Talcher STPS should
be distributed between Stage I and Stage II in the ratio of 1:2. The
representative of the petitioner does not appear to have expressed any
dissent or reservation as the decision of the Committee is unanimous
as noticed from the minutes placed on record by NTPC. In view of the
decision in ERPC forum, any direction for maintenance of separate coal
stock for Talcher STPS Stage I and Stage II becomes irrelevant because
the coal is to be used in the agreed proportion.”
18.11.2 In the 86th
Meeting of OCC held on 13th
August 2013, SRLDC had brought this
issue to kind notice. In the 87th
Meeting of OCC held on 11th
September 2013,
SRLDC had informed that at times, the DC between Stages I & II was not being
carried out in the ratio of 1:2. NTPC had informed that DC could only be
monitored on a monthly basis, since it was difficult to maintain 1:2 ratio on
block or day to day basis on account of number of technical / infrastructural
issues.
18.11.3 In the Meeting, MS I/c, SRPC informed that this issue had been deliberated in
the TCC Meeting and the following had been noted:
� SRPC had pointed out that the cumulative availability during the
period April – September 2013 for Talcher STPS-I & Talcher STPS-II
were around 85% & 75% respectively. Higher DC during monsoon
(when surrenders are more), peak hour DC being lesser than DC
during other hours etc also needed attention. KPTCL had said that
beneficiaries of Stage-II being located in an energy deficit region
should not face loss of availability as compared to Stage I
beneficiaries.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 63
� NTPC had informed that the ratio between Stage-I & Stage-II was
1.95 (2008-09), 2.15 (2009-10), 2.12 (2010-11), 2.19 (2011-12), 2.02
(2012-13) & 1.8 (2013-14). Ratio of the DCs should be monitored on
a long term basis and certainly not on a day to day basis or block to
block basis. It was evident from the above that for the last four
years, SR constituents had been offered more power.
� SRLDC had pointed out that during coal shortage conditions, it was
observed that DC for Talcher Stage-II was relatively lower compared
to that of Talcher Stage-I.
� After deliberations, NTPC had been suggested to distribute the coal
in 1:2 ratio and accordingly carry out DC declaration. It would also
be ensured that during coal shortage conditions, and with all units of
Stage I & II being available, the DC declaration would be in 1:2 ratio.
18.11.4 Regional ED, NTPC said that on a yearly basis, the DC of Talcher-II had been
relatively higher during the past couple of years. During coal shortage
conditions also, DC of Stage-I & II would be given in an equitable manner.
However as stated earlier, it would not be possible to ensure the 1:2 ratio on a
day to day basis, on account of planned/forced outages of units etc.
19. ITEMS AGREED IN 36TH STANDING COMMITTEE MEETING & 16TH MEETING OF SR
CONSTITUENTS REGARDING LTA AND CONNECTIVITY APPLICATIONS
19.1 The 36th
Meeting of Standing Committee on PSP of SR as well as the 16th
Meeting
of LTA and Connectivity were held on 4th
September 2013 (Minutes attached as
Annexure-XXIV).
19.2 In the Meeting, MS I/c, SRPC informed that TCC had recommended the schemes
for approval of SRPC.
19.3 SRPC approved the schemes finalized in the36th
Meeting of Standing Committee.
20. IEGC RELATED ISSUES
20.1 Restricted Governor Mode of Operation (RGMO)/FGMO of Generating Units &
MVAR Interchange
20.1.1 In the 22nd
Meeting of SRPC, the following had been noted:
� SRLDC had expressed concern over low RGMO response due to
which, frequency was going as high as 50.8 Hz during long
changeover period. SRLDC was finding it difficult to maintain
integrity of system, since lines were also tripping on over voltage. It
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 64
was difficult to bring back the lines after trippings. The margin was
also getting affected. RGMO/FGMO response was being discussed in
every OCC Meeting. Concrete action was required to be taken so
that adequate response is visible in Control Room. State generators
would have to reconcile the response being obtained at generators
with reference to response being observed in SLDC.
� Regulatory requirement was required to be met. Any exemption
required in this regard needed to be obtained from Hon’ble CERC.
Validation of the data observed at station and at SLDC/SRLDC should
be taken up regularly to reduce mismatch of data.
20.1.2 Three meetings regarding the status of implementation of RGMO/FGMO and
performance of units as well as MVAR interchange of generating units were
conducted on 29th
June 2013, 25th
July 2013 & 30th
September 2013. Further,
the issue was also discussed in the Special Meeting of TCC held on 21st
August
2013. The following had been noted in the Meetings:
� Generators had agreed to put all the machines on continuous basis
as per the declaration on RGMO / FGMO with Manual Intervention
(MI) within one week.
� Necessary action would be ensured to avoid any switching off / on
by the unit operators as per their discretion.
� Performance Status would be monitored at senior level and efforts
would be taken to overcome the shortfalls and ensure maximum
possible contribution through RGMO / FGMO with MI.
� SLDCs would also monitor the RGMO / FGMO with MI performance
of the generating units in their control area.
� SRLDC / SRPC Secretariat pointed out with concern that primary
response was necessary for secure grid operation. Generators
needed to ensure the primary response which was also a Regulatory
requirement. In event of inadequate response, since grid security is
at stake, SRLDC / SRPC may be constrained to take up this issue at
appropriate forum.
� Feedback, if any, on the draft of Reactive Power Demonstration
Procedure could be furnished by 7th
September 2013. The
demonstration schedules could be finalized in the next OCC Meeting.
The nodal officers to furnish the MVAR interchange details to the
web group in a timely manner.
Subsequently the Reactive Power Demonstration Procedure was
finalized by SRLDC.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 65
20.1.3 Regarding MVAR Interchange, the following had been noted in the meeting on
25th
July 2013 and also noted in the Special TCC on 21st
August 2013:
� All stations to ensure their GT Tap positions are optimized so as to
bring Grid Voltages to Nominal values.
� Respective SLDCs would monitor VAR Interchange of the generators
under their control and ensure better voltage profile.
� SRLDC could issue messages for Violation of IEGC clause 6.6.6
“The ISGS and other generating stations connected to regional
grid generate/absorb reactive power as per instructions of RLDC,
within capability limits of the respective generating units, that is
without sacrificing on the active generation required at that
time. No payments shall be made to the generating companies
for such VAR generation/absorption.”
‘Regional Grid’ means the entire synchronously connected
electric power network of the concerned Region’
� Demonstration of MVAR capability to be conducted – WR has
already carried out the exercise.
� Under Exciter Limiter (UEL) & Over Exciter Limiter (OEL) to be set
w.r.t. Capability Curves.
� AVR should be kept on Constant Voltage Mode and not on Constant
Power Factor, Constant MVAR Mode or any other mode (manual).
� All the units connected to same bus to have their taps at same
voltage level.
� Units to perform as per Capability Curve – at lower generation levels
more absorption/injection possible.
� Tap positions to be optimized from 01.08.2013 to 31.08.2013. Dates
of Tap changes and set tap positions should be communicated to
SRPC/SRLDC as and when changes are carried out. The same should
also be reflected in the information which would be furnished for
future analysis.
20.1.4 In the Meeting, MS I/c, SRPC informed that in the TCC meeting, the following
had been noted:
� SRLDC had expressed concern over the fact that the actual response
observed was only about 15% - 20% of the expected response. The
response was mostly from hydro units and from thermal units in an
inconsistent manner. About 30,000 MW out of 40,000 MW
capacity in the region had been declared to be RGMO/FGMO
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 66
compliant. About 5 % of this was expected to be available any time
for system contingencies. At times, even negative response was
witnessed. A Special Web Group had also been created for this
purpose. In the Special Meetings, the generators had agreed that
the data and the analysis portion were in order. Toggling, technical
minimum, water spillage, fuel quality etc. were some of the issues
which were being reported by the generators for non-performance.
SRLDC also added that in case there was any delay was anticipated
in RGMO implementation, adequate response should be ensured
through operator intervention. For this purpose, the alertness and
promptitude of the unit operators was highly essential. They also
stated that SRLDC may be constrained to approach Hon’ble CERC on
this matter.
� APGENCO had informed that with regard to its units, Hon’ble CERC
had passed an Order dated 29th
April 2013. Administrative approval
for `67 Crores had been accorded by the Board for completion of
the works identified but the installation works were likely to be
completed between 2014-16. There were a number of old units
available and hence the works were consuming more time.
� KPCL had informed that the GT Taps at Kadra & Kodasalli had been
changed as per the recommendations finalized in the Special
Meeting on RGMO/MVAR.
� MS I/c, SRPC had said that it was a matter of great concern that
despite conducting a number of Meetings, the response had not
shown much improvement. Adequate RGMO response was one of
the pre-requisites for NEW-SR Grid synchronization scheduled in
the first quarter of 2014. He also added that MVAR capability
demonstration procedure had been finalized in consultation with
the generators. In the OCC Meeting, NTPC had enquired whether
the demonstration was stipulated in IEGC Regulations. It was
clarified that demonstration was not stipulated IEGC Regulations. It
had however been observed during deliberations in the MVAR
Interchange Meetings that machines in some of the stations were
not performing as per capability limits. He pointed out that similar
exercise had been carried out in Western Region & Eastern Region.
� After deliberations, all generators had agreed to carry out MVAR
Capability Demonstration as per the finalized procedure. The
schedule for this purpose would be finalized shortly.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 67
20.1.5 In the Meeting, MS I/c, SRPC stated that such low level of response was a
matter of concern. Though detailed unit-wise analysis had being carried out
in a number of Meetings, not much perceptible improvement had been
observed.
20.1.6 ED, SRLDC said that generators were citing problems such as wet coal, valve
wide open etc for the poor response. However, cushion had to be provided
for RGMO and hence DC declaration was required to be made accordingly.
Due to the poor response, system was being deprived of a self-healing
mechanism. It would be difficult to maintain the grid integrity, if such level of
inadequate response continues.
20.1.7 Chairperson, SRPC & CMD, APTRANSCO stated that generators may be facing
issues in maintaining reserves in the present power deficit scenario. He also
suggested it could be explored whether the relief could be provided on the
load side.
20.1.8 MD, APGENCO pointed out that the GCV of coal receipts varies widely from
time to time. Hence through appropriate blending etc, the GCV of coal would
need to be maintained which was a challenge by itself.
20.1.9 ED, SRLDC pointed out that in many cases the RGMO performs and give relief.
But as per assessment, during any wet coal or poor coal quality conditions etc,
adequate margins may need to be maintained while declaring. Frequency
excursions during load changeover were mainly on account of non-response
by the machines in RGMO. Three Meetings had taken place in this regard, and
adequate response was highly essential to ensure that grid security was not
threatened. Sudden changes in load were also happening. The matter was
being constantly taken up with the States and also under clause 1.5 of IEGC. In
case load transitions were smoother, the requirement of RGMO response
would get reduced to that extent.
20.1.10 Chairperson, SRPC suggested that feedback in this regard could be further
analyzed. Generators could adopt measures to the extent possible, while load
management could also be improved in the interest of grid security.
Minutes of 23rd Meeting of SRPC held on 26th October 2013 Page 68
20.2 Arranging of interruptible loads in four groups
� In the OCC meetings, it was noted that as per IEGC, to maintain the
frequency within stipulated band and also to ensure network security,
the interruptible loads were to be arranged in four groups of loads.
This was for the purpose of scheduled power cuts/load shedding,
loads for unscheduled load shedding, loads to be shed through UF
relays, df/dt relays and loads to be shed under any SPS Scheme. These
loads were to be grouped in such a manner that there was no
overlapping between different groups of loads.
� SRLDC & SRPC Secretariat had pointed out that the scheme was not
meeting the Regulatory requirement fully and further action was
required in this regard.
20.3 Automatic Demand Management Schemes
� Automatic Demand Management Scheme in line with clause 5.4.2 (d)
of the IEGC was to be provided by all the constituents by 1st
January
2011.
� SRLDC & SRPC Secretariat had pointed out that automated scheme
was to be in place to meet the Regulatory requirement.
20.4 Automatic Load Disconnection Schemes for overdrawing constituents
In the 14th
meeting of SRPC held on 27th
August 2010, it was agreed to implement
Automatic Load Disconnection Scheme for overdrawing constituents with the
following relief:
Sl. No. Constituents Load Relief
1 APTRANSCO 450 MW
2 KPTCL 350 MW
3 KSEB 125 MW
4 TANTRANSCO 650 MW
5 Puducherry 25 MW
� It was noted that the Automatic Load Disconnection Scheme was
part of Automatic Demand Management Scheme.
� States had been requested to ensure adequate load relief in the
interest of grid security.
� SRLDC & SRPC Secretariat had pointed out that automated scheme
was to be in place to meet the Regulatory requirement.
20.5 Sudden Change in Drawal/Frequency Excursion
20.5.1 States had been requested to adhere to drawal schedule and also not to under
draw during high frequency conditions.
