Agenda for 22nd WRPC meeting to be held at Gandhinagar on 26.02.2013 2
ITEM NO. 3: OTHER RECOMMENDATIONS (OF ZALTE COMMITTEE)
A. Defense Mechanism for high frequency
After detailed studies by WRLDC following units were identified for automatic tripping
at high frequency (51.5 Hz) to help arresting the rise of frequency in case of
islanding of WR from rest of NEW grid :
1. KSTPS-7 (500 MW) 2.VSTPS-7 ( 500 MW) 3. CGPL-10 (830 MW)
During the TCC meeting held on 8.11.2012, Member Secretary I/c WRPC had
informed that in the PCM meeting held in 7th September 2012 in Pune, different
utilities are adopting different high frequency trip settings with different time delays
and there was not surety of tripping of these units of generators. He had informed
that the intention of the Zalte committee was to identify three units, checked by
simulation studies, which would definitely trip at 51.5 Hz. During the 21st WRPC
meeting, ED(Commercial), NTPC WR intimated that the matter regarding tripping of
NTPC units Korba-7 and VSTPS-7 was discussed by the NTPC Corporate and in the
opinion of NTPC high frequency situation does not warrant a tripping of the unit. He
informed that the machine will be fully unloaded by governor action and if further
discussions are required the same can be discussed in the 29th November 2012
meeting.
In the meeting held on 29.11.2012, NTPC expressed concern that in the grid of
40,000 MW, identification of units should be done equitably. Only NTPC units should
not be singled out for the said issue.
NTPC representative made following points:
i. Rise in frequency is not a situation which warrants drastic action to trip units
to reduce generation, as it cannot cause a collapse of the power system,
unlike the situation of low frequency. High frequency can be easily controlled
by controlling the generation. From the system point of view higher than
nominal frequency is not considered dangerous/harmful to the system and
system equipments.
ii. At frequency varying from 51.0-51.5Hz, all thermal machines in the system
(except the older mechanically governed machines), including CCGT units will
start unloading as per the droop characteristics. Assuming a governor droop
Agenda for 22nd WRPC meeting to be held at Gandhinagar on 26.02.2013 3
of 5%, this would result in reduction of 20% of the generation capacity in
service, for a frequency rise of 0.5Hz, above this threshold. This unloading
feature can neither be offset beyond 51.5Hz nor can it be prevented, being a
safety feature.
iii. CCGT units at Jhanor start unloading at 51.2Hz and are wired to trip at
51.7Hz. Kawas CCGT units start unloading at 51.2Hz as per its governor
droop.
iv. In the event of such a frequency rise it is likely that some generators trip
during the re-adjustment of their process, inadvertently. During the said
disturbance also such tripping had taken place. If the total generation
available after such intended and inadvertent unit outages fall short of the
load, the system will be facing a far more disastrous frequency decline
situation.
In reply, Member Secretary I/c, WRPC intimated that a quick and adequate response
in generation shedding is required under such disturbances. The tripping of above
units have been arrived by giving due considerations to the above facts and system
studies carried out by WRLDC. Also it may be noted that the above trippings have
been envisaged after resorting to all the measures required to be undertaken under
such circumstances by WRLDC in the real time grid management. Therefore NTPC
should not feel that the above units have been singled out.
In view of system security, NTPC may agree to the above recommendations of
WRPC and implement the tripping of above generators at high frequency of 51.5 Hz.
WRP Committee may like to discuss.
B. SPS of 400 kV Bina-Gwalior lines:
Following Units in WR were to be considered for backing down to the tune of 500
MW in the event of tripping of Agra-Gwalior lines and Bina-Gwalior lines :
B. ) Korba, Sipat, Vindhyachal STPS to control power flow towards ER
ii) CGPL & SSP* to control power flow in Zerda-Bhinmal-Kankroli lines
iii) JP Bina to control power flow in Bina-Mehgaon-Gwalior lines &
iv) ISP* to control power flow in Badod-Kota-Modak lines
Agenda for 22nd WRPC meeting to be held at Gandhinagar on 26.02.2013 4
*Since SSP and ISP are hydro units and may not be always available, Committee
recommended backing down of 500 MW at Korba, Sipat, Vindhyachal, CGPL and JP
Bina.
During TCC meeting held on 8.11.2012 GM, NTPC stated that NTPC units are
participating in RGMO. He stated that CERC norms require generation backing down
from short term, then medium term and long term units. These units are not
transacting with any utility in NR. Hence backing down of generation on SPS is not
required.
Member Secretary I/c WRPC stated that in case of 400 kV Agra-Gwalior tripping, a
SPS is under implementation under which NR system trips loads and WR system
has to back down generation. Hence this backing down is required and also the total
quantum is only 500 MW which is small as compared to grid size. Since this is a
protection scheme, the same may be agreed to in the interest of grid security.
Chairperson, WRPC stated that this SPS is required when there is an extreme
emergency and not normal Scheduling and withdrawal of units. He stated that if
NTPC wishes to go through the simulation study they are welcomed to coordinate
with WRLDC. But since WRLDC has done the study and identified the units
accordingly, for the WR system interest NTPC need to accept the same. WRPC
recommended as above
However NTPC continued their reservation and requested for further deliberation in
a meeting on 29th November 2012 wherein NTPC representative stated that none of
the stations named in the SPS action list have any transaction to NR and hence
consumption from these stations is within Western region only. Hence an SPS is
being planned for the said lines, the same should not involve the NTPC stations
mentioned. The stations with inter-regional transactions on the said line may be
considered under the SPS action list. In identification of the generating units to
control flow to ER, a cue may be taken from CERC Long Term, Medium Term Open
Access Regulations, 2009 which provide curtailment of power scheduled to short
term customer first followed by medium term customers and long term customers for
the reason of transmission constraint or in the interest of grid security. Therefore to
control flow towards ER the generating stations availing interregional links to export
power beyond WR should be identified and put under SPS.
Agenda for 22nd WRPC meeting to be held at Gandhinagar on 26.02.2013 5
During discussions it was felt that, the above arguments are valid during the steady
state conditions. Also the scheduling is done based on the assessment of availability
of transmission corridors by considering designed contingencies stipulated in IEGC.
However in real time, as seen during the GDs, there is hardly any time for manual
intervention for taking corrective actions. The actions suggested above by NTPC
may require considerable time. Further the electrical flows follow law of physics and
curtailment of schedules may not be a solution for maintaining the system stable
under tripping of these lines, since this may lead to rush of power in the other
corridors and may lead to unnecessary tripping other elements in WR system.
MS, WRPC stated that the above units have been identified based on the sensitivity
analysis carried out by WRLDC and these studies showed that the power flow in
Bina – Gwalior- Agra corridor is more sensitive to the above units. Generation control
at these units would control power inrush on other corridors after tripping of the line.
The total quantum of backing down from all the above units envisaged in the SPS is
only 500MW, as such NTPC shall not insist on excluding their units from SPS.
Therefore the SPS for backing down of generating units, in the event of tripping of
Agra-Gwalior lines would have to be implemented, for the security of the grid.
However NTPC retained their stand and did not agree for participating in back down
of generator as envisaged in SPS of Gwalior-Agra/Bina-Gwalior lines. MS WRPC
stated that non participation of NTPC would be again put up to WRPC.
In view of contingency of Bina Gwalior-Agra tripping apart from action envisaged by
NR, a deliberate effort fro WR is also of paramount importance to save WR.
Committee may deliberate further and advise NTPC to participate in defense
mechanism scheme being major player in the grid.
WRP Committee may like to discuss.
ITEM NO 4: IMPLEMENTATION OF DEMAND MANAGEMENT(IEGC 5.4), GRID SECURITY EXPERT SYSTEM AND DEMEND ESTIMATION: (A)Demand Disconnection
Clause 5.4.2 (d) of Grid code provides for formulation and implementation of
state-of-the art demand management schemes for automatic demand management
Agenda for 22nd WRPC meeting to be held at Gandhinagar on 26.02.2013 6
like rotational load shedding, demand response(which may include lower tariff for
interruptible loads) etc. by each SLDC through respective State Electricity
Boards/Distribution Licensees before 01.01.2011 to reduce overdrawal from the grid
to maintain the grid at the frequency in IEGC band. In this regard all SLDCs/STUs
may provide following requirements.
a) The current status of contingency procedures and arrangements
required to enable demand disconnection as mandated under Regulation
5.4.2(c)of Grid code
b) Automatic demand management schemes mandated under Regulation
5.4.2(d) of the Grid code indicating date of implementation, the
maintenance and operational preparedness of the scheme.
c) The contingency procedures to restrict the drawal of its control area
whenever the system frequency falls to 49.8 Hz(5.4.2a) and the requisite
load shedding scheme to avoid overdrawal at low frequency i.e <49.7 or
below(5.4.2b).
B. Load Curtailment Planning
Clause 5.4.2 (e) of IEGC stipulates that “In order to maintain the frequency within
the stipulated band and maintaining the network security, the interruptible loads shall
be arranged in four groups of loads, for scheduled power cuts/load shedding, loads
for unscheduled load shedding, loads to be shed through under frequency relays/
df/dt relays and loads to be shed under any system protection schemes identified at
the RPC level. These loads shall be grouped in such a manner, that there is no
overlapping between different Groups of loads. In case of certain contingencies
and/or threat to system security, the RLDC may direct any SLDC/SEB/Distribution
licensee or bulk consumer connected to the ISTS to decrease drawl of its control
area by a certain quantum. Such directions shall immediately acted upon. SLDC
shall send compliance report immediately after compliance of these directions to
RLDC.”
Agenda for 22nd WRPC meeting to be held at Gandhinagar on 26.02.2013 7
C. Demand Estimation for Operational Purposes IEGC clause 5.3
Quote
(e) “demand estimation for operational purposes is to be done on a
daily/weekly/monthly basis initially, mechanisms and facilities at SLDCs shall be
created at the earliest but not later than 1.1.2011 to facilitate on-line estimation
of demand for daily operational use for each 15 minutes block.
(f) The monthly estimated demand by the SLDC shall be provided to RLDC and
RPC for better operation planning
(h) In order to facilitate estimation of Total Transfer Capability /Available
Transfer Capability on three month ahead basis , the SLDC shall furnish
estimated demand and availability data to RLDCs
Unquote
D. Grid Security Expert System (GSES)
Subsequent to the Grid Disturbance on 30th & 31st July 2012, in a meeting held
between Union Power Minister of India with Chief Ministers / Power Ministers of
States of Northern Region on 06th August 2012, a 12 point resolution was drawn to
ensure that such type of incidents do not occur in future. Point No.11 pertaining to
defense plans stipulated that “POSOCO would evolve a contingency load shedding
protocol, especially when non frequency related load shedding is required.”
Based on the template prepared by POSOCO for ten number of scenarios
when the power system would be under stress, POWERGRID has planned an
automated defense plan for all five regions named as Grid Security Expert System
(GSES).
POSOCO vide letter No. POSOCO/NLDC date 11th Sept’12 has submitted
a detailed plan on ‘Automated defense plans for the All India electricity grids’ to CEA,
CTU, RPCs and CERC and requested that a discussion on the same may be
Agenda for 22nd WRPC meeting to be held at Gandhinagar on 26.02.2013 8
facilitated at the RPC level so that state-wise details are frozen and any other state
specific scheme that may be required could also be finalized.
However, in a meeting taken by Additional Secretary, Minister of Power
on 12th January 2013 in NR , it has been decided that GSES be discussed in the
ensuing meetings at RPC level. Further order date. 14.1.13 issued by CERC on the
hearing held on 8th Jan’13, in petition No.264/MP/2012, had also directed for
discussion of the schemes at RPC forum and the recommendations of the RPCs be
placed before the Commission for consideration and necessary directions. As per
clause 10 of the above order,
Quote
Accordingly, we direct that the Regional Power Committees of all regions
shall discuss the issue of “implementation of the Automatic Demand Management
Scheme at the SLDC/distribution company level” as an agenda item within one
month from the date of issue of this order and file their decisions on affidavit within
one week thereafter after serving the copies thereof on all the constituents of the
respective RPC. Since the Automatic Demand Management Scheme is required to
be implemented by SLDCs through their respective State Electricity
Board/Distribution Licensees in accordance with Regulation 5.4.2(d) of the Grid
Code, we direct that all Distribution Licensees would also participate in the
respective RPC meetings and their views should be taken into consideration.
We further direct the SLDCs to provide all necessary data and assistance
to NLDC and respective RLDCs for effective implementation of the Automatic
Demand Management Scheme.

In the recently held 116th Protection Committee Meeting on 30th & 31st
January 2013, WRLDC requested for inclusion of agenda point about Grid Security
Expert System (GSES) based on the template prepared by POSOCO for ten number
of scenarios when the power system would be under stress. In the meeting, WRLDC
gave a presentation about the ten number of scenarios which requires automatic
action for safe system operation and about the common logic for operation of the
scheme. It was explained by WRLDC that out of the ten scenarios , 9 are for
Agenda for 22nd WRPC meeting to be held at Gandhinagar on 26.02.2013 9
Demand/load disconnection schemes and the same can be implemented with the
help of SLDCs and DISCOMs for complying Regulation 5.4.2(d) of Grid Code.
It was earlier decided in the 443rd OCCM that preliminary discussion would
be held in 116th PCM on 30th and 31st January, 2013 at Nagpur and then in next
OCC and outcome would be placed in next WRPC meeting to be held on 25th and
26th February, 2013.
Report prepared by POSOCO is available on the link
www.wrldc.com/downloads/documents/GSES pdf.
This issue have already been discussed at 24th TCC & 27th NRPC meetings held on
29/30th November 2012 respectively. Discussion in the GSES held in NRPC Meeting
and CSPTCL comments on the subject are enclosed at Annexure- 4. The committee may discuss GSES in detail and arrive at common philosophy so that further modalities for implementation could be discussed further. ITEM No. 5: PERFORMANCE OF WR GRID DURING OCTOBER 2012 TO
JANUARY 2013 5.1 SYSTEM PERFORMANCE Frequency: During months of October, November, December 2012 & January 2013, the grid
operated in the IEGC frequency range of 49.7 Hz to 50.2 Hz for 90.39 %, 85.83 %,
84.10 % and 80.95 % of time respectively. The frequencies below 49.7 Hz were from
1.79 % to 4.63 % of time during October 2012 to January 2013. In higher frequency
regime, system frequency remained above 50.20 Hz for 6.28 %, 12.38 %, 11.51 %
and 14.42 % of time respectively in October, November, December 2012 & January
2013. The monthly average frequency was 49.98 Hz in October 2012, 50.02 Hz in
November 2012, 50.00 Hz in December 2012 and 50.01 Hz in January 2013.

WRPC Committee may like to note. ITEM No 7: ANNUAL LOAD GENERATION BALANCE FOR THE YEAR 2013-14
A meeting of LGBR group was held on 29th November, 2012 at WRLDC, Mumbai. The
group finalized the tentative outage Program of major thermal units for the Year 2013-
14. The same was sent to CEA for finalizing annual generating target for the Year
2013-14 & uploaded at WRPC website.
Agenda for 22nd WRPC meeting to be held at Gandhinagar on 26.02.2013 13
A meeting for finalizing the generation target in respect of various generating units
including IPPs for the year 2013-14 was organized by CEA on 28.01.2013. It was
requested that IPPs expected to commence delivering of power in WR grid during year
2013-14 may furnish month wise generation for intimation to CEA for further needful.
Regarding the Annual LGBR for 2013-14 based on data received so far WRPC,
preparation of draft Annual LGBR is under progress.
WRPC Committee may like to note. ITEM NO 8: UP-GRADATION OF BINA-GWALIOR-AGRA LINK TO 765 KV OPERATIONS: The OCC Sub-Committee discussed the up-gradation work of 765 kV Bina-Gwalior-
Agra link. With the present level of power transfer at 765 kV level to NR, they
apprehended a very high voltage situation particularly in Seoni, Bina, Gwalior areas.
Already many lines are kept open to curtail high voltage. There seems to be no
significant increase in generation levels and therefore charging at 765 kV level will
increase the voltages further. Accordingly the sub-committee requested
POWERGRID to carry out necessary studies, in line with the present generation and
anticipated generation and off-peak scenario in WR and chalk out the reactive power
absorption requirements so that up-gradation to 765 kV operation of the above lines
may eventually take place. The results of the studies may be discussed in the OCC/
Study forum of WR before operation at 765 kV levels commence.
WRPC may like to discuss.
ITEM NO 9: DECISIONS ON IMPORTANT ITEMS FROM 35TH SCM HELD ON 03/01/2013 AT GURGAON: Following are the decisions taken in the above SCM. For details kindly refer to the MOM.

Agenda for 22nd WRPC meeting to be held at Gandhinagar on 26.02.2013 14
2) Since a substantial quantum of DD and DNH was being catered through
GETCO system and resulting in the critical loading of 220/66 kV ICTs at
Bhilad and Vapi GETCOI s/s, it was decided that after the commissioning of
3rd ICT at Vapi(PG), in case critical loading of GETCO system is not relieved,
a meeting of the stakeholders would be convened to review the 66 kV
interconnections between GETCO system and DD & DNH systems.
3) Due to ROW constraints in DD/DNH system, the earlier agreed arrangement
was modified as follows:
(i) 220 kV Kala – Khadoli D/c
(ii) 220 kV Kala – New Kharadpada switching s/s D/c
(iii) 220 kV New Kharadpada switching s/s – Kharadpada D/c
B. Reactor at 400 kV Bina s/s It was decided to replace the 63 MVAR Bus Reactor at Bina(PG) by 125
MVAR Bus Reactor and keep 63 MVAR Bus Reactor as regional spare.
C. Increase in provision of PMUs under URTDSM In order to encourage vendors to set up manufacturing and O&M support
facilities for PMUs in India, the provision for indigenous PMUs under
URTDSM was raised to 30% from 15%
D. Proposal for Static VAR Compensator (SVC) in WR In line with the Recommendations of Enquiry Committee of Grid disturbances
in NEW grid in July 2012, regarding installation of adequate static and
dynamic reactive power compensators , the SCM, on basis of system studies,
has decided to install in the first phase SVC’s at following place in WR
1) Gwalior +/- 400 MVAR
2) Sholapur(PG) +/- 400 MVAR
3) Aurangabad(PG) +/- 400 MVAR
4) Satna +/- 400 MVAR
E. Termination of Vapi-Navi Mumbai 400 kV D/c line at Kudus s/s (MSETCL) 1) Due to severe ROW problems, forest, wildlife and eco-sensitive zones
clearances pending, the 35th SCM decided that the 400 kV Vapi-Navi
Mumbai line shall be terminated at Kudus s/s near Padghe. However
Agenda for 22nd WRPC meeting to be held at Gandhinagar on 26.02.2013 15

accounting. The existing software’s for UI and REA were developed using earlier
Visual Studio Platforms procured about 10 years back. The complexity of accounting
has increased over the time with Inter-Regional transactions, frequent revisions are
necessary. Further new regulations for RTA, RTDA, RRF etc., are coming in place.
For RTA and RTDA software is developed from local vendor and has a small AMC
component. Other software’s have to be shifted to newer platforms of Visual Studio
2012. Since the bills of the utilities have huge financial implication, so prompt and
error free accounting is the need of the present. The manpower at WRPC is limited
and so technological software solution in the form of getting some software’s
developed / maintained from local vendors is required. Some in-house development
is also envisaged. It is necessary to procure Visual Studio 2012 for the same.
In view of the above, following proposals are made 1) Renewal of existing AMC for software maintenance for RTA and RTDA
2) Procurement of Visual Studio 12
3) Software help for revision of REA/UI for previous cases
The expenses for the above can be met within the existing contingency fund and
would be of the order of Rs 3 lakhs.
WRPC may like to approve ITEM NO. 12: RENEWABLE REGULATORY FUNDS MECHANISM:

ITEM NO. 13: EVACUATION OF POWER FROM KORBA STPS-III OF NTPC. Back Ground : In the matter of evacuation of power from Korba unit 7 of stage III of NTPC
station after declaration of commercial operation (COD) of the unit till commissioning
Agenda for 22nd WRPC meeting to be held at Gandhinagar on 26.02.2013 19
of the identified 400 kV Raipur-Korba D/c line, Hon’ble CERC vide para no 32 of
order dated 6.9.2011 in petition no 122/2011 has directed as follows:
Quote:
“In view of the foregoing discussion, we have come to the conclusion that the
petitioner is bound by the terms and conditions of the BPTA and the Implementation
Agreement signed by it with the CTU. However, after allocation of power from
Korba-III by Government of India, Ministry of Power to the western region
beneficiaries and execution of PPAs by the petitioner, the western region
beneficiaries have become long term customers by operation of Regulation 2(1)(m)
of the Connectivity Regulations. The long term customers have right to schedule
power on long term access from Korba-III on the available spare capacity and such
scheduling shall have priority over the medium term open access and short term
open access. The ATS for Korba-III was declared under commercial operation with
effect from 27.6.2011. Consequently, scheduling of power from Korba-III for the
period from 21.3.2011 to 26.6.2011 on the existing transmission capacity shall be
deemed to have been made on long-term access. The energy and UI accounts shall
be revised and settled accordingly. “
Un-Quote
The WR Power Committee in the 18th WRPC meeting held on 1.10.2011 decided
that WRLDC would refund whatever charges collected by WRLDC from all the
constituents on account of short term scheduling of power from Korba-III and would
furnish necessary data to WRPC Secretariat to revise the energy and UI accounts
and suggested that accounting details may be finalized based on data to be
furnished by WRLDC in line with the above mentioned CERC order dated 6.9.2011.
In order to implement the above order of Hon’ble Commission, WRLDC have
submitted the 15-minute block-wise data viz DC of unit no 7 of Korba-III,
entitlements of beneficiaries of Korba-III, their Long-Term schedules from Korba-III
and related data necessary for preparation of revised energy and UI accounts data
on 08.02.2012. Accordingly, the REAs have been revised on 30.03.2012.
During examination of revision of UI based on the data submitted by WRLDC it
was observed that the revised schedules submitted by WRLDC remained
Agenda for 22nd WRPC meeting to be held at Gandhinagar on 26.02.2013 20
unchanged and there would not be any change in payable/receivables on account of
this for the above period. Hence the revision of UI A/c’s was not undertaken.
In the 61st CCM, while discussing examination of the revision of UI, beneficiaries
expressed that during few occasions they were unable to revise the schedules since
the schedules were treated as STOA and any revision of the requisitioned schedules
would not have been effective before expiry of a minimum period of two (2) days and
not from the fourth time block as in case of LT schedules. Conversion of STOA
schedules of beneficiaries to LTA schedules without any change in schedules due to
revision of DC (as available in LTA schedules) have deprived the beneficiaries to
avail the benefit of revision of schedules due to revision of DC which otherwise
would have been available had the schedules been treated as LT schedules.
The Commercial Committee suggested forming of a small group comprising of
members from constituents, NTPC & WRLDC who would look into such instances
and the practicability of implementing post-facto revision of schedules and give its
recommendation accordingly.
The group met on 14.05.2012, and it was decided that NTPC would submit
following data for the period 21.3.2011 to 30.6.2011 for revision of schedules:-
(i) date and time of tripping of Korba-III unit
(ii) declared date and time of restoration of the unit
(iii) actual date and time of restoration of the unit
(iv) DC prior (at the time of tripping)
(v) DC after restoration (at the time of restoration of the unit).
During the 20th WRPC meeting held at Indore on 18.05.2012, WRLDC and PGCIL
representatives informed that a petition has been filed with Hon’ble Appellate
Tribunal against the above order of Hon’ble CERC by PGCIL. MPPMC in the
meeting requested to issue the revised UI account in defined time frame preferably
before next WRP Committee meeting to be held in September 2012, which was
agreed by the WRP Committee.
WR Power Committee in 20th WRPC recommended that since there is no stay on
Hon’ble CERC order by Hon’ble Appellate Tribunal, the CERC directives could be
Agenda for 22nd WRPC meeting to be held at Gandhinagar on 26.02.2013 21
acted upon so that the dues are settled as per CERC order, revision of UI A/c’s shall
be carried out by WRPC on receipt of revised data from WRLDC.
As decided by small group comprising of members from constituents, NTPC &
WRLDC regarding submission of data by NTPC, NTPC vide email dated
01.06.2012 submitted the data which was circulated to the beneficiaries and
WRLDC for validation vide WRPC letter WRPC/Comml-I/3/ABTREA/2012/739

May 2012 at WRPC.
WRLDC vide letter WRLDC/MO-II/2012/6806 dated 13.08.2012 have intimated
that the Data forwarded in the above matter only contains tripping details of NTPC
Korba Stage-III and with this data, the schedules cannot be revised and 96 block
wise DC which is agreeable to all the constituents is required for revision in
schedules of NTPC Korba Stage-III. Further POWERGRID did not agree with the
aforesaid CERC order dated 06.09.11 and has submitted its appeal before Appellate
Tribunal against the CERC order. The same has been accepted by Appellate
Tribunal and the first hearing already taken place on 23.07.2012. Further they have
intimated that the matter is still sub-judice and the decision of Appellate Tribunal is
awaited, the matter will be settled after the decision of Appellate Tribunal.
WRPC in view of the decisions of 20th WR Power Committee, vide letter
WRPC/Comml-I/3/ABTREA/2012/1296 dated 17.08.2012, requested WRLDC to

ITEM No.14: SCHEDULING OF KAWAS AND GANDHAR: In the 63rd CCM NTPC representative stated that the technical constraints in running
the units at lower than technical requirement of machines was discussed and noted
in 442nd and 443rd OCC meetings. NTPC requested beneficiaries for scheduling of
Kawas and Gandhar at least up to technical minimum during night hours for on-bar
gas turbines in combined cycle mode taking into account their day’s total energy
requirement. NTPC also intimated that Kawas and Gandhar stations are getting
schedules less than technical minimum during night hours. Further, the less
schedules during Night hours results in the unintentional over injection by stations to
maintain the technical minimum generation level. Further, NTPC mentioned that, as
per the latest Govt. notification, the under-utilized portion of cheap domestic gas may
get diverted.
In the 63rd CCM constituents responded that they are not in a position to adhere to
technical minimum schedule during night hours in view of strict adherence to merit
orders and injections due to must buy provision for purchase from renewable
sources (specifically wind energy in case of GUVNL) etc. Beneficiaries also
mentioned that although they are conscious of the fact that under-utilization of cheap
domestic gas allocated for Kawas and Gandhar may lead to its diversion, they are
not in a position to schedule this power in view of reasons noted above.

ITEM No.16 : SCHEDULING ISSUES AT NTPC STATIONS DURING FUEL SHORTAGE CONDITIONS: GUVNL vide letter No. GUVNL:GM(Com.):209 dated 31.01.2013 (copy enclosed at
Annex-16.1) have intimated that the entitlement of GUVNL in respect of NTPC
generating stations namely Vindhyachal-1,2,3, and Sipat-1,2 as per the data of
WRLDC web site for the month of Sep 12 to Nov 12 is not matching with the
entitlements / availability certification in the monthly REAs issued by WRPC. Further,
the scheduled energy of GUVNL in respect of NTPC generating stations is
substantially less than entitlement/ availability certification of GUVNL certified in
REAs. It is learnt that in case of NTPC generating station the availability of the
station has been considered on the basis of maximum availability / generation during
peak hour of that day applied for full day, even though the plant availability for
generation during off peak hours was less due to fuel shortage.
The matter was deliberated in the 63rd CCM and following observations were made
MSEDCL representative stated that they have taken up the issue with NPC vide
letter No. CE/PP/NTPC/33820 dated 06.12.2012 (copy enclosed at Annex.-16.2),
wherein the applicable provisions i.e. Chapter-3, clause-21 (4) of the CERC Terms
and Condition of Tariff Regulations, 2009 was cited. As per this provision, it is
mandatory for the generating company to obtain consent/clearance of the
beneficiaries of the power station before making any change in the operating pattern
Agenda for 22nd WRPC meeting to be held at Gandhinagar on 26.02.2013 27
in case of fuel shortage. However the consent was not obtained from MSEDCL.
During the fuel shortage period the scheduling is required to be optimized. As seen
from the data for the period mentioned it is observed that NTPC is deriving
incentives by declaring fuel shortage which is against the spirit of recovery of fixed
charges.
GM WRLDC stated that the matter was deliberated in 52nd CCM & 10th WRP
Committee meeting held on 30th May 2009 at Diu and scheduling was done by
WRLDC in accordance to the decision taken.
Following was decided in case of fuel shortage in respect of NTPC stations in 52nd
CCM & 10th WRP Committee meeting:
(i) Peak Hours would generally be worked out by taking into regional load of
previous days or similar day of the previous week.
(ii) It would be of continuous 5 Hrs. (20 time blocks of 15 minutes)
(iii) The entire year will be divided in two seasons i.e. April to September as summer
and October to March as winter season.
(iv) Peak Hours during the month of April to September – 1800 Hrs to 2300 Hrs.
(v) Peal Hours during the month of October to March – 1700 Hrs to 2200 Hrs.
(vi) Dci will be taken equal to maximum ex-power plant MW schedule specified by
the WRLDC continuously during the above defined peak hours for that day.
GUVNL representative stated they are paying for the interest on working capital for
the storage capacity of coal for 45days and sustained fuel shortage declaration
for three months is not acceptable to them. He further stated that the approved
procedure in the 10th WRPC meeting does not give blanket approval to declare
fuel shortage at the will of NTPC without taking consent from the beneficiaries.
NTPC representative stated that they have followed all the relevant statutory
provisions as regards to declaring the fuel shortages.
Commercial sub-Committee felt that the matter requires further deliberations and
therefore a meeting may be convened.
TCC/WRPC may like to discuss.

ITEM No 17: OUTAGE PROGRAMME OF TRANSMISSION LINES/ELEMENTS A. Line outages planning The line outage planning is becoming very complex day by day, and therefore needs
sophisticated and better planning well in advance. As per IEGC the outage planning
of transmission elements is generally done in OCC. Considering the complexity pre -
OCC meeting is being held in which the line outages planning is done on calendar
month basis. B. Line outages planned vs. implemented:
The status of line outages planned in OCC vs. outages availed and any
deviations from planning or emergency outages for the concerned month are being
discussed in OCC and defaulters are requested to explain the reason of deviation.
C. Code giving procedure:
Since short term market clearance depends on available transmission capacity & is
cleared on day ahead basis, there is a need for better planning. In this regard OCC
formulated the following guide lines for better operation:
(A) All utilities shall confirm on D-2 about readiness to avail outages(where D is date of outage).
(B) WRLDC shall issue code in real time within 10 minutes either to avail or cancel depending on real time conditions.
(C) All utilities do not confirm by D-2, those outages shall be deemed to be cancelled.
D. Inter regional line Outage planning:
As per letter no. 7 /AI/GD/GM-2012, dated 7th Sept., 2012 from Member (GO & D),
CEA, OCC clear NOC for outage of the inter-regional lines in respect of Western
Region. NLDC coordinates inter-regional outages under intimation to
WRPC/WRLDC. WRLDC coordinates in real-time and also along with line outages
already agreed in OCC.

4. APL-SPS, LANCO-SPS is already there. SPS for Agra-Gwalior, Zerda-Kankroli, Badod-Modak is planned. Units to be backed down in WR have been identified.
9.13.1 1 year As National Grid is on the horizon, homogenization of Govt. of India, State Govts system operation philosophy is need of the hour. The
present organizational set up of Load Despatch Centres need to be reviewed. System operation needs to be entrusted to Independent System Operator (ISO). In addition, SLDCs should be reinforced and ring fenced for ensuring functional autonomy 9.13.2 3 months Training and certification of system operators need to be Govt. of India, State Govts
given focused attention. Sufficient financial incentives need to be given to certified system operators so that system operation gets recognized as specialized activity 9.14 2 years Intra-State transmission system needs to be planned and
strengthened in a better way to avoid problems of frequent congestion
STUs
9.15.1 6 months Appropriate amendments should be carried out in Grid CEA Connectivity Standards to restrain connectivity of a generating station or a transmission element without required communication and telemetry facilities. 9.15.2 1 year
The Communication network should be strengthened by putting fibre optic communication system. Further, theCommunication network should be maintained properly to ensure reliability of data at Load Despatch Cenres
CTU and STUs Approvals by WRPC
• Addl. 2672 Kms of OPGW, 14kms of OFC along with wideband communication equipment of adequate capacity for setting up of back-up SLDC at Govindpura, Bhopal, connectivity of Sub-LDC Gandhinagar and Sub-LDC Jetpur to SLDC Vadodara (Gotri) on OFC with suitable end equipments.
• Existing communication equipments (SDH 37nos. & PDH 72nos.) to be replaced at the cost of 3.89 crores
• Installation of PABX System at SLDCs of Western Regions, WRLDC and NLDC
9.15.3 3 months RTUs and communication equipments should have CTU and STUs uninterrupted power supply with proper battery backup so that in case of total power failure, supervisory control and data acquisition channels do not fail 9.15.4 6 months In case of existing generating stations or transmission RPCs, POSOCO
elements without telemetry facility, the same should be New stations are mandated for data transmission through put in place at the earliest. If prolonged operation telemetry before commissioning. without telemetry continues, POSOCO should approach Central Commission
9.16 1 year Large variations are observed in time taken for initiation of unit start up (Boiler light up) by the stations afteravailability of start-up power and also for start ups/light up of subsequent units. While subsequent start-ups were very fast (10-20 minutes) in some of the units, in other cases they took considerably longer time – several hours. Reasons for the delays in attempting first start-up andsubsequent start-ups may be examined by the utilities in consultation with CEA. A standard procedure for preparatory activities and sequence of start up may beput in place by the stations to restore units as early aspossible particularly in contingencies.
CEA, Generating Utilities and RLDCs
9.17 3 months At inter-State level, the entire landscape has changed CEA over past few years. With de-licensing of generation and provision of open access in Electricity Act, 2003 and development of organized electricity markets, lot of generation is coming in the form of merchant generation. Four out of the five regions have been integrated and formation of National Grid is on the horizon. Under such scenario, there is need review the Transmission Planning criteria. 9.18 1 year There is need to reinforce system study groups in power
sector organisations to analyse the system behaviour under different network status/ tripping of lines/outageof generators. Where these do not exist, these should be created
CEA, CTU and STU
9.19 1 month It was felt that a separate task force may be formed,involving experts from academics, power utilities and system operators, to carry out a detailed analysis of the present grid conditions and anticipated scenarios which might lead to any such disturbances in future. The committee may identify medium and long term corrective measures as well as technological solutions to improve the health of the grid
MOP, CEA
9.20 1 year For smooth operation of grid systems, it is absolutelyimportant that all the power generating and distributing stations are connected on a very reliable telecom network. (i) A proper network may be built up preferably using MPLS(multy protocol label switching) which is simple, cost effective and reliable. In remote place where connectivity is a problem, the stations can use dedicated fibre cable from the nearest node (ii) Since POWERGRID has its own fibre optic cables, practically covering all major nodes and power stations, a proper communication/IT network may be built using dedicated fibres to avoid any cyber attach on the power system.
