ITEM No. 1: CONFIRMATION OF THE MINUTES

Shri M M Dhakate, S.E(Opn), stated that Minutes of 469th meeting of Operation &

Coordination Sub-Committee of WRPC held on 10th March 2015 at Nagpur were

forwarded vide letter No. WRPC/OPN/OCC-Minutes/2014-15/2616 dated 18.03.2015.

GM, WRLDC vide letter dated 23.03.2015 for amendments in following items in

respect of MoM of 469th OCC meeting:

QUOTE:“

i) Item No 3.2 B, “Delay in issuing code by WRLDC”

ii) Item No. 8.6 , “Unreasonable Scheduling of NTPC stations” and

iii) Item no 9.10. , “Review of ATC/TTC for each state control area in Western

Region

Item NO.3.2 B : Delay in issuing code by WRLDCThere was no clear agenda on the aforesaid item. However, on the issue of non-

availability of PMU data from Satna station, representative from POWERGRID raised

the issue of non- availability of shutdown the PMU data could not be made available. It

4

470th OCC MINUTES

is to mention that the PMU data from Satna was not available since one year due to

non- establishment of wideband network

WRLDC however, on the issue of clearances of daily outages clearly explained the

methodology adopted during outage co-ordination and stated as follows.

“After getting readiness from utilities, reliability suggestions for all outages are issued

in advance and the list of outages approved for next day is made available to all

concerned through mail as well as goggle sheet. On the day of outage, real time code

is issued after coordinating with the concerned utilities. In Western region itself daily

around 60-70 numbers of outages are handled and for each outages, coordinationneed to be done with two or more agencies. At the same time many emergency

outages are also handled. Handling such large number of outages without

compromising grid security is a challenging job. It is also observed that many a times

the utilities changed their program in the last minute without availing the approved

outages. Instead of generalizing the issue in OCC forum, utilities are requested to

bring any specific case which are delayed for considerable time and the same may be

brought into the forum through proper agenda.”

Item No.8.6: Unreasonable Scheduling of NTPC stationsGM, WRLDC stated that the methodology circulated by NTPC requires further

deliberation with NTPC. WRLDC suggested that they would like to discuss the

methodology with NTPC for implementing an appropriate procedure for taking the

units under RSD.

Item No. 9.10: Review of ATC/TTC for each state control area in Western RegionGM WRLDC stated that, SLDC Maharashtra may do the necessary studies and

declare the ATC of their respective control area. WRLDC agreed to provide necessary

assistance if any for conducting the studies.”

UNQUOTE:The Sub-committee discussed the matter & agreed for modification of 469th MOM as

above.

No other comments have been received. The minutes were confirmed with abovemodification.

ITEM NO.2: REVIEW OF SYSTEM OPERATION DURING THE MONTH OF MARCH2015.

470th OCC MINUTES

2.5 Power Cuts / Load Restrictions

Details of Power Cuts and Regulatory measures during March 2015 as furnished bythe state utilities are given in Annex. 2.5.


2.6 Details of Generating Units under Forced outages

Details of generating units under forced outages during March 2015 are given inAnnex-2.6.


2.7 Details of Generating Units under Planned outages

The details of generating units under Planned Outages during March 2015 are given inAnnex-2.7


ITEM NO.3: OPERATIONAL PLANNING

3.1 Proposed Planned maintenance programme of generating units.

The maintenance programme of generating units for April 2015 & May 2015 was

discussed.

The finalized outage schedule of generating units for the above period and the

modified outages plan is placed at Annexure-3.1.

The Sub-Committee agreed as above.

3.2 A. DELAY IN ISSUING CODE BY WRLDC:

The matter of delay in code issued by system operators & concern raised by transmission

elements outages availing agencies was discussed in 469th OCC meeting & decided that

proper care shall be taken by reliability coordinators & system operator to minimize

wastage of mobilization of 1000’s of man-hours, machineries etc. and if there is real time

problem, the same shall be informed to next OCC meeting with satisfactory reason

thereof.

Member Secretary, WRPC suggested that proper coordination among utilities, WRLDC

reliability coordinating group, WRLDC Control room group & WRPC would help in timely

availing the outage which might leads to minimize the wastage of man power &

machineries.

7

470th OCC MINUTES

CM (SO), WRLDC gave a brief presentation on the existing procedure for outage

coordination and highlighted the associated issues that aggravate the complexity in

facilitating the outage such as involvement of multiple agencies, delay / non-

submission of readiness in D-3 by the utilities for availing the outage, impromptu

request for outage of additional elements over and above those approved (to take

care of induction), delay in restoration of elements already under planned outage

leading to re-scheduling of outage in parallel/same corridor, incomplete Dia due to

pending commissioning of bays or forced outage, dynamically varying grid conditions,

non-availability of telemetry etc. He said that we must learn from the experience of

blackout of Turkey in March 2015, of Europe in Nov 2006 and India in July 2012 and

give due regards to the system reliability while allowing shutdowns.

GM, WRLDC expressed concern that even after issue of reliability consent in D-1 day,

the number of outages actually availed is far less than the number of reliability

consents issued. Also, the average delay in issuing the codes is around 30 minutes

and same can be reduced further if outage timings are staggered.

MS, WRPC said in a large interconnected grid where grid elements are being added

at a rapid pace, SLDCs/RLDCs and NLDC have to see the real-time conditions before

allowing any shutdown. He further added that system security should not be

compromised during outage coordination. He appreciated the responsibility of system

operator (WRLDC) to issue code in real time for multiple outages planned for a day.

After detailed deliberation, it was agreed that compliance to the outage coordination

procedure is essential for availing the outage without compromising grid security. It

was also decided that time of availing the planned outage would be staggered by the

utilities to the extent possible so as to avoid simultaneous requests of multiple

elements starting from 0800 hrs in the morning.

GM, WRLDC ensured that all efforts will be made so that code will be issued with

minimum possible time for the transmission elements which are approved in OCC

meeting after completion of due formalities.

The Sub-Committee agreed/noted for the same.

May 2015 is given in Annex 3.2 B.

The Sub-Committee agreed/noted for the same.

3.3 ANTICIPATED POWER SUPPLY POSITION FOR THE MONTHS – APRIL 2015 &MAY 2015

Details of anticipated restricted & un-restricted demands for the months of April 2015 &

May 2015 are given in Annex 3.3.

The Sub-Committee noted the same.

ITEM NO. 4: OPERATIONAL STATISTICS FOR THE MONTH OF MARCH 2015

for the case of 29th March 2015 which is discussed below. The other minor tripping

details during the month received from WRLDC is enclosed at Annexure-5.

Representative from WRLDC stated that the tripping of multiple elements due to

failure of primary protection at the time of trial charging of 400 kV Akola2-Taptithanda

ckt-2 of MEGTPCL on 29th March 2015 when 765 kV Wardha-Aurangabad ckt-1 & 2

was under planned outage was deliberated in detail. Members noted that 14 EHV

transmission elements tripped in the event leading to isolation of 765 kV and 400 kV

bus at Akola2, tripping of Unit # 2,3, 5 at Rattan Power (Loss: 440 MW), tripping of

9

470th OCC MINUTES

Unit # 8 Koradi-II (Loss : 110 MW), Blackout at Rattan Power, Loss of supply at 400

kV Akola1 and Akola2, Loading on 400 kV Wardha-Parli D/C > 850 MW, Operation of

SPS resulting in backing down of 100 MW at Mouda plus Load shedding in Southern

Region and 80 MW load distress shedding to control overloading of 220 kV lines from

Akola. It was observed that after the contingency, MW and MVAr support was

instantaneously available from Southern Region due to reversal of power flow on 765

kV Solapur-Raichur D/C and 765 kV Pune-Solapur.

GM, WRLDC expressed concern on the failure of primary protection and lack of basic

due diligence in charging of Akola2-Taptithanda ckt-2.

Member Secretary, WRPC said that such incidents are a threat to grid security and

the event should be examined in detail and proposed to be discussed in the next

Protection Committee meeting scheduled on 21st April 2015. He urged all utilities to

ensure compliance to the laid down procedures for first time charging and

commissioning of new elements.

at the www.wrpc.gov.in.

Member Secretary, WRPC stated that LGBR shall be reviewed on quarterly basis for

further fine turning. Next review will be on the last quarter of the June 2015.


ITEM NO. 8.4 READINESS OF SLDC AT GOA, OTHER SLDCs AND WRLDC FORUPGRADATION OF EXISTING SCADA/EMS SYSTEMDuring 28th WRPC meeting it was decided that the status of progress of SLDC’s &

Back-up SLDC’s of WR constituents /WRLDC would be regularly monitored in monthly

OCC meeting.

The present status of progress of SLDC’s & Back-up SLDC’s of WR constituents

/WRLDC attached at Annexure – 8.4. All the constituents are requested to update inattached format.

The Sub-Committee agreed as above.

ITEM NO. 8.5 : CONTINUOUS BACKING DOWN OF POWER FROM SASAN UMPP

Sasan Power Ltd. informed that cheapest power from the Sasan Ultra Mega Power

Project is being continuously backed down primarily by Haryana, Punjab, Rajasthan

and Delhi. For the similar issue faced by NTPC power plants in the recent WRPC and

OCC meetings, it is understood that a methodology has been devised to address unit

is NOT scheduled below technical minimum capacity. Considering above, Sasan

Power Limited (SPL) requests WRLDC and WRPC that same should be made

applicable for Sasan UMPP which is also a Inter-State Generating Station. In this

regard, Sasan Power Limited has highlighted backing down related issues with the

beneficiaries in the Procurers meeting. As advised during the OCC meeting held

on 10.03.2015, a separate meeting is being arranged with Procurers and outcome of

the meeting would be shared. Hence, it is requested to flag this issue till a solution is

arrived at. Further, SPL requested that technical minimum of all generating stations

(including State Gencos) be audited by third party in line with what Maharashtra who

18

470th OCC MINUTES

has experience in this direction and requested the same be adhered to.

During the presentation, WRLDC shown a plot of DC vs schedule of Sasan during

March 2015. It was noted that there was surrender of power by small quantum by

utilities in Sasan on 1st and 7th March 2015 due to inclement weather conditions and

demand crash. Member Secretary, WRPC and GM, WRLDC opined that on all other

days the entire DC of Sasan was getting scheduled. SE, SLDC-M.P. expressed

concern on large variation in DC of Sasan leading to frequent start and stop of their

own units. Sasan Power was advised to make efforts to ensure consistent generation

availability from Sasan.

He requested SASAN to take up with procurer from NR to formulate policies regarding

scheduling to technical minimum in line with decision taken in meeting on 30th March

2015 regarding CGPL technical minimum scheduling.

The Sub-Committee members noted as above.

ITEM NO. 8.6: WORKSHOP ON BLACK START RESTORATION PROCESS

A Workshop on Black Start Restoration Process in MP System was successfully

organized by SLDC Jabalpur on 25th March 2015. Approximately 85 participants

attended the above workshop.

Member Secretary, WRPC suggested SLDC MP to compile the discussion/matter

during the work shop for further reference.

SLDC, M.P. agreed to compile and forward the recommendations of the workshop.

GM, WRLDC said that the scheme for extending start-up supply to the large size units

of the new thermal generating stations connected at 765 kV or 400 kV level should be

identified at the planning stage itself. Various issues associated with retaining the

connectivity with STU network at lower voltage level established during construction

stage were discussed. Several members opined that this arrangement could help in

extending start-up supply during system restoration.

CE, CSPTCL stated that regulatory provisions for implementing the above suggestion

would be required.

CE, SLDC Gujarat said that the issue of extending start up supply to CGPL from

220/400 kV ICT at Nanikhakar under system restoration state has been under

19

470th OCC MINUTES

discussion. The ICT would normally be charged only from one end and the O&M

charges could be shared by all beneficiaries of CGPL.

It was decided that CGPL would submit a comprehensive proposal (regarding

installation of 220/400 kV ICT at Nanikhakar for extension of start-up supply to CGPL

units) for further deliberation and approval by the TCC/WRPC.

RattanIndia Power Ltd (RPL) raised concern for its 5x270 MW Nashik TPP to operate

during Black-start Restoration process, as STU, MSETCL has allowed connectivity for

Nashik TPP on 400 KV transmission line from Nashik TPP to Babhaleshwar

substation with prior disconnection of 220 KV LILO on MSETCL Eklahare to

Babhaleshwar transmission line at Nashik TPP. As such, due to physical

disconnection of 220 KV LILO line alongwith 400/220 KV ICT, constructed earlier in

order to avail Start-up power, RPL may face constraints in start-up power availability

during Black Start restoration process.


ITEM NO. 8.7: OCC APPROVAL FOR ATTENDING MAINTENANCE WORKS IN400KV BAY OUTAGES

WRTS-II, PGCIL informed vide letter dated 04th April, 2015 that, WRLDC had advised

to obtain OCC approval for issuing code for outage of 400kV Main / Tie bays, for

maintenance works. In one and half breaker scheme, during outage of main / tie bay,

the line/ICT remains in service through its tie/ main CB, and there is no element

outage involved & power supply position is not affected. As such, it is felt that there is

not much requirement of OCC approval of 400kV Bay outages.

Also, there are large no. of 400kV Main / Tie bays in service in various substations

and their inclusion in main OCC agenda will un-necessary increase the OCC list and

time for due diligence in element outage will get affected.

As per IEGC code 2010, clause no. 5.7.1 (a), the outages are planned on element

basis.

20

470th OCC MINUTES

PGCIL have requested that earlier practice of granting 400kV Bay outages by WRLDC

based on real time conditions may please be continued instead of including these in

OCC agenda.

WRLDC during presentation gave examples of grid incidences due incomplete dia due

to outage or non-commissioning of Main/Tie bays at several of the new substations in

WR resulting in unexpected / undesirable tripping of elements during facilitating

planned/emergency outage.

MS, WRPC opined that the construction activities in various substation of WR are in

full swing and the availability of bays needs to be checked thoroughly before

permitting shutdown of other bays.

After discussion it was decided that all planned shutdown of bays in EHV substations

(400 kV and above) would also be forwarded by respective utilities for discussion and

concurrence in the monthly OCC meeting.


ITEM NO: 8.8 SCHEDULING OF TECHNICAL MINIMUM SHARE FROM ISGS ANDSUDDEN WITHDRAWAL OF URS SHARE OF ISGS.CE, SLDC, Gujarat vide letter dated 06.04.2015 intimated that during 467th OCC

meeting held on 16.01.15 at WRPC, Mumbai, the following was decided with respect

to technical minimum scheduling of ISGS stations of NTPC:

Constituents will give their requisition for more than 30% of their entitlements

for on bar generation for all NTPC ISGS stations.

In case total requisition for a particular on bar unit in a station is lesser than

technical minimum, then deficit for meeting TM would be conveyed by WRLDC

to its beneficiaries.

Beneficiaries will have to send revised requisition so as to meet TM on pro-rata

basis

commensurate with their entitlement percentage by 21:00 Hrs. After 21:00 Hrs,

WRLDC will issue the final schedule i.e. R-1, as received from beneficiaries.

WRLDC will coordinate and issue reasonable schedule based on revised

requisition taking care of ramping up / ramping down and the ratio between

minimum and maximum generation levels as envisaged in IEGC 6.5.14.

21

470th OCC MINUTES

It happens many times that during night hours, the technical minimum share of other

constituents was scheduled to Gujarat State especially from NTPC Mauda Power

Station. It is also observed that many constituents are scheduling their power from

coal based station as a peaking station and in night hours, they are not cooperating to

absorb / schedule their Technical Minimum share.

It is utmost necessary that the practice of using coal based stations as peaking

stations shall have to be stopped. In case total requisition for a particular on bar unit in

a station is lesser than technical minimum, then deficit for meeting TM will have to

commensurate with their entitlement.

Also, it is observed many times that the intimation of URS withdrawal due to

requisition of power by the beneficiaries is received at the last moment or posted on

WRLDC web site just prior to the block of implementation. When there is a sudden

withdrawal of URS power exceeding a quantum of 100 MW especially during peak

hours, it is very difficult to manage the power requirement of the State for the

beneficiary who is availing URS.

Hence, it is necessary that URS shall be withdrawn / scheduled in steps of 100 MW or

less per block so that it would be easier for the State availing URS to manage power

requirement. Also, the intimation of URS revision shall be posted with pop-up block on

WRLDC website to acknowledge changes in schedule easily.

GM (OS & Comml) NTPC informed the forum that:-

(1) In order to reduce energy cost of Mouda, FSA has been signed with SECL on

24.03.15 (in place of MCL). This was as per recommendations of Inter Ministerial

Task Force (IMTF) for rationalization of coal sources. Further the coal realization

from WCL has also started from February 2015. This will ensure availability of

more domestic coal. With these initiatives energy charges of Mouda is expected to

come down in next 2-3 months.

(2) Govt. of India vide MOP/NG/Ref. No./PPAC/Gas pricing/april-Sept.’15 dated

31.03.15 has fixed up the Gas Fuel price of $ 4.66/mmbtu from 1st April 2015 to

30th Sept.’15, Accordingly variable charges of Kawas and Gandhar Gas power

stations have reduced. The same will approximately be 303p/kwh.

22

470th OCC MINUTES

(3) NTPC has started Hydro Power Generation from its 1st 800 MW Hydro power

station “KOLDAM” situated in Himachal Pradesh, out of 4 units of 200 MW, three

units have been synchronized and achieved full load.

CE, LD, MPPTCL vide letter dated 26.03.2015 (copy enclosed at Annexure-8.8)

suggesting modifications/corrections in the MOM of 28th WRPC meeting, it was clarified

by SE(O), WRPC that condition of 30% in R0 is only for the beneficiaries who schedule

around 100 % of their entitlement during peak conditions. If flat requisition of “0” is given

by any beneficiary then it would be fine and would not count for any violation to agreed

methodology.

Member Secretary, WRPC stated that the earlier decisions taken in OCC’s & WRPC will

be followed in the above matter.


ITEM NO. 9 : ITEMS FROM WRLDC:

ITEM NO 9.1: TRANSMISSION CONSTRAINTS WITHIN MAHARASHTRA SYSTEMThe issue of transmission constraint within Maharashtra system has been under

deliberation in the past several OCC meetings. The same was also discussed during

the 27th and 28th TCC/WRPC meeting. During the discussions, it emerged that several

transmissions elements downstream of Aurangabad (PG) / Taptithanda (MSETCL)

towards Pune and Bableshwar are heavily loaded viz.

• 765/400 kV ICTs Aurangabad (PG)

• 400 kV Aurangabad-Waluj D/C

• 400 kV Aurangabad-Pune D/C

• 400 kV Waluj-Bableshwar

Recently the following new elements have been synchronized / commissioned within

Maharashtra.

1. LILO of 765 kV Tiroda-Akola2 at Koradi-III

2. 765 kV Tiroda-Koradi-III ckt-2

3. 765 kV Koradi-Akola2 ckt-2

4. 765 kV Wardha-Aurangabad ckt-3 and 4

5. 400 kV Akola2-Taptithanda ckt-2

23

470th OCC MINUTES

6. 400 kV Rattan Power-Akola D/C

7. 765 kV Solapur-Pune S/C

However it may be seen that except 765 kV Pune-Solapur S/C all the above elements

are located upstream of Aurangabad. Thus, the desired relief on the congested

corridor downstream of Aurangabad (PG) towards Pune/Bableshwar is still awaited.

During the joint simulation studies conducted at WRLDC following measures were

suggested for relieving the congestion downstream of Aurangabad.

a) Commissioning of 400 kV Dhule bays for BDTCL line (Action: MSETCL)

b) 220 kV outlets from Taptithanda and Aurangabad-PG (Action: MSETCL)

c) 220 kV outlets from Pune_PG and Warora (Action: MSETCL)

d) Load trimming scheme at Waluj and Boiser (Action: MSETCL)

e) Temporary by passing 400 kV Waluj to form 400 kV Aurangabad (PG) to Pune

(PG) D/C instead of 400 kV Aurangabad-Waluj D/C and 400 kV Waluj-Pune

D/C (Action: POWERGRID and MSETCL)

MSETCL said that the Dhule bays are expected to be commissioned by May 2015

end. POWERGRID agreed to explore possibility of bypassing 400 kV Waluj and

connecting 400 kV Aurangabad_PG to Pune GIS after completion of 400 kV Dhule

bays and LILO of 400 kV Waluj-Pune_AIS D/C at 765/400 kV Pune GIS and revert

back.

Member Secretary, WRPC suggested that joint survey would be done by MSETCL,

PGCIL, WRLDC & WRPC for exploration of connectivity.

RPL informed that due to various transmission constraints within Maharashtra State,

power from its 5 x 270 MW Amravati TPP is presently restricted at 750 MW Ex-Bus

against PPA commitment of 1200 MW with MSEDCL.

WRPC forum informed that since RPL is embedded IPP within Maharashtra State and

as the Ex-Bus power restriction is imposed by STU, MSETCL, issue to be resolved by

STU, MSETCL only.


24

470th OCC MINUTES

ITEM NO. 9.2 : CONSTRAINTS IN GRID OPERATION DUE TO NON-AVAILABILITY OF TELEMETRY FROM MSETCL/MAHAGENCO STATIONSNon-availability of telemetry from large number of EHV stations of MSETCL andMahagenco has been flagged by WRLDC and is being deliberated in the OCC forumfor more than a year. It is a matter of concern that the despite repeated assurancesfrom representatives of Maharashtra the issue remains unresolved. Consequently theobservability of Maharashtra system is poor and achieving convergence of the StateEstimator is also a challenge.In the absence of Circuit Breaker Status, Bus voltage, line flow (MW and MVAR),severe constraints are being experienced by WRLDC control room personnel in real-time supervision and operation of the grid. State Estimator is also not converging Itmay be recalled that there have been several disturbances involving tripping ofmultiple transmission elements and consequent load/generation loss in Maharashtra.The restoration activities as well as post-facto analysis of events were severelyconstrained due to non-availability of telemetry.Coordination of outage of EHV elements is also hampered due to non-availability ofcircuit breaker status and analog values from various stations in Maharashtra.GM, WRLDC expressed concern on the non-availability of telemetry from severalsubstations of Maharashtra particularly 400 kV Taptithanda, Warora, Chandrapur andLonikhand despite continuous follow up and repeated assurances by MSETCLrepresentatives.Member Secretary, WRPC opined that MSETCL should forward a clear timeline ofresolution of telemetry issues of Maharashtra.CE, SLDC-Kalwa confirmed that all the pending telemetry issues of Maharashtrawould be resolved by end of May 2015.The Sub-Committee noted as above.

ITEM NO. 10: DATE AND VENUE OF NEXT OCC MEETING469th OCC reviewed the meeting roaster and finalized sheet is enclosed at Annexure-

10. Accordingly, it was proposed to host 471st OCC by Tata Power on 13th May, 2015.

Tata Power expressed inability to host the 471st OCC meeting, therefore it will be held

at WRPC office, Mumbai. The TATA Power turn will be as modified roster attached at

Annexure -10.

As per roster, it is proposed to host 472nd OCC by Torrent Power Ltd., Ahmedabad in

the month of June 2015.
