AGENDA NOTES FOR 7th MEETING OF WESTERN REGIONAL POWER COMMITTEE TO

BE HELD ON 3rd MAY 2008 AT MAHABALESHWAR

ITEMS FOR DISCUSSIONS

ITEM No.1: CONFIRMATION OF THE MINUTES OF THE 6th MEETING OF

WRP COMMITTEE

1.1 The minutes of 6th meeting of WRP Committee held on 11th January 2008

at Port Blair were sent to the Members vide letter No. A.S./Min./WRPC/2008-

1010 dated 31st January 2008.

1.2 GM (O&M), WR-I, PGCIL vide letter dated 11th Feb. 2008 (copy enclosed

at Annexure-1.2) have proposed amendment in Para 12.3 of Item No. 12

“Testing of Special Energy Meters” of the minutes.

The Committee may discuss and confirm the minutes of the meeting. ITEM No.2: BACKUP COMMUNICATION LINKS FROM SLDCs &

STRATEGIC LOCATIONS IN THE NETWORKS OF ULDC SCHEME

2.1 In order to improve the reliability of data communications between

WRLDC and SLDCs, a scheme for backup communication links from SLDCs and

strategic locations in the networks of ULDC was proposed by WRLDC. As

desired by the WRP Committee in its 5th meeting held on 6th October 2007, the

scheme was discussed by a committee of Western Regional Constituents,

WRLDC and WRPC Secretariat on 17th Dec. 2007. The constituents agreed to

the need for back-up communication links between SLDCs / Strategic locations

and WRLDC. At the same time need for back-up links between Sub-LDCs to

SLDCs was also felt. However, instead of providing the stand by arrangement


through bandwidth provided by PGCIL Telecom network, it was proposed to have

these links through VSAT/Radio link. In addition OPGW link between Gotri to

Jambuva & Gotri to Asoj was also agreed to.

2.2 The above recommendations were put up to the TCC in its meeting held

on 10th January 2008, wherein PGCIL pointed out that the cost of the revised

proposed scheme would be very high. The other points which also emerged in

the TCC meeting was that (i) the expenditure for sub-SLDC to SLDC link should

be borne by the concerned SLDC and not loaded in the regional system and (ii)

the commercial implications of VSAT vis-a-vis earlier proposal by PGCIL should

be examined. WRP Committee endorsed the decision of TCC and directed that

the proposal be discussed initially at working level Committee and its

recommendations shall be put up to TCC / WRPC for the decision.

2.3 In this context WRLDC vide letter dated 7th March 2008 forwarded the

comparative cost estimates for the two alternatives, viz. considering bandwidth

from PDT and VSAT worked out by LD & C, CC, PGCIL. This issue was further

discussed by the above referred committee in a meeting held on 15th April 2008.

After considering the various technical fesibilities vis-à-vis financial implications,

the following scheme for back up communication was recommended by the

committee for consideration / approval of WRPC:

(i) 9 E-1 to be located between Asoj and Kalwa (consisting of 6 Nos.

E1 for traffic, 1 No. E1 for CPCC and 2 Nos. E1 for network

management system) and STM-16 equipment to be provided at

Asoj S/s of GETCO. Fixed Cost – Rs. 7 lakhs. Recurring cost Rs.

32.4 lakh per year (inclusive of service tax)

(ii) Radio link suitable for min. 9 E-1 in delicensed frequency band from

Kalwa to Marol (WRLDC, Mumbai). Fixed cost Rs. 5 Lakh (subject

to feasibility of link)


(iii) OPGW cable from Jambuva to Gotri & Gotri to Asoj – Fixed cost Rs

140 Lakh.

Record Notes of discussions held at WRPC office, Mumbai on 15th April 2008

regarding Backup Communication links from SLDCs & Strategic Locations

in the networks of ULDC scheme are enclosed at Annexure- 2.3.

WRP Committee may discuss and approve. ITEM No 3.: PERFORMANCE OF WR GRID DURING JANUARY 2008 TO

MARCH 2008 3.1 System Performance

During the period January 2008 to March 2008, the grid operated in the

frequency range 49.0 Hz and 50.5 Hz for 75.93 % of time. The percentage time,

when the frequency was within this range varied between 73.02% and 77.62%.

During March 2008, frequency remained below 49.0 Hz. for 26.95% of time. The

details of frequency profile during the above period is enclosed at

Annexure-3.1 (a).

WRLDC have reported that the load relief forthcoming due to operation of UFRs

is quite inadequate. They have observed that in many cases delayed load relief

comes due to manual load shedding, whereas the relief is expected to come

instantaneously at 48.8 Hz and 48.6 Hz. All the constituents are therefore

requested to ensure that UFRs are kept operative to provide full quantum of

recommended load relief.

WRPC Engineers inspected UF relays in Chhattisgarh and Gujarat States in

February 2008 and April 2008 respectively at six substations and for 19 feeders.

The UFRs provided there were found to be in operating conditions. However, it

was observed that in CSEB system the load relief obtained on their operation

was on the average of the order of 35% of the normal load relief expected.


The details relating to registered demand/unrestricted demand, energy

availability and energy requirement during the above period are at Annexure-3.1

(b). The maximum unrestricted demand of the region was 39780 MW as

recorded during January 2008. The maximum demand met during this period

was 29746 MW, which was registered during February 2008. The peak shortfall

of the Western Region ranged from 9183 MW to 10678 MW. Capacity shortage

during this period was of the order of 23.59 % to 26.84 % and energy shortage

was in the range of 18.90% to 20.43 %.

During the 6th WRPC meeting held on 11th January 2008, it was noted that the

issue of prevailing low frequency scenario in N-E-W interconnected grid was

discussed in a joint meeting of NR and WR constituents taken by Chairman, CEA

on 4th December 2007 at New Delhi. In this meeting NTPC were requested to

pursue augmentation of RLNG supply to help improvement of power supply

position in Western Region. Further, WRLDC/NRLDC had been authorized to

schedule the un-requisitioned liquid power to the overdrawing utilities. During the

6th WRPC meeting, it was observed that despite above meeting of 4.12.2007, low

frequency scenario had continued to prevail. The WRP Committee therefore,

suggested that a second joint meeting of WR and NR may be taken by

Chairman, CEA to address issue of low frequency. Accordingly, a joint meeting of

WR and NR constituents was taken by Chairman, CEA on 5th February 2008 at

New Delhi to discuss issues related to low frequency operation of the grid due to

overdrawl by some constituents.

During the above meeting of 5.2.2008, it was observed that States of UP,

Haryana, J&K, Rajasthan and Punjab in Northern Region and Madhya Pradesh,

DNH and DD in Western Region and Bihar and Jharkhand in Eastern Region

were generally overdrawing. The representatives from the overdrawing states

explained the extent of load regulatory measures taken by them and the position

of power availability in their respective systems. After detailed deliberations

following States were requested to take additional load regulatory measures to


give additional load relief with a view to maintaining their drawl as per the

schedule;-

Rajasthan : 300 MW

Haryana : 100 MW

Punjab : 100 MW

NTPC were requested to make all efforts to arrange RLNG and liquid fuel to

utilise the full capacity of gas based stations.

The Committee may like to discuss.

3.2 Voltage Profile The month-wise detail of voltages at important 400 kV substations during the

month of January 2008 to March 2008 is at Annexure-3.2. During this period, low

voltages were recorded at 400 kV Gwalior, Indore and Jetpur substations of the

order of 369 kV (January 2008), 378 kV (March 2008) and 372-379 kV (January

to March 2008) respectively.

The high voltages were recorded at Bina, Indore, Itarsi, Karad, Dhule and

Gwalior ranging between 426-436 kV and of the order of 813 kV at 765 kV Seoni

S/s.

Actions taken to ensure smooth voltage profile in the grid are as follows:

i) Two RBPH machines of SSP are being operated in Synchronous

Condenser mode whenever required on advise from WRLDC.

ii) 63 MVAr reactors on 400 kV Bina-Nagda D/c line (one on each circuit)

were taken into service.

iii) 80 MVAr Bus Reactor of 765 kV Seoni-Sipat line at Seoni end was

energized.


During 6th WRPC meeting, status on expected commissioning of reactors to

control high voltages during the low load periods by the PGCIL/State utilities was

intimated. Further, as per the information made available by the above agencies

subsequently, the status is as below:

i) The installation by PGCIL of 63 MVAr reactor at 400 kV Damoh sub-

station was expected to take place in March 2008 whereas the

installation and commissioning of 125 MVAr bus reactors each at 400

kV Khandwa and Dehgam sub-stations is expected to complete by

June/July 2008.

ii) Shunt Controllable reactor at 400 kV Padghe s/s in Maharashtra is

likely to be commissioned by MSETCL in October 2008.

iii) The installation of 125 MVAr bus reactor each at Dhule, Indore, Kasor

sub-stations by MSETCL, MPPTCL and GETCO and 80 MVAr bus

reactor each at Karad and Nardipur substations by MSETCL and

GETCO as was agreed and later noted in the 4th WRPC meeting is yet

to take place. During 5th WRPC meeting MSETCL had intimated that

orders for 2x50 MVAR line reactors at Dhule end for 400 kV SSP-

Dhule D/c line were placed. Later, MSETCL informed in OCCMs of

WRPC that these are expected to be commissioned by October 2008.

PGCIL, MSETCL, MPPTCL and GETCO may indicate further progress made and expected date of installation and commissioning of reactors at the above locations, as an early commissioning of these reactors would help in smoothening of high voltage profile in Western regional grid.

Members may kindly discuss.


3.3 PROGRESS OF INSTALLATION OF SHUNT CAPCITORS IN WESTERN REGION DURING THE YEAR 2007-08 AND PROGRAMME OF THEIR INSTALLATION IN THE YEAR 2008-09.

During the year 2007-08 (April 2007 to March 2008) the WR utilities installed 526

MVAr capacitors in Western Region viz. Madhya Pradesh 396 MVAR, CSEB 110

MVAR and TPC system 20 MVAR.

To work out requirement for installation of shunt capacitors for the year 2008-09,

the WRPC study Committee met on 1.10.2007 and again on 4th & 5th March 2008.

Based on the system data provided by WR utilities and the deliberations on results

of the capacitor study conducted by WRPC Secretariat, the study Committee

evolved the requirement of HT capacitors in the region. The summary of proposed

programme is as below:-

Sr. No. System MVAR requirement for 2008-09 1 Gujarat 435 2 Maharashtra 375 3 Madhya Pradesh 110 4 Chhattisgarh 90 5 Total (WR) 1010

The station-wise locations for each of the above States is at Annexure-3.3 Members may kindly discuss and approve the requirement as above. ITEM No.4 : REVISION OF SETTINGS OF THE df/dt UFLS RELAYS IN THE WR During the 6th WRPC meeting, the Committee had noted the recommendation

made during a joint meeting, which was held between RPCs and RLDCs of NR,

WR and ER on 27.11.2007 at Kolkata to discuss the proposed revision in df/dt

settings in view of N-E-W grids having been interconnected with number of A.C,

interconnectors. The Committee had also further noted the opinion of OCC of

WRPC on the above recommendation made in its 382nd OCCM held on

12.12.2007. WRLDC in the TCC meeting held on 10.1.2008 had suggested that

the currently prevailing df/dt settings which were earlier revised in August 2006

have been working as per expectations under contingency conditions, therefore,


the same settings might continue. However, in view of the above deliberations,

WRP Committee in 6th WRPC meeting had advised WRLDC to discuss the matter

with NRLDC and ERLDC and come out with the jointly agreed df/dt settings for

final view by the Committee and implementation of the revised settings thereafter.

WRLDC vide letter dated 31.3.2008 intimated that detailed deliberations were held

by them with NRLDC and ERLDC keeping in view all possible N-E-W grid

conditions concerning the interconnected grid security. As a result the df/dt settings

agreed between WRLDC, NRLDC and ERLDC are as follows:-

Load Relief (MW) Setting of

df/dt relay

Settings (Hz)/(Hz/sec)

WR NR ER

Stage I 49.9/0.1 2000 2000 800 MW (600 MW ER+200 MW SR) at 0.125 Hz/s at 49.9 Hz

Stage II 49.9/0.2 2000 2000 Nil

Stage-I - df/dt to protect the combined NEW grid from loss of generation of a large

power station.

Stage-II- df/dt to protect the split grid from loss of generation of a large power station.

Stage-III- df/dt to protect the individual regional grid/state grid from loss of generation in the event of isolation is presently set at 49.2 Hz/0.4 Hz/s.

WRLDC had suggested that the above Stage-III df/dt setting needs to be upgraded

to 49.9 Hz/0.4 Hz/s in line with the above revision.


The corresponding constituent-wise df/dt settings for WR are as follows:-

Setting of df/dt relay

Settings (Hz)/(Hz/Sec)

Total Load Relief in Region (MW)

Load shedding (MW) to be effected by

GETCO MPPTCL MSETCL CSEB TPC

Stage I 49.9/0.1 2000 1006 361 546 27 60 Stage II 49.9/0.2 2000 905 355 621 37 82 Stage III 49.9/0.4 2472 1001 392 686 120 273 Total 6472 2912 1108 1853 184 415

In 386th OCCM of WRPC held on 11.4.2008, WRLDC explained the df/dt UFLS

settings agreed between the RLDCs as above. WRLDC further intimated therein

that as there is not much literature on df/dt relay operating experience, the settings

recommended as above may be adopted and performance observed for next six

months and then review the same when operating experience is gained and

reliable data is available. The OC sub-Committee of WRPC agreed to the same.

Members may kindly discuss and approve the recommended revised df/dt settings so that the same are implemented thereafter. ITEM No.5: UTILISATION OF 220 KV UJJAIN-KOTA AND UJJAIN-MORAK

LINES

Hon’ble CERC in petition no. 85/2007 (suo-moto) in the matter of “Proposed

approach for sharing of charges for and losses in inter-state transmission

system” vide order dated 28.03.2008 stressed the need to identify the state

owned inter-regional lines and to operationalise such lines in synchronous mode.

They have observed that 220 kV Ujjain-Kota line is one such link which can

reinforce NR-WR interconnection. The commission directed RPCs to identify

such lines and take necessary action to convert them into synchronous

operation.


In this context, WRPC secretariat have already addressed letter to Secretary,

Deptt. Of Energy, Govt. of Madhya Pradesh requesting to advise the concerned

authorities of MP to expedite finalizing of the plan to operationalise 220 kV Ujjain-

Kota and Ujjain-Morak lines at the earliest in coordination with RRVPNL.

WRLDC has also taken up the matter with MPTRANSCO and requested them to

expedite settlement of bilateral commercial issues with Rajasthan so that the

parallel operation of above lines may start.

WRP Committee may like to note. MPPTCL may intimate action plan to synchronise these lines, if any. ITEM No.6: FUNDING OF WRPC SECRETARIAT 6.1 The matter regarding funding of WRPC secretariat was discussed in the

Special Meeting of WR constituents held at New Delhi on 13th March 2006 and

reimbursement of expenditure in respect WRPC secretariat to GoI was agreed

to. Regarding sharing of expenditure by the constituents of WR, the matter was

discussed in 1st meeting of WRP Committee held on 8th June 2006 and it was

agreed that the same will be equally shared by each WRPC member except

CEA, NLDC, RLDC and WRPC Secretariat. This expenditure as decided is

presently being reimbursed to the Government of India on quarterly basis.

6.2 In order to stream line the reimbursement procedure and to reduce the

number of transactions, it is proposed that instead of quarterly reimbursement,

total annual payment may be made in a single installment. Any variation between

sanctioned budget estimates and actual expenditure may be adjusted in the

subsequent year. This procedure is already in vogue in Northern, Southern &

Eastern Regions.

WRP Committee may like to approve this arrangement.


ITEMS FOR INFORMATION

ITEM No.7: ANTICIPATED POWER SUPPLY POSITION FOR THE PERIOD APRIL 2008 TO JUNE 2008 The anticipated power supply position in the region for the period from April 2008

to June 2008 is furnished at Annexure-7 for information of the members. The

regional demand is likely to remain high till mid-June 2008. The peak demand

deficit is likely to be of the order of 5600-11050 MW, whereas energy deficit of

the order of 60 -230 MUs per day. The anticipated regional peak demand is in

the range of 35600-40800 MW. The anticipated peak demand shortages for

Gujarat, Chhattisgarh, M.P., Maharashtra, Goa, DD and DNH would be in the

range of 4300-4750 MW, 100-600 MW, 350-1050 MW, 3000-6750 MW, 130-165

MW, 85-100 MW and 140-195 MW respectively during the above period.

In view of the above, all the utilities shall require to ensure that system frequency,

voltage profile and transmission system loadings are maintained within the

permissible limits in the interest of security of the interconnected grid. All the

utilities are, therefore, requested to maximize power availability to overcome

overdrawals at low frequency. All generating utilities may also ensure that the

entire generating capacity is fully available. Also no capacity should be left

unrequisitioned from all ISGS stations. NTPC shall ensure availability of

adequate quantity of Gas/LNG to enable full utilization of their gas-based plants.

To meet any contingent conditions, it shall however have to be ensured that the

existing UFR and df/dt relays under the AUFLS scheme are operative at the

recommended settings and the desired load relief is obtainable.

The voltages profile of the grid may tend to drop below lower permissible-levels.

Therefore it shall have to be ensured that all HT capacitor banks at EHV sub-

stations in the region are in service. SSP may follow real-time operational

instructions by SLDCs/RLDC by operating RBPH machine(s) in synchronous


condenser mode for providing adequate reactive power support and all thermal

generating units in the vicinity of lower voltage profile shall require to maximize

generation of reactive power within their capability limits so as to help in

controlling low voltage in the grid.

Members may like to note/discuss.

ITEM No. 8: PAYMENTS OF UI AND REACTIVE ENERGY CHARGES

8.1 As per the information received from WRLDC, the status of payment to UI

pool account and Reactive Energy Pool account as on 16.04.2008 of the current

financial year is given below: -

The State utilities those are required to pay dues towards UI charges may indicate the plan for liquidation. 8.2 Regarding outstanding dues form Northern Region, this is to intimate that

in accordance with the resolution adopted by WRP Committee during its

6th meeting held on 11th Jan. 2008, Chairman, WRPC / CSEB addressed letter


dated 25th February 2008 to Secretary (Power), Govt. of India (copy enclosed at

Annexure-8.2), bringing to his notice the concern of WR constituents regarding

non-payment of UI charges by some of the NR beneficiaries. It was suggested

that dues towards UI charges against overdrawl might be managed to be paid to

the recipient entities from the quota of central sector assistance of those States

which are not making UI payment and the amount so paid be adjusted while

releasing final payment of central assistance to these States. MoP was

requested to develop mechanism for releasing such payment directly from

Central assistance.

Further, in the matter of default of Unscheduled Interchanges (UI) charges for the

energy drawn in excess of the drawal schedule and in the matter of Power

Development Department, Govt. of J & K, Petition No. 132/2007, Hon’ble CERC

in an order dated 29th Feb, 2008 directed PDD, J & K to open a revolving LC for

assuring regular payment of Rs. 40 Crore every month to the regional UI

account, till liquidation of dues (to the tune of Rs. 410.25 Crores). Similarly, in the

matter of default in payment of UI charges by Uttar Pradesh Power Corporation

Ltd., Petition No. 131/2007, Hon’ble CERC in an order dated 11th April 2008

directed UPPCL, to take necessary action to liquidate the entire UI arrears in six

(6) monthly installments by paying Rs. 128 Crores every month from May 2008.

The Commission also directed NRLDC to draw up in consultation with Member

Secretary, NRPC, a practicable scheme for physical curtailment of supply to

UPPCL, for enforcement in case necessary.

Committee may like to note. ITEM No. 9: CONNECTIVITY TO IPPs WITH LILO OF EXISTING GRID LINES 9.1 CSEB vide letter No. CSEB/MIC/43 dated 19th February 2008 (copy

enclosed at Annexure- 9.1) have pointed out that while granting open access to

M/s Amarkantak LANCO, the connectivity to grid have been granted at Korba

through LILO of 400 kV Korba (NTPC) - Sipat line. Similar is the case in the


case of Mahan power project of ESSAR in Madhya Pradesh where LILO of

existing 400 kV Korba-VSTPP has been proposed. CSEB opined that extension

of such facilities for connectivity to IPPs is not desirable as (i) the control of the

line goes in the hands of the IPP, (ii) it affects the serviceability of the system, (iii)

it effects the metering & protection of the original line, making it more

complicated and (iv) line loadings may pose problems especially if alternate line

is under maintenance/shutdown/breakdown.

9.2 In this context it is intimated that Long Term Open Access Applications in

Western Region are being discussed by CTU (PGCIL) regularly in meetings with

all WR constituents and the minutes of the meeting are issued by PGCIL. The

issue of open access to M/s LANCO Amarkantak PPP was discussed in 9th

meeting of WR constituents regarding LTOA in WR held on 30.7.2007.

Considering limited time period left out the above LILO was allowed. However,

on completion of identified system strengthening works, LILO arrangement of

Korba STPS-Sipat at Pathadi shall be removed and restored back to its original

configuration by M/ LANCO Amarkantak / PTC on their own cost. Similarly, in

case of LTOA to Mahan, Essar Power M.P. Ltd, the committee decided to

facilitate grid connectivity of Mahan Project, initially, by LILO of one ckt. of 400 kV

Korba STPS- Vindhyachal as development of 400/765 kV pooling station (near

Sipat) may require long time and may be difficult to complete works before

commissioning of generating unit at Mahan. However, on completion of identified

WR system strengthening works etc., LILO arrangement of Korba STPS-

Vindhyachal line at Mahan TPS shall be removed and line will be restored in its

original configuration by M/s Essar Power Ltd. at their cost.

Members may like to note.

During 49th meeting of Commercial Committee, the constituents expressed

concerned about delay in commissioning/commercial operation of generating unit

at Sipat STPP by NTPC as the associated transmission system has been

commissioned and the beneficiaries are not getting the benefit of generation from

Sipat STPP. In this context it was pointed out that the commissioning of

transmission elements associated with the above project have strengthened the

grid and benefited the Western Regional Grid as a whole.
