AGENDA NOTES FOR 10th MEETING OF WESTERN REGIONAL POWER COMMITTEE TO

BE HELD ON 30TH MAY 2009 AT DIU

ITEMS FOR DISCUSSIONS

ITEM No.1: CONFIRMATION OF THE MINUTES OF THE 9th MEETING OF WRP

COMMITTEE Minutes of 9th meeting of WRP Committee held on 9th January 2009 at Lonavala

were sent to the members vide letter No. WRPC/Minutes/AS/2008-09-1218 dated 3rd

Feb. 2009.

Comments have been received from ED, MPPTCL (emclosed at Annexure-1) on

Item No. 4.5 “Transmission System for evacuation power from Krishnapattam UMPP

and requirement for additional transmission capacity between SR – WR”. MPPTCL

have proposed the following amendment in last 4 lines of Para 4.5, Page –15 :

“ WR Constituents agreed to share only 25% transmission charges” may be replaced

by “WR Constituents (except Madhya Pradesh & Chhattisgarh) agreed to share only

25% transmission charges”.

WRP Committee may like to discuss and confirm the minutes.

ITEM No. 2: LTSA ARRANGEMENT FOR SCADA/EMS UNDER WR ULDC SCHEME

2.1 In the 8th meeting of WRPC held on 12th September 2008, WRLDC had

intimated that ULDC project was under extended AMC period upto 31.05.2009 and

stressed the need for going in for a comprehensive Long term Service agreement

(LTSA). In this connection, it was informed to the Committee that M/s GE had

submitted their offer to take up AMC which broadly covered the scope of

SCADA/EMS/DTS software as well as hardware at ten control centers

commissioned under the ULDC project. The WRP Committee discussed the matter

and opined that ULDC/SCADA O&M committee may discuss and negotiate the cost

Agenda Notes of 10th meeting of WRP Committee to be held on 30th May 2009at Diu 1

with M/s GE and also examine the alternative options and the outcome of the above

meeting should be placed before WRP Committee for consideration and approval.

2.2 Based on the feedback given by WRLDC the matter was further deliberated

by the TCC in the meeting held on 15th January 2009 and further deliberated during

the 9th meeting of WRPC held on 16th January 2009. The WRP Committee agreed to

the recommendation of the TCC that (i) Negotiation Committee being nominated by

PGCIL may negotiate the cost with M/s GE to a reasonable acceptable level and

(ii) alternatively, PGCIL may go for inviting quotation etc. on limited bidding and

formulate the specification. However, while formulating the specification by

WRLDC/PGCIL, views of SLDCs may also be taken care of. The WRP Committee

felt that it would be preferable to include five years support as a part of procurement,

considering the present scenario. After discussions, it was felt that latest features

like integration of PMUs, better GUI could be specified and the replacement system

should be evergreen with the vendor providing the latest updates. It was also

agreed that WR constituents would be associated while finalizing the technical

specifications.

2.3 In this context WRLDC vide letter dated 7th May 2009 intimated the following:

(i) As per the directive of WRPC Negotiation process with GE was initiated.

Three Negotiation Committees viz., one of WR constituents, other

POWERGRID Negotiation Committee followed by Senior level

POWERGRID Negotiation Committee held comprehensive negotiations

with M/s.GE, the original equipment manufacturer (OEM) of WR

SCADA/EMS systems. The initial price quoted by M/s.GE was Rs.46.14

crores which was brought down to Rs.32.5 crores after three

negotiations.

(ii) In respect of alternative arrangement suggested by WRPC a proposal

was received from M/s. OSI, however the same has many issues like

IPR, OSI not being the OEM and absence of competitive bidding. Based

on the experience of all other RLDCs, it is felt that OEM would be the

best option.


(iii) The extended AMC is to end on 31.05.2009, it is proposed that

maintenance be got done through M/s GE, the Original Equipment

Manufacturer in light of the above, considering all the related aspects to

ensure interrupt-free operation of the SCADA/EMS functionality at all the

Control Centers in WR.

WRP Committee may discuss and finalise further course of action.

ITEM No.3: TRANSMISSION SYSTEM ASSOCIATED WITH THE TILAIYA ULTRA MEGA POWER PROJECT (4000 MW) IN JHARKHAND, NABINAGAR (1000MW) OF RAILWAYS AND NTPC, BARH-II (1320 MW), RIHAND-III (1000MW), VINDHYACHAL-IV (1000MW) AND MAUDA (1000MW) OF NTPC, AND IPPS IN JHARKHAND, ORISSA, MP, CHATTISGARH AND MAHARASHTRA

3.1 The 28th meeting of the Standing Committee on Power System Planning in

WR was held at Aurangabad on 6th December 2008. In the meeting transmission

system associated with Tilaiya Ultra Mega Power Project (4000 MW) in Jharkhand,

Nabinagar (1000 MW) of Railways and NTPC, Barh-II (1320 MW), Rihand-III (1000

MW), Vindhyachal-IV (1000 MW) and Mauda (1000 MW) of NTPC, and IPPs in

Jharkhand, Orissa, MP, Chhattisgarh, and Maharashtra were discussed and

identified. The transmission scheme were identified in four groups, viz. (i) generation

specific, (ii) system strengthening common for WR and NR, (iii) system

strengthening for WR and (iv) pooling stations for IPPs in Orissa. Also, proposal for

sharing of transmission charges had been discussed and recommended in the

above Standing Committee Meeting.

Recommendations of the Standing Committee were discussed in detail during 9th

meeting of WRP Committee held on 16th January 2009. Some of the members

expressed that the minutes of Standing Committee Meeting were received only few

days earlier and they needed time to examine the same. After discussions, it was

decided that :

(i) The constituents will furnish their comments on the minutes of

28th Standing Committee Meeting on power system planning in WR to

CEA at the earliest.


(ii) The constituents if so desire may seek any clarification from CEA and

communicate their views to them.

(iii) CEA will convey a meeting to discuss and finalize the transmission

scheme and in case, the clearance is given, by the constituents of WR to

the same, the matter will not again put up to WRPC for its approval.

3.2 Subsequent to the decision taken in 9th WRPC meeting, comments were sent

to CEA by CSEB, MPTRANSCO and MAHATRANSCO. CEA accordingly clarified

the matter in a Special Meeting of the Standing Committee on Power System

Planning of WR was held on 18th April 2009. Member (PS), CEA in the meeting

stressed that the proposal circulated in the agenda for the 9th WRPC meeting

identifying the transmission scheme etc. was basically a sort of master plan for

evacuation of power from various IPPs and other projects anticipated in the same

time frame.

Further, as desired by MAHATRANSCO in their comments, PGCIL made a

presentation indicating how the transmission charges would vary with the

commissioning of System strengthening for WR and System strengthening common

for WR and NR and its impact on pooled transmission charges. Members desired

that the details of the calculations and the assumptions made should be circulated to

the various constituents of the WR along with the calculation of corresponding

transmission charges of NR which is likely to share the capacity of the project(s).

CSEB representative suggested that only one Rourkela-Raigarh 400 kV D/c line be

LILOed at Jharsurgada instead of all the 4 circuits, as proposed in the 28th SCM. It

was explained by Member(PS), CEA that LILO of all the 4 circuits is a temporary

arrangement, and once the Jharsurgada-Dharamjaygarh-Jabalpur link is available,

LILO of one D/c will be removed at Jharsurgada.

The detailed transmission scheme as decided in the 28th meeting of the Standing

Committee on Power System Planning in WR held at Aurangabad on 6th December

2008 and subsequent modification therein suggested by PGCIL in name of pooling

station etc. during Special Meeting of the Standing Committee on Power System

Planning of WR held on 18th April 2009 is enclosed at Annexure- 3. The actual


programme with each of the projects once finalized would be brought forth in the

SCM.

The matter was discussed in detail in the Special Meeting of the Standing Committee on Power System Planning of WR held on 18th April 2009 and all the constituents agreed with the proposal. WRP Committee may kindly note the same.

ITEM No.4: TRANSMISSION SYSTEM CONNECTED WITH VINDHYACHAL POOLLING STATION AND PHASING OF TRANSMISSION WORK

During the Special meeting of Standing Committee on Power system Planning of

WR held on 18th April 2009 at WRPC office, Mumbai, CEA stated that Vindhyachal-

IV, Rihand-III and Aryan Coal were presently proposed to be connected to 765/400

kV Vindhyachal pooling station. As the generators would be coming in different time

frame, the transmission system from Vindhyachal pool onwards up to Gwalior would

need to be initially operated at 400 kV to avoid reactive power management problem.

Therefore, CEA suggested the following phasing of transmission system

interconnected from Vindhyachal pool.

(i) When the initial unit at Vindhyachal stage-III and Rihand-III generation are

commissioned they could be connected to Vindhyachal Pooling point and

the Vindyachal Pooling-Satna-Gwalior 765 kV link is charged at 400 kV

level.

(ii) In this time frame few units at Sasan would only be commissioned and

there would not be any short circuit level problems at Vindhachal 400 kV

generating bus due to LILO of Vindhyachal- Jabalpur 400 kV D/C at

Sasan.

(iii) When the entire planned generating stations connected to Vindhyachal

pooling station are commissioned, at that stage the Vindyachal Pooling-

Satna-Gwalior link can be charged at 765 kV level along with

interconnection of Sasan-Vindyhachal 765 kV S/C.

(iv) After charging at 765 kV level the LILO of Vindhyachal – Jabalpur 400 kV

D/C line at Sasan could be disconnected with suitable switching


arrangements at Sasan 400 kV switchyard to meet its starting power

requirements in future.

The above was agreed to and it was also decided that for implementation the

following works could be taken up as a separate project associated with

Vindhyachal-IV and Rihand-III.

Transmission System associated with Vindhyachal-IV and Rihand-III A. Generation Specific Transmission System

Rihand-IV (1000MW)

• Rihand-Vindyachal pooling 2xS/C 765kV lines operated at 400kV (

under preview of NTPC)

Vindhyachal-IV (1000MW)

• Vindhyachal-IV – Vindhyachal pooling 400kV quad D/C line (under

preview of NTPC)

B. System strengthening common for WR and NR

• Vindhyacal pooling station with 2x1500MVA 765/400kV (initially to be

a switching station at 400 kV level)

• Vindhyachal pooling-Satna 2XS/C 765kV lines ( initially to be

operated at 400 kV)

• Satna-Gwalior 765kV 2XS/C ( initially to be operated at 400 kV)

• Vindhyachal-Sasan 765 kV S/C

WRP Committee may like to note. ITEM NO. 5: ALLOTMENT OF TRANSMISSION CAPACITY TO IPPs AGAINST

THEIR APPLICATION FOR AVAILING LTOA 5.1 In the context of Long Term Open Access meeting held at Aurangabad in

Dec.’08, CSEB vide letter No. CSEB/MIC/WRPC/ 3254 dated 16th Dec. 2008 had

raised certain issues concerning processing of applications in respect of Long Term

Open Access (LTOA) viz. (i) there seems to be no set criteria and qualification for

selection of IPPs from the lot for granting LTOA from the margin available with

existing transmission capacity of the transmission network in service, (ii) existing


margin in the transmission capacity is to accommodate the increased power flow of

the existing beneficiaries and is utilized by them for meeting the seasonal peak

demands and (iii) the IPPs who are allotted LTOA in the existing transmission

capacity would have to pay much less than IPPs who would avail LTOA in new

transmission system. CSEB therefore desired that the issue needs to be deliberated

by WRPC.

5.2 The matter was deliberated in the TCC meeting held on 15th January 2009

and recommended as under:

(i) CTU should circulate a paper to the constituents of WR on the criteria,

procedure etc. being followed by them in processing of application for

granting of Long Term Open Access.

(ii) A meeting should be convened by PGCIL by first week of Feb. 2009 to

discuss the above issues on LTOA.

(iii) It was suggested that LTOA meeting may be separately held well

before Standing Committee meeting on Power system Planning of WR.

After detailed deliberations, the WRP Committee in its 9th meeting held on 16th Jan.

2009 decided that PGCIL would circulate a base paper on procedure for granting of

LTOA to all the beneficiaries within a week. All constitutes will give their comments to

PGCIL within a month and thereafter PGCIL will arrange a meeting to discuss the

same and formulate the guidelines. PGCIL agreed to the same.

5.3 Accordingly, General Manager (Engg), PGCIL vide letter dated 23rd Feb. 2009

circulated a base paper on procedure for granting of LTOA to all the beneficiaries.

Subsequently, in a Special Meeting of the Standing Committee on Power System

Planning of WR held on 18th April 2009, PGCIL made presentation regarding the

methodology, procedure and the payment security mechanism being adopted by

them for grant of Long Term Open Access.

5.3.1 PGCIL clarified that grant of LTOA was being done in four stages. In the first

stage discussion were held with the IPPs regarding achieving of various milestones

viz. acquisition of land, allocation of coal and water, environment clearance,

placement of orders for equipment, payment of advance to manufacturers, EPC


contractors etc., and only after some progress was noted and after observing the

progress of project take off, further discussion were held with the IPPs and grant of

LTOA was considered. In the second stage discussions with IPPs and beneficiaries

were undertaken in the SCM and LTOA meetings. The third and fourth stage was

security mechanism like Bank Guarantee from IPPs along with signing of BPTA and

6 months advance transmission charges corresponding to the capacity for which

PPA had not been signed by the IPP with beneficiary states(s). Regarding time

frame for granting LTOA, PGCIL informed that as per draft open access regulations

the nodal agency was required to dispose of the application for connectivity within 60

days and norms for medium term open access were even stringent and suggested

holding of SCM meetings every two months.

5.3.2 Member (PS), CEA clarified that as per the Electricity Act 2003 and the

existing regulation non-discriminatory open access had to be granted in case

existing margins were available. In case the existing transmission margins were not

adequate for grant of LTOA, additional transmission lines were being planned and

built. The transmission capacity was for the beneficiaries and was not allocated to

the generators. As and when the allocation from the generator would get finalized

and the beneficiary signs BPTA with the CTU then the transmission capacity would

get allocated to the beneficiary. Many of the IPPs were indicating target beneficiaries

because the distribution/transmission licensees could procure their power

requirements only through competitive bidding process and this process was not

moving fast. To facilitate IPPs, the above methodology was being adopted. In case

of Merchant Power Plants if the actual sale of power was different from the one

indicated and for which open access had been granted then as per present

regulations, in addition to long term open access charges, short term open access

charges would also be applicable. Regarding planning of transmission system CEA

further clarified that planning of transmission was being done considering various

perspective load generation scenarios during different periods of the year and

transmission was being planned considering the worst case scenario.

CEA also clarified that any transmission capacity built and not allocated to any

agency on long term basis would be allocated to other agency on medium term or

short term basis. In the event there is a delay in commissioning of any IPP, the long


term transmission capacity granted to it would be made available to any other

generator coming up in the time frame and the additional transmission required for

the delayed IPP would be built to match with its commissioning so that unutilized

transmission capacity is not built up and the Transmission companies are not

unnecessary burdened with additional transmission charges. The transmission

system would be optimal to take care of the requirement meeting the planning

criteria.

WRP Committee may like to note. ITEM No.6: PERFORMANCE OF WR GRID DURING JAN. 09 TO APR. 09 6.1 SYSTEM PERFORMANCE During the period January 2009 to April 2009, the grid operated in the frequency

range of 49.0 Hz to 50.5 Hz for 96.67% of time. The percentage time when

frequency was within this range varied between 94.15% to 98.08%. During this

period, frequency remained below 49.0 Hz for 3.20% of time. From 1st April 2009,

CERC has amended the permissible frequency range for system operation to 49.2

Hz – 50.3 Hz. During the month of April 2009, grid frequency remained in the

revised frequency band for 80.93 % time and it remained below 49.2 Hz for 18.75%

of time. The frequency profile during the period was generally satisfactory except on

a few days in February,2009 and April,2009, when drawal by NR and ER increased

due to sudden weather changes / generating unit outages. The comfortable system

performance during most of the period was due to marginal drop in unrestricted

demand as compared to last year and improved availability due to synchronization of

new generating units at Sugen, NSPCL-Bhilai, Sipat and Trombay. The details of

frequency profile during the period from January 2009 to April 2009 are furnished at

Annexure 6.1(a).

The unrestricted demand of Western Region during the period varied between

35300MW to 37400 MW. The corresponding figures for the previous year were

between 38640MW to 39800 MW. The maximum demand met during the period

was 31608 MW and the region faced capacity shortage in the range of 5300 MW to


6400 MW. The details of Unrestricted Demand vs. Demand Met and Energy

Requirement vs. Availability are furnished at Annexure.6.1 (b).

WRP Committee may like to note.

6.2 Voltage Profile 6.2.1 The month wise detail of voltages at 400 kV and 765 kV sub-stations during

the month of January,2009 to April,2009 is placed at Annexure 6.2. During the

period low voltage was observed at Karad 400 kV touching to 320 kV on 12.01.2009

and at Sipat and Seoni 765 kV voltages touched 726 & 720 respectively on few

occasions.

High voltage was recorded at 400 kV throughout the period at Dhule, Itarsi and

Karad S/s in the order of 428 kV to 438 kV. To contain high voltages WRLDC had to

resort to opening of 5 to 6 lines on many days. In order to control incidences of high

voltages during low load periods, installation of reactors at following locations has

been planned by various utilities:-

Sl.No. 400 kV Substation

Size (MVAR)

Implementing Agency

Expected Commissioning date

1. Khandwa 1x125 PGCIL June,2010 2. Dhule 2x50 MSETCL Oct.,2009 / Dec.,2009 3. Dehgam 1x125 PGCIL June,2010 4. Kasor 1x125 GETCO November,2009 5. Karad 1x80 MSETCL May,2009 6. Nardipur 1x80 GETCO October,2009

All the concerned utilities may indicate further progress made and expected date of

installation and commissioning of reactors at the above locations. They are also

requested to ensure timely commissioning of these reactors as this would help in

smoothening of high voltage profile in Western Regional Grid.

6.2.2 The issue regarding high voltage in Dhule area was discussed in the 8th & 9th

meetings of WRPC. In the 8th meeting of WRPC held on 12th September,2008,

PGCIL was requested to conduct studies for installation of reactors at Nagda or


Rajgarh. During the 9th meeting of WRPC held on 16th January,2009, it was

intimated that the study carried out by PGCIL indicated that after commissioning of

all the reactors, that are under implementation, voltage at Rajgarh, Nagda and Dhule

remain at 410, 405 & 410 kV respectively. It was therefore suggested that to contain

high voltage, efforts might be made by the respective utilities to install the bus

reactors already planned at various 400 kV sub-stations expeditiously. It was

further suggested that at the same time other means of voltage control like switching

off shunt capacitors during lean hours, setting of transformer taps etc. should also be

explored.

6.2.3 The TCC in its meeting on 15th January,2009 observed that even after taking

all other actions, including opening of a number of lines, high voltage problem was

still persisting. PGCIL was therefore requested to carry out fresh studies to examine

the requirement of bus reactor around 400 kV Nagda / Rajgarh sub-station.

6.2.4 The matter was further discussed in the special meeting of the Standing

Committee on Power System Planning in Western Region held on 18th April,2009.

In this meeting, PGCIL intimated that according to studies carried out by them,

installation of 1 X 125 MVAR bus reactor at Nagda / Rajgarh would be beneficial to

control over voltages. After examining various options, installation of 1 x 125 MVAR

bus reactor at Rajgarh sub-station was agreed to.

WRP Committee may kindly note. ITEM No.7: WIDE AREA MANAGEMENT SYSTEM OF WR WRLDC vide letter dated 7th May 2009 (enclosed at Annexure- 7) stated that the

existing SCADA / EMS provides the data which are steady state in nature and not

suitable for dynamic monitoring and control of Grid due to high degree of latency of

telemeter data and also non-synchronization of sampling of data. Emerging

technologies like Wide Area Measurement System (WAMS) using Phasor

measurement Unit (PMU) provide more advanced measurement system that will

utilize synchronized measurements from geographically distant locations and

increase the situational awareness by monitoring a wide area of power system in

real time.


In this regard WRLDC intimated that TCS has approached PGCIL to join the

consortium team of TCS, IIT Bombay and Tata Power for executing a PMU based

project which has been approved by Council of Scientific and Industrial Research

(CSIR) of Department of Science & Technology, Government of India, under the

NMITLI (New Millennium India Technology Leadership Initiative) program. CSIR will

provide Loan for the project. The main features of the project are as follows:

CENTRAL SECTOR POWER TO UT OF DD, DNH & GOA WRTS-I, PGCIL during 52nd meeting of Commercial Committee held on 9th April

2009, intimated that Service Tax Cell of Central Board of Excise and Customs have

issued summons for furnishing data regarding Service Tax recovery. PGCIL

therefore felt that collection of wheeling charges by POWERGRID for

MSETCL/MSEDCL and GETCO/GUVNL may have to be discontinued from April


2009 and the concern transmission companies viz. GETCO and MSETCL can take

up the billing/collection from April 2009.

In the CCM, it was pointed out that the decision of pooling of wheeling charges in

PGCIL bill was taken in WRE board meeting. Further, the matter regarding fixation

of and adjudication of the transmission charges of GETCO system used for

transmission of Central Sector power to DD/DNH is under consideration of Hon’ble

CERC and is scheduled for hearing shortly. As such, constituents of WR stressed

that till such time any order is given by CERC, the present methodology of billing of

transmission charges for wheeling of central sector power to DD & DNH and Goa

should be continued. This would facilitate the adjustment/recovery of any

transmission charges, as the entire record and billing details are available with

PGCIL.

WRP Committee may like to discuss. ITEM No. 9:RENOVATION AND MODERNISATION OF WRPC OFFICE BUILDING WRPC office building is around 30 years old and is in urgent need of major repairs.

THERMAL GENERATING STATION

Clause 21(4) Of Central Electricity Regulatory Commission (Terms And Conditions

Of Tariff) Regulation, 2009, which has come into force w.e.f. 1.04.2009 envisaged

that in case of fuel shortage in a thermal generating station, the generating company


might propose to deliver a higher MW during peak-load hours by saving fuel during

off-peak hours. The concerned Load Despatch Centre may then specify a pragmatic

day-ahead schedule for the generating station to optimally utilize its MW and energy

capability, in consultation with the beneficiaries. Average Declared Capacity i.e. DCi

in such an event shall be taken to be equal to the maximum peak-hour ex-power

plant MW schedule specified by the concerned Load Despatch Centre for that day.”

The matter was deliberated in 52nd meeting of Commercial Committee held on 9th

April 2009 and it was decided that the following methodology will be adopted in WR

for computation of DCi in case of fuel shortage:

(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

ITEM No. 13: SHIFTING OF SLDC BHILAI TO RAIPUR 13.1 In order to improve the data reliability from SLDCs to RLDC and vice versa,

scheme for backup communication links from SLDCs and strategic locations in the

network of ULDC scheme of WR was discussed and approved in the 7th meeting of

WRP Committee held on 3rd May 2008. During this meeting, CSEB intimated that

SLDC, Bhilai is to be shifted to Raipur and as such the corresponding expenditure

for data communication link from Raipur to Bhilai shall required to be pooled in

regional system. The WRP committee had agreed to the same.

In the above context, WRTS-I, PGCIL during 9th meeting of WRP Committee held on

16th Jan. 2009, intimated that cost estimates (about Rs. 5.16 Crores) have been

worked by them based on inputs from CSEB and requested WRP Committee for its

approval. The WRP Committee members deliberated the matter and gave in

principle approval for the same. However, it was suggested by MPPTCL that the

SCADA Committee of WR may examine the cost estimates worked out by PGCIL.


13.2 In view of above, in the meeting of Regional SCADA/Communication Co-

ordination group (RSCG) held at WRLDC, Mumbai on 12th March 09, the details of

break up of cost estimates of Rs. 5.16 Crores was examined and discussed in detail.

The SCDA/ Communication Committee found the above estimates technically

justified. However, some of the constituent states of Western Region did not agree to

pool the expenditure. CSEB insisted that the issue of sharing the above expenditure

has been agreed in WRP Committee meeting and the decision already taken should

not be reviewed. In view of this, WRLDC, PGCIL requested to discuss the matter by

the member of Commercial Committee.

13.3 The matter was discussed in the 52nd meeting of Commercial Committee. It

was stressed that this Committee cannot review the decision taken by WRP

Committee for pooling the expenditure in the regional system. Further, it was

REGION FOR THE PERIOD FROM JUNE 09 TO AUG. 09.

The anticipated power supply position in the region for the period from June,2009 to August,2009 is furnished at Annexure-17 for information of the members. The period under consideration is monsoon season and the regional demand is likely to


be low as compared to summer period. Aggregate unrestricted demand will vary from 33284 MW to 35249 MW and deficit will vary from 0.21% to 11.40%. In terms of energy, the unrestricted requirement is varying from 20769 MUs to 21375 MUs with regional deficit varying from 7.59% to 16.31%. The anticipated Peak demand shortages for Gujarat, Chhattisgarh, Maharashtra, Goa,DD and DNH is 910 to 1989 MW,223 to 396 MW,2816 to 3940 MW, 84 to 122 MW, 29 to 45 MW and 34 to 127 MW respectively.

Although deficit is comparatively less than other peak period due to monsoon season, Constituent states will have to be vigilant as regards to frequent tripping of lines and high voltages in certain pockets. Also, maintenance programme of generating units will have to be planned after taking into consideration regional demand and also diversity in demand of NR and ER in an integrated combined N-E-W grid.

Agenda Item given by WRLDC vide letter dated 7th May 2009 WIDE AREA MANAGEMENT SYSTEM OF WR

Indian Grid is expanding exponentially with increased number of interconnections between Regions. There are further requirements imposed by Regulatory Regime, deregulated energy market & consumer aspiration for quality and reliable power supply. All these requirements with increasing complexity of Grid Operation manifold necessitates dynamic monitoring of parameters /conditions on real time basis.

The existing SCADA / EMS provides the data which are steady state in nature and not suitable for dynamic monitoring and control of Grid due to high degree of latency of telemetered data and also non-synchronization of sampling of data. Emerging technologies like Wide Area Measurement System (WAMS) using Phasor measurement Unit (PMU) provide more advanced measurement system that will utilize synchronized measurements from geographically distant locations and increase the situational awareness by monitoring a wide area of power system in real time. Technologies which are under various stages of development based upon WAMS facilitate real time visualization of power systems, real time congestion management, design of an advanced warning system, validation and fine tuning of system models and design of an adaptive protection system. Worldwide various utilities have started using / developing this new technology and pioneer utilities are from North America, Europe, China, Russia and Brazil etc.

It may be appreciated that the complexities of Indian Grids are as vast as in any other country. However, in India so far this technology has only been at the discussion / planning stage and taking into consideration the importance of the issue, it is necessary that the different transmission utilities take expeditious action in the matter. These technologies have been envisaged in the GoI report of Working Group on Pow4er for 11th Plan as well as National Electricity Plan – Transmission, wherein it is advised to take up Pilot Projects.

2

In this regard TCS has approached POWERGRID to join the consortium team of TCS, IIT Bombay and Tata Power for executing a PMU based project which has been approved by Council of Scientific and Industrial Research (CSIR) of Department of Science & Technology, Government of India. Under the NMITLI (New Millennium India Technology Leadership Initiative) program. CSIR will provide Loan for the project. The main features of the project are as follows:

• Installation of PMUs (Phasor Measurement Units) at around 25 to 30 locations in Western Region Grid. The data from PMUs shall be acquired at Western Regional Load Despatch Centre (WRLDC).

• Development of software functions using PMU data.

POWERGRID share of total estimated cost of the project

is Rs. 8.76 crores. The loan from CSIR is to be repaid over 10 years at an interest rate of 3% after completion of the project. The annual installments shall be ranging from Rs. 90.267 lakhs to Rs. 127.01 lakhs.

It may be mentioned that al Pilot Project for implementation of PMUs in Northern Region has been agreed upon in the last NRPC meeting held on 22.04.2009

The project can be funded through UI CAP fund or Additional UI funds. Alternatively the constituent may finance the project and make yearly advance payment to POWERGRID.

The Committee may discuss and finalized the funding of the WAMS project in WR.
