MINUTES OF 10th MEETING OF WESTERN REGIONAL POWER COMMITTEE HELD ON 30TH MAY 2009 AT DIU

The TCC and 10th WRP Committee meetings were held on 29th & 30th May 2009

respectively at Diu. The lists of the participants are at Annexure-I (A) & I (B)

respectively.

Shri P. Patel, Member Secretary, WRPC welcomed the Members and participants to

the 10th meeting of Western Regional Power Committee. He intimated that Shri S.

Jagadeesan, Chairman, WRPC/GSECL and Principal Secretary (Energy), Govt. of

Gujarat could not attend the meeting and as desired by him, the meeting is being

chaired by Shri G. Mohapatra, Chairman, Uttar Gujarat Vij Co. Ltd.

Shri P. K. Gupta, Secretary (Power), UT of Daman & Diu and Dadra & Nagar Haveli

welcomed the Members and participants to the 10th meeting of Western Regional

Power Committee at small beautiful island of Diu. He stated that UTs of Daman &

Diu and Dadra & Nagar Haveli were under Portuguese regime and were liberated in

the year 1961. He further stated that after formation of State of Goa in the year 1987

UT of Daman & Diu was formed. Diu district remained vital sea port & naval base for

considerable strategic importance from 14th Century onwards and has a colorful

culture and mix of gujarathi and Portuguese tradition & custom in its spectrum of life

and art. He further stated that around the year 1987-88 govt. of India declared tax

holidays of 15 years for local taxes, excise & income tax loading to rapid

industrialization of territories of Daman and Diu and Dadra & Nagar Haveli. Power

demands of these UTs have grown very fast thereafter. He further stated that

demand met for DD & DNH is around 230 MW and 450 MW respectively but the

actual demand is much higher resulting in huge shortage of power. He requested

all the members to help these UTs in meeting their growing power demand.

Shri G. Mohapatra, Chairman, UGVCL welcomed members and participants of the

10th WRPC meeting. He briefly reviewed the performance of Western Regional grid

during the period from January 2009 to April 2009. He stated that from 1st April 2009,

CERC has amended the permissible frequency range for system operation to

Minutes of 10th meeting of WRP Committee held on 30th May 2009 at Diu 1

49.2 Hz – 50.3 Hz. He observed that 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

He informed that during the period January 2009 to April 2009, total 1182.5 MW

capacity were added in WR grid which comprise of 250 MW Trombay TPP in

Maharashtra, 382.5 MW by Torrent PGL in Gujarat, 300 MW, Lanco in Chhattisgarh

and second 250 MW by NSPCL in Chhattisgarh. He further informed that 400 kV

D/c Zerda-Kankroli line associated with N-W transmission corridor strengthening

scheme has been commissioned and certainly enhanced the inter-regional capacity

between WR & NR. He thanked the administration of UTs of Daman and Diu and

Dadra & Nagar Haveli for willingly hosting the WRPC meeting at Diu and making

excellent arrangements for the same. He then requested Shri P. Patel, Member

Secretary, WRPC to take up the agenda items.

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

COMMITTEE 1.1 Member Secretary, WRPC stated that the 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.

He stated that comments have been received from ED, MPPTCL vide letter dated

17th Feb. 2009 on Item No. 4.5 “Transmission System for evacuation of 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”.


1.2 The WRP Committee discussed the matter and the following amendment in

last line of 4.5, Page –15 of 9th Minutes of WRPC meeting was agreed:

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

replaced by “WR Constituents (except Madhya Pradesh & Chhattisgarh)

agreed to share only 25% transmission charges. The cost component that

corresponds to Madhya Pradesh and Chhattisgarh will also be borne by

Maharashtra.”

WRP Committee confirmed the minutes of 9th WRPC meeting with the above modification.

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

2.1 Member Secretary, WRPC stated that 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 with M/s GE and also examine the alternative

options and the outcome 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 etc. 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 rounds of

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.

2.4 Member Secretary, WRPC further stated that the above matter was discussed

in the TCC meeting held on 29th May 2009 and the various constituents expressed

their views.


Executive Director, WRLDC informed the TCC about the action taken by the SCADA

O&M Committee and WRLDC / PGCIL regarding LTSA arrangement for SCADA /

EMS under ULDC of WR. He stated that after two negotiations with M/s. GE, the

original equipment manufacturer (OEM), followed by third at Senior level PGCIL

Negotiation Committee constituted by Chairman, PGCIL the initial price of Rs. 46.14

Crores quoted has been brought down to Rs.32.5 Crores for 5 years maintenance.

He stated that with the stringent regulations from CERC, the RLDCs / SCDCs can

not afford to have any interruption in the process of monitoring the power system

through SCADA / EMS. This ULDC SCADA / EMS project is very complex and

having application software which is proprietary in nature and cannot be maintained

by other vendor. The third party cannot maintain the system unless they replace the

existing system. Further the kind of exposure and manpower we have, it will not be

possible to maintain the ULDC equipment by RLDC and SLDCs. In PGCIL the issue

has been seriously thought of and it has been opined that this maintenance should

be got done through OEM route. Also, this particular activity has been outsourced in

all other regions to OEM. The cost after negotiation has substantially come down

and accordingly the monthly charges will be of the order of about Rs. 5 to 8 Lakhs

per month per centre. Further, considering the distinct advantage of going through

OEM route and the kind of application we are spending for, the negotiated cost is

justified. He earnestly requested the TCC members to consider this favourably.

General Manager I/c (LD &C), PGCIL stated that the life expectancy of SCADA/EMS

system is about 7 years and the system becomes obsolete not totally but in terms of

software and the technological development and new addition that are going on. In

WR the SCADA / EMS system was commissioned in Feb. 2006 and as its cost-

recovery has not been fully made, replacement of the existing system cannot be

thought of at this stage. He further stated that PGCIL is now in process of planning

back up and up-gradation of Control Centres at RLDC as well as at SLDCs. The

future systems will be equipped with latest up to date technology available in the

market at the time of replacement / up gradation. So far as LTSA is concerned, he

stressed that there are always advantages of going through OEM route in this field

as it is highly technical area and the OEM has all historical data base besides issues

like IPR, source code protection etc. He added that other regions have also gone for

maintenance of their system through OEM route only. He further stated that the cost


per control centre of WR with the negotiated price Rs. 32.5 Crs for 5 years works out

lower than the cost paid in SR. He felt that above negotiated price is reasonable and

the maintenance of WR SCADA/EMS can be entrusted to M/s GE. He assured that

PGCIL would make efforts to ensure that pending issues, if any, besides training etc.

will be looked into.

OSD, MPPTCL stated that though in their view the negotiated cost of Rs. 32.5

Crores is not reasonable, we do not have any alternative other than going to OEM.

He stated that earlier WRLDC had given the impression that third party can maintain

the system. Executive Director, WRLDC stated that earlier in WRP Committee

meeting held at Jabalpur, WRLDC told the Committee that maintenance of SCADA /

EMS is of proprietary nature and the third agency cannot maintain the application

software. However, as per the directions of WRP Committee, the SCADA O&M

Committee of WR looked into the matter and the progress was reported to the WRP

Committee.

Chhattisgarh State Power Transmission Co. Ltd. representative stated that even

though the WRP Committee was considering the maintenance through OEM route,

they advised to explore the alternate route so as to put pressure on bringing down

the cost offered by M/s GE. He felt that this has been done and the negotiated price

of Rs. 32.5 Crores is reasonable and may be accepted.

Chief Engineer (LD), MSETCL also felt that the price has now come down but still it

is felt that the same is more. He further stated that after 3-5 years we may have to go

for new system. He suggested that we may go for maintenance with M/s GE for

three years instead of 5 years and look for other alternative system within this period.

He opined that we should go for OEM route with exit option after 3 years as 2-3

years time will be required for establishment of new system. In this context, ED,

WRLDC stated that we could exit from the contract after 3 years, however, about

10% extra cost of the balance period will be required to be paid.

Chief Engineer (LD), GETCO stated that today we have not any alternative other

than OEM. He enquired whether any up-gradation of the existing system will be

possible during LTSA period. In this context, ED, WRLDC stated that this issue was


discussed during the SCADA O&M committee meeting and M/s GE said that any up-

gradation would have to be done at extra cost. MD, Chhattisgarh State Power Transmission Co. Ltd., who chaired the TCC meeting

said that the TCC may recommend for LTSA through OEM route and the action for

going for alternate new system should be started two years earlier before expiry of

contract. After detailed deliberation, the TCC recommended the following:

(i) Real time Data availability is of utmost importance for grid operation,

for which interrupt free maintenance of LD equipment has to be

ensured.

(ii) In view of the above, it is preferable to assign the maintenance of

sophisticated load dispatch system to OEM.

(iii) So far as the alternative proposal of M/s. OSI is concerned, the same

has many issues like IPR, proprietary rights concerning the source

code, legal problems, etc. Awarding of contract on single bid to the

OSI will have its own problems and going for open tenders at this

stage will end up in non-availability of any maintenance service to the

existing SCADA facilities for a considerable period.

(iv) TCC recommended that LTSA be taken up with M/s GE for five years

at about Rs. 32.5 crores. Further action may be initiated in advance

i.e. in the 3rd year itself for alternative scheme.

2.5 The matter was further deliberated in the WRPC meeting. Director (O),

MSETCL said that the OSI had made earlier presentation and offering the good

system at very competitive rates. He also opined that there is still scope for further

negotiation with M/s GE.

Executive Director (F), GUVNL stated that during last meeting, WRLDC was

requested to go for alternative option also, prepare new specification, go for bidding


for entirely new system. Further, the issue of IPR would have been arisen, if the

existing system is offered for maintenance to third party. It was also suggested that

while making specifications, provisions should be made for 10 years AMC. He

enquired the action taken in this regard.

2.6 Executive Director, WRLDC explained the background of the efforts taken to

finalize LTSA arrangements for SCADA / EMS system in Western Region. While

stating the actions taken in regard to the directions of WRPC in their 9th meeting for

exploring the alternative options, he emphasized the need for adopting OEM route

for ensuring interrupt-free availability of SCADA / EMS system for real time

monitoring and control of Western Region. He explained the difficulties likely to be

encountered in the gap period i.e. the period of commissioning of the replacement

system if the alternative option is adopted. In the light of this he strongly advocated

that WR constituents should unitedly opt for OEM route as the finally negotiated

price of Rs.32.5 Crores for five years i.e. Rs.6.5 Crores per year is comparable to the

LTSA arrangements tied up in Southern Region with the same OEM.

2.7 General Manager (LD & C), PGCIL stated that the present ULDC scheme in

WR is relatively new, just commissioned about three years ago and as such this is

not the right time to discard the same. He informed that the Pradhan Committee

report recommends that the RLDC / SLDC SCADA scheme have to be replaced and

re-looked after 7 years of service. He suggested that right now, the present ULDC

SCADA / EMS scheme of WR be continued and maintained through OEM and after

3 years or so, replacement of it could be thought of. He added that replacement of

the existing system with new system is not an easy task as lot of activities such as

operation of new system in parallel with the existing one; its evaluation etc. will go

into it.

Director, ESSAR Power Ltd. stated that new system should not be introduced for the

sake of changing the system. Studies may be carried out and whatever up-gradation

is possible may be done. While going for the new system, it may be ensured that the

vendor will be responsible for up-gradation/maintenance, which is required in future

also as the life of the equipment is around 10 years plus. He opined that LTSA may


be done through OEM who will take responsibility if something goes wrong

tomorrow. He further observed that the price has been negotiated to the best value.

2.8 Director (O), PGCIL also highlighted the need and advantages of OEM route

and stated that there is no need for replacement as the existing system is

commissioned only in February, 2006 and the capability of the systems are required

to be fully explored. Further, the existing system should be continued till there is a

major technological change like integration of PMUs etc. takes place and available in

the market. He further stated that in future we need a dynamic & intelligent system

as compared to passive system what we have today as many actions in real time

have to be done automatically due to complexity of the grid. He added that PGCIL

has already initiated action in this area. He desired that the maintenance of

SCADA/EMS of ULDC of WR may be awarded for five years to OEM with a provision

of coming out of it after three years.

Director (O), MSETCL suggested that one more round of meeting may be held with

M/s GE, wherein MD, GETCO and CMD, MPPTCL should also be requested to

participate. Date of this meeting could be fixed in consultation with them.

2.9 The matter was deliberated in detail. The WRP Committee agreed for LTSA through OEM route and decided that senior level officers of WR constituents would also interact with M/s GE for further negotiation, if any. It was tentatively proposed to have the meeting of WR constituents with M/s GE on 9th June, 2009 and Member Secretary, WRPC would coordinate the same. It was also agreed that after the negotiation with M/s GE at the senior level, WRLDC/PGCIL would go ahead with awarding of maintenance of SCADA/EMS system in Western Region to M/s GE and LTSA arrangements with them. The WR constituents further opined that replacement action for the new system should be initiated before the end of three year period so that the new system could be in place by the end of the LTSA period. PGCIL agreed to take necessary action in this matter.

(Action: WRPC/WRLDC)


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 Member Secretary, WRPC stated that in 28th meeting of the Standing

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

2008, the 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. Further, the

recommendations of the above Standing Committee were discussed in detail during

9th meeting of WRP Committee held on 16th January 2009 wherein 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

in the 9th WRP Committee meeting, 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 Member Secretary, WRPC informed that subsequently, comments were sent

to CEA by Chhattisgarh, MPPTCL and MSETCL. CEA accordingly clarified the

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


of WR 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. Also, as

desired by MSETCL in their comments, PGCIL made a presentation in the above

Special Standing Committee meeting, highlighting 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). CSPTCL 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. Member (PS), CEA explained 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.

3.3 Member Secretary, WRPC stated that 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. He added that 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.

3.4 In the TCC meeting held on 29th May 2009, representative of Chhattisgarh

State Power Transmission Co. Ltd. (CSPTCL) stated that in the Special Meeting of

the Standing Committee on Power System Planning of WR held on 18th April 2009,

CEA stated that the above transmission scheme is a master plan for evacuation of

power from various IPPs and other projects anticipated in the same time frame. The


actual programme with each of the projects, once finalized, will brought forth in the

Standing Committee meeting.

3.5 In the TCC meeting held on 29th May 2009, the members agreed to the scheme and stressed that the actual programme with each of the projects, once finalized, will be brought forth in the Standing Committee meeting and to WRPC meeting. Also, any change in the transmission scheme, if any, subsequent to discussion in other region, will have to be brought to the notice of WRP Committee for its approval. It was also stressed that as discussed in the Special SCM, held on 18th April 2009, the details of cost of transmission scheme should be sent to all the constituents by PGCIL. 3.6 WRP Committee discussed the matter and endorsed the views of the TCC. PGCIL representative stated that the details of the transmission cost will be furnished to all the concerned by 5th June 2009.

(Action: PGCIL)

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

4.1 Member Secretary, WRPC stated that during the Special meeting of Standing

Committee on Power system Planning of WR held on 18th April 2009 at WRPC

office, Mumbai, it was intimated 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-IV and Rihand-III generation are

commissioned they could be connected to Vindhyachal Pooling point and

the Vindyachal Pooling-Satna-Gwalior 765 kV link be 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 in the Special meeting of Standing Committee 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-III (1000MW)

4.2 Member Secretary, WRPC stated that in the TCC meeting held on 29th May

2009, NTPC requested that the transmission scheme from the generator to the

nearest pooling point may be taken up by PGCIL. In this context, it was pointed out


that as per the minutes of Standing Committee on Power system Planning of WR

held on 18th April 2009, the lines mentioned under generation specific system are

under NTPC purview. PGCIL, however, stated that they could take up the job on

deposit basis.

4.3 General Manager (Comml.), NTPC stated that allocation of power from

Vindhyachal-IV (1000 MW) will be done to the various beneficiaries of WR by the

MoP and as such for Vindhyachal IV – Vindhyachal pooling 400 kV D/c line should

be pooled in the regional transmission scheme. GUVNL representative enquired

whether the full generation of Vindhyachal –IV will be allocated to WR beneficiaries.

NTPC stated that allocation will be made by the Ministry of Power. It was also

clarified by NTPC that Rihand-III is for Northern Region and as such charges for the

line from Rihand-III to Vindhyachal pooling will be borne by NR beneficiaries.

4.4 WRP Committee deliberated the matter in detail and agreed to the transmission scheme as proposed in the para 4.1 above. So far as sharing of transmission charges for Vindhyachal IV – Vindhyachal pooling line was concerned, the WRP Committee requested NTPC to discuss the matter again in the Standing Committee on Power System Planning of WR and thereafter may be taken up in TCC and WRPC for further discussion. NTPC agreed to the same.

(Action: NTPC) ITEM NO. 5: ALLOTMENT OF TRANSMISSION CAPACITY TO IPPs AGAINST

THEIR APPLICATION FOR AVAILING LTOA 5.1 Member Secretary, WRPC stated that various issues raised by the

constituents concerning granting of Long Term Open Access were deliberated in the

last meeting of TCC held on 15th Jan. 2009 and in the 9th meeting of WRPC held on

16th January 2009, and it was recommended that:

(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 also suggested that LTOA meeting may be separately held well

before Standing Committee meeting on Power system Planning of WR.

5.2 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 the 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 In the above Special meeting, 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 Standing Committee Meetings every two months.

In the special SCM, it was also clarified by Member (PS), CEA that as per the

Electricity Act 2003 and the existing regulations, 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 took time. 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 further 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.

5.4 Representative of CSPTCL stated that transmission system over loading

problems have been experienced in their system after injection of generation by

LANCO-Amarkantak station, which has been granted LTOA. He requested that

LTOA to various IPPs from the existing transmission capacity should not be granted

till Hon’ble CERC issues new regulations concerning to LTOA etc.

In the above context, representative of PGCIL stated that they have granted LTOA

after consultation with all the constituents and CEA in accordance with existing

CERC regulation. Further, till Hon’ble CERC issues the new regulations, LTOA

applications received by them have to be processed on the basis of existing

regulations only.


5.5 ED (L & RA), M.P. Trading Co. Ltd. stated that MP Tradco has entered a long

term power purchase agreement with M/s PTC India Ltd. for availing entire power

generated by Unit No. 1 (300 MW) of LANCO-Amarkantak TPS. However, M/s

LANCO-Amarkantak Pvt. Ltd., issued notice vide letter dated 13.03.2008 for

termination of PPA which has been stayed by Hon’ble High Court of M.P. vide order

dated 31.3.2008. As the matter is sub-judice, M.P. Tradco requested that M/s

LANCO should not be granted either long term or short term open access for supply

of power to any utility other than Madhya Pradesh. He requested the WRP

Committee to accordingly address the issue and take a decision in the matter.

In this context, Member Secretary, WRPC stated that responsibility of granting long

term or short term open access, as the case may be, vests with CTU / RLDC as per

the provisions under the CERC regulations and WRP Committee is not empowered

to give any directions in the matter.

Director (O), PGCIL while endorsing the views of Member Secretary, WRPC, stated

that, as the matter is sub-judice, it should not be discussed. The request of M.P.

Tradeco not to grant either long term or short term open access to LANCO-

Amarkantak for supply of power to any utility other than Madhya Pradesh is a legal

issue and have to be addressed accordingly.

5.6 During the TCC meeting held on 29th May 2009, the members stressed that

the details regarding the status of LTOA applications granted by PGCIL should be

made available on their web site. PGCIL was accordingly requested to do the

needful, which was agreed to by PGCIL.

The WRP Committee members noted as above.

(Action: PGCIL) ITEM No.6: PERFORMANCE OF WR GRID DURING JAN. 09 TO MAY 09 6.1 SYSTEM PERFORMANCE Member Secretary, WRPC stated that during the period January 2009 to March

2009, the grid operated in the frequency range of 49.0 Hz to 50.5 Hz for 98.51% of


time. The percentage time when frequency was within this range varied between

97.79 % to 99.66 %. During this period, frequency remained below 49.0 Hz for 2.43

% 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 months of April and

May 2009, grid frequency remained in the revised frequency band for 80.93 % and

91.21 % respectively time and it remained below 49.2 Hz for 18.75 % and 6.45 % of

time respectively . 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

May 2009 are furnished at Annexure 6.1(a).

The unrestricted demand of Western Region during the period varied between 35700

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

36600 MW 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).

During the discussions in the TCC and WRPC meetings, ED, WRLDC pointed out

that though the frequency regime during the period was generally satisfactory, on

some days frequency was quite low. During the month of April 2009, system

frequency touched 48.8 Hz for more than 300 times. However, operation of under

frequency relays installed under AUFLS Scheme was found to be inadequate .He

stated that UF relays are required to be kept in service to act as defense mechanism

against any unforeseen incidents. He requested the constituents to ensure

healthiness of UF relays and to keep them in readiness to provide desire load relief.

WRP Committee endorsed the above


6.2 Voltage Profile 6.2.1 Committee noted the month wise details of voltages at 400 kV & 765 kV sub-

stations during the month of January, 2009 to May, 2009 is placed at Annexure-6.2.

6.2.2 During the period low voltage was observed at Sipat and Seoni 765 kV sub-

stations which touched 726 kV & 720 kV 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 415 kV to 440 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

Constituents were also requested to ensure timely commissioning of these reactors

as this would help in smoothening of high voltage profile in Western Regional Grid.

MS, WRPC informed that the issue regarding high voltage in Dhule area was

discussed in the 9th meeting of WRPC held on 16th January, 2009. It was pointed

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.

He further informed that the matter was also 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 in the standing

committee meeting.

WRP committee discussed the matter and concurred with the proposal. ITEM No.7: WIDE AREA MANAGEMENT SYSTEM OF WR

7.1 Member Secretary, WRPC stated that WRLDC vide letter dated 7th May 2009

intimated 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:

(i) 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)

(ii) Development of software functions using PMU data.

WRLDC further intimated that the PGCIL 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. WRLDC further informed that a Pilot


Project for implementation of PMUs in Northern Region has been agreed upon in

Northern Region during the last NRPC meeting held on 22.04.2009. WRLDC have

proposed that the PMU project in respect of Western Region could be funded

through UI CAP fund or Additional UI funds. Alternatively the constituent may finance

the project and make yearly advance payment to PGCIL.

7.2 In the TCC meeting held on 29th May 2009, GM I/C (LD & C), PGCIL made

detailed presentation on CSIR approved project under their NMITLI (New Millennium

India Technology Leadership Initiative) programme namely “Intelligent monitoring &

Control of the interconnected Power Grid using Wide Area Measurements (WAM)”. A

copy of the presentation is enclosed at Annexure- 7.2. The presentation was well

received and appreciated by the constituent members. However, as this project is of

high/new technology area, the TCC recommended that the technical details etc. of

the project may be discussed in a meeting of all the constituents of WR at working

level and thereafter the matter should be put up to TCC/ WRPC for further direction.

7.3 During the RPC meeting, Director (O), MSETCL stated that in Maharashtra

they had already commenced the work relating to Wide Area Measurement in

collaboration with CPRI and IIT, Kanpur after discussing the same with CEA and

MoP. At such a juncture, parallelly doing the same in WR is not desirable. In

Maharashtra they are quite serious about this project, which is highly technical and

first of this nature. He desired that let this project be implemented in small system

and then can be thought at region as whole. Further, in PGCIL proposal what

activities are going to carried out under the proposed cost of Rs. 8.76 crores is not

clear.

Director (O), PGCIL stated that taking up the above project at Regional level is not a

duplication of work. It is a development work, which is complex in nature. Executive

Director, WRLDC stated that for Regional Grid like WR, which is very large,

technically getting exposed to WAM technology is the need of the day. The

integration of heterogeneous PMU of Maharashtra with matching protocol with rest of

regional system will certainly needs expertise and experience. He requested that this

matter could be discussed separately to understand the WAM technology etc.


7.4 The matter was deliberated in detailed and the WRP Committee endorsed the

decision of TCC. It was decided that technical details of the project may be

discussed in the Regional Protection Committee meeting and hereafter the matter

will be put up to TCC / WRPC for further direction.

ITEM No. 8: BILLING OF TRANSMISSION CHARGES FOR WHEELING OF

CENTRAL SECTOR POWER TO UT OF DD, DNH & GOA 8.1 Member Secretary, WRPC stated that 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 should take up the billing/collection from April 2009. During

the above meeting of Commercial Committee, 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 was

under consideration of Hon’ble CERC and was 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.

8.2 The above matter was discussed in the TCC meeting held on 29th May 2009

and TCC agreed to the views of CCM i.e. till such time any order is given by the

Hon’ble CERC in respect of determination of transmission charges for GETCO

system for wheeling of Central Sector power to DD & DNH, the present methodology

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

and Goa through PGCIL should be continued. This would facilitate the

adjustment/recovery of any transmission charges, as the entire record and billing

details are available with PGCIL. Thereafter the billing of the transmission charge for


wheeling of central sector power should be done by GETCO / MSETCL directly, as

per REA issued by WRPC.

WRP Committee endorsed the decision of TCC. ITEM No. 9: RENOVATION AND MODERNISATION OF WRPC OFFICE

BUILDING Member Secretary, WRPC informed the Committee that WRPC office building is

around 30 years old and is in urgent need of major repairs. The building also needs

architectural renovation and improvement in facilities such as conference Hall, guest

house etc. He further informed that according to preliminary assessment the

complete R&M of the building is estimated to cost about 4 crores. However, the

actual estimate will have to be prepared by the executing agency. He proposed that

the cost of R&M be shared by the members of WRPC who are sharing the

establishment expenditure of WRPC Secretariat. Also agency for carrying out these

works needs to be decided.

Member ( GO& D) , CEA stated that Powergrid have sometime back renovated the

WRLDC building which is adjacent to WRPC. He, therefore, proposed that R & M of

WRPC could also be carried out by Powergrid so that the similarity of the two

buildings can be maintained.

WRP Committee discussed the matter and agreed that the R & M of WRPC building

could be carried out by Powergrid on deposit basis. Cost of R & M shall be equally

shared by the members of WRPC who are bearing the establishment expenditure of

WRPC Secretariat. WRP Committee also authorized the Chairman, WRPC to

approve the estimate submitted by Powergrid.

ITEM No. 10: PAYMENT OF TRANSMISSION CHARGES FOR INTER-STATE

TRANSMISSION Member Secretary, WRPC informed that in accordance with Central Electricity

Regulatory Commission (Terms & Condition of Tariff) Regulation, 2009, the monthly

Energy account (REA) issued by RPC shall also include a statement specifying the


ratio in which transmission charges for interstate transmission system for that month

are to be shared by transmission users in accordance with regulation 3.3. Also, the

bill for transmission charges (inclusive of incentive) for transmission charges for a

month should be raised by the transmission licensee based on its estimate of

Transmission System Availability Factor (TAFM) for the month and adjustment, if

any, has to be made on the basis of TAFM to be certified by the Member Secretary

of WRPC within 30 days from the last day of the relevant month.

This matter was discussed in 52nd meeting of Commercial Committee held on 9th

April 2009 and it was proposed that PGCIL would make available the details of

outages (certified by WRLDC) to all the beneficiaries by 10th of the following month.

Concerned beneficiaries, after examining these details, should furnish their

comments / observations, if any, to WRPC by the 20th of the month. For example,

outage details for the month of April 2009 will be made available by PGCIL to

beneficiaries by 10th of May 2009. Comments of beneficiaries should be furnished to

WRPC 20th May 2009. In case of non-receipt of the same by this time period, it will

be taken, as no comments. Member Secretary, WRPC, will certify the TAFM

accordingly. All the members agreed to the same.

WRP Committee noted as above. ITEM No.11: COMPUTATION OF PAYMENT OF CAPACITY CHARGES FOR

THERMAL GENERATING STATION

Member Secretary, WRPC informed that 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.”


Member Secretary, WRPC further stated that 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

WRP Committee noted the same. ITEM No.12 : IMPLEMENTATION OF REVISED UI CHARGES W.E.F. 01.04.09 Member Secretary, WRPC informed that Central Electricity Regulatory Commission

(Unscheduled Interchange charges and related matters) Regulation, 2009 has been

notified by the Commission vide Notification No.L-1(1)/2009-CERC dated 30th March

2009. These regulations have come into force on 01.04.2009. Clause 7 of the above

regulation “Limit on UI volume and consequences of crossing limits envisages the

following:

(a) The over-drawal of electricity from the schedule by any beneficiary or a buyer

during a time-block shall not exceed 12% of its scheduled drawal or 150 MW (whichever is lower) when frequency is below 49.5 Hz, and 3% on a daily aggregate basis.

(b) The under-injection of electricity from the schedule by a generating station or by a seller during a time-block shall not exceed 12% of the scheduled injection of such generating station or seller when frequency is below 49.5 Hz, and 3% on daily aggregate basis.


(c) In addition to UI Rate corresponding to frequency of 49.2 Hz, as stipulated under regulation 5, an Additional Unscheduled Interchange Charge at the rate equivalent to 40% of the UI Rate corresponding to frequency of 49.2 Hz shall be applicable for over-drawal or under-injection of electricity for each time-block when grid frequency is below 49.2 Hz. Provided that for under-injection of electricity during the time-block when grid frequency is below 49.2 Hz for the generating stations using coal or lignite or gas supplied under Administered Price Mechanism (APM) as the fuel, Additional Unscheduled Interchange Charge shall be equivalent to 40% of the UI Cap Rate.

(d) Payment of Unscheduled Interchange Charges under regulation 5 and the Additional Unscheduled Interchange Charge under (c) above, shall be without prejudice to any action that may be considered appropriate under section 142 and section 149 of the Act for contravention of the over-drawal and under-generation limit specified in these regulations, for a time block when frequency is below 49.5 Hz.

(e) The Commission may from time to time, if considered necessary, prescribe the Additional Unscheduled Interchange Charge for over-drawal or under-injection of electricity during the time-block when grid frequency is below 49.5 Hz and up to 49.2 Hz.

(f) Any over-drawal and under-injection of electricity shall be computed in

accordance with the methodology used for preparation of ‘Regional Energy Accounts’.

(g) Provided that the Regional Load Despatch Centre shall prepare and publish on its website the records, on monthly basis, of the UI Accounts, specifying the quantum of over-drawal/under-generation and corresponding amount of UI paid/received for each beneficiary or buyer and generating station or seller for the time-blocks when grid frequency was below 49.2 Hz and between 49.5-49.2 Hz separately.

Further, UI rate in a time block (15 minute) will be capped at 408 paise per kWh for

all generating stations using coal or lignite or gas supplied under Administered Price

Mechanism (APM) as fuel in case when actual generation is higher or lower than the

scheduled generation in the frequency range between 50.3 Hz and upto 49.2 Hz.


In view of the above, the procedure to be followed w.e.f. 1st April 2009 for

preparation of UI charges was discussed in 52nd meeting of Commercial Committee

held on 9th April 2009 and agreed.

So far as Application of fund collected through UI is concerned, Clause 11 of Central

Electricity Regulatory Commission (Unscheduled Interchange charges and related

matters) Regulation, 2009 envisages that the amount left after final settlement of

claims of Unscheduled Interchange charges of the generating station and the

beneficiaries shall be utilised, with the prior approval of the Commission, for either or

both of the activities viz. (a) Servicing of investment for transmission schemes of

strategic importance and (b) Providing ancillary services including but not limited to

‘load generation balancing’ during low grid frequency as identified by the Regional

Load Despatch Centre, in accordance with the procedure prepared by it, to ensure

grid security and safety. However, the amount of fund, allocable for the above

purposes shall be decided by the Commission from time to time.

WRP Committee noted the same.

ITEM No. 13: SHIFTING OF SLDC BHILAI TO RAIPUR 13.1 Member Secretary, WRPC stated that 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. Subsequently, during 9th meeting of WRP Committee held on

16th Jan. 2009 WRTS-I, PGCIL 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 Member Secretary, WRPC informed that 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 reiterated that the WRP Committee gave the

mandate to the SCADA Committee to the extent of examination of the cost estimate.

13.4 In the TCC meeting held on 29th May 2009, Chief Engineer (SLDC), GETCO

pointed out that the proposed work of Chhattisgarh including wideband equipment at

400 kV Bhilai to Urla S/s, 400 kV Urla to Gudiyari and Urla to Raipur includes the

requirement of Chhattisgarh only and is not the requirement of SLDC to WRLDC link

and as such its cost should not be pooled.

In this context, WRTS-I representative clarified that the above link is essentially

ITEM No.17 ANTICIPATED POWER SUPPLY POSITION IN WESTERN

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

The Committee noted the anticipated power supply position in the region for the period from June, 2009 to August, 2009 as furnished at Annexure-17. It was noted that this period under consideration was monsoon season and the regional demand was likely to be low as compared to summer period. The unrestricted demand would vary from 31900 MW to 33800 MW and deficit would vary from 0.22 % to 11.40 %. In terms of energy, the unrestricted requirement would be 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, MP, Goa, DD and DNH was 910 to 1989 MW, 223 to 396 MW, 2816 to 3940 MW, 144 to 1336, 84 to 122 MW, 29 to 45 MW and 28 to 63 MW respectively.

Although deficit was expected to be comparatively less than other peak period due to monsoon season, Constituent states were requested 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. WRP Committee noted.

Western Region System – Salient Features

• Largest Regional Grid with highest installed Generation capacity (43040 MW)

• Geographically large states with high Power demands i.e. Maharashtra(~14000 MW), Gujrat(~12000 MW), M.P.(~7000 MW)

• Progressive Constituents with high Industrial & Agriculture growth

• Western Region is progressive in adopting to new Technology

Need for PMUs & WAMS Technology

• Increasing Stress on Transmission Grids– Grid is Interconnected– Open Access– Inter-Regional Power Trading

• Lack of tools for monitoring Dynamic behaviourof grid– Existing tools are not adequate

• Monitor & then “estimate” the steady state• Heavy dependence on Dispatcher’s

knowledge

Smart Grid functions

SMART GRID ENVISAGES TO ACHIEVE:• Be able to heal itself • Motivate consumers to actively participate in

operations of the grid • Provide higher quality power that will save money

wasted from outages • Accommodate all generation and storage options • Enable electricity markets to flourish • Run more efficiently
