Unquote

WRP Committee may like to discuss and confirm the minutes. ITEM No 2: SIGNING OF PPA WITH RGPPL (FOR 5% ALLOCATED CAPACITY)

AND ITS SCHEDULING

2.1 As per MoP order, the scheduling of 5% capacity of RGPPL power i.e. 2% each to

DD & DNH and 1% each to Goa to DD & DNH and Goa could commence only after

completion of all formalities viz., signing of PPA, completion of the process for obtaining

necessary open access, opening of Letter of Credit by the beneficiaries of the

generating station commensurate with the allocated power etc. The issue was also

discussed in 9th WRPC meetings held on 16th January 2009 subsequent WRPC and

commercial meetings of WRPC. In the meetings RGPPL were requested for expediting

the signing of PPAs with beneficiaries. RGPPL had been stating that the matter was

under consideration and awaited their Board’s approval. RGPPL had been assuring that

same would be signed soon. The RGPPL beneficiaries of unallocated power had been

repeatedly requesting that their due share needs to be availed by them in view of

inadequate quantum of allocated power to them compared to their demand. Despite

above, the prolonged pending of expediting the PPA had been causing undue hardship

to them as arrangement to meet their demand from alternative costlier sources of power

had to be made by them pending receiving of approval of PPA document from RGPPL

Board. In the recent CCM held on 11th January 2011 RGPPL representative stated that

PPA is under final stage of approval by RGPPL Board. RGPPL board meeting was

scheduled to be held within a week’s time.

WRP Committee may like to discuss.

2.2 IEGC-2010 gives criteria for demarcation of control under scheduling and dispatch

code under which, Central generating station with multiple beneficiaries the scheduling

function is to be coordinated by the RLDC, ED, WRLDC, POSOCO vide letter no

WRLDC/OS/1664/2010/2312 dated 24.12.2010 addressed to Secretary, CERC have

sought direction of the Commission on transfer of jurisdiction of RGPPL from SLDC to

WRLDC with reference to the para 98 of the Commission’s order dated 18.08.2009 in

petition No. 283/2009.The allocations made by MOP to beneficiaries mentioned above

could not get implemented for want of signing of PPAs between RGPPL and the

beneficiaries and completion of the process for obtaining necessary open access,

opening of Letter of Credit by the beneficiaries of the generating station commensurate

with the allocated power etc., as at present coordination with respect to RGPPL is being

done by Maharashtra SLDC.

Committee may like to note.

ITEM NO 3.: MODALITIES FOR SHARING THE COST OF ENSURING HEALTHINESS OF NAPHTHA OPERATION AT KAWAS GPS OF NTPC.

In the 413th OCC meeting the operation and coordination committee of WRPC, had

agreed to technical requirement to run Gas Turbine of Kawas on Naphtha fuel for at

least half an hour at 70% load once in 15 days to ensure healthiness of naphtha circuit.

During 56th CCM, NTPC expressed that cost of ensuring the healthiness of Naphtha

circuit cannot be covered under O&M charges as this facility was introduced at later

stage and was not included in the original O&M cost of plant.

The issue was deliberated in 56th CCM and it was agreed that NTPC will give modalities

for sharing the cost to this account. NTPC vide letter dated 07.01.2011 (copy enclosed


2

at Annexure-3.1) had submitted the proposal for payment of additional cost of

generation of Naphtha fuel used during the healthiness check as above.

NTPC proposal suggests billing the difference in cost of generation on Naphtha used

and RLNG used during the healthiness check period to all the beneficiaries in proportion

to the allocation from the station.

Proposal of NTPC was discussed in 57th CCM wherein beneficiaries expressed that

details submitted shall be discussed with the their management and would convey their

comments within 10-15 days and the issue may be discussed in the TCC and WRPC to

be held in Feb. 2011 at Goa.

Comments were received from GUVNL vide their letter dated 21.1.2011 (copy at

Annexure -3.2) which suggests payment of variable cost of Naphtha when the Naphtha

based generation is requisitioned by the beneficiary and generator requires to ensure

that Naphtha circuit is healthy when it declares availability on Naphtha and as O&M

charges would adequately cover such cost the Naphtha charge proposed for above

check-period is thus not to be payable.

Committee may like to discuss. ITEM NO 4. : ALLOCATION OF POWER FROM KORBA STPS-III. MOP vide letter No.5/51/2010-Th.II dated 9.12.2010 has allocated power to the Western

Regional beneficiaries with effect from the date of commercial operation (copy enclosed

at Annexure-4). It is seen from the allocation order that 85 % power has been allocated

to WR beneficiaries while 15% of power is to be sold out side PPA. Considering this

aspect, for working out methodology of energy accounting for the same, following points

were outlined in 57th Commercial Committee meeting of WRPC held on 11.2.2010:

Long Term Open Access for Korba-III (500 MW) at Korba in Chhattisgarh was

granted to NTPC Ltd. by CTU in the meeting of WR constituents regarding LTOA

held on 23.02.2007 at Mumbai.

In the 27th Standing Committee Meeting and it was agreed to plan Korba III

STPS switchyard-Raipur 400 kV D/C line as transmission strengthening scheme.


3

In 9th WRPC meeting the Korba-III-Raipur D/c line was agreed as ATS of Korba-

III and PGCIL to construct the line on behalf of NTPC and NTPC bear full

transmission cost/charges of the same.

Actual date of commencement of LTOA for Korba-III is from the date of

commissioning of above system strengthening scheme and Signing of BPTA with

PGCIL for sharing of WR transmission charges corresponding to entire 500 MW

generation capacities. It was intimated by NTPC Ltd. and PGCIL that the BPTA

in this respect has already been signed. NTPC may have to apply for short term

open access till the time transmission system planned for Korba-III is completed.

Infirm power from Korba-III w.e.f. 25.11.10 was accounted in UI treating Korba-III

as separate entity under definition as a seller.

After declaration of COD of the Korba-III and till commissioning of Korba-Raipur

D/c line (under ATS) power from Korba-III may be scheduled under STOA and

Korba-III firm/unallocated/power sold outside long-term PPA to be treated as one

combined entity for UI calculation purpose (both infirm/STOA). Capping for

injection more than schedule and more than Installed capacity will be done as

applicable to seller category in accordance with UI regulations, 2010.

The Committee discussed the same as under:

WRLDC representative had stated that NTPC Ltd. shall require to apply for STOA for

power to be scheduled from the above Unit till commissioning of Korba-Raipur D/c line

(under ATS) and power under STOA would be allowed as per prevalent STOA

regulations. The Infirm power from the station would be allowed subject to grid security

and other operational constraints.

NTPC representative had stated that in view of unit no 7 of Korba STPS, under Stage-

III, now being retained as a regional station by MOP, Govt. of India vide letter dated

9.12.2010, and long term PPAs having been signed by all the constituents, evacuation

of unit no 7 of Korba STPS power needs to be ensured, on first priority basis, in utilizing

transmission capacity from the ATS of Korba STPS (2100MW) as the ATS of Korba

(2100 MW) was developed on n-I redundancy basis. He further added that, the

beneficiaries of WR have all these years serviced the investment made in the ATS of

Korba (2100MW). Therefore, power scheduled to them from unit no 7 of Korba STPS,


4

for which they also have long term PPAs, should get priority over any other short term

customer in this corridor.

GUVNL vide letter 21.1.2011 have expressed that as beneficiaries of WR are serving

cost of transmission evacuation associated with Korba STPS (2100 MW) including for

redundancy & have opined that as LTOA has higher priority over STOA which is

granted by RLDC on margins available after meeting LTOA requirement. Therefore the

beneficiaries have first right for STOA of transmission capacity utilization. GUVNL have

requested to discuss methodology and modalities by the Commercial Committee

considering the above aspects. NTPC have also requested that the modalities may be

discussed in detail.

As the LTOA is to get effected after commissioning of the associated system of Korba –

III, the power scheduling after COD is to take place under STOA on the basis of system

margins available. In view of the same and the suggestions made by the constituents as

above, the detailed methodology of energy scheduling and accounting under

LTOA/STOA conditions is to be worked out, as also with reference to treatment of

portions of allocated power under ISGS and power sold outside long-term PPA,

payment for ISTS charges by NTPC Ltd. etc.

TCC/WR Power Committee may like to discuss so that Commercial Committee would work out detailed methodology for accounting accordingly.

ITEM No.5: DECISIONS TAKEN DURING 30th MEETING OF STANDING COMMITTEE ON POWER SYSTEM PLANNING IN WR HELD ON 27.12.2010 AND SPECIAL WRPC COMMITTEE MEETING OF STATE TRANSMISSION UTILITIES AND BENEFICIARIES OF WR HELD ON 05.01.2011

generation of M/s India Bulls at Sinnar in Nasik District. In view of the same they have

planned parallel additional corridors in Dhule-Nashik-Malegaon area and therefore had

suggested POWERGRID to review the decision of establishing HVDC s/s at Dhule with

+/- 600 kV Raigarh (Kotra) – Dhule (PG) HVDC Bipolar link and 400 kV interconnecting

lines with Malegaon, Nashik, Dhule(MSETCL) which POWERGRID had agreed .

GETCO had indicated that in case the HVDC Station was not required at Dhule the

same may be shifted to Vadodara.

In the 31st meeting of Standing Committee on Power System planning in WR held on

27.12.2010, modifications requested by MSTECL in the Transmission System

associated with IPP projects in Chhattisgarh taking into account 3300MW generation

project proposed near Dhule was deliberated.

In the meeting it was concluded that at present no additions/deletions to the already

planned transmission system is to be done. It was decided that 400 kV interconnections

from Dhule (PG) to Malegaon and Nasik could be reviewed in a year’s time frame, if

required.

WRP Committee may concur recommendation of Standing Committee on Power System Planning in WR. 5.1.2 ESTABLISHMENT OF 765/400KV GIS S/S AT PUNE UNDER

KRISHNAPATNAM UMPP

PGCIL have intimated that during 15th WRPC Meeting, while expressing difficulties by

POWERGRID in acquiring land at Pune for establishing AIS at Pune, MSETCL had

opined that POWERGRID should go in for AIS instead of proposed GIS at Pune and for

difficulties in availability of land MSETCL shall assist for taking up at Government level if

POWERGRID required so.

Regarding establishment of GIS 765/400 kV s/s at Pune, MSETCL was requested to

resolve the issue regarding land availability for AIS by 30th November 2010 else

POWERGRID may go in for GIS s/s.

In the 31st meeting of Standing Committee on Power System planning in WR held on

27.12.2010, the proposal of 765/400 kV GIS substation at Pune was agreed. WRP Committee may concur recommendation of Standing Committee on Power System Planning in WR. 5.1.3 LAND REQUIREMENT FOR 400/220 KV GIS SUBSTATION AT DAMAN PGCIL have intimated that during 15th WRPC meeting, the matter regarding acquisition

of 8-12 acres of Land for establishing 400/220kV GIS station at Daman by PGCIL, had

been deliberated. PGCIL has intimated that as on date no land has been allocated

which is causing delay in preparation of Feasibility Report and tying up the funding

agency. However, DD representative stated that they have identified the land for

substation and the necessary formalities for acquisition are in advanced stage. WRPC

noted the same. Demand Note for 72,200 Sq Mtrs of land is yet to be received from

Daman Administration.

WRP Committee may like to note.

5.1.4 LAND REQUIREMENT FOR ESTABLISHMENT OF 765/400 kV GIS S/S AT VADODARA

PGCIL have intimated that during 15th WRPC meeting, it was decided that the

availability of 125-130 acres of land is very difficult in the vicinity of Vadodara and GIS

s/s may be installed instead of AIS s/s for which land requirement is to be tune of 50-60

acres. PGCIL intimated that to avoid further delay they are going ahead in initiating the

process of acquisition of land. WRP Committee endorsed the above recommendation

of TCC. POWERGRID have intimated that it has put up application for acquisition of 69.8 acres

of land on 20.12.2010 and have requested GETCO to please assist in identifying

suitable land for acquisition.

WRP Committee may like to note. ITEM No.6: RECOMMENDATIONS OF PSDF GROUP ON PROPOSAL FOR

PROCUREMENT OF ERS SUBSTATIONS PGCIL vide above letter dated 25.1.2011 have intimated that the PSDF Group

consisting of members from MSETCL, GETCO, MPPTCL, CSPTCL, NTPC, WRLDC,

POWERGRID and WRPC felt that it was difficult to accommodate the ERS equipment

at the existing Substations considering overall dimensions of the trailer-equipment and

its weight. As such, Committee had not recommended for procurement of ERS

substations at 400 kV level in this phase. The Committee had suggested that the

procurement for ERS for lower kV level i.e. 220 kV could, however, be explored by

PGCIL. WRPC agreed to the recommendation of PSDF group and did not recommend

the procurement of ERS-substations at 400 kV level in this phase and suggested that

the procurement for ERS of lower kV level i.e. 220 kV, 110 kV / 132 kV could, however,

be explored by the constituent states.

PGCIL has submitted that this kind of equipment is meant not only for installation in a

Substation, these can be installed anywhere as and when required below the EHV

Lines even, where there is no space constraint. Further the Unit can cater load at 33kV

level upto 33% of the rated capacity of the Transformer besides establishing

connectivity over 400 /220 kV level. The unit is ideally suited for emergency

requirement during any natural calamity and can also be used for providing reliable

power supply at important load centre at short notice. Powergrid has requested to

reconsider the procurement of two (2) Sets of ERS- Substations at 400kV level for WR.

WRP Committee may discuss.

agreed that, the pooling of wheeling charges payable to Maharashtra & Gujarat with

POWERGRID charges would be reviewed, in case POWERGRID faces payment

problems. As some of the beneficiaries viz. MPTRADECO, CSPDCL, D&D, DNH,

Jindal & Torrent Power are deducting TDS from amount payable to POWERGRID,

despite the decision in 13th WRPC meeting as above, POWERGRID have urged that

due to the same, they are not in a position to continue billing the wheeling charges in

their Bills for GUVNL & MSEDCL and that from Jan’11 concerned Licensees may raise

the bill at their end & collect money from the concerned directly.


10

In this context, it is required that as agreed in 13th WRPC meeting PGCIL will continue

to include billing of transmission charges payable to MSETCL and GETCO for wheeling

of Central sector power in their bill which they had stopped billing the same from Aug.

2009 onwards as the constituent State were deducting TDS and Service tax at their end

while making transmission charges payment to PGCIL. However PGCIL had agreed

with the condition that no deduction on account of Service Tax and TDS will be done by

the beneficiaries at their end and it should not be implicated on PGCIL. As all the

beneficiaries had then agreed to the same.

In 15th WRPC meeting, it was intimated by MSETCL that monthly wheeling charges

payable to Maharashtra have not been credited by POWERGRID w.e.f. Aug-2009.

POWERGRID had intimated that the credit is being passed on to all the constituents as

per the REA details on monthly basis. POWERGRID intimated that the accumulation

arising out on revising the REA is paid immediately upon receiving the same from other

paying utilities. It had further intimated that credit could not be passed on to MSETCL

due to non-receipt of the same from GUVNL on account of arrears due for the years

2004-05-2008-09. However, they had started billing and passing the credit to MSETCL

on monthly basis w.e.f. September 2010 and the previous dues w.e.f. Aug-2009 will be

cleared in due course. POWERGRID were requested for continuing to release amount

every month to Maharashtra and Gujarat the amount received from all paying utilities

corresponding to each month as per the REA details issued.

In line with the above decisions of the Committee, it is requested that the utilities may

release the payments to PGCIL on account of the wheeling charges so that payments to

the receiving utilities may be cleared by PGCIL early so that the existing mechanism is

can be followed smoothly and the difficulties expressed by PGCIL are overcome.


ITEM NO. 9: REPLACEMENT OF INSULATORS AND EARTH WIRE DETERIORATED DUE TO EXCESSIVE POLLUTION IN TRANSMISSION LINES IN SOUTH GUJARAT

POWERGRID has intimated that due to excessive pollution in south Gujarat,

transmission lines of POWERGRID around Surat are severely affected. Insulator

flashover, failure of insulators and earth wire due to corrosion is very frequent. To


11

ensure uninterrupted service, POWERGRID has taken up replacement of Insulators

besides their cleaning twice in a year and replacement of Earth wire in the polluted

stretches. POWERGRID have intimated that it has already incurred an expenditure of

approx Rs. 3.85 Crs. and another Rs. 4 Crs is estimated in procurement and

replacement of balance insulators and earth wire to eliminate vulnerability of

transmission system for reasons beyond the control of POWERGRID. In view of the

circumstances outlined above, POWERGRID has proposed following :

1) Reimbursement of cost of Insulator and Earth wire replacement to POWERGRID.

2) The outages required for Insulator replacement & cleaning process and earth wire replacement may be treated as deemed available.

WRP Committee may like to discuss. ITEM No. 10: PLANNING AND REPLACEMENT OF SCADA/EMS SYSTEM IN WR The above item was discussed in 12th WRPC meeting held on 16.01.2010 and it was

decided in the meeting that WR constituents would implement their SCADA/EMS

systems as per their plan but common specifications would be prepared, discussed in

SCADA committee meeting for further action. POWERGRID had earlier suggested

three approaches to this issue and had requested the constituents to choose one that

best fitted their requirement.

a) PGCIL may provide consultancy services on turnkey basis from concept to commissioning. Funds have to be arranged by constituents and PGCIL’s overhead charges shall be applicable

b) PGCIL may arrange funds & execute project on turnkey basis with appropriate administrative charges. Constituents may repay the project cost over the life span of the system. However such proposal can be considered by PGCIL only if such investment proposal is accepted by CERC.

c) Constituents may implement their system as per their plan. In such case common time frame and data interchange strategy have to be firmed up.

During 8th SCADA –O&M Committee meeting held at WRLDC on 7.01.2011, AGM

(LD&C), POWERGRID informed that recently, NR constituents in NRPC meeting had

agreed for a unified approach of control centre SCADA/EMS hardware / software up

gradation to be carried out by POWERGRID and recovery by way of tariff similar to the

model adopted in ULDC schemes. Based on the NRPC decision, POWERGRID would

approach Central Regulatory Commission for approval of the unified approach of


12

SCADA/EMS up gradation and tariff proposal. AGM, WRLDC stated that in view of the

latest development in NR, the decision taken in WR earlier may be reviewed. However,

depending on the decision to be taken by WR constituents, the final approach to

replacement issue would be frozen in consultation with LD&C, POWERGRID. He also

informed that considering the time line of around two years required for replacement

activity, it would be prudent to arrive at the final approach as early as possible. He

informed that the the Present LTSA time line is fixed for five years from 14th Oct 2009

and there is an exit option at the end of 3 years by payment of additional demobilisation

charge of 10% of the balance charges of two years.

ED, WRLDC suggested that the future system should be planned with the two year

clock starting from 1st April 2011 and the new system should be commissioned by 1st

April 2013. Both the new system and the old ULDC would operate in parallel for a year

so that the new system could be evaluated for its stability and reliability and the ULDC

system could be phased out at the end of 5 year LTSA.

The matter was further deliberated in 8th SCADA –O&M Committee meeting and

outcome is recorded as under:

• MSETCL representative stated that the up gradation of SCADA/EMS

systems of MSETCL had recently been awarded on Siemens and the work was in advanced stage.

• GETCO representative informed that unified approach of SCADA/EMS up gradation is suitable to them however the final decision could be taken at WRPC forum.

• CSPTCL representative informed that unified approach of SCADA/EMS up gradation is suitable to them however the final decision could be taken at WRPC forum.

• MPPTCL representative informed that the matter needs further deliberation in MPPTCL forum and they would communicate MPPTCL opinion tentatively in a week’s time. MPPTCL vide letter No. 07-05/E&T/65 dated 24.01.2011 (copy enclosed at Annexure-10) have confirmed that MPPTCL may also like to replace their SCADA/EMS system through unified approach through PGCIL.

ITEM No. 11: ESTABLISHEMNT OF 128Kbps LEASED CIRCUIT As discussed during 7th SCADA meeting, 128Kbps leased circuit have been

commissioned between SLDC Jabalpur - WRLDC Mumbai and SLDC Gotri – WRLDC

Mumbai. The other circuit between SLDC Bhilai and WRLDC Mumbai and Tarapur-I

and WRLDC Mumbai are under progress. The leased circuit have been very helpful

during communication failure in the recent past and vital ICCP data has continued to

flow between SLDCs and WRLDC. ED, WRLDC opined that considering the critical

nature of grid operation and possible failure of only one communication path, it would be

proper to make a back up leased line with MSETCL Kalwa and WRLDC Mumbai also,

though both are in same city. It was discussed and decided that WRLDC would check

with MSETCL for proper port availability and initiate the process of taking 128Kbps

leased line between SLDC Kalwa and WRLDC Mumbai.

In this context, during 8th SCADA meeting DGM, WRTS-I informed that the scheme that

included the OFC links on Maharashtra and Reliance lines and was proposed in last

meeting would serve dual purpose of providing alternate path for central sector RTU

data as well as the redundancy to existing ICCP links between SLDC, Kalwa and

WRLDC. The part of the link would involve hiring of fibers from Reliance. An estimate

from Reliance obtained by WRTS-I and the same along with the scheme details is

enclosed at Annexure-11. After detailed deliberation on subject matter, the Committee

agreed for the scheme which would now be put up in next WRPC for approval.

WRP Committee may discuss and approve.

ITEM No. 12: OPGW BASED COMMUNICATION LINK TO S/S OF PGCIL IN WR The matter was discussed and the Master Communication Plan for WR was approved

by WRPC in their 14th meeting held on 19th August 2010 at a cost of Rs 144.35cr. In the

same meeting, MPPTCL requested for inclusion of their communication requirements in

the master communication plan. The cost estimate for wide band equipments & node

proposed in MP state were required to be worked out. It was suggested by

POWERGRID that the terminal equipment for the MPPTCL requirements could be

included in the Master Communication Plan but OFC laying on MPPTCL lines would be

taken care of by MPPTCL. Alternately, if MPPTCL choose to procure the terminal


14

equipments as well, the technical interface details of the same would be made available

to MPPTCL.

In the finalized master communication network, following two lines being constructed by

IPTC were decided to be included in the network.

(i) Parli (PG) – Sholapur (PG) – 225Km.

(ii) Sholapur (PG) – Kolhapur (PG) – 167Km

The matter was discussed in 8th SCADA O&M Committee on 7.01.2011 and it was

proposed to include the following MSETCL lines in the proposed network :

(i) Parli (PG) – Parli (MSETCL).

(ii) Parli (MSETCL) – Sholapur (Lamboti) MSETCL

(iii) Sholapur (MSETCL) – Sholapur (PG)

(iv) Sholapur (MSETCL) – Kolhapur (MSETCL)

MSETCL representative agreed for the proposal. AGM, WRLDC stated that with this

modification in master communication plan, the respective MSETCL stations would as

will be covered for telemetry requirements of WR SCADA systems. Further, MSETCL

agreed to permit the laying of fibres wherever MSETCL fibres were not being planned.

For lines where MSETCL had initiated process for laying fibre, the fibres could be

spared for the master communication plan. It was informed that the Master

Communication Plan for WR as approved by WRPC and indicated above is under

process by POWERGRID and the NIT would be floated by March 2011 with a

commissioning time line of 30 months, to be taken up in a phased manner.

WRP Committee may like to note. ITEM No. 13: TELEMETRY TO SLDC FROM CENTRAL SECTOR STATIONS The matter was discussed in the 12th WRPC meeting and it was decided that PGCIL will

address the issues concerning frequent failure of communication between RLDC and

SLDC resulting in interruption of real time data communication to SLDC. Also, PGCIL

will discuss the matter with the supplier to check the feasibility of providing an additional

port in the gateway for data communication to SLDC in respect of substation with


15

automation. The above matter will be discussed by the SCADA O&M Committee of WR

and the outcome will be put up to TCC/WRP Committee for further directions, if any.

During 8th SCADA O&M Committee meeting held on 7.01.2011, LD&C, POWERGRID

informed that these locations were equipped with SAS/GAS with interface converters for

real time data reporting. He further informed that most of the locations were housing

SAS schemes that had dual ports for reporting to RLDC and no spare port was

available for reporting to SLDCs.

ED WRLDC informed that as per IEGC clause 6.4, all players are governed by control

area concept including real time data flow and thus real time data from the stations

coming under RLDC control area should be made available to RLDC. He further

informed that backup MTNL/BSNL leased circuits have been taken by WRLDC for ICCP

data continuity, as such central sector data to SLDCs is assured on the prevailing

communication network. Hence, same data reporting to SLDC through wide band

communication would be redundant. Therefore, it was concluded that direct reporting of

central sector station to SLDC would not be taken up.

Committee may discuss and approve. ITEM No.14: ONGOING TRANSMISSION SCHEMES IN WESTERN REGION

It is intimated that in accordance with the decision taken in the 12th WRPC meetings

held on 16th January 2010 at Vadodara, 4th meeting to review ongoing transmission

ITEM No.16: INCLUSION OF NON-ISTS ASSETS FOR IMPLEMENTATION OF

POINT CONNECTION METHOD FOR POINT OF CONNECTION CHARGES

16.1 CERC Regulations, 2010 on "Sharing on transmission charges and Losses"

regulation 2010 are to come in force from 1.4.2011. The determination of transmission

charges as per this Regulation is required to be limited to the network owned, operated

and maintained by the ISTS Licensees or those transmission licensees / SEBs whose

assets have been certified by RPCs as being used for inter-state transmission. During

15th WRP Committee meeting The WRP Committee approved the criteria and the list of

state owned Interstate / Inter-regional lines for certification as ISTS lines. It was also

agreed that any other non-ISTS line that comes up and meets the criteria agreed as

above, may be considered for certification as ISTS line. Accordingly list of state owned

Interstate / Inter-regional lines certified as ISTS lines as approved above was forwarded

to implementing agency. Also the list was sent to the concerned non- ISTS Licensees

for furnishing YTC of the respective lines certified as above to NLDC.

from this generating station to the State points beyond which no direct connectivity to

nearest CTU point exists, could not be arrived at. It was agreed that issue may be

further discussed in next CCM after constituents further examine various aspects in this

context.

Committee may like to note. ITEM NO.17 : EXTENSION OF THE DATE OF OPERATION OF CERC (SHARING OF

INTER-STATE TRANSMISSION CHARGES AND LOSSES) REGULATIONS, 2010.

Central Electricity Regulatory Commission, Regulations, 2010 on Sharing of Inter-State

Transmission Charges and Losses were to take effect from 1.1.2011. NLDC the

implementing agency of the above Regulations have submitted to Commission the,

details of Point of Connection charge worked out based on the data and network details

received from the various DICs. It has sought more time for submitting the modified


21

procedure after incorporating comments of stakeholders and decision of CERC on the

issues raised. CERC vide order 30.12.2010 has directed that the Regulations shall

come into force with effect from 1.4.2011.

As the States want to see the implication of the new method of sharing of transmission

charges through calculation of actual transmission charges through both the

methodologies before the same gets implemented, constituents may see the

transmission charges worked out through both methodologies which shall be

maintained on the NLDC website w.e.f 01.02.2011.

Committee may like to note.

during 15th WRPC meeting, the mechanism of compensation of losses for transfer of

power between WR and NR over MPPTCL and GUVNL network was discussed and it

was decided that the compensation of losses shall be done by applying necessary loss

compensation to the actual inter regional power transfer on 220kV Badod-Kota and

220kV Badod-Modak inter-regional links and 400kV Zerda-Kankroli inter-regional link

approved by State Regulatory Commission for State Transmission System in respective

states and this loss may be pooled among the WR constituents and have suggested on

the following:-.

21.1 Mechanism for compensation of losses on transfer of power to NR over GUVNL Network.

(i) In case of GUVNL only one link i.e. 400 kV Zerda- Kankroli is mentioned in the

minutes and have suggested that Power transfer over 400kV Zerda-Bhinmal link is also

required to be considered while giving loss compensation to the actual power transfer.

(ii) Clarification on application of loss compensation to both export and import of power

through this links has been sought by WRLDC and have proposed that compensation of

loss to both export and import shall be applied on power through these lines lines viz.

400 kV Zerda- Kankroli and 400kV Zerda-Bhinmal. 21.2 Mechanism for compensation of losses on transfer of power to NR over

MPPTCL Network. WRLDC have stated that in reality four numbers of STU network is used for power

transfer between WR and NR, i.e. 220kV Auraiya-Malanpur, 220kV Auraiya – Mehgaon,

220kV Kota- Badod, 220kV Modak-Badod.


27

WRLDC has proposed that the compensation of loss shall be applied to the net

transaction over these four links between WR and NR in each 15- minute time block.

Also clarification has been sought that whether to apply loss compensation to both

export and import of power through these links and has proposed that, compensation of

loss shall be applied to both import/export of power transfer between WR and NR using

MPPTCL network.
