MINUTES OF 50th MEETING OF COMMERCIAL COMMITTEE HELD ON 8th AUGUST 2008 AT WRPC, OFFICE, MUMBAI
The 50th Commercial Committee meeting of WRPC was held at WRPC, Office, Mumbai on
8th August 2008. The list of the participants is enclosed at Annexure-I.
Shri P. Patel, Member Secretary, WRPC welcomed all the participants of the meeting. He
also welcomed Shri M. G. Raoot, who had recently taken over as GM, WRLDC. He added
that experience of Sh. Raoot in North-East and Eastern Regions will be helpful in
deliberations in WRPC. He stated that the issues regarding IPPs for whom LTOA has been
granted by CTU have been included in the agenda in light of Hon’ble CERC order dated 7th
May 2008 in the matter of clarity regarding control areas and demarcation of scheduling
between RLDCs and SLDCs. He hoped that most of the issues included in the agenda will be
resolved and the deliberations would further set guidelines for IPPs coming in the future. He
added that in Chhattisgarh State itself around 40 IPPs with total capacity of around 40,000
MW are expected in a span of 4-5 years. He hoped that guidelines set in today’s meeting will
be helpful in applying the same to the above IPPs coming up in future.
He then, requested Shri S.G. Tenpe, Superintending Engineer (Comml.), WRPC to take up
Agenda for discussion.
ITEM No.1: CONFIRMATION OF THE MINUTES OF THE 49th MEETING OF COMMERCIAL COMMITTEE
Superintending Engineer (Comml), WRPC stated that the Minutes of the 49th meeting of
Commercial Committee held on 17th March 2008 at Jabalpur were circulated to the
constituents vide WRPC letter No.WRPC/Comml-I/2/CCM/Min/2008-2768 dated 1.04.2008.
He stated that GUVNL vide letter dated 6.8.2007 requested for correction in line-1 of Para-3

Minutes of 50th CCM held on 8th August 2008 2
ITEM NO.2: CLARITY REGARDING CONTROL AREAS AND DEMARCATION OF SCHEDULING BETWEEN RLDCs AND SLDCs
2.1 Superintending Engineer (Comml.), WRPC stated that Hon’ble CERC in Petition No.
58/2008 vide its order dated 7th May 2008 (suo motu) gave directions in the matter of clarity
regarding control areas and demarcation of scheduling between RLDCs and SLDCs to be
adopted in future. The demarcations of scheduling responsibilities are as below:
a) RLDCs to coordinate the scheduling of Ultra-Mega Power Projects.
b) RLDCs to coordinate scheduling of large privately owned power plant (of 1000 MW
or larger size) in which States other than the host State have substantial permanent
share (50 % or more).
c) Power plant not meeting the above criterion (a) and (b), should be scheduled by the
SLDC of the State in which they are located.
d) The above guidelines have been specified as a general guideline. However, there
could be exceptions, for operational expediency, by a mutual agreement between the
concerned RLDC and SLDC.
e) The SLDC which is responsible for coordinating the scheduling of a generating
station shall also be responsible for:
(i) Real-time monitoring of the station’s operation,
(ii) Checking that there is no gaming in its availability declaration,
(iii) Revision of availability declaration and injection schedule,
(iv) Switching instructions,
(v) Metering and energy accounting,
(vi) Issuance of UI accounts,
(vii) Collections/disbursement of UI payments,
(viii) Outage planning, etc.
f) It is necessary that the concerned SLDCs are immediately geared up for undertaking
the above tasks.
g) This order may be treated as an elaboration of clause 5.1 (e) and section 6.4 of Indian
Electricity Grid Code.
2.2 In view of the aforesaid directions of the Hon’ble CERC, Superintending Engineer
(Comml), WRPC invited the attention of the constituents to the relevant provisions in Indian
Minutes of 50th CCM held on 8th August 2008 3
Electricity Grid Code (IEGC) regarding providing of data and communication facilities and
filing of copy of bilateral agreements etc. The relevant paras of Indian Electricity Grid Code
(IEGC) viz. 4.10-“Data and Communication Facilities” and para No.6.4.11-“Demarcation of
Responsibility”are reproduced below:-
“ 4.10 - Data and Communication Facilities
Reliable and efficient speech and data communication systems shall be provided to
facilitate necessary communication and data exchange, and supervision/control of the
grid by the RLDC, under normal and abnormal conditions. All agencies shall provide
systems to telemeter power system parameter such as flow, voltage and status of
switches/transformer taps etc. in line with interface requirements and other guideline
made available to RLDC / SLDC. The associated communication system to facilitate
data flow upto RLDC/SLDC, as the case may be, shall also be established by the
concerned agency as specified by CTU in connection agreement. All agencies in
coordination with CTU shall provide the required facilities at their respective ends
and RLDC/SLDC as specified in the connection agreement.
6.4 Demarcation of Responsibilities
…..
…..
6.4.11 The regional constituents shall enter into separate joint/bilateral
agreement(s) to identify the States shares in ISGS projects (based on the allocations
by the Govt. of India, where applicable), scheduled drawal pattern, tariffs, payment
terms etc. All such agreements shall be filed with the concerned RLDC(s) and RPC
Secretariat, for being considered in scheduling and regional energy accounting. Any
bilateral agreements between constituents for scheduled interchanges on long-term
/short-term basis shall also specify the interchange schedule, which shall be duly filed
in advance with the RLDC. ”
Member Secretary, WRPC Committee stressed the need for providing of necessary data
and communication facilities by the State utilities as envisaged in IEGC. He also
requested the IPPs /State utilities to forward a copy of bilateral agreements well in
advance to WRLDC and WRPC as well to facilitate scheduling and regional energy
accounting.
Minutes of 50th CCM held on 8th August 2008 4
2.3 In regard to provision in the above CERC’s directions dated 7th May 2008 that these
guidelines have been specified as a general guideline and however, there could be exceptions,
for operational expediency, by a mutual agreement between the concerned RLDC and SLDC
GUVNL representative requested the members may discuss the general exceptions in all
LTOA cases. In this context, it was observed that these exceptions need to be seen and
discussed on case to case basic and there cannot be general guidelines for exceptions.
2.4 GUVNL representative further raised the issues concerning applicability of UI
mechanism in the State in case it is different from the Region, estimation of losses, its
allocation, scheduling of IPPs partly or as a whole etc.
In this context, Superintending Engineer (Comml.), WRPC stated that the station which falls
under the control area of SLDC is expected to be governed as per the State grid code and UI
mechanism will accordingly be applicable. Further, responsibility of coordinating the
scheduling, real-time monitoring, checking that there is no gaming in its availability
declaration etc. falls under the control area of the SLDC. Also, it will be the responsibility of
concerned SLDC to furnish 15 min. time block schedule of quantum of power injection to the
grid. In case, the Station falls under the control area of RLDC, then scheduling, coordination
etc. of the whole station will be carried out by concerned RLDC.
2.5 General Manager, WRLDC stated that the above cited order by CERC is suo-motu
order and there would not be any problem whether an IPP is scheduled by RLDC or SLDC.
He added that numbers of IPPs are coming up in future and handling the same by RLDC’s
would be extremely difficult. He further added that logistics at RLDC and at various SLDCs
are different in terms of class, location of CTs, PTs, CVTs, SEMs etc, and UI rates
applicability dependent on CERC or SERC regulations, applicable to region or state. Also,
sufficient time may also be given to all SLDCs to gear up for scheduling of respective
generation projects in their states. Therefore, the case of each IPP need to be discussed one
by one and the decision of RPC would be final and binding on all. The whole idea behind the
above order by CERC is to transfer the responsibilities as given above in para 2.1(e) above
from RLDC to SLDCs so that SLDCs are geared up their infrastructure in due course.
Therefore, the LTOA cases slated for discussion in agenda need to be discussed on case to
case basis irrespective of their connectivity to the grid and its allocation of power from these
IPPs.
Minutes of 50th CCM held on 8th August 2008 5
2.6 The committee also deliberated the issues concerning readiness of SLDCs for
taking up activities as out lined in para 2(e) in the context of CERC’s directions dated
7th May 2008. After detailed deliberation the following action plan was agreed:
(i) The SLDCs of WR shall have to confirm their readiness for coordinating the
scheduling of IPPs under their control areas according to CERC guidelines,
its real-time monitoring, checking that there is no gaming in its availability
declaration, revision of availability declaration and injection schedule, etc.
The concerned SLDCs will be responsible for metering and energy
accounting, issuance of UI accounts and collection /disbursement of UI
payments.
(ii) The SLDCs should be ready to carry out activities as above at least three
months prior to commissioning of first unit of the concerned IPP. All
constituent States of WR agreed to confirm the same within one month time.
(iii) The concerned SLDCs will carry out necessary mock billing and be ready to
take up the above activities well in advance prior to commissioning of the
IPPs generating unit and its connectivity to the grid.
(iv) In case of non readiness of the concerned SLDC to take up these activities
and to have smooth operation and connectivity of the IPP to the grid, IPPs
scheduling etc. indicated in (i) above, will be carried out by WRLDC till the
SLDC concerned geared up. The responsibility of scheduling and co-
ordination of such IPPS will be reviewed by WRLDC, WRPC and the
concerned SLDC, once it is ready to take up the same.
ITEM NO. 3: LTOA OF NSPCL 500 MW (2x250) PROJECT AT BHILAI, CHHATTISGARH
3.1 Superintending Engineer (Comml), WRPC stated that Long Term Open Access for
transfer of 170 MW (power from their proposed generation project at Bhilai Expansion
Power Project (BEPP), 2x250MW viz. 100 MW to UT of DNH and 70 MW to UT of DD
was granted by CTU in the meeting regarding long-term open access applications held with
Minutes of 50th CCM held on 8th August 2008 6
WR constituents on 30.09.2006. No open access was sought for balance capacity as 280 MW
power was proposed to be transferred to BSP/SAIL through a dedicated system owned by
NSPCL and 50 MW to Chhattisgarh through exclusive CSEB system. It was also decided
that the actual date of commencement of open access will be from the date of availability of
the identified transmission system strengthening and 400/220 kV, 2x315 MVA transformers
at NSPCL generation switchyard along with 220 kV transmission system identified for
interconnection with NSPCL & CSEB as well as transmission system of Vindhyachal-III,
Sipat-I & II including signing of BPTA with POWERGRID by M/s NSPCL or by DNH and
DD for sharing of WR transmission charges corresponding to 170 MW generation capacity.
The following transmission strengthening scheme was agreed to which will be built, owned,
operated and maintained by M/s NSPCL:
(i) NSPCL generation voltage step-up at 400 kV level
(ii) NSPCL – Raipur 400 kV D/c
(iii) 400/220 kV, 2x315 MVA transformers at NSPCL generation switchyard
(iv) 2 Nos. of 400 kV bay extension at 400/220 kV Raipur substation to accommodate
NSPCL- Raipur 400 kV D/c line
3.2 S.E. (Comml), WRPC further stated that associated transmission system is not yet
commissioned. Further, one unit has been synchronized and yet to be coal fired and
scheduling of power from BEPP (2x250MW) station has not yet started. He added that earlier
the requirement of SEMs, its locations, was finalized by the Commercial Committee for
energy accounting purpose keeping in view that the scheduling of injection of power to DD
& DNH (170 MW) from this generating station to WR grid will be carried out by WRLDC.
However, in view of CERC order dated 7th May 2008 in the matter of clarity regarding
control areas and demarcation of scheduling between RLDCs and SLDCs and as the
scheduling and accounting this IPP has not yet been commenced, it would be appropriate that
monitoring, scheduling of 2x250 MW NSPCL units should be governed by this CERC order.
He further added that considering the connectivity of the above Station to Bhilai Steel plant
/CSEB and only part transfer of power to DD and DNH scheduling, monitoring etc. of this
IPP by SLDC, CSEB is the best option. Accordingly, SLDC, CSEB will be responsible for
coordinating the scheduling of a BEPP (2x250 MW) generating station, its monitoring,
issuing of UI accounts, etc. as given at Item 2.1 (e) above. WRLDC also concurred with this
arrangement.
Minutes of 50th CCM held on 8th August 2008 7
3.3 M/s NSPCL representative stated that the 1st Unit (250 MW) of Bhilai Expansion
Power Project was synchronized with the grid on 20th April 08 and coal firing in August 08.
He intimated that M/s NSPCL have signed PPAs with all the beneficiaries of the project. He
further stated that transmission system for BEPP was initially envisaged to be at 220 kV level
matching with the requirement of Bhilai Steel Plant (BSP). Subsequently to facilitate its
connectivity to CTU transmission network, it was decided to step up the voltage upto 400 kV
and connect to CTU system at Raipur. He further added that BEPP is connected directly to
ISTS and not an embedded generator. Also, presently BEPP is not directly connected to
CSEB system. He further added that metering arrangement has already been done by CTU to
enable scheduling and accounting by WRLDC/WRPC. Further, there is no intra-state ABT
or well-laid down procedure in Chhattisgarh and preparedness of Chhattisgarh SLDC for
scheduling and other aspects needed to be fully ascertained. Inviting attention to para-11 of
the above CERC order dated 7.05.08 i.e. such plants may already be planned to be connected
directly into the CTU network and metering of the plants injection may have already been
contemplated by the CTU, he requested that scheduling etc. of 2x250 MW generating unit at
NSPCL may be done by WRLDC.
In this context, CSEB representative stated that the status of 2x250 MW generating unit at
NSPCL i.e. BEPP is of CPP and not IPP and it is embedded in CSEB system. As its
scheduling, montoring etc. should be done by SLDC, CSEB.
3.4 CSEB representative agreed for scheduling, monitoring, issuing of UI account
etc. of Bhilai Expansion Power Project. SLDC, CSEB will furnish 15 minute time block
energy schedules of DD and DNH to WRLDC as per IEGC for calculation of drawl
schedules. Raipur end of 400 kV NSPCL-Raipur will be taken as one of the drawal
point of CSEB.
As one unit of 250 MW from the above project is likely to start on coal firing shortly,
Member Secretary, WRPC requested CSEB to confirm readiness of SLDC, CSEB to
take up above activities by end of Aug. 2008. CSEB agreed to the same. However, in
case of non readiness of the SLDC, CSEB to take up these activities and to have smooth
operation and connectivity of generating unit 2x250 MW of BEPP to the grid,
scheduling etc. will be carried out by WRLDC till the CSEB geared up. The
Minutes of 50th CCM held on 8th August 2008 8
responsibility of scheduling and co-ordination of the same will be reviewed by WRLDC,
WRPC and SLDC, CSEB once it is ready to take up the same.
ITEM NO.4: LTOA OF LANCO-AMARKANTAK 600 MW (2x300) AND PROPOSED (1X600 MW) PROJECT AT PATHADI, CHHATTISGARH
4.1 Superintending Engineer (Comml), WRPC stated that Long Term Open Access for
transfer of power to WR grid from first unit of 300 MW capacity of proposed generation
project of LANCO-Amarkantak Power Pvt. Ltd at Pathadi village, Distt. Korba in
Chhattisgarh was granted by CTU in the meeting regarding long-term open access
applications held with WR constituents on 30.09.2006. LILO of 400 kV Korba STPS- Sipat
S/c line at Pathadi generation project was agreed as transmission strengthening scheme,
which will be built, owned, operated and maintained by M/s Lanco Amarkantak.
Subsequently, LTOA for transfer of power to Northern Region from second unit of 300 MW
of above project was granted by CTU in the meeting held on 30.07.2007. The point of
injection from above project is the nearest ISTS interconnection viz. WR pooling station at
Sipat. The date of commencement of open access should be from the date of commissioning
of generation project and availability of the identified transmission system strengthening
scheme including signing of BPTA with POWERGRID for sharing of transmission charges
for Western Region corresponding to entire generation capacity. As indicated by M/s
LANCO, unit-1 is expected by Sept. 08 and unit-2 by Sept. 09. He further stated that M/s
LANCO vide letter dated 04.07.2008 (enclosed at Annexure-4.1) intimated plan for addition
of one more unit i.e. unit no.3 of 600 MW at the above project which is likely to be expected
by end of year 2011. LANCO further intimated that all necessary clearances are in place and
PPA is under finalisation with Chhattisgarh for evacuation of 315 MW and balance 285
would be supplied to other States.
PGCIL representative stated that LTOA for Haryana from Unit-2 had not yet been granted
due to non availability of transfer capacity on NR-WR corridor and the same will be
confirmed after availability of Barh transmission system.
4.2 In view of the future plan of capacity expansion at Pathadi upto 1200 MW, CTU had
identified the following system strengthening scheme, which was agreed in LTOA meeting
held on 30.07.2007:
Minutes of 50th CCM held on 8th August 2008 9
System strengthening scheme To be executed by
(i) Pathadi TPS – WR pooling station (near Sipat) 400 kV D/c (Quad) line
(ii) 400 kV Pathadi TPS-Korba lines (LILO of 400 kV Korba-Sipat line). The LILO arrangement is to be removed after execution of additional system strengthening scheme associated with the project.
As it is direct evacuation line interconnecting generation project with WR grid, it shall be built, owned, operated and maintained by M/s Lanco Amarkantak.
(iii) Establishment of 765/400 kV 3x1500 MVA WR pooling station near Sipat
(iv) 765 kV WR pooling station – Seoni 3rd Circuit (v) Installation of 765/400 kV 3x1500 MVA
transformer at Wardha to charge Seoni-Wardha lines at 765 kV level
To be carried out as an independent WR system strengthening scheme and shall be implemented by PGCIL.
In the LTOA meeting held on 30.07.2007, CTU stated that the actual date of commencement
of open access will be from the date of commissioning of transmission system strengthening
scheme including 400 kV WR pooling station-Pathadi TPS D/c (Quad) line, removing of
LILO arrangement at Pathadi TPS & restoration of LILOed 400 kV Korba-STPS-Sipat line to
its original configuration as well as availability of transmission system of various generation
project viz. Sipat I & II, Sipat-II supplementary schemes, Kahalgaon-II, Barh and all other
Western Region system strengthening schemes including WRSS-II scheduled for
implementation by that time frame.
4.5 Superintending Engineer (Comml), WRPC sated that considering the allocation of full
capacity of 2x300 MW to the States outside Chhattisgarh and also expected sale of 285 MW
from 600 MW unit outside the state of Chhattisgarh as indicated by M/s LANCO vide letter
dated 4th July 2007 (Annexure-4.1), it would be appropriate that coordination and scheduling
of power from LANCO-Amarkantak should be done by WRLDC. Accordingly, its weekly UI
account should be issued by WRPC secretariat.
4.6 CSEB representative stated that the current project capacity is 300 MW and another
300 MW will be commissioned by Sep 2009. As the project capacity is less than 1000 MW it
should be scheduled by SLDC, CSEB.
Minutes of 50th CCM held on 8th August 2008 10
4.7 Member Secretary, WRPC stated that it was appropriate to take the decision
regarding agency responsible for scheduling etc. of an IPP on the basis of ultimate
capacity of the project. He added that in this particular case, connectivity has been
planned by the CTU considering the total capacity of the project as 1200 MW. Further,
more than 50% of power from this project is expected to be supplied to the States
outside Chhattisgarh. Therefore, it is more logical and appropriate that as per CERC
order dated 7.05.08, the scheduling, monitoring etc. of this project should be done by
WRLDC.
General Manger, WRLDC while agreeing to the views of MS, WRPC stated that in case
the full capacity of the project, as planned, does not materialize in future the scheduling
of this project might be accordingly reviewed. However, at present it should be done
by WRLDC and its weekly UI account should be issued by WRPC secretariat.
PGCIL representative agreed to intimate the status of implementation of system
strengthening scheme, as agreed as part of LTOA separately.
ITEM NO. 5: LTOA OF JINDAL POWER LTD. (JPL) 1000 MW (4X250), PROJECT NEAR RAIGARH, CHHATTISGARH
5.1 Superintending Engineer (Comml), WRPC stated that M/s Jindal Power Ltd. (JPL)
has been granted Long Term Open Access by CTU in the meeting held on 30.09.2006 for
transfer of 500 MW power from 2x250 MW to WR grid. As per BPTA signed between JPL
and PGCIL, transfer of 500 MW power will be through long-term open access. It was also
agreed that power transfer to other than identified agencies will be affected through short-
term open access for which JPL shall approach WRLDC separately. The point of injection is
nearest ISTS connection viz. Raipur S/s. The following transmission system strengthening
was agreed:
System strengthening scheme To be executed by (i) Jindal TPS – Raipur 400 kV D/c line
including 2 Nos. 400 kV line bays at Raipur
As it is direct evacuation line interconnecting generation project with WR grid, it shall be built, owned, operated and maintained by M/s JPL. This Ckt. has since been commissioned in May 2008.
Minutes of 50th CCM held on 8th August 2008 11
System strengthening scheme To be executed by (ii) Installation of 3rd 400/220 kV, 1x315
MVA transformer at Raipur
To be carried out as an independent WR system strengthening scheme and shall be implemented by PGCIL.
(iii) Installation of 3rd 400/220 kV, 1x315 MVA transformer at Asoj (GETCO)
GETCO may review the transformation capacity augmentation requirement at their substation, if any, to effect the drawal of their allocation.
As decided in the LTOA meeting, the actual date of commencement of LTOA will be from
the date of availability of above identified transmission system as well as transmission system
of Vindhyachal_III, Sipat-I & II including signing of BPTA with POWERGRID by M/s JPL
for sharing of WR transmission charges corresponding to entire 500 MW generation capacity.
S.E.(Comml), WRPC further intimated that with the commissioning of Jindal-Raipur 400 kV
D/C line on 16th April 2008 and direct connectivity of 250 MW unit at Jindal TPS to CTU
network, its scheduling is being done by WRLDC and corresponding UI account is issued by
WRPC secretariat. At present, 2 units of Jindal TPS, 250 MW each is directly connected to
CTU network at Raipur and its scheduling and UI accounting is being done at regional level.
5.2 M/s Jindal representative stated all four units i.e. 4x250 MW at JPL are
commissioned. Out of 1000 MW capacity, Chhattisgarh State is committed to take 300 MW
power from the project while the balance power will be sold through long-term / short term
open access. He further stated that M/s JPL is also participating in bidding process for future
sale of power to various states other than Chhattisgarh in WR and States of other regions as
well. As such, he requested that the present arrangement of scheduling its generation
capacity by WRLDC and preparation of UI account by WRPC secretariat should continue.
This will also be in line with CERC order as more than 50 % power will be sold out side the
state of Chattisgarh.
In this context, representative of CSEB stated that M/s JPL have applied for only 500 MW
LTOA out of 1000 MW capacity as such its generation scheduling etc. may be carried out by
SLDC, CSEB. Representative of M/s JPL reiterated that they have committed to supply only
30% of power i.e. 300 MW to CSEB and more than 50 % power will sold outside the state of
Chattisgarh.
Minutes of 50th CCM held on 8th August 2008 12
5.3 General Manger, WRLDC stated that presently scheduling of JPL units are
being done by WRLDC and UI accounts are issued by WRPC secretariat. He opined
that same should be continued. Member Secretary, WRPC also agreed with the views of
WRLDC. However, in case committed power supply to state of Chhatigarh is observed
to be 50%, the scheduling of M/s JPL may accordingly be reviewed at a later date.
ITEM NO. 6: LTOA OF TORRENT POWER GENERATION LTD. (TPGL) 1147.5 MW (3x382.5) PROJECT AT SUGEN, GUJARAT
6.1 Superintending Engineer (Comml.), WRPC, stated that Long Term Open Access for
injection of 500 MW power into WR grid and balance to be transformed to TPSEC and
TPAEC (DISCOMs & Torrent Power) from proposed 1147.5 MW (3 x 382.5 MW) project at
Sugan, Gujarat was granted by CTU in the meeting regarding LTOA in Western Region held
on 30.09.2006. M/s TPCL had intimated that the power transfer to TPSEC would be effected
through dedicated 220 kV lines from generation switchyard itself and to TPAEC through

respectively. M/s Torrent has also signed BPTA with POWERGRID in Jan 2008.
S.E. (Comml), WRPC further stated that in accordance with CERC order dated 7th May 2008,
M/s TPGL, Sugen, 3 x 382.5 MW project falls under the control area of SLDC, Gujarat.
Accordingly, SLDC, GETCO will be responsible for scheduling, monitoring, issuing of UI
accounts, etc. as given at Item 2.1(e) above. SLDC, GETCO will furnished 15 minute time
block wise energy schedule to the concerned beneficiaries of WR to WRLDC for calculation
of drawl schedules. GETCO representative agreed to the same.
6.2 M/s Torrent Power Generation Ltd. (TPGL) representative stated that they are ready
in all aspects for scheduling their plant by WRLDC and accordingly they have installed 40
CTs of 0.2 class. However, in case the scheduling is required to be carried out by SLDC,
GETCO, then CTs of 0.2 class already installed will have to be replaced with 0.2S class to
meet the requirement of Gujarat SERC. This will amount to heavy financial burden of around
4 Crores. Further, even though M/s Torrent are ready to spend 4 Crores, the time required for
procurement and installation of CTs will be around 8-10 months.
In this context, GM, WRLDC stated that in such case, special permission for additional time
requirement for changing the CTs from Gujarat SERC might required to be taken in advance.
He further added that logistics by RLDC and different SLDCs are different in terms of class
and location etc. of CTs, PTs, CVTs, SEMs etc, and UI rates applicability and dependent on
CERC or SERC regulations applicable to region or state. He further added that the solution
to above problem could be continuing the statues quo and decision by mutual understanding
between RLDC and SLDCs.
6.3 SLDC, GETCO representative stated that Gujarat is geared up for scheduling
TPGL. Further by the time the first unit comes on bar by Nov 08 they will be fully
geared up for scheduling of TPGL. In case, there is some technical problem in
scheduling of TPGL by SLDC, GETCO, the matter may be reviewed at appropriate
time.
PGCIL representative agreed to furnish the status of implementation of system

22.2 SCHEDULING OF UNREQUISITIONED POWER FROM NTPC STATIONS IN WR TO OTHER REGION
NTPC stated that RLNG for their gas based station are being tied up considering the
anticipated requirement of power from their gas based stations. However, due to frequent
downward revision of schedules by WR beneficiaries from these stations, RLNG that is
meant for NTPC stations has been diverted to other utilities on number of occasions and
when actual requirement of power is there, the suppliers are not in a position to supply
RLNG. Due to this NTPC is facing operational difficulties and at times it becomes difficult to
operate units even at technical minimum level due to non-availability of RLNG.
In order to overcome this problem, NTPC suggested that the un-requisitioned power form
these stations may be allowed to be scheduled to the constituents of other regions at only
variable charges to enable to operate generating units fully thereby diversion of RLNG could
be minimized.
In this context, Member Secretary, WRPC stated that at present scheduling/utilization
of un-requisitioned power etc. from NTPC stations is being done in accordance with the
procedures already approved by WRE Board/WRPC. He requested NTPC to put up
this issue as an agenda item for discussion in WRPC meeting.
ITEM No.22.3: CERTIFICATION OF TRANSMISSION CHARGES THROUGH REA ISSUED BY WRPC
GUVNL representative stated that PGCIL are raising monthly invoices for claming the
transmission charges to be recovered from GUVNL. The sharing percentage used for
claiming the transmission charges in certain months is different than the percentage shown
on page no. A-4 of the REA issued by WRPC.
In this context, S.E. (Comml.), WRPC stated that M/s Jindal Power Ltd. vide letter dated
5th Aug. 08 pointed out that the % Transmission charges for which WRTS-I, PGCIL raised
the bill on them for the month of April 2008, May 2008 and June 2008 is different and is not
in accordance with monthly REAs issued by WRPC secretariat. He further stated as per the
provision under the BPTA signed by PGCIL with beneficiaries of WR, PGCIL has to raise
monthly transmission charges bill on the basis of the REA issued by WREB/WRPC.
Minutes of 50th CCM held on 8th August 2008 27
This matter was discussed in detail. PGCIL CC representative stated that the %
sharing of transmission charges indicated in the aforesaid REAs issued by WRPC
secretariat are in order. WRTS-I, PGCIL agreed to revise the bill for the aforesaid
month as per REAs. It was also unanimously stressed that PGCIL should raise bill on
the basis of REAs issued by WRPC secretariat.
ITEM No.22.4 CHANGING THE METERING POINT FOR DRAWAL OF DD & DNH THROUGH GETCO NETWORK FROM THE RECIVING END S/S OF DD & DNH TO SENDING END S/S OF GETCO
GUVNL representative stated that since the control area of GETCO is applicable to the
sending end sub-station of GETCO and the transmission losses determined by GERC for the
GETCO network are till the periphery of GETCO network, the actual drawal of DD and
DNH through GETCO network is required to be worked out for UI and REA purpose on the
basis of energy recorded by SEMs provided at the sending end sub-stations of GETCO.
In this context, S.E.(Comml.), WRPC stated that the issue raised by GUVNL need to be
examined before offering any comments or further deliberation.
ITEM No.22.5: NON-CREDIT OF DIFFERENTIAL AMOUNT BY PGCIL ARISING
ON ACCOUNT OF VARIOUS ORDERS OF CERC REGARDING REVISION OF TARIFF OF TRANSMISSION ELEMENTS
GUVNL representative stated that Hon’ble CERC through various orders has revised the
transmission tariff for various elements of transmission, which has resulted in reduction in
tariff. As such PGCIL is required to pass on corresponding credit to the beneficiaries of WR.
The following tariff orders of CERC are resulting in refund to the beneficiaries:
(a) CERC order dated 29.04.08 in petition No. 69 of 2004 for 220 kV Korba-Buddhipadar Ckt-III.
