Minutes of meeting of 27th TCC/WRPC held on 21st & 22nd November 2014 at Bhopal

MINUTES OF THE 27th MEETING OF WESTERN REGIONAL POWER COMMITTEE HELD ON 22nd NOVEMBER 2014 AT BHOPAL

The 27th WRPC meeting was held on 22nd November 2014 at Bhopal, preceded

by the TCC meeting held on 21st December 2014. The meeting was hosted by NHDC.

The list of participants of the TCC and WRPC meetings is placed at Annex 1(a) and 1(b) respectively.

The TCC meeting was chaired by TCC Chairperson, Shri Manu Shrivastava, IAS,

MD, MPPMCL. In his opening remarks TCC Chairperson emphasized the importance of

the WRPC forum, wherein all the stakeholders sit together and try to resolve the

problems, propose new ideas etc. While it is true that all of us mandatorily abide within

the framework of concerned regulations, still all problems are not resolved till new

regulations are made. Till such time, forums like the WRPC forum, constructively

address the issues framing newer methods to cope up with the challenges faced by all

of us. He cited the example of Reserve Shut Down which was formulated in the last

WRPC meeting as an attempt to address the backing down of costly generation and

simultaneously protecting the interest of all concerned stakeholders. While there was

only one attempt of the RSD in real time, due to erratic nature of the recent monsoon,

the method is still open and is featured to address the problems of low demand. He

hoped that the discussions of the TCC would resolve the problems in the present

meeting. He thanked NHDC, the host of the meeting, for making excellent

arrangements and wished a pleasant stay for all the delegates.

The TCC discussed all the agenda items of the WRPC meeting and put forth the

recommendations of the TCC discussions to the WRPC forum the next day.

The WRPC meeting was chaired by WRPC Chairman Shri I.C.P. Keshari, IAS,

Principal Secretary, Department of Energy, Govt. of Madhya Pradesh. In his opening

remarks, WRPC Chairman welcomed all the participants to the WRPC meeting held in

the ‘The City Of Lakes- Bhopal’. He informed that WR is the most disciplined region,


with a very large generation and highest demand. Many states of WR are already

supplying quality power for all day to their consumers. There is a need to maximise

generation from state generating companies. He stated that WR is the only region

where both the UMPP projects are fully functioning. There is a need to extend the URS

methodology of scheduling to these stations also and POSOCO should consider these

aspects also. The UMPP has been envisaged to have a large generation and these

problems faced by them, require to be addressed. There is a need to keep the

distribution sector financially viable. He requested all constituents to furnish data

pertaining to implementing status of the recommendations of grid disturbance

committee and also the Ramakrishna Committee report in a timely manner to the

concerned authorities. He informed that renewable energy like wind and solar have

picked up appreciably in Gujarat and Maharashtra and in MP it is catching up. The

clean energy is most welcome in the grid. However the renewable pose their challenges

pertaining to balancing and he hoped that WR shall address these mechanisms. He

thanked the host NHDC for making excellent arrangements. He thanked Member

Secretary, WRPC for meticulous follow up of the agenda items.

During the WRPC meetings, Shri K M Singh, CED NHDC welcomed the delegates. He informed that NHDC Ltd was established in the year 2000 as a joint venture company of NHPC Ltd & Govt. of Madhya Pradesh and it has created a history

by commissioning of both of its mega projects at Indira Sagar and Omkareshwar in a

record time. With total installed capacity of 1520 MW, NHDC is the largest hydro power

producer in the MP State and plays an important role in catering to the varying peaking

power demand of the MP. Both ISP & OSP are equipped with black-start facilities.

Shri S.D.Taksande, Member Secretary WRPC placed on record the immense

contributions of the following outgoing TCC and WRPC members. He welcomed the

incoming TCC and WRPC members in their place.

ITEM No.1: CONFIRMATION OF THE MINUTES OF THE 26th MEETING OF WRP COMMITTEE

MS WRPC informed that the minutes of 26th meeting of WRP Committee held on 21st

June 2014 at Pune were forwarded to the members vide letter No. WRPC/26th WRPC

Mtg./AS/2014/ 7100 dated 25.07.2014. Following comments were received on the

minutes:

1.1 Executive Director WR-II, PGCIL Vadodara vide letter no. WRTS-2/Comml/3263 dated 19.09..2014 (copy enclosed at Annexure-1.1) commented on item No. 35(III) of 26th WRPC Minutes.

The recording of WRPC on the above item was as follows:


Quote:

“WRPC decided all elements except at sl. no. 38 & 40 tabulated above were accepted

for CoD. The CoD of elements at sl. no. 38 & 40 was not agreed, therefore WRPC

decided that the above views of beneficiaries and CTU be recorded.”

Unquote

WRPC after discussions decided to modify the para as follows;

“WRPC discussed that all elements except at sl. no. 38 & 40 tabulated above were accepted for CoD. However for elements at Sr. no. 38 & 40, GUVNL/GETCO & MPPMCL/MPPTCL have not agreed for the same. The views of MP, Gujarat & CTU are recorded as above.”

Director(Opn), PGCIL expressed during WRPC meeting the view that these line layout/connections modifications are approved in Standing Committee and now going back on the Standing Committee decisions is setting a wrong example.

1.2 : WRLDC vide letter no. WRLDC/No-I/1551/2014 dated18.11.2014 have requested to modify the table and the recordings of Item No 27 of the 26th WRPC meeting as follows;

Quote:

At Sr.No.1 of the table Annual Price against WRLDC for LTSA SCADA/EMS was inadvertently mentioned as 33,326,607. The same is corrected to 33,826,607. TCC recommended for approval of Rs. 69,716,789 instead of rounded off figure of Rs. 6.9 corers.

TCC/WRPC agreed for the above modifications.

With the above modifications the MoM of 26th WRPC meeting was confirmed.

ITEM No.2: SHUTDOWN OF ISGS UNITS UNDER RSD (RESERVE SHUT DOWN) DURING LOW REGIONAL DEMAND.

Background: The removal of ISGS units during periods of low demand was discussed in 66-68 CCM meetings and 24-26 WRPC meetings. During the 26th TCC discussion


TCC chairman recommended to give a trial to RSD-RoCU(Reserve shut down-Removal

of costliest unit ) in the low demand period from July-September 2014. He further stated

that the RSD-RoCU may be limited from Mauda to Sipat during trial period. The TCC

discussed the possibilities of taking units under RSD. The major states of MP, Gujarat,

Maharashtra and Chhattisgarh agreed to RSD-RoCU trial operation in principle.

He informed that in the 26th WRPC meeting draft rules for RSD-RoCU was presented

and the principle of the draft points were acceptable to all. However it was suggested

that WRPC may incorporate suggestions if any, circulate the revised draft amongst

beneficiaries and include the same in MOM of the WRPC meeting. The set of Rules for

RSD-RoCU were framed after discussion on the drafts and the same were issued vide

letter dated 04.07.2014 and a copy of the same is attached at Annexure-2.1 TCC Discussion: Member Secretary, WRPC informed that as per the RoCU methodology the RSD was

implemented for 3 days from 17th to 19th July 2014 for Mauda Unit#2 by the nodal

agency (MP SLDC) successfully. However the RSD could not be extended due to pick

up of demand on that occasion. Further the erratic monsoon pattern this season, did not

give confidence that the demand would remain low for 3 days due to rains, and

therefore more opportunities for RSD could not be taken this year. He further stated that

this methodology may be kept open for more trials in the ensuing year. Suggestions for

refinement of the methodology, if any, would be considered after due experience of

RSD operation.

CE, SLDC,MPPTCL informed that on two or three occasions, it looked like another

opportunity for RSD was forthcoming. However since the other SLDCs could not

consent, due to erratic monsoon pattern, it could not be taken.

On behalf of TCC/WRPC MS, WRPC appreciated the efforts taken by MP-SLDC in

coordination during the above instance of RSD-RoCU.

TCC Chairperson concluded that the methodology of RSD-RoCU formulated is fine in

principle and has seen one successful implementation. However this year, it could be


implemented only once. He agreed with the recommendation of TCC to keep the

methodology open for further trials as and when situations arise in future.

WRPC discussion: WRPC appreciated the efforts taken in coordination by MP SLDC for successful implementation of the RSD-RoCU methodology. WRPC also decided that the present methodology would be continued and if required be discussed and modified as per future experience of RSD-RoCU. WRPC decided as above. ITEM NO. 3 : EXCESSIVE ADDITIONAL CHARGES AND CAPPING AMOUNT IN DEVIATION POOL ACCOUNT AFTER IMPLEMENTATION OF DSM.

TCC Discussion: MS WRPC stated that CERC vide No.L-1/132/2013/CERC dtd. 06th January, 2014 have notified the Central Electricity Regulatory Commission (Deviation

Settlement Mechanism and related matters) Regulations, 2014 and the same came into

force w.e.f. 17.02.2014. The stakeholders including MP SLDC and state utilities had

submitted their comments to Hon’ble Commission on the draft regulations.

He stated that the provisions and implementation of the above regulations was

discussed in the 24th WRPC meeting, wherein it was observed that there are many

concerns in implementing DSM and therefore beneficiaries may forward all their

concerns to WRPC. It was recommended that WRPC shall compile all the concerns on

DSM and submit to CERC for needful. Accordingly concerns received from GUVNL,

MSETCL and NTPC were forwarded to Hon’ble Commission.

He further informed that MP SLDC vide letter No. 07-05/RPC-15/3807 Jabalpur, dated

03.11.2014(copy enclosed at Annexure.-3.1) have requested WRPC to consider following points for discussion:

1. The deviation volume should be 12% of schedule or 250 MW whichever is higher.


2. The Additional charges for under drawal or over injection below 49.90 Hz frequency should not be applicable since there is a separate regulation to address the issue of congestion on account of under drawal/over injection.

3. As RRF mechanism is kept in abeyance by the Commission, the generators connected to Grid substations prior to this date have stopped forecasting their generation. Therefore, all the wind/solar Generators having collective capacity of 10/5 MW should forecast their Generation irrespective of date of commissioning of pooling station.

4. The Commission may be requested to introduce the Ancillary Services before making stringent provisions to Deviation Settlement Mechanism.

5.The Commission may be requested to introduce Real Time market Operations in the country before making stringent provisions to Deviation Settlement Mechanism.

6. The FGMO/RGMO operation was to be implemented in all qualifying Generating units by 01.01.2011, but very few units in the country have provided the facility. In absence of proper primary response it is not possible to maintain the frequency very close to 50.00 Hz, only by revising schedules.

7. The DSM violates basic principle of one penalty for single violation. If an entity under draws at frequency 50.10 Hz and above it do not get a single paisa for the entire under drawal energy, however a penalty of Rs 1.78/kwh is levied on the entire volume. The Hon’ble Commission may be requested to address this issue to avoid multiple penalties for single deviation.

8. If the infirm power is allowed to be scheduled to its procurers through the regulatory

frame work, the beneficiaries would not be unnecessary subjected to deviation because

of infirm injection.

He requested TCC to deliberate on the agenda. TCC Chairperson stated that the

problems faced by the utilities after DSM has been discussed in the last WRPC

meeting. Further MP has approached the High Court in the matter. In view of this

position he queried the need of discussing the issue again. Members requested on

seeing the present problems, now that almost six months of experience with DSM and

under different seasonal conditions has taken place.


CE-SLDC-Gujarat shared the following concerns experienced in Gujarat system post

DSM. Some of the major concerns are as given below.

(a) Renewable wind contributed to deviation March 2014 of the order of 4 % (@360

MUs) for frequency above 50.1 Hz and about 8% in 49.7 – 50.1 Hz range. In

April 14 to June 14 this was very severe and maintaining 150 MW deviation or

less was impossible for the load dispatcher. For example, on 9th May 2014, 40

blocks were violated with 1900 MW extreme variation from wind energy alone.

With the suspension of RRF mechanism from 7th Feb 2014, the wind generators

are not penalised for wrong prediction, however the state has to suffer. So

controlling deviation within prescribed limits, is very difficult.

(b) Gujarat has APL units (7-9) in which Gujarat does not have any share. However

the schedule of the units is embedded in Gujarat. With the tripping of this unit, till

4 time blocks Gujarat enters overdrawl even though all its DISCOMs are not

violating. WRLDC follows the overdrawl and in some cases message to open

lines are received. Hence to prevent that, SLDC takes action, by picking up

generation. This causes a financial burden that is extremely huge, and

unnecessary as Gujarat state DISCOMs was not violating. Further after four time

blocks, when the schedule is changed to reflect the impact of tripping, they have

picked up generation and now need to back down. Seeing + or – deviations

between two blocks of the order of 500-600 MW due to this quite common.

(c) Variations due to STOA: These schedules cannot be revised if plants trip,

causing further deviation to State.

Constituents were of the view that the charges (capping & additional charges) have

been substantially increased which is resulting in heavy penalisation to DISCOMS.

CE(SLDC) MP stated that the amount of capping and additional charges has

increased many folds, since the inception of DSM as compared to the capping and

additional charges in the UI regime.


Other major concern raised by the beneficiaries was the limit of volume set to 150 MW

or 12% whichever is less, irrespective of the utility size. Beneficiaries were of view that

the limit of volume should be w.r.t. the % of schedule and not in MW terms. A volume

limit of 10-12% of schedule would be a fair limit. There are also penalties even if the

state is helping the power system by under drawing at low frequencies.

With respect to a query, CE (SLDC) MP stated that they have filed petition with high

court and high court directed CERC to look into the matter. MP has already intimated

their views to CERC. It was also understood that Tripura has also filed a petition with

CERC.

Member Secretary WRPC stated problems faced by Gujarat and also other constituents

like MP, Maharashtra etc after DSM. However DSM has to be followed, being regulatory

in nature. So he informed that view of constituents has already been forwarded to the

Commission by MS WRPC as decided in the earlier WRPC meeting.

As a part of a solution to some of the problems faced, GM, WRLDC informed that a staff

paper on Current day exchange is issued by the Hon’ble CERC. He requested the

members to give the views so that some of the above issues can be addressed.

MS WRPC informed that that the views/concerns of constituents have been proposed

as an agenda item in the ensuing NPC meeting.

The wind forecasting is another major issue for which WRPC is working and is a part of

agenda item.

GM,WRLDC informed that the objective of DSM was to restrict the deviation from

schedule and this has been achieved in terms of energy deviation, since the deviations

by pool members across the country have reduced substantially after implementation of

the DSM regulations.


Chairperson TCC observed that since the case is pending in high court and the matter

have been proposed for in the NPC meeting, it would be appropriate to wait for the

verdict of the high court.

WRPC:

MS WRPC appraised the WRPC of the TCC discussions. He informed that matter is

also being put up to NPC agenda. Also MP has taken the matter with High Court.

Chairman WRPC suggested that since all the constituents have more or less same

grievances on the issue. 150 MW is too small a deviation and keeping it at 12% or 150

MW or higher (instead of lower) does not appear to have a major negative impact on the

grid. He suggested that if other constituents are interested and having grievances they

may like to consider joining the petition. ED, MSETCL informed that Maharashtra

Discom have filed a petition with CERC.

WRPC noted as above.

ITEM No. 4 ADDITION OF OPGW LINK AND WIDEBAND NODES IN MASTER COMMUNICATION NETWORK OF MP.

TCC: MS WRPC stated that MP SLDC vide letter No. 07-05/RPC-15/3807 Jabalpur, dated 03.11.2014 have intimated that the Master communication plan of MP is being

implemented by PGCIL, LD&C along with Master communication plan of WR. The

Master Communication plan was approved in 14th WRPC and subsequently some

modifications to the network plan was proposed and approved by WRPC in its 23rd and

26th meetings. In order to utilize the benefits of SCADA and communication by all state

utilities (DISCOMs/Generators/Transco/Holding Company) MP SLDC has taken up

additional nodes and OPGW links in Project Review Meeting of SCADA/EMS &

Communication project of WR.


He further informed that as approved in 11th and 12th Project Review Meeting,

following additional wideband nodes & OPGW links, are to be included in MP Portion of

Master Telecom project of WR.

(1) Laying of OPGW cable on 132 KV Line between 220 KV Indore SZ – 132 KV Indore

Chambal Sub Station (Approximate Distance 20 Kms)

(2) Establishment of Wideband node at 132 KV Indore Chambal Substation.

(3) Establishment of Wideband node at Shakti Bhawan Jabalpur.

(4) Establishment of Wideband node at Sub LDC Indore.

(5) Establishment of Wideband node at 220 KV S/s Bhopal.

(6) Wideband Node at Regional office of MPPMCL at Arera Colony, Bhopal.

The Wideband Node at Regional Office of MPPMCL is a new requirement and was not

discussed in PRM Meeting. However, the same shall be put up for approval in next

PRM scheduled in first week of November. MP SLDC have requested that the additional

nodes and links may please be approved by WRPC.

CE (SLDC) MP stated that the above proposal was discussed and agreed in the PRM. Member Secretary WRPC stated that since the above has been agreed in the SCADA PRM held on 12th November, 2014, and the cost would be borne by MPPTCL, the above proposal may be approved.

TCC/WRPC agreed on the above proposal of MP.

ITEM NO 05: PERMISSION ISSUE FOR OPGW LAYING ON RELIANCE LINES AS PART OF MASTER COMMUNICATION PLAN:

5.1 Back ground : PGCIL vide email dated 07.10.2014(copy enclosed at Annexure-05) intimated that implementation of Master Communication plan to connect Central


Sector Substations & Power Plants and some of STU substations was approved in the

14th WRPC meeting. Additional requirement to be implemented under the Master

Communication plan was also approved in the 21st WRPC meeting.

As per approval of SCADA O&M committee, the connectivity to Kolhapur and Solapur

substations of POWERGRID is to be provided by installing OPGW on Parli-Solapur and

Solapur-Kolhapur lines owned by “Reliance Power Transmission Limited”, as there is no

other suitable route available. This would also ensure connectivity of Goa SLDC and

Mapusa substations of POWERGRID to WRLDC. At present there is no fiber

connectivity between Goa SLDC and WRLDC.

POWERGRID has taken up with “Reliance Power Transmission Limited” for their

permission to install OPGW on their lines vide letter dated 17.01.2013, 31.01.2013,

11.03. 2013 and 8.05.2013. Reliance in their response has raised the issues such as

payment of tariff on removal of earth wire, insurance, mortgage of assets and

maintenance etc. and has requested WRLDC to discuss this issue in the SCADA

committee.

As the installation of OPGW has the approval of SCADA committee and WRPC,

Reliance was informed accordingly. Considering the Reliance’s reservations certain

changes were proposed in the Master Communication Network of WR in 25th WRPC

which were also approved.

Subsequent to approval of 25th WRPC, the following shortcomings are noticed in the

communication network.

(i) Pune 400KV substation of POWERGRID cannot be connected with Fiber as

part of the line originating from Pune 400KV substation of POWERGRID

(LILO of Lonikand-Kalwa) belongs to Reliance.

(ii) Pune 765 KV substation of POWERGRID can not be connected with fiber

unless Solapur-Aurangabad (756KV) line of PG is completed i.e. by 2016.

Even on completion of this link the alternate path would not be possible.


(iii) Redundant connectivity to Goa SLDC, Kolahapur 765 &400KV, Mapusa

400KV Substations of POWRGRID would not be possible. The connectivity

in one direction to these locations is being provided through Southern Region

through Kolhapur-Narendra Line.

Therefore, in order to provide the fiber connectivity to Goa SLDC, Mapusa

400KV, Pune 765KV and Pune 400KV substations of POWERGRID in two

directions, it is essentially required that the OPGW is laid on following lines of

Reliance.

(a) LILO portion of Lonikand-Kalwa Line at Pune 400KV substation of

POWERGRID (Part of this line belongs to Relaince)

(b) Pune 765KV-Pune 400KV line of Reliance

(c) Solapur400KV-Kolapur 400KV lines.

(d) 400 kV solapur-parli

The above transmission lines of Western Region Power transmission Company

(Maharashtra) Ltd (Subsidiary of Reliance Power Transmission Limited) (IPTC) have

been implemented as per Power Transmission Agreement dated 03.03.09 signed by the

beneficiaries. As per agreement clause 4(iv), the terms and conditions for use of IPTC

lines for installation of OPGW are to be discussed and agreed upon subject to

regulation framed by CERC. It may be mentioned that CERC tariff regulation for block

year 2014-19 has the provision for recovery of tariff for communication system also.

Since the installation of OPGW on the above mentioned lines of Reliance is essentially

required for meeting the communication requirements of RLDCs and NLDC for Grid

operation, the terms and conditions for installation of OPGW on above lines may be

finalized by WRPC and Reliance Power Transmission Limited may be asked to install

OPGW on their above mentioned lines.

MS WRPC stated that the matter was discussed in the 68th CCM and the recommendations of the sub-Committee are as follows:


1. RETL did not have any objection to technical requirement of laying OPGW for

grid requirement.

2. RETL proposed that they are ready to own OPGW asset. However considering

urgent requirement, they are willing to give turnkey work to PGCIL for installing

OPGW and reimburse the cost to PGCIL. This would imply change in project and

corresponding change in tariff for which if beneficiaries agree, then RETL may

approach CERC.

3. EE(GUVNL) did not recommend owning of asset by RETL due to change in tariff

, as the project was awarded to RETL through competitive bidding and changing

of tariff was not desirable and he proposed that PGCIL shall install and own the

asset and Earth wire be retained by RETL. Hence the tariff of project shall not

change.

4. RETL pointed out that the Earth wire retention is not possible by them and

modalities of retention of Earth wire by PGCIL are required to be framed, also

removal of earth wire shall not result in any tariff change. Hence beneficiaries

and lenders shall have to approve even if the asset are to be owned by PGCIL.

5. CCM recommended that there is an urgent need for installing OPGW and matter

may be put up to TCC/WRPC for discussion.

TCC discussions: TCC discussed the issue and decided that a small group would discuss the modalities

and put up same to WRPC.

The group, after discussions suggested the following models to WRPC for decision.

Model-I: OPGW for the project shall be owned by RETL and project implemented by PGCIL on

deposit work basis and cost paid by RETL. In case PGCIL cannot implement the project

then RETL would implement the project.


RETL was agreeable to one time recovery of fixed cost of OPGW or recovery by tariff

approved by CERC.

Fixed cost of line would remain the same even after removing earth wire.

Model II: OPGW for the project owned by PGCIL and recovery of cost for OPGW shall be by tariff

approved by CERC. For this option Line usage cost was demanded by RETL and it

was not acceptable to beneficiaries as nowhere this practice is done and this incident

shall open many such cases. The demand of protection of availability of RETL lines due

to OPGW was acceptable to all beneficiaries. RETL shall get full availability of line, if

there are problems arising due to OPGW. Beneficiaries were also acceptable to fixed

cost of the RETL line project remaining same even after removal of earth wire.

RETL representative desired to inform his management that no charges for line usage cost would be possible.

WRPC discussion: MS WRPC stated that Model –I suggested in the group meeting was acceptable to all. Director (O) POWERGRID informed that it shall not be possible for PGCIL to implement the project in case of Model-1. Further he informed that he had discussed the issue with CEO RETL and CEO RETL has agreed for installation and ownership of OPGW by POWERGRID, as given in Model-2. WRPC asked PGCIL to talk with CEO RETL, (in view of the different position given by RETL in TCC) and confirm to RETL’s agreement for Model-2. In case the confirmation is received, Model-2 can be taken up for implementation. WRPC noted as above.


Subsequently POWERGRID informed that matter was discussed with CEO, RETL and

broadly following points were agreed by RETL on the above matter. The same were

confirmed by POWERGRID vide letter dated 02.12.2014(Copy is enclosed at

annexure-5.1) (i) POWERGRID shall lay the OPGW on Reliance transmission lines.

(ii) The earth wire dismantled from the line shall be returned to Reliance.

(iii) OPGW shall be the property of POWERGRID and the tariff shall be in line

with ULDC charges.

(iv) The tariff of Reliance shall not be reduced because of removal of Earth wire.

(v) Non availability of transmission lines due to OPGW related outage shall not

be on Reliance account.

(vi) No ROW charges shall be payable to Reliance.

In view of POWERGRID’s written confirmation, Model-2 of ownership of OPGW by

PGCIL can be accepted, subjected to confirmation of MoM in the next WRPC

meeting.

ITEM NO 06: NON SUPPLY OF REQUIRED DCD TO NTPC, SIPAT, BY POWERGRID.

6.1 Back ground : WRLDC intimated vide letter dated 10.09.2014 (Annexure-6) NTPC, SIPAT are facing problem in sending weekly SEM data to WRLDC due to non

availability of enough DCDs. Many requests were made to Bilaspur S/S of

POWERGRID by NTPC, SIPAT and WRLDC. SIPAT is yet to receive the required DCD.

Similar problems were reported from other locations also.

WRLDC informed that POWERGRID is not able to provide required DCDs to stations

due to non availability of the same with them. Since implementation of AMR may take

some time, it is proposed that POWERGRID may procure required DCDs so that the

weekly data transfer to WRLDC will not be effected due to failure of DCDs.


6.2 : MS WRPC stated that the matter was discussed in the 68th CCM. CCM members pointed out that regularly PGCIL proposals for ABT meters; DCD’s etc including spares

has been approved by WRPC immediately without any hesitation. In view of this, PGCIL

not able to meet the demand of these DCD’s is un-understandable. PGCIL may

therefore explain the policy of meters, spares, DCD’s etc followed by them and how

they propose to remove the difficulties faced by WRLDC in sending weekly data, at

ensuing TCC/WRPC meeting

WRPC/TCC discussions: WRPC requested POWERGRID to ensure that the spare DCDs are available and such issues are planned appropriately and resolved in timely manner. POWERGRID agreed for the same.

ITEM.NO.7: ITEMS FROM 37th SCM OF WR :

MS WRPC informed that following schemes were agreed in the 37th SCM for WR held

on 05.09.2014. The (A) item pertains to sharing of cost following the proposed shifting

of Kahalgaon Stage I and II to curtail short circuit levels at Kahalgaon. The details are

given below:

A) SPLITTING OF KAHALGAON STPS STAGE I AND STAGE II :

A-1) Discussions in the 37th SCM a) Kahalgaon STPS generation project of NTPC in Eastern Region has an

installed capacity of 2340 MW (Stage–I: 4X210 MW, Stage–II: 3X500 MW). In

Stage-I, the constituents of ER, NR and SR have power allocation and in Stage-II

constituents of ER, NR and WR have the power allocation. Standing Committee

on Power System Planning of ER, in its meeting held on 20.09.2010 has agreed

the bus splitting scheme at Maithon, Durgapur, Kahalgaon and Biharshariff

substations in Eastern Region to contain fault level at these substations. The

estimated cost of the scheme of bus splitting of Kahalgaon STPS Stage-I and

Stage-II, to be implemented by NTPC is about 98.94 crores. The scheme was


approved by ERPC in its 24th meeting held on 27.04.2013. The scheme has

been approved by NR in their 29th NRPC meeting and 26th TCC meeting held on

13.09.2013 and 12.09.2013 respectively. The scheme was taken up for

discussion in the 24th WRPC/TCC meeting held in Oct., 2013, wherein, it was

suggested that scheme should be first taken up for discussion in the Standing

Committee meeting of WR.

During 37th SCM as regards to the high cost of bus splitting, NTPC stated that

the implementation of bus splitting arrangement in generating switchyard is more

complex in nature as compared with that of sub-station. In the present case,

scheme envisages operation of Kahalgaon as two electrically independent power

stations each with a separate station power supply system as well as rotating

auxiliaries’ safety. He added that various packages of the scheme are ready for

award and requested for the approval of the scheme.

After further deliberations, the scheme was agreed by the members of 37th SCM.

Regarding the apportionment of the cost of implementation of the scheme

between Kahalgaon Stage-l and Stage-II, WR constituents were of the view that

the same should be on the basis of installed capacity of Kahalgaon Stage-l and

Stage-II.

A-2) MS WRPC stated that the matter was discussed in the 37th SCM held on 05.09.2014, in view of the comments forwarded by WRPC in this regard based on the

decision taken in the 24th WRPC meeting. In the 24th WRPC meeting WR constituents

were not in agreement with the ER constituents’ contention of sharing of the cost of

scheme between Kahalgaon Stage-l and Stage-II in ratio of their annual fixed cost as

agreed in the ERPC meeting. But they were of the view that as per CERC regulation in

vogue, the cost should be apportioned in the ratio of installed capacity.


A-3) TCC discussions:

During TCC discussions, WR beneficiaries retained their stand of sharing the cost of splitting the bus on Installed capacity basis, since this is as per the CERC regulations. It was decided that WRPC secretariat would propose this agenda item for discussion in the ensuing NPC, as there are different views (based on annual fixed cost by ER and as per installed capacity by WR beneficiaries). It was also suggested that NTPC shall put up the above views of WRPC before CERC during filing of tariff.

WRPC agreed to TCC recommendations.

B) PROCUREMENT OF ONE NO. 333 MVA, 765/400 KV AND TWO NOS. OF 500 MVA, 765/400 KV ICTS FOR WESTERN REGION – POWERGRID PROPOSAL:

MS WRPC informed that following issue pertaining to procurement of one 333 MVA,

765/400 kV ICT and two 500 MVA 765/400 kV ICTS for WR was taken up in 37th SCM

as given below. (The TCC/WRPC discussions for items(B), (C) and (D) below are taken

after D . )

Discussions of 37th SCM for WR : Director (SP&PA), CEA stated that at present seventy two (72) units of 500 MVA, 765/400 kV single phase ICTs and twelve (12) units

of 333 MVA 765/400 kV single phase ICTs are under operation at various 765/400 kV

substations in Western Region.

He added that each of the above sub-station has one single phase unit as spare. These

transformers are manufactured outside India at works of ABB, Hyundai, BTW and

Hyosung. If any of these units fails, it has to be transported to off shore works of

manufacturer for the repair, which is a time consuming process. During the repair

period, failure of second unit may lead to overloading of the other units operating in

parallel and may cause transmission constraint. In view of above, POWERGRID has

proposed to procure two (2) nos. single phase 500 MVA capacity and one (1) no. single


phase 333 MVA capacity 765/400 kV ICT as spare for Western Regional Grid. The

issue was also deliberated in the 35th meeting of Standing Committee on Power

System Planning in WR, wherein the proposal was not agreed by the WR constituents

and POWERGRID was requested to give priority to periodic maintenance and

monitoring of these ICTs.

GETCO and MSETCL were of the view that POWERGRID can procure the spare

transformers as a part of their inventory but the constituents should not be burdened

with the additional tariff on account of capital investment made in spare transformers.

(C) PROCUREMENT OF SPARE 765 KV REACTORS FOR WESTERN REGION – POWERGRID PROPOSAL. MS WRPC informed that following issue pertaining to procurement of 765 kV spare

reactors for WR was taken up in 37th SCM as given below.

Discussions of 37th SCM for WR : Director (SP&PA), stated that POWERGRID has informed that at present six (6) units of 765 kV, 110 MVAR single phase reactors and

one hundred two (102) units of 765 kV, 80 MVAR single phase reactors are under

operation at their substations in Western Region. The voltage at 765 kV buses in WR is

generally high and failure of any one unit of the reactor may lead to over voltage in the

system. POWERGRID has proposed procurement of one unit of 765 kV, 110 MVAR

single phase reactors and two units of 765 kV, 80 MVAR single phase reactors as spare

reactors for Western Regional Grid.

D) PROCUREMENT OF SPARE 125 MVAR, 400 KV REACTORS FOR WESTERN

REGION –POWERGRID PROPOSAL. MS WRPC informed that following issue pertaining to procurement of 400 kV spare 125

MVAR reactors for WR was taken up in 37th SCM as given below.


Discussions of 37th SCM for WR : Director (SP&PA), stated that POWERGRID has informed that at present ten (10) units of 400 kV, 125 MVAR reactors are under

operation and fifteen (15) units of 400 kV, 125 MVAR reactors are under various stages

of commissioning at their substations in Western Region. The voltage at 400 kV buses

in WR is generally high and failure of any one unit of the reactor may lead to over

voltage in the system.

POWERGRID has proposed procurement of two unit of 400 kV, 125 MVAR reactors as

spare reactors for Western Regional Grid.

To improve the reliability, members of the Standing Committee agreed with the

proposals at B), C) and D). However, suggested that commercial implication of the

scheme may be deliberated in WRPC forum.

TCC discussions:

With respect to procurement of spares, Beneficiaries were of the view that maintaining

healthiness & reliability of transmission elements and required inventory is responsibility

of PGCIL. Also the system has been planned keeping some inherent contingencies.

Therefore PGCIL may procure the spare ICTs and reactors at B, C & D either through

PSDF fund or through their own expenditure.

CTU representative informed that all other Regions(ER/NR) have already agreed for

similar proposal in their region. He further stated that in case of failure of ICT or

reactors, it takes considerable time to repair/procure the same and therefore the

reliability is sacrificed for such period. He requested beneficiaries were requested to

review their stand on above in the interest of the reliability and quick replacement of

faulty equipment.

WRPC Discussion: Director, POWERGRID stated that there is a need to have adequate spares to meet

n-1-1 contingency. Simultaneous outage of two 1-ph units may lead to large scale (1000


MW to 1500MW) evacuation constraint. WR Beneficiaries reiterated the view that

maintaining healthiness & reliability of transmission elements is responsibility of PGCIL.

WRPC noted that beneficiaries were not agreeing to bear the expenses of spares under items (B to D) and since responsibility of maintaining healthiness and reliability is the responsibility of POWERGRID, PGCIL may suitably decide on procurement of spares or otherwise as beneficiaries would not be sharing the cost of spares.

ITEM NO. 8 : LOAD FORECASTING IN WESTERN REGION

TCC: MS WRPC informed that as per the amended DSM that is effective from 17th February 2013 the SLDCs, SEB, distribution licensees shall always restrict the net

drawal of the State from the grid within the drawal schedule keeping the deviations from

the schedule within the limits specified in the Deviation settlement mechanism

regulations. Therefore it is imperative that adequate attention may be paid towards load

forecasting. The matter was discussed in the 455th and 456th OCC as well as in the

25th TCC/WRPC board meeting wherein it was decided to create a task force for

exploring development of a software for load forecasting. SLDC GETCO was nodal co-

ordinating agency for the same.

a) In the 26th WRPC meeting, CE, SLDC GETCO informed that DISCOMS had

prepared proposal. Five load forecasting service provider companies (FSP) had

come forward to forecast the load on trial basis for three months. The same shall

be done free of cost for three months. Pilot projects can commence from July

2014 for three months. Upon successful completion of trial run of forecasting,

commercial offers can be taken up.


b) A meeting was held on 03.04.2014 at Mumbai and (SLDC) GETCO, Gujarat was

nominated as nodal agency for implementation of the load forecasting in WR.

Participants agreed that at least two DISCOMs from each state should participate

in pilot project of Load Forecasting. Second meeting on Load Forecasting was

held on 11.06.2014.

c) CE,SLDC GETCO informed the updated status on the pilot project is as follows ;

(i) MP has already awarded contract for load forecasting and the same is expected to be available by year end. Therefore MP will not participate in the present scheme. The pilot project will start functioning from December 2014.

(ii) Chhattisgarh had requested for copy of NDA and same was forwarded to them. Their work is under progress.

(iii) Maharashtra SLDC, conveyed that Maharashtra DISCOMs response is awaited. BEST & TPC is already having such forecasting system in association with IIT-Bombay. SLDC Maharashtra representative informed that data exchange with IIT Bombay will be completed by October 2014 end.

(iv) Due to non availability of coordinator details of GOA, it is not possible to contact them. M/s. Marcadose, load forecasting service provider, has not received any response from Goa.

(v) IIT, Gandhinagar load forecasting service provider for DD & DNH, has not received any response from DD & DNH

CE, SLDC GETCO requested any beneficiary facing any problem with respect to load forecasting in the above pilot project may contact them for any assistance required.

WRPC noted as above.

ITEM.NO.9: IMPACT OF TRIPPING OF UNIT (S) IN APL STAGE-3 ON

GUJARAT:

Back ground : GETCO vide letter SLDC/CE/MIS/27th WRPC-Agenda/T-3401 dated 31/10/2014 have intimated that SLDC-Gujarat is looking after scheduling of 1980 MW (3 x 660 MW units No. 7, 8 & 9 of M/s. APL, Mundra) in which State Discoms have no


share. Even if any of these units trips, there is substantial over drawl at State periphery which attracts penalty for no fault of any of the State entities.

CE SLDC (GETCO) stated that SLDC-Gujarat has to resort to picking up even costly gas based generation or load shedding by a substantial quantum which is not at all in the interest of the consumers of the State. In some cases, WRLDC had initiated actions for opening of EHV lines without waiting for the effect of actions taken by SLDC in the form of picking up generation or resorting to load shedding. He further stated that whenever APL revises the schedule in case of tripping of unit in Stage-3, sudden effect of around 400 to 500 MW change in schedule in one time block is given by WRLDC. At this moment there is a heavy under drawl at State periphery. It attracts penalty on account of under drawl.

He presented the impact of tripping of APL unit No. 7 on 08.03.2014 19:56 hrs which has resulted in huge over drawl and subsequent revision of Haryana schedule after four time blocks resulting in huge under drawl. SLDC-Gujarat has to pick up (soon after tripping of unit to curb over drawl) and back down the State generation (when the schedule is revised from 4th time block) by around 500 MW within one hour to maintain deviation within specified limit.

He further stated that SLDC had taken up the matter with WRLDC for smooth changeover of control area of APL Stage-3 from SLDC Gujarat to WRLDC in homogeneous interest of Western Region and requested that the above matter may be deliberated to find out amicable solution.

TCC discussions:

MS WRPC briefed TCC on the above position. CE (SLDC) GETCO stated that tripping

of large size units(7,8,9) at APL stage-III results in deviation as described above, over

and above this WRLDC is issuing notices to GETCO for deviations during such

occasions. Since Gujarat is not responsible for the deviation and schedule from this

stage is to other beneficiaries out of WR, hence control area of APL stage-3 (7,8,9)

should be with WRLDC.


MS WRPC opined that stage wise control area for generating station is not permitted in

the existing clauses of IEGC, therefore control area of complete station can either be

transferred to WRLDC or the control can be retained by GETCO. TCC agreed to the

view of MS WRPC. WRLDC queried when the deviations by Gujarat (due to tripping of

APL units) are passed on to APL .What is the problem?

GETCO representative informed that the provisions/principles of deviation regulation of

GERC is still as per old UI and different from the CERCs DSM and therefore the

deviation charges applied to Gujarat through DSM are different & much higher than

those passed on by Gujarat to APL. He further informed that the GERC UI regulations

are due for notification in short time, in line with CERC DSM regulations. He informed

that even after DSM of state is in line with centre, the problem persist because WRLDC

follows Gujarat for four time blocks when deviation is yet to be revised due to tripping.

WRPC:

Committee appreciated the problem faced by Gujarat. However WRPC decided that Status quo as regards to control area of APL Mundra shall be maintained. Any change in the same can be taken at NPC/ National level meeting since the present decision to maintain control area with GETCO was taken at National level meeting due to some of the stake holders in CGPL being outside WR.

ITEM.NO.10: ALLOCATION OF URS FROM CGPL UNITS: TCC : MS WRPC informed that GETCO vide letter SLDC/CE/MIS/27th WRPC-Agenda/T-3401 dated 31/10/2014 have intimated that at present, all the Central and State generating stations are governed by the tariff regulations of the respective commissions. CE SLDC Gujarat informed that in case of Central Sector NTPC stations, its beneficiaries are allowed to avail the un-requisitioned quantum surrendered by one beneficiary (ies) to another beneficiary (ies) of the same power station on the requisition by any of these beneficiaries desiring to avail it. In case the original beneficiary requests


back for its share of power, then its schedule and schedule of beneficiary who had availed URS power would be revised.

He stated that the URS of NR constituents in CGPL is not being scheduled to Gujarat in line with the above procedure when there was acute shortage of power. The aim behind the reallocation of URS is to utilize resources in the best possible / in an optimum way and therefore requested that the issue of allocation of URS from CGPL in line with other Central Sector NTPC units may be discussed.

TCC Chairperson stated that the issue can be discussed so that some fruitful decision can be arrived. The discussion however could not converge. Following are the main points raised by WRLDC:

1) WRLDC made a presentation on as to why, in their opinion, URS for CGPL or other than NTPC station is not allowed citing the CERC order dated 11.01.2010 in petition 134/2009 & IA 54/2009 and various provisions of IEGC. GM, WRLDC informed that in case of Sasan which a project under section 63, whether the provisions of the judgement under section 62 for NTPC stations for URS case can be applied. Hence WRLDC had requested them(Sasan) to go to CERC. TCC Chairperson replied that the URS order does not gain strength from the project being under Section 62 but from the merits of the case of URS. These merits/grounds are also applicable to Sasan or CGPL.

2) WRLDC also informed that they do not have objection to URS but certain transmission issues are there that requires clarification.

3) WRLDC informed for NTPC stations, the allocations are deemed LTA. This is not the case for others.

4) The issue comes how to account URS from these stations as LTOA, MTOA or STOA transaction. If it is STOA it can be permitted as per available regulatory clauses.

5) WRLDC were of the opinion that such URS transactions even within the WR beneficiaries cannot be taken up, except under STOA.

The main points of the beneficiaries were:

1) Beneficiaries can always schedule URS power through STOA from any station, for which they do not require any support/suggestion from WRLDC. However


they are the of the view that scheduling of UMPPs is done on the same line and regulatory framework as is done in case of Central Sector (NTPC) stations and therefore scheduling of URS power from these stations (UMPPs) should be allowed on same terms and conditions of Central Sector (NTPC) stations.

2) If beneficiaries within WR want the power from these stations in URS, the same should be permitted, at least to begin with, within the region

WRPC:

Chairperson WRPC observed that CERC or for that purpose any judicial body gives verdict on the prayer made by the petitioner before them. Therefore in the case of petition 134/2009 & IA 54/2009, CERC has given verdict on the prayer made by the petitioner and therefore the verdict should not be read in isolation. The WR beneficiaries are arguing that there is a similarity in scheduling of UMPPs and Central Sector (NTPC) stations and therefore scheduling of URS power in UMPPS should also be allowed. Regulations and CERC orders are therefore required to be read in the proper prospective and relevant provisions put together in Unison.

Chairperson WRPC informed that the petition of URS with Sasan will take its time to be resolved by the Hon’ble Commission. However meanwhile there are numerous instances where URS can be availed with these two existing and working UMPP in the WR for which we must consider doing something in the interim period. TCC Chairperson pointed out that with these two UMPPs, there are situations where beneficiaries in NR surrenders and beneficiaries of WR want power. These do not involve transmission constraints in general, but in the reverse case when NR beneficiaries may want it, there could be transmission constraints issues.

Chairperson WRPC suggested that beneficiaries may file an IA/petition with CERC seeking URS from these stations as is done in case of NTPC stations for the interim period, without applying STOA charges. Subject to outcome of Sasan UMPP petition, if required as per judgement retrospectively STOA charges can be settled. This gives advantage of utilising URS from UMPPs in interim period.

WRP Committee noted as above.


ITEM No.11: IMPLEMENTATION OF AUTOMATIC METER READING IN WESTERN REGION

TCC: MS WRPC stated that the matter was discussed in 66th, 68th CCM, 23rd and 26th WRPC meeting. In the MoM of 23rd WRPC meeting held on 12th July 2013 at Silvasa,

it was recorded under item no.26-C that, “ recurring cost be included in the fees and charges of WRLDC ”. WRLDC had requested to drop the above text and item 26-C and last para may be replaced with the following

"The provision for recovery may be taken up in appropriate technical/ commercial forum

for further submission to WRPC for approval"

MS WRPC further stated that the matter was discussed in the 68th CCM and the sub-

Committee was of the view that the MOM of the 23rd WRPC need not be amended. The

sub-Committee agreed to the views of WRLDC that there was no provision for recovery

of these recurring charges of AMR under fees & charges head of WRLDC. Therefore

CCM recommended that the one time capital cost may be recovered (as in the case of

ABT meters by PGCIL) and the recurring cost may be recovered in the O&M charges by

PGCIL.

Beneficiaries retained their stand expressed in the 68th CCM.

POWERGRID representative stated that in case of AMR project the recurring cost is

substantially high and they would come out with a way of addressing recurring charges

in the next CCM.

WRPC in principle accepted the TCC recommendation of recovery of recurring cost should be done through O & M expenses. POWERGRID may give its method regarding recovery of recurring charges (in the forthcoming CCM).


ITEM NO. 12: REPORT OF THE TASK FORCE ON POWER SYSTEM ANALYSIS UNDER CONTINGENCIES HEADED BY SHRI V. RAMAKRISHNA:

TCC: MS WRPC stated that as a follow-up of the recommendations of Enquiry Committee headed by Chairman, CEA on grid disturbances of 30th and 31st July 2012

that took place in NEW grid, Ministry of Power, constituted a “Task Force on Power

System Analysis under contingencies in Dec 2012”. The Task Force was headed by

Shri V Ramakrishana Ex-Member (PS), CEA New Delhi. The terms of reference broadly

covers analysis of the network behaviour under normal conditions and under

contingencies, review of operation philosophy of protection relays, islanding schemes,

technological options to improve the performance of the grid etc. The brief on the report

is enclosed at Annexure 12 :

He further stated that the report along with its recommendations was discussed in the

122nd PCM. He requested SE(C & P) WRPC to give a presentation on the Task Force

report and its recommendations

SE (C & P) WRPC made a presentation on the Task Force report and its

recommendations vis a vis how WR utilities stands as regards to the recommendations

of the Task Force report.

He elaborated the recommendations of the Task force, pertaining to protection &

system studies and informed that the following action plan was recommended by PCM

in line with the Task force.

1) Formulation of Special groups for studies and protection co ordination.: The above report mentions the need to form specialized groups to study the

system studies, protection, control and stability, identification and training of man

power, etc. PCM recommended that the existing study group and protection

groups would interact and come up with suggestions to implement the

recommendation. PCM recommended that a small group would assess the


requirements in various areas and suggestions would be examined in a special

meeting.

2) Contingency and Stability Studies : a) A study group would be formed at regional level to assess the feasibility of

carrying out real time studies at WRLDC & SLDC requires to be examined in

view of difficulties faced in the SCADA data & accuracy.

b) PCM recommended that the study group shall continue to carry system studies

at regular intervals.

3) Islanding Schemes:

PCM felt that the existing islanding schemes in WR are in line with the

recommendations of the report. WR has therefore complied with the same.

Regarding new islanding schemes under discussion the same shall be formulated as

per the recommendations.

4) Transmission Operational Planning Criteria :

This issue pertaining to restricting dispatches are under review by National Reliabilty council for Electricity formulated under Chairmanship of Member(GO&D), CEA, New Delhi.

5) Frequency Regulation :

The issue is being addressed at national level.

6) Integration of Renewable Energy in the grid:

The issue is being addressed at national level.

7) Controlling High Voltages in grid during periods of low line loadings:

The issue is regularly being reviewed in the OCC.

Low Voltage problem: Planning for application of STATCOM, SVC and other dynamic Var support for better voltage stability, is being addressed by Standing Committee. WR region is not facing acute low voltage problem in the last few years .


Operational criticalities prevailing in grid requiring attention of load dispatcher :

This issue pertains to NLDC.

Import limit for Northern Region for July 2013 :

Not Applicable to WR.

Operation of Mundra- Mahendragarh HVDC link :

Already implemented.

Data Telemetry and Phasor Measurement :

Already being implemented under URTDSM .

Reactive support by generators for maintaining proper Voltage profile in the grid :

This aspect is regularly reviewed in the OCCMs.

8) Tuning of power electronic devices & PSS:

WR has already implemented PSS tunning on 29 generating units in the PSS tuning

initiative. However PCM recommended review of this activity, in view of generation

addition and change in system configuration. Regarding HVDC controllers and

TCSC tuning, the same requires to be taken up by the group to be identified at

Sr.No.1

9) Review & correction of relay settings :

a) PCM reviewed the philosophy of protection and observed that the WR protection

settings are mostly in line with the recommendations. However issues pertaining

to Zone-3 relay settings & its coordination with the Lower voltage level

protections would arise if the Ramakrishna Committee recommendations (time

grading & no compromise on the reach) are to be implemented. PCM felt that

the issue is of very complex nature, requiring tricky coordination and case to


case coordination and requires specialized study possibly involving consultants.

However PCM observed that the existing Zone-3 settings in WR with DEF

backup is found to operate satisfactorily as such protection is not sacrificed.

Hence switch over to the new philosophy (time grading & no compromise on the

reach) may be done only after adequate studies.

b) PCM recommended that the protection audits in future shall be carried out as per the guidelines and formats as given in the recommendations.

WRPC appreciated the fact that WR utilities/constituents by and large are compliant with the recommendations of the Task Force report. Committee noted the recommendations of the Task Force report and suggested to pursue the action plan as discussed in TCC.

ITEM NO 13: COMMISSIONING OF NEW SYSTEM PROTECTION SCHEMES IN CONNECTION WITH SYNCHRONIZATION OF SR AND NEW GRID:

TCC: MS WRPC stated that the activities associated with the synchronization are being periodically monitored by the Central Electricity Authority and the Ministry of Power.

Commissioning of certain identified System Protection Schemes was one of the prerequisites

for synchronization. The details of the SPS to be implemented in Western Region and the

actions to be taken by different utilities were elaborated vide WRPC letter

WRPC/Protection/SPS/2013/2046 dated 29.11.2013 to all the concerned.

He further informed that concerns regarding the backing down quantum and inclusion of more

generators in the backing down of generations under various schemes were raised by the WR

constituents in the 120th PCM and 25th WRPC meetings. Accordingly WRPC vide letter dated

25.02.14 took up the issue with NLDC including other technicalities involved in the schemes.

NLDC vide letter dated 11.04.2014, forwarded the revised proposal for various SPS related with

765kV Solapur-Raichur circuit. A meeting was held on 29.04.2014 to discuss the above

proposal and the backing down quantum for generators in WR finalized for various security


threats in the. The matter was further deliberated in the 26th WRPC meeting held on 21.06.2014

and NLDC was in agreement to enhance the limits and introduce time delays immediately as

suggested in the scheme. As and when the signals are extended to the newer generators the

quantum of backing down of the already participating generators be reduced on prorate basis.

PGCIL informed that the signals have been extended to all the new generators identified except

Lanco Amarkantak (due to change in system configuration).

MS WRPC stated that in the 122nd PCM, it was suggested that WRLDC may take up the issue

with the generating stations for wiring up of the signals for the backing down. After completion

of wirings mock testing of the SPS would be carried out by WRLDC and the SPS would be

commissioned at these new generators.

MD MSETCL stated that concerns have already been raised by MSETCL over the SPS and a

petition has been filed in CERC, since MSETCL/MSEDCL is the major sufferer due to frequent

operation of the SPS. He further stated that CERC has referred the matter to CEA for further

studies and their views on the SPS. Accordingly CEA conducted studies and the results and

findings were forwarded to MSETCL for comments. MSETCL have forwarded their comments

and suggested that the data considered for the study case is not as per their estimates.

WRPC observed that the SPS should be designed by considering the comments of the utilities involved. It further decided that WRLDC shall coordinate for extending signals to generators and testing of SPS on non-trip mode.

ITEM NO 14: IMPLEMENTATION STATUS OF SPS UNDER PROGRESS:

14.1) Revised Changes in SPS at CGPL Mundra:

MS WRPC informed that the revised SPS(after the occurrence of 12.03.2014) agreed in the

26th WRPC meeting is as follows;


(i) If export is more than 3100MW and any one line out of eight lines trip – reduce generation in

two units to the tune of 800MW.

(ii) If second line trips immediately in addition to (i) –trip one unit immediately.

CGPL have informed that the revised SPS has been implemented.

14.2) SPS at APL Tiroda :MS WRPC informed that a special meeting was convened by WRPC on 22.08.2014 to review the SPS at APL Tiroda in view of expected

synchronization of 5th unit of APL Tirora and likely scenario of the flows and

commissioning of the transmission system associated with APML.

The contingencies required to be considered and the actions suggested for the SPS are as

follows:

1) Loss of 765kV Tiroda-Akola2 S/C : In this case, APL would backdown the generation to

2200MW ex-bus, through mill trip and control valve closing. Further manual generation

backing down as per instructions of MSSLDC, if felt necessary. The logic for detection of

loss of 765kV Tiroda-Akola2 S/C should be appropriately implemented by APL, to

accommodate tripping of 765/400kV ICT at Akola2 also and the time delay for initiation of

backing down after detection of loss of 765kV Tiroda-Akola2 S/C shall be kept below 1

sec.

2) Loss of 765kV Tiroda-Akola2 S/C and subsequent loss of 400kV Tiroda-Warora S/C:

APL would bring down the ex-bus generation to a level of 1100MW. The time delay for

initiation backing down after detection of the above contingency shall be kept 600 msec.

(Note: The time delays in both contingencies were introduced only to ensure that false tripping/backing down of units are avoided under transient conditions).


3) The already approved SPS schemes for APL Tiroda (agreed SPS scheme between

MSETCL & APL as intimated vide letter MSLDC/Tech-SO/1198 dated 01st July 2014,

NLDC SPS) beyond Wardha and Akola shall remain unchanged.

Therefore various SPS’s at APL Tiroda are as follows;

A) SPS-1: Envisaged for controlling impact of overloading at Akola & Aurangabad areas : As agreed between MSETCL & APL as intimated vide letter MSLDC/Tech-SO/1198 dated

01st July 2014.

B) SPS-2: Envisaged for controlling impact of loss of evacuation of lines at APL Tiroda: As agreed at point-1&2 above.

C) SPS-3: Envisaged by NLDC for SR-WR emergency conditions: As per NLDC letter NLDC/SR_synch_SPS dated 11.04.2014.

APL Tiroda have intimated that the SPS has been implemented.

14.3) SPS for reliable evacuation of Sipat generation:

MS WRPC informed that the SPS was discussed in the special meeting held on 03.09.2013 at

TAPS 3 & 4 wherein NTPC representative made a presentation on the SPS.

Further the proposal for SPS at NTPC Sipat was discussed and examined by WRPC & WRLDC

in a meeting held on 18.03.2014 and following was decided:

a) If the Ex-bus generation at Sipat is more than 2200MW (which is 110% of the rated capacity

of both the ICTs) and both 765kV Sipat-Bilaspur lines or 765kV Bilaspur-Seoni lines trips,

NTPC shall back down generation quantum equal to (Ex Bus Generation-2200MWs)

automatically. Appropriate unit selection at NTPC Sipat may be decided by NTPC.

b) Even after backing down the above quantum at “a”, the loading on ICTs is above 100%,

NTPC shall manually back down/trip the generation, so that the loading on both the ICTs is

acceptable.


NTPC have confirmed that the SPS has been put in service.

MS WRPC further stated that an SPS for reliable evacuation of SASAN UMPP was discussed and finalised in the 122nd PCM.

WRPC/TCC noted the implementation of the above SPS.

ITEM NO. 15: HON’BLE CERCS ORDERS ON THE GRID DISTURBANCE OF 30.07.2012 & 31.07.2012.

15.1: Status of compliance of the Protection Audit observations (Petition No. 220/MP/2012).

MS WRPC stated that CERC vide order dated 21.02.2014 in petition No. 220/MP/2012 filed by POWERGRID have observed that “since the protection system is a vital

requirement for the safe and secure operation of the grid, we have decided that in
