7 ITEM NO. 3: OTHER RECOMMENDATIONS (OF ZALTE COMMITTEE) A. Defense Mechanism for high frequency After detailed studies by WRLDC following units were identified for automatic tripping at high frequency (51.5 Hz) to help arresting the rise of frequency in case of islanding of WR from rest of NEW grid : 1. KSTPS-7 (500 MW) 2.VSTPS-7 ( 500 MW) 3. CGPL-10 (830 MW) During the TCC meeting held on , Member Secretary I/c WRPC had informed that in the PCM meeting held in 7 th September 2012 in Pune, different utilities are adopting different high frequency trip settings with different time delays and there was not surety of tripping of these units of generators. He had informed that the intention of the Zalte committee was to identify three units, checked by simulation studies, which would definitely trip at 51.5 Hz. During the 21 st WRPC meeting, ED(Commercial), NTPC WR intimated that the matter regarding tripping of NTPC units Korba-7 and VSTPS-7 was discussed by the NTPC Corporate and in the opinion of NTPC high frequency situation does not warrant a tripping of the unit. He informed that the machine will be fully unloaded by governor action and if further discussions are required the same can be discussed in the 29 th November 2012 meeting. In the meeting held on , NTPC expressed concern that in the grid of 40,000 MW, identification of units should be done equitably. Only NTPC units should not be singled out for the said issue. NTPC representative made following points: i. Rise in frequency is not a situation which warrants drastic action to trip units to reduce generation, as it cannot cause a collapse of the power system, unlike the situation of low frequency. High frequency can be easily controlled by controlling the generation. From the system point of view higher than nominal frequency is not considered dangerous/harmful to the system and system equipments. ii. At frequency varying from Hz, all thermal machines in the system (except the older mechanically governed machines), including CCGT units will start unloading as per the droop characteristics. Assuming a governor droop Agenda for 22 nd WRPC meeting to be held at Gandhinagar on

8 of 5%, this would result in reduction of 20% of the generation capacity in service, for a frequency rise of 0.5Hz, above this threshold. This unloading feature can neither be offset beyond 51.5Hz nor can it be prevented, being a safety feature. iii. CCGT units at Jhanor start unloading at 51.2Hz and are wired to trip at 51.7Hz. Kawas CCGT units start unloading at 51.2Hz as per its governor droop. iv. In the event of such a frequency rise it is likely that some generators trip during the re-adjustment of their process, inadvertently. During the said disturbance also such tripping had taken place. If the total generation available after such intended and inadvertent unit outages fall short of the load, the system will be facing a far more disastrous frequency decline situation. In reply, Member Secretary I/c, WRPC intimated that a quick and adequate response in generation shedding is required under such disturbances. The tripping of above units have been arrived by giving due considerations to the above facts and system studies carried out by WRLDC. Also it may be noted that the above trippings have been envisaged after resorting to all the measures required to be undertaken under such circumstances by WRLDC in the real time grid management. Therefore NTPC should not feel that the above units have been singled out. In view of system security, NTPC may agree to the above recommendations of WRPC and implement the tripping of above generators at high frequency of 51.5 Hz. WRP Committee may like to discuss. B. SPS of 400 kv Bina-Gwalior lines: Following Units in WR were to be considered for backing down to the tune of 500 MW in the event of tripping of Agra-Gwalior lines and Bina-Gwalior lines : B. ) Korba, Sipat, Vindhyachal STPS to control power flow towards ER ii) CGPL & SSP* to control power flow in Zerda-Bhinmal-Kankroli lines iii) JP Bina to control power flow in Bina-Mehgaon-Gwalior lines & iv) ISP* to control power flow in Badod-Kota-Modak lines Agenda for 22 nd WRPC meeting to be held at Gandhinagar on

9 *Since SSP and ISP are hydro units and may not be always available, Committee recommended backing down of 500 MW at Korba, Sipat, Vindhyachal, CGPL and JP Bina. During TCC meeting held on GM, NTPC stated that NTPC units are participating in RGMO. He stated that CERC norms require generation backing down from short term, then medium term and long term units. These units are not transacting with any utility in NR. Hence backing down of generation on SPS is not required. Member Secretary I/c WRPC stated that in case of 400 kv Agra-Gwalior tripping, a SPS is under implementation under which NR system trips loads and WR system has to back down generation. Hence this backing down is required and also the total quantum is only 500 MW which is small as compared to grid size. Since this is a protection scheme, the same may be agreed to in the interest of grid security. Chairperson, WRPC stated that this SPS is required when there is an extreme emergency and not normal Scheduling and withdrawal of units. He stated that if NTPC wishes to go through the simulation study they are welcomed to coordinate with WRLDC. But since WRLDC has done the study and identified the units accordingly, for the WR system interest NTPC need to accept the same. WRPC recommended as above However NTPC continued their reservation and requested for further deliberation in a meeting on 29 th November 2012 wherein NTPC representative stated that none of the stations named in the SPS action list have any transaction to NR and hence consumption from these stations is within Western region only. Hence an SPS is being planned for the said lines, the same should not involve the NTPC stations mentioned. The stations with inter-regional transactions on the said line may be considered under the SPS action list. In identification of the generating units to control flow to ER, a cue may be taken from CERC Long Term, Medium Term Open Access Regulations, 2009 which provide curtailment of power scheduled to short term customer first followed by medium term customers and long term customers for the reason of transmission constraint or in the interest of grid security. Therefore to control flow towards ER the generating stations availing interregional links to export power beyond WR should be identified and put under SPS. Agenda for 22 nd WRPC meeting to be held at Gandhinagar on

10 During discussions it was felt that, the above arguments are valid during the steady state conditions. Also the scheduling is done based on the assessment of availability of transmission corridors by considering designed contingencies stipulated in IEGC. However in real time, as seen during the GDs, there is hardly any time for manual intervention for taking corrective actions. The actions suggested above by NTPC may require considerable time. Further the electrical flows follow law of physics and curtailment of schedules may not be a solution for maintaining the system stable under tripping of these lines, since this may lead to rush of power in the other corridors and may lead to unnecessary tripping other elements in WR system. MS, WRPC stated that the above units have been identified based on the sensitivity analysis carried out by WRLDC and these studies showed that the power flow in Bina Gwalior- Agra corridor is more sensitive to the above units. Generation control at these units would control power inrush on other corridors after tripping of the line. The total quantum of backing down from all the above units envisaged in the SPS is only 500MW, as such NTPC shall not insist on excluding their units from SPS. Therefore the SPS for backing down of generating units, in the event of tripping of Agra-Gwalior lines would have to be implemented, for the security of the grid. However NTPC retained their stand and did not agree for participating in back down of generator as envisaged in SPS of Gwalior-Agra/Bina-Gwalior lines. MS WRPC stated that non participation of NTPC would be again put up to WRPC. In view of contingency of Bina Gwalior-Agra tripping apart from action envisaged by NR, a deliberate effort fro WR is also of paramount importance to save WR. Committee may deliberate further and advise NTPC to participate in defense mechanism scheme being major player in the grid. WRP Committee may like to discuss. ITEM NO 4: IMPLEMENTATION OF DEMAND MANAGEMENT(IEGC 5.4), GRID SECURITY EXPERT SYSTEM AND DEMEND ESTIMATION: (A)Demand Disconnection Clause (d) of Grid code provides for formulation and implementation of state-of-the art demand management schemes for automatic demand management Agenda for 22 nd WRPC meeting to be held at Gandhinagar on

11 like rotational load shedding, demand response(which may include lower tariff for interruptible loads) etc. by each SLDC through respective State Electricity Boards/Distribution Licensees before to reduce overdrawal from the grid to maintain the grid at the frequency in IEGC band. In this regard all SLDCs/STUs may provide following requirements. a) The current status of contingency procedures and arrangements required to enable demand disconnection as mandated under Regulation 5.4.2(c)of Grid code b) Automatic demand management schemes mandated under Regulation 5.4.2(d) of the Grid code indicating date of implementation, the maintenance and operational preparedness of the scheme. c) The contingency procedures to restrict the drawal of its control area whenever the system frequency falls to 49.8 Hz(5.4.2a) and the requisite load shedding scheme to avoid overdrawal at low frequency i.e <49.7 or below(5.4.2b). B. Load Curtailment Planning Clause (e) of IEGC stipulates that In order to maintain the frequency within the stipulated band and maintaining the network security, the interruptible loads shall be arranged in four groups of loads, for scheduled power cuts/load shedding, loads for unscheduled load shedding, loads to be shed through under frequency relays/ df/dt relays and loads to be shed under any system protection schemes identified at the RPC level. These loads shall be grouped in such a manner, that there is no overlapping between different Groups of loads. In case of certain contingencies and/or threat to system security, the RLDC may direct any SLDC/SEB/Distribution licensee or bulk consumer connected to the ISTS to decrease drawl of its control area by a certain quantum. Such directions shall immediately acted upon. SLDC shall send compliance report immediately after compliance of these directions to RLDC. Agenda for 22 nd WRPC meeting to be held at Gandhinagar on

12 C. Demand Estimation for Operational Purposes IEGC clause 5.3 Quote (e) demand estimation for operational purposes is to be done on a daily/weekly/monthly basis initially, mechanisms and facilities at SLDCs shall be created at the earliest but not later than to facilitate on-line estimation of demand for daily operational use for each 15 minutes block. (f) The monthly estimated demand by the SLDC shall be provided to RLDC and RPC for better operation planning (h) In order to facilitate estimation of Total Transfer Capability /Available Transfer Capability on three month ahead basis, the SLDC shall furnish estimated demand and availability data to RLDCs Unquote D. Grid Security Expert System (GSES) Subsequent to the Grid Disturbance on 30th & 31st July 2012, in a meeting held between Union Power Minister of India with Chief Ministers / Power Ministers of States of Northern Region on 06th August 2012, a 12 point resolution was drawn to ensure that such type of incidents do not occur in future. Point No.11 pertaining to defense plans stipulated that POSOCO would evolve a contingency load shedding protocol, especially when non frequency related load shedding is required. Based on the template prepared by POSOCO for ten number of scenarios when the power system would be under stress, POWERGRID has planned an automated defense plan for all five regions named as Grid Security Expert System (GSES). POSOCO vide letter No. POSOCO/NLDC date 11 th Sept 12 has submitted a detailed plan on Automated defense plans for the All India electricity grids to CEA, CTU, RPCs and CERC and requested that a discussion on the same may be Agenda for 22 nd WRPC meeting to be held at Gandhinagar on

13 facilitated at the RPC level so that state-wise details are frozen and any other state specific scheme that may be required could also be finalized. However, in a meeting taken by Additional Secretary, Minister of Power on 12th January 2013 in NR, it has been decided that GSES be discussed in the ensuing meetings at RPC level. Further order date issued by CERC on the hearing held on 8 th Jan 13, in petition No.264/MP/2012, had also directed for discussion of the schemes at RPC forum and the recommendations of the RPCs be placed before the Commission for consideration and necessary directions. As per clause 10 of the above order, Quote Accordingly, we direct that the Regional Power Committees of all regions shall discuss the issue of implementation of the Automatic Demand Management Scheme at the SLDC/distribution company level as an agenda item within one month from the date of issue of this order and file their decisions on affidavit within one week thereafter after serving the copies thereof on all the constituents of the respective RPC. Since the Automatic Demand Management Scheme is required to be implemented by SLDCs through their respective State Electricity Board/Distribution Licensees in accordance with Regulation 5.4.2(d) of the Grid Code, we direct that all Distribution Licensees would also participate in the respective RPC meetings and their views should be taken into consideration. We further direct the SLDCs to provide all necessary data and assistance to NLDC and respective RLDCs for effective implementation of the Automatic Demand Management Scheme. Unquote In the recently held 116 th Protection Committee Meeting on 30th & 31st January 2013, WRLDC requested for inclusion of agenda point about Grid Security Expert System (GSES) based on the template prepared by POSOCO for ten number of scenarios when the power system would be under stress. In the meeting, WRLDC gave a presentation about the ten number of scenarios which requires automatic action for safe system operation and about the common logic for operation of the scheme. It was explained by WRLDC that out of the ten scenarios, 9 are for Agenda for 22 nd WRPC meeting to be held at Gandhinagar on

14 Demand/load disconnection schemes and the same can be implemented with the help of SLDCs and DISCOMs for complying Regulation 5.4.2(d) of Grid Code. It was earlier decided in the 443 rd OCCM that preliminary discussion would be held in 116th PCM on 30th and 31st January, 2013 at Nagpur and then in next OCC and outcome would be placed in next WRPC meeting to be held on 25th and 26th February, Report prepared by POSOCO is available on the link pdf. This issue have already been discussed at 24 th TCC & 27 th NRPC meetings held on 29/30 th November 2012 respectively. Discussion in the GSES held in NRPC Meeting and CSPTCL comments on the subject are enclosed at Annexure- 4. The committee may discuss GSES in detail and arrive at common philosophy so that further modalities for implementation could be discussed further. ITEM No. 5: PERFORMANCE OF WR GRID DURING OCTOBER 2012 TO JANUARY SYSTEM PERFORMANCE Frequency: During months of October, November, December 2012 & January 2013, the grid operated in the IEGC frequency range of 49.7 Hz to 50.2 Hz for %, %, % and % of time respectively.

The region faced capacity shortage in the range of 590 MW to 2315 MW (peak deficit of 1.42 to 5.64%) respectively during these months. The details of unrestricted peak demand, demand met and energy requirement and availability are as furnished at Annexure-5.1 (b). 5.2 Voltage Profile Overall voltage profile had been satisfactory during the period under review. However, instances of low and high voltages beyond the IEGC specified operating range were observed at some of the EHV sub-stations in the region. Higher voltages in the range of 421 kv to 442 kv were noted at Indore, Itarsi, Karad, Dhule, Kasor, Bhilai, Jetpur, Bina, Gwalior, Nagda and Khandwa substations. Also the 765 kv Seoni Substation touched to 806 kv on 13 th December, To contain high voltages WRLDC resorted to opening of lightly loaded EHV lines on certain days. Agenda for 22 nd WRPC meeting to be held at Gandhinagar on

17 The detail of voltages at important 400 kv and 765 kv sub-stations for the months October 2012 to January 2013 is placed at Annexure AUFLS Performance. The month-wise details relating to performance of AUFLS scheme in Western Region during the period October 2012 to January 2013 in terms of quantum of load relief obtained and number of occasions the UFR operated is at Annexure-5.3. Frequency didn t touched 48.8 Hz during the period October 2012 to January 2013 and as such there were no UFR operation in WR grid. WRP Committee may like to Note. ITEM No.6: ANTICIPATED POWER SUPPLY POSITION IN WESTERN REGION FOR THE PERIOD FROM MARCH 2013 TO MAY 2013 The anticipated power supply position in the region for the period from March 2013 to May 2013 is at Annexure-6. The period under consideration is summer season. The demand will start increasing. The anticipated regional demand is likely to vary between MW to MW and the capacity shortage will be around 7.00 %. In terms of energy, the unrestricted requirement is expected to range from MUs to MUs with regional energy deficit of the order of 5.0 % to 6.0 %. The anticipated Peak demand shortage of 120 to 270 MW in Gujarat, 60 to 130 MW in Chhattisgarh, 1075 to 1350 MW in Maharashtra, 800 to 900 MW in Madhya Pradesh, 30 to 40 MW in Goa, 15 to 25 MW in DD & 20 MW to 30 MW in DNH is likely to prevail. WRPC Committee may like to note. ITEM No 7: ANNUAL LOAD GENERATION BALANCE FOR THE YEAR A meeting of LGBR group was held on 29 th November, 2012 at WRLDC, Mumbai. The group finalized the tentative outage Program of major thermal units for the Year The same was sent to CEA for finalizing annual generating target for the Year & uploaded at WRPC website. Agenda for 22 nd WRPC meeting to be held at Gandhinagar on

18 A meeting for finalizing the generation target in respect of various generating units including IPPs for the year was organized by CEA on It was requested that IPPs expected to commence delivering of power in WR grid during year may furnish month wise generation for intimation to CEA for further needful. Regarding the Annual LGBR for based on data received so far WRPC, preparation of draft Annual LGBR is under progress. WRPC Committee may like to note. ITEM NO 8: UP-GRADATION OF BINA-GWALIOR-AGRA LINK TO 765 KV OPERATIONS: The OCC Sub-Committee discussed the up-gradation work of 765 kv Bina-Gwalior- Agra link. With the present level of power transfer at 765 kv level to NR, they apprehended a very high voltage situation particularly in Seoni, Bina, Gwalior areas. Already many lines are kept open to curtail high voltage. There seems to be no significant increase in generation levels and therefore charging at 765 kv level will increase the voltages further. Accordingly the sub-committee requested POWERGRID to carry out necessary studies, in line with the present generation and anticipated generation and off-peak scenario in WR and chalk out the reactive power absorption requirements so that up-gradation to 765 kv operation of the above lines may eventually take place. The results of the studies may be discussed in the OCC/ Study forum of WR before operation at 765 kv levels commence. WRPC may like to discuss. ITEM NO 9: DECISIONS ON IMPORTANT ITEMS FROM 35 TH SCM HELD ON 03/01/2013 AT GURGAON: Following are the decisions taken in the above SCM. For details kindly refer to the MOM. A. Commissioning of 400/220 kv 315 MVA ICT at Vapi(PG) and establishment of 400/220 kv Kala s/s in DNH 1) In the 35 th SCM matter pertaining to critical loading of GETCO system and commissioning of 400/220 kv 3 rd ICT at Vapi(PG) was discussed. Agenda for 22 nd WRPC meeting to be held at Gandhinagar on

19 2) Since a substantial quantum of DD and DNH was being catered through GETCO system and resulting in the critical loading of 220/66 kv ICTs at Bhilad and Vapi GETCOI s/s, it was decided that after the commissioning of 3 rd ICT at Vapi(PG), in case critical loading of GETCO system is not relieved, a meeting of the stakeholders would be convened to review the 66 kv interconnections between GETCO system and DD & DNH systems. 3) Due to ROW constraints in DD/DNH system, the earlier agreed arrangement was modified as follows: (i) 220 kv Kala Khadoli D/c (ii) 220 kv Kala New Kharadpada switching s/s D/c (iii) 220 kv New Kharadpada switching s/s Kharadpada D/c B. Reactor at 400 kv Bina s/s It was decided to replace the 63 MVAR Bus Reactor at Bina(PG) by 125 MVAR Bus Reactor and keep 63 MVAR Bus Reactor as regional spare. C.

ITEM NO 11: PROCUREMENT OF SOFTWARE: At present the WRPC Secretariat is issuing accounts for commercial accounting. The existing software s for UI and REA were developed using earlier Visual Studio Platforms procured about 10 years back. The complexity of accounting has increased over the time with Inter-Regional transactions, frequent revisions are necessary. Further new regulations for RTA, RTDA, RRF etc., are coming in place. For RTA and RTDA software is developed from local vendor and has a small AMC component. Other software s have to be shifted to newer platforms of Visual Studio Since the bills of the utilities have huge financial implication, so prompt and error free accounting is the need of the present. The manpower at WRPC is limited and so technological software solution in the form of getting some software s developed / maintained from local vendors is required. Some in-house development is also envisaged. It is necessary to procure Visual Studio 2012 for the same. In view of the above, following proposals are made 1) Renewal of existing AMC for software maintenance for RTA and RTDA 2) Procurement of Visual Studio 12 3) Software help for revision of REA/UI for previous cases The expenses for the above can be met within the existing contingency fund and would be of the order of Rs 3 lakhs. WRPC may like to approve ITEM NO. 12: RENEWABLE REGULATORY FUNDS MECHANISM: The Hon ble CERC s order dated 18 th Feb 2011 has given approval for the detailed procedure for implantation of the mechanism of Renewable Regulatory Fund (RRF).

Mock exercise for forecasting and scheduling start w.e.f The following is the brief on the Commission s order dated 16 th Jan Any person could become the coordinating agency, which may be one of the generators or any other mutually agreed agency. This agency shall be referred as Coordinating Agency for the purpose of scheduling, metering and energy accounting. Agenda for 22 nd WRPC meeting to be held at Gandhinagar on

23 2. Pooling Stations that are commissioned on or after should be considered for the purpose of RRF mechanism. Accordingly the IEGC-2010 would be amended by the Hon ble Commission. 3. Payment should be similar to the conventional generators i.e. Wind and Solar generators should be paid at the contract rate as per the schedule and UI mechanism would ensure, the liability of which would be in accordance with the dispensation for Wind generators in the Grid Code. 4. Reference rate for contract is fixed as Rs.4/kwh fro NEW grid and Rs.5/kwh for SR grid. 5. Mutually agreed mechanism shall be developed by the coordination agency and the Wind generators connected to that pooling station on account of sharing the variations with reference to the schedule. In case of disagreement, the UI charges should be shared based on actual generation on wkly basis. 6. The IEGC_2010 and the approved detailed Procedure for implementation of RRF will be amended/revised in line with the above proposals. WRLDC vide letter dated 4 th Feb 2012 had requested all SLDCs to send the required data to WRLDC on weekly basis for the previous week for preparation of energy accounts by WRPC secretariat. The copy of the letter is enclosed at Annexure-12. The following points need to be discuss: Modalities of weekly sending the required data in the enclosed format SLDCs may intimate the coordinating agency for the purpose of scheduling, metering and energy accounting. Status of availability of ABT meters at Pooling stations WRP Committee may discuss ITEM NO. 13: EVACUATION OF POWER FROM KORBA STPS-III OF NTPC. Back Ground : In the matter of evacuation of power from Korba unit 7 of stage III of NTPC station after declaration of commercial operation (COD) of the unit till commissioning Agenda for 22 nd WRPC meeting to be held at Gandhinagar on

24 of the identified 400 kv Raipur-Korba D/c line, Hon ble CERC vide para no 32 of order dated in petition no 122/2011 has directed as follows: Quote: In view of the foregoing discussion, we have come to the conclusion that the petitioner is bound by the terms and conditions of the BPTA and the Implementation Agreement signed by it with the CTU. However, after allocation of power from Korba-III by Government of India, Ministry of Power to the western region beneficiaries and execution of PPAs by the petitioner, the western region beneficiaries have become long term customers by operation of Regulation 2(1)(m) of the Connectivity Regulations. The long term customers have right to schedule power on long term access from Korba-III on the available spare capacity and such scheduling shall have priority over the medium term open access and short term open access. The ATS for Korba-III was declared under commercial operation with effect from Consequently, scheduling of power from Korba-III for the period from to on the existing transmission capacity shall be deemed to have been made on long-term access. The energy and UI accounts shall be revised and settled accordingly. Un-Quote The WR Power Committee in the 18 th WRPC meeting held on decided that WRLDC would refund whatever charges collected by WRLDC from all the constituents on account of short term scheduling of power from Korba-III and would furnish necessary data to WRPC Secretariat to revise the energy and UI accounts and suggested that accounting details may be finalized based on data to be furnished by WRLDC in line with the above mentioned CERC order dated In order to implement the above order of Hon ble Commission, WRLDC have submitted the 15-minute block-wise data viz DC of unit no 7 of Korba-III, entitlements of beneficiaries of Korba-III, their Long-Term schedules from Korba-III and related data necessary for preparation of revised energy and UI accounts data on Accordingly, the REAs have been revised on During examination of revision of UI based on the data submitted by WRLDC it was observed that the revised schedules submitted by WRLDC remained Agenda for 22 nd WRPC meeting to be held at Gandhinagar on

25 unchanged and there would not be any change in payable/receivables on account of this for the above period. Hence the revision of UI A/c s was not undertaken. In the 61 st CCM, while discussing examination of the revision of UI, beneficiaries expressed that during few occasions they were unable to revise the schedules since the schedules were treated as STOA and any revision of the requisitioned schedules would not have been effective before expiry of a minimum period of two (2) days and not from the fourth time block as in case of LT schedules. Conversion of STOA schedules of beneficiaries to LTA schedules without any change in schedules due to revision of DC (as available in LTA schedules) have deprived the beneficiaries to avail the benefit of revision of schedules due to revision of DC which otherwise would have been available had the schedules been treated as LT schedules. The Commercial Committee suggested forming of a small group comprising of members from constituents, NTPC & WRLDC who would look into such instances and the practicability of implementing post-facto revision of schedules and give its recommendation accordingly. The group met on , and it was decided that NTPC would submit following data for the period to for revision of schedules:- (i) (ii) (iii) (iv) (v) date and time of tripping of Korba-III unit declared date and time of restoration of the unit actual date and time of restoration of the unit DC prior (at the time of tripping) DC after restoration (at the time of restoration of the unit). During the 20 th WRPC meeting held at Indore on , WRLDC and PGCIL representatives informed that a petition has been filed with Hon ble Appellate Tribunal against the above order of Hon ble CERC by PGCIL. MPPMC in the meeting requested to issue the revised UI account in defined time frame preferably before next WRP Committee meeting to be held in September 2012, which was agreed by the WRP Committee. WR Power Committee in 20 th WRPC recommended that since there is no stay on Hon ble CERC order by Hon ble Appellate Tribunal, the CERC directives could be Agenda for 22 nd WRPC meeting to be held at Gandhinagar on

26 acted upon so that the dues are settled as per CERC order, revision of UI A/c s shall be carried out by WRPC on receipt of revised data from WRLDC. As decided by small group comprising of members from constituents, NTPC & WRLDC regarding submission of data by NTPC, NTPC vide dated submitted the data which was circulated to the beneficiaries and WRLDC for validation vide WRPC letter WRPC/Comml-I/3/ABTREA/2012/739 dated and reminder to beneficiaries for forwarding their comments if any by , vide letter WRPC/Comml-I/3/ABTREA/2012/864 dated MPPTCL vide their letter 07-05/RPC-14/1273 dated have intimated that the data submitted by NTPC was verified and is in order. WRPC vide letter WRPC/Comml-I/3/ABTREA/2012/904 dated requested WRLDC for revision of schedules based on the data forwarded, observations of GUVNL and as per the decision taken in the meeting held on 14 th May 2012 at WRPC. WRLDC vide letter WRLDC/MO-II/2012/6806 dated have intimated that the Data forwarded in the above matter only contains tripping details of NTPC Korba Stage-III and with this data, the schedules cannot be revised and 96 block wise DC which is agreeable to all the constituents is required for revision in schedules of NTPC Korba Stage-III. Further POWERGRID did not agree with the aforesaid CERC order dated and has submitted its appeal before Appellate Tribunal against the CERC order. The same has been accepted by Appellate Tribunal and the first hearing already taken place on Further they have intimated that the matter is still sub-judice and the decision of Appellate Tribunal is awaited, the matter will be settled after the decision of Appellate Tribunal. WRPC in view of the decisions of 20 th WR Power Committee, vide letter WRPC/Comml-I/3/ABTREA/2012/1296 dated , requested WRLDC to review their stand expressed in the above letter. WRLDC vide letter No. WRLDC/MO-II/2012 dated have forwarded the revised schedules data as per the decision of 62 nd CCM. REA and UI revisions with respect to Korba-7 has been completed (UIs and REAs for the period March-11 to June-11 have been revised). The revision of REAs and Agenda for 22 nd WRPC meeting to be held at Gandhinagar on

27 UIs on account of inadvertent errors in meter and scheduled data has been taken up and REAs & UIs for the month of Feb-12 & March-12 have been completed. To freeze the REA accounts meeting would be held in the last week of the month. TCC/WRPC may like to note. ITEM No.14: SCHEDULING OF KAWAS AND GANDHAR: In the 63 rd CCM NTPC representative stated that the technical constraints in running the units at lower than technical requirement of machines was discussed and noted in 442 nd and 443 rd OCC meetings. NTPC requested beneficiaries for scheduling of Kawas and Gandhar at least up to technical minimum during night hours for on-bar gas turbines in combined cycle mode taking into account their day s total energy requirement. NTPC also intimated that Kawas and Gandhar stations are getting schedules less than technical minimum during night hours. Further, the less schedules during Night hours results in the unintentional over injection by stations to maintain the technical minimum generation level. Further, NTPC mentioned that, as per the latest Govt. notification, the under-utilized portion of cheap domestic gas may get diverted. In the 63 rd CCM constituents responded that they are not in a position to adhere to technical minimum schedule during night hours in view of strict adherence to merit orders and injections due to must buy provision for purchase from renewable sources (specifically wind energy in case of GUVNL) etc. Beneficiaries also mentioned that although they are conscious of the fact that under-utilization of cheap domestic gas allocated for Kawas and Gandhar may lead to its diversion, they are not in a position to schedule this power in view of reasons noted above. TCC/WRPC may discuss ITEM No.15: DECLARATION OF TRANSMISSION ELEMENTS INTO COMMERCIAL OPERATION BY PGCIL. 15.1: PGCIL vide letter No. WRTS:COMML:NGP/102 dated (copy enclosed at Annex.-15.1) have intimated that a 240MVAR switchable line Agenda for 22 nd WRPC meeting to be held at Gandhinagar on
