In last 54 th & 55 th OCCM, request has been made to MPPGCL for furnishing the same to SLDC within a week, but it has not yet been provided by MPPGCL. It is requested that MPPGCL in coordination with NVDA and WRD to, prepare the ten daily reservoir operation table of all their hydel power stations and submit to SLDC at the earliest for optimum utilisation of available water in the reservoirs during the summer season. Member Secretary informed the Committee that Ten daily Reservoir Operation Table of Tons and Bargi have been provided by MPPGCL. He also requested the representative of MPPGCL to submit the Ten Daily Reservoir Operation Table of remaining HPSs at the earliest. 6.4 Operation of LBB and Bus Bar Protection and delay in restoration at ISP:- Member Secretary OCC informed the committee that at Hrs on , while stopping machine no. 7 of ISP, Local Breaker Backup protection operated of Unit No. 7 resulting in operation of 400 KV Main Bus-II Bus Bar protection. 400 KV ISP-Indore-II and 400 KV STPS-ISP lines, which were on Main Bus-II also tripped. The restoration of 400 KV ISP-Indore-II and 400 KV STPS-ISP lines was done at hrs and hrs respectively. ISP did not intimate the reason for delay in charging of these important 400 KV lines. It is indicate that 400 KV ISP-Indore-II and 400 KV STPS-ISP lines form important corridor for transfer of power from Central to West MP and outage of this critical corridor for such a long period without any justified reason is not desirable for safe, secure and reliable operation of the State Grid. The ISP is requested to avoid unwarranted delay in charging transmission elements in future. NHDC representative from informed the committee that the above tripping occurred as the breaker of Unit #7 was stuck. He also confirmed the committee that in future the instance of delayed reporting will be taken care of. 6.5 Non-compliance of SLDC instructions by Gandhisagar HPS Member Secretary OCC informed the committee that on , Wind Power generation in MP was suddenly increased to 1000 MW from 140 MW during the evening peak hours. SLDC had to accommodate such a huge additional power in the system by maintaining the grid parameter within operational limits. As Minutes of 56th OCCM of MP 9

12 emergency measures hydro generation is to be curtailed immediately which is the only possible solution for keeping the grid security intact till the effect of backing down / surrender of power in thermal generating stations is obtained. Gandhisagar Hydel Power Station was instructed to stop three machines for which code were issued at 20:25 Hrs through GCC. The shift officials of Gandhisagar HPS were reluctant to stop the machines even during emergency conditions despite SLDC request to act immediately. After repeated persuasion machines were not stopped by Operation staff Gandhisagar. Finally the matter was brought in the notice of CE (O&M:Hydel) and after his intervention, the machines were stopped at 21:01 Hrs, 21:05 Hrs & 21:10 Hrs. This act of the shift officials of Gandhisagar is violation of Clause 3.83 of MPEGC, Clause 5.1 (d) of IEGC and Sec. 29 of EA-2003 i.e. non-compliance of SLDC instructions. It is requested that the shift officials of Hydel Power Stations may be instructed to follow the instructions of SLDC promptly in future. Member Secretary OCC requested MPPGCL to issue instructions to Gandhisagar officials to comply with SLDC instruction for safe & secure grid operation Scheduling of DVC and Inter-state IPP Power :- Member Secretary OCC informed the committee that scheduling of DVC and Interstate IPP is being done by the WRLDC. Under day ahead scheduling these entities furnished entitlement of MP to SLDC and these entitlements are forwarded to MPPMCL Control Room for preparing requisitions. The requisition received from MPPMCL again forwarded to DVC / IPPs for obtaining their consent to the power requisitioned by the MPPMCL. On receiving the correspondence from DVC / IPPs the same is again forwarded to MPPMCL. Finally, MPPMCL again gives comments (agreed/ Not Agreed) on the revised quantum of power in 15 minutes time block agreed by the generator. Now SLDC punched the final requisition submitted by MPPMCL in WRLDC web based Scheduling Portal and forwarded to the concern. Similar procedure is also being adopted during the real time scheduling. This procedure of scheduling is not mandated in IEGC / MPEGC / BSC 2015 and also consumes the valuable time of system operators of SLDC which is otherwise required for smooth system operation. Also during real time scheduling such procedural delay is causing on scheduling of power from designated time block. MPPMCL in future submit requisition to SLDC only after obtaining the consent of DVC / Interstate IPPs and SLDC shall not make communication with these entities for obtaining consent on the requisition furnished by the MPPMCL and the same requisition shall be treated as final and punched on the web based scheduling portal of WRLDC. Representative of MPPMCL has agreed to the proposed procedure of SLDC for scheduling of DVC, Jaypee Nigrie and Jhabua Thermal Power Stations. Chairman OCC requested MPPMCL to obtain the consent of IPPs for revision in requisition before furnishing their revised requisition to SLDC. It would ensure revision of schedule from the Minutes of 56th OCCM of MP 10

13 designated time block. Further, he also stated that if any commercial dispute/matter arises regarding scheduling of DVC the sole responsibility will lie on MPPMCL. 6.7 Questionnaire on Hydro Generating Stations :- Member Secretary OCC informed the committee that as per decision taken in 18 th meeting of Forum of Load Despatcher (FOLD) held on 21 st November 2016, working Group on Hydro for studying the various aspects of hydro Stations may be formed. NLDC has furnished a a questionnaire on Hydro generating stations which is to be filled and submitted in respect of each hydro generating station to NLDC, New Delhi within a week time on following Id, SLDC vide letter no /RPC-28A/4187 dtd (alongwith Questionnaire enclosed as Annexure-6.7), requested MPPGCL, ISP, OSP and NHDC to submit the reply directly to NLDC under intimation to this office and WRLDC Representative from MPPGCL and ISP/OSP/NHDC informed the committee that the desired information will be provided soon. 6.8 : MONITORING OF SCHEMES FUNDED FROM PSDF :- Chairman OCC informed the committee that it was decided in the 6th meeting of NPC held on 19th December 2016 at Bengaluru, that all the RPCs in the monthly OCC meetings may follow up with the utilities to expedite the completion of schemes by giving due priority. The implementation of most of the schemes is based on the recommendation of the enquiry committee on grid disturbance of July 2012 headed by Chairperson, CEA. Therefore timely implementation of these schemes would enhance the grid security and reliability. Accordingly the details of grant sanctioned from PSDF for the schemes of MP are enclosed at Annexure- 6.8A. The status of implementation of above schemes (physical as well as financial progress) may please be reviewed and the entities are requested to expedite implementation of the schemes. The utilities were advised to furnish the information in the format enclosed at Annexure 6.8B by first week of every month on regular basis to Member Convener, PSDF project monitoring group (AGM, NLDC, POSOCO) with a copy to NPC, WRPC division and SLDC. The matter was discussed in the meeting and Chairman requested MPPGCL & MPPTCL for informing timely as per mentioned above to all the concerned authority under intimation to SLDC. 6.9 MAPPING OF FEEDERS WIRED UNDER AUFLS TO SLDC SCADA :-. Chairman OCC informed the committee that in the 4th, 5th & 6th NPC meetings, mapping of the Feeders / Lines covered under AUFLS on SCADA systems of SLDC's/RLDC's was discussed. NPC have desired that monitoring of the feeders / loads under the AUFLS shall be done at SLDC's / RLDC's, so as to ascertain that the desired results are ensured during the events, frequency falling below the AUFLS frequency settings. In the 6th NPC meeting it was therefore desired that all the loads/feeders wired under the AUFLS is monitored in Western Region also and the progress be submitted to NPC. A list of feeders/loads implemented under AUFLS in WR was compiled at WRPC in 2014 and same is uploaded in website of WRPC under news section and PCM Minutes section. MPPTCL is requested to initiate the process of mapping these feeders in the SCADA System so that same shall be made available to WRLDC. MPPTCL is requested to update the list of feeders under AUFLS and intimate the feeders which have Minutes of 56th OCCM of MP 11

15 6.12 Extension of RGMO/FGMO signal to SLDC/WRLDC:- Chairman OCC informed the committee that as per IEGC 5.2(f), RGMO/FGMO is mandatory for all thermal units above 200 MW and hydro units above 10 MW. Further considering the high penetration of renewable to grid and also the Government target to achieve 175 GW, it is essential to monitor operation of RGMO/FGMO at SLDC/RLDC for ensuring grid security and compliance of regulation. Subsequently SLDC vide letter no /RPC-27/3739 dated and letter No. SE/LD:E&T/693 dated requested MPPGCL/NHDC for integration of telemetry of RGMO/FGMO in RTU installed at power station and forward the object address configured in RTU so that same may also be configured in SLDC SCADA and RGMO/FGMO status may be displayed in SCADA system. However, no feedback in the matter is received, so far. The matter was discussed in length and the Chairman OCC advised OSP to obtain exemption from implementation of RGMO/FGMO from the Commission as the machines are operation below MDDL. Further he stated that remaining all the generators shall take necessary action at the earliest so that the integration of telemetry of RGMO/FGMO in RTU installed at power station can be done and the same may also be configured in SLDC SCADA and RGMO/FGMO status may be displayed in SCADA system by April Availing of outage of Interstate and 400 KV transmission elements: Member Secretary OCC informed the committee that the standard procedure for availing outages on interstate and 400 KV transmission elements has been devised by WRPC and WRLDC in line with guidelines of CEA and NLDC. This process is approved in OCC meeting of WRPC. This procedure has already been communicated to state grid entities for strict compliance by the SLDC. Matter was discussed in various meetings of MP also. As per standard procedure of WRPC, all the proposed outages of interstate and 400 KV transmission elements of next month should be got approved in the OCC meeting of WRPC in the current month. All the constituents of WR shall inform to the WRLDC for readiness for availing outage of transmission elements on D-3 basis i.e. three days before the date of approved outage. During 491st OCC meeting it was decided that non-occ outages should be discouraged. Only under exceptional cases, the request for transmission outage after issue of OCC minutes must be posted through for concurrence of the WRPC members (OCC group ) at least three days in advance (D-3). WRPC members may respond back in within three hours. After three hours the proposal shall deemed to have been concurred by WRPC for further processing by WRLDC. A detailed procedure for approval of transmission lines /elements outage planning procedure in Western Region is attached at Annexure The above procedure will be implemented w.e.f. 01st March, It has been noticed that the standard procedure for availing outages on interstate and 400 KV transmission elements is not followed by the MPPTCL. WRLDC repeatedly instructed MP SLDC to adhere to the approved procedure of outages and stop requesting for routine nature outages in real time of operation. It is requested that the standard procedure finalized in OCC meetings of MP and WRPC must be followed strictly for availing outages on interstate and 400 KV transmission elements, in future and SLDC shall not forward any outage message to WRLDC during the real time of operation except of emergency nature. Chairman OCC requested all the Stage Grid entities to apply for the shut downs as per guidelines stipulated in the procedure enclosed as Annexure All the planned outages of 400 KV Minutes of 56th OCCM of MP 13

16 lines and Interstate lines should be got approved in OCCM of WR. WRLDC shall not allow any planned outage if it is not approved by OCCM of WR. Only emergency nature shut down will be accepted in real time. The planned outage of the State Grid shall also be submitted to SLDC well in advance so that system reliability could be ensured by the SLDC. He also requested all the concerned entities for wide circulation of procedures among field staff to comply with Integration of New Transmission Elements into the Grid:- Member Secretary OCC informed the committee that the transmission system in Madhya Pradesh is growing at a rapid pace. The process of integration/charging of new transmission elements belonging to each entity requires compliance of certain regulatory requirements and sharing of information/submission of documents to SLDC/RLDC. Therefore mandatory documents and not limited to, to be submitted to SLDC/RLDC prior to issue of charging code for new transmission element are as follows:- 1. Copy of approval by Electrical Inspector. 2. Intimation by Transmission Licensee Regarding anticipated charging of new elements (Annexure 6.14-A) 3. List Of Elements to be charged and Element Rating details. (Annexure B). 4. Undertaking by Transmission Licensee in respect of Telemetry and communication (Annexure C). All the intra-state entities are requested to provide the above data in prescribed formats (enclosed) to SLDC/RLDC prior to charging of new transmission elements. The matter has already been discussed and brought to the notice of all entities during 54 th & 55 th OCCM. However, the desired information is still not being furnished for all the new transmission elements. All the intra-state entities are again requested to furnish the required information for integration of all new transmission elements into the grid, to SLDC/RLDC prior to their charging. SLDC representative informed the committee about the matter for timely compliance of regulatory requirement Certification of Declared Capacity of Hydro Generators by SLDC :- Member Secretary OCC informed the committee that CERC vide order dtd in petition No. 40/MP/2016 filed by NHDC, has issued following directions :- Quote Regulation 31 (3) of 2014 Tariff Regulations requires that the declared capacity for any day of the month should correspond to the capacity which a generating station can deliver for at least three hours as certified by the nodal load despatch centre after the day is over. Since the petitioner has declared the capacity based on machine and water availability, MPSLDC cannot restrict the PAFM on the ground that machines were not operated as per the directions of the local authorities. The calculation of PAFM by RLDC/SLDC has to be based on capacity declared by the generator considering machine and water availability finalized by SSRRC. Accordingly, the PAFM of ISPS for the period from to and for all the instances till date shall be recalculated by MPSLDC based on capacity declared by the generator in place of restrictions imposed by local authorities. MPSLDC is further directed to revise the SEA(s) of ISPS and OPS in the light of the above direction Unquote Minutes of 56th OCCM of MP 14

17 Accordingly, NHDC has submitted the revised PAFM for the year to and MPPGCL has submitted the revised PAFM wef to for certification by SLDC. The verification of PAFM submitted by NHDC and MPPGCL is under progress and shall be completed by the end of March The matter was discussed in the meeting. ITEM NO. 7: BLACK-START MOCK DRILL OF HYDEL POWER STATIONS : Black Start mock drill of Hydel stations of MPPGCL :- Member Secretary OCC informed the committee that the last black start mock drill of Gandhisagar Bargi, Pench, Indira Sagar Power Station (ISP), Omkareshwar Power Station (OSP), Tons HPS and Birsinghpur HPS were successfully completed during the year As per IEGC Black Start Mock Drill shall be conducted in every 6 months duration. MPPGCL and NHDC are requested to submit the plan for carrying out black start mock drill of Gandhisagar Bargi, Pench, Indira Sagar Power Station (ISP), Omkareshwar Power Station (OSP), Tons HPS and Birsinghpur HPS for the year Suitable dates may be communicated to SLDC well in advance for making necessary arrangements. Chairman OCC stated that 19 No. of Mock Drills has been conducted in MP at various HPS. The Mock Drill at Rajghat & Madhikheda shall be conducted by June MPPGCL agreed for conducting Black Start at Madhikheda in the month of April Representatives of MPPGCL and NHDC requested SLDC to give suitable dates for Mock Drill Exercise of their Hydel Power Stations. Member Secretary, OCC stated that Black Start Mock Drill of all the Hydel Power Stations except Rajghat could be conducted in the month of May & June, ITEM NO 8: ALLOCATION OF THE POWER TO DISCOM, EAST DISCOM REGARDING: Member Secretary OCC informed the committee that SLDC is allocating the power to DISCOMs of MP as per GoMP Notification dtd effective from and MPPMCL is allocating the unallocated power to DISCOMs on day ahead and real time basis as per the forecasted demand furnished by the DCCs. However, the Energy Deptt. Govt. of MP vide notification No.2211/F-3-13/2016/XIII dtd. 21st March, 2016 has allocated all existing and future generating capacity to MPPMCL for maintaining uniform tariff across the State w.e.f. April Due to more allocation of power to East Discom and less to West Discom the East Discom remains in under drawal and West Discom in over drawal. These leads to gap between average cost of supply (ACS), resulting increase in average revenue realization (ARR) per unit in East Discom. It is requested to provide a solution so as to minimize the under drawal of East Discom and over drawal of West Discom. The date wise under drawal/over drawal of Discoms for the month of Feb.2017 Annexure-8. (upto ) is enclosed as East Discom representative informed that allocation to them is not proper by MPPMCL and the matter was discussed with the committee. Minutes of 56th OCCM of MP 15

18 Chairman OCC requested MPPMCL & Discoms to mutually disuss the matter and resolve the issue with common consensus. ITEM NO 9:Non-reporting of tripping incidence occurred on at 220 KV S/S Sabalgarh:- Member Secretary OCC informed the committee that At around hrs on dtd , 220Kv Shivpuri-Sabalgarh feeder-ii tripped with following indication: Shivpuri - ACN, zone-iii, FT-1, trip ABC Sabalgarh - No indication It is gathered that 160MVA, 220/132Kv transformer No.I&II at 220KV S/S Sabalgarh also tripped at the same time with O/C R phase, E/F indication resulting total failure of 132Kv supply at Sabalgarh, Shivpurkalan and Baroda substations. It has come to notice that officials on duty at Sabalgarh S/s had not intimated about above incidence by hrs to upper substation (220Kv S/S Shivpuri). Thus, the officials on duty at 220KV Shivpuri S/s, Sub-LDC Bhopal and SLDC Jabalpur were in dark about these tripping incidence, resulting delay in normalization of system. It is also gathered that above tripping occurred during shifting of load of 132 KV Shivpurkalan ckt-i to Auxiliary bus at Sabalgarh S/s.Non-reporting of tripping of transmission elements after incidence occurred, is not in the interest of safe,secure and reliable operation of integrated grid. Chairman OCC stated that the above incident is not an isolated incident in Gwalior region as in past many incidences have been observed about non-reporting and charging of elements without obtaining code from SLDC. He also requested MPPTCL to issue suitable instructions to field offices to adhere the grid code for maintaining safe & secure grid operation and avoid the repeatance of such incidences. ITEM NO. 10: AVAILABILITY BASED TARIFF (ABT) RELATED ISSUES: 10.1 Status of AMR system installed at SLDC: SLDC representative informed the Committee about the status of AMR data received through AMR system in the month of Jan He informed that the complete data of 555 meters was received through AMR system and data of 68 Nos meters (Monthly-51 & Partial 17) was not received through AMR system.
