distribution venues will facilitated interactions with various groups in field & promote effective deliberations on the related issues. The sub-Committee discussed and agreed to the suggestions as above. The sub-committee requested that the constituent utilities may initiate timely advance action for making necessary arrangements for the meetings accordingly.

8.2 Planned Maintenance Outages of generating units

In pursuance of IEGC clause 5.7.4 “RPC shall submit quarterly, half yearly reports to commission indicating deviation in outages from the plan along with reasons. These reports shall also be put up on the RPC website.” Accordingly details of planned maintenance of thermal generating units available in this office during the Fourth quarter (April 11 to June 11) for the year 2011-12 was enclosed at Annex- 8.2. The deviation report from constituents is yet to be received. SE(O), WRPC requested the utilities to furnish the data within ten days otherwise the existing status shall be intimated to the H’ble commission CERC .

The Sub-Committee noted the above.

8.3 Construction of Garudeshwar weir for reversible operation of RBPH of SSP:

In the 425th OCC meeting, NCA have given a proposal for the construction of weir at Garudeshwar so that reversible operation of RBPH at SSP can be carried out. The proposal is enclosed in Annex 8.3(A). Since the GETCO representatives were not present in last OCCM because of heavy rain, the committee decided to present NCA representation in the forthcoming OCC. The hand out of presentation of NCA was enclosed at Annexure 8.3(B) in minutes of 425th OCCM for reference of constituents.

During the 426th OCC meeting Shri N K Bhandari, Member(Power), NCA explained the usefulness of the above project- namely water can be pumped back and pumped storage utilization of water can be done. The details of the anticipated cost and the project is given in the presentation, enclosed at Annex Annexure 8.3(C).

GETCO representatives expressed that the above power is a clean power and the

project shall facilitate the load dispatchers by providing a facility of pumped storage. Other representatives from MPPTCL, MSETCL and CSPTCL expressed that from technical and operation point of view it is desirable to have a facility which shall provide for pumped storage facility. However the commercial and all other related aspects of the project may require to be looked into by the concerned groups.

8.4 Overloading of 220 kV Kawas-Ichchhapore line:

In the 424th OCC meeting AGM(OS), NTPC (WRHQ), Mumbai intimated vide letter No. QSR/OS/WRPC/F17 dated 04.07.2011 that 220 kV Kawas-Ichchhapore line has been overloading on regular basis since last four-five week leading to tripping of Units & station blackout at Kawas. The tripping details of lines & units is enclosed at Annexure 8.4(A).

Further CE(SLDC), GETCO informed vide letter No: SLDC/CE/MIS/2761 dated 06.07.2011 that the 220 kV Kawas-Ichchhapore line has been overloading on regular basis due to heavy drawl by M/s Essar Power Limited. The detail matter is enclosed at Annexure 8.4 (B).

Since GETCO & ESSAR representative were not present in last meeting hence it was decided that the same was to be discussed in the forthcoming OCC.

426th OCCM MINUTES

During the 426th OCC meeting Shri R K Aash DGM, NTPC Kawas gave a presentation of the problem enclosed at Annexure 8.4(C), which is summarized as below:

1) The loading on 220 kV Kawas-Ichchhapore section is around 300 to 350 MW as the generation at Kawas is in the range from .300- 600 MW. Sometimes power from Haldarwa is circulating to Essar.

2) The fluctuation of high loading may lead to damage to substation equipments on the above feeder requiring immediate replacement. The overloading had however led to tripping of units at Kawas on 16.06.2011 NTPC seriously requested the sub-committee to address the issue suitably.

3) It is therefore suggested to limit the loading on these lines to safe values, if required by opening of lines by GETCO.

4) GETCO were requested to briefly outline the cause that might have led to the present situation of overloading.

Addl CE SLDC, GETCO stated that 220 kV Ichchhapore is further connected to Essar

and from there to Sachin via D/c line. Since Essar power is not maintaining Injection/ Drawl as per Schedule therefore heavy drawl takes place from 220 kV Kawas- Ichchhapore line. He further stated that various messages were issued by GETCO to Essar to maintain grid discipline. He added that at present 220 kV Kawas – Vav line is LILOed at Ichchhapore with LILO of around 1 – 1.2 km length.

Shri Tushar Bhat Sr. VP, M/s Essar stated that the loads in Essar had increased due to

increase in production capacity. Further due to gas non availability the generation availability was not adequately large as a result Essar had to draw power from the grid.

The Sub-committee observed that 220 Kawas- Ichhapure line loading should be

restricted to safe levels so that damage to equipment at Kawas is avoided. GETCO proposed that the portion from 220 kV Kawas- Ichchhapore may be replaced

by high ampacity conductor so that the problem could be resolved. Accordingly he requested that the matter may be taken up in Standing Committee on PSP of WR.

NTPC were of the opinion that increasing the ampacity of the conductors may take care of the problem of transmission line but not of the bay equipments owned by NTPC. Further the high ampacity and corresponding low resistance is likely to lead to an increase in the power flow on 220 kV Ichhapore – Kawas line. Hence they proposed that the existing LILO of 220 kV Kawas-Vav line at Ichhapore may be removed and the line may be made 220 kV Kawas-Vav D/c, as per original scheme. Further they stated that GETCO had commissioned two bays in Kawas NTPC switchyard in 1999 and instead may add a D/c line from 220 kV Kawas – Ichhapore. GETCO representative intimated that because of severe ROW problem this may not be feasible. NTPC further requested GETCO to survey all existing double circuit towers through which LILO has been done and were of the opinion that it may be feasible to construct 220 kV Kawas-Ichhapore D/c line without any major changes in existing transmission line system. This will solve the problem on permanent basis. GETCO representative agreed to look into the same and revert back.

NTPC informed that at present the 220 kV Kawas-Haldarwa 1 & 2 are kept off at times to control the loading on 220 kV Kawas-Ichhapore. NTPC further requested to keep open Kawas-Ichhapore line, keeping it as emergency standby and restoring Kawas-Haldarwa-I & II lines in service for increased system stability.

The sub-committee discussed the matter and suggested that the following three alternatives may be reviewed by GETCO in view of above and reverts back in the next OCCM for further action on the matter.

426th OCCM MINUTES

12

(1) Replacing the 220 kV Kawas- Ichchhapore portion of conductor with high ampacity conductor.

(2) Alternately LILO the second Kawas-Vav line at Ichchhapore keeping the portion from Vav- Ichchhapore LILO point open and charged from Vav end. This would make the configuration as 220 kV Kawas- Ichchhapore D/c and Ichchhapore (LILO) point – Vav D/c open and charged from Vav end. In that case necessary availability to PGCIL for 220 kV Kawas- Vav D/c could be given as line is kept open due to grid constraints.

(3) The existing LILO of 220 kV Kawas-Vav line at Ichhapore may be removed and the line may be made 220 kV Kawas-Vav D/c, as per original scheme. Instead add a D/c line from 220 kV Kawas – Ichhapore. Also restore the 220 kV Kawas-Haldarwa 1 & 2 Ckts.

Further Sub-committee requested M/s Essar that the dispatch instructions of

GETCO may be strictly complied with so that line loading remains within safe limits.

8.5 System Studies for APL:

APL unit 6 of 660 MW had been synchronized but the generation in the Adani TPS complex could be kept at an ex-bus value of up to 1800 MW. SE(O), WRPC informed that a system study forwarded by GM,CEA was carried out jointly by CTU/CEA/GETCO/WRLDC/WRPCon 05.08.2011 at New Delhi and the following was recommended as outcome of the study.

For transfer of power from APL Mundra 6th unit of 660 MW as an interim arrangement till availability of 400 kV APL Mundra – Zerda D/c line following requirement need to be met :- i) Commissioning of 38% FSC on 400 kV APL Mundra-Dehgam D/c ii) Commissioning of 400 kV Limbdi-Vadavi-Zerda D/c line iii) Operationalization of SPS for instantaneous tripping of one 660 MW unit in the

event of outage of one circuit at 400 kV level iv) Existing SPS scheme is to be modified for instantaneous tripping of one 330

MW unit at 220 kV level in the event of outage of one circuit at 220 kV level at APL

v) Operation setting and performance of SPS shall be coordinated with WRLDC, SLDC GETCO and WRPC and should be in operation as per the outcome.

vi) Dispatch above 1800 MW at APL shall be as per the SLDC / WRLDC instructions based on real time operational conditions

Addl CE, GETCO stated that M/s APL may submit the complete details of proposed SPS along with tripping scheme of 330 MW unit at 220 kV level. APL representative informed that they have worked out the SPS in the case of non availability of FSC. Addl CE, GETCO stated the commercial aspects shall however require to be addressed before any additional dispatch instructions (above 1800 MW) can be issued by SLDC GETCO.


8.6 Long outage of line on system over voltage:

CM WRTS-II intimated vide letter no. WRTS-II:VD:O&M:DB:253/933 dated

05.08.2011, that in WRTS-II, the following 400kV lines connected to MPPTCL system are kept out of service on system constraints (system over voltage/over load condition) since more than 2-3 months. These lines are to be charged periodically for some times to check its

EE, SLDC- MPPTCL agreed to look into the matter & allow test charging as early as

possible. Sub committee also suggested charging from 66kV or 132kV line crossing may be

explored so that these open lines are kept charged and prevent any unwanted incidents. The Sub-Committee noted as above.

8.7 RGMO Analysis:

• WRLDC representative informed that they are regularly reporting the performance of RGMO response in the OCC forum. Presently detailed analysis of the 59 units(14,465 MW) out of 73 units(14,756 MW) that have confirmed participation in RGMO. SCADA data is not available for 14 units (291 MW). The following table shows the break up of analysis of 73 units, carried out during July-2011.

• WRLDC stated that they have not yet received information regarding Ghatghar Hydro units (2x125MW) and JSW Jaigad units (3x300MW) and had requested the concerned utilities to confirm the status at the earliest. WRLDC intimated that 13 units (790MW) had applied for exemption to CERC. 96 units (14350 MW) have informed that there are some problems in implementing RGMO. WRLDC intimated that generators were requested to approach CERC in case the problems continue to persist before the problems get cleared and RGMO made operational that generators may intimate nature of problems faced in implementing RGMO. WRLDC intimated that out of 187 (31046 MW) eligible units telemetry was available for 153 units (29210 MW). The other details are enclosed in Annex 8.5. WRLDC were requested to get the telemetry availability expedited.


ITEM NO. 9: DATE AND VENUE OF NEXT OCC MEETING It is proposed to hold 427th meeting of Operation and Coordination Committee of WRPC on 10th September (Saturday) 2011 at OMKARESHWAR hosted by NHDC.
