RGGVY VILLAGES ON MONTHLY BASIS

CE(GM), CEA vide letter No. 1/A1/MRP/GM-14/ dated 31.01.2014 intimated the

decision by MoP to monitor the supply of power for minimum 6 – 8 hours to the

villages electrified under RGGVY Scheme or any other rural electrification scheme.

Members were requested to furnish the data in enclosed format to CEA/WRPC

Secretariat at the following email addresses:

[email protected] [email protected] [email protected] Member Secretary, WRPC stated that the above data may please be sent preferably

by 3rd working day of each month in respect of previous month as it needs to be

communicated by this office to CEA.

It has been observed that data upto March 2014 except Maharashtra has been received. SE(O), WRPC intimated that nomination of coordinating officers were received from all but the data was awaited for April-2014 and requested all to send the data urgently in the prescribed formats already furnished by WRPC. The Sub Committee agreed to comply. 8.4 SHIFTING OF FEEDERS FROM GETCO TO DD & DNH

8.4.1 During last meeting, DNH representative informed that regarding power evacuation from 400 KV Kala PGCIL S/s to DNH, due to High Court STAY for one

10

459th OCCM MINUTES

location work was held up. Balance 220 KV line work will be completed by April 2014

end and request was made to GETCO to consider the above situation before

disconnecting power to DNH. The copy of the order passed by District Magistrate of Dadra and Nagar Haveli was sent to GETCO/WRPC/WRLDC/others by DNH. DNH representative intimated that petition was heard by Hon’ble JERC on 9.05.2014 and Hon’ble JERC have directed the parties to file written submissions within 4 days. PGCIL representative intimated that they would complete the line within 15 days of lifting of stay in this case. 8.4.2 Executive Engineer, DD vide letter dated 6.05.2014 (copy enclosed at Annexure-8.4) have intimated that the decision of OCC for shifting of load from 66 kV Vapi-Dabhel feeder (May-2014) after commissioning of 400 kV Magarwada (GIS) s/s. However, PGCIL vide letter dated 16.4.2014 addressed to Secretary, UT of DD and DNH have intimated that the work is delayed due to local protests and PGCIL is making all efforts to complete the Magarwada s/s by June 2014. EE, DD during the meeting intimated that the delay in commissioning of various feeders is mostly due to external factors and agencies and therefore requested SLDC, GETCO to revisit their decision to open relevant feeders. He further intimated they are completely ready with all the lines if permission is given to them to connect with ISTS network at Vapi. CE, SLDC, GETCO while agreeing to statement by EE, DD stated that they had earlier offered to repair one of the Magarwada transformer but there was not reply from DD side. Also, at Vapi there is no margins available to connect any additional load and hence currently commissioning of new S/s, transformer, feeders is must needed. PGCIL representative intimated that Vapi-Dabhel feeder would be completed by July-2014. Member Secretary, WRPC after hearing the view of all directed EE, DD to arrange for a meeting amongst DD/DNH/GETCO/SLDC Gujarat/PGCIL WR-II/WRPC/WRLDC involving Secretary (Power) from Gujarat and DD/DNH. DD representative agreed to convene a meeting shortly after finalizing with Secretary(P), DNH. 8.5 Rescheduling of SIPAT unit No. 5 for boiler license renewal: SLDC, GETCO have intimated that AGM (OS), NTPC, WR-II, vide his letter No. WR-II/OS/2014 dated 22.04.14, had requested for rescheduling of outage of Sipat unit No. 5 (500 MW of which share of GUVNL is 137 MW) for boiler license renewal from 27.04.14 to 01.05.14 instead of earlier approved period from 27.10.14 to 31.10.14 citing the reason of acute coal shortage and subsequent review of their present plant condition. Accordingly, WRPC has concurred the above outage subject to real time condition.

11

459th OCCM MINUTES

GETCO further intimated that granting approval for such unplanned large sized unit outage especially when the system is catering its peak summer demand is not at all desirable and also, NTPC should have made all out efforts to resolve the issue of acute coal shortage and ensure full availability of coal for running their units to their full capacity at such times. GETCO requested that WRPC shall take cognizance of the constituent States in writing prior to granting such outage which is likely to create scarcity of power in the State. NTPC representative intimated that overhauling of the aforesaid unit have already been carried out as coal stock was low during that period hence the generation would not had been available to Beneficiaries even if the outage had not been taken. Member Secretary, WRPC stated that due consideration for shortage of coal during said period and utilizing opportunity outage is good for the grid as a whole but requested all the Constituents to submit the outage proposal to OCC and carry out the same only if approved in OCC. 8.6 Not availing the approved outage of 400 KV APL-Sami line No. 2 by M/s. APL SLDC, GETCO have intimated that M/s. APL had requested on 26.04.14 for availing outage of 400 KV APL-Sami line No. 2 for attending hot spot at Loc. No. 79 top phase and 159 bottom phase on 27.04.14 and they were permitted to avail the same. Accordingly, code was issued by WRLDC for taking out the FSC of the said line. After the FSC was taken out, SLDC-Gujarat requested M/s. APL to reduce their generation in view of possible overloading of 220 KV D/C Hadala-Nyara line (which was already carrying around 220 MW on each line) as line loading of 400 KV APL-Hadala would increase due to outage of 400 KV APL-Sami line No. 2. Despite repeated instructions, M/s. APL didn’t follow our advice and the FSC was taken back in service after about 40 minutes without availing the approved outage of 400 KV APL-Sami line No. 2. Such indolent attitude of M/s. APL shows that they were neither interested in availing the approved outage nor serious about the instructions given to them by the system operator. Whenever any agency wishes to avail outage of any transmission element, they should strictly adhere to the instructions of the load despatcher who is entrusted the job of maintaining the system security, safety and reliability. The instructions of the system operator should be scrupulously followed. APL representative clarified their stand as follows:

1) APL has always followed SLDC/RLDC/NLDC instructions in letter and spirit.

2) In the referred incidence also, switching operations of FSC were carried out only after receipt of valid code. As the code for tripping the line was not received, the said line was not opened. So in this case also we followed all the instructions of SLDC.

12

459th OCCM MINUTES

3) We would have availed the shut down on 27-04-14, had the code been issued for the same.

4) The transmission and Generation are two separate entities of APL

5) DC revision can be advised by generator himself only in case of tripping, synchronization of a unit or due to change in capacity due auxiliary problems

6) SLDC/RLDC are empowered vide grid code to reduce the generation for any constraints by revising schedules on their own. Sequence to be followed for curtailment is also well established i.e. short term first then medium term and lastly long term

7) APL request SLDC to continue practice of advising APL generator the revised schedules in advance so as to take action as desired and without any ambiguity”

The Sub-Committee noted as above. 8.7 Frequent tripping of 400 KV CGPL-Jetpur lines SLDC, GETCO have intimated that on 27.04.14, the 400 KV CGPL-Jetpur line No. 1 tripped on Jetpur: Z-I, R-E, 60.17 Kms. Mundra: Z-I, R-E, 271.1 Kms. at 06:08 Hrs and was restored at 06:25 Hrs and later Auto Reclosure of the said line operated repeatedly thrice during 06:44 Hrs to 06:50 Hrs. Subsequently, 400 KV CGPL-Jetpur line No. 2 also tripped on Jetpur: Z-I, B-E, 53.14 Kms. Mundra: Z-II, B-E, 279 Kms at 06:50 Hrs and was restored at 07:44 Hrs. Also, 400 KV CGPL-Jetpur line No. 2 tripped on 28.04.14 too on Mundra: R-E, Z-1, 162.2 Kms Jetpur: R-E, Z-1, 164.3 Kms at 17:15 Hrs and was restored at 17:37 Hrs. Fortunately, during the above trippings, the CGPL unit No. 10 was under AOH and the total generation from CGPL-Mundra complex was reasonably less and hence, there was no system disturbance. Had the same kind of incident happened when all the five units of CGPL-Mundra complex were running with full generation of around 3750 MW, it would have certainly caused a severe grid disturbance. It’s been quite a long time since the evacuation lines of CGPL-Mundra complex have been commissioned and the system cannot afford to have such frequent trippings of important power evacuation lines. It is highly essential that M/s. PGCIL shall do the needful in order to avoid the recurrence of such incidents at least in future so that the system is not jeopardized. CE, SLDC, GETCO requested PGCIL to carry out outage on low load day(Sundays) and staggered holiday(Wednesdays) to the extent possible. PGCIL representative intimated that lines are frequently tripping due to insulator scaling and replacement work is going on. Replying to request by GETCO, PGCIL representative intimated that they have real trouble with the manpower movement and cannot perform the insulator replacement activity in a day.

13

459th OCCM MINUTES

Member Secretary, WRPC requested GETCO to let PGCIL complete the replacement of insulators work in the remaining stretch as it is going to benefit to GETCO and WR grid as whole in long run.

GETCO agreed to do the needful. 8.8 Strengthening evacuation facility of UMPP Mundra SLDC, GETCO have intimated that a meeting was convened by the Chief Engineer (SP&PA), CEA on 06.05.2014 at CEA, New Delhi to examine the feasibility of utilizing the upcoming 400 KV D/C Essar Salaya (Stage-II) - Bhachau (Bhimasar) Triple Snowbird transmission line. CE, SLDC, GETCO intimated during the meeting that Salaya TPP is not going to be commissioned for at least three years from now and hence the transmission network created needs to be utilized for enhancing reliability of power system. It was preliminarily concluded to terminate this line at Essar Vadinar Stage-I project. Simultaneously, PGCIL is also doing additional 400 KV D/C CGPL Mundra - Bhachau transmission lines and hence, it was proposed to utilize this 400 KV D/C Essar Vadinar - Bhachau CTU line as additional evacuation facility of Mundra UMPP as all of us are aware that there is acute need of enhancing the evacuation facility of Mundra UMPP. OCC appreciated the proposal submitted by GETCO. Member Secretary, WRPC requested to approach SP&PA division of CEA with the proposal and request them to hold special meeting of Standing Committee urgently so take the decision. The decision can then be vetted by WRPC in forthcoming meeting during June 2014.

The Sub-Committee noted as above. ITEM No. 9 : ITEMS FROM WRLDC: WRLDC enumerated the problems that could be encountered during monsoon and requested constituents to follow following suggestions to mitigate the situation. 9.1 Preparedness for the ensuing monsoon season:

The following situations are anticipated based on previous experience during the monsoon.

• Reduction in agricultural load • Sudden reduction of load due to tripping of 11kV/lower kV lines due to stormy

and inclement weather conditions leading to high frequency. Less requisition at all ISGS units during all the day except for 2-3 hours during peak where the requisitions are maximum.

• Sudden rise in demand during dry spells leading to low frequency during peak hours.

• High voltages and network depletion due to manual opening of EHV lines on high voltage or due to tripping of trunk lines on tower collapse

• Violation of flow gates limits and TTC/ATC limits of inter-regional corridors

Suggestion to tackle the above expected scenarios:

14

459th OCCM MINUTES

• Ensuring that all L/Rs and B/Rs are healthy and kept in service. • MVAR absorption by generating units to the machine’s reactive capability limit • Coordination of taps of GTs, UATs and STs at power stations • Review of ICT taps at load centers • Review Voltage grading and time grading adopted in O/V relays. • Shunt capacitor bank switching at distribution level • Availing Reserve Shutdown and controlling of under drawal / over injection. • Weather forecast to be duly considered during operation planning.

Member Secretary, WRPC emphasized the suggestions of WRLDC and requested constituents to be more vigilant during coming months.

9.2 Controlling high voltage scenario in Monsoon

In this regard communication were sent from WRLDC on 22nd Oct 2013 as well on 02nd May 2014. POWERGRID also has been raising the issue vide its letter dated 31st Oct 2013 and 23rd April 2014. It is a matter of concern that even after one year, the scheme approved by WRPC is yet to be commissioned by UT-DNH. The MVA loading of one of the three ICTs at Vapi in April 2014 is illustrated below:

CE, SLDC, GETCO intimated that a demo of similar scheme was shown to DD/ DNH representatives. Member Secretary, WRPC once again stressed the importance of early implementation of SPS at Vapi for grid security. DD/DNH representatives agreed to complete the SPS within a month. 9.7 SPS at Sipat

WRLDC vide letter No. WRLDC/MO-I/1719/2013 dt 21.6.13 requested to take up this matter with the concerned for early implementation of the SPS.

NTPC representative intimated that corporate approval for the above SPS scheme has been obtained and accordingly ICT shutdown have been proposed and approved on 20-21.05.2014 and hence the SPS will be ready and operational by this month end. 9.8 Modification of SPS at CGPL Mundra for tripping of evacuation feeders.

A blackout occurred at CGPL Mundra on 12.03.2014. During discussion in the meeting at Mumbai on 19.03.2014 it was agreed to review the existing SPS at CGPL Mundra for tripping of one or more evacuation lines. WRPC vide its letter dated 25th March 2014 sent a revised SPS proposal with two alternate options (Option-A and

20

459th OCCM MINUTES

Option-B) was to CGPL for their comments. CGPL vide its letter dated 29th March 2014 proposed a third option (Option-C). Thereafter SLDC GETCO vide its letter suggested to include tripping of 400 kV Bachau-Vadavi (Ranchodpura) in the SPS logic. WRLDC vide its letter dated 11th April 2014 suggested that the envisaged SPS for N-2 contingencies that were already agreed by CTU, SLDC GETCO and CGPL, were inadvertently missed in the revised scheme. The matter was therefore discussed again in 458th OCCM. After due deliberations in the 458th OCC, the following revised scheme was agreed.

CGPL representatives intimated that since the disturbance two-three meetings on

SPS requirement have been taken place and every time change in the SPS scheme is

proposed.

Member Secretary, WRPC stated that PCM meeting is scheduled on 15.05.2014 and

final SPS scheme to be implemented will be deliberated and finalized during the PCM.

9.9 SPS at 4x300 MW Balco IPP The SPS at 2010 MW Balco (4x67.5MW + 4x135 MW + 4x300 MW) was to be commissioned by Nov 2013 before commissioning of first unit of 4x300 MW Balco IPP. For the new SPS scheme envisaged for the Balco CTU connection, namely the Grid Islanding and Load Management Scheme (GILMS), Balco had reported to have placed an order with M/s SEL. As discussed earlier, the scheme suggested by WRLDC may be implemented before commissioning of first unit of 300 MW. It was intimated during the 456th OCCM by the Balco representatives that the SPS shall be commissioned by March 2014.

M/s Balco representative intimated that the SPS have been implemented on 30.04.2014.
