NORTHERN REGIONAL POWER COMMITTEE

MINUTES

OF 38th MEETING OF TECHNICAL COORDINATION SUB-COMMITTEE

& 41stMEETING OF NORTHERN REGIONAL POWER COMMITTEE

The 38th meeting of Technical Coordination Sub-Committee (TCC) and 41st meeting

of Northern Regional Power Committee (NRPC) were held on 27th

and28thFebruary,2018, respectively at Surajkund, Faridabad, Haryana.The list of

participants ofthe TCC and NRPC meetings is enclosed at Annexure- I & II,

respectively.

P R O C E E D I N G S O F 3 8t h M E E T I N G O F T C C

1. Sh. Dalip Singh, Director ( Proj.), HVPNLwelcomed the Members of the TCC and

other delegates in the picturesque and historic place of Surajkund. He briefly

mentioned the historic importance of the Surajkund which dates back to 10th Century

AD. He expressed satisfaction that in the winter season the grid was stable and there

was no major incident. He lauded the efforts of all the concerned utilities of Northern

Region and NRPC in this regard. He also mentioned that the trippings due to fog were

less as a result of insulator cleaning and replacement done by utilities. While

mentioning the high voltage problem in Northern Region Grid, due to which a large

number of lines were opened frequently during winter season, he urged that serious

steps need to be taken in this regard. He emphasized that the Coal shortage issue in

generating stations of Haryana as well as that of other utilities in Northern Region is a

cause of concern and urged that this issue must be resolved before peak summer

season. He stated that the previous decisions in TCC and NRPC had been very useful

in resolving several issues and expressed hope that the deliberations in this TCC

would also be helpful in resolving issues amicably.

2. Sh. Asgar Ali Majaz, Chairman, TCC and Development Commissioner, Power, PDD,

J&K welcomed the members and other participants of the 38th TCC meeting. He

thankedHaryana Power Utilities for hosting the meeting and making a comfortable

stay arrangement for delegates.

3. He expressed satisfaction that winter load period in Northern Region had passed

without any significant event affecting grid security. He mentioned that in Northern

Region, during the current year, more than 58 GW demand was successfully met and

load not served was 1.7% and 3.8%, in energy and peak terms,respectively, which

was mainly due to system constraint and commercial reasons. He added that the

availability of power is generally not an issue, as we are meeting 58 GW demand

from 92 GW capacity in Northern Region. In Northern Region except J&K other

States are generally comfortable in power supply. He informed that the State of J&K

is not able to meet its demand mainly due to constraints in distribution and

transmission system, especially in valley area. Commissioning of 220 kV network at

Wagoora and Kishanpur would help in meeting demand in Valley area. At the

distribution level the network strengthening as well as focus on complete metering of

load is required to correctly asses the demand and to bridge gap between demand and

supply. He urged that not only J&K but all the States need to reduce the Aggregate

Technical and Commercial ( AT&C) Losses, which is about 25% at all India level. 4. Chairman, TCC mentioned that some utilities had been overdrawing from grid during

last few months resulting in frequency reduction and endangering the grid security.

During current financial year the frequency remained about 25 % of the time beyond

the permissible limit. This was in spite of frequent ancillary services support. We

should understand that non-scheduling of power from generating stations and

allowing this power to be booked under ancillary services results in extra burden on

Distribution Companies. He requested all the SLDCs and Distribution Companies to

improve load & generation forecasting and schedule power judiciously to optimize

overall costof power as well as to ensure safe & reliable operation of power system. 5. Highlighting the issue of non-reliable communication and telemetry system he

mentioned that efforts are being made, but, the intended results are yet to be achieved,

as at present the data, in NRLDC, from about 30% of Generating/Grid stations in

Northern Region is either not received or not reliable. He stated that theSCADA&

telemetry is Eye & Ear of the power system. The crucial decisions of real time Grid


5

operation are taken on the basis of information from this system only. Non-

availability of complete and correct information may result in wrong decision

resulting in compromise in grid safety as well as in financial repercussions. He urged

all the utilities to make more concerted efforts to ensure the reliable telemetry,

keeping in view its operational as well as commercial importance.

6. While mentioning the project for creating a system for protection data base and

analytical tools, which will help in maintaining a healthy protection system, he

requested all entities to complete internal audit of protection system before start of

peak summer season to ensure availability & healthiness of required protection

system. He also requested the utilities to complete all the activities for summer

preparedness.

7. Expressing his gratitude, Chairman, TCC once again thanked all the participants for

sparing time to discuss the important issues. He expressed his hope that the

discussions would be fruitful, which would go long way in facilitating safe, reliable

and economic operation of NR power system.

8. Sh. M.A.K.P.Singh,Member Secretary, NRPC welcomed the Members of Technical

Coordination Sub-Committee and other delegates ofthe 38th TCC meeting and

expressed sincere thanks to Power Utilities of Haryana for excellent arrangements

and hospitality. He briefly described important issues including Capacitor study,

protection database, summer preparedness etc. to be discussed in TCC meeting. He

also emphasised the importance of RGMO in facilitating reduction of extra financial

burden on utilities in form of charges for ancillary and AGC. Referring to presentation

by Gujarat SLDC, on best utility practices, in recent FOLD meeting he urged all the

SLDCs to follow the best practices for safe , reliable and economic operation of the

grid.

P R O C E E D I N G S O F 41st M E E T I N G O F NRPC

1. Sh. Dalip Singh, Director (Proj.), HVPNLwelcomedSh. P.K.Das, Additional Chief

Secretary, Power, Haryana; Chairperson, NRPC and other Members of the

NRPC.He mentioned that Sh. Das was the first Secretary of the Haryana State


7

Electricity Regulatory Commission ( HERC), which was only second SERC to be

established in the country after Odissa SERC.

2. Sh. P.K.Das, Additional Chief Secretary, Power, Haryana welcomed all the

dignitaries and other participants of NRPC meeting in the State of Haryana at the

picturesque location of Surajkund. While appreciating the efforts of all the utilities in

making the power supply position in Northern Region relatively better, he cautioned

the utilities not to be complacent. He opined that though the power supply scenario

seems to be comfortable, there are still some areas in some States which do not have

reliable and quality power availability. He suggested the utilities to make effort to

supply power as per actual unrestricted demand as in present condition utilities are

supplying power where they want to andnot exactly as per demand.

3. Sh. Das had also expressed concern about the Coal shortage issue becoming

perennial from seasonal. He suggested taking measures to ensure adequate supply of

Coal by taking up the issue with Ministry of Power as well as Ministry of Coal.

Citing example of huge financial losses incurred by State utilities of Haryana in last

ten years, he called for action by utilities for reducing Aggregate Transmission and

Commercial ( AT&C) losses by taking up the power supply activities as business. He

mentioned that the inter-state infrastructure and regulatory environment is well

developed for facilitating a vibrant power market in the country. He advised all the

power utilities to be financially self reliant by adopting business practices, which is

very essential for sustainable power sector in the country. While mentioning the

UDAYA scheme he cautioned the power sector players that one time bail out

scheme should not give a reason to be euphoric, instead, the utilities should find out

ways and means to become financially self sustainable.

4. Sh. Das has also mentioned the challenge of integration of large renewable power

especially Solar power. He stated that due to inherent characteristic of generation

variability from these renewable resources, balancing of the power availability with

conventional resources and modification of load pattern to follow the generation is

need of hour.

5. He appreciated the role of deliberations and decisions in NRPC in resolving the

issues and facilitating the safe, reliable and economic operation of the Northern

Region Grid and expressed his belief that NRPC deliberations would go a long way

in guiding the resolving all the issues.

6. Chairperson, NRPC, and Commissioner & Secretary, PDD, Govt. of Jammu &

Kashmir, Shri Hirdesh Kumar, IAS, welcomed the members of the Northern

Regional Power Committee and other delegates of the 41stmeeting of NRPC. He

expressed his gratitude especially towards Sh. P.K.Das, Additional Chief Secretary,

Power, Haryana for accepting his request and his enlightening words.

7. While applauding TCC efforts in deliberating and resolving several issues, he urged

all the members to implement the decisions in letter & spirit, in a time bound

manner.

8. Chairperson, NRPC appreciated the contribution of all stakeholders in facilitating the

Northern Power system in meeting the highest ever demand successfully. He

mentioned that load not served in the region was significant only in few States. It

was highest in J&K, which is mainly due to distribution & transmission system

constraints. He apprised the house that huge funds had been made available to J&K,

under Pradhanmantri special package, in last two years and most of the works for

improving transmission & distribution system had already been awarded. He added

that several schemes were under progress and with the help of Central agencies like

POWERGRID, REC etc. the works would be completed

successfullyandtheT&Dconstraints would be mitigated very soon.

9. Chairperson, NRPC advised all the concerned utilities to take necessary action for

summer preparedness to ensure smooth functioning of the grid with reliability

&optimum economy. He requested all the generating stations to prepare themselves

for maximising generation during peak summer season by ensuring Coal availability

in thermal generating stations and minimizing outages of Hydro generators due to

silt.

10. He stated that Renewable Energy generation capacity of about 62 GW has surpassed

hydro generation capacity ofabout 45 GW in the country. He cautioned about new

challenges in managing the grid, with more penetration of renewable energy. He

added that all the power sector players should be prepared to adopt new ways and

means like Automatic Generation Control ( AGC), flexing of Coal based generation,

optimization of hydro and gas based generation for meeting peak loads, demand


9

response, storage facilities, latest forecasting techniques etc. to manage the

variability of renewable power. He suggested that the commercial and technical

aspects should be seen in larger perspective for enabling sustainable growth of power

sector. He added that the commercial interest of the individual utility must be seen

but at the same time it should be kept in mind that the smooth operation of the grid is

collective responsibility of all the utilities. He opined that optimization of cost of

power along with ensuring 24X7 power supply to all category of consumers is a

challenge for State utilities.

11. While appreciating the efforts of load dispatchers for running a very large and

complex power system, he emphasized the need for availability of proper,

communication and telemetry facilities in todays power system. He expressed

concern about deficiency in these facilitiesandrequested all the utilities to work on

this issue on war footing.

12. Chairperson, NRPC informed about the major changes in scheduling, metering and

accounting, in form of 5 minute time block instead of present 15 minute time block.

He stated that this would be a new challenge for all the utilities. He added that the

generating utilities must gear up for reliable generation forecasting and the load

serving utilities must take step to improve the load forecasting by using latest

technologies to enable fast decision making, by investing in latest technology for

keeping pace with changing scenario.

13. The availability of adequate and trained man power in power sector organisationswas

indicated as a major challenge by Chairperson, NRPC. He mentioned that there had

been efforts for training and certification in specific areas of power sector, but almost

all the utilities are facing manpower crunch. He advised all the utilities to take

immediate steps to hire adequate manpower and train them to make the manpower

able to deal with ever increasing technical as well as financial and commercial

complexities in power sector. In this regard, while applauding the efforts of

NRPCsectt. fortaking steps in skill development by organising several training

courses, he advised toorganize more of such training courses in future also, so that

power sector personnel remain updated with current technology and best practices.


10

14. He stated that with increasing complexity the conflicts are bound to happen. He

highlighted the vital role of NRPC, in providing a very good platform for resolving

issues amicably and for reducing litigations. He urgedthe all the members to utilize

this forum for benefit of all.

15. HethankedHaryana Power Utilities for the efforts put by them in hosting this meeting

and for excellent arrangements for the comfortable stay of the participants.

16. Member Secretary, NRPC welcomed Additional Chief Secretary, Power, Haryana,

Chairperson, NRPC, other dignitaries and participants in the 41st NRPC meeting. He

thanked Haryana Power Utilities for making a good arrangement. He apprised the

Committee about TCC meeting, held on previous day, that there were thread bare

discussions on all the issues and consensus in most of the issues was arrived.

B. OPERATIONAL ISSUES

B.1 Revised System Protection Scheme (SPS) for 765 kV Agra-Gwalior line.

TCC Deliberation

B.1.1 Based on the recommendations of TCC a separate meeting was convened on 07th November 2017 comprising members from NRLDC, NRPC Sectt. and POWERGRID for reviewing the revised logic of the scheme presented by POWERGRID in 140th OCC meeting. The minutes of the meeting was attached to the agenda note as Annexure-B1.1.In the said meeting POWERGRID was advised to explore for


11

utilising the signals from circuit breaker (CB Open/ CB close) of both the ends of 765 kV Agra- Gwailor line for SPS.

B.1.2 POWERGRID informed that the circuit breaker (ON/ OFF) signal was being utilized from Agra end in the logic. However, that from Gwalior end was not being utilized as the purpose of the scheme was being served by utilizing the CB signal from one end.

B.1.3 Representative of NRLDC stated that even if the scheme was functioning properly in normal circumstances there are chances that the scheme may not operate in case of breaker lockout from Agra end and the line getting tripped from Gwalior end.

B.1.4 NLDC also stressed on utilizing CB signals from both the ends as Agra-Gwalior is an important inter-regional transmission line and its implementation will make the scheme even more reliable.

B.1.5 POWERGRID representative stated that though the purpose was being served with the already implemented logic, POWERGRID will implement the logic utilizing the CB signal from both the ends.

B.1.6 TCC recommend that POWERGRID will inform the logicwithinthe CB signal for both the ends.

NRPC Deliberation

B.1.7 NRPC approved the recommendation of TCC.

B.2 System Study for Capacitor Requirement in NR for the year 2019-20.

TCC Deliberation

B.2.1 Member Secretary, NRPC informed the committee that issue of conducting the capacitor requirement study at 11/33 kV level through CPRIfor 2018-19 was discussed and approved in the 37th TCC and 40th NRPC meeting. He further informed that CPRI has submitted their revised offer for the above said study and has quoted consultancy charges of Rs. 55,00,000/- for the study for 2019-20 in addition to Rs. 10,00,000/- bill raised by themfor the study conducted for the period 2017-18.

B.2.2 MS, NRPC informed the Committee that NRPC Sectt. was negotiating with CPRI so as to get the cost of the study as proposed by CPRI to be reduced.

B.2.3 He further informed the Committee that the Techno Economic Sub Group (TESG) of PSDF hasraised certain queries on the proposal submitted for PSDF funding by Haryana, UP, Punjab and J&K regarding capacitor installation by them. TESG has asked the location wise details of the capacitor to be installed, study report of DISCOMs based on which they have proposed the installation of capacitor, present voltage profile, basis of cost estimate among other details. Concerned utilities were requested to submit the details as desired by the TESG of PSDF (Minutes of the meeting is attached as Annexure-III).

B.2.4 Representative of UP stated that DISCOMshavesubmitted the above stated capacitor installation proposal directly to PSDF for funding without informing SLDC and STU


12

about the same and because of which follow-up for the same could not be done by them.

B.2.5 Representative of NRLDC also flagged the issue of bypassing of STU and SLDC by other DISCOM which was not a good practice. MS, NRPC advised for following the established hierarchy so as to avoid any such situation in future of non-informed STU and SLDC regarding any work being proposed by their DISCOMs/ other utility.

NRPC Deliberation

B.2.6 NRPC agreed that the study shall be conducted at 11/33 kV level so as to obtain the true requirement of capacitor and advised NRPC Sectt. to negotiate the cost of study for 2018-19 with CPRI.

B.2.7 NRPC concurred with the deliberations of TCC and advised utilities to adhere to the established hierarchy so that the operators of the grid are in knowledge of what was happening in their system.

B.3 Reactive compensation at 220 kV and 400 kV level.

TCC Deliberation

B.3.1 MS, NRPC informed the Committeethat the following reactors were agreed in 39th

Meeting of SCPSPNR and thereafter were approved in 37th TCC and 40th NRPC meeting:

a) TCR of capacity 500 MVAr at Kurukshetra 400 kV bus.

b) Bus Reactors at 30 no.of 220 kV sub-stations and 18 no of 400 kV level sub-stations subject to the availability of space (Annexure-B3.1 to the Agenda note). It was also agreed that these reactors shall be provided by the owner of the substations.

B.3.2 He informed that the TCR of 500 MVAr at 400 kV Kurukshetra bus was approved by the standing Committee in view of the prevailing high voltage conditions at Kurukshetra which leads to curtailing power transfer capability through Champa- Kurukshetra HVDC.

B.3.3 Representative of POWERGRID informed that the TCR at Kurukshetra was under tendering stage and LoA for the same shall be placed by June 2018 with a commissioning schedule of 24 months. He further informed that in view of the prevailing high voltage condition at Kurukshetra, for the time being a reactor of 125 MVAr is being installed at Kurukshetrawhich will be commissioned by June 2018 and another reactor of 80 MVAr shall also be installed by March 2018. It was informed to the Committee that these reactors will provide a relief of about 10 kV at Kurukshetra.

B.3.4 CTU informed that in the Empowered Committee meetingit was suggestedto get the reactors at 400 kV ISTS substationscommissionedthrough TBCB. However, these reactors being important for maintaining the voltage level of NR grid at the earliest, Ministry has been approached so as to allow POWERGRID to take the project rather than going through TBCB.


13

B.3.5 DTL informed that they have identified 6 substation of 220 kV and 1 substation of 400 kV (Mundka) voltage level for installation of reactors which shall be commissioned by December 2019. He further stated that in the identified substations for installation of reactor space constraint is therein most of the substations (GIS). On conversion of other substations from AIS to GIS, 02 more substations could be identified for installation of reactors.

B.3.6 PSTCL informed that they have submitted their proposal for installation of reactors through PSDF funding.

All other utilities wererequestedto submit detailed action plan for the installation of reactors.

NRPC Deliberation

B.3.7 NRPC concurred withthe deliberations of TCC and also requested NRPC Secretariat to write to Ministry for expediting their decision regarding the commissioning of reactors at 400 kV ISTS substations either through TBCB or through POWERGRID.

B.4.1 Representative from UPPTCL enquired whether the consent of States are being taken in Standing Committee for complete utilization of all bays.


19

B.4.2 MS, NRPC stated that this was the concern of all the States that the system is approved in standing committee with the approval of respective states, but states find difficult to match with the timeline set up for the upstreamsystemby POWERGRID and clarified that this issue has been deliberated at length in previous meeting.

B.4.3 He further informed the committee that as per the decisions in previous TCC/NRPC meeting, NRPC Secretariat has already written a letter to CERC. He further stated that in pursuance of the issue, NRPC Secretariat would submit a reminder to CERC.

NRPC Deliberations:

B.4.4 MS, NRPC briefed the Committee about the concern raised by the utilities. He stated that due to delay in the commissioning of downstream network, utilities have been charged heavily. He further told that it was the concern of all utilities as upstream assets were utilized for strengthening of the Grid, it should be charged through PoC mechanism.

B.4.5 Additional Chief Secretary (Power), Govt. of Haryana considered the concern raised by utilities and emphasized that Project and Contract management is a critical area. He further mentioned that there should be synchronism between States planning their downstream network and POWERGRID planning its 400 kV network. He told if states do not match the committed schedule with that of POWERGRID then they would be always be behind, which should be avoided.

B.4.6 Representative of HPSEB reiterated their demand,that charges should be recovered through the PoC mechanism instead of passing to utilities. He further informed the committee that the matter was discussed in the validation committee meeting where CERC representative had asked HPSEB to file the petition in CERC. Accordingly, HPSEB is going to file a petition in CERC. He requested other utilities to join them for the same

B.4.7 PCE-II, CEA stated that PoC mechanism is for all the regions hence NR constituents should not take decision whether to include charges in PoC or not. He further mentioned that this forum was not empowered to take a decision and it should be brought up to CERC.

B.4.8 CE (GM), CEA informed the committee as per the CERC order till the commissioning of the downstream elements, the utility responsible for delay shall bear the charges.

B.4.9 MS, NRPC clarified to Committee that issue was already discussed in previous TCC/NRPC meeting and it was decided that NRPC Secretariat would write a letter to CERC regarding the issue.

B.4.10 He further told that a letter was written to CERC according to a decision taken in previous TCC/NRPC meeting and citing the seriousness of issue NRPC Secretariat should write a reminder letter to CERC.


20

B.4.11 Committee agreed and approved the NRPC Secttto write a reminder letter to CERC on the subject matter.

B.5 Database of protection settings

TCC Deliberation B.5.1 MS, NRPC informed that 35th TCC/39th NRPC approved for engaging a third party

for development of Protection database with funding through PSDF in line with that of ERPC and SRPC Protection database.

B.5.2 He further informed that based on the discussions held in 34th PSC meeting, a core committee was formed to define the comprehensive Scope of the project comprising members from the utilities of NR. First meeting of the group for defining the scope of the project was held on 01.02.2018 and based on the inputs received from the members, Draft Bidding Document has been prepared by the NRPC Secretariat and will be circulated for the approval of the committee in its next meeting.

B.5.3 NRPC Secretariat has submitted the DPR of the project for PSDF funding based on the draft bidding document and the proposal of NRPC has been recommended by the techno Economic Sub Group of PSDF to the appraisal committee for its approval.

B.5.4 MS, NRPC informed that tender would be floated after finalization of the Bidding Document by the committee with the execution period of the project being 18 months.

NRPC Deliberation B.5.5 Additional Chief Secretary (Power), Govt. of Haryana, Sh. P K Das, queried about the

mode of data collection. It was informed that the relay settings data would be collected physically by visiting the substations and not automatically.

B.5.6 He further queried if the format for collection was decided to which it was informed that ERPC has already implemented the project and SRPC was implementing the same and the format was available with them.

B.5.7 Sh. P. K. Das stated that if the data was to be collected physically in a format which was already available with ERPC and SRPC, the execution period of the project which was 18 months was not justified and the same process of data collection could be done within 3-4 months.

B.5.8 PCE-II, CEA stated that relay setting data collection was not the only work involved in the project. It also consists of the process of validation of the relay settings after modeling the network and simulating the same. He stated that this process of modeling the network and validation of the relay settings would take most of the time and 18 months execution period was justified.

B.5.9 NRPC agreed to the above justification of PCE-II, CEA and advised NRPC secretariat to proceed further with the proposal.

B.6 Issue of ownership of 3x105 MVA ICT replaced by POWERGRID in place of 250 MVA ICT at BBMB, Dehar


21

TCC Deliberation B.6.1 Member Secretary, NRPC informed that in the 37th TCC and 40th NRPC meeting,

representative of POWERGRID had informed that as per the approval of 30th Standing Committee of Power System Planning of NR held on 19.11.2011, POWERGRID had to install 2 x 63 MVAr Bus reactors and replace 250 MVA ICT with 3 x 105 MVA ICT at BBMB, Dehar.

B.6.2 The commissioning detail of the said elements as under: Sl. No.

Description of Element Date of first time charging

2 63 MVAr Bus Reactor - I 12.12.2016 at 22:34 hrs

14.12.2016 Certificate issued by NRLDC.

3 63 MVAr Bus Reactor - II 28.09.2017 Yet to be declared.

Test Charged only.

B.6.3 He informed that the successful trial run certificate of the 3 x 105 MVA ICT was put on hold by NRLDC as BBMB has claimed the ownership of the ICT.

B.6.4 As advised by Chairperson, CEA in 40th NRPC meeting a separate meeting with the affected party to resolve the issue of ownership of ICT at Deharwas held on 09.02.2018 at NRPC Secretariat wherein BBMB stated that the decision of their management shall be intimated in the 38th TCC and 40th NRPC meeting.

B.6.5 Member (Power), BBMB stated that there were two issues related to the ICT installed at BBMB Dehar by POWERGRID. One was the operational issue which has been resolved as the O&M was to remain with BBMB whether or not the ownership is with them or with POWERGRID. Second issue, he pointed out was that of the ownership. He stated that the decision taken in the separate meeting held on 09.02.2018 at NRPC Secretariat needs to be shared with the BBMB partner states so that they may decide whether to obtain the ownership of the ICT by making upfront payment of the ICT along with the 15% consultancy charges to POWERGRID or to allow POWERGRID to own the ICT and let them recover their investment through PoC tariff. He requested POWERGRID to share the details of the cost which needs to be paid by BBMB for obtaining the ownership of the ICT

B.6.6 He further stated that the partner states of BBMB were raising concerns on the increased PoC charges and they shall be given some time so as to decide on the issue of owning the ICT.

B.6.7 MS, NRPC stated that PoC charges has increased for all the States as new elements are getting added in to the grid. He stated that even if the element does not get


22

installed in NR even then the charges of elements commissioned in other region are also shared by all the utilities. He further informed that POWERGRID being a revenue neutral body, only collects the charges for elements installed by them and in this situation holding back the recovery of its investment through PoC tariff by BBMB was not justified.

B.6.8 POWERGRID representative informed that all the details regarding the ICT cost has already been submitted to BBMB and shall also be forwarded again. However, he stated that till the time it was not being decided by BBMB and their partner states whether to own the ICT, POWERGRID shall be allowed provisionally to charge the tariff of the ICT through PoC mechanism. He stated that for past 8 months the tariff was on hold and POWERGRDI was bearing losses for the same.

B.6.9 Member (Power), BBMB stated that if the issue was pending since last 8 months one more month may be given to BBMB partner states and he assured that within this period the issue would be decided by BBMB and their partner states and the issue shall be resolved.

B.6.10 MS, NRPC requested BBMB to ensure that the issue gets resolved within 1 month. He further stated that whenever in a forum BBMB agrees to any issue it should consult its partner states beforehand so as to avoid any such situation in future.

NRPC Deliberation B.6.11 NRPC concurred with the deliberations of TCC and advised BBMB and its partner

States to take their decision within 1 month and resolve the issue. BBMBand other utilities were further advised that whenever any such proposal is brought by any of the agency/such type of issues/ regarding source of funding/ ownership etc. shall be discussed beforehand with their partner states.

B.7 LVRT issues of wind generation

TCC Deliberation B.7.1 MS, NRPC informed that Technical Standards for Connectivity to the Grid,

(Amendment), regulations, 2012, provided for LVRT capability for Wind generating units. However many of the generators commissioned after 15.04.2014 in Rajasthan, are not LVRT compliant. Similarly, many generators with installed capacity 500 kW or more and commissioned before 15.04.2014, also do not have LVRT facility.

B.7.2 He further informed the Committee that this agenda item was being considered in various fora of NRPC for compliance of Regulations / orders by CEA/CERC but no progress has been observed on compliance.

B.7.3 RVPNL representative again informed that the case for filing petition to RERC was forwarded to REMC wing and will be filed at the earliest.

B.7.4 MS, NRPC stated that it was the responsibility of Rajasthan SLDC to ensure compliance to various regulations and they need to impress upon the wind generators


23

so as to install LVRT at the earliest. He requested Rajasthan to call all the Wind turbine generators and sensitize them about the repercussions of non-availability of LVRT for the grid security. It was also advised to call any agency which was in the field of LVRT installation to sensitize the gathering of Wind generators.

B.7.5 Representative of NLDC stated that recently 2 incidents occurred wherein severe disturbances were observed in the grid due to non-availability of LVRT in the Wind generators. He requested Rajasthan SLDC to ensure earliest compliance to these regulations.

B.7.6 MS, NRPC proposed that the must run status to the wind generators should only be granted to LVRT compliant wind generators and non compliantwind generators shall not be scheduled and it should be the responsibility of Rajasthan SLDC for the implementation of the same. TCC agreed to the proposal and advised Rajasthan SLDC to ensure compliance to the decision.

NRPC Deliberation B.7.7 PCE-II, CEA queried Rajasthan about how in the first place the connectivity was

granted to these LVRT non-compliant wind generators. CE (GM), CEA also stated that LVRT for wind generators getting commissioned after April 2014 and connected at 66 kV and above voltage level is mandated in CEA connectivity standards.

B.7.8 Representative of NRLDC also stated that LVRT non compliance was a very serious issue and shall be resolved at the earliest for ensuring security of the grid.

B.7.9 Sh. P. K. Dasstatedthat in future all the constituent States shall not give connectivity to wind generators unless this compliance was fully met. He advised Rajasthan SLDC to give a notice to all the LVRT non compliant wind generator stating the following :

Wind generators providing them with 1 month time for compliance to LVRT, failing to which Rajasthan SLDC would be constrained to deny scheduling to these generators.

B.7.10 NRPC concurred with and agreed to the TCC deliberations.

B.8 Connectivity to Naitwar Mori HEP (NMHEP) (2X30MW) of SJVN Ltd. in Uttarakhand

TCC Deliberation B.8.1 Representative of SJVN informed that CTU vide letter no. C/CTU/N/CON/338, dated

16.10.2017 had intimated the grant of connectivity as per FORMAT CON-3 for NMHEP, wherein the transmission system required for connectivity for NMHEP is as under:

a) Naitwar Mori HEP - #Location of Mori 220/132 kV (PTCUL) substation 220 kV D/c (to be implemented by applicant along 220 kV bays at generating end).


24

b) #Location of Mori 220/132 kV(PTCUL) Dehradun 220 kV D/c (to be implemented by PTCUL)

#Mori 220/132 kV substation is not required in the time frame of connectivity of Naitwar Mori HEP.

B.8.2 He further informed that in one of the meeting held with Director (Projects), PTCUL on 06.01.2018 (to expedite the construction of transmission line) it was informed that PTCUL intends to change the location of 220/132 KV sub-station at Mori and exploring the possibility to locate the sub-station to a new location somewhere near the village Naugaon. The location of sub-station at Naugaon is also yet to be finalized by them.

B.8.3 He stated that main civil package of NMHEP has already been awarded and the Public Investment Board (PIB) while recommending the investment decision for NMHEP has expressed their concern regarding transmission infrastructure beyond Mori substation to be made available before CoD of the project.

B.8.4 He further informed that PTCUL has not made any official intimation either to SJVN or to CTU regarding their decision to change the location of substation from Mori to Naugaon and now with the location being changed primarily it would lead to delay in the execution of the project and would also increase the cost of the project as the location of new substation will require around extra 20 Km transmission line to be laid.

B.8.5 Representative of PTCUL informed that they had tried to search land in Mori but were not able to find any suitable site for the substation. Now, the land has been identified in Naugaon area and the line from Naitwar Mori HEP switchyard to Naugaon being a dedicated line to be used by SJVN, PTCUL was awaiting consent from SJVN before taking the revised proposal to CTU and Standing Committee.

B.8.6 CTU informed that they have received comment from SJVN but not from PTCUL regarding the decision to change the location of substation. He stated that with the change in location the length of the transmission line from switchyard to Naugaon substation will increase by approximately 20 Km not only for Naitwar Mori HEP but also for other projects to be constructed. Mori substation has been indicated in the plan as a pooling station and this change in location will increase the cost of all the future projects.

B.8.7 MS, NRPC stated that because of the change in location of the substation, the project was getting delayed which would also require all the approvals to be obtained afresh for the changed location. In view of the above it was suggested that a Joint inspection may be carried by PTCUL and SJVN so as to identify land in Mori to avoid the delay in the implementation of the project.

NRPC Deliberation


25

B.8.8 PTCUL representative informed that they had already surveyed Mori but were unable to find the location suitable for the substation. However, it was informed that they have identified 3 tentative locations suitable for the substation at Naugaon.

B.8.9 Additional Chief Secretary (Power), Govt. of Haryana, Sh. P K Das stated that ideally Mori may be the best location for having the substation but practically if the land was not available there was no benefit in delaying the project further and PTCUL should be allowed to go forward with the location identified by them in Naugaon.

B.8.10 To this proposal of Sh. P. K. Das representative of SJVN stated that there main concern was to avoid the delay in the project and they were not averse to the substation to be built in Naugaon if the location was not available in Mori.

B.8.11 Representative of CTU stated that Mori being a pooling station, shifting the location to Naugaon would increase the length of Transmission line from all the upcoming projects by 20 Km. He further stated that SJVN and PTCUL shall be asked to carry out joint inspection within 15 days and intimate their decision to CTU and accordingly the same shall be taken at the Standing Committee meeting.

B.8.12 NRPC advised SJVN and PTCUL to carry out joint inspection within 15 days to identify appropriate land at Mori and if no land could be identified at Mori the proposal shall be moved forward with location as identified by PTCUL so as to avoid any further delay in the project.

B.12 Non availability of data from major PSTCL Sub-stations


34

B.12.1 NRLDC representative informed that data from critical PSTCL substations like 400 kV Talwandisaboo, Muktsar and 400 kV Nakodar was not available at NRLDC since long. It was due to faulty/burnt Cards of Communication equipment at 220 kV Moga sub-station of PSTCL. Cards have burnt at least Eight (08) times in last 2 years. However, no action has been taken by PSTCL.

B.12.2 NRLDC also informed that PSTCL had only replaced earthing instead of third party audit (by SAMEER - Govt. of India) as discussed during the 11thTeST meeting. After the discussion in last meeting, cards has burnt 2 more times at Moga 220kV (PSTCL) and caused non-receipt of at least 5-6 sub-station data routed through that direction.In its 12th TeST meeting held on 22.12.2017, the TeSTSub-committee expressed its concern on non-availability of telemetry from a number of stations due to this issue. The sub-Committee advised representative of PSTCL to get the earthing audited by third party at the earliest

B.12.3 In the meeting, NRLDC informed that Data was being received from above PSTCL stations w.e.f. 21.02.2018. PSTCL representative informed that the third party audit of earthing had been completed and reports were submitted to POWERGRID. POWERGRID informed that they were studying the report and further required action, if any, would be intimated to PSTCL and NRPC Sectt.

NRPC Deliberations

B.12.4 NRPC noted the TCC deliberations. Member Secretary NRPC requested PSTCL and other constituents to ensure 100 percent telemetry from all stations.

B.13 Shifting of Rihand-III to WR

B.13.1 NRLDC representative gave the background as given below: As per discussion at NRPC level in 31st Standing committee meeting and in 29th

standing committee of WR it was decided that Rihand-III(Unit#5 & 6 =2*500MW) would be shifted from NR to WR by connecting through Rihand(III)-Vindhyachal PS 2XS/C lines after commissioning of 3000 MW HVDC Champa-Kurukshetrabipole to relieve line loadings in Singrauli-Rihand-Anpara complex. Since Champa- Kurukshetrabipole is in operation since Sept 2017, shifting of Rihand-3 to WR was proposed by POSOCO, a set of guidelines were finalized based on studies and the same were circulated to all concerned. Based on the studies it was decided that synchronization shall be done when angular separation between Rihand and Vindhyachal Pool is minimum (within 3 degrees), with Rihand bus leading because power was supposed to flow from NR(Rihand-III) to WR(Vindhyachal). Further, as there was shortage of oil used for start-up purpose and since bus sectionaliser was available at Rihand end, it was decided that the changeover be done online without taking the units out. B.13.2 After checking of station auxiliaries, lines were idle charged from both ends one by

one to ensure that lines and terminal equipments are healthy. Confirmation regarding protection setting and PLCC tuning was taken from both ends.


35

(i) As per the guidelines circulated, first Synchronization was attempted on 27-Nov-2017. Lines were charged from Vindhyachal PS end. However, lines could not be synchronized at Rihand Stage-III end because of problem with the synchronizing trolley at NTPC Rihand end & hence exercise was postponed.

(ii) Second attempt was initiated on 28-Nov-2017. 400 kV Rihand (III)-Vindhyachal PS Ckt-1 was idle charged from Vindhyachal PS at 12:06Hrs/28.11.2017. In order to reduce the angular separation between Rihand&Vindhyachal:

HVDC Champa-KurukshetraBipole power flow was increased (WR to NR)

HVDC Vindhyachal back to back power order was changed from 100 MW (NR to WR) to 250 MW towards NR

Power order on HVDC Rihand-Dadri was reduced Generation in Rihand was increased

B.13.3 Shifting of Rihand Stage-III units (Unit No-5, 6) in the online mode was successfully

executed with coordination in real time between POSOCO, NTPC and Powergrid (WRTS-II).

After shifting of Rihand stage-III units, NTPC reported problem of excessive Vibrations in GTs of Rihand stage III when RihandDadri one pole was operating in ground return mode. In 142nd OCC Meeting, actions taken by utilities for resolving this issue of vibrations in Rihand stage-III units were discussed:

NLDC requested planners, CTU, CEA (NPC) to provide assistance for studies in this regard and asked them to share their experiences regarding the same.

NRLDC requested NTPC for old data (including information about any vibrations) when only few units of Rihand (say Rihand-I/ Rihand-II) were commissioned and Rihand-Dadri HVDC bipole was operated in monopolar operation. Further, information regarding earthing grid at Rihand 1, 2 & 3 was also asked.

In this regard, NTPC representative informed that they would get assessment of earthing system at Rihand soon.

B.13.4 NTPC asked about the start-up procedure in case of grid failure. For the start-up procedure for Rihand-I, II & Stage-III Units in case of failure of any of Western/ Northern region, it was decided in 142nd OCC Meeting that normalisation process may be started with extension of power using bus coupler at Rihand after taking consent of NRLDC similar to using AC bypass link at VindhyachalBtB as decided earlier.

B.13.5 NRLDC representative also informed the house that Shifting of Rihand-3 has helped in relieving line loadings in Rihand-Singrauli-Anpara complex. However, N-1 contingency of lines from Anpara (765 kV Unnao, Obra, Mau, Sarnath D/C) may still result in critical loadings of other lines in the complex. Therefore, early commissioning of 765 kV Anpara D Unnao needs to be expedited to relieve line loadings in this complex.


36

B.13.6 NRLDC representative also mentioned that since, Rihand-III is now connected to WR, outage of inter-regional lines (Rihand III Vindhyachal pool) would be taken care by NLDC in consultation with NRLDC and WRLDC. In case of constraint in Vindhyachal complex, the curtailment of Rihand stage 3 would be done similar to other stations in Vindhyachal complex. Scheduling of Rihand-III would be continued by NRLDC.

B.13.7 NRLDC representative informed that based on approvals in OCC, the System Restoration Procedure has been modified to include utilisation of Rihand stage 3 and Rihand stage 2 bus coupler in the similar manner as AC bypass at Vindhyachal back to back.

B.13.8 However, NRLDC representative emphasized that the issue of higher vibration is Rihand stage 3 units during mono pole ground return operation of Rihand-Dadri HVDC need to be addressed. He said that as decided in OCC meeting, NTPC shall come out with past data as well as grounding measurements at all the stages of Rihand.

B.13.9 NTPC representative informed the forum that as per report from field officers, they have no past history such vibrations at any of the stages during mono pole ground return HVDC operation.

B.13.10 TCC recommended formation of a committee with members from POWERGRID, CTU, CEA, NTPC, POSOCO and NRPC to look into the issue of high vibrations during mono pole ground return operation for corrective actions.

NRPC deliberation

B.13.11 NRPC noted the delibration held in TCC and approved the formation of Committee recommend by TCC.

B.14 AGC Implementation TCC deliberation

B.14.1 NRLDC representative informed the house that Honble CERC order dated 13th October 2015, highlighted the need for implementing Automatic generation control in machines. In this direction, first pilot project of Automatic Generation Control (AGC) in India has been officially commissioned by POSOCO and NTPC. This pilot project is controlling the generation of Dadri Stage 2 (980 MW IC) with reference to the Area Control Error (ACE) of Northern Region from 04.01.2018 onwards.

B.14.2 Further, Honble CERC has asked POSOCO to replicate similar AGC pilot projects in other regional grids. Implementation of AGC is crucial at this juncture as it would help adding of renewable capacity in the grid which is happening at an unprecedented


37

scale and speed (both large-scale grid connected projects as well as several distributed energy resources primarily in the form of rooftop solar).

B.14.3 The NRLDC representative also mentioned that there is separate agenda item from NPC on the subject and a detailed presentation on AGC would be made on that agenda.

B.14.4 TCC noted the development. NRPC deliberation

B14.5 NRPC noted the information

B.15 Summer Preparedness 2018

B.15.1 NRLDC representative gave a detailed presentation on the summer preparation. He gave regional and statewise trends of Demand (MW) and Energy for last 4-5 years and based on these drew conclusions on rise in demand with rise in temperature, demand increase trajectory etc. He also put forth the issues specific to summer/monsoon months for Northern Region. He stated that the summer and monsoon months are very crucial months for system in view of highest demand being met in NR during these months. He presented the high temperature forecast by Indian Meteorological Department (IMD) for summer months wherein about 1-2 degrees higher temperatures have been predicted in NR while the same around 1 degree higher in the rest of country. He also mentioned that the hydro generation at present is lower than the past year though reservoir position is almost similar to last year. The representatives of hydro stations also informed that house that this these is less snow and therefore hydro generation is on lower side.

B.15.2 He mentioned following characteristics of summer/monsoon power system operation of NR:

High Demand High loading/ High Reactive Power Requirement High hydro generation Thunderstorm during summer Silt during Summer/Monsoon Transfer Capability violations

On each of the above points, NRLDC gave past statistics to highlight the issues. He also stated that fuel shortage this year combined low hydro generation could be difficult and therefore, requested all the utilities to buildup enough fuel stock for increasing the internal generation in NR and for also for keeping reserves in the each of control area.

B.15.3 He also mentioned following Action plans: Meticulous load forecasting and portfolio management TTC/ATC calculations, keeping margins, Network Tower strengthening, New network commissioning Keeping fuel reserves Keeping reserves (generation in control areas for contingencies)

Following was agreed during the meeting

B.15.4 Weather Monitoring & Load forecast All the entities would endeavor to forecast their loads meticulously in advance for

their portfolio management plans and also on day ahead and real time basis taking into weather into account. They would also be utilizing the IMD (in coordination with POSOCO) developed dedicated website for Northern region (link: http://amssdelhi.gov.in/NRLDC/main/MAIN.html) for getting weather warnings and other meteograms, Radar images etc. The impact of lunar eclipse on 31.01.2018 and consequent very large deviation from schedule by states (specially of Southern Region) was also discussed to highlight the impact of social events of electricity consumptions and therefore factoring them in load forecasting is essential.

B.15.5 TCC also advised the utilities to take actions for reducing the forecast errors. J&K PDD was also requested to start sharing forecast with NRLDC at the earliest as mandated in IEGC and agreed to earlier TCC/NRPC meetings.

B.15.6 Thunderstorm/Load crash during summer: Based on past data presented by NRLDC on load crash, tower collapses and very

longer time for revival of lines, the TCC emphasized: Tower strengthening and keeping availabi
