C.1 TESTING OF SPECIAL ENERGY METERS (SEMs)

The above agenda point was first discussed in the 5th NRPC meeting

held on 14.07.07 and 6th NRPC meeting held on 25-10-2007. During 6th meeting, POWERGRID was requested to adopt international competitive bidding process to find an international vendor to carry out on-site testing of accuracy of CTs / CVTs of 220 kV & above rating along with that of SEMs, as stipulated in CEA (Installation and Operation of Meters) Regulations.

During the 7th NRPC meeting held on 20th December 2007 POWERGRID informed that Global Expression of Interest had already been floated by them, and it was due for opening on 20th December, 07. Outcome of the same would be informed later.

The matter was also discussed during the 7th TCC and 8th NRPC meeting held on 24th and 25th April 2008. POWERGRID informed that in response to the bidding process by them only four bidders had submitted the bids. Except CPRI other bidders had submitted conditional bids. It was decided in the TCC meeting that testing of SEM should be done along with CT & CVT. However, during the NRPC meeting, POWERGRID was insisting for written clarifications from CEA as to whether SEMs are to be tested along with CT/CVT. NRPC agreed to the suggestion of POWERGRID and also approved the decision of TCC on the subject.

During the 9th NRPC meeting held on 01.07.2008 it was decided that

Member Secretary, NRPC would find out from CPRI as to whether any proposal had been sent to MoP for clearance and sanction of requisite fund to establish CT/PT testing facility in the country. For interpretation of regulation, he requested Member (Grid Operation), CEA to give clarification on this issue as soon as possible.

CEA had informed that in view of the difficulties faced the provision of CEA’s Regulations on “Installation and Operation of Meters” regarding onsite testing of meters and associated CTs/CVTs/VTs is under consideration of CEA.


As decided in the 9th NRPC meeting MS, NRPC had taken up the matter with CPRI vide letter dated 29.7.2008. The CPRI vide their letter dated 05.08.2008 had informed that Ministry of Power, GoI had approved their project for establishment of mobile test laboratory. The same is expected to be operational by April 2010. The status of establishment of mobile test laboratory for CT/CVT as informed by CPRI had also been intimated to CEA.

The matter was discussed in the 9th Commercial Sub-committee meeting held on 05.09.2008. In view of time frame of operationalization of mobile test laboratory for CT/ CVTs by CPRI, NRPC secretariat had proposed to start the testing of SEMs alone in the first instance. The sub-committee members did not agree to this proposal and suggested that till the Regulations of CEA on Installation and Operation of Meters was modified , the testing of SEM without CTs/CVTs would be kept pending.

The matter was again discussed in the 10th NRPC meeting held on 30.09.2008. It was decided that CEA would give their decision within two months. CEA’s decision in this regard would be final and NRPC would proceed accordingly.

CEA vide letter dated 14.11.2008 clarified that the interface meters installed in the system of 220 kV and above may be tested separately till such time Indian Standard applicable to the required accuracy Class is released or facility for testing of meters along with CTs and PTs are developed.

The testing Special Energy Meters could, therefore, be taken up by POWERGRID.

C.2 OVERHEAD CHARGES ON AMC CHARGES (RELATING TO ULDC)

The issue of overhead charges was discussed in the 4th meeting of NRPC held on 8th February 2007, 6th meeting of NRPC held on 25-10-2007 and 7th NRPC meeting held on 20th December 2007. Finally, in the 8th NRPC meeting held on 25.04.2008 it was decided that 8% overhead charges could be given to PGCIL for AMC of SCADA /EMS system. For overhead charges on other AMCs existing arrangement would be continued.

HVPNL have informed that the present MoU for AMC of wide band communication equipment installed under ULDC-NR project is expiring on 15th September 2008. POWERGRID has forwarded a “side letter” to the MoU extending the validity of the same for a period of 10 years commencing 16.3.2004 i.e. for another 5 years without revising the over head charges for the AMC. The matter was referred back to PGCIL but they had declined to amend the charges as requested. HVPNL requested that as per discussions and decisions held in Northern Region Power Committee meetings, POWERGRID should honour their commitment and revise the overhead charges for AMC of various packages after the expiry of MoUs to be at par with the overhead charges for SCADA/EMS packages i. e. @ 8 %.


The above issue raised by HVPNL was discussed in the 9th Commercial Sub-committee meeting held on 05.09.2008. POWERGRID had not agreed with the interpretation of HVPNL regarding the decision taken in the NRPC meeting and had not accepted the proposal to reduce the rate for overhead charges for other AMCs to 8%. The Sub-committee members decided to refer the matter to TCC/NRPC for decision.

Accordingly the issue was discussed in the 10th NRPC meeting held on 30.09.2008 and following decisions were taken:

a) Northern Regional Power Committee decided that in view of important

operational requirement, their AMC should remain centralized and POWERGRID should do it.

b) POWERGRID should calculate actual overhead charges on these AMC

as one time exercise and round it off and be charged. States should pay accordingly.

c) NRPC could fix percentage for overhead charges on AMC of ULDC

and POWERGRID would take up with their Board. In case Board agrees then State would pay accordingly and in case Board did not agree the matter would be taken up before CERC.

POWERGRID may update the Committee in the matter.

C.3 DULHASTI H. E. PROJECT -SUBMISSION OF STATE GOVT GUARANTEE

NHPC in the agenda item discussed during the 8th NRPC meeting held on 24/25th April 2008 have stated that PDD, J&K and DISCOMs of Rajasthan signed the PPA for Dulhasti HEP with the provision of tariff to be applicable as fixed by CERC from time to time, whereas Punjab, Haryana, Delhi, UT of Chandigarh, Uttrakhand and Uttar Pradesh have signed the PPA with the provision of tariff on “Back Loaded Tariff Model”.

In accordance with clause 9.3 of the PPA signed with the beneficiaries with the provision of tariff on “Back Loaded Tariff Model”, these beneficiaries were required to arrange State Govt. Guarantee, as security for the liquidation of the outstanding amount against any default in payments and / or backing out from the PPA. During the 8th NRPC meeting held on 24/25th April 2008 it was decided that the States would expedite State Government guarantee and in case it is not possible to submit the same, the concerned beneficiary State would give their alternate proposal within one month.

As no States had given State Government guarantee to NHPC, the issue was raised by NHPC during the 9th NRPC meeting held on 1.7.2008. It was decided that concerned States would give either State Government


guarantee or in case of inability to do so, give NHPC an alternative plan by 31st July 2008.

Since only NDPL had submitted an alternate proposal to the NHPC for its

consideration, NHPC again raised this issue in 10th NRPC meeting held on 30.09.2008. During the 10th NRPC meeting it was decided that States would send their alternative proposal to NHPC within 60 days other wise States should adopt tariff as determined by CERC.

NHPC have now informed that Haryana and BSES-Rajdhani have also

submitted their option for switching over to tariff as determined by CERC. NHPC further stated that since no communication have been received from other beneficiaries, it is presumed that they are ready to adopt tariff as determined by CERC as decided in the 10th NRPC meeting.

Punjab, UT of Chandigarh, Uttrakhand and Uttar Pradesh may kindly

confirm.

To be constructed by HVPNL at their own cost

Bhiwani-Rohtak 400kV D/C Jind-Hissar HVPN 400kV s/s D/C

(iv) 400 kV S/S at Sohawal with 2x315 MVA ICT 2 nos. to be established

by LILO of both the circuit of Balia - Lucknow 400 kV D/C line. The above s/s would meet the load demand of Faizabad area of UP..

(v) Saharanpur 400 kV S/S with 2x315 MVA ICT to be established by LILO

of both the ckt of Dehradun - Baghpat 400 kV quad line The above s/s would meet the load demand of Saharanpur area of U.P.

(vi) Shahjahanpur 400 kV S/S with 2x315 MVA ICT to be established by

LILO of both the ckt of Lucknow (PG) – Bareilly (PG) 400 kV D/C line. The above s/s would meet the load demand of Shahajahanpur area of U.P. This regional s/s has been proposed in lieu of Hapur s/s agreed earlier under regional scheme. Now 765/400/220 s/s at Hapur would be established by UPPCl.

(vii) Creation of new 220/400 kV S/S at Jaipur (South) with 2x500 MVA

transformer to be created by LILO of Agra - Jaipur line at Jaipur. The new substation at Jaipur would help in mitigating the heavy loading on the existing 400 kV S/S at Jaipur

(viii) RVPNL intend to establish three nos. new 220 kV S/S around Jaipur at

Indra Nagar, SEZ-1 and Bagru (by 2009-10 time frame). The above S/S would be established in the following manner

Name of the proposed 220 kV Grid Sub-station

Proposed Transmission system

Indra Nagar, Jagatpura(Jaipur) 220/132 kV , 1x100 MVA

By LILO of one circuit of the Bassi - Heerapura 220 kV D/C line

SEZ-1 (near Jaipur) LILO of 220 kV Jagatpura -Heerapura section of Bassi –Heerapura line

Bagru LILO of Bassi Phulera line The expenditure to be incurred for the LILO would be totally borne by RVPNL and they also like to take up the maintenance of the entire


Bassi - Heerapura line. The proposal was discussed and concurred by the Standing Committee of NR in its 26th meeting. However, RVPNL would required to finalise the modalities regarding maintenance of Bassi –Heerapura line with Powergrid.

(ix) Powergrid stated that RVPNL has indicated non-availability of space/R-

O-W problem for taking up 220 kV D/C line from Sikar 400 kV PGCIL to 220 kV Sikar RVPNL which was agreed as a part of transmission system for absorption of power from Sasan/ Mundra UMPP. It was stated that instead of the Sikar(PG) - Sikar 220 kV D/C line the existing 220 kV D/C line from Sikar - Ratangarh of RVPNL may be LILOed at Sikar (PG). The proposal was agreed by the Committee.

(x) In the 26th meeting of the Standing Committee of NR, Creation of

220/400 kV 2x500 MVA S/S at Ramban by LILO of the 400 kV line from Kishenpur to New Wangpoh – Wagoora to evacuate power from Chenab basin project in J&K as well as for disbursal of power at 220 kV in Jammu region was discussed. However, PDD J&K was of the view that Jammu area needs a feed at 400 kV as existing 400 kV S/S at Kishenpur does not have adequate space for expansion. Since Ramban is in the North of Jammu and it would be difficult from there to take line to Jammu at 220 kV. As such, a 400 kV S/S at Samba at the first instance should be considered and a pooling station at Ramban could be considered with the generation projects at Chenab basin. The proposal was agreed and it was decided that a 400/220 kV S/S with 2x315 MVA ICT would be created at Samba, Jammu. However, the feeding line for the S/S with the 400 kV regional network would be decided after a survey of the area by PGCIL along with PDD, J&K engineers.

NRPC may concur the above New Regional Schemes

4. Power Evacuation from Parbati and Koldam HEP 4.1 Parbati Koldam Transmission Company Limited (PKTCL), a joint venture of

Reliance and PGCIL would be developing part of the evacuation system of Parbati and Koldam HEP. The scope of work entrusted with M/s. PKTCL is as under:-

S.No. Transmission lines Voltage level and line length 1. Parbati - Koldam 400 kV Quad a. Single Circuit line -I 75 km b. Double circuit line -II 3.5 km c. Single Circuit line-II 75 km 2. Koldam - Ludhiana 400 kV D/C triple snowbird,

150 kms. 4.2 The evacuation system from Parbati-II/III, Koldam and Allain Duhangan and

Malana II HEP was planned in a composite manner and it was proposed to


establish a pooling station at Panarsa, where power from Allain Duhangan and Malana II HEP was proposed to be pooled. However, due to delay in coming up of Panarsa pooling station for ensuring power evacuation from Allain Duhangan, 220 kV D/C line from Allain Duhangan to Nalagarh was agreed. Power from Malana-II was also to be evacuated through the same line by creating 220/132 kV s/s on one of the circuit.

4.3 In view the delay in commissioning of Parbati-II HEP and also the power

evacuation requirement from the Chandrabhaga Basin projects in Himachal Pradesh, the evacuation system and the time frame for the works were reviewed and after discussion the above proposals as in para 4.1 were agreed by the 26th SCM with following stipulations:

(i) M/s PKTCL in consultation with HPSEB and CEA would survey the

corridor and identify the stretches between Panarsa and Koldam where Parbati-Koldam 400kV 2xS/C lines would need to be constructed as D/C line.

(ii) The commercial operation date (COD) of 400kV D/C Koldam -

Ludhiana line should be nine months after the commissioning schedule of Koldam HEP but not later than commissioning schedule of Parbati-II. For finalizing the COD of Koldam - Ludhiana line, NTPC would inform the realistic scheduled date for Koldam HEP and NHPC would inform possible date of commissioning of Parbati-II HEP. If NTPC confirms March 2011 as commissioning date for Koldam HEP, COD of Koldam-Ludhiana line could be December 2011 without the need of any indemnification for the Koldam-Ludhiana line.

(iii) Parbati-III-Panarsa-Koldam section of one of the two S/C lines between

Parbati-II and Koldam would be commissioned matching with Parbati-III HEP and the balance portion of the line between Parbati-II and Parbati-III and the second line between Parbati-II and Koldam (via Panarsa) would be commissioned matching with Parbati-II. For retaining the feasibility of constructing the second S/C line at a later date without the need of closing Parbati-III generation, the Parbati-III – Panarsa section and the two circuits connecting to Parbati-III would be on separate towers without any D/C portion.

NRPC may discuss and concur. PKTCL would be approaching for

signing of BPTA and the same should be done expeditiously to ensure that the works are taken up at the earliest for timely completion.

5. Power evacuation system from Sainj HEP (100 MW) by HPPGCL 5.1 The generation at Sainj HEP would be evacuated through132 kV D/C and

injected into Parbati II/III transmission system by creating a 132/400 kV sub-station which could be connected at 400 kV through a 400 kV LILO from Parbati-II – Parbati –III 400kV S/C line or through a 400 kV S/C line either to Parbati –III or to Parbati-II. In the second case one additional 400 kV bay would be required either at Parbati-III/Parbati-II. HPSEB informed that since


Sainj was in the upstream of Parbati II PH, it would be better to create the 132/400 kV sub-station near Parbati-II and the 400 kV S/C line from 132/400 kV S/S to Parbati-II. The matter was discussed and it was decided that NHPC would review the availability of space for additional 400 kV bay at Parbati II as well as Parbati III and intimate the position to CEA as well as HPSEB. Further, HPSEB would carry out site survey to suggest the proposal taking in to account these inputs.

NRPC may please note.

6. Proposal for loop in loop out of 220 kV Jullundhur - Hamirpur line near Gagret 220/132 kV S/S of Himachal Pradesh

6.1 HPSEB had proposed to loop in loop out one circuit of the 220 kV Jullundhur -

Hamirpur Central sector line at their Gagret 220/132 kV S/S to meet the load demand in that area. It was informed that considering distribution of load in both the Jullundhur - Hamirpur D/C line after the loop in loop out, it was advisable that HPSEB may consider loop in loop out of both the circuit instead of one circuit as proposed. The matter was agreed by HPSEB as well as by the 26th Standing Committee of NR.

NRPC may please note.

7. Requirement of shifting of Sasaram HVDC module. 7.1 Sasaram HVDC module was proposed to be shifted to Kolhapur under the

SR-WR scheme with 50% transmission charges agreed by SR but WR agreeing to only 25% charges and asking NR to share the balance 25%. The proposal was earlier discussed in the 25th meeting of the Standing Committee but NR constituents had not agreed for sharing transmission charges for SR-WR link without having firm power allocations from that route. Since the Sasaram HVDC module was to be bypassed and shifted to other location to accommodate creation of 765 kV S/S at Sasaram, NR constituents could give their consent providing assurance for 25% transmission charges to POWERGRID and CEA would discuss the issue in Southern Region where IPPs have sought open-access which would require transmission through SR-WR route. Once the IPPs in SR agree to share the balance 25% transmission charges for the SR-WR inter-regional link, the NR constituents would be relieved of the responsibility of payment of transmission charges for SR-WR link.

7.2 In view of urgency to shift HVDC b-t-b module from Sasaram to create space

for 765kV, the proposal was agreed by all the constituents of NR. RVPNL suggested that alternate of shifting HVDC b-t-b to Bhinmal could also be considered. The proposal was deliberated in details in the 26th SCM of NR and it was pointed by CEA that Bhinmal does not appear an appropriate location for the HVDC. Further, acquisition of alternative land at Bhinmal would be required which would be time consuming. As PGCIL had already initiated action for procurement land at Kolhapur, it was decided that HVDC


module from Sasaram would be shifted to SR-WR system. The constituents of NR agreed to the proposal of CEA.

NRPC may concur the above Proposal.

C.5 OUTSTANDING ENERGY CHARGES OF GENERATING COMPANIES (NHPC):

NHPC have informed that on account of energy supplied upto 31st

October 2008 and payments received upto 30th November 2008 an amount of Rs. 121.88 crore (including Rs. 2.34 crore towards surcharge) is outstanding against PDD, J&K and Rs. 44 crore (approx.) against UPPCL. NHPC requested these beneficiaries to liquidate the outstanding dues urgently.

The matter was discussed in the 10th Commercial sub-Committee meeting held on 12.12.2008. J&K and UP assured to liquidate the dues of NHPC.

J&K and UP may update the position.

C.11 OVERVIEW OF GRID OPERATION

C.11.1 Power Supply Position

• The Actual power supply from Oct. 08 and Nov. 08 is enclosed at Annex-IV. NR had peak power shortage of around 12.2 % during Dec. 08 (till 21st). Energy shortage in this period was in the range of 11.6 to 12.9 %

• The anticipated power supply position from Jan. 2009-Mar. 09 as per mid term review of LGBR 2008-09 is enclosed at Annex-V. It may be seen that for the next three months, the Region would experience shortage in the range of 15.5 % to 21 % in peaking power and in the range 20 - 23.2 % in energy terms.

• The States, which are expected to experience high shortage, include Punjab, UP, Uttarakhand, J&K, Rajasthan and Haryana. They should take appropriate action to match their supply and load and should not overdraw from the Grid and adhere to CERC order(s).

• The matter was discussed in 8th, 9th, and 10th NRPC meetings held on 25.04.2008 at Udaipur, on 31.07.2008 at Leh and on 30.09.2008 at Jaipur respectively and it was decided that no constituents would overdraw at frequency 49.0 Hz or below. But the self-discipline is not working. Matter was also taken up by Member secretary, NRPC with constituents, particularly Rajasthan, UP and Delhi, on violation of IEGC in the month of Oct 2008. Inspite of all efforts, there is no restraint shown by constituents.

• CERC has issued directions dated 16.10.2008 for considering imposition of penalty of Rs. One lakh for each time block of over drawal when frequency is less than 49 Hz under section 29 of Electricity Act, 2003. Further, RLDCs have been directed to report block-wise violations by each utility at grid frequency less than 49 Hz. Date/ block wise overdrawl details of various states below 49 Hz during Oct. 2008 are enclosed at Annexure-VI

• Constituents have been separately requested to manage the shortages by arranging bi-lateral assistance from outside region and maximization of generation as well as suitable demand management measures and statutory / notified load restrictions. Members may like to deliberate.

C.11.2 Frequency profile for Oct., Nov. and Dec. (till 21st) 2008 • Annex-VII indicates details of frequency profile of the month of Oct., Nov.

and Dec. 2008 (till 21st). It is desirable that NR constituents should maintain the self-discipline by restricting over drawl and help in keeping frequency under permissible zone.

Members may like to deliberate.


C.11.3 UF and df/dt Relays

Performance of UFRs The already installed UFRs are not giving sufficient relief. The reported relief is placed at Annex-VIII Provision of Additional UFRs/Df/dt relays in NR Chairman, NRPC advised the constituents in 7th NRPC meeting to install 30% additional UFR so that sufficient relief is available in the Grid. All the constituents had agreed for the same. In the 33rd OCC meeting held meeting on 19.12.08, Constituents have submitted following details: (i) Rajasthan: - RRVPNL intimated that they are procuring 52 nos. UFR

and 17 nos. df/dt relays. The tender has been opened. The Relays would be installed by 31st March 09.

(ii) Punjab :- PSEB stated that additional 25 nos. UFRs would be installed

C.11.4 Massive tripping on 20/21st December 2008 Northern Grid experienced a massive fog related tripping on 20- 21st Dec. 08, when around 30 Nos. 400kV & 7 Nos. 220kV lines had tripped but with the efforts of operators of NRLDC, SLDCs and co-operation of all constituents, the Northern grid remained intact with the NEW grid. Crisis Management Group under the Chairmanship of Member (GO&D), CEA, held a meeting on 22.12.08 at NRPC New Delhi and the following decisions were taken : -

1. The process of insulators cleaning should continue by all the constituents till March 2009 and increase the frequency of cleaning at critical locations.

2. Constituents shall expedite the replacement of insulators by polymer/antifog on priority in critical stretches of 400kV and 220kV lines.

3. All incidents of auto-reclosures / tripping shall be analyzed by the concerned constituents and details of these trippings and analysis shall be sent to NRPC/NRLDC along with the disturbance recorder (DR) and event logger printouts.

4. Operators at all substations, generators etc. shall adhere to the instructions of NRLDC/SLDCs immediately during contingency condition. Accountability should be fixed for non-adhering to the instructions of NRLDC’s/ SLDC’s in emergency conditions.

5. UPPTCL to close the jumper at Gazipur between 220kV BTPS- Noida-Gazipur line and Gazipur-Sahibabad line within 24hrs

6. Reactors at Bareilly (POWERGRID), Moradabad, Gorakhpur, Sarnath, and Bareilly (UPPTCL) should be revived at the earliest.

7. All generating stations shall absorb MVAR up to their capability to control the high voltage conditions.

8. POWERGRID shall install temperature and humidity transducers at designated locations within a month.

9. To control high voltage at Dadri Bus, minimum capacitor bank shall be kept out of circuit by POWERGRID when both poles of Rihand - Dadri HVDC bipole are out.

10. All effort shall be made by the constituents to maintain event logging system and communication network so as to capture the events during such crisis.

C.12 Extremely slow Progress of installation of Shunt Capacitor According to the capacitor study made by NRPC Secretariat for capacitor requirement in F.Y. 2008-09, new capacitors to be added by the states were worked out as 6714 MVARs, as per enclosed Annexure-IX. The annexure also indicates capacitor installed by various states up to Nov. 2008. It may be seen that UP needs to install around 1868 MVARs, J &K 1173 MVARs, Haryana 1402 MVARs, and Punjab 863 MVARs. There is extremely slow progress of installation of new capacitors by above constituents. HVPNL


stated that they are procuring about 650 MVARs capacitors and DISCOM about 300 MVARs capacitors in their system by June 09 UPPTCL was requested to provided capacitors particularly in NAPS area as areas around NAPS continuously faces low voltage affecting the stability of nuclear plant, particularly at 220 kV Autrauli sub station of UPPTCL, from where 2 x 100 MVA load of Aligarh is fed and no capacitor installed. Also over 2000 MVARs capacitors are lying faulty which needs to be restored particularly by UP and Punjab. At Khurja (UP) 2 x 40 MVARs are faulty since long and so is condition of Muradnagar, Harduaganj etc. The states, which are lagging in installation/ revival of capacitors, are facing low voltage problem. They need to prioritise the installation of capacitors in the location experiencing low voltage. Members may like to note / deliberate.

C.13 Enhancing availability and curtailing Overdrawal by the constituents

In the last NRPC meeting, Chairman NRPC suggested that NRPC Secretariat should bring a separate agenda point on measures to be taken to enhance availability and curtails overdrawl by the constituents. Constitutes were requested to give their feed back to NRPC Secretariat. Some of the points may be considered:

Planned shut down schedule of machines should be adhered to—particularly during mid Feb.- March – mid April and Oct.-Nov.- mid Dec. every year.

Optimum utilization of state generation and preparation and implementation of state LGBR.

Increasing the generation of state sector during peak hours. Capacitor installation to improve voltage profile particularly for irrigation

loads (U.P, Punjab, Haryana and Rajasthan), this will increase the efficiency of pumps, and reduce the system losses.

Forecasting of next days demand and preplan the cuts accordingly for matching with the schedule.

Energy conservation should be encouraged. Use of incandescent lamps may be discouraged and incentive scheme for use of CFLs scheme may be encouraged.

Rotational load shedding Scheme to be introduced to manage the load. Measures need to be taken to increase off peak to peak ratio to flatten

the load curve of the state.

Members may like to note / deliberate.


C.14 Report of Inquiry Committee on Grid Disturbance in Northern Region on

7th and 9th March 2008.

A grid disturbance had occurred in Northern Region on 7th and 9th March, 2008 and CEA vide its order no. 5-41(04)/ Secy. / 2008/ 40 dated 13.03.08, constituted an Inquiry Committee under the Chairmanship of Member (GO&D), CEA along with members from NRLDC, BBMB, POWERGRID, DTL, HVPNL, UPPTCL, CEA, Indian Railways and NRPC to enquire into the incident and suggest remedial measures. A brief summary of the Report is given below: Power supply in Delhi and neighbouring constituent States of Northern Regional Electricity Grid was severely affected on 7th and 9th March, 2008 due to tripping of a large number of important transmission lines in midst of dense foggy weather conditions resulting in widespread disruption of normal life and railway traffic. On both these days, tripping of transmission lines started at around midnight and position worsened with the passage of time reaching the critical situation during 0700 - 0800 hours. The emergent conditions were handled by the northern regional and state grid operators with utmost care and meticulous management of the generation and power flow to prevent cascading failure. The severity of the grid incident could be gauged by the fact that there were 204 lines of voltage level of 220 kV and above, were affected on 7th March 08 and 141 lines of voltage level of 220 kV and above, were affected on 9th March 08 There was a loss of thermal generation of about 3670 MW on 7th March, 08 and 2355 MW on 9th March, 2008. The loss of load amounted to 2000 - 6000 MW due to these trippings. The severely affected States were Delhi, Haryana, Punjab, Uttar Pradesh and Rajasthan. Around 1000 -1500 MW of the surplus power in the Northern Region due to loss of load was exported to neighboring regions. With the rise in temperature during the day, the situation started improving with the restoration of lines at around 0930 hours and power supply was restored near normal conditions by noon. The detailed recommendations of the Committee to avoid reoccurrence of such disturbance in future and for safe and secure operation of the Grid are elaborated at para -11 of the Report (enclosed at Annexure–X for ready reference) . The major recommendations are: -

Implementation of Recommendations of Inquiry Committee on Grid Incident of 27th January, 2007

Periodic cleaning of insulators of lines especially during pre-winter every year

Replacement of existing insulators by Polymer / Anti fog Insulators in high pollution stretches.


Alertness during high Relative Humidity (RH) and Low Temperature conditions.

Ensuring Railways supply reliability. Operation of Minimum filter bank at HVDC Rihand –Dadri Bi polar Pollution control of diesel vehicle entering NCR area Developing a fog forecasting model for power system in NR Chemical Analysis of deposits on Insulator Strings and Pollution Mapping

of the Country Implementation of recommendations of high level committee on

Insulation requirement of EHV transmission lines including pollution mapping in the country.

Members may kindly note for implementation.

C.15 PROVISION OF BUS BAR PROTECTION SCHEME AT VARIOUS 220KV SUBSTATIONS OF PSEB

Bus bar protection is important and essential for enhancing the reliability of power system. This scheme has already been provided at all 400KV sub stations and important 220KV Substations of POWERGRID, DTL, UP, Rajasthan and Haryana power system and in the process of installation at other 220KV Substations, whereas Punjab is lagging very much in this regard. At present, PSEB have 48 nos of 220KV Grid substations and Generating Substations in operational conditions and except, at three nos of 220KV Generating substations (at Bhatinda, Ropar and Lehra Mohabbat), none of the Grid substations (45 nos) have been provided with Bus bar protection scheme.

As per the provision of Section-6, of CBIP Publication no. 274 (revised)

November 1999 and Clause-(1) at Part-III of CEA’s (Technical standard for connectivity to Grid) Regulation-2007, for existing substations at 400kV and at 220kV level having multiple feeds, bus bar protection is considered a must and the scheme is required to be implemented in reasonable time frame. In case of radial fed 220kV substations, having more than one bus, it is desirable to have bus bar protection but it is not a must.

POWERGRID, therefore in the1st Protection sub committee meeting

held on 5th September 2006 (on the issue of trippings at 220KV Malerkotla occurred on 4th June-2006), had pointed out that the scheme of bus bar protection at various substations of PSEB like Malerkotla, Moga, Verpal, Ablowal, etc, which are adjacent to their 400KV Substations, is essential to isolate the faulty elements of PSEB substations within a minimum possible time from POWERGRID substations. Since then, POWERGRID had taken up the matter with Member (Transmission), PSEB, and in a meeting held between them on 3rd August-2007 at Patiala, PSEB had formally agreed to provide bus bar protection on priority basis at 220KV Malerkotla substation by December-2007.

Matter had been followed up with Chairman, PSEB, and the status had

also been simultaneously updated through various meetings of Protection sub


committee of NRPC. But, PSEB, till 5th meeting of protection sub committee held on 28th March 2008, had not given a proper feedback on the implementation of bus bar protection scheme in PSEB system.

The issue was discussed in the 7th TCC and 8th NRPC meeting held at

Udaipur on 24th and 25th April 2008 respectively. As suggested by NRPC, Chairman, PSEB had agreed to expedite the matter and to inform the programme for implementation of the scheme within a month.

The issue was again discussed in the 8th TCC and 9th NRPC meeting

held on 30.6.2008 and 01.07.2008 respectively. PSEB informed that in the first instance the scheme would be provided at 5 Nos of 220 kV sub-stations. NRPC requested PSEB to expedite the implementation of scheme. PSEB assured to make all out effort to complete the work.

During the 10th NRPC meeting held on 30.09.2008, PSEB agreed to

increase bus bar protection from 5 to 12 nos Sub-stations from and they will complete the installation at 5 sub stations by March 09. Chairman NRPC advised PSEB to complete the remaining work latest by Dec 09.

PSEB may like to update the latest status. C.16 Implementation of Fibre Optic network in lieu of existing Microwave

(MW) network operating in 2.3-2.4 GHz frequency band

Microwave communication network comprising of 78 hops was implemented in NR-ULDC project in 2.3-2.5 GHz band. Department of Telecommunication (DoT) vide letter dated 14.07.2006 & 19.08.2008 advised POWERGRID to take necessary action for vacation of 2.3-2.4 GHz frequency band as this band is to be allotted to Broadband Wireless Access (BWA) services by DoT.

As desired by Constituents during the 10th NRPC meeting held on 30.09.2008, the issue of vacation of frequency band was taken up by POWERGRID with DoT through Ministry of Power. The matter was also taken up by Chairperson, NRPC with Secretary (Power), MoP.

The matter was discussed in a meeting held on 4.11.2008 under

chairmanship of Addl. Secretary, DoT, Ministry of communications & IT attended by Addl. Secretary, Ministry of Power in presence of CMD, POWERGRID.

As per the conclusion in the meeting: (i) 2.3-2.4 GHz frequency band in Microwave links under ULDC project is to be vacated within 2 years time. Further, the cost compensation sought from DoT for early replacement of Microwave links as suggested by Constituents has not been agreed by DoT. Accordingly, Fibre Optic based Wideband communication network is to be implemented in lieu of existing Microwave links within the time frame of 2 years.


Since, time schedule for vacation of frequencies has been decided at

Ministry level meeting. Constituents may give their consent to POWERGRID to go ahead for implementation of OPGW based communication network to replace Microwave links.

To replace all microwave links in Northern Region, about 3393 km of fibre optic cable is to be laid. Constituent wise break up of fibre optic cable and its tentative cost is as follows: Constituent Fibre Optic cable length

D.2 MEMBERSHIP IN NRPC AS PER AMENDED RESOLUTION BY MoP :

Northern Regional Power Committee (NRPC) has been constituted vide Government of India, Ministry of Power Resolution dated 25th May 2005 and Amendment Resolution dated 29th November 2005. Ministry of Power on 09.05.2008 had issued amendment to the earlier Resolution dated 25.05.2005 and 29.11.2005 on establishment of RPCs. A copy of the same is attached at Annex-XI. There has been change in representation from Electricity traders, Generating Company other than central generating companies or State Government owned generating companies and distribution companies.

With regard to representation from Electricity Traders it may be

mentioned that CERC have issued electricity trading license to 40 Nos of companies. The list is attached at Annex-XII. However, as per the Regional Energy Accounts prepared in NRPC Secretariat following Electricity Traders has been operating in the Northern Region during the 2008-09 (upto Nov.2008).

1. Adani Enterprises Ltd., 2. GMR Energy Trading Limited 3. Instinct advertisement & Marketing Limited, 4. JSW Power Trading Company Limited 5. Kalyani Power Development Private Limited, 6. Karam Chand Thapar & Bros. (Coal Sales) Limited, 7. Lanco Electric Utility Limited, 8. NTPC Vidyut Vyapar Nigam Ltd., 9. PTC India Limited 10. Reliance Energy Trading Ltd., 11. Tata Power Trading Company Ltd., 12. Vandana Global Limited 13. Vinergy International Private Limited,

These Electricity Traders will be requested to furnish the information on energy traded during the year 2008-09. The traders having trading volume of more than 500 MU in the year 2008-09 will be considered for membership in NRPC for the year 2009-10. M/S Adani Enterprises Ltd. is currently a member of NRPC since 2005-06 as a representative of Electricity Trader. It has been


seen that the representative of M/S Adani Export Ltd. has not been regularly attending the TCC/NRPC as well as sub-committee meetings of NRPC. They have also not deposited the contributions towards annual expenditure of NRPC secretariat for the year 2006-07 and the current year 2008-09. Thus, they will not be considered for membership for the next year (2009-10). NRPC may approve the approach so that Secretariat can move ahead for finalization of representative of Electricity Traders in NRPC for the year 2009-10.

D.3 UTILISATION OF REACTIVE ENERGY CHARGES:

NRLDC have informed that an amount of Rs. 37.90 crore is available in

Reactive pool for year 2002-06. NRLDC also informed that J&K had still to pay Rs. 26.364 crore of reactive energy charges for the period 2006-08 and about Rs. 9.482 crore for the current year till week – 31.

With regard to surplus available in Reactive pool as mentioned by

NRLDC, it is to be mentioned that, as per IEGC effective from 1st April, 2006, the money remaining in the regional reactive account upto 31st March of every year shall be utilized for training of the SLDC operators, and other similar purposes which would help in improving /streamlining the operation of the respective regional grids, as decided by the respective RPC from time to time.

It is seen that in Eastern Region the surplus available in Reactive pool

is being utilized for training purposes. On similar line it is proposed to utilize surplus amount in reactive pool of Northern Region for conducting training/work shops as per IEGC. At present there is no surplus available in the pool for the year 2006-07 onward as there is substantial outstanding amount against J&K as mentioned above. However, till the time J&K liquidate the outstanding Reactive Energy Charges for the year 2006-07 onward against J&K, some amount from the surplus available for the year 2002-06 could be utilized for the purpose of training/work shops as the amount required for this purpose is not much. Balance amount from total of Rs. 37.90 crore ( for 2002-06) after taking in to consideration the expenditure for training as above and already approved amount of Rs. 22 crore to J&K for installation of capacitors in their system and some amount around Rs 1 crore to HPSEB could be considered for installation of capacitors by others States.

The matter was discussed in the 10th Commercial sub-Committee

meeting held on 12.121.2008. Members supported the proposal of utilization of some surplus amount available in Reactive pool for the purpose of training/work shops as per IEGC. It was decided to constitute sub-group consisting of the following members to finalize the modalities of training/work shops.

SUPPLEMENTARY AGENDA-2

FOR 10th MEETING OF TECHNICAL COORDINATION SUB-COMMITTEE

& 11th MEETING OF NORTHERN REGIONAL POWER COMMITTEE

C.18 Evolving standard designs for multi-circuit and multi-conductor

line towers for 400 kV and 220 kV voltage level In the 26th Meeting of Standing Committee of Transmission System Planning, representative of RRVPNL suggested that the work of standardization of tower design was of utmost importance for the speedy execution of transmission projects. This was a very important work where CEA with its vast experience could assist the power utilities in Northern Region by taking up design and testing of tower and the expenditure involved could be shared by the constituent States of Northern Region. CEA has examined the proposal to take up the work relating to design and testing of transmission tower for 220 kV and 400 kV and a self contained proposal is given below: Towers for transmission lines are normally designed based on wind zone, terrain category, ambient conditions, Number of Circuits and Type / Number of conductors. Normally four types of towers [Type A(0-2deg.), B (2-15deg.), C(15-30deg.), D(30-60deg.)] are being commonly used excluding special towers(river crossing, railway crossing, power line/communication line crossing etc.). There are six wind zones in the country as per Indian Standards. In Northern Region most of the areas come under wind zone-IV and II although ambient condition varies widely from subzero degree temperature to about 50 deg.C. a small part of Northern Region falls under wind zone VI (Leh Area) which can be taken up later on if required. Therefore, towers have to be designed under following conditions.

• Wind Zone IV, Every Day Temperature(EDT): 32 deg.C under Non- snow conditions.

• Wind Zone II, Every Day Temperature(EDT): 32deg.C under Non- snow conditions.

• Wind Zone II, Every Day Temperature(EDT): 15 Deg.C and Min. temperature: -15deg.C under Snow zone conditions.

As the first instance, towers in the major area of Northern region falling in the wind zone IV, may be taken. Towers with twin conductors/quad conductors/multi-circuit, are required to be designed.

The following criteria and parameters for which towers have to be designed can be considered:

Wind Zone

400 kV(D/C)

To start with the standardization work, 12 Nos. of towers at voltage levels of 220 kV/400 kV, in wind zone 4 could be taken up for design and remaining towers in wind zone 2 in snow and non-snow area may be taken up later on. To accomplish such a challenging task, time lines for various activities need to be defined and at the same time it requires a lot of infrastructure and support. With the available infrastructure both manpower & resources in CEA, it would be difficult for SE&TD division of CEA alone to carry out such voluminous work within a short time frame. The following action plan is suggested:

• Formation of a separate core group within CEA which would be exclusively involved in such works. The core group can be headed by CE(SETD /SP&PA) who is to be assisted by at least 1 Superintending Engineer, 2 Executive Engineers, 2 Asstt. Engineers and supporting staff. In addition to manpower, computer facility and specialize tower design software with multi-user facility would need to be provided. Due to shortage of required number of persons in SE&TD division of CEA, additional persons including supporting staff can be engaged, if feasible from different Divisions of CEA, and from other Power Utilities. Officers engaged from CEA /Power Utilities should be willing to work on design of transmission line towers with software assistance. Northern Region constituents would need to identify engineers to have aptitude to design work, to be deputed to CEA to work along with the team for development of the standard tower designs. This would help in building up a core transmission tower design group in the utilities.

The Constituents of the NRPC may like to consider the above proposal of taking up standard tower designs for the benefit of the constituents at an estimated cost of Rs. 920 lakhs [for 4types of 220kV Quad Ckt towers + 4 Nos. of 400kV D/c towers with twin conductors + 4 Nos. of 400kV D/c towers with Quad conductors in wind Zone-IV] and depute all engineers to assist the core group in CEA for carrying out the above assignment. The above expenditure may be met from contribution from the constituent states and routed through the present funding arrangement of NRPC. The phasing of expenditure would be intimated after detailed proposals are framed.

• The core group shall formulate the design parameters in association

with power utilities, meeting varied requirements of different power utilities. The work of design of towers including civil foundation design, preparation of Structural assembly Drawings / Fabrication drawings and testing of towers prototype shall be outsourced. The work can be outsourced to different agencies who are involved in such type of fabrication and testing works e.g KEC, Joyti, ASTL, L&T, Kalpatru, SERC, CPRI etc. The work can be directly awarded to Govt. agencies like CPRI or SERC, if they, agree to do such type of work. In case their service can not be utilized, work can be awarded to private players on the basis of competitive bidding. The cost associated with design, development of structural drawings, proto assembly and testing charges in respect of the various types of towers as collected from CPRI/other private agencies works out to Rs.920 lakhs.[for 12 types of towers in wind zone -IV] and Rs.1840 lakhs. [for additional 24 types of towers in Wind zone -II] totaling Rs. 2760 lakhs. The core group shall be involved in preparing all the designs, examining the structural drawings and inspection of proto assembly and testing of towers.

Members may like to deliberate and concur.
