Subject : Summary Record of discussions held in the 11th Meeting of the Grid Coordination Committee (GCC) of Delhi, held on 29.12.2014 at 10:30Hrs. at Conference Hall, NRPC Secretariat, Katwaria Sarai, New Delhi-110016

The list of participants is enclosed at Annexure.

WELCOME

Sh. A.K. Haldar, Director (Operations), DTL, Chairman GCC could not attend the meeting due to his indisposition. According to the conduct of business rules of GCC, Sh. Jagdish Kumar, Director (Technical), IPGCL/PPCL chaired the meeting with the consent of the house.

Sh. Jagdish welcomed all participants to the 11th GCC meeting on behalf of IPGCL /PPCL. He also expressed thanks to GCC for giving an opportunity to IPGCL / PPCL hold this meeting.

He stated that earlier this meeting was scheduled on 29th October, 2014; however, due to declaration of holiday, it was postponed to a later date. Since last GCC meeting there were lot many issues related to Grid Operation of Delhi state which need to be discussed and consensus decisions are to be taken in the larger interest of Grid operation of Delhi state to ensure 24 x 7 power supply to the consumers of National capital of Delhi. Talking about the demand and supply of power in Delhi state, it was noted that power demand touched a new high of 6006MW in July 2014 out of which demand met was 5925 MW. During the month August 2014, demand increased by 14.8%. The power supply position has by and large been satisfactory up to 30.05.2014. However, due to devastating storm occurred in the afternoon hours of 30.05.2014, the power supply got disturbed due to tripping of large number of transmission lines in Delhi along with other states in NR and CTU System. However, with the concrete help of Central Power Transmission Utility, PGCIL, the power system could be normalized by the 2nd fortnight of June 2014.

CEA has also conducted enquiry of the tower collapses and submitted its report. The Expert Committee has made recommendations to avoid the recurrence the failures. There are other issues of Grid operation like compensation for transformation losses between DISCOMS in inter DISCOM transfer, O&M charges regarding installation & maintenance of numerical relays, adjustment of short term open access charges in monthly wheeling charges bills of DTL, payment of NRLDC charges, revision of wheeling charges invoices for the period April 2014 to July 2014., waiver of DSM penalty on account of transmission

line tripping, minimum technical limit of coal based generation which are part of agenda of this GCC meeting. These agenda will be taken up one by one for deliberations and decisions, however, on behalf of generating companies he pointed out one of the major issues related to partial scheduling of power from the stations. The continuous partial load scheduling resulting into reduced / part load operation of units. He pointed out that the continuous part load operation and frequent stop-start results in reduced life of the equipments and increased heat rate and auxiliary power and as a result the reliability and efficiency of the power stations severely affected. The increased heat rate and auxiliary power consumption is not compensated to generators beyond normative values as specified by the Regulatory Commissions to individual stations. Therefore, he requested SLDC to take care these aspects while scheduling for part load operation of the plants and requested further that it should not rely only on economics of power generation with available figures of ECR (Energy Charge Rates) but also consider the impact of part load operation on reliability of machines, financial impact on generators also.

One of the crucial issues of Delhi state is the issue of cash crisis owing to the irregular payments by some Discoms. Bills are piling up without realization from DISCOMS like BRPL & BYPL on account of transmission and generation tariff of DTL and IPGCL & PPCL. Even the Hon’ble Supreme Court’s orders for payment of current dues are not being complied with. The cash flow problem in the system has resulted in deferment of scheduled and preventive maintenance of the plant & equipments of IPGCL & PPCL. This may result in non-availability of embedded and reliable power with options of emergency availability to VVIP areas and strategic important installations. He requested all the utilities to pay generating and transmission utilities at least the current payment as directed by Supreme Court to avert collapse of the system.

Further, unilateral and ad hoc decisions of Grid operators in some cases need to be addressed and resolved in larger interest of Grid operation. One of them is issuing of ad hoc energy account of RPH. The overhauling of RPH has been delayed due to delay in supply of spares for overhauling by BHEL. IPGCL has been pursuing with BHEL for the same. As of now, RPH units remain available till its units are taken for overhauling one by one, which is expected to get completed before 31.03.2015. The issue of availability of RPH is one of the agenda on behalf of IPGCL and he hoped that this GCC meeting will deliberate this issue and would arrive a consensus decision regarding availability of RPH as per the provisions of State Grid Code.

He once again welcomed all the participants of the GCC on behalf of IPGCL & PPCL and hoped that during the deliberations the lot many issues which are pending will get resolved.

After the welcome address of the Chairperson, the agenda was put up for discussions and the gist of the discussions and decisions are as under:-

1 CONFIRMATION OF THE MINUTES OF 10TH MEETING OF GCC HELD ON 29.01.2014.

The minutes of the 10th meeting of GCC held on 29.01.2014 have been circulated vide letter no. F.DTL/207/13-14/DGM(SO)/214 dated 12.03.2014. No comments have been received so far.

GCC confirmed the minutes of the 10th meeting of GCC held on 29.01.14. 7

2 FOLLOWUP ACTION ON THE DECISIONS TAKEN IN THE PREVIOUS GCC MEETINGS

2.1. PROVSIONS OF HOT RESERVE OF TRANSFORMERS.

The latest position on the issue was informed as under:-

S.N Capacity Present Original planning Present Status popula for hot reserve tion in nos. 1 400/220 16 One Tx at 400kV At present, there are two 400/220kV 315MVA kV, Mundka would be Transformers at Mundka. With the 315MVA hot reserve. commissioning of 220kV Peera Garhi and ICT Wazirpur double circuit lines and LILO of 220kV Najafgarh – Kanjhawala Ckt at Mundka, the load would be increased and hence the spare capacity is required as hot reserve. The case for provision of one transformer as Hot reserve at Mundka was put up to DERC but considering the present load, it was advised to defer the provision of Hot reserve. However, it has now been proposed that after the proposed augmentation of two 315MVA Txs at Bamnauli to 500MVA being done by PGCIL on behalf of DTL, the provision for hot reserve for one transformer available at Bamnauli would be done at Mundka The other 315MVA Tx which would be free after augmentation at Bamnauli would also be placed at Bamnauli. 2 220/66 kV, 16 160MVA Tx Since the load of Pappankalan-II has alrady been 160MVA earmerked for attained near to the full capacity, the 220/66kV Tx 220kV Pappan 160MVA Tx is no more the hot reserve. The Kalan-II would be scheme for installation of another 220/66kV the hot reserve. 160MVA Tx as hot reserve has been proposed to be installed by June 2015. 3 220/66kV, 41 New Tx. is required The transformer meant as hot reserve available at 100MVA to be purchased The Patparganj has been diverted to replaced the Tx scheme for one damaged 220/66kV 100MVA Tx-I at Park Street. 4 220/33kV, 35 220/66/ 33kV Procurement of new transformer is in progrress 100MVA 100MVA Tx as hot and expected by December 2015. Tx, reserve has been Further, DERC has advised DTL to explore the approved and the possibility of keeping cold reserve as oil filled same would be transformers are not easy to transport. In this placed at Patparganj regard, Power Grid was also consulted for the before summer policy in their system. It was reveleaed that there 2014 for hot reserve are no such policy to keep the reserve transformer in hot condition or cold condition but both system exists there. Considering the opertional criteria i.e. to ensure healthy hot reserve, GCC advised DTL to go ahead for hot reserve. 5 66/11kV 24 The scheme for a DERC has already decided that DTL should not 20MVA 66/11kV Tx as a invest in building up assets to feed 11kV load Tx hot reserve has from 220kV S/Stns. been approved and transformer is under procurement.

2.2 IMPLEMENTATION OF AUTOMATIC STATE-OF-THE–ART–LOAD MANAGEMENT SCHEME BY DISCOMS

CERC vide order dated 28.12.2013 issued notices to all State Utilities except Delhi for non implementation of The State-Of-The-Art Load Management Scheme (as Delhi has implemented the scheme). As directed by CERC, all RLDCs have filed the status report of the implementation of the scheme before CERC. Final order in this regard (non implementation of demand management scheme) is expected shortly.

All utilities of Delhi need to maintain the system and ensure that the scheme is operation at all point of time. It is also brought in the notice that of amendment of Indian Electricity Grid Code has been made applicable from 17.02.2014. The relevant portions of the amended IEGC is appended hereunder :-

5.4.2 Demand Disconnection

(a) SLDC/SEB/distribution licensee and bulk consumer shall initiate action to restrict the drawal of its control area,from the grid, within the net drawal schedule.

(b) The SLDC/SEB/distribution licensee and bulk consumer shall ensure that requisite load shedding is carried out in its control area so that there is no overdrawl.

d) The SLDC through respective State Electricity Boards/ Distribution Licensees shall also formulate and implement state-of-the-art demand management schemes for automatic demand management like rotational load shedding, demand response (which may include lower tariff for interruptible loads) etc. before 01.01.2011, to reduce overdrawl in order to comply para 5.4.2 (a) and (b) . A Report detailing the scheme and periodic reports on progress of implementation of the schemes shall be sent to the Central Commission by the concerned SLDC.

The amended regulation of 6.4.7 of IEGC is also appended hereunder:-

"7. The SLDC, SEB / distribution licensee shall always restrict the net drawal of the state from the grid within the drawal schedules keeping the deviations from the schedule within the limits specified in the Deviation Settlement Mechanism Regulations. The concerned SEB/distribution licensee/User, SLDC shall ensure that their automatic demand management scheme mentioned in clause 5.4.2 acts to ensure that there is no over-drawal. If the automatic demand management scheme has not yet been commissioned, then action shall be taken as per manual demand management scheme to restrict the net drawal from grid to within schedules and all actions for early commissioning of Automatic Demand Management Scheme (ADMS) shall be initiated

All Discoms are to ensure the working of Automatic Demand – Management Scheme (ADMS) in line with the above provisions of Grid Code.

All Distribution Utilities informed that the present ADMS is based on frequency based load shedding as per provisions of earlier Grid Codes. To ensure the compliance of new provisions, the frequency parameters are required to be excluded to ensure scheduled drawal all times. Accordingly the vendors are required to change the necessary provisions in the existing SCADA system which is the lengthy process as the present SCADA Systems were implemented long back and changes in softwares normally takes long time as per experience. Further, it was also apprehended that load shedding would be a continuous phenomenon in distribution areas even when the drawal of the state as a whole is less than the scheduled drawal. The telemetry system apart from real time scheduling should also be ensured 100% accuracy to avoid unwanted load shedding thereby inconvenience to the general public.

After discussions, it was decided that Discoms should keep their drawal as per their drawal schedule and at the same time should also consider the drawal of Delhi as a whole from the Grid so as to avoid unnecessary load shedding in case Delhi’s drawal is less than the scheduled drawal. It was also advised that all Discoms should enable the existing ADMS system based on the revised Grid Codes as early as possible.

2.3 OUTSTANDING DUES

Generating utilities namely IPGCL, PPCL and Transmission utility DTL informed GCC that BRPL and BYPL are not paying the dues as per the claim despite the order of Hon’ble Supreme Court to pay the dues from January 2014 onwards for the power supplied / power transmitted. DTL informed that BRPL and BYPL are not paying any amount from October 2014 onwards. They have quoted the relevant Supreme Court order in this regard as under:-

ORDER Dated 06.05.2014

Heard learned counsel for the parties at length.

With regard to the adjustment of subsidy and UI diversion, the Appellate Tribunal of Electricity vide its order dated 23.05.2014 has categorically stated that the amount should be adjusted against the outstanding dues as per the orders of the Govt. of NCT of Delhi. The excerpts of the order of the Tribunal in this regard are appended hereunder:- 12. In view of above, the amount of Govt. subsidy and UI amounts credited to the Applicants have been correctly adjusted only against the outstanding dues but not against the current dues from January to March 2014 as per the directions of the Govt of NCT.

13. Therefore, we direct the Respondent Discoms to make payment to the Applicants/Appellants for the current payments from the billing period from 1.1.2014 regularly as per the directions of the Hon’ble Supreme Court.

However, BSES utilities challenged the order of the Tribunal in the Supreme Court and notices were issued to DERC, DTL and Delhi Gencos.

The above figures are without considering the amount received during March 2014 as subsidy to the tune of Rs. 72 Crores in respect of BRPL and BYPL together. The amount is without LPSC.

They also informed that even day to day operations are affected due to cash crunch and requested the defaulting utilities to pay the dues. The representative further feared that in case of non payment the continuity of supply may also get affected as these utilities are not paying any amount from October 2014 onwards.

BRPL placed the following facts before the Committee:- i) BRPL is facing precarious financial condition due to non-cost reflective tariff and accumulation of Regulatory Asset since FY 2008-09. On account of the same amongst other reasons BRPL was unable to pay outstanding dues of the Central and State utilities. Accordingly, BRPL had filed Writ Petition No. 104 of 2014 before the Hon’ble Supreme Court of India wherein State Gencos and Transcos are also parties. ii) The Hon’ble Supreme Court by its order dated 26.03.2014 had directed BRPL to pay the current payments to the generating and transmission companies with effect from 01.03.2014 which will relate to the billing period from 01.01.2014. iii) Despite tariff being non- cost reflective and absence of a credible amortization schedule for liquidation of Regulatory Asset, BRPL has paid current dues up to October 2014 to the State Gencos and Transco in terms of the Hon’ble Supreme Court’s order dated 26.03.2014. BRPL was able to discharge the dues till October 2014, by resorting to extensive borrowings from banks and financial institutions. iv) Although Delhi Commission has submitted a Road-map for liquidation of Regulatory Assets, the issue is still pending before Hon’ble Supreme Court. Consequently, in the absence of any clear road-map to liquidate the Regulatory Assets the banks and financial institutions are unwilling to extend further loans. v) The cost of power of the Delhi Gencos including other stations has also increased substantially during FY 2014-15. In this regard BRPL raised its concern as contained in letters dated 08.08.14 and 27.08.14 to the State Gencos. The cost of gas based stations of Delhi alone has registered an increase of 61% in energy charges during the period April 2014 to July 2014. Further, it has shown a substantial increase than the expected rate of ECR based which on schedules have been done. The details of energy charges in comparison with that previous years of Delhi Gencos are as under:-

Energy Charges in Ps/Unit for gas stations on CCNG Month GT Station Pragati Stage-I Bawana BTPS 2013 2014 2013 2014 2013 2014 2013 2014 April 392 389 246 337 270 293 361 444 May. 373 419 304 226 270 284 339 459 June 396 520 287 304 272 313 328 473 July 346 627 324 520 285 288 331 474 August 303 420 291 458 290 317 323 463 September 402 466 669 442 304 308 347 463 October 306 351 477 461 305 293 382 446 November 278 358 322 385 297 309 433 443 December 308 372 376 425 302 313 472 452 Average 345 436 366 395 288 302 368 457 %age increase 26.38 7.92 4.86 24.18 w.r.t. previous year Note : The scheduling of May is done based on the energy charges of April and so on. vi) In order to restrict accumulation of further Regulatory Asset, Delhi Discoms had proposed a PPAC formula, to meet the variation in power purchase cost approved by Delhi Commission. Delhi Commission has revised the PPAC formula in its latest tariff order dated 23rd July 2014. Although BRPL had sought for PPAC of 7.26%, for quarter-2 (i.e. July-2014 to September-2014), however, Delhi Commission had approved a PPAC of only 4.5% on 13th November 2014, which was also withdrawn immediately on 14th November 2014. vii) Apart from the admitted fact that tariff is non-cost reflective, Delhi Commission by its Order dated 27.02.2014 has re-assigned the PPAs in the state of Delhi, whereby Delhi Commission has allocated costly power from BYPL to BRPL and cheaper power from BRPL to BYPL in order to take care of lower Average Billing Rate (ABR) of BYPL as under:

Earlier BRPL Revised BRPL Sl. Station Allocation Allocation Remarks No. (MU) (MU) 1 Dadri-I 1910.91 2508.37 55% of BYPL allocation shifted 2 Aravali 314.61 414.68 to BRPL 3 Singrauli 480.07 216.03 55% of BRPL allocation shifted 4 Sasan 790.56 355.75 to BYPL

This has further worsened the financial condition of BRPL. viii) The Writ Petition No. 104 of 2014 filed by BRPL is listed for final hearing on 14.01.2015. Once the issue is decided by Hon’ble Supreme Court there will be clarity on the issues which will help BRPL to arrange for funds from Banks and Financial Institutions. Thereafter, BRPL will be able to submit a credible plan to liquidate outstanding dues of the State Gencos and Transco. Till such time, the Hon’ble Supreme Court decides the Application and Writ Petition cooperation from all stakeholders including IPGCL/PPCL/DTL/Delhi Govt for accommodation in the current adverse financial situation is sought.

BYPL’s submissions were also similar to BRPL and informed that due to the cash crunch, they could not be able to make the payment and all out efforts are on to make the payments. This was indicated by the CEO’s of the respective company when the representatives of DTL met them.

SLDC representative brought out the legal proceedings initiated by DVC in Hon’ble Supreme Court due to non payment of dues despite the order of the Court dated 20.10.2011 in Writ petition (Civil) no. 328/1999 in the Matter of Power Crisis in Delhi as detailed hereunder:-

O R D E R dated 20.10.2011

We clarify that the aforesaid direction is purely an ad hoc arrangement in order to see that the Corporation receives some amount against outstanding dues, intimated to the said distribution companies vide demand notices. In addition to the above, the said two distribution companies shall continue to pay the current charges, in terms of the contracts, for supply of energy by the Corporation, on the basis of the bills as may be raised by them, by the due date. However, it will be open to the parties to have negotiated settlement if there is any dispute in relation to the rate at which the energy is to be supplied by the Corporation. List the application for further directions on 8th December, 2011 at 2.00 p.m. Personal appearance of the Chief Financial Officers of both the afore-stated companies is dispensed with.

To the query of any legal proceedings in line with DVC, DTL informed that they would intimate the matter of non payment of dues during the next hearing. It was also informed that with regard to separate legal proceedings of non payment of dues despite the order of Hon’ble Supreme Court for the payment of dues from January 2014, it was informed that DTL has already moved the case and sought approval from State Govt to initiate the legal proceedings.

GCC requested the utilities to pay the dues as per the Hon’ble Supreme Court directions to maintain the day to day operations of the Generating and Transmission Utilities thereby the consumers’ supply can be maintained.

It was also informed that 48 lines of PGCIL also tripped during the storm on 30.05.2014. It is also reported that the towers of one 400kV Double Ckt. & tower of three 400kV single circuit and towers of two 765kV circuits collapsed. The Central Commission vide its order dt 20.06.2014 has directed CTU to investigate the reason for tower collapses and other related issues

CEA has also conducted enquiry of the tower collapses and submitted its report. As far as Delhi system is concerned, CEA has concluded that the tower collapse is not due to maintenance issues but because of turbulent weather conditions. The following recommendations have also been made by the Expert Committee to avoid the recurrence the such failures.

Recommendations/ Remedial measures to be taken by Delhi Transco Ltd. as indicated by the Expert Committee.

(i) Towers of the line were designed as per old code IS:802 (1977) and the wind zone for Delhi area has been changed as per revised code IS: 802 (1995). In view of the above, DTL may review design of towers in line with latest IS codes and strengthening of members of tower, if required, may be carried out accordingly to avoid reoccurrence of such failures in future and thereby increase the availability of the line. PGCIL/CPRI/SERC / any other organization may be consulted for review of the design.

(ii) In future, the use of tower designed as per old IS:802(1977), should be avoided as a replacement to failed towers in any existing lines or in new lines until the design review is complete.

(iii) The regular patrolling of lines should be carried out by DTL to check for missing of tower members. Regular maintenance activities such as chopping of nearby trees to maintain adequate safety clearances, considering MOE & F guidelines, removing the bushes near the foundation area, and coping of chimneys etc. should be carried out by DTL from time to time, as and when required.

(iv) For old lines, rusting in members of all the towers (due to exposure to atmosphere over a long period of time) may be checked and painting of the rusted members with Zinc rich paints may be done as remedial measures.

(v) The holes in the tower members including leg members are to be filled with bolts & nuts to increase the strength of members.

(vi) Chimneys of all the towers should be provided with coping to avoid accumulation of rain water near stub. If required, the height of the chimneys may be raised where the tower is located in agricultural field to avoid deposit of soil on the chimneys due to agricultural activities.

(vii) Quality of steel material may be ensured while replacing these missing members.

(viii) Material test of the failed tower members should be carried out from recognized NABL approved laboratories / Govt. approved laboratories to assess the quality of steel material used in the tower.

CERC has also sought certain information from CEA as far as PGCIL on the matter of collapse of towers. The details of RoP dated 14.10.2014 is appended hereunder:-

Record of Proceedings in Petition No. 9/SM/2014 (Date of Hearing 14.10.2014)

The representative of Power Grid Corporation of India Limited (PGCIL) submitted that on 30.5.2014 towers had collapsed due to high intensity of wind and these towers were designed for Wind Zone 4 which corresponds to 169 kms/hrs wind speed. He further submitted that the tower design was done according to IS standards with reliability period of 50 years.

2. In response to the Commission`s query as to whether PGCIL keeps data of last 50 years, the representative of PGCIL submitted that PGCIL consider IMD data and IMD has divided the country into various wind zones. He further submitted that PGCIL designs transmission lines and towers based on the appropriate wind zone.

3. The representative of Central Electricity Authority (CEA) submitted that prior to 1997, transmission towers were designed considering three wind zones. However, in 1997, country was demarcated into six wind zones and now towers are accordingly designed considering a reliability factor of '2' for 765 kV and '1' for 400 kV lines. The representative of CEA further submitted that the tower damage in 765 kV Fatehpur line was also discussed in Standing Committee meeting held on 19.6.2014 and report in this regard has already been submitted today before the Commission.

4. The representative of POSOCO submitted that copy of report submitted by PGCIL is not available with POSOCO. He further submitted that as per National Electricity Plan 2007, N-2 criteria needs to be adopted for large generating stations (3000 MW) and multi line corridors (3 D/C lines or more). However, it has not been achieved so far. The representative of POSOCO submitted that there is a need to consider this aspect while planning the transmission system.

5. After hearing the representatives of the respondents, the Commission observed that 15 towers collapsed on 765 kV Gaya- Fatehpur line on 31.5.2014 and directed CEA to investigate the issue in detail and submit a report by 30.11.2014.

6. The Commission directed PGCIL to serve copy of the report to POSOCO.

7. The Commission directed PGCIL to investigate in coordination with CEA in detail failure of towers on 30.5.2014 and 31.5.2014 considering the structural, and workmanship aspects, material used and O&M practices involving academia and submit a report within three months of the issue of the ROP and suggest remedial measures.

8. The Commission directed POSOCO to investigate the incident of SSR, delayed generators response and delayed clearance of faults on the transmission system in consultation with CEA and submit a report within two months of the issue of the ROP. 9. Subject to above, the Commission reserved order in the petition.

DERC has also initiated suo-moto proceedings to look into the issues of load shedding on 30.05.2014 and 06.06.2014 vide its order dated 03.12.2014 directed the following :-

1. Mr. Alok Shankar, Ld. Counsel for TPDDL made a request for grant of some time to file a reply to DTL’s submission filed on 17.11.2014. The Commission considered the request and granted two weeks time to file a reply with an advance copy to DTL.

2. Mr. Rajeev Mehra, Sr. Adv for BRPL/BYPL submitted that the Central Electricity Regulatory Commission vide Petition no. 9/SM/2014 is also taking suo-motu action on the load crash in Northern Region on 30.05.2014 wherein DTL is a party.

3. Ld. Counsel further submitted that the CERC directed PGCIL to investigate with CEA in detail failure of towers on 30.05.2014 and 31.05.2014 considering the structural, and workmanship aspects, material used and O&M practices involving academia and submit a report within three months and suggest remedial measures. Further, the Central Commission directed POSOCO to investigate the incident of SSR, delayed generators response and delayed clearance of faults on the transmission system in consultation with CEA and submit a report within two months.

4. In view of the above the Commission directed Mr. Mehra to apprise the Commission about final order of the CERC and thereafter matter may be listed for further hearing.

5. Ordered Accordingly.

General Manager (O&M)-I, DTL informed that the detailed study of 1700 towers on 20 parameters has been carried out. All the deficiencies would be cleared in a planned manner. Necessary tower design change would also be carried out to avoid the recurrence of such collapses in future. He further added that 56 numbers of damaged / rusted tower legs / stubs of 220kV Mandola – Gopalpur D/C line, 220kV Mandola – Narela D/C line and 220kV Bawana – Rohini D/C line have been

reinforced. Additional tower earthing on 110 towers out of identified 137 towers have been completed and remaining shall be completed by end of January 2015. The other strengthening work of identified towers shall be taken on priority to make it completed before 31.05.2015. ii) Shut-down of Pragati Stage-1 units.

Even though substantial backing down occurred during the period October 2013 to March 2014, shut-down of units was not taken due to one reason or other. The shut-downs were finally taken from April 2014 but went beyond mid June 2014 causing reduction in crucial generation of about 150-200 MW at load centre resulting into load shedding in east, central and south Delhi areas. The details of shut-downs planned and availed by Pragati Stage-I units are as under:-

Unit Original Revised Actual Reason of shut- Reduction in Shutdown as schedule shutdown down Generation per LGBR availed (MW) 1 01.04.14- 16.04.14- 27.04.14- Major inspection 150 30.04.14 15.05.14 18.06.14 / overhauling 2 Feb 14 - Mar 08.04.14- 08.04.14- Combustion 150 14 (10days) 16.04.14 27.04.14 inspection STG 01.04.14- 14.04.14- 16.04.14- Bearing 110 15.04.14 30.04.14 19.05.14 inspection / (200MW from exciter 27.04.14 to overhauling 19.05.14) iii) Unstable operation of RPH Station

The RPH units could not deliver stable generation during the summer. It also resulted into over-loading of transmission lines between 220kV Wazirabad – Geeta Colony section causing load shedding in East Delhi and Walled city areas. The details of availability of RPH for summer season have been as under:-

Month Plant availability in %age Scheduled PLF in %age April 2014 82.09 37.04 May 2014 72.13 62.98 June 2014 76.39 74.70 July 2014 57.79 57.79 August 2004 55.00 46.47 Sept 2014 51.94 51.94 April to Sep 2014 65.82 55.13 iv) Less generation at Badarpur Thermal Power Station

Even though, the Badarpur generation is one of the costliest sources of thermal generation in the country, the scheduling is done to meet the transmission system constraints in and around the areas. The details of the plant availability during the summer months has been as under:-

Month Plant availability in %age Scheduled PLF in %age April 2014 78.72 51.70 May 2014 89.12 68.67 June 2014 89.12 83.57 July 2014 87.49 76.65 August 2004 69.87 54.87 Sept 2014 52.96 46.82 Apr to Sep.2014 77.96 63.66 v) Outage of 220kV BTPS – Noida – Gazipur Ckt. (UPPTCL Ckt)

During the crucial crisis period, the 220kV BTPS – Noida – Gazipur ckt which was giving support of about 160MW remained out (during the period 01.05.2014 to 20.05.2014, 07.06.2014 to 20.06.2014) causing huge load shedding in East Delhi areas.

The ckt is still out due to cable fault from 17.09.2014. UPPCL have started the repair work as the cable portion is required to be attended and is likely to be attended by 31.03.2015. g) Behaviour of transmission system at the time of occurrence of peak demand i.e. 5925MW at 15.20.20hrs. on 15.07.2014 was presented as under:-

5 Dadri (Th)-II Unit No. 2 (490MW capacity) is planned for maintenance during 01.02.2015 to 15.03.2015. 6 Dadri (Th)-I Unit No. 2 (210MW capacity) is planned for maintenance during 05.11.2014 to 19.12.2014. 7 Both units of RPH would be under outage due to Environmental stipulations. 8 285MW capacity of BTPS has been reallocated to Madhya Pradesh from 18.00hrs. of 01.10.2014 to 31.03.2015 by Govt. of India. However, on the request MP Govt, the allocation was returned back to Delhi w.e.f. 26.12.14. 9 Unit-5 (210MW) of BTPS will remain under shut-down during March 2015.

The above position indicates the substantial quantum of surplus power available which is normal phenomenon every winter i.e. November to March. To combat the issue, DPPG has taken various measures to dispose off the surplus power. i) On the recommendations of DPPG, Delhi Govt requested Central Govt. to reallocate 285MW capacity (3X95MW) of BTPS to needy states from October 2014 to March 2015. The capacity has been diverted to Madhya Pradesh from 18.00hrs. on 01.10.2014. However, the same has been returned back to Delhi from 26.12.2014. ii) The Central Govt has already reallocated the entire allocation of Aravali Jhajjar (693MW share of Delhi) to Kerala, Andhra Pradesh and Telangana upto 31.03.2015. iii) On the recommendations of DPPG, 180MW capacity of Delhi (TPDDL’s share in Dadri Thermal Stage-1) has been reallocated to Bihar from 10.09.2014 utpo 31.08.2015 from Dadri Thermal Stage-1. iv) DPPG has also recommended the temporarily reallocation of surplus power to needy states as detailed hereunder:-

Later, in the meeting November on 16.10.2014 in the office of 2014 to March Addl. Secretary (Power), 1500 157 157 2015 GNCTD, the proposal is dropped due to ongoing reduction in availability due to coal shortages. v) Closure of RPH units on account of Environmental Stipulations

To bring down the emission level below normal limits and as decided in the meeting chaired by Chief Secretary, Govt of Delhi held on 18.03.2014, the units have been closed down on 01.10.2014. The decision of the meeting is appended hereunder:-

1 To meet the pollution norms of 150mg/Nm3 Rajghat Power Station has to carry out major overhauling of both of the units one by one as the plant is running at deteriorated operational parameters. There is not shortcut method to bring down the SPM level upto desired value as the performance of EPIC Controller can only be achieved with the healthy condition of the ESP, Boiler and milling system. Overhauling along with installation of EPIC Controller will be carried out by RPH in September – October 2014 & March – April 2015 for Unit-2 & 1 respectively.

2 Till the remedial measures are taken the plant should run only during Peak load Hours to meet the demand of walled city area

3 Separate transmission line should be laid down within two years to overcome transmission constraints because presently there is only single transmission line for the walled city areas.

4 To expedite the proposal to convert the coal based power plant of (135MW) to Gas based plant (350MW).

DPPG in its meeting held on 28.09.2014 has also decided to close unit-2 at RPH to reduce emission level from 01.10.2014 (the other unit was out since 26.09.2014).

At the time of closing of the plant only one unit of RPH i.e. unit-2 was running on partial load i.e. about 40MW against the capacity of 67.5MW. The other unit was out since 10.17hrs. of 26.09.2014 due to flame failure. Since the closure, the plant is claiming 79% availability.

IPGCL representative strongly objected the certification of availability i.e. 50% of the declared capacity for the month of October 2014 and November 2014. According to them, the unilateral decision of SLDC to reduce the availability against the declared capacity of the station on daily basis (which is being displayed in the website of SLDC) is not accepted. The declared capacity of RPH for October 2014 is 79.26% and for November 2014, it is 79.23% whereas in the State Energy Accounts issued by Delhi SLDC indicated the availability for October 2014 as 39.63% and for November 2014 as 39.66%. They quoted clause 31.1(d), 31.3 and 32.1 of the Delhi Grid Code and relevant applicable clauses of Indian Electricity Grid Code Regulations and argued that the certification done by SLDC from October 2014 was not based on these provisions. The relevant clauses of Delhi Grid Code quoted are appended hereunder:-

31. Scheduling and Despatch Procedures 31.1 The SLDC shall develop, document and maintain detailed procedure in consultation with the in-State Generating Stations and the Distribution Licensees incorporating processes and operating instructions for Scheduling and Despatch under the IntraState ABT regime keeping in view the relevant orders of the Commission. These procedures shall include, but not limited to, the following:- a) ...... d) Exchange of Information for Scheduling and Rescheduling including scheduling of Inter-Distribution Licensee Transfer of Power, if any; 31.3 Despatch instructions shall be in standard format. These instructions will recognise declared availability and other parameters, which have been made available by the Generators to SLDC. These instructions shall include time, Power Station, Generating Units, name of operators sending and receiving the same. Despatch instructions may, in addition to approved generation schedule, include: (i) To switch a generator into or out of service. (ii) Details of Spinning Reserve to be maintained. (iii) To increase or decrease MVAr generation for maintaining the voltage profile. (iv) To begin pre-planned Black Start procedures. (v) To hold Generating Units on standby.

32 Time Table for Scheduling 32.1 Subject to Regulation 31, the exchange of information in respect of the Scheduling process shall be, in general, as per the following time table: Process for Scheduling (for succeeding day) By 09:00 Hrs— Inter-State Generating Stations (ISGSs) advise NRLDC the station wise MW and MWh capabilities as per IEGC provisions. By 09:00 Hrs — BTPS, IPGCL and PPCL (GENCOs) shall declare their availability to the SLDC in 15 minutes time block in terms of MW and MWh. By 10:00 Hrs — Entitlement of the state posted by NRLDC in its website www.nrldc.org for central sector. By 11:00 Hrs — SLDC shall post the IPGCL, PPCL and BTPS (GENCOs) availability in its website www.delhisldc.org By 13:00 Hrs — NDPL,BRPL,BYPL,NDMC and MES (DISCOMs) shall intimate the SLDC, source-wise requirement of power for succeeding day in terms in MW and MWh in 15 minutes time block. By 15:00 Hrs — SLDC shall assess the requirement of power from all sources and intimate the same to NRLDC. By 17:00 Hrs — NRLDC conveys the net drawal schedule for Delhi and posted in the website. By 18:00 Hrs — SLDC shall post the provisional Drawal Schedule of DISCOMs and Generation Schedule of GENCOs based on the provisional Drawal schedule of Delhi as a whole posted on the NRLDC website. By 19:00 Hrs — GENCOs/ DISCOMs shall alter the schedule of generation /requirement and intimate the same to SLDC for forwarding the same to NRLDC for incorporation in final drawal schedule of Delhi. By 22:00 Hrs — SLDC shall inform the modification if any, for incorporating in the final drawal schedule to NRLDC. By 23:00 Hrs — NRLDC issues the final drawal schedule of Delhi state along with other states and posted in their website. By 23:30 Hrs — SLDC shall compute the drawal schedule of DISCOMs and generation schedule of GENCOs based upon the availability from central sector stations and bilateral agreements entered into by various distribution licensees for the next day.

Provided that Intra-day scheduling as per IEGC provisions is also permitted.

IPGCL further informed that as far as overhauling of machines was concerned, they placed purchase order for spares and services in time bound manner to OEM, M/s BHEL. However, even after regular follow up with BHEL, the spare could not be made available. The representative of IPGCL assured that all out efforts are on to complete the over hauling of both the machines by March 2015 so that the full

generation is made available during crucial summer months. The Unit-1 of the plant would be taken under shut-down for carrying necessary over hauling on 30.12.2014 for about two months. They were of the view that neither SLDC nor the beneficiaries have any role to maintain the environmental stipulations in running the plant and it is the responsibility of IPGCL to meet the environmental stipulations. As such, the DC be certified as per the DC provided by the plant on day ahead basis.

Distribution Licensees strongly objected the views of IPGCL as the plant was closed down to meet the environmental stipulations due to non carrying out of maintenance activities to meet the environmental stipulations.

BRPL representative mentioned that the plant has already achieved its full life and permanent closure of the plant is pending in view of transmission constraints and the plant was shut-down on 01.10.2014 as decided by Govt. of Delhi. He also referred the DERC Regulation ‘Terms and Conditions for Determination of Generation Tariff’ dated 19.01.2012 for definition and interpretation of Declared Capacity and Plant Availability Factor as under:-

Declared capacity or DC in relation to a generating station means, the capability to deliver ex-bus electricity in MW declared bysuch generating station in relation to any time block of the day or whole of the day, duly taking into account the availability of fuel or water, and subject to further qualification in the relevant regulation.

Plant availability factor in relation to a generating station for any period means the average of the daily declared capacities (DCs) for all the day during that period expressed as a percentage of the installed capacity in MW reduced by the normative auxiliary energy consumption.

Based on the above, he claimed that the plant availability is zero not 50% as certified by SLDC on provisional basis as the plant is not capable to deliver ex-bus electricity due to environmental stipulations so that the consumers of Delhi are not burdened with charges even though not a single unit of electricity is availed from the plant from October 2014 till date.

BYPL also supported the views of BRPL.

TPDDL representative wanted to know about the actual capacity available at the time of peak summer this year. SLDC representative mentioned the figures already available in the agenda as under:-

After seeing the data, TPDDL representative was of the view that availability claimed by IPGCL for the month of October 2014 was 79.26% and for November 2014 as 79.23% which has not been achieved during peak summer demand period i.e. July 2014 and August 2014 and if the availability is to be certified, it should be average of April 2014 to September 2014 i.e. 65.82% that too as a special case.

IPGCL representative pointed out the figures of higher availability during April 2014 to June 2014 when power demand was high. They further cited that the lesser availability during July 2014 and August 2014 was attributable to the poor quality of coal in monsoon season and requested for certification of availability at least of average of April to June 2014.

After deliberations, considering the overall situation, it was decided to certify the availability of October 2014, November 2014 and upto 29.12.2014 (till unit- 1 has been taken on overhauling) as 65.82% or the actual availability claimed whichever is less and after that as per the availability declared by the station. SLDC was advised to revise the accounts accordingly. IPGCL was also advised to carry out all necessary maintenance works for both the units by 31.03.2015 so that units are available during peak summer season.

Representatives of Distribution Companies expressed their concerns in slippage of timelines. They requested to priotize the commissioning of 220kV Mundka – Peera Garhi Double Ckt cable, 220kV Peera Garhi – Wazipur D/C line, augmentation of two 100MVA Txs at Pappankalan-I, commissioning of additional 100MVA Tx at Masjid Moth, commissioning of additional 66kV Bays at Kanjhawala, LILO of at least one circuit between Sarita Vihar and Pragati at Maharani Bagh before summer 2015 without which they apprehend load shedding in summer months when the demand is expected to cross 6400MW.

DTL representatives informed that the commissioning of 220kV Mundka – Peera Garhi D/C line is on the top priority. With the commissioning of this link, the congestion at Najafgarh, Pappankalan-I & II would be eased. The commissioning of 220kV Gazipur – Patparganj single ckt line would also ease the congestion of 220kV Ballabhgarh – BTPS – Sarita Vihar – Pragati link and crucial loading of this summer season would be passed off in the existing arrangements.

All Stakeholders requested DTL to update the status of projects to be commissioned to meet the summer 2015 demand be updated in monthly OCC meetings for which DTL agreed.

However for voltage regulation they have planned additional capacity at LT level for 2013-14. Total 473.6 97.56

As per the CPRI study, no additional capacitor is required to be installed in Delhi, however, it was recommended that certain capacitors are required to be re- orientated. Proper maintenance of the existing capacitors was also recommended. To control high voltages, it was recommended to install proper capacity reactors.

General Manager(O&M)-I intimated that the study report of CPRI has already been forwarded to the stakeholders including NRLDC.

After discussion, it was decided to hold a meeting of all stakeholders of Power System of Delhi, Power Grid, NRLDC at SLDC Conference Hall as early as possible to chalk out further strategy on the recommendations as decided in the NRPC Forum.

3.4 NON AVAILABILITY OF 66KV BAYS AT 220KV KANJHAWALA S/STN (Agenda by TPDDL)

The representative of TPDDL informed that a bay was allotted for 66kV Ghevra Ckt-II Circuit is completed at TPDDL end and circuit is back charged to DTL end but the bay work is not completed a DTL end (Kanjhawala end).

Due to non availability of bay at 220KV Kanjhawala, the circuit is back charged up to Kanjhawala. It was further informed that the scheme has already been delayed more than two years and requested to yearly commissioning of the bay.

The representative of Planning Deptt. DTL informed that all out efforts would be made to commission the bay by the end of June 2015 (as only one bid was received on tender opened on 29.12.2014 and 15.01.2015 and hence again has been extended upto 30.01.2015).

3.5 NO ALTERNATE SOURCE AT 220KV SUBZI MANDI (Agenda by TPDDL)

TPDDL representative informed that in the present situation, 220kV Subzi Mandi is fed through two radial feeders namely 220kV Gopalpur - Subzi Mandi double ckt line. There is not alternate source for 220kV Subzi Mandi. Total 31 instances of supply fail reported at 220kV Subzi Mandi during the period April 2014 to October 2014 due to various reasons and on an average 15 minutes time has been taken to restore load. Sometime, it goes beyond 30 minutes also.

The Planning Department, DTL informed that the second feed of Subzi Mandi is envisaged from the upcoming 400kV Inderlok S/Stn being executed as ISTS. The outgoing feeder from Inderlok is also to be established by PGCIL. The system is likely to be commissioned by 31.03.2017 till then the existing system would continue.

3.6 OVER-LOADING OF 220KV MANDOLA – GOPALPUR CIRCUITS. (Agenda by TPDDL)

There was continuous over-loading at 220kV Gopalpur – Mandola circuits during peak summer time due to which TPDDL had to carry out unnecessary load shedding

to avoid over loading of 220kV Mandola – Gopalpur D/C. It may also address by providing alternate source at Subzi Mandi and take load of Subzi Mandi on it.

The establishment of 220kV Sanjay Gandhi Tr. Nagar S/Stn is envisaged in the fast track project to be established as TBCB in the year 2015-16. This would ease the over-loading of 220kV Mandola – Gopalpur Ckts. Further, upto the commissioning of 220kV Harsh Vihar – Preet Vihar – Patparganj link, more power can be evacuated through 220kV Wazirabad – Gopalpur link, would ease loading on 220kV Mandola – Gopalpur Ckts.

TPDDL was also advised to explore the possibility in taking part of TBCB process by their sister transmission concern so that the project can be executed by them and expedite the earlier commissioning of the sub-station and associated transmission system.

3.7 DISPENSING OF BTPS AND GT GENERATION (Agenda by TPDDL)

TPDDL informed that on account of transmission constraints, BTPS and GT both come under must run plant status. DTL should provide the target date for overcoming transmission constraints because of which both the plants come under must run status. The present cost of BTPS is Rs.5.20/Unit whereas that of Gas Turbine units is Rs. 5.60/Unit.

Planning Department of DTL informed that 400kV Tuglakabad S/Stn is envisaged under ISTS and expected to be commissioned by 2016-17, the S/Stn and the evacuation system from the 400kV Tuglakabad S/Stn would definitely ease the transmission constraints around BTPS area for which the generation of BTPS is required to be maintained during peak summer season.

As far as GT Station is concerned, this generation could be dispensed after commissioning of 400kV Rajghat S/Stn which is also being established as ISTS. After the commissioning of 400/220kV S/Stn at Rajghat and commissioning of 220kV outlets from Harsh Vihar 400kV S/Stn, the generation from GT can be dispensed with.

However, the dispensing of all such generation at load centre needs to be looked into in respect of reliability of supply and Islanding Scheme of Delhi.

SLDC representative mentioned that Gas Turbine Station of IPGCL has the facility of black start and hence SLDC has opined that atleast one module of GT generation should be always made available to take care of the exigencies.

The representative of SLDC further opined that as far as BTPS is concerned, atleast two units of 210MW capacity should be made available for reliability purposes. It was also presented the load generation balance for the peak period for 2014-15 upto January 2015(as detailed hereunder), the internal generation is almost 20-25% for the peak demand which is the bare minimum to ensure the reliable supply to the capital. 68

It was also brought out that total generation within Delhi is 1500MW against the requirement of 6000MW peak. Thus, about 75% of the power is being brought from outside the states. As such, any ripple in the Grid affects the reliability of the power supply of the Capital. The Government and other agencies are striving hard 69

to ensure reliable supply to Delhi for which internal generation is required to be augmented. An Islanding Scheme has also been devised to safeguard the power supply of Delhi after the massive Grid collapse occurred on 30/31.07.2012. As per the Clause 5.6 of the Islanding Scheme, the internal generation is required to be enhanced. The said clause is appended hereunder:-

5.6 Additional generation at load centres: Over the last few years, there has been loss of generation capacity of about 360 MW due to closure of Rajghat TPS and IP units. To reduce dependence of Delhi from outside the state, decision needs to be taken to build up the capacity within the state which would also help in meeting critical loads in emergency. (Action: Delhi Govt, Time Frame: 6 months)

After deliberation it was a general feeling that atleast the percent level of generation is required to be maintained even after commissioning the proposed 400kV ISTS in the capital as merit order generation is not only the criteria in respect of providing stable supply.

3.8 ASSESSMENT OF ACTUAL ENERGY AND DEMAND SHORTAGE BY SLDCs

SLDC informed that a meeting was held on NRPC on 16/18.09.2014 at NRPC on the issue of demand and shortage assessment by SLDCs. IEGC section 5.3, 5.4 and 6.4.5 mandates the states for estimating their demand in 15 minutes time block for balancing load and generation during real time Grid conditions. It was also decided to forward the Formats-1 to NRLDC by 19.00hrs. for the next day and Format-2 on next day by 04.00AM for the previous day. The details of Format-1 are as under:-

It was further elaborated that though the responsibility of giving the above data is SLDC, the Distribution Companies need to give the above information of their area so that SLDC can aggregate the same and forward to NRLDC.

SLDC vide its letter dated 24.09.2014 requested all discoms to provide the information but sofar the data is not forthcoming.

The representative of the distribution licenses informed that Format-I could be provided immediately however, Format-II is not possible due to absence of telemetry of all sub-stations of their distribution system due to which actual load of the distribution system is possible only after getting the SEM data which is at present being provided after 4 to 5 weeks.

After discussions, it was decided to provide the data by distribution companies in Format-I with immediate effect and Format-II be provided by SLDC considering Delhi as a whole for which the data of actual load of Delhi is available in the SCADA system of SLDC.

3.9 REPLACEMENT OF CONDUCTORS OF 220KV NARELA – ROHTAK ROAD DOUBLE CKT LINE.

The issue is that for enhancing the capability of 220kV lines between Narela and Rohtak Road being old Goat Conductors, the shut-down of both the circuits is required for about six months. During the shut-down, the 33kV Rohtak Road S/Stn of TPDDL which is having about 100-120MW load left with only 33kV sources affecting the reliability of supply of the areas fed from the Rohtak Road S/Stn. It was suggested that to ensure the additional feed, on the circuit between Wazirpur and Peera Garhi could be considered LILO at Rohtak Road for which the matter has to be taken up with BBMB authorities.

The representative of the Planning Deptt. of DTL informed that by 2015-16 the outlet from the 400kV ISTS at Inderlok (earlier Karampura) to 220kV Rohtak Road S/Stn. is proposed to be established. As such, the proposal of LILO of 220kV Wazirpur - Peeragarhi (one circuit) is dropped. For the proposal of the re- conductoring of existing 220kV Narela - Rohtak Road D/C Line with HTLS conductors, BBMB is being requested.

GCC advised DTL to expedite the HTLS re-conductring of 220kV Narela- Rohtak Road D/C Line for reliability of supply, it was also emphasized the timely completion of proposed 220kV outlet from the upcoming ISTS from Inderlok to Rohtak Road.

3.10 SHUT-DOWN OF TRANSMISSION / DISTRIBUTION LINES TO BE AVAILED BY DMRC

SLDC informed that DMRC plans shut-downs of EHV lines at short notices in connection with DMRC works. It was further informed that IEGC Clause stipulates planning of shut-downs should be done on yearly basis.

5.7 Outage Planning

5.7.1 Introduction c) Annual outage plan shall be prepared in advance for the financial year by the RPC Secretariat in consultation with NLDC and RLDC and reviewed during the year on quarterly and Monthly basis. All, Users, CTU, STU etc shall follow these annual outage plans. If any deviation is required the same shall be with prior permission of concerned RPC and RLDC. The outage planning of run-of-the-river hydro plant, wind and solar power plant and its associated evacuation network shall be planned to extract maximum power from these renewable sources of energy. Outage of wind generator should be planned during lean wind season, outage of solar, if required during the rainy season and outage of run-of-the river hydro power plant in the lean water season.

NRPC has further decided that all shut-downs involving inter states system should be forward to them to consider in NRPC OCC meeting by 5th of every month for the shut-downs to be matured for subsequent months. Further, it should be confirmed before 7 days to NRLDC to get the final clearance from NRLDC.

DMRC representative was not present in the meeting as the representative was busy with some other important meeting. However, Chief Engineer visited SLDC on the subsequent day and given the plan for shut-down of 220kV and 400kV lines. He informed that the advance planning of shut-downs is very difficult due to the nature of works and timing of shut-downs requirements. However, looking into the Grid stipulations, he agreed to draw out the plans at least a month ahead. He hinted about the requirement of following shut-downs: i) 220kV Sarita Vihar – Pragati D/C line during the period 27.01.2015 to 31.01.2015 in connection with DMRC work of line-8. ii) 400kV Dadri – Ballabhgarh D/C line for 30 days in connection with the work of line-8 (Janakpuri – Botanical Garden, Noida). Entire Maharani Bagh S/Stn would be left without 400kV infeed during the shut-down period. iii) 400kV Mundka – Bawana Ckt-I & II for Phase-III expansion of DMRC. The shut-down is required for about 30 days.

Chief Engineer, DMRC was informed that for (ii) and (iii) above, the approval is required to be given by the Regional OCC. It was also made very clear to him that without ERS, the shut-downs of (ii) and (iii) above is not possible looking into the stability of the entire Grid apart from maintaining power supply of the Capital. It was also advised that all the shut-down programmes should be completed by 31.03.2015 beyond that it is not possible to allow the shut-downs due to picking of summer demand. He was accordingly advised to draw out the plan.

3.11 STABILITY OF IP STATION.

SLDC informed that due to frequent outages of various 220kV and 33kV system of IP Station, the electrical supply of the areas fed from IP Stations gets affected apart from posing stability threat to the generating stations. It is understood that the trippings are mainly due to the act of miscreants such as theft of control cables, capacitor banks cells etc.

There were about 49 interruptions on 220kV side and 29 interruptions on 33kV sides during the period April 2014 to 05.10.2014. The 33kV 10MVAR capacitors are also out from April 2014.

The generating utilities and Distribution utilities expressed their concerns and requested the O&M Department of DTL for proper safeguard to avoid trippings at IP Station and thereby ensuring continuity of supply to the consumers of the areas fed from the station.

O&M Department of DTL informed that they have taken certain measures to avoid the trippings due to control cable issues and the results were seen by way of reduced trippings from 1st Week of October 2014. All out efforts are on to establish the new control room at IP Station and shifting of the cables by end of December 2015.

GCC advised the concerned O&M Department of DTL to ensure the stability of power supply of IP Station by all means.

Some utilities are not clearing the outstanding dues. Further, the non payment of DSM account is violation of DERC order dated 10.10.2007 and 22.08.2008 in this regard. The relevant DERC orders in the matter of non payment of dues by BRPL are appended hereunder:-

Relevant portion of DERC order dated 10.10.2007

13 The Commission is not convinced with the arguments of the BRPL that they have financial distress which is keeping them back from paying to UI pool, because electricity over drawn under UI is being billed and collected from the consumers. However, in order to make the present ABT mechanism work, the utilities should pay the amount as per SLDC statement for the UI charges. The Commission, therefore, directs the BRPL to pay the amount to the UI pool as follows:-

a) The amount due shall be paid on weekly basis as and when raised by SLDC to avoid accumulation of the outstanding dues and; b) The outstanding / accumulated dues shall be liquidate immediately with interest payable thereon.

Relevant portion of DERC order dated 22.08.2008

4. In view of the submissions of both the parties, the BSES Rajdhani Power Ltd. is directed to make regular payment of current UI charges and liquidate all outstanding dues towards UI charges within three months from the date of this Order. BRPL is also directed to pay interest on delayed payment as per the prevalent norms. It is further observed by the Commission that timely payment of UI charges is essential to keep the entire UI mechanism intact and fully operational. In future, due care must be taken to avoid accumulation of dues towards UI charges.

It was also brought out that in Petition no. 48/2014 filed by TPDDL, DERC has also directed SLDC to initiate steps to recover the dues of BRPL. The relevant order is appended hereunder:- ORDER (Date of Hearing: 09.12.2014) (Date of Order: 29.12.2014)

1. Mr. Alok Shankar, the Ld. Counsel for petitioner, submitted that the Central Electricity Regulatory Commission in its order dated 02.07.2014 in Petition no.143/282-MP-2013 directed that “The dispute regarding non-payment of UI dues by some of the intra-state entities to DTL and consequently, non-settlement of the dues of other distribution licensees of Delhi does not fall within the jurisdiction of this Commission. The petitioners are at liberty to approach DERC for appropriate relief in accordance with law if so advised.”

2. Mr. Shankar further submitted that approximately Rs.1.26 crores is receivable by the petitioner from the intra-state entities.

3. Mr. Susheel Gupta for SLDC submitted that the principal amount has been paid to the petitioner and only the interest is pending due to the non-payment of Unscheduled Interchange Charges (UI charges) by BRPL.

4. The Commission is not convinced with the contention of SLDC. The Commission is of the considered view that since SLDC has separate agreements with all the intra-state entities drawing power from the grid therefore it is their obligation to pay the outstanding interest to the petitioner without mixing it up with the non-payment of UI charges by BRPL. The Commission directs SLDC to pay outstanding interest to the petitioner within a month and also take appropriate action to recover the outstanding dues towards UI charges from BRPL.

5. With the above directions, the petition is disposed off.

6. Ordered accordingly.

SLDC also brought out that even BYPL had approached CERC vide petition no. 282/MP/2013 for getting their UI dues. The Commission vide its order dated 02.07.2014 had directed to approach DERC as all the dues of NRLDC have already been paid to Delhi. The relevant portion of the order is appended hereunder:-

12. In our view, the prayers of the petitioners for directions to NRLDC no more survives as the entire UI dues payable to DTL have been settled by NRLDC. The dispute regarding non-payment of UI dues by some of the intra-State entities to DTL and consequently, non-settlement of the dues of other distribution licensees of Delhi does not fall within the jurisdiction of this Commission. The petitioners are at liberty to approach DERC for appropriate relief in accordance with law if so advised.

13. Petition No. 143/MP/2013 along with IA Nos. 38/2013 and 3/2014 and Petition No. 282/MP/2013 disposed of in terms of above.

It was also brought to the notice that in fact now BYPL was also defaulting and with a substantial amount of Rs. 21 Crores as on date.

BRPL and BYPL representatives informed that due to financial crunch, they could not be able to pay the dues. However, it was assured that once they could able to muster additional financial resources through loans etc, they could be able to clear the dues.

MES representative assured that the payment would be released soon.

IPGCL / PPCL representative requested for earlier reconciliation of UI / DSM payment as it could not be done despite various efforts since last two years.

After deliberations, the following decisions have been taken:-

i) All defaulting utilities were advised to clear the dues immediately as directed by CERC / DERC so that the intrastate UI / Deviation Settlement Mechanism works smoothly in Delhi. ii) Reconciliation of interest for 2013-14 (for which data has already been forwarded to all utilities by SLDC through email be checked by all utilities) be reconciled with SLDC by the end of January 2015 and after that the interest payment would be disbursed or adjusted as per the direction of DERC in petition no. 48/2014. iii) The settlement of interest would be on the basis of interest computed on yearly basis as decided in previous meetings.

4.2 COMPENSATION FOR TRANSFORMATION LOSSES BETWEEN DISCOMS IN INTER DISCOM TRANSFER (agenda by BYPL)

BYPL vide their letter dated 17.02.2014 has requested the Commercial Sub- Committee to consider the transformation losses for inter discom transfer of power from July 2002 onwards. It was further clarified that at 11kV level, 1178MUs energy exported to TPDDL from July 2002 to September 2013. The transformation losses come to 23.56MUs. It has further clarified that the energy transfer from 66kV to 33kV and export to TPDDL through 2 nos. 33kV and 66kV Shastri Park Grid losses comes about 12.792MUs. At 33kV level, 640MUs exported to TPDDL through two 33kV circuits from 66kV Shastri Park Grid and the loss comes to 12.792MUs.

Apart from above, at 220kV Park Street, two 30MVA 66/33kV transformers are on standby mode for which no load losses / transformation losses are borne by BYPL. The same should be shared by all beneficiaries according to their energy drawal. They have proposed that credit of 36.52MUs be given for the past period and the transformation losses be applied in future bills. They have given the illustration also for arriving the figure:-

S. Scenario / case BYPL’s proposal N 1 Energy import at 66kV at 66/33kV at one No change in metered data Discoms and export at 66/33kV to another Discom without any transformation 2 Energy import at 66kV at one Discom and Transformation loss of 2% to export at 33/11kV to another Discom after be added to the metering data transformation 3 Energy import at 33kV at one Discom and Transformation loss of 2% to export at 11kV after transformation be added to the metered data.

The issue was discussed in the 14th Commercial Sub-Committee meeting held on 27.03.2014 in which the issue could not be resolved.

TPDDL was of the view that such type of transfer occurs for which adjustment would be very difficult and the existing practice should continue. Further, the 2% transformation loss appears to be more as normally the transformation loss is of the order of 0.5%. IPGCL and PPCL representatives also seconded the views of TPDDL.

DTL representative further informed that DERC vide their letter dated 19.11.2013 has mentioned that in the meeting held on 29.08.2003 with CEOs of Discoms, it was decided that Discoms shall meet their load from their own system / their own grid stations and would prepare an action plan to shift the load to the respective Grid station within three months. Further, in the coordination forum meeting held on 29.08.2005, it was directed that the shifting should be accomplished before the end of Mach 2007. It is also intimated that on the basis of the decision, the Commission has not even approved the enhancement of the transformation capacity at 11kV level to meet the load requirement of the areas fed from DTL’s sub- stations. As such, the above adjustment now requested should not be acceded.

After hearing the views of other stakeholders, BYPL requested for prospective adjustment as suggested above as the issue was discussed in Metering Coordination Committee meetings earlier and hence be referred back to Metering Coordination Committee.

After discussions, it was decided to continue the existing practice of energy accounting and requested to avoid transfer through inter discom network as directed by the Commission.

4.3 O&M CHARGES REGARDING INSTALLATION & MAINTENANCE OF NUMERICAL RELAYS (agenda by DTL)

TPDDL explained that as per the Protection Philosophy, the current differential relays are installed by TPDDL in their system as the distance protection which is the main protection is not effective for short lines. To match the relays, the TPDDL has installed relays at DTL’s sub-stations to work the system effectively. This was 84

done as per the decisions taken in various OCC and Protection Committee meetings held at DTL.

After installation, DTL has to maintain these relays. In the 15th Commercial Sub- Committee meeting held on 11.09.2014, it was decided to forward the case to GCC for approval of incurring O&M expenses of these relays installed at DTL’s sub- stations as additional O&M expenses for claiming through ARR of DTL.

To a query to BRPL, BYPL and NDMC, it was informed that they have not installed any current differential relays.

After discussions, it was decided that as O&M expenses of current differential relays being the miniscule expenses and as capital expenses of installation of current differential relays at DTL sub-stations is on the account of TPDDL the maintenance expenses if any, be borne by DTL from normal O&M expenses allowed by the Commission.

4.4 ADJUSTMENT OF SHORT TERM OPEN CHARGES IN MONTHLY WHEELING CHARGES BILLS OF DTL (agenda by Discoms)

In the 15th Commercial Sub-Committee meeting held on 11.09.2014, Distribution Companies have informed that the proper credit is not being given in the monthly bills of wheeling charges of DTL as per the Multi Year Transmission Regulations notified by DERC from January 2013. Clause 6.13 of MYT Regulation is reproduced hereunder:- 6.13 25% of the charges collected from short term open access customer shall be retained by the transmission licensee and balance 75% shall be considered as non tariff income and adjusted towards reduction in the transmission service charges payable by the long term and medium term users.

In the meeting, it was informed that the Finance Department of DTL informed that the STOA charges have been adjusted in the respective past dues to which representatives of Discoms informed that the same credit / adjustment is not reflecting in outstanding dues statement.

BYPL informed that since October 2012, the credit has not been passed on to Discoms as per the above provisions of MYT. They informed that as per data available with them, they have to be reimbursed the amount to the tune of Rs. 24.86 Crores upto March 2014 as detailed hereunder:-

FY Period Total Receipt by DTL Credit to be given to BYPL (Crores) (Crores) 2012-13 Oct-12 to Dec-12 22.79 4.36 Jan-13 to Mar-13 20.63 3.95 2013-14 Apr-13 to Sep-13 37.185 6.82 Oct-13 to Mar-14 52.39 9.73 2014-15 Apr-14 to Dec-14 Details not given by DTL -- Total 132.995 24.86 (Oct 2012 to March 2014) 85

They requested for above credit including April 2014 to December 2014 in subsequent bill of wheeling charges to be payable by BYPL to DTL.

DTL informed that the matter was discussed in last Commercial Sub-Committee meeting held 11.09.2014 wherein it was intimated by DTL that as intimated by Finance Department of DTL, they have adjusted against the outstanding dues of the utilities as the utilities owe huge outstanding dues to DTL due to which DTL is facing severe cash crunch even to meet the day to day expenses including O&M activities to maintain power supply of Delhi.

TPDDL representative objected the views of DTL and informed that in the joint reconciliation statement of outstanding dues, the credit of open access charges has not been reflected. They requested adjustment of dues with interest for the period January 2013 to December 2014. It was also requested that monthly adjustment should be done as is being done by PGCIL in case of open access charges credits for regional transmission system’s used for open access transactions on monthly basis as and when the amount is received from the RLDCs to DTL account for the transmission charges of DTL for open access transactions.

After deliberations, GCC advised the Commercial Department of DTL to immediately reconcile the credit to be given in the transmission charges with the Discoms involved and the process should be completed by end of January 2015. It was also advised that the credit should be reflected on monthly basis in the monthly bills being raised by Commercial Department of DTL as is being done by PGCIL in their regional transmission charges bills.

4.5 PAYMENT OF NRLDC CHARGES (agenda by NRLDC)

A) NON PAYMENT OF CHARGES BY PPCL FOR BAWANA POWER BEING SCHEDULED TO PUNJAB AND HARYANA

NRLDC representative informed that they are raising the RLDC Fee & Charges bills to Generating stations & Sellers as well as Distribution Licences & Buyers in line with CERC (Fee & Charges of Regional Load Dispatch Centre Regulations, 2009. The bills being raised to Delhi Control Area (through SLDC) since April 2014 onwards has the following three components:- 1 System Operation (SO) Charges for Distribution Licences 2 Market Operation (MO) Charges for Delhi Control area as a Single User. 3 System Operation Charges for Delhi as Seller (PPCL).

SO Charges from Delhi Control Area as Distribution Licences are being billed in proportion to the sum of allocations & contracted capacities. MO charges are being raised to Delhi Control Area as a single User. Delhi Control Area (PPCL) as a seller has LTA quantum of 137.12 MW with Haryana & Punjab each, as such SO charges for 274.24 MW in seller category are being billed to Delhi Control Area(PPCL) in line with Regulations 22(3) i.e.

System Operation Charges for Delhi as Seller (PPCL) are due since April 14 bill. The total outstanding amount up to October 2014 bills is Rs 17,14,607/. Delhi as Seller (PPCL) was requested to release the outstanding amount at the earliest.

PPCL representative was of the view that the scheduling of power from Bawana power plant is being done by Delhi SLDC to Punjab and Haryana also as per Clause-6.4.(2)(iii) of IEGC notified by CERC. The relevant clause of IEGC is reproduced hereunder:- iii) If a generating station is connected both to ISTS and the State network, scheduling and other functions performed by the system operator of a control area will be done by SLDC,, only .if state has more than 50% Share of power, the role of concerned RLDC, in such a case, shall be limited to consideration of the schedule for inter state exchange of power on account of this ISGS while determining the net drawal schedules of the respective states. If the State has a Share of 50% or less, the scheduling and other functions shall be performed by RLDC

He was also of the view that Bawana does not fall in the category of ‘Seller’or Úser’ (as per the clause 3(22) and 3(25) respectively. The clause 3(25) of Fee and Charges Regulation is reproduced hereunder:-

(25) ‘Úser’ means the generating companies, distribution licensees, buyers, seller and interstate transmission licensees, as the case may be, who use the inter-state transmission network or the associated facilities and services if National Load Dispatch Centre and Regional Load Dispatch Centres.

PPCL representative further affirmed that since scheduling of power of Bawana is done by Delhi SLDC and Bawana CCGT does not fall under the category of User or Seller, the System Operation Charges being billed for contracted capacity of the station with Punjab and Haryana are not payable.

SLDC representative informed that it is only collecting and disbursing agency of NRLDC Charges. SLDC has already requested PPCL to release the payment to avoid payment of penalty and raise the issue in regional forum. However, payments have not been releases sofar. Hence, SLDC could not pay the full as claimed by NRLDC from Delhi control areas. He also quoted the relevant portions of RLDC Fee and Charges Regulations indicating that SLDC is the nodal agency for collection and disbursal of amount to NRLDC on behalf of the Distribution Utilities of Delhi. The relevant portions of the regulations are appended hereunder:-

22. Collection of SOC (1) The System operation charges shall be collected from the users as per the norms given below:- (i) Inter state transmission licensees: 10% of system operation charges; (ii) Generating stations and sellers: 45% of system operation charges; iii) Distribution licensees and buyers: 45% of system operation charges. (2) The system operation charges shall be levied on the inter state transmission licensees on the basis of the ckt.-km of the lines owned by them as on the last day of the month prior to billing of the month. (3) The system operation charges from the generating companies and sellers shall be collected in proportion to their installed capacity or contracted capacity, as the case may be, as on the last day of the month prior to billing of the month.

(4) The system operation charges from distribution licensees and buyers shall be collected in proportion to the sum of their allocations and contracted capacities, as the case may be, as on the last day of the month prior to billing of the month.

The respective State Load Despatch Centre shall collect the market operation charges from the distribution licensees within a state on behalf of the concerned Regional Load dispatch Centre and the same shall be deposited to the concerned Regional Load Despatch Centre.

SLDC representative was further of the view that Bawana is not the Distribution Utility, it can not own the responsibility of collection of dues of Bawana CCGT in respect of NRLDC Charges and reimbursed the same to NRLDC.

Replying to the issues raised by Bawana CCGT and SLDC, NRLDC representative was of the view that Bawana CCGT being the embedded generation of Delhi State and have contracted with Punjab and Haryana for supply of 10% capacity of the station, it is the responsibility of Delhi SLDC for collection and disbursal of the RLDC Charges. He further affirmed that the charges are levied on other states also where such composite scheme of generation and sale of power is taken place as that in the case of Bawana. He further, quoted the decision of NRPC Commercial Committee meeting held on 30.10.2014 wherein it was decided that Bawana CCGT should be considered as embedded utility of Delhi control area. The relevant portion of the minutes of the meeting is appended hereunder:-

ITEM-13

SOC and MOC of NRLDC for the month of April, May, June, July, August and September, 2014 for PPS-III, Bawana Power Plant

Representative of IPGCL/PPCL stated that since Delhi discoms had more than 50 percent share from Bawana Power Plant of PPCL, as per Clause 6.4 (2) (iii) of Indian Electricity Grid Code Regulation 2010 of CERC, the scheduling of power to Delhi Discoms, Haryana and Punjab was done by Delhi SLDC. He referred to Clause-3

(22) definition of ‘Seller’ and Clause-3 (25) definition of User of CERC fees & charges of Regional Load Dispatch Centre and other related matters Regulation, 2009. He stated that Bawana GBS did not fall in the category of Seller or User as scheduling of power from Bawana was being done by Delhi SLDC and based upon the energy account issued by Delhi SLDC, PPCL was raising energy bills to all its beneficiaries including Haryana and Punjab. Therefore, SOC and MOC charges raised by NRLDC were not applicable to Bawana Power Plant.

Representative of NRLDC agreed that Bawana GBS did not fall in the category of user for NRLDC. The user was Delhi Control Area and the bill raised by NRLDC was for Delhi Control Area. Delhi Control Area was selling power to Punjab and Haryana under MTA. Therefore, Delhi Control Area had to pay SOC and MOC charges.

After deliberations it was decided that the SOC and MOC bill will be raised to Delhi control area.

NRLDC representative further informed that the above decision was affirmed in the 33rd meeting of Northern Region Power committee held on 11.11.2014 and 29th meeting of TCC held on 10.11.2014.

However, SLDC representative was of the view that as per the regulations, it can take the responsibility only as nodal agency for collection and disbursal of charges on behalf of Discoms to NRLDC.

NRLDC representative agreed for billing directly on Bawana CCGT if PPCL agreed for it.

PPCL representative has not agreed the proposal of NRLDC for direct billing of charges on them and thereby remittance.

After deliberations, GCC advised PPCL to clear all the dues of NRLDC Charges and remit the amount to SLDC so that they can reimburse the same to NRLDC as these charges are reimbursable from the beneficiaries i.e. Punjab and Haryana. It also requested NRLDC to consider the waiver off surcharge on delayed payment as a special case for which NRLDC representative agreed to take up the matter with their management.

B TDS OF NRLDC CHARGES BY DISCOMS AND DELHI SLDC (DTL) (agenda by NRLDC)

NRLDC representative informed that SLDC is releasing the payment to NRLDC after deductions of TDS by Distribution Licensees & SLDC Delhi since Oct 2010 bills. Deduction of TDS by Distribution Licensees is not under the PAN of POSOCO as such the same is to be refunded back to POSOCO. SLDC Delhi is requested to refund such deductions to POSOCO. The issue was discussed in the 29th TCC and 33rd NRPC meeting held on 10.11.2014 and 11.11.2014 respectively wherein the following was decided:-

Dy. Manager (Finance), SLDC informed that SLDC has already forwarded the tax consultants’ advise obtained by them to NRLDC vide their letter dated 24.06.2011 and suggested the following remedial measures to avoid the double taxation issue:- a) Seek TDS exemption of double TDS from appropriate authority. b) Bill directly to Discoms based on the data to be provided by SLDC regarding apportionment of NRLDC Charges by Discoms, as is being contemplated in case of ISTS Charges scheduled to be started on the basis of PoC Charges methodology from 01.07.2011 (has already been from 01.07.2011).

But, so far, no reply / action has been taken by NRLDC on the above advise of Delhi SLDC.

M VERMA & ASSOCIATES 1209, Hemkunt Chambers CHARGED ACCONTANTS 89, Nehru Place, New Delhi-110019 Ph.26475905, Telefax 26211211 Email:[email protected] ______

The Deputy General Manager Delhi Transco Limited Shakti Sadan, Kotla Road, ITO New Delhi-110002

Sub : Deduction of TDS on payment of (i) Interstate Transmission Charges (ii) System Operation Charges & Market Operation Charges. Your Letter Dated 01.06.2011.

Sir,

This is with reference to your letter dated 01.06.2011 and subsequent discussion held with undersigned in our office at Nehru Place with regard to seeking our opinion for the recovery of TDS while releasing payment of charges to PGCIL / POSOCO after collecting / recovering the amount from DISCOMs as beneficiary. As per section 194J of Income Tax Act 1961 “Fee for Professional or Technical Services” i) Any person, not being an individual or Hindu undivided family, who is responsible for paying to a resident any sum by way of a) Fee for professional services, or b) Fee for technical services or c) Royalty, or d) Any sum refer to in clause (va) of section 28

Shall, at the time of credit of such sum to the account of payee or at the time of payment thereof in cash or by issue of cheque or draft or by any other mode, whichever is earlier deduct an amount equal to 10% of such sum as Income Tax on Income comprised therein

Further, as per clause (3)(b) “Fee for technical service” shall have the same meaning as in explanation 2 to clause (vii) of sub section (1) of section 9 i.e. “fee for technical service” means by any consideration (including any lump sum consideration) for the rendering of any managerial, technical or consultancy service (including the provision of services or technical or other personal).

We have perused the existing provisions relating to deduction of tax at source on technical services and we are of the opinion that the tax will have to be pad on each payment when it is subsequently made to the beneficiaries. This is no doubt a double taxation at this juncture, however this amount is refundable at the time of final assessment. For taking refund it is necessary to comply with all the provision and file all TDS return in time.

Please note as per the Law statue the only way to avoid double taxation is to seek exemption from the Appropriate Tax Authority.

Should you need more clarification, you are most welcome.

Thanking you Yours faithfully M. VERMA & Associates Chartered Accountants

Madan Verma Partner

Dy. Manager (Finance), SLDC was further clarified that TDS deducted has already been remitted with Income Tax Department.

Discoms also expressed the accounting issue if NRLDC bills to Delhi SLDC and Delhi SLDC further apportioned the amount amongst Discoms (i.e. further billing by SLDC to Discoms) and remitting the amount by Discoms to NRLDC directly to avoid double taxation. NRLDC also expressed their inability to bill directly on Discoms as all RLDCs bill the charges on one State Control Area.

The representative of MES was of the view that if NRLDC wants the present system of billing of NRLDC Charges, let the TDS be done as per the existing law which is going to the Consolidated Fund of India. NRLDC representative informed that in this case, the entire ARR is not recovered due to additional taxation and not even getting the benefit of tax deduction done by Discoms.

After discussions, GCC advised NRLDC representative to discuss the issue with Finance Department of SLDC as decided in NRPC Forum to resolve the issue amicably.

4.6 REVISION OF WHEELNG CHARGES INVOICES FOR THE PERIOD APRIL 2014 TO JULY 2014. (agenda by TPDDL)

TPDDL requested that DTL to revise the monthly invoices for April 2014 to July 2014 as per the Wheeling Charges of Rs. 207.39 Crores converted to monthly installments after adjusting the SLDC Charges. Due to deviation of billing from the ARR approved for Discoms for 2014-15 vide DERC order dated 23.07.2014, they are incurring about Rs. 2 Crores per month more than the ARR which they have to arrange through taking loans from Banks at applicable interest rates.

DTL informed that the bills are raised based on the approved ARR of DTL for 2014-15 vide DERC’s order dated 13.07.2012 which is as under:-

Table-42 (ARR approved by the Commission in Rs. Crores) Particulars FY 2014-15 Operation and Maintenance Cost 211.17 Depreciation 183.32 Rebate on Sale / Wheeling of Power 0.00 Income Tax 27.23 Total Expenditure 421.72 Return on Capital Employed 325.92 Less : Expenses capitalized 10.38 Less : No Tariff Income 2.50 Aggregate Revenue Requirement (for current year) 734.75 Additional Power Purchase Liability for prior period (2002-07) Payment to Pension Trust Aggregate Revenue Requirement (including prior period liabilities) 734.75

SLDC is separately raising the bill for SLDC Charges @ Rs. 9.03 Crores per annum based on the DERC order. It was also specifically mentioned how the Wheeling Charges are recovered from Distribution Companies which is as per weighted average entitlement as per the data provided by SLDC.

TPDDL was of the view that if DTL intends to raise bills as per MYT order dated 13.07.2012, it should not claim the Pension Trust contribution which is not the part of that order as evident from above. However, they are claiming the Pension Trust contribution based on the Discoms ARR order dated 23.07.2014 which amounts to Rs. 132.66 Crores per annum for TPDDL. As such, DTL can not adopt the pick and choose methodology i.e. transmission charges through the order dated 13.07.2012 and Pension Trust payment which is the part of transmission tariff adopted by DTL from ARR of Disocms based on the order dated 23.07.2014. He also informed that none of the letters written in this regard by TPDDL has been responded by Commercial Department of DTL.

The representative of Commercial Department of DTL informed that they have already taken up the matter after getting the reference from TPDDL through their letters dated 21.08.2014 and 05.09.2014 with DERC vide DTL’s letter dated

23.09.2014. Further, it was informed that Pension Trust payment has been given by the Commission as a special dispensation to meet the pensionary benefits to be discharged by DPCL – the Holding Company as such it was not the part of tariff order dated 13.07.2012 for DTL Transmission Tariff. The representative further informed that the matter was placed before Commission as under:- i) The Commission has made the following provisions of wheeling charges and SLDC charges in ARR of Distribution Companies as under:

Discom Wheeling + SLDC Charges approved by the Commission in Rs. Crores through order dated 23.07.2014 TPDDL 207.39 BRPL 296.89 BYPL 171.80 NDMC 36.74 Total 712.82

The ARR of SLDC is Rs. 9.03 Crores and considering the total of Rs. 734.75 Crores of ARR of DTL as per order dated 13.07.2012, the total liability of Discoms towards SLDC and DTL comes out Rs. 743.79 Crores. ii) The weighted average entitlement of all Distribution Utilities considered by Commission in its tariff order dated 23.07.2014 vis-a-viz actual is as under:-

Discom Weighted Average Entitlement Actual Weighted Average Difference in %age considered by DERC for 2014- Entitlement for 2013-14 as 15 in %age per SLDC in % TPDDL 27.883 30.408 2.525 BRPL 39.916 38.141 -1.775 BYPL 23.098 24.669 1.568 NDMC 4.940 5.827 0.887 Total 95.837 99.045 3.205

The weighted average entitlement of MES comes to 4.163% (to meet the 100% allocation) whereas the actual average of MES is 0.958% for 2013-14 and accordingly, the annual wheeling and SLDC Charges for MES comes to Rs. 7.12Crores. As such, the Commission has made less provision of Rs. 23.85 Crores [743.79-(712.82+7.12)] in the ARR of Discoms towards wheeling and SLDC Charges. iii) DTL is raising the bills based on the methodology specified by the Commission in the tariff order. And the bills are raised based on the weighted average entitlement of Discoms as per the data provided by SLDC only monthly basis. iv) The difference of Rs. 23.85 Crores is due to difference in weighted average considered by the Commission and as provided by SLDC. v) Considering the above facts, the Commission is requested to issue necessary directions to Discoms to pay full wheeling charges and SLDC charges i.e. Rs. 734.75 Crores and Rs. 9.035 Crores respectively.

Considering the overall facts, GCC requested TPDDL to settle the bills as per the tariff orders issued by DERC for DTL (Rs. 734.75 Crores) and SLDC Charges (Rs. 9.035 Crores per annum) separately as these charges are subject to truing up of expenses on actual basis. Commercial Department of DTL was further advised to approach the Commission for clarification. The Commercial Department of DTL was also advised to share the communication made with the Commission by DTL in this regard with the Discoms. Commercial Department of DTL was also advised to respond all such communication properly.

4.7 WAIVER OF DSM PENALTY ON ACCOUNT OF TRANSMISSION LINE TRIPPING (Agenda by TPDDL).

TPDDL raised the issue in the DPPG meeting held on 29.09.2014 with regard to waiver of penalty on account of transmission line trippings in DSM mechanism on Discoms. The representative mentioned the MoM of the said DPPG meeting as under:- 4 Waiver of DSM Penalty on Discoms on account of Transmission lines tripings.

On account of Transmission elements trippings, TPDDL mentioned that in number of occasions due to tripping of transmission elements such as 400kV and 220kV Transmission lines, 220/66kV, 220/33kV transformers resulting into loss of supply to large number of consumers causing huge under drawal of discoms. In DSM Regulations, penalty is envisaged for such under drawal if frequency is above 50.1Hz. The relevant portion of the DSM Regulations in this regards is as under:-

Cl.7. Limits on Deviation volume and consequences of crossing limits (4) In addition to Charges for Deviation as stipulated under Regulation 5 of these regulations, Additional Charge for Deviation shall be applicable for over-injection/under drawal of electricity for each time block by a seller/buyer as the case may be when grid frequency is ‟50.10 Hz and above” at the rates equivalent to charges of deviation corresponding to the grid frequency of “below 50.01 Hz but not below 50.0 Hz”.

It was also mentioned that if generation is affected due to transmission system outages, the DSM rates are not applicable for them. To have natural justice, the same provisions should be adopted for Discoms. TPDDL further informed that the matter was discussed in the meeting held on 19.09.2014 at DERC and also discussed during the hearing held on 26.08.2014 in Petition no.10/2014 at DERC in the matter of seeking appropriate directions under section 33(4) of Electricity Act 2003 to SLDC.

DPPG considered the suggestions and expressed its views in line with TPDDL but DPPG not being the competent forum, it was decided that SLDC will take up the matter in the Grid Coordination Committee meeting wherein the representation of DERC, NRLDC, Gencos etc is available for decision.

He requested the Committee for deliberation and decision.

NRLDC representative quoted the following provisions of Indian Electricity Grid Code Regulations to deal the issue:-

6.5 Scheduling and Despatch procedure for long-term access, Medium–term and short-term open access

16. In the event of bottleneck in evacuation of power due to any constraint, outage, failure or limitation in the transmission system, associated switchyard and substations owned by the Central Transmission Utility or any other transmission licensee involved in inter-state transmission (as certified by the RLDC) necessitating reduction in generation, the RLDC shall revise the schedules which shall become effective from the 4th time block, counting the time block in which the bottleneck in evacuation of power has taken place to be the first one. Also, during the first, second and third time blocks of such an event, the scheduled generation of the ISGS shall be deemed to have been revised to be equal to actual generation, and the scheduled drawals of the beneficiaries shall be deemed to have been revised accordingly.

17. In case of any grid disturbance, scheduled generation of all the ISGS and scheduled drawal of all the beneficiaries shall be deemed to have been revised to be equal to their actual generation/drawal for all the time blocks affected by the grid disturbance. Certification of grid disturbance and its duration shall be done by the RLDC.

The issue in this regard is that if penalty of under drawal of Delhi as a whole occurs, the same would be imposed on Delhi and Delhi SLDC has to compute the penalty for such under drawal to the internal utilities. If the penalty is waived off, in respect of under drawal of Distribution Company due to outage of a transmission system, the question remains that who should bear the penalty. In the existing methodology, Transmission Utilities are not the participants of DSM.

He suggested only to revise the schedules looking into the transmission constraints / trippings to avoid the penalty for such under drawals which would be implemented from 4th block as per the provisions of the Grid Code.

TPDDL was of the view that generating utilities are always insulated in the earlier UI / present DSM as these mechanism gets suspended in case of transmission constraints and the actual generation would be become the scheduled generation. He wondered why this mechanism was not possible for Discoms in case of under drawal due to transmission system outage in which Discoms have no control. He also pointed out that the backing down is possible only for generating stations and not applicable for additionally tied up power. They are loosing heavily on this account and should be compensated as the losses are occurring due to failure of transmission utility on which they do not have any control.

DTL representative was of the view that if a transmission system becomes defective, the transmission system availability gets reduced and if it is less than 98%, they cannot be able to recover the full wheeling charges and if goes below 98%, the wheeling charges would be reduced on pro-rata basis. As such, they are already being penalized in case they do not achieve 98% target availability fixed for recovery of full Wheeling Charges. He also informed the strengthening of transmission system already undertaken / being under taken as mentioned in the agenda and hoped that the event of failure of large quantum of consumer load due to transmission system outages would reduced considerably in near future.

Executive Engineer (Commercial), NRPC who was present at the time of discussion of the issue has mentioned about Standard of Performance of Interstate Transmission Licensees Regulations 2012 notified by CERC on 17.09.2012. Through this regulation, transmission licensees have to maintain certain parameters and adhere to maintain the standards failing which they are liable to pay compensation to the beneficiaries. The Standard of Performance is mentioned at Regulation-5 and compensation is mentioned in Regulation-6. The respective Regulations are reproduced hereunder:-

5. Standards of Performance (1) All inter-State transmission licensees shall comply with the Standards of Performance specified in these regulations: (a) Transmission System Availability (i) The transmission system availability shall be calculated element – wise on monthly basis, in the same manner as provided for in the Central Electricity Regulatory Commission (Terms and Conditions of Tariff) Regulations, 2009, as amended from time to time and any subsequent enactment thereof. (ii) The deemed availability of the transmission elements under outage shall be as specified in the Central Electricity Regulatory Commission (Terms and Conditions of Tariff) Regulations, 2009, as amended from time to time and any subsequent enactment thereof. (iii) The element-wise monthly availability of the transmission system shall not be below the availability as given below:

Sr. Transmission Element Availability No. (% of time) (i) AC Transmission Line 90 (ii) ICTs 90 (iii) Reactors 90 (iv) Static VAR Compensator 90 (v) Series Compensator 90 (vi) HVDC (Back-to-back Stations and bi- 85 pole links)

Notes: (1) Tower collapse shall not be counted for the purpose of calculation of monthly availability of AC transmission line and HVDC bipole line. (2) Failure of Inter-Connecting Transformer (ICT) and Reactor shall not be counted for the purpose of calculation of availability of Inter-Connecting Transformer and Reactor. 97

(iv) The element-wise monthly availability shall be certified by the Member Secretary of the Regional Power Committee. (b) Restoration time Restoration time for different types of failures of transmission line and Inter-Connecting Transformer (ICT) and reactors shall not exceed the following time limit:

Sr. Types of failures Restoration No. Time (Days) 1 Insulator failure Plain Terrain 1 Hilly Terrain 2 2 Tower after collapse by Emergency 12 Restoration System (ERS) 3 Tower after collapse Plain Terrain 30 River bed 50 Hilly Terrain 50 4 Snapping of phase conductor Plain Terrain 2 Hilly Terrain 3 5 Failure of earth wire Plain Terrain 2 Hilly Terrain 3 6 Failure of Inter Connecting Transformers (ICTs) Restoration of the failed ICTs 120 7 Failure of Reactors Restoration of the failed reactor 120

6. Any failure by the inter-State transmission licensee to maintain the standards of performance specified in these regulations shall render the said licensee liable to payment of compensation to an affected person claiming such compensation under the provisions of the Act:

Provided also that the payment of compensation by the Inter- State transmission licensee shall be without prejudice to any penalty, which may be imposed or any prosecution which may be initiated by the Commission as provided in the Act.

7. Methodology for compensation.- An affected person who has suffered a loss on account of non-adherence to the Standard of Performance by any inter-State transmission licensee may make an appropriate application to the Commission for award of compensation:

Provided that the Commission shall determine the compensation after giving reasonable opportunity to the transmission licensees of being heard:

Provided further that the compensation to be paid by the inter-State transmission licensee to the affected party shall be limited to the transmission charges of the particular element to the extent to which it has affected the supply of electricity to the affected person:

Provided further that the inter-State transmission licensee shall not be entitled to recover the amount of compensation awarded through tariff from the users of the transmission electricity:

Provided also that no claim for compensation shall be entertained if the application for the claim is filed after expiry of a period of ninety days from the end of the month when the availability of the transmission system falls short of the availability specified in Clause 5 (a) and ninety days from the date of restoration of transmission element, as the case may be, for the standards prescribed in Clause (b) of Regulation 5 of these regulations.

The representative of NRPC was further of the view that apart from above, no other penalties like compensation to Discoms due to financial loss in the DSM owing to failure of transmission system is applicable on the transmission utilities as per central regulation in this regard is concerned.

It was observed that no such regulations were made for performance of the state transmission utility in Delhi.

TPDDL representative requested SLDC to factor this issue also in their report to be submitted to DERC as directed in petition no. 10/2014.

Considering all the aspects, GCC decided to leave the issue for decision by DERC and also advised SLDC to include the gist of discussions in the report to be submitted in the petition no.10/2014 as directed by DERC.

4.8 MINIMUM TECHNICAL LIMIT OF COAL BASED GENERATION (agenda by TPDDL)

TPDDL informed that on the basis of directions of DERC on petition no. 10/2014 dated 03.09.2014 that TPDDL and SLDC should convene a meeting at a appropriate level and make efforts to resolve issues amicably. The petition was with regard to scheduling issues. The minimum technical limit of generation being schedule was also one of the issues.

TPDDL requested SLDC to intimate them about the minimum technical limit of coal based generating stations. There are certain days or slots during the day when they don’t need complete power allocated to them from these generating stations but are unable to ascertain as to how much power can be backed down. This issue is especially critical during winters. Currently, they are treating 70% of the allocated capacity as minimum technical but they need more accurate information to schedule power optimally as it affects the end consumers directly. They requested to update us the minimum technical limit of coal based generating stations and also the requirement provided by the other Discoms of Delhi for the next day so that the

minimum scheduling can be understood for planning the arrangement to meet the shortages and dispose off the surplus power.

MES representative indicated that they are also facing similar problem. The representative further indicated that MES is having surplus allocation (50MW from BTPS and 25MW from Bawana CCGT making the total of 75MW against the demand of 40MW). The additional allocation from Bawana CCGT was availed mainly due to the assumption that BTPS units are going to be closed down and they were advised to arrange additional power to meet the eventualities of closing down of units since long but still, BTPS units are running even after three years of making additional arrangement of 25MW from Bawana CCGT and is being scheduled more than the requirement placed by them on daily basis. Due to this, due to under drawal they are being penalized heavily and resulting into the Grid Code violation also. They indicated the loss of about Rs. 3 Crores per month apart from putting additional surcharge in Deviation Settlement Mechanism. The details of losses due to more scheduling than the requirement from BTPS as intimated by them are as under:- a) Demand / Consumption : 0.57MUs per day b) Actual scheduling : 0.74MUs per day c) Forced over schedule : 0.17MUs i.e. 29.27% d) Losses to MES per month : 0.17MUs X Rs.5.45=Rs. 9.2 Lacs per day i.e. Rs.2.87Cr. per month

It was further intimated by MES that they reserve right not to pay for over-allocated energy. They also wanted to know what was the requirement placed by Discoms and scheduled from BTPS.

SLDC intimated that just prior to the implementation of ABT in Northern Region (ABT has been implemented in Northern Region from 01.12.2002), the OCC meeting held in the month of November 2002 at NRPC has decided the minimum technical level of thermal and gas stations decided as under normal conditions minimum schedule could be 60% of MCR and under exceptional conditions, the same could be 50% of the Maximum Continuous Rating (MCR) in case of Gas Stations. And in case of thermal stations, the minimum schedule could be 70% of the MCR. These limits are applicable for central sector generating stations.

As far as Delhi Stations are concerned, in the coordination meeting held at SLDC, the minimum schedule for BTPS was fixed as 80% of MCR due to vintage and that of gas station of Pragati Stage-1 is also kept as 80% of MCR considering the pollution stipulations (NOX level). Bawana CCGT also can not go beyond 75% ex- bus capacity of the running units due to pollution stipulations. IPGCL gas station can not be scheduled less than 70% of ex bus capacity of running units due to stipulations due to technical constraints and pollution stipulations.

With regard to exhibiting the requirement of other distribution licensees, RLDCs are not showing the requisition of other states from the particular stations and they would exhibit the same in the website. SLDC further assured that from the date RLDC exhibits the requirement of other states on their website similar information would be exhibited in the website of SLDC. Further, SLDC reminded the distribution companies that as per the Grid Code, they should plan the load and availability based on their requirement of the consumer demand of their area and not the availability be maintained based on the requirement of other distribution companies’ consumer demand.

The surplus and shortage should be managed based on the available capacity on bars and load so that deviation from actual drawal from schedule drawal is kept minimum for maintaining the Grid discipline. It was also brought out that the requirement of other Discoms from the particular stations is not static as it depends upon availability from other sources and demand variation of the discoms.

With regard to points raised by MES with regarding to over scheduling, SLDC informed that at present 2X210MW machines are on bars with minimum schedule of 290MW. Since overall Delhi demand during night time is about 1600MW as per merit order none of the share holder of BTPS requires power. In this case, minimum requirement is scheduled to run the plant and is booked to all stakeholders as per their allocation. As such, MES is also booked minimum 20MW from the plant during night hours (off peak hours). During the peak hours when demand picks up every Discoms schedule full allocation from running units in that case the allocation to MES and other Discoms is being scheduled as per their requirement.

This is in the case of Bawana CCGT also. The minimum allocation to MES during off peak hours when one GT and its Steam Turbine generate power (280MW). The minimum allocation from Bawana CCGT to MES is 6MW thus the total allocation is 26MW which is against the requirement of about 18MW of MES. As per the Grid Code provisions, the utilities should visualize the minimum availability & load and the balance should be disposed off through various means. This responsibility lies with concerned Discoms not with other utility like SLDC or other Discoms. The SLDC representative reiterated that the surplus availability should be dispose off and additional power to meet their demand should be arranged to avoid penalties and to avoid indulging into Grid violations. He elaborated that against the total annual requirement of 28000MUs, availability was about 52000MUs during the year 2013-14 being the surplus about 46% of the availability and about slightly less than double of the requirement. This ratio falls with MES also. The other Distribution Companies including NDMC dispose off the surplus power during off peak hours and arrange additional power during peak hours to meet shortages. The details of the power surplus scenario of Delhi as a whole for 2013-14 are as under:-

With regard to closing of units at BTPS, representative of SLDC was of the view that the decision lies under the jurisdiction of Govt. of India and NTPC who owns the plant. It was further informed that there was a proposal to close Stage-1 units (3X95) of BTPs as the units have already completed the useful life and replace the same with 1050MW combined cycle gas station. The evacuation system was also finalized by CEA but due to the gas availability crisis in the country, it is understood that the proposal has been deferred. SLDC also brought out the Islanding Scheme of Delhi devised after the massive Grid collapse occurred on 30/31.07.2012, wherein maximization of internal generation has been stressed. He quoted the relevant clause of Islanding Scheme formulated during October 2012 as under:-

102

5.6 Additional generation at load centres:

Over the last few years, there has been loss of generation capacity of about 360 MW due to closure of Rajghat TPS and IP units. To reduce dependence of Delhi from outside the state, decision needs to be taken to build up the capacity within the state which would also help in meeting critical loads in emergency.

(Action: Delhi Govt, Time Frame: 6 months)

It was also intimated that at Govt. of India level also, lot of efforts were made to reallocate the surplus power of Delhi without affecting internal generation within Delhi. Even though, the 100% capacity of BTPS is dedicated to Delhi and is embedded generation of Delhi, it succeeded to reallocated 40% of the capacity to Madhya Pradesh though it was done for the period 01.10.2014 to 31.03.2015 but Madhya Pradesh did not agree to avail the same beyond 25.12.2014. However, it was succeeded to reallocate 180MW capacity of Dadri (Thermal)-I (TPDDL)’s share to Bihar from 10.09.2014 to 31.08.2015 and 261MW from Dadri (Thermal)-II to Bihar for the period 14.11.2014 to 31.03.2015. As such, MES is required to manage surplus and shortage based on the availability.

After deliberations, MES was advised to dispose off the surplus power considering the ground reality. In case, any shortage, they should arrange adequate power to avoid load shedding as the areas fed by them are of strategic importance and hence the stability of supply of MES area should be given priority over commercial implications. With regard to exhibit the requirement of power from different sources by Discoms on day ahead and real time basis, the same be exhibited in the website of SLDC from the day NRLDC does the same.

5 ADDITIONAL AGENDA

5.1 ANAMOLY IN ISSUING ENERGY ACCOUNTS OF RPH DURING OCTOBER 2014 AND NOVEMBER 2014 (agenda by IPGCL / PPCL).

5.2 NON PAYMENTS OF ENERGY BILLS BY BRPL AND BYPL SINCE OCTOBER 2010 (agenda by IPGCL / PPCL).

Already mentioned in Item no.2.3

5.3 OPENING OF LC FOR BULK POWER SUPPLY TO BRPL AND BYPL BY IPGCL AND PPCL (agenda by IPGCL / PPCL).

The representative of IPGCL / PPCL intimated that despite various efforts by them, the BRPL and BYPL have not established required LC for securing bulk power supply since April 2011. They requested these utilities to provide LC as per the provisions of PPA.

103

The representatives of BRPL and BYPL that they have already informed of the financial positions and the limitations fixed by the banks according to the financial position, they could not be able to establish LC. Due to precarious financial condition, they could not even be able to pay monthly dues of power supply and transmission utilities. The opening of LC could be possible after the financial position improves.

GCC advised IPGCL / PPCL to deal the issue as per the provisions of PPA

5.4 OPENING OF LC FOR BULK POWER SUPPLY TO TPDDL BY IPGCL AND PPCL (agenda by IPGCL / PPCL).

The representative of IPGCL informed that the LC for power supply from power stations of IPGCL / PPCL established by TPDDL expired on 31.03.2014. Various correspondences have been made by IPGCL / PPCL in respect of renewing the LC for securing bulk power supply. However, TPDDL have not established LC since 01.04.2014.

The representative of TPDDL informed that they are paying the entire dues of IPGCL and PPCL regularly. LC is for back up mechanism for securing the payment. The opening charges of LC are not passed through in the ARR. They have already intimated that if proper incentive as is being done by NTPC and other utilities for establishing LC is extended to them by IPGCL /PPCL, they are ready to establish LC.

IPGCL / PPCL representative expressed their inability as the provision of incentive by way of additional rebate in the monthly bills is not as per the provisions of PPA or tariff regulations.

GCC advised both the utilities to amicably settle the issue.

5.5 RECONCILIATION OF UI / DSM ACCOUNTS (agenda by IPGCL / PPCL) The representative of IPGCL / PPCL informed that the reconciliation of UI / DSM accounts and the account of diversion of UI Charges payable to BYPL to IPGCL / PPCL as per the advise of Govt. of NCT of Delhi against the dues of payment to them was pending since last two years. The representative further informed that the reconciliation was pending despite continues efforts.

The representative of Finance Wing of SLDC informed that the details upto 31.03.2014 have been communicated to all stakeholders and requested them to intimate any discrepancy for reconciliation and computation of interest charges.

GCC advised SLDC to reconcile the accounts upto 31.03.2014 by 31.01.2015 as decided in item 4.1.
