The list of participants is enclosed as Annexure-1.

WELCOME

Sh. Prem Prakash, Director (Operations), DTL, Chairperson, GCC welcomed all delegates in the 19th Grid Coordination Committee meeting. He hoped that the issues would be sorted out amicably.

He stated that the power supply position in the winter has been satisfactory by and large. This winter Delhi has met a peak demand of 4464MW on 05.01.2018 without any load shedding due to shortage of power.

He expressed great pleasure that DTL has strengthened its transmission network by augmentation of various transmission lines. With these arrangements, DTL would be able to meet summer peak successfully without any constraints. He expected that the peak demand of Delhi would be around 7000MW. He hoped that all utilities have made sufficient arrangements to meet consumer’s demand.

He further expressed his concerns on the non payment of dues by some of the Distribution licenses due to which generating and transmission companies are facing acute shortage of funds. He advised Distribution Companies to pay dues in time.

Concluding the remarks, he requested all the Stake Holders to actively participate in the proceedings of meeting for fruitful discussions and arrive at a considered decision to ensure secure and economic operation of the power system of Delhi. He advised Dy. G.M. (SO) to take up agenda for discussion.

Accordingly, the Agenda was taken up for discussion.

The gist of discussions and decisions are as under:-

1 CONFIRMATION OF THE MINUTES OF 18TH MEETING OF GCC HELD ON 22.09.2017.

The minutes of the 18th meeting of GCC held on 22.09.2017 have been circulated vide letter No. F./DTL/207/17-18/DGM(SO)/204 dt. 02.1.2018. BYPL vide their letter No. Adl VP/PMG/BYPL/2017-18/1563 dated 17.01.2018 has submitted their disagreement in reference to para 5.4(4) of MoM. The para 5.4(4) of MoM is reiterated is extracted here under:

4. Implementation of DERC directions on EDWPCL: As per the DERC letter no.F.9 (170)/DERC/DS/2016-17/5290/1091 dated 04.09.2017 regarding COD of EDWPCL Gazipur and adoption of Tariff, Point wise implementation strategy is proposed hereunder:

S.No DERC Implementation Decision of GCC 1 COD may be As per the minutes of meeting held GCC observed that as per PPA, the declared on between BYPL and EDWPCL dated performance for CoD was conducted on successful trial run 08.06.2017 the COD of EDWPCL is 25.04.2017 for a period of 72 hours. of this Waste to considered 28.04.2017 at 00.00 Hrs. However, plant could achieve 90% of rated Energy Plant at capacity (ex bus) for 24 hours. BYPL & 90% PLF for 24 EDWPCL in its meeting held on 08.06.2017 hours. mutually agreed to consider the CoD of the plant w.e.f. 00.00hrs. of 28.04.2017 by considering the test achieved for 24 hours on 27.04.2017 for consideration of CoD instead of 72 hours as required under PPA subjected to the approval of DERC. DERC vide its letter dated04.09.2017 intimated that CoD may be declared on successful trial run of EDWPCL at 90% PLF for 24 hours. Accordingly, GCC decided that the CoD of EDWPCL (10MW) be considered w.e.f. 00.00hrs. of 28.04.2017. 2. The rate of infirm Infirm power settlement methodology As per DERC directions dated 04.09.2017, power prior to will be as per CERC DSM regulation Infirm power settlement methodology will COD shall be from synchronization date 21.12.2015 be as per CERC DSM regulation from the settled as per the to 27.04.2017 from UI pool account date of synchronization i.e. 21.10.2015 (as provisions of maintained by SLDC.

COD.

The above issue was deliberated. During the discussion BYPL stated that their submissions vide letter dated 17.01.2018 should be considered, which are as under:- i) During synchronization to COD i.e. 21.10.2015 to 27.04.2017, EDWPCL has drawn (start up power) and has injected (infirm power), the power into the system. ii) Definition of infirm power

As per the clause 2(32) of CERC (Terms and Condition of Tariff) Regulation 2014, the definition of infirm power is reproduced below:

“Infirm power means electricity injected into the grid prior to the commercial operation of a unit or a block of the generating station in accordance with Central Electricity Regulatory Commission (Grant of Connectivity, Long-term Access and Medium Term Open Access in inter-state Transmission and related matters) Regulation 2009 as amended from time to time. iii) Definitions of Start up power a) As per clause 2(b) of CERC approved procedure for drawal of start up power dated 14.08.2014, the definition of Start up power is reproduced below:-

“Start up power, power required for running the Auxiliary equipment for commissioning activities of a new generating Station” b) Clause-2 of CERC (Grant of connectivity - Long Term Access and Medium Term Open Access in inter state Transmission and related matters) (Forth Amendment) Regulation-2014 is reproduced below:-

2 Amendment in regulation 8 of the Principal Regulation

a) Drawal of start up power shall not exceed 15 months prior to the expected date of first synchronization and 6 months after the date of first synchronization. b) Injection of infirm power shall not exceed six months from the date of first synchronization.

It is clear from the above that the infirm power is power injected and the start up power is power drawal by the generator before the COD. Further, the generator is allowed to inject / draw the infirm power / start up power for 6th months after synchronization. iv) Now, Delhi SLDC has decided to settle the net power i.e. Injection Minus drawal under DSM mechanism which is not agreeable to BYPL due to following : a) Based on the DERC directions vide order dated 10.06.2009, BYPL signed the PPA with EDWPCL on 29.10.09 for supply of 49% of 10MW capacity (later revised to 12MW) for 25 years. EDWPCL submitted the copy of signed PPA to DERC on 18.11.2009. b) Under the PPA signed between EDWPCL and BYPL, the treatment of Start up power is given as under:-

11.9 Payment for Start up power

11.9.1 The Seller shall be liable to pay, for the power and energy consumed for start-up of the Project and commissioning, to the distribution Licensee(s) in whose area the project is located or such other entity from whom such power / energy is sourced, at the then prevalent rates payable by such industrial consumers.

With respect of disagreement of BYPL in reference to point no. 5.4(4) of MoM of 18th GCC meeting, SLDC clarified that the DERC vide their letter dated 04.09.2017 has directed SLDC that the rate of infirm power prior to CoD shall be settled as per the provision of CERC DSM Regulations and in the past also for other power generators, the same process has been done for settlement of Infirm Power prior to CoD.

Considering the above, GCC reiterated its earlier decision of 18th GCC.

4. Implementation of DERC directions on EDWPCL:

As per the DERC letter no.F.9 (170)/DERC/DS/2016-17/5290/1091 dated 04.09.2017 regarding COD of EDWPCL Gazipur and adoption of Tariff, Point wise implementation strategy is proposed hereunder:

It is expected that the reactors at the above locations would be installed by the year 2020-21. GCC advised DTL and PGCIL to expedite the reactors installation as suggested by Standing Committee of CEA.

9.12 Efforts should be made to As per CPRI Study, it was concluded that due to variation of design islanding scheme generation in the Delhi Island envisaged earlier, the chances based on frequency sensing of survival of single island including the generation of Dadri relays so that in case of generating complex, Jhajjar, Bawana, BTPS and Pragati imminent Grid failure, generating stations would be more. electrical island can be formed. These electrical DTL representative informed that Revised Islanding scheme islands not only help in as per the NRPC /TCC recommendations is under maintaining essential implementation. The estimate has been prepared and is under services but would also help vetting stage. in faster restoration of Grid. Action : CEA, RPCs, CTU, GCC advised DTL to implement the revised islanding STUs, SLDCs and scheme at the earliest as it is meant for meeting the generators Time Frame : exigencies and to maintain power supply of critical six months installations at the time of Grid failure. 9.13. System Operation needs to Though Delhi SLDC is operated by DTL it has full autonomy 1 be entrusted to independent with regard to grid operation. Further it has separate ARR system operator. In approved by DERC for financial autonomy. Further a addition, SLDCs should be committee constituted for creation for SLDC as a separate reinforced for ring fences for company has already given its report to State Government. ensuring function autonomy. Decision is likely in line with the decision of Govt. of India on Action : Govt. of India, Independent System Operator (ISO). time frame : one year SLDC informed that action is being taken by State Government.

GCC noted. 9.15. The communication network The work has been completed. 2 should be strengthened by putting fiber optic GCC noted. communication system. Further, the communication network should be maintained properly to ensure reliability of data at Load Despatch Centers.

Claus RECOMMENDATIONS STATUS AS ON DATE e

9.20 For smooth operation of SCADA / Communication Department of SLDC informed that Grid system, it is absolutely the work has been completed. important that all the power generating and distribution GCC noted. stations are connected on a very reliable telecom network. i) A proper network may be built up preferably using MPLS (Multi Protocol Label Switching) which is simple, cost effective and reliable. In remote place where connectivity is a problem, the stations can use dedicated fiber cable from the nearest node. Since POWER GRID has its own fibber optic cables, practically covering all major nodes and power stations, a proper communication / IT network may be built using dedicated fibres to avoid any cyber attack on the power system.

While finalizing the power supply position, the following aspects have been considered:- i) Allocation of Discoms has been revised as per DERC order dated 27.03.2018. implemented from 01.04.2018. ii) Availability from Bawana CCGT has been considered as 525MW. iii) Availability from BTPS has been considered 360MW from April 2018 to July 2018 iv) Availability from GT has been considered as 125MW. v) Availability from Jhajjar is considered as 693MW (622MW at Delhi periphery).

From the above, it is seen that some of the Distribution Licensees are having shortages during some time slots especially BRPL having shortage during all months during peak period. MES has also shortage during August and Sept. 2018.

NDMC informed that they would meet the shortage by day ahead Power Exchange.

BRPL did not furnish any information in this regard.

GCC advised to all Discoms to prepare a contingency plan to meet the shortage.

B) High Voltage Operation of the Grid during Winter nights. i) This issue is regular agenda of Delhi OCC and being continuously discussed in OCC meeting from Oct-17 onwards. OCC has taken various steps to sort out the problem of high voltage conditions and injection of reactive drawal during winter nights. In the last OCC meeting, the following were deliberated:

A . Switching off the capacitors at all the Substations of Delhi, but during winter season proper monitoring of the same is yet to be put in place. B. Transformer taps optimization by DTL and DISCOM. DTL has changed Taps positions of most of the transformers at 220kV S/Stns C. Monitoring of all 400/220kV ICTs and taking actions wherein VAR flows are observed from 220kV to 400kV side. In this respect reactive energy accounts could also be monitored. D. Opening of lightly loaded transmission cables/ transmission lines keeping reliability in focus. E. Absorption of reactive power by generating units.

As decided in the last OCC Meeting no. of steps have been taken by SLDC, Delhi and Discoms to control the high voltage conditions and reactive power injection by Delhi system to the grid particularly during off peak time.

In the last meeting, all Stakeholders assured GCC that all efforts would be taken by them to minimize the injection of reactive power to the Grid especially during high voltage conditions. To control the high voltage issue, GCC had advised the following i)Generators to absorb reactive power during high voltage regime as per their capability curve. ii)DTL to form a Committee to look into high voltage issue including payment of Weekly Reactive Energy Charges bill to NRPC as Discom wise Weekly Reactive Accounts are managed by C&RA Department of DTL and Reactive Energy Charges at Regional level is paid by SLDC. iii)DTL for early commissioning of Reactors at various locations.

In spite of the all out efforts by SLDC, injection of reactive power could not be averted and Rs. 7.18 Crores have been levied on Delhi due to injection of reactive power to the Grid during high voltage conditions during the period 16.10.2017 to 01.04.2018.

It was explained that as a long term measure to control high Voltage, Standing Committee of CEA in its 39th Meeting held 29-30th May 2017 has suggested Bus Reactors in Delhi at various locations in Delhi as under:

In the last meeting, GCC advised all utilities to do the needful of bay extensions in line with the downstream setups. The Steering Committee was also advised to look into the issue of establishment of additional bays at GISs to avoid frequent extensions considering the future requirements. It was also advised that the addition of 100MVA Tx. at AIIMs be considered along with 33kV Bays extension to ensure reliability.

It was informed that Addition of new 220/33 kV, 100 MVA ICT at 220kV AIIMS can be possible only by 2021-22 as 220kV GIS bay is required to be added for which 220kV GIS building is required to be extended. However, 05 no. 33kV GIS bays are being added at AIIMS.

GCC reiterated its earlier decision.

3.8 Arbitrary scheduling by Delhi SLDC (TPDDL AGENDA)

There were many instances in past regarding arbitrary or forced scheduling of power by NRLDC. We write to NRLDC regarding force scheduling time to time. Delhi SLDC is very reluctant to change the scheduling to TP-DDL when there is force scheduling by NRLDC. After taking up the matter with NRLDC many times, NRLDC has responded that they scheduled the forced power ( RRAS, MTL etc.) to overdrawing entities under them i.e. Delhi, Further scheduling of this power to deviating DISCOM is the responsibility of Delhi SLDC. Delhi SLDC under current practice, schedule the power as per % of entitlement irrespective of OD or UD position.

With reference to above, Tata Power-DDL is requesting Delhi SLDC to adopt the scheduling guideline and align NRLDC. Force scheduled power by NRLDC will be scheduled to the DISCOM who is deviating from DSM regulation.

It is also observed that settlement value is added to TPDDL drawl. Settlement value is mis-leading during decision. Logic behind Settlement value need to be discussed with SLDC and Distribution of Settlement value should be as per suspected points. Example: - The value of 220kV MAHARANI BAGH was erroneous still settlement was given in Tata Power-DDL drawl about 70 MW.

In the last meeting GCC advised SLDC to take up a separate meeting with TPDDL to discuss and decide the issue.

GCC advised to call a separate meeting on 17.04.2018. Accordingly, a meeting was held on 17.04.2018. The MoM is enclosed as Annexure-3.

3.9 Position of Reliable Power Supply in Delhi through DTL Grid Substations (TPDDL AGENDA)

Maintaining supply of electricity is joint responsibility of DISCOMs and TRANSCO. Considering the importance of an efficiently built and operated transmission network, Hon’ble Commission has enacted the Delhi Electricity Regulatory Commission (State Grid Code) Regulations, 2008, referred to as the

“DGC Regulations, 2008”, which provides the standard procedures as well as the benchmarks which need to be met by the State Transmission Utility, which is DTL, while constructing and operating the transmission network.

As per Regulation 9.2 of the Delhi Grid Code Regulations, 2008, Transmission planning criteria of State Transmission system is reproduced below:

“The State Transmission System, as a general rule, shall be capable of withstanding and be secured against the following contingency outages without necessitating load shedding or rescheduling of generation during Steady State

Operation: (a) Outage of a D/C line of voltage above 66 kV and below 400 kV or, (b) Outage of a S/C line of voltage of 400kV and above or, (c) Outage of a single Interconnecting Transformer. Provided that the above contingencies shall be considered assuming a pre-contingency system depletion (planned outage) of another 220kV D/C line or 400kV S/C line in another corridor and not emanating from the same substation.”

Furthermore, the Regulation 9.6 of the “DGC Regulations, 2008”, Transmission planning criteria of State Transmission system states: “In all extra high voltage substations, suitable number and capacity of transformers shall be provided to have adequate redundancy required to maintain firm capacity at the substation”.

Explanation - for the purpose of Regulation 9.6, the term firm capacity shall mean the minimum transformation capacity available at the substation in case of outage of any one transformer.

These specific regulations lay down the criterion which needs to be met by DTL while operating the transmission network. However, the existing transmission network does not meet these criterions, it is the responsibility of DTL to augment the network and increase its capacity, to be able to meet these benchmarks. The Substations not confirming the said criteria for both lines and transformers are given vide Table-1 and Table-2.

DTL’s responses to the observations of TPDDL are also given in each issue. DTL further stated that some of the projects envisaged for providing reliability of the power supply to the areas including that of TPDDL are delayed due to reasons beyond the control of DTL. And, such issues are regularly discussed in the Steering Committee meeting and all DISCOMS are well informed. As such there was no deliberate change of targets of any of the projects and the delay is caused in each project were discussed in detail in SCMs.

The scheme is under Tendering Process. Commissioning is scheduled in 2020-21. Further the main source to feed the S/Stn. was from the proposed 400kV S/Stn. at IP (shifted from RPH Complex as the site falls in the Yamuna Flood Plain). The 400kV S/Stn at IP also could not be materialized. As such, the infeed was now envisaged through LILO of S/C Electric Lane –Park Street at Dev Nagar. Till the S/Stn. is commissioned (by the year 2020-21) BYPL and TPDDL are required to manage with the available source

The current updates in this regard be provided. 4. Issue relating DTL For execution of Connection Agreement, GCC advised to connection DTL wants Line differential relay at both Discoms to take up agreement for ends along with OFC cable connectivity. the matter in new 33/66KV This is possible where end to end new circuits Protection sub feeders from are being laid but where LILO of existing Committee. DTL grids circuits is being done and the other BYPL ends are far away, then it is very difficult to provide the OFC connectivity. Further as per the minutes of meeting of 7th Protection subcommittee held on 16.05.2017 circulated by DGM(T) Prot. & Metering, DTL vide letter No.F.DTL/F- 6/2017/DGM(Prot./Mtg.)/12 dt.22.05.2017, it is mentioned that “Discom shall install the Numerical Line Current Differential relay at both ends having feature of distance protection in case of communication failure for the lines which are less than or equal to 1 km and composite line (Overhead+Cable) irrespective of length with connectivity.” Thus as per this MOM where the line length is more than 1 KM and the line is not composite( i.e. only cable is there), the distance protection relay is sufficient to provide the desired protection. However, DTL (Commercial) does not permit in such cases also and stresses for providing Line Differential Relay along with OFC cable connectivity. This aspect may pleased be looked into It is to further submit that wherever there will be composite line and the length of the line is less than 1 KM, the OFC cable as well as Line Differential Relay shall be provided by BYPL.

matter was taken with NRPC team including Member Secretary, then after SLDC agreed to UI suspension and informed to SE(Comml.),NRPC on phone regarding SLDC agreement for suspension of UI during course of above trial cum part load operation. Then after, a confirmation email at 13:50hrs was also sent to SLDC by PPCL. Accordingly, after confirmation from SLDC side to NRPC team, the plant incharge was instructed to load the turbine at desired loads which were less than earlier given schedule. However, during preparation of UI Statement for week-29/FY 2017-18 a email dt. 21.12.2017 was also sent to SLDC (Energy Account Department), however the same has been ignored and UI account for the said week has been issued on 02.02.2018 wherein, PPS-III, Bawana has paid Rs. 14.02 Lakh on account of non consideration of UI suspension during trial run part load operation by NRPC team.

IPGCL/PPCL did not attend the meeting. As such, the issue could not be deliberated. However, SLDC has informed that the request for suspension of DSM charges has been accepted and the same would be implemented in the subsequent revisions of the respective DSM Account.

GCC Noted. b) TPDDL

1) Post facto Correction of Implemented schedule

TPDDL is controlling their drawl based on the real time schedule. The changes made in the schedule on post facto basis have led to imposition of huge penalties on TPDDL.

The real time scenario and deviations mentioned in final bill is very much different. TP- DDL is facing lot of difficulty in intra-day scheduling due to arbitrary adjustment in implemented schedule by energy account at the time of REA and DSM bill.

Some of the examples are: i) Tata Power-DDL experienced a lot of penalty due to non-communication of Delhi SLDC operation staff and energy accounting staff.

There are many instances where on account of grid security, Utilities have co- operated with each other with URS power, our own entitlement power sharing etc. during real time. However the information was not properly conveyed to energy accounting team, as result effort of real time power management goes into vein when the same is not reflected in respective book of accounts.

We have faced the same issue in DSM account of WEEK-33 and Week-37. We have communicated the same to energy account team vide letter and e-mail. ii) Methodology of adjustment in real time schedule

We have raise the issue of impropriate adjust distribution to energy account team through e- mail and letter. We are not agree with methodology of adjustment, However no action being taken from Delhi SLDC. We are requested to call a meeting with all stakeholders and finalised the procedure. The same was also not arranged by Delhi SLDC.

Few such observations are as follows:  When any generator generates power more than declared capacity i.e. SG is more than DC then the excess generation should be the sole part of DSM for that generator. However in current process, Delhi SLDC is distributing this excess generation within all entities.  Distribution of excess generation is in the ratio of schedule from ABT software which is incorrect methodology. It should be in ratio of % entitlement.  Any Discom should not be scheduled power more than his entitlement, except when asked for URS by concerned Discom.

iii) Scheduling of CCGT Bawana

We have faced a lot of issue in scheduling of CCGT Bawana on real time scheduling and post correction of the same in implemented. Share of Haryana and Punjab are deducted manually from total CCGT schedule in excel. We have faced forced scheduling of CCGT due to error in excel calculation. Many such instances were highlighted to energy account team through e-mail and letter.

The above issue of TPDDL was deliberated. SLDC informed that the current practise of providing 5 days time to stakeholders for providing clearance for issuance of DSM Accounts was adopted as per decision taken in MoM held on 12.01.2017 and 27.01.2017. The main reason for adopting the practice of providing 5 days to stakeholder was to minimize the errors and post facto revisions of DSM accounts. However, it has been observed that no fruitful results have achieved even after adopting the said practice. Further, the above said practice has resulted into unnecessary delays in issuance of DSM accounts. As such, SLDC requested to withdraw the above said practise.

Accordingly, GCC decided to withdraw the practise of providing 5 days time to stakeholders for clearance issuance of DSM Accounts.

Further, to settle the above TPDDL issues, GCC advised SLDC to call a separate meeting on 17.04.2018. Accordingly, a meeting was held on 17.04.2018. The MoM is enclosed as Annexure-2.

2) Issue of maintaining n-1 criteria of Transmission network under TPDDL’s area of jurisdiction

TPDDL informed that in May 2013, CEA had released the “Report on Transmission System Plan for Delhi” in which, certain projects were formulated keeping in mind the improvement of transmission System in Delhi and the execution of the same was entrusted upon DTL. However DTL failed to comply with the timelines as evident from below table.

Similarly, in Operation Co-ordination Committee dt. 28.06.2017 it was noted that in various 220kV DTL’s Substations, N-1 criteria was not being met.

S.No. Details of Sub-stations where n-1 criteria does not meet 1 220 kV Gopalpur 2 220 kV Shalimar bagh 3 220 kV Kanjhawala 4 220 kV Subzi Mandi 5 220 kV Wazirpur 6 220 kV Peeragarhi

From above stated facts, it is evident that Delhi Transco Ltd. neither has taken any step towards strengthening of the power system in Delhi as apparent from delayed timelines nor meets n-1 criteria at various 220kV S/Stations thus violating Clause 17 of Transmission License and Clause 9.2(a), 9.2(c) and 9.6 of Delhi Grid Code 2008.

It may be noted that SLDC had even intimated DTL about the existing constraints in the transmission network. Concerns were conveyed by GM (SLDC) to GM (Planning), DTL via letter dt. 12.08.2015 apprising about the existing bottlenecks in the transmission network and the system augmentation to be finished by 2017.

However, DTL failed to resolve the issues.

Looking into above facts, TPDDL requested to know the present status of these projects and the date when DTL submitted these Projects to DERC so that TPDDL can plan its ongoing & future projects accordingly.

DTL strongly objected the allegations of TPPDL that DTL failed to discharge the obligations of transmission utility. It was informed that DTL has been augmenting the transmission system depending upon the optimum transmission needs of the utilities; the following parameters substantiate the stand of DTL:

In the above background the status of project mentioned by TPDDL was explained as under:

S. Proposals Present status

For 66kV GIS, The bidders have quoted the exorbitantly high 220/66kV cost. The scheme is being reviewed and tender will be refloated. additional 2X160 However DTL is making all out efforts to install additional MVA Tx along 1 with 66kV GIS 160MVA Tr before next summer for which modality would be worked out in-coordination with TPDDL. Bays at 220kV Gopalpur The land required for establishment of the sub-station is not 220/33kV Punjabi available with DTL at present and matter regarding allocation of 2 Bagh Grid land is being taken up with DDA in coordination with power department GNCTD. The downstream feeding grids from 220kV Tikri Khurd are mainly DSIIDC grids to be established under deposit scheme. However, due to non-picking up of load in the area, the scheme 220/33kV 3 was delayed and likely to be completed in year 2021-22 as Tikrikhurd Grid decided in the SCM held on 29.06.2017. As such Tikri Khurd has been shifted to the last phase of the Business Plan i.e. in 2021-22.

DTL Board has already approved the scheme on 28.03.2018. As 220/33kV Timarpur already intimated the NIT is expected to be floated by 30.09.2018 4 (Earlier with expected date of award by 31.03.2019 with the completion Chandrawal) schedule of 18 months. All possible efforts are being made to make the S/stn available by 30.09.2020. 5 Alternate Feed For The 220kV Subzi Mandi Grid S/Stn. is located in very congested Subzimandi area. Due to lack of space there is no 220kV bus in the S/Stn. Substation The 220/33kV Tx. are directly fed through 220kV Gopalpur- Subzi Mandi Ckt 1 & 2. To ensure 2nd feed of Subzi Mandi and addition of 100MVA Tr. the existing 220kV AIS needs to be converted into 220kV GIS, which is not possible without affecting the power supply of 220kV Grid S/Stn. On 06.08.2015 a joint site visit along with TPDDL was also carried out to explore the possibility of conversion of the 220kV AIS to 220kV GIS without affecting the power supply of the areas fed from 220kV Subzi Mandi S/Stn. The possibility worked out was that the existing 33/11kV, 16MVA Tx. 1 & 2 should be dismantled to make space for 220kV GIS which was turned down by TPDDL due to lack of back feeding arrangement of the areas fed from these 33/11kV 16MVA Txs.

As such, it would only be possible after establishment of the 220kV Timarpur S/Stn. which is proposed to be established in nearby area, the entire load of 220kV Subzi Mandi Grid S/Stn. can be shifted to the proposed 220kV Timar Pur at 33 kV level and the 220kV GIS conversion can be taken up to provide 2nd 220kV feeders from the upcoming Dev Nagar S/Stn. and addition of 100MVA Tr.

Present status S.N Proposals 220/66kV SGTN The sub-station package has been awarded on 26.06.2018 with 6 Grid completion period of 18 months. 7 220/33KV GIS at L&DO, Ministry of Urban Development, Govt. of India has Karol bagh allocated land to Govt. of Delhi for establishment of 220kV S/Stn (Earlier at Dev Nagar by DTL and 33kV S/Stn. by BYPL. The land is not Karampura) free as DJB water pipeline is passing through the plot. L&DO has been requested to allot land for shifting of DJB services and office situated in this place. However, BOD of DTL has approved the scheme in its meeting held on 26.09.2017, The scheme is under tendering stage and S/stn is expected by 2020-21. Till the time BYPL and TPDDL are required to manage with the available sources.

Plan to meet n-1 contingency in the sub stations mentioned by TPDDL:

Details of Sub-stations where n-1 S.No. criteria does not meet Plan to meet n-1 contingency 1 220 kV Gopalpur Two Tx. of 220/66kV, 160MVA capacity along with 66kV GIS are planned. 66kV GIS is delayed as reasons mentioned above and is likely to be commissioned by 31.12.19. By next Summer, 160MVA Tx. is proposed to be installed and is to be connected to 66kV Bus through 66kV cable (TPDDL would be requested to supply 1km 1000 sq. mm. 66kV cables on loan basis) till 66kV GIS is established. 2 220 kV Shalimar Bagh Additional 220/66kV, 100MVA Tx. is being installed by Dec-18. Additional 220/33kV, 100MVA Tx. is also being planned. 3 220 kV Kanjhawala Additional 160MVA Tx. is proposed by 31.05.19. 4 220 kV Subzi Mandi As already mentioned above. 5 220 kV Wazirpur Additional 100MVA Tx. is proposed to be installed by 2020-21 for which 220kV GIS bay is to be extended. Due to space constraints in the 220kV GIS Building, OEM has been requested to explore the possibility for extension of the 220kV GIS bay. 6 220 kV Peeragarhi Due to space constraints additional Tx. cannot be possible as decided in the SCM held on 30.10.2017 and reiterated in SCM held on 17.01.2018. The load would be eased after the commissioning of 220/66kV Budella S/Stn. for which order has been placed on 28.06.18 with the commissioning schedule of 18 months.

It was also mentioned that without assessing the factual requirement, the addition of transmission network would be resulting into high transmission tariff thereby increase in consumer tariff which is not in the interest of public. DTL again reiterated that some of the projects envisaged for providing reliability of the power supply to the areas including that

of TPDDL are delayed due to reasons beyond the control of DTL. And, such issues are regularly discussed in the Steering Committee meeting and all DISCOMS are well informed. It was advised that TPDDL should also optimise the use of available resources for economic operation of the system as it was observed that the load of number of grid S/stn like 220kV Kanjhawalan, DSIDC Bawana, Mundka etc. picked up to the present level after a long period of their commissioning. Further, the load at 220kV Rohini-II at present is 92MW only against the capacity of 272MW.

GCC advised all the utilities to co-ordinately plan the system for ensuring reliable and economic operation of the system.

7 HOSTING OF NEXT MEETING OF GCC

In the 18th GCC meeting, representative of NDMC had expressed their inability to host 19th GCC meeting. However, he assured that NDMC could host 20th meeting of GCC. Accordingly, GCC decided that next GCC meeting will be hosted by NDMC.
