8 5 TN IL&FS Pondy TELANGANA Reconciliation of Open Access disbursements The details of disbursements of STU & SLDC Open Access for the period from Aug 2015 to Nov 2015 are enclosed in Annexure-IV. The same has already been sent to all the concerned SLDCs/STUs/CTU and others on a monthly basis for reconciliation. Reconciliation of the same was done by only KPTCL. Since no comments were received from others the disbursement to be treated as reconciled. However, members may note that it is compulsory to return the signed copies of the statements. 6. Delay in SEM data transfer: Some of the entities are not sending SEM data within time in line with IEGC Clause , Statement of delay in SEM data transmission from various sites is enclosed in Annexure-V. Constituents are once again requested for compliance. The status of SEM data receipt as on 17:00 hrs of Monday and 12:00hrs of Tuesday is available in the SRLDC website under the menu Commercial>SEM data receipt status. All stations and SLDCs may monitor this information on the web and ensure the timely transmission of SEM data to SRLDC. 7. Time drift correction Though the matter was taken up in the past Commercial Sub-Committee meetings, still many stations of CTU/STUs are not adhering. The status of receipt of time drift / correction report is enclosed at Annexure-VI. 8. Non-intimation of the reasons for Under-recording In the event of under-recording of the SEMs, SRLDC has been intimating to the Regional entities. However no feed back is being received by SRLDC. All entities are requested that CT/PT inputs to the SEM are monitored and maintained. All events of under-recording shall be immediately intimated with the reasons for under recording along with the remedial actions taken 9. Low CT Ratio to be adopted for computation of Auxiliary consumption through ST/TT/SUT/Line etc drawl of start-up power through GT It is observed that some of the stations have adopted higher CT ratios for Auxiliary consumption (through ST/TT/SUT/Line) which would be normally in the range of 5-10% of the Unit capacity. Similarly, during the period of drawl of Startup power, some of the stations have been adopting high CT ratio of such as 3000/1 or 2000/1 which are Page 3 of 5

9 generally required for after commissioning of the Unit. As the quantum of power drawn during startup and Unit outage is very low, adopting lower CT ratio would result in better accuracy of recording. Regional Entities may check if the adopted CT ratios were the least available ones, if required take remedial action and intimate. Where it is not possible to do so, the Committee may look into the matter and advise. 10. Application of loss during non-availability of SEM data As of now, in the event of non-availability of SEM data or under-recording at one end of the line, other end data is being used after application of loss of 1% for 400kV lines and 2% for 220/230kV lines. It is proposed to discontinue the practice of applying loss in the energy accounting as it is the responsibility of the regional entity to maintain the SEMs and ensure timely receipt of SEM data at SRLDC Installation of Standby SEMs on LV side of GT-7 and TT-4 at Ramagundam STPS-stage III Injection of RSTPS-stage I& II is being computed by subtracting the injection of RSTPS stage-iii from the total of out going feeders. ie readings of GT-7 and TT-4 are subtracted from the outgoing feeders (total injection of the whole station). (a) Total injection of RSTPS = sum of all out going Lines and ICTs (b) Injection by RSTPS Stage -III = (GT-7) - (ST-4) (c) Injection of RSTPS (unit 1 to 6) = (a) (b) In the event of failure /under-recording of the SEMs on GT-7 and ST-4, there is no fall back arrangement. Therefore, it is proposed to arrange fall back arrangement by installing stand by SEMs on LV side of the GT-7 and ST-4. Upon approval by the Committee, necessary SEMs may be installed. 12. PoC Data for Q1 of (from April 16 to June 16) As per prevailing CERC orders PoC computations are being carried out by NLDC on quarterly basis. Data for Q1 ( ) may also be furnished by 15/01/2016 as per NLDC s letter dt. 01/01/2016 (enclosed in Annexure VII). As STOA approvals are issued three months in advance, it is essential that the computations are completed well in advance. All the DICs to furnish (1) The technical details of new transmission elements, generating units which are expected to commence commercial operation (2) Yearly Transmission charges (3) Node wise MW/MVAR Injection and Drawl and Page 4 of 5

10 (4) Forecast generation and demand data. All DICs are requested furnish the full data required for computations at least by two quarters in advance without waiting for reminders from NLDC/SRLDC. 13.

80 TAMIL NADU TRANSMISSION CORPORATION LIMITED (Subsidiary of TNEB Ltd) From Er. G.Venkatesan, B.E., Superintending Engineer/LD&GO, SLDC Block, Chennai To The Superintending Engineer, Southern Regional Power Committee, No.29, Race Course Cross Road, Bangalore Lr. No. SE/LD&GO/EE/G/AEE2/AE2/F. CCM /D /2015, Dt Sub: Points to be included in the Agenda of the ensuing 30 th Commercial Sub- Committee Meeting Regarding. Ref: SRPC/SE-I/30 CC/2015, dt As requested vide letter cited in the reference, the following points are furnished to include in the Agenda for the 30 th Meeting of the Commercial Sub-Committee of SRPC: 1. Transmission charges for the Long Outage Generating Unit / Not-able to maintain the approved Injection quantum by Generator for long time has to be paid by the Generators itself: As per CERC (Sharing of Transmission Charges and Losses) (Third Amendment) Regulations, 2015, the Point of Connection (PoC) injection charges have been merged into PoC withdrawal charges in respect of withdrawal Designated ISTS Consumers (DIC). In this regard the PoC slab rate for the DIC includes both withdrawal as well as injection charges. The DIC has to pay the transmission charges for the Approved withdrawal quantum specified in the RTA. The Approved withdrawal of DIC is calculated based on their ex-bus share from all the ISGS stations for the installed capacity after declaration of CoD. The above Approved withdrawal also includes the ex-bus share from the ISGS stations under AOH / Generator not generating up to the approved injection quantum for the installed capacity for the month. Hence the DIC has to pay the transmission charges for not withdrawing any quantum from the ISGS stations under AOH/Generator not generating up to the approved injection quantum for the month. In Southern Region, KKNPP Unit-1 is taken out of bar for AOH during the month end of June 2015 for a period of 60 days, but still now the unit has not turned back to its generation. Due to the above long shutdown of KKNPP Unit-1, Tamil Nadu had paid an amount of Rs.47.04

81 crores as transmission charges for withdrawal quantum of MW per month as ex-bus share from KKNPP Unit-1 from July 2015 to November But for the above five months, the Tamil Nadu had paid the transmission charges for not utilizing the energy from KKNPP instead for blocking the corridor alone. Hence the Tamil Nadu request is that the whenever a Generating unit is under long shutdown, the transmission charges for that period has to be paid by the Generators alone and it should not be passed on to the DIC/Beneficiaries bills. Likewise, the ISGS stations like NTECL, NLC TS2 Exp, NTPL has not maintaining the approved injection quantum for long time, the transmission charges for the Generating stations not maintaining the approved injection quantum for long time also has to be paid by the respective Generators alone and the same should not be passed on to the DIC/Beneficiaries bills. 2. Energy Transactions between Western Region and Southern Region: It is hereby intimated that an amount of Rs. 98,64,551/- have been received from MSEB towards amount payable by MSEB to TNEB towards the energy transaction for the period from August 1999 to December The pending net arrears between SR and WR Constituents for long period are listed below. Amount Payable by TNEB to Chattisgarh Rs. (-) 92,77,878 Amount Receivable by TNEB from MPSEB Rs. 1,17,17,268 Nett amount Receivable from Western Region (MPSEB) Rs. 24,39,390 It is requested that the above may be taken up with WRPC and its constituent MPSEB for early settlement for TN receivable amount. Yours faithfully, Sdxxx( ) Superintending Engineer/LD&GO

85 S R P C, S E C R E T A R I A T SCADA Vs SEM-mismatch

86 Possible Reasons For Deviations The Accuracy Class Of SCADA Is 0.5S, The Accuracy Class Of The Interface Meters Data Is 0.2s. Scan Rate of parameters SEM Higher Scan Rate

87 Errors at the source- SCADA RTU failure / database corruption in SAS / RTU PT fuse failure Faulty transducers Communication failure SEM Time drifting of Interface Meters clock PT fuse failure

88 Other Factors Difference in combination of drawal points considered. Non-availability of telemetry at all points

89 Way Forward Improving communication for reliable telemetry- achieve redundant paths with optical fiber at all data points Providing RTUs/telemetry facilities at all locations Philosophy of manual substitution in case of telemetry failure Philosophy of selection of data points for calculation of drawal Quick rectification of Interface Meter errors

113 Sharing of Transmission Charges 10. The Commission vide RoP of the hearing held on directed the petitioner to submit information regarding the utilization of the transmission assets for which tariff has been sought in the present petition. The petitioner vide affidavit dated has submitted that the North-Eastern Region of the country has a very large hydro generation potential of the order of 50,000 MW apart from approximately 4500 MW in the State of Sikkim. In addition, about 5000 MW of hydro generation was envisaged to be developed in Bhutan and power from such generation would be consumed in India. This huge quantum of hydro potential was planned to be developed in a phased manner to meet the growing energy requirement in the country in the long run. To evacuate such a huge quantum of power, the petitioner as the Central Transmission Utility planned and executed the transmission systems associated with North East-Northern / Western Interconnector-I Project. The petitioner has submitted that the transmission lines covered under the transmission systems had to traverse through the difficult terrains of NER and ER and the limited corridor available in Chicken Neck area which is a narrow patch of land measuring 22 km in width and 18 km in length near Siliguri having borders of Nepal on one side and Bangladesh on the other side and the area is largely habitated. The petitioner has submitted that all transmission lines, railway lines, gas pipe-lines, telecommunication lines, etc., from NER to the other parts of the country have to pass through the Chicken Neck area and therefore, the petitioner keeping in view the requirement of evacuation of power over a long distance with optimal utilization of RoW available in that area and the limitation of longer AC system due to requirement of reactive compensation and other economic constraints, planned to Order in Petition No. 67/TT/2015 Page 9 of 26

114 construct 5-6 high capacity HVDC power transmission corridors connecting NER Grid with National Grid. Regarding capacity of transmission assets, the petitioner vide affidavit dated has submitted that keeping in view the phased generation addition, HVDC corridor was planned for 6000 MW while the terminal stations were planned in modules of 3000 MW. The petitioner has submitted that the sending end HVDC terminal stations of 3000 MW at Biswanath Chariali and 3,000 MW at Alipurduar (under "Transmission System for development of pooling station in Northern part of West Bengal and transfer of power from Bhutan to NR / WR") are under implementation and the receiving end HVDC terminal stations would be of ultimate capacity 6000 MW, to be installed in two stages at Agra from where power can be transferred to deficit Northern/Western Regions. 11. Regarding the basis of planning of transmission systems, the petitioner vide affidavit dated has submitted the following:- (a) Keeping in view the long term perspective it was desirable to implement the subject transmission systems as a transmission infrastructure which would facilitate the transfer of power even as the major hydel projects get completed. The Scheme was deliberated in various Standing Committee Meetings (SCMs) on Power System Planning and Regional Power Committee (RPC) Meetings in Northern Region, Eastern Region, Western Region and North-Eastern Regions and based on the deliberations and discussion in these forums, the transmission systems have been planned as a Regional System Strengthening Scheme. In the meeting taken by the Secretary (Power), Government of India on , it Order in Petition No. 67/TT/2015 Page 10 of 26

115 was decided to plan transmission corridors in the Chicken Neck Area to meet the evacuation requirement for next 10 to 15 years. (b) The NER Grid is presently connected to the rest of the National Grid through series of AC lines passing through Bongaigaon Sub-station. NER Grid has been connected with rest of the National Grid through radial AC lines and on account of transmission constraints on AC lines, such types of radial connections are not desirable from the point of view of Grid Stability and Security. Moreover, tripping of inter-connecting lines with NER also leads to grid disturbance. (c) Biswanath Chariali - Agra HVDC line will help in strengthening links of rest of the National Grid to NER Grid. The petitioner has further submitted that during monsoon, with high hydro generation in NER, North Bengal and Bhutan, loading of 400 kv Binaguri - Purnea 2 x D/C and Purnea - Muzaffarpur D/C remains high. Therefore, Biswanath Chariali - Agra HVDC line will provide a parallel path and relieve loading of these lines. (d) The Teesta-lll generating station is expected to be commissioned in , while Rangpo-Kishanganj D/C line is expected to be delayed. The HVDC line would help in evacuation of hydro power of Sikkim, even in the absence of Rangpo-Kishanganj line. 12. Further, the petitioner has submitted that the HVDC assets of the transmission systems for which tariff have been sought in the present petition are for benefit of the entire country on account of the following reasons:- Order in Petition No. 67/TT/2015 Page 11 of 26

116 (a) The HVDC lines will relieve the load in the intervening AC network. The petitioner has cited the examples of Mundra-Mohindergarh and Talcher-Kolar HVDC lines which have been modulated to control flow through AC lines. According to the petitioner, Mundra-Mohindergarh HVDC lines are relieving the load on 765 kv Gwalior-Agra lines. (b) HVDC lines will help in Voltage control, as power flow through parallel AC line can be increased/ decreased as per the requirement. (c) systems. HVDC lines will enhance the power transfer capability of the transmission (d) HVDC lines will accommodate renewable-variation and intermittency can be taken care of. 13. In response to the Commission s query through letter dated regarding the planning of the subject transmission system, CEA has submitted the following vide its letters dated and : (i) The capacity of ±800 kv HVDC bipole as agreed in the various standing committee meetings on power system planning (SCMPSP) of Northern, Western and North Eastern regions and TCC/RPC meeting of North Eastern Region is 6000 MW with 3000 MW rectifier module at Biswanath Chaiyali. (ii) As desired, copies of the minutes / extracts of the minutes of the meetings in which the above scheme was discussed and agreed are enclosed as below: a) 20 th SCMPSP of Northern region held at Nanital, Uttranchal on b) 26 th SCMPSP of Western Region held on at WRPC, Mumbai. c) 2 nd SCMPSP of North-Eastern Region held on at Guwahati. d) 25 th SCMSP of Northern region held on at NRPC, New Delhi. e) 6 th TCC & 6 th NERPC meeting held on 7 th 8 th Aug at Gurgaon. Order in Petition No. 67/TT/2015 Page 12 of 26

117 (iii) The HVDC bipole line was agreed as a part of associated transmission system/inter-regional system for Lower Subansiri (8x250 MW) and Kameng (4x150 MW) HEPs. As per the information available in CEA, the work on Lower Subansiri HEPs is held up since Dec., 2011 due to agitation by anti dam activists and the latest commissioning schedule is The Kameng project is likely to be commissioned by Until these generation projects are commissioned, HVDC module at Biswanath Chariali would remain unutilized. 14. CEA vide its letter dated has submitted the original and revised/latest schedules of commissioning of these HEPs as under:- Sl. No. HEP Original Schedule Revised/Latest Schedule 1. Kameng Lower Subansiri Work held up since December, Punatsangchhu-I Beyond Punatsangchhu-II Beyond Mangdechhu Beyond CEA vide letter dated has stated that HEPs have been considerably delayed and in the absence of these generation projects, the HVDC interconnector-i would not be utilized in the manner it was planned. CEA has submitted that the implementation of a transmission project may not be possible to be delayed beyond a certain time on account of contractual obligations of the petitioner with various EPC contractors. CEA has further stated that as recorded in the minutes of the 14th meeting of NERPC held on , the petitioner had slowed down the implementation of the transmission systems. Order in Petition No. 67/TT/2015 Page 13 of 26

118 15. The Commission vide letter dated sought the views of POSOCO with regard to the utilization of ± 800 kv Biswanath Chariali- Agra HVDC line in the backdrop of partial commissioning/non-commissioning of associated generation projects. POSOCO vide letter dated has submitted that one pole of the HVDC Biswanath Chariali-Alipurduar-Agra line was expected to be commissioned in September, 2015 would be the first Multi-terminal HVDC with terminals located at Biswanath Chariali (NER), Agra (NR) and Alipurduar (ER) and would be operating at ±800 kv. Considering the seasonality of hydro generation, it would also be the 1 st HVDC bipole having flows in either direction depending on the season and would provide the flexibility and function as a pseudo phase-shifter. A report dated 17 th September, 2015 has been prepared by POSOCO for the operational modalities of HVDC BNC-Agra which has been circulated to RLDCs/RPCs/ CTU/CEA/ POWERGRID. POSOCCO has submitted that generation and load of NER is seasonal and so is the flow on ER-NER corridor. In order to cater to the seasonal changes in the load, generation and line flows, flexible transmission in the form of HVDC is essential. Any new element added to the network is adding to the reliability of the system and is being utilised by the system operator to the maximum extent. POSOCO has emphasised that the transmission assets are normally planned for a life of 35 years and the advantages need to be assessed over the entire life cycle of the assets rather than the initial years. POSOCO has submitted that the maximum power order on this HVDC shall be initially restricted to maximum 1000 MW depending upon real time conditions till the time 400 kv Ranganadi-Balipara D/C is looped in looped out (LILO) at 400 kv BNC Sub-station. POSOCO has also submitted that low frequency oscillations have been observed few Order in Petition No. 67/TT/2015 Page 14 of 26

119 times in NER. HVDCs have controllers such as Power Oscillation Damping (POD) which could be tuned to mitigate such oscillations in inter-area mode. Similarly, the frequency controllers at BNC should also help in operation of NER system, if it were to get islanded due to any reasons. POSOCO has submitted that the area around Binaguri is prone to lightning strikes which have led to multiple outages of 400/220 kv circuits from Binaguri many times and leads to evacuation problem of hydro generation in NER during high hydro conditions and curtailment of NER drawl from the grid. With the commissioning of HVDC BNC-Agra, it is expected that the outages (planned/emergency/forced) in the underlying 400 / 220 kv network would not impact the evacuation of hydro generation or drawl of NER. 16. Assam Power Distribution Company Limited (APDCL), one of the respondents, in its reply filed vide affidavit dated has submitted that the subject HVDC network along with AC portion was conceived as the ATS of Subansiri HEP (200 MW) of NHPC and Kameng HEP (600 MW) of NEEPCO at 1 st TCC & 2 nd Power Committee Meeting of NERPC on 28/ in which it was decided that NER beneficiaries would share the transmission charges and beneficiaries outside NER and having allocation from NER projects would also share transmission charges of AC portion. APDCL has also submitted that there shall be mismatch of commissioning generation station with respective ATS and requested the Commission to look into the matter and not to burden the beneficiaries like Assam for failure on the part of generating station in commissioning the units. APDCL has further submitted that a number of hydro projects are coming up in NER and at present NER has no permanent allocation of power from Order in Petition No. 67/TT/2015 Page 15 of 26

120 sources located in other regions. During the hydro season, the region is always in surplus and the seasonal shortfall is nominal which is being maintained through existing AC network. APDCL has submitted that under the present funding system, the bidirectional flow seems to be not necessary immediately. 17. The petitioner in its rejoinder filed vide affidavit dated has submitted that the subject transmission systems were not built only for evacuation of power from Kameng HEP of NEEPCO and Subansiri HEP of NHPC. The original plan was conceived in the year In this regard, several meetings were held in the Ministry of Power, Government of India at the Secretary and Joint Secretary levels during the period In the meeting taken by the Joint Secretary, Ministry of Power in October 2003, CEA suggested that for connecting NER with rest of India, the only option would be to construct the HVDC bipole from NER to NR with the capacity of the order of 3500 to 4000 MW. Accordingly, the subject transmission system was planned as a strengthening scheme in order to provide for important transmission service connecting the NE Region to the Northern and Western Regions. Therefore, the petitioner is entitled for timely grant of tariff. The petitioner has submitted that there is no mismatch between commissioning of generating stations and the subject transmission assets as generators in NER (Lower Subansiri and Kameng) had earlier proposed their commissioning schedule as March, 2010 and December, 2010 respectively. However, the commissioning schedule has been revised by generation developers from time to time. The petitioner has submitted that after commissioning of this link, power up to 900 MW in both the directions is being transferred over this link and thus, the need for Order in Petition No. 67/TT/2015 Page 16 of 26

121 bidirectional flow of power has been proved in just few days of the operation of the link. The petitioner has further submitted that that the NER NR / WR Interconnector I, shall provide the following benefits to the DICs:- a) The link provides flexibility of power transfer in the seasonal varied hydro power generation of NER and would function as a pseudo phase-shifter. b) Surplus power to the extent of 1500 MW can be exported / imported between NER and other regions. c) Power can be imported by NER during low hydro season. d) The link would enhance the power transfer capacity between ER and NR. With the commissioning of many generation projects coming up in NER, Bhutan and Sikkim in next 2-3 years, power flow over this link shall increase. e) This link would provide stability to interconnection of NER with National Grid. f) This shall reduce maximum angle spread across the NER NR grid by degree. 18. The petitioner has submitted that the precise issue being raised by APDCL was considered in the Report of Sub-Committee of CAC on Congestion chaired by Shri R.V. Shahi, Ex-Secretary (Power) which included Members from CEA, CERC, GRIDCO, APTRANSCO, POSOCO, IIT, MERC, APP in June, The following has been recorded in the said meeting:- (xix) NER States have huge Hydro potential. It would be wrong to assume that all projects will be developed in the same time frame. It would be also be a wrong strategy to develop transmission systems adequate enough only for the projects already under implementation. Long term planning would require development of transmission systems in a manner that they are normally underutilized in the initial years but later utilized well. Order in Petition No. 67/TT/2015 Page 17 of 26

122 19. With specific reference to the submission of APDCL for sharing of transmission charges of the subject transmission systems, the petitioner has submitted that as per the decisions taken in the 1 st TCC and 2 nd Power Committee Meeting of NERPC held on and , Assam supported commissioning of strong transmission corridor from NER to other regions and agreed to share/pay the cost of transmission system as per CERC norms. Therefore, APDCL cannot renege on its commitment at this stage. The petitioner has prayed that the sharing of transmission charges shall be in accordance with the provisions of the Sharing Regulations, as amended from time to time. 20. During the hearing on , the representative of the petitioner submitted that based on various discussions and deliberations in various meetings taken in Ministry of Power (MoP) during wherein a need was felt to establish a high capacity transmission infrastructure to interconnect North Eastern Region (NER) to other regions of the country. This link is the backbone of National Grid. He submitted that based on the master plan prepared by CEA in March, 2006, a Detailed Project Report (DPR) for high capacity HVDC corridor including corridors in Chicken Neck area was submitted to Ministry of Power in He further submitted that the Planning Commission (Project Appraisal and Management Division) initiated Public Investment Board (PIB) on 7 th April, 2008; however, after the petitioner was notified as a Navratna company, PIB clearance was no longer required. He submitted that the Investment Approval was obtained from the Board of Directors of the petitioner on with an estimated cost of ` 11, crore. Further, the Board of Directors of the petitioner Order in Petition No. 67/TT/2015 Page 18 of 26

123 has vide letter dated approved Revised Cost Estimate (RCE) of ` crore including Interest During Construction (IDC) of ` crore. He submitted that the 1500 MW module of ±800 kv Biswanath Chariali-Agra HVDC system has been commissioned and power up to 900 MW in both directions has been transferred over this link. He also submitted that presently NER is connected to rest of the country vide AC system emanating from 400 kv Bongaigaon Sub-station and in case of major contingency, the NER will be cut out of the entire country. With the Commissioning of the HVDC system, NER would be able to draw reliable power from National Grid irrespective of major contingency in AC interconnections. He prayed that as per proviso (i) of Regulation 7(7) of the 2014 Tariff Regulations, the Commission may grant tariff up to 90% of the AFC of the transmission system or element thereof for the purpose of inclusion in POC charges in accordance with the Sharing Regulations. 21. During the hearing, the representative of POSOCO stated that the link was tested for 1500 MW from BNC to Agra and for 1000 MW from Agra to BNC on All the HVDCs existing in the Country prior to commissioning of this link were associated with thermal projects, but this link is associated with hydro projects. He also stated that in the absence of Binaguri Purnea D/C line since last 2 weeks, TTC /ATC of NER NR is not affected only because this link is available. Representative of Assam stated that since generation projects have not come up, beneficiaries should not be burdened with transmission charges for the link. On a query of the Commission whether the link is carrying any power, representative of petitioner replied that the link is currently carrying 900 MW from Agra to BNC. Order in Petition No. 67/TT/2015 Page 19 of 26

124 22. We have considered submissions of the petitioner and respondents. Central Electricity Regulatory Commission (Sharing of Transmission Charges) (3rd Amendment) Regulations, 2015 provides the guidelines for sharing of HVDC charges as under: Treatment of HVDC: Flow on HVDC systems is regulated by power order and remains constant for marginal change in load or generation. Hence, marginal participation (MP) of HVDC systems is zero. Since the HVDC systems were specifically set up for transfer of bulk power to specific Region, the DICs of the Region shall share the cost of HVDC systems. HVDC system also helps in controlling voltages and power flow in inter-regional lines and some benefits accrue to all DICs by virtue of HVDC system. Accordingly, 10 % of the MTC of these systems be recovered through Reliability Support Charges. The balance amount shall be payable by Withdrawal DICs of the Region in proportion to their Approved Withdrawal. In case of Injection DICs having Long Term Access to target region, it shall be payable in proportion to their Approved Injection. Where transmission charges for any HVDC system line are to be partly borne by a DIC (injecting DIC or withdrawal DIC, as the case may be) under a PPA or any other arrangement, transmission charges in proportion to the share of capacity in accordance with PPA or other arrangement shall be borne by such DIC and the charges for balance capacity shall be borne by the remaining DICs by scaling up of YTC of the AC system included in the PoC The SoR of the 3 rd Amendment to the Sharing Regulations, 2010, provides as under: For any new HVDC line, the Commission shall decide the methodology through an order. However, the above principle of sharing of transmission charges of HVDC lines may be reviewed based on the national transmission planning, if certain HVDC systems are planned to cater to multiple needs i.e. evacuation or reliability or Renewable integration or change in the benefits derived by the stakeholders. 24. Keeping in view the above provisions of Sharing Regulations, we proceed to decide the proposed methodology for sharing of transmission charges for the HVDC link (Asset-I). 25. Government of India mooted a proposal for development of hydro projects with a capacity of MW and accordingly, MW Hydro Electric Initiative was Order in Petition No. 67/TT/2015 Page 20 of 26

125 launched in May 2003 by the then Hon ble Prime Minister of India. About MW of power was planned to be evacuated from NER / Sikkim and Bhutan. The transmission system for all the generation projects was to traverse through Chicken Neck area having a length of 18 km and width of 22 km and would require about 1.5 km wide transmission corridor to evacuate the quantum of power. In a meeting taken by Jt. Secretary (Hydro), Ministry of Power on , it was decided that the hybrid system of HVDC and AC was the desirable option for evacuation of MW of power from NER by the end of 12 th plan. In the meeting taken by Secretary (Power) on , it was decided that corresponding to the ultimate capacity of hydro projects in NER, the evacuation system would require transmission corridors passing through the Chicken Neck area. During the meeting taken by Secretary (Power) on , it was decided that for security, reliability as well as for reservation of right of way, it would be desirable to go ahead with the building of transmission corridors in the Chicken Neck area. In another meeting taken by Secretary (Power) on , the phased development of NER / Sikkim and Bhutan projects was deliberated and it was decided that the transmission system should be developed for phased development of generation at the rate of 2000 MW each during , and respectively. Central Electricity Authority submitted a comprehensive note to Ministry of Power on on the transmission system for evacuation of power for major generation projects in the North Eastern Region along with power from projects coming in Sikkim and Bhutan during the 11 th plan and 12 th plan period. CEA in the said note has suggested that the option of hybrid network of HVDC and high capacity 400 kv line has been found to be most suitable from cost, corridor, operational and phased Order in Petition No. 67/TT/2015 Page 21 of 26

126 development consideration. Further, CEA has also stated that as the transmission distance from NER / WR is quite long i.e to 2500 km, the requirement of keeping the losses within reasonable and cost effective limits suggests strongly in favour of adopting as high a HVDC transmission voltage as possible. The planning of the transmission system as stated by CEA in the Note to the Ministry of Power is as under: - The first 800kV HVDC bi-pole line has been planned from a pooling substation at Bishwanath Chariyali in North-eastern Region to Agra in Northern region. This is being programmed for commissioning matching with Subansiri Lower HEP in The transmission line would be for 6000 MW capacity and HVDC terminal capacity would be 3000 MW between Bishwanath Chariyali and Agra. In the second phase, for transmission of power from hydro projects at Sikkim and Bhutan pooled at Sliguri, another 3000 MW terminal modules would be added between Siliguri and Agra. Accordingly, CEA suggested for implementation of the transmission system under a scheme titled Inter-regional transmission system for power export from NER to NR / WR. CEA further suggested to adopt national approach for development of the transmission system in which the beneficiaries outside NER would share the transmission charges of identified transmission system based on the power allocation from the NER Hydro projects. In a meeting dated taken by Secretary (Power), it was decided that the transmission system from NER to NR / WR would be required and the proposal for Public Investment Board (PIB) clearance for the project be initiated. Accordingly, a note for Public Investment Board was initiated by the Planning Commission (Project Appraisal and Management Division) on 7 th April, 2008 in which the project was found suitable and optimal considering the right of way. In the mean time, the petitioner was notified as a Navratna company and PIB clearance was no longer required. Investment approval was obtained from the Board of Directors of the Order in Petition No. 67/TT/2015 Page 22 of 26

127 petitioner. The development of subject transmission systems were also discussed in the Standing Committee Meetings on Power System Planning of Northern Region, Western Region and North-eastern Region from time to time. 26. In view of the process of planning, development and execution of the transmission system as discussed hereinabove, we are of the view that the subject transmission systems are of strategic and national importance and are in the long term interest of the economy and consumers of the country. The ±800 kv Biswanath Chariali- Agra HVDC link is the first of its kind in India and is passing through the Chicken Neck area. This HVDC asset once created will serve multiple purpose of evacuating hydro potential of North East, Sikkim and Bhutan to the rest of the country and would also carry power from Agra to Biswanath Charaiali during lean hydro season in NER, thereby serving needs of North East Region as well. In addition to this, the link is serving very important role of integrating the entire Indian Electrical Grid through a robust link. This asset is a unique asset due to its location and strategic importance. This link is a strategically important and vital connection for harnessing the present and anticipated exploitation and optimal utilization of hydro, thermal and renewable energy resources in the country. The strategic importance of the line is established by the fact that a secure and strong linkage for the North-Eastern Region and the rest of the country is now firmly established. Pertinently, the extremely narrow Chicken Neck which is 18 km X 22 km has been optimally utilized solving any future right of way issues in this critical, sensitive and vital area. Therefore, the setting up of such a powerful link is not only important but infuses a high degree of confidence, certainty and assurance for development of hydro Order in Petition No. 67/TT/2015 Page 23 of 26

128 power potential in North-East Region of the country, underlining the fact that no hydel development will have to face bottling up of power or backing down on account of transmission constraints. 27. The Commission agrees with POSOCO that the usefulness and importance of the subject transmission assets should not be seen in the narrow prism of its immediate utilization during the initial years but needs to be assessed over the entire life cycle of the assets which will carry the hydro power from the huge potential in North East for the benefit by the entire country. POSOCO has rightly pointed out that this link would provide the flexibility in power transfer, function as a pseudo phase-shifter and help in mitigating oscillations in inter-area mode and above all, the frequency controllers at BNC would help in operation of NER system, if it were to get islanded due to any reasons. Further, this bi-directional HVDC technology would enable optimal hydrothermal mix and successful integration of renewable energy resources of the country due to its connectivity with the hydro surplus North Eastern Region on one end and balance part of the country through National Grid. Strong interconnection through AC links between all the regions of National Grid would enable exchange of power between North East Region and rest of the country. Moreover, this high capacity interconnection between North East Region comprising of huge hydro potential would go a long way for integration of large renewable energy resources being developed in different parts of the country. Due to direct interconnection, hydro generation can support the variability and intermittent nature of renewable generation. Thus, this vital link is a flagship endeavor of the Indian Power Sector which will benefit the entire country. Order in Petition No. 67/TT/2015 Page 24 of 26

129 28. Since the transmission assets are of strategic and national importance whose benefits shall be derived by the entire country, we are of the view that the charges for the HVDC assets covered in the present petition should be shared by all the regions of the Country. 29. The Commission is conscious of the fact that the capital investments in the assets of the subject transmission systems are huge and the entire assets may not be utilised to their intended level on account of the delay in commissioning of planned hydro potential in NER. The Commission feels that there is a strong necessity to share the burden of capital cost of transmission scheme by way of assistance from the Power System Development Fund (PSDF) by way of one time grant. Accordingly, we direct the petitioner to take up the matter with the Monitoring Committee of the PSDF for assistance in the form of one time grant from the PSDF and with Ministry of Power for grant to reduce the burden of transmission charges on the DICs. We also request Ministry of Power, Government of India to arrange for funds from the PSDF as well as Government grant, considering the subject transmission systems as assets of strategic and national importance, keeping in view the utility of these assets in the long term perspective to the economy of the country. 30. Since, these assets are proposed to be considered as assets of national importance and all the regions are proposed to bear the transmission charges, we consider it necessary to hear the DICs of all the regions. Accordingly, we direct the petitioner to file a revised memo of parties and serve copy of the petition on the DICs Order in Petition No. 67/TT/2015 Page 25 of 26

130 (other than those on whom petition has already been served) by The hearing of the petition will take place on and all DICs are directed to participate in the hearing and share their views. 31. Recovery of the transmission charges determined through this order shall be made as per the principle/methodology to be decided by the Commission after hearing all DICs. -sd- -sd- -sd- -sd- (Dr. M.K.
