(iv) Jeerat (WBSETCL) – Kolaghat (WBSETCL) 400kV S/c line of WBSETCL

3 Agenda for 19th Standing Committee Meeting on Power System Planning of ER

Under Construction:

(v) LILO of Sagardighi – Subhashgram 400kV S/c line at Jeerat (WBSETCL) as a part of ERSS-XV – by POWERGRID

Planned:

(vi) Jeerat (New) – Jeerat (WBSETCL) 400kV D/c line (quad) as a part of ERSS-XVIII – to be implemented as ISTS under tariff based competitive bidding route.

2.4 In the meeting, WBSETCL was requested to submit the detailed survey report regarding feasibility of overhead crossing of existing lines mentioned at 2.3(i) to 2.3(iv) by two D/c lines mentioned at 2.3(v) & 2.3(vi) for termination at GIS extension of Jeerat S/s of WBSETCL. WBSETCL vide its letter dated 05.10.2016 has submitted the detailed survey report, wherein WBSETCL mentioned that overhead crossing of the existing lines are not feasible as it requires huge height of crossing towers as well as considerable space for maintaining required tower falling height. 2.5 Further, a meeting was held on 14.12.2016 at CEA regarding the above issue. Copy of minutes of meeting issued vide letter dated 27.01.2017 is at Annexure-2.2. In the meeting, it was agreed that dismantling the crossing portion of the existing lines (ISTS and State lines) and termination of the existing lines through GIS bus duct might be the appropriate option, as the new lines mentioned at 2.3(v) and 2.3(vi) can be directly terminated on separate double ckt towers at normal height (around 45 meters) to new GIS extension area. The following points were agreed in that meeting and these needs to be ratified in this Standing Committee meeting: 2.6 Following scope may be implemented at Jeerat S/s by POWERGRID as an additional scope under already approved ERSS-XV scheme: (i) Dismantling of dead end towers and termination of existing lines mentioned at 2.3 (i) to 2.3 (iv) through GIS duct to the existing 400kV Jeerat AIS S/s (WBSETCL). (ii) It was also agreed that the termination of the WBSETCL lines mentioned at 2.3 (iii) & 2.3 (iv) through GIS duct to the existing 400kV Jeerat AIS S/s (WBSETCL) shall be implemented as ISTS and included in the approved scope of ERSS-XV being implemented by POWERGRID and cost recovered by POWERGRID as ISTS transmission tariff . (iii) Further, it was also acknowledged that implementation of LILO of Sagardighi-Subhasgram 400kV at Jeerat along with associated line bays shall get delayed by about one year due to addition of above mentioned GIS duct arrangement.

(iv) The new lines mentioned at 2.3 (v) and 2.3 (vi) can be directly terminated on separate double ckt towers at normal height (around 45 meters) to new GIS extension area. 2.7 WBSETCL vide letter dated 04.04.2017 (Enclosed at Annexure-2.3) informed that WBSETCL has considered and accepted the above mentioned scope (Dismantling of dead end towers and termination through GIS Bus duct by POWERGRID under ISTS) of the minutes of meeting held on 14.12.2016 at CEA. 2.8 Members may discuss. 3.0 Creation of 220kV level at the under construction 400/132kV Motihari (TBCB) – Proposal of BSPTCL

3.1 400/132kV (2x200MVA) Motihari GIS substation is under construction through TBCB by M/s Essel Infra. BSPTCL had requested to create 220kV level in the 400/132kV Motihari GIS substation to avoid additional expenditure and time on creating a new 220/132kV Motihari (New) substation planned under intra-state strengthening scheme in 13th Plan. In this regard, a meeting was held at CEA on 18.01.2017 with the representatives of CTU and BSPTCL. Copy of minutes of meeting is at Annexure-3.1. In the meeting it was decided that shifting of the new 220/132kV S/s from Motihari (New) to Raxaul (New) with the following scope of works would be better option. Raxaul (New) S/s: 220/132kV, 2x200MVA (to be implemented by BSPTCL) (a) Sitamarhi (New) – Raxaul (New) 220kV D/c (Twin Moose) (b) Raxaul (New) – Gopalganj 220kV D/c (Twin Moose/ Single Zebra) (c) LILO of Bettiah – Raxaul 132kV D/c line at Raxaul (New) 3.2 In the meeting, following was agreed: (i) The available space in the Motihari substation is not adequate to accommodate the proposed 220kV extension of BSPTCL. Creation of 220kV level would restrict any future expansion plans at Motihari S/s. Load flow results also shows that Motihari (TBCB) – Raxaul and Motihari (TBCB) – Bettiah 132kV D/c lines are critically loaded, when 220kV level is created at Motihari (TBCB) S/s. (ii) The new 220/132kV substation at Motihari is planned primarily to feed the loads of Gopalganj, Bettiah and Raxaul, it was decided to shift the planned substation towards Bettiah/Raxaul keeping the same connectivity. Based on the above observations and load flow studies, the new 2x200MVA, 220/132kV S/s may be created near Raxaul with Sitamarhi(New) – Raxaul(New) 220kV D/c (twin Moose) line and LILO of Bettiah – Raxaul 132kV D/c line.

5 Agenda for 19th Standing Committee Meeting on Power System Planning of ER

(iii) Considering the lower projected load growth of Bihar in 19th EPS, it was suggested that the implementation of Raxaul (New) – Gopalganj 220kV D/c may be taken up at a later date. (iv) BSPTCL may send their proposal on the basis of above discussion to CEA for taking up with forthcoming meeting of the Standing Committee (SCMPSPER) for finalization. 3.3 BSPTCL has sent agenda through their letter dated 28.03.2017 and the same is enclosed at Annexure-3.2. In its agenda BSPTCL proposed to construct a new GSS 220/132 kV, 2x200 MVA near Raxaul with the following scope of works to be implemented by BSPTCL. i) Raxaul (New) S/s: 220/132kV, 2x200MVA

Note: * one unit has been connected to Odisha intra-state system.

5.6 In view to the above, it is proposed to revise the dedicated transmission system of Lanco Babandh project as mentioned below:  Lanco Babandh Gen Switchyard - Angul 400kV D/c line (triple snow bird) 5.7 In the 11th Joint Coordination Committee (JCC) meeting of CTU held on 27-12-2016 LBPPL has indicated its commissioning schedule as Mar 2018. LBPPL has neither awarded construction of its dedicated line nor the line bays at Angul. 5.8 Members may discuss. 6.0 Evacuation of power from Patratu (3x800MW) TPS 6.1 Patratu Vidyut Utpadan Nigam Limited (PVUNL) (3X800+2X800MW) is a joint venture of NTPC Ltd. and the Jharkhand state government owned Patratu Thermal Power Station (PTPS). 6.2 A meeting regarding evacuation of power from Patratu (3x800MW) TPS was held on 20.01.2017 at CEA with NTPC, CTU and JUSNL. Copy of minutes of meeting is at Annexure-6.1. In the meeting, CTU representative informed that Patratu Vidyut Utpadan Nigam Ltd. (PVUNL) has applied for connectivity of 2400MW (Phase-I), to the ISTS system, from Dec, 2020 for their planned Patratu (3x800MW) TPS situated in Ramgarh District of Jharkhand. 6.3 PVUNL informed that 85% of power is allocated to Jharkhand state and 15% is kept as unallocated power. This matter was discussed and it was agreed that as majority of power of Patratu TPS is allocated to Jharkhand, it would be prudent that Patratu TPS is directly connected with JUSNL (Jharkhand

8 Agenda for 19th Standing Committee Meeting on Power System Planning of ER

STU) system. If remaining share (15%) of power of Patratu TPS is to be transferred outside Jharkhand, for which PVUNL may apply for ISTS Long Term Access to CTU (POWERGRID), as per CERC regulations. 6.4 Joint studies were carried out to evolve immediate evacuation system for Patratu (3x800MW) TPS. Studies are available at Annexure-6.1. and accordingly following power evacuation system from Patratu (3x800MW) TPS was evolved: (a) Patratu gen. switchyard – Patratu (JUSNL) S/s 400kV (Quad Moose) D/c line (b) Patratu gen. switchyard – Koderma (JUSNL) S/s 400kV (Quad Moose) D/c line (c) Patratu gen. switchyard – New Chandil (JUSNL) S/s 400kV (Quad Moose) D/c line (d) 420kV, 2x125MVAR bus reactors at Patratu gen. switchyard and 420kV, 1x125MVAR bus reactor at Patratu 400kV bus (e) From Patratu 400/220/132kV substation: (i) Patratu (JUSNL) S/s to Latehar 400kV D/c line (already under construction) (ii) Patratu (JUSNL) to Ranchi (POWERGRID) 765/400kV S/s 400kV D/c line (already under construction) along with LILO of both circuits at Mandar 400/220kV S/s 6.5 In this way, Patratu generation would also get connected to strong ISTS pooling stations viz. (i) Ranchi (POWERGRID) 765/400kV through Patratu (JUSNL) and (ii) Chandwa Pool (POWERGRID) through Patratu (JUSNL) & Latehar (JUSNL) substations of JUSNL. 6.6 Further, the connectivity of Patratu (3x800MW) TPS to Koderma (northern part of Jharkhand) and New Chandil (south-eastern part of Jharkhand) through 400kV high capacity (Quad Moose) double circuit lines would facilitate the transfer the power from Patratu TPS to different load centers in Jharkhand. 6.7 These interconnections would complete the 400kV high-capacity ring viz. Patratu TPS – Koderma – Jasidih – Dhanbad (ISTS) – New Chandil – Patratu TPS in Jharkhand, which shall improve reliability of power transfer within the state. 6.8 From the joint studies, it was also observed that three-phase fault level at both Patratu (3x800MW) TPS and Patratu (400/220kV) substation is about 50kA. Accordingly, it was decided that 400kV bus at Patratu generation switchyard as well as Patratu (400/220kV) substation (JUSNL) would be designed with 63kA fault level for 1sec.

9 Agenda for 19th Standing Committee Meeting on Power System Planning of ER

6.9 JUSNL informed that construction is yet to start at Patratu (400/220kV) substation. Therefore, it was suggested that JUSNL would explore possibility of construction of 400kV and 220kV level at Patratu (400/220kV) substation with fault level of 63kA and 50kA respectively. 6.10 In view of the above, after the approval of the above system in this Standing Committee Meeting, ISTS Connectivity application of PVUNL for Patratu TPS shall be closed and PVUNL may apply for connectivity of its Patratu (3x800MW) TPS to JUSNL (STU of Jharkhand). 6.11 Members may discuss. 7.0 Perspective transmission plan of JUSNL up to 2021-22

7.1 JUSNL informed that at present power demand of Jharkhand is about 1855.5MW (JUSNL area has 1068MW load and DVC area has 787.5MW load). The total load projected for Jharkhand for the year 2021-22 is around 5613MW (4193MW for JUSNL area + 1420MW for DVC area). 7.2 Load flow studies were carried out for projected peak load of Jharkhand as 4193MW for the year 2021-22. 7.3 JUSNL had submitted draft report on perspective transmission plan of JUSNL up to 2021-22. In the meetings held on 26.10.2017 and 20.01.2017, some modifications were proposed by CEA and CTU to incorporate in the study. The copy of Minutes of meeting held on 20.01.2017 is at Annexure- 6.1. JUSNL incorporated these changes and submitted the compliance report vide their email dated 01.02.2017. The compliance report is available in the minutes. 7.4 The following 400/220kV intra-state substations along with downstream connectivity mentioned at Annexure-7.2 were agreed under perspective transmission plan of JUSNL up to 2021-22: (i) Jasidih 400/220kV, 2x500MVA (ii) New Chandil 400/220kV, 2x500MVA (iii) Koderma 400/220kV, 2x500MVA (iv) Mandar 400/220kV, 2x500MVA (v) Dumka 400/220 kV , 2x500 MVA ( with commissioning of Tenughat Ph-2 (1320 MW)) Note: 420kV, 2x125MVAR bus reactors may be installed at all of the above new 400kV substations of JUSNL for voltage control.

7.5 The transmission system planned for JUSNL network along with evacuation system of PVUNL would create a high capacity 400kV ring Patratu TPS – Koderma – Jasidih – Dhanbad (ISTS) – New Chandil – Patratu TPS in Jharkhand, which would improve reliability of power transfer within the state.

Accordingly, 220kV side of the existing three ICTs is terminated at Biharsharif (BSPTCL) S/s which is adjacent to Biharsharif (POWERGRID) S/s. Similarly, for installation of 4th 400/220kV ICT, 220kV ICT bay needs to be constructed at Biharsharif (BSPTCL) S/s along with small 220kV interconnecting line section from 220kV ICT bushing to 220kV ICT bay. 11.3 Accordingly, termination of 220kV side of the 400/220kV, 500MVA ICT-4 at 220kV bus of Biharsharif (BSPTCL) S/s and laying of small 220kV interconnecting line section from 220kV ICT bushing to 220kV ICT bay under ERSS-XX is proposed by POWERGRID. This proposal has already been granted in principle approval by CEA vide our letter no. 77/7/PSPA- II/2017/12 dated 05-01-2017 (Copy at Annexure-11.1). 11.4 Members may approve. 12.0 Baharampur (India) – Bheramara (Bangladesh) 2nd 400kV D/c line Agenda by POWERGRID 12.1 Cross border interconnection between India and Bangladesh through Baharampur (India) - Bheramara (Bangladesh) 400kV D/c line along with 500MW HVDC Back-to-Back terminal at Bheramara, was commissioned in Sept 2013. About 500MW of power is being transferred from India to Bangladesh through this link. 12.2 The capacity of Bheramara (Bangladesh) HVDC station is being upgraded from 500MW to 1000MW by Bangladesh. The system strengthening required

13 Agenda for 19th Standing Committee Meeting on Power System Planning of ER

in the Indian and Bangladesh side for transfer of about 1000MW from India to Bangladesh is already under implementation. In regard to N-1 reliability criteria for 1000MW export to Bangladesh, it was decided that during single circuit outage of Baharampur – Bheramara 400kV D/c line, Bangladesh would restrict/reduce the loading on the operating circuit to the permissible extent with the help of runback control /ramping down facility on the HVDC system. 12.3 Therefore, in order to ensure reliable supply of 1000MW power to Bangladesh from Baharampur, it was decided in the 12th India-Bangladesh Joint Steering Committee (JSC) meeting (on 11th Dec 2016) to construct a 2nd 400kV D/c transmission line from Baharampur (POWERGRID) to Bheramara (Bangladesh) in matching time frame of 2nd 500MW HVDC terminal at Bheramara. Further, in the 12th JSC meeting it has also been decided that, the Indian portion of the line may be implemented by POWERGRID and the mechanism of sharing of transmission charges by Bangladesh for Indian portion of this link would be on same principles as for the first Baharampur – Bheramara link. Accordingly, MoP vide letter no. 9/5/2016-Trans-Vol-2 dated 01-03-2017 has granted approval for implementation of Indian portion of Baharampur (India) – Bheramara (Bangladesh) 2nd 400kV D/c line along with 2 no. 400kV line bays for termination of this line at Baharampur S/s through regulated tariff mechanism route. 12.4 Members may approve.

13.0 High Capacity India-Bangladesh AC Corridor and Formation of second 400kV node in NER-ER Corridor- Agenda by POWERGRID 13.1 In the 5th SCM of NER, it was informed that at present the ER-NER corridor is connected mainly through 400/220kV Bongaigaon S/s in NER. In case of any eventuality at Bongaigaon S/s, there is no second in feed to NER from NEW grid. Therefore, it was agreed that there is a need for 2nd 400kV AC node for interconnection with national grid. The same has been taken into account while planning new interconnection between India and Bangladesh. 13.2 The new interconnection between India and Bangladesh has been planned with high capacity AC link (765kV line to be initially operated at 400kV) to interconnect Bangladesh with Eastern Region (ER) and North Eastern Region (NER) of Indian grid. The scheme has been discussed in the 11th India-Bangladesh JSC/JWG meeting held on 13th July 2016. The scheme consists of establishment and interconnection of following substations in NER, ER and Bangladesh. . In NER: In view of space constraint at Bongaigaon S/s and to provide a reliable take off point in NER, it was proposed to establish new 400kV substation (to be upgraded to 765kV level in future) at Bornagar in Assam, about 50km away from Bongaigaon, through LILO of Bongaigaon

13.4 Detailed scope of works is at Annexure-13.1. This scheme has already been discussed and agreed in the 6th NER SCM held on 03rd Oct 2016 at Imphal. The project report of the above scheme was discussed in the 12th India- Bangladesh JWG/JSC meetings held on 10th-11th Dec 2016, wherein it has been agreed that the modalities of implementation and commercial arrangement etc. need to be worked out jointly by India and Bangladesh. 13.5 Member may discuss. 14.0 Additional power supply to Nepal through Muzaffarpur-Dhalkebar transmission line 14.1 Presently, the Muzaffarpur-Dhalkebar 400kV line is being operated at 132kV in view of non-readiness of 220kV level at Dhalkebar by Nepal. For 132kV operation of the line and supply of about 80MW power to Nepal, one 100MVA, 220/132kV ICT was installed at Muzaffarpur by POWERGRID as an interim arrangement. 14.2 In view of low hydro scenario in Nepal in winters, Govt. of Nepal requested for installation of 2nd 220/132kV, 100MVA ICT at Muzaffarpur for additional power supply. 14.3 Accordingly, a meeting was held at CEA on 02-12-2016, wherein installation of 2nd 220/132kV, 100MVA ICT at Muzaffarpur (spare ICT obtained after replacement of ICT at Purnea) by POWERGRID as a goodwill gesture for

16 Agenda for 19th Standing Committee Meeting on Power System Planning of ER

supply of about 145MW power to Nepal was agreed with following SPS settings at Muzaffarpur S/s: . The power supply to Nepal would be disconnected by opening Muzaffarpur – Dhalkebar 132kV line in case, (a) The power flow through any of the 400/220kV transformers (2x315 + 1x500MVA) at Muzaffarpur exceeds more than 310MW (for 315MVA) and 490MW (for 500MVA). Or (b) If power flow through Muzaffarpur – Dhalkebar 132kV line is more than 140MW. . There is no disruption of power supply to Bihar through the Muzaffarpur S/s.

14.4 The said ICT has already been installed by POWERGRID and upto 145MW (170MVA) power is being supplied to Nepal though the cross-border link. 14.5 Accordingly, members may post facto approve utilisation of 220/132kV, 100MVA ICT released from Purnea for installation at Muzaffarpur (for supply of additional power to Nepal), till operation of Muzaffarpur – Dhalkebar line at 220kV, which is expected by September 2017. 15.0 Modification in - Transmission System for Transfer of power from generation projects in Sikkim to NR/WR (Part-B1)- Agenda by POWERGRID 15.1 In the 18th ER SCM, it was decided to delink the LILO of 2nd circuit of Teesta-III – Kishanganj 400kV D/c (Quad) line at Rangpo from Part-B of the scheme “Transmission System for Transfer of power from generation projects in Sikkim to NR/WR (Part-B)” and take it up as a separate part (Part- B1) of the same scheme as “Transmission System for Transfer of power from generation projects in Sikkim to NR/WR (Part-B1)”. 15.2 LILO of first circuit of Teesta-III – Kishanganj 400kV D/c (Quad) line at Rangpo has been made using HTLS conductor. Accordingly, keeping in view the anticipated problems in construction due to hilly terrain as well as requirement of land for foundation, construction of 2nd LILO line with HTLS would be a better techno commercial solution. 15.3 The two 400kV LILO lines are being constructed on two separate D/c towers, however, in view of RoW constraints near Rangpo the two LILO lines are proposed to be terminated on a Multi Circuit tower at Rangpo end. Multi circuit has been considered along with LILO of first circuit. 15.4 In view of the above, members may approve the following: (i) LILO of 2nd circuit of Teesta III – Kishanganj 400kV D/c (Quad) line at Rangpo with Twin HTLS conductor (ii) 400kV multi circuit tower/line at Rangpo end for termination of LILO of both circuits of Teesta III – Kishanganj 400kV D/c (Quad) line at Rangpo.

16.0 Interim connectivity to generation projects through LILO arrangement - Agenda by POWERGRID 16.1 POWERGRID has informed that numbers of generation projects in different regions were granted Connectivity / Long Term Access (LTA) with strengthening of transmission system. In few cases generation projects were to be commissioned ahead of the anticipated commissioning of the associated transmission system. In such cases, generation projects were given temporary connectivity through loop-in & loop-out (LILO) of nearby transmission lines so as to enable them connect with the grid and commission their generation projects. The temporary connectivity through LILO was to be withdrawn after commissioning of the associated transmission system. Associated transmission system of some of such generation projects have been commissioned and their temporary connectivity through LILO has been disconnected; however, some are still connected through LILO arrangement. 16.2 After hearing the tariff petition for one such case viz. transmission system associated phase-1 IPPs in Odisha (Petition No.112/TT/13), where two generation projects are still connected through temporary LILO arrangement, the Hon’ble CERC has passed the order dated 07.10.15 wherein the following direction has been given in para 65 of the order: "The associated transmission lines were to be constructed by the generation developer matching with the transmission system to be developed by the petitioner and the LILOs constructed by generation developers which were temporary arrangement were to be replaced by the associated transmission system. It is noticed that some of the generation developers have not commissioned the dedicated lines and are continuing to evacuate power through the temporary LILO arrangements. We direct the petitioner to discuss the issue in the Standing Committee Meeting on Transmission and finalize the timeline for replacement of the LILOs of generation developer by dedicated transmission lines within a period of six months from the date of connection of LILO of the petitioner."

16.3 Further, CERC in its order dated 28-09-2016 in Petition no. 30/MP/2014 has directed that: “CTU shall take up all the existing cases of connectivity on interim LILO with the RPC of respective regions within a period of one month from the date of issue of this order for review and decision on disconnection of the interim arrangements through LILO. All such interim arrangements through LILO shall be disconnected within a period of three months of the issue of this order unless the RPC grants extension for continuation of LILO keeping in view of all relevant factors.”

18.5 Upon grant of Connectivity and LTA, OIPL/beneficiaries need to sign requisite agreements for taking up the evacuation system for implementation, failing which the Connectivity and LTA intimations shall be liable for closure/cancellation. 18.6 Members may discuss. 19.0 Additional feed to southern Odisha to improve power supply reliability and enable maximum utilisation of Guzuwaka Back-to-Back HVDC- Agenda by POWERGRID 19.1 POWERGRID has informed that, in the 18th SCM of ER it was noted that in absence of Talcher – Behrampur –Gazuwaka 400kV D/c line by M/s Reliance under TBCB, power flow though Gazuwaka 2x500MW HVDC is restricted under Low Hydro scenario in southern Odisha. Accordingly, it was decided that an additional scheme independent of Talcher – Behrampur – Gazuwaka may be planned and if in future Talcher – Behrampur – Gajuwaka 400kV D/c line is implemented, it would give additional strength to the southern Odisha transmission system and would also improve the low voltage problem in the area. 19.2 Accordingly, a meeting was held at CEA on 30-06-2016 among officials of CEA, CTU (POWERGRID) and OPTCL wherein following ISTS scheme was identified as an additional transmission system to improve reliability of power

22 Agenda for 19th Standing Committee Meeting on Power System Planning of ER

supply to southern Odisha and also to enable maximum utilisation of Guzuwaka Back-to-Back HVDC: (a) Angul – Narendrapur (New) 400kV D/c (Triple Snowbird) line (b) Narendrapur (New) – Gazuwaka 400kV D/c (Triple Snowbird) line

Note: OTPCL would implement new 400/220kV, 2x500MVA Narendrapur (New) substation along with following transmission lines as an intra-state scheme: (i) Pandiabil – Narendrapur (New) 400kV D/c line (ii) Narendrapur (New) – Aska 220kV D/c line (iii) LILO of both the circuits of existing Therubali – Narendrapur 220kV D/c line at Narendrapur (New)

19.3 Load flow study results for the above system was included in the minutes of 18th ER SCM. The above Angul – Narendrapur (New) – Gazuwaka corridor is proposed to be implemented independent of Talcher – Behrampur – Gazuwaka corridor. As mentioned above, if in future 400kV D/c Talcher – Behrampur – Gajuwaka line comes, it would give additional strength to the Odisha transmission system and would also improve the low voltage problem in the area. 19.4 Members may discuss. 20.0 Proposal for stepwise completion of Rajarhat – New Purnea 400kV D/c line under ERSS-V scheme- Agenda by POWERGRID 20.1 POWERGRID has informed that major transmission system under ERSS-V scheme is Rajarhat – New Purnea 400kV D/c (Triple Snowbird) line with LILO of one circuit at Gokarna (WBSETCL) and other circuit at Farakka (NTPC). 20.2 The construction work of 400/220kV GIS substation and 400kV transmission lines at Rajarhat end has been completely brought to a standstill condition due to agitation by local villagers. The West Bengal state administration has advised POWERGRID to stop construction activities at and near Rajarhat substation till further instructions. 20.3 It is likely that Rajarhat – Farakka transmission line at Rajarhat end may not be completed within FY 2016-17 due to volatile political situation. However, Farakka – Gokarna portion of the said line along with associated bays at Farakka may be completed within the FY 2016-17. Further, substation works at Gokarna viz. ICT (under scope of WBSETCL) and 400kV line bays including 80MVAR bus reactor (under scope of POWERGRID) are ready for commissioning. Accordingly, it is proposed to commission Farakka – Gokarna portion of Rajarhat – New Purnea line. Commissioning of Farakka – Gokarna portion would establish connection of Gokarna substation at 400kV level with ISTS enabling improvement of power situation in and around Gokarna and Baharampur area.

21.0 Programme for 11th/12th Plan augmentation of DVC System- Submission of revised plan for approval 21.1 DVC vide its letter dated 05.01.2017 (copy enclosed at Annexure-21.1) informed that approved 11th/ 12th Plan for network augmentation of DVC system, a 220kV new substation was proposed at Gola in Jharkhand with 220kV D/c lines connecting the new Gola S/s to Ramgarh(DVC), MTPS(DVC) and Ranchi(PGCIL) substations. Due to financial crunch and restriction imposed by MoP on investment in respect of DVC transmission System, the construction of new 220kV substation at Gola has been dropped by DVC. The above mentioned 220kV lines (proposed connecting Gola S/s with Ramgarh & MTPS substations of DVC and Ranchi-PG S/S) are complete/nearing completion. To utilize the upcoming 220kV lines to the best extent possible, a revised plan is proposed bypassing the Gola S/s (enclosed with the Annexure-22.1). 21.2 DVC also informed vide its e-mail dated 10.04.2017 (copy enclosed at Annexure-21.2) that load growth at Gola would be met by installation of third 31.5 MVA, 132/33kV power transformer. 21.3 DVC requested to approve the revised plan. 21.4 Members may discuss. 22.0 Installation of bus reactors at 400kV level at substations of STU 22.1 POWERGRID has informed that following 400kV intra-state substations were approved for implementation by respective STUs of Bihar and Odisha in the 18th ER Standing Committee Meeting: (a) Bihar (to be implemented by BSPTCL) (i) 2x500MVA+2x160MVA+2x80MVA, 400/220/132/33kV GIS S/s at Naubatpur (ii) 2x500MVA+2x160 MVA, 400/220/132kV GIS S/S at Bakhtiyarpur (iii) 2x500MVA+3x160MVA+4x80MVA, 400/220/132/33kV GIS S/s at Jakkanpur (b) Odisha (to be implemented by OPTCL) (i) 2x500MVA, 400/220kV sub-station at Meramundali-B (ii) 2x500MVA, 400/220kV sub-station at Narendrapur (New) (iii) 2x500MVA, 400/220kV sub-station at Khuntuni 22.2 With the above mentioned 400kV intra-state substations no bus reactors have been planned by BSPTCL and OPTCL. In order to keep operational flexibility/control over voltages, it is suggested to install suitable bus reactors at 400kV levels in STU system also like in ISTS system. Accordingly, it is proposed that OPTCL and BSPTCL may install 420kV, 2x125MVAr bus reactors at above planned substations except Narendrapur (New) where 420kV, 2x80MVAr may be installed. 22.3 Members may discuss.

23.0 Constraint in transportation of ICT to Farakka (NTPC) under ERSS-XII- Agenda by POWERGRID 23.1 POWERGRID has informed that replacement of 400/220kV, 2x315MVA ICTs with 400/220kV, 2x500MVA ICTs was approved at Patna, New Purnea and Sasaram (Pusauli) substations in the 15th ER Standing Committee Meeting held on 27-08-2013. Therein, it was also decided to install one of the 315MVA ICT released from Patna, New Purnea and Sasaram after replacement at Farakka generation switchyard as 2nd ICT by POWERGRID. The said scopes are being implemented by POWERGRID as part of ERSS- XII scheme. One 400/220kV, 315MVA ICT released from Sasaram (Pusauli) was identified for installation at Farakka. 23.2 The 400kV & 220kV switchyard equipment and Control & Relay equipment associated with installation of 400/220kV ICT are in place at Farakka. While in transit the main ICT tank was stopped by CISF at Farakka Barrage Project (under Ministry of Water Resources). POWERGRID vide letter dated 19-08- 2016 requested permission from Farakka Barrage Project for transportation of the ICT. However, the Barrage Authority vide letter dated 05-09-2016 denied permission for the same. Subsequently, POWERGRID approached The Secretary, Ministry of Water Resources (apex body for Farakka Barrage Project) on 08-09-2016. However, the Ministry of Water Resources declined permission vide their letter dated 23-09-2016 and requested POWERGRID to explore for alternate routes. Previously, all other consignments were transported to Farakka generation project through this route only.

23.3 Accordingly, POWERGRID explored following routes for transportation of the ICT:

(a) Via NEW FARAKKA where a railway underpass (14 ft.) physically prevented the consignment of 17.5 ft. height.

(b) Via DHULIAN-SHANKARPUR, but one intermediate bridge on feeder canal of nearly 500 mtr length is unfit for movement of even LMV: very risky as the condition of the bridge is dilapidated.

(c) Via PAKUR – BARHARWA – NTPC FARAKKA: explored and physically surveyed by POWERGRID & transporter but found not feasible as Major civil work are required for construction of road/bypass over bridges/culverts; en-route, for Trailer with such dimension and weight.

23.4 From above it emerges that the ICT can be transported to Farakka only through the road of Farakka Barrage Project, which has been denied by the apex body (Ministry of Water Resources).

23.5 Thus with no possible transportation options, the ICT has been diverted and stationed at Durgapur S/s of POWERGRID.

26 Agenda for 19th Standing Committee Meeting on Power System Planning of ER

23.6 In the 18th ER Standing Committee Meeting held on 13-06-2016, installation of 3rd 400/220kV, 315MVA ICT at Durgapur (ICT-2 released after replacement at New Purnea S/s) was approved. This is being implemented by POWERGRID under ERSS-XVII (Part-B) scheme.

23.7 In view of the above mentioned transportation constraints it is proposed that ICT diverted from Sasaram S/s (identified for installation at Farakka under ERSS-XII) may be installed at Durgapur S/s as 3rd ICT (under ERSS-XVII Part-B).

23.8 Accordingly, the following modifications in the scope of ERSS-XII and ERSS-XVII (Part-B) schemes are proposed:

(a) Deletion of scope of installation of Sasaram (Pusauli) 400/220kV, 315MVA ICT-2 as 2nd 400/220kV, 315MVA ICT at Farakka generation switchyard from ERSS-XII scheme.

(b) Modification in ERSS-XVII (Part-B) scheme: Installation of above mentioned Pusauli 400/220kV, 315MVA ICT-2 as 3rd 400/220kV, 315MVA ICT at Durgapur instead of earlier approved New Purnea 400/220kV, 315MVA ICT-2.

(c) Shifting of New Purnea (ICT-2) to Durgapur under ERSS-XVII (Part-B) scheme is not required; hence the same may be kept as spare ICT at New Purnea itself. 23.9 Members may discuss. 24.0 Conversion of 50MVAR (3x16.67) bus reactor at Farakka to switchable line reactor under the ERSS-XV due to space constraints in termination of Farakka – Baharampur 400kV D/c (Twin HTLS) line- Agenda by POWERGRID 24.1 POWERGRID has informed that ERSS-XV scheme inter alia includes construction of Farakka – Baharampur 400kV D/c (Twin HTLS) line. One spare future bay has been selected for termination of one circuit of Farakka – Baharampur D/c line at 400kV bus at Farakka generation switchyard, however, due to non-availability of adjacent bay for termination of the other circuit it is proposed to terminate the second circuit in the exiting 50MVAR bus reactor bay along with conversion of this reactor to switchable line reactor. This arrangement would result in connection of 50MVAR switchable line reactor in one circuit of Farakka – Baharampur 400kV D/c line at Farakka end. 24.2 Members may approve. 25.0 Modification in transmission system required for power evacuation from Sikkim IPPs and Operationalization of LTOA/LTA- Agenda by POWERGRID

25.1.2 The dedicated and above mentioned common transmission system associated with Phase-I generation projects in Sikkim (except Chuzchen which was granted LTA separately) were intimated by CTU vide letter dated 07-10-2015. Therein, the dedicated transmission system of Bhasmey HEP was modified from “LILO of one ckt of Chuzachen – Rangpo 132kV D/c line with Zebra conductor at Bhasmey along with associated line bays” to “Bhasmey – Rangpo 132kV D/c line along with associated line bays”. 25.1.3 In the 18th Standing Committee Meeting of ER held on 13-06-2016, it was decided to delink the LILO of 2nd circuit of Teesta-III – Kishanganj 400kV D/c line at Rangpo from the scheme “Transmission System for Transfer of power from generation projects in Sikkim to NR/WR (Part-B)” for Phase-1 IPPs in Sikkim and take it up as a separate part (Part-B1) as “Transmission System for Transfer of power from generation projects in Sikkim to NR/WR (Part- B1)”. From system studies it has been observed that power from the above mentioned Phase-I IPPs can be evacuated with LILO of one circuit of Teesta-III – Kishanganj line at Rangpo with N-1 security criteria (the original transmission system was planned keeping in view N-1 criteria). The 2nd LILO at Rangpo, which is required for meeting the N-1-1 reliability criteria is under DPR stage. 25.1.4 In view of the above, it is found that the following Transmission System for Transfer of power from generation projects in Sikkim to NR/WR from Phase-I Sikkim IPPs (without LILO of 2nd circuit of Teesta-III – Kishanganj 400kV D/c line at Rangpo ) is capable of power evacuation from Phase-I Sikkim IPPs: Common Transmission System (under scope of ISTS) (a) Establishment of 2x500MVA, 400/220kV GIS sub-station at Kishanganj (b) Establishment of 16x105MVA (single phase), 400/220kV and 3x100MVA, 220/132kV GIS substation at Rangpo (c) Establishment of 220kV GIS switching station at New Melli (d) Teesta-III – Kishanganj 400kV D/c line (quad) (e) Kishanganj – Patna 400kV D/c (quad) line (f) LILO of New Siliguri – New Purnea 400kV D/c line (quad) at Kishanganj (g) LILO of Siliguri – Dalkhola 220kV D/c line at Kishanganj (h) LILO of Teesta-V – New Siliguri 400kV D/c line at Rangpo (i) LILO of one circuit of Teesta-III – Kishanganj 400kV D/c line (quad) at Rangpo (with Twin HTLS) (j) Rangpo – New Melli 220kV D/c line (with Single HTLS) (k) LILO of Rangit – Gangtok 132kV S/c line at Rangpo (l) LILO of Gangtok – Melli 132kV S/c line at Rangpo

25.1.5 Govt. of Sikkim and the project developers of Chuzachen and Bhasmey HEPs need to clarify regarding ownership of dedicated transmission lines (viz. Chuzachen – Rangpo and Bhasmey – Rangpo 132kV D/c lines) of the Chuzachen and Bhasmey HEPs. 25.1.6 All the elements of the above mentioned Common Transmission System( mentioned at Para 25.1.4) for Phase-I IPPs except Teesta-III – Kishanganj 400kV D/c (Quad) line has been commissioned. This line (under construction by TPTL) is expected by March 2018. With the completion of this line, the LTOA/LTA of Sikkim Phase-I IPPs shall be operationalised and the generation developers shall be liable for payment of applicable transmission charges. The 2nd LILO at Rangpo, which is under DPR stage would be commissioned at later stage. 25.2 From system studies it has also been observed that common transmission system identified for Phase-1 IPPs is also capable of evacuating power from Tashiding HEP (of Shiga Energy Pvt. Ltd.). Accordingly, it is proposed to modify the LTOA system of Tashiding HEP incorporating the common transmission system for Sikkim Phase-1 IPPs mentioned at Para 25.1.4 above. 25.3 Members may discuss and approve. 26.0 Connectivity granted to Vedanta Ltd. (erstwhile Sterlite Energy Ltd.)- Agenda by POWERGRID 26.1 POWERGRID has informed that Vedanta Ltd. (4x600MW) was granted LTOA of 400MW along with other Phase-1 IPPs in Odisha and LTA of 1000MW along with Phase-2 IPPs in Odisha. For connectivity, Vedanta was to construct two 400kV D/c lines (one for 400MW LTOA and another for 1000MW LTA) from the generation switchyard to Sundargarh (Jharsuguda) S/s of POWERGRID. Subsequently, Vedanta Ltd. has relinquished its entire LT(O)A quantum of 1400MW (Phase-I: 400MW & Phase-II: 1000MW). The first dedicated line is still under construction, whereas the second dedicated

30 Agenda for 19th Standing Committee Meeting on Power System Planning of ER

line has not been taken up for implementation. Connection agreements have been signed between CTU (POWERGRID) and Vedanta Ltd. for both the dedicated transmission lines. 26.2 Vedanta has connected Unit-1, 3 & 4 of the generation project to ISTS system and Unit-2 to Odisha grid. In the 125th OCC meeting of ERPC held on 20-09-2016 under the agenda item no. B.7 – “Persistent under generation and inappropriate operational methodologies vis-à-vis grid requirements in operation of Vedanta, Jharsuguda”, it has emerged that Vedanta has got converted the status of ISTS connected units from IPP to CPP. Accordingly, following was decided in the meeting: (a) Vedanta has to get a fresh connectivity from CTU for their CPP units #1, 3 & 4 (as these units were converted from IPPs to CPPs) as per the decision of 11th Connectivity and LTA meeting of ER held on 13.06.2016. (b) Vedanta has to get NOC from SLDC Odisha for scheduling of their units through ERLDC. (c) Vedanta will be allowed to connect to CTU system only after submission of the above two documents. (d) ERLDC will start scheduling Vedanta CPP Units #1, 3 & 4 only after getting a fresh NOC from SLDC Odissa and with grant of fresh connectivity by CTU. (e) Till then Vedanta would be treated as an embedded customer under the jurisdiction of SLDC Odisha and may remain connected to grid through STU system only (as presently its units are connected to OPTCL system) and do their STOA transaction through SLDC Odisha. (f) In view of all of above, the NOC granted to Vedanta would stand revoked and fresh NOC could be issued subject to fulfillment of the stated conditions (g) Vedanta has to complete the dedicated line within the schedule (i.e. November, 2016) otherwise the LILO may be removed as per the decision of 33rd ERPC and the meeting convened by CEA held on 16.09.2016. 26.3 The matter related to Vedanta was subsequently discussed in a meeting at ERPC on 14-10-2016, wherein following was decided: (a) Control area jurisdiction of Vedanta will be shifted from ERLDC to SLDC, Odisha. (b) CPP units (unit #1, 3 &4) and IPP unit (#2) of Vedanta Ltd along with SEZ (smelter) load shall be kept at 400 kV bus of Vedanta Ltd Switchyard without bus splitting and shall be connected to STU network through 400 kV Vedanta Ltd- Meramundali D/C line. There will be no need to operate the 400kV buses of Vedanta in split bus mode and they should be coupled by completing all the dias. (c) One unit shall be kept as standby till the completion of 400 kV Sterlite- Jharsuguda D/C line. (d) Vedanta Ltd shall be a State embedded entity for all purposes and requisite STU connection would be obtained by Vedanta Ltd i.r.o above.

31 Agenda for 19th Standing Committee Meeting on Power System Planning of ER

(e) The CTU connectivity of Vedanta may be kept in abeyance. The same may be closed/withdrawn from the date of getting the STU connectivity. (f) On change of control area jurisdiction the NOC granted by ERLDC to Vedanta Ltd shall stand revoked. (g) After changeover of control area jurisdiction, the LILO point of 400 kV Rourkela- Raigarh at Vedanta will be interface point of Odisha STU till 30th November, 2016. (h) Subsequently, after the completion of 400kV Sterlite-Jharsuguda D/C line the interface point of Odisha STU will be shifted to Jharsugada. (i) With the change of control area jurisdiction the status of 400kV Sterlite- Jharsuguda D/C line will no more be a dedicated line. So, Vedanta agreed to hand over the line to OPTCL which can be treated as an ISTS tie of OPTCL. (j) Vedanta has to strictly adhere to the schedule for completion of 400kV Sterlite- Jharsuguda D/C line (i.e. 30th November, 2016) as per the decision of 33rd TCC/ERPC and decided in the meetings held in CEA on 16.9.16. In case 400kV Vedanta-Jharsuguda D/C line is not commissioned by that date, the LILO connection to Vedanta shall be withdrawn. (k) Due to change of control area jurisdiction from ERLDC to SLDC Odisha. Vedanta Ltd has to settle the following: (i) ERLDC fees and charges shall be paid by Vedanta Limited as applicable up to the cutoff date. (ii) Previous dues up to cut off date of the pool accounts such as DSM charges along with interest, RTDA, any others has to be settled by Vedanta. (iii) Henceforth, any deviation of Vedanta Limited will be treated as deviation of OPTCL. (iv) After changeover of jurisdiction if in future it is found that any amount in pool account had remained unaccounted by mistake against Vedanta Limited, Vedanta Limited will have to pay the amount into the pool account. (v) For calculation of POC charges and losses Vedanta Limited generation will be considered as generation of Odisha. (vi) Vedanta Limited has to get registered afresh at each RLDC for Short Term Open Access as embedded entity in OPTCL. (vii) Reconciliation of accounts is also required to be done up to the cutoff date by Vedanta. (viii) OPTCL in coordination with Vedanta has to send weekly SEM data to ERLDC by Tuesday Noon.

26.4 For above mentioned deliberations of OCC and ERPC meetings, it emerges that ISTS connected units (Unit-1, 3 & 4) of Vedanta has been converted from IPP to CPP and the same shall now be kept connected with STU connected unit (Unit-2). This would result in connection of all four generation units, Vedanta – Meramundali 400kV D/c line (STU connection) and Vedanta – Sundargarh (Jharsuguda) 400kV D/c line (ISTS connection) to common

32 Agenda for 19th Standing Committee Meeting on Power System Planning of ER

400kV bus. Further, it has been decided that Vedanta shall be embedded entity of Odisha upon completion of Vedanta – Sundargarh (Jharsuguda) line as Vedanta Ltd. has agreed to hand over the line to OPTCL. In such case, the status of the line would change from dedicated transmission line to STU line. 26.5 In regard to connectivity of Vedanta Ltd. with ISTS, interim connectivity arrangement through LILO of one circuit of Rourkela - Raigarh 400kV D/c line at generation switchyard was discussed in the 35th meeting of ERPC held on 25-02-2017 wherein Vedanta Ltd. was provided time extension till 15-04-2017 for completion of the dedicated line and it was decided to open the interim connectivity on 16-04-2017. Accordingly, CTU (POWERGRID) vide letter dated 11-04-2017 requested ERLDC to initiate necessary actions regarding disconnection of the interim arrangement of M/s Vedanta Ltd as per decision of 35th EPRC meeting. 26.6 Member Secretary, ERPC vide email dated 25-04-2017 has informed that the above issue was discussed in 132nd OCC meeting held on 21.04.2017 at ERPC, Kolkata, wherein OCC agreed to extend the interim LILO connectivity till 30th June, 2017 in view of requirement of above mentioned LILO for OPTCL to meet peak summer demand. 26.7 It is understood that interim arrangement of Vedanta Ltd. is yet to be opened. Accordingly, CTU (POWERGRID) vide letter dated 11-05-2017 has requested Member Secretary, ERPC to take suitable necessary action. 26.8 In view of the above, the connection agreement of the first dedicated transmission line shall become null and void upon transfer of the line by Vedanta Ltd. to OPTCL. Accordingly, OPTCL or Vedanta Ltd. need to confirm regarding transfer of above mentioned asset from Vedanta Ltd. to OPTCL. 26.9 Further, with relinquishment of LTA of 1000MW (Phase-II) by Vedanta Ltd. the 2nd dedicated line viz. Vedanta generation switchyard – Sundargarh (Jharsuguda) 400kV D/c 2nd line may not be required. 26.10 Members may discuss. 27.0 Dropping of Banka (PG) – Deoghar 132kV D/c line, which had proposed in 16th SCM-ER meeting 27.1 In the 16th SCM-ER meeting, ERPC had informed that the 132kV Deoghar S/S (JSEB) is being fed through 132kV line(s) from DVC source (132kV Maithon-Jamtara-Deoghar S/C) or from NTPC source (Lalmatia). There is also a feed from BSPTCL source through 132kV Sultanganj- Deoghar S/C line, which is normally kept open due to overloading in Kahalgaon-Sabour- Sultanganj section of BSPTCL system. The Deoghar & Jamtara sub-stations feed important railway loads of 10MW each to Shankarpur TSS & Jamtara TSS and loading on Maithon – Jamtara – Deoghar 132kV S/C line sometimes exceeds 75MW. The reliability of supply to railway loads is being

affected. In view of above, it was agreed to provide an additional supply to Deoghar S/S (JSEB) from 400/132kV Banka S/S (PG) by creating a 132kV Banka- Deoghar D/C lines (about 40 Kms). 27.2 JUSNL vide their letter dated 30.07.2015 addressed to POWERGRID informed that termination of above line at Deoghar is not possible due to space constraint. Further, JUSNL informed that after commissioning of 132kV Jasidih – Deoghar line (about 5km), Deoghar S/s will be able to receive 250MVA of power through Jasidih S/s and Dumka S/s, whereas the transformation capacity at Deoghar is only 150MVA. The matter was discussed in 18th SCMPSP(ER) meeting and it was decided to review the possible interconnections at Deoghar in a separate meeting at CEA with Railways & other stakeholders. 27.3 In regard to above, a meeting was held on 13.06.2017 (MoM is at Annexure-27.1), in which representative of CTU informed that POWERGRID has closed the ERSS-XVI project involving construction of Banka (PG) - Deoghar 132kV D/C line and the same was informed to CEA vide letter dated 27-10-2016. 27.4 Representative of BSPTCL stated that BSPTCL can supply power with exiting system to Deoghar (Jharkhand) through 132kV Sultanganj- Deoghar S/C line during off-peak hours only, as the bus bars capacity at Sultanganj is inadequate. However, supply during peak hours would be possible only after strengthening of bus bar at Sultanganj, which is likely to be completed in next 6 months. 27.5 Chief Engineer (PSPA-II), CEA expressed that in absence of representatives from JUSNL (Jharkhand) and Railways, it is difficult to assess the loading of the network in present situation. 27.6 The proposed Deoghar-Jasidih 132kV D/C line (by JUSNL) and strengthening of 132kV bus at Sultanganj (by BSPTCL) are likely to enhance the reliability of power supply to the Railways TSS at Deoghar. In view of above, it was decided to drop the proposal of construction of Banka (PG) - Deoghar 132kV D/C line. 27.7 Members may discuss.

Minutes of the meeting on lOth September, 2016 after the site visit on 09th September regarding ROW problem for termination of 400kV lines at Jeerat(WBSETCL) S/s for the ERSS-18 scheme

List of the participants is enclosed at Annexure-!. In order to address the RoW constraint for termination of Jeerat(New)-Jeerat(WBSETCL) 400kV D/c line at Jeerat(WBSETCL) as informed by PFCCL, the Bid Process Coordinator for ERSS-18 scheme being implemented through TBCB route, a joint team of officials of WBSETCL, CEA, CTU, PFCCL; POWERGRID(ER-11) visited the Jeerat substation ofWBSETCL on ogth September, 2016. This was followed by a joint meeting of the above officials on lOth September, 2016 at WBSETCL office, Kolkata.

The Director (Projects), WBSETCL welcomed the participants to the meeting. It was stated that WBSETCL participated in the site visit and meeting being the beneficiary of ERSS-15 & ERSS-18 and will extend all help and support required for expeditious execution of the schemes.

Based on the outcome of the site visit, following was discussed in the meeting:

It was noted that the following 400kV lines are existing I under construction I planned at 400/220kV substation of Jeerat(WBSETCL):

Existing: (i) Jeerat(WBSETCL)- Baharampur/Farakka 400kV S/c line ofPOWERGRID (ii) Jeerat((WBSETCL) -Subhashgram/Rajarhaat 400kV S/c line ofPOWERGRID (iii) Jeerat(WBSETCL)- Barkeshwar(WBSETCL) 400kV S/c line ofWBSETCL (iv) Jeerat(WBSETCL)- Kolaghat(WBSETCL) 400kV S/c line ofWBSETCL

Under Construction: (v) LILO of Sagardighi- Subhashgram 400kV line at Jeerat (WBSETCL) as a part of ERSS-15 -by POWERGRID

Planned: (vi) Jeerat(New) - Jeerat(WBSETCL) 400kV D/c line .(quad) as a part of ERSS-18 - to be implemented under tariff based competitive bidding route.

Note : In view of space constraint, the 4 number of bays for termination of 2 no of 400kV Die lines under (v) and (vi) above at Jeerat(WBSETCL) has already been decided to be constructed as GIS bays.

During the site visit and the meeting, the following options were deliberated :

Option 1 : Construction of Multi-circuit Towers for termination of new lines

There is a ROW problem for termination of both the 400kV D/c lines at item (v) & (vi) above to the proposed GIS as extension of existing s/s in the Northern part of the Jeerat(WBSETCL) substation. This would involve crossing of existing 2 nos 400kV D/c lines, which can be addressed by constructing the new: ~OO:;:s on 1[cuit towe~ fr

35 This may however involve construction of 4-5 nos. multi-circuit towers including 2 nos. of multi circuit towers of about 90-100 meter height for crossing the existing 400kV lines. Further, there is a space constraint in termination of the new lines at the proposed GIS, which may involve dismantling of same existing buildings in the substation.

Option 2 : Shifting of existing 400kV lines to the proposed GIS

The termination of existing 2 nos. of 4QOkV D/c lines at Jeerat(WBSETCL) S/s may be shifted from the existing 400kV AIS to the new 400kV GIS proposed in the Northern part of existing substation and the new 400kV lines may be terminated at the existing 400kV AIS.

This would avoid the crossing of existing 400kV lines through multi-circuit towers. This would involve dismantling of some existing D/c towers and construction of new D/c towers and upgradation of 2 no of AIS bay equipment for "termination of 400kV D/c line with quad conductor. This would however involve establishment of 2 number of new GIS bays by WBSETCL for termination of their Jeerat- Bakreshwar and Jeerat- Kolaghat 400kV lines.

Option 3 : GIS substation in the Eastern part of the Jeerat(WBSETCL) S/s

The new GIS may be planned in the Eastern part of Jeerat(WBSETCL) substation in place of proposed GIS in the Northern part. In this option, new 400kV lines would be terminated at the GIS in the Eastern part ofthe S/s.

With this there would no ROW constraints in the termination of new 400kV lines and no requirement of crossing of 400kV existing lines with multi-circuit towers. This would however involve procurement of additional land (about 5 acres) in the Eastern part of the substation.

Option 4 : GIS substation in the Northern part and termination of new lines in the Eastern part of the Jeerat(WBSETCL) S/s

The GIS extension may be planned in the ex1stmg space available in the Northern part of the Jeerat(WBSETCL) substation however the termination of new 400kV lines may be planned in the Eastern part of the substation. The interconnection between the termination gantry of the new lines and GIS may be made through GIS bus duct.

In this option there would be no ROW constraint in termination ofthe new lines and there would be no crossing of 400kV lines with multicircuit towers. This would however involve procurement of small land (about 1 acres) in the eastern part of the substation by WBSETCL for establishment of termination gantry for the new lines.

Option 5 : Shifting of the existing 400kV AIS bay of 4th 400/220kV 315MVA ICT to GIS, and termination of new lines utilizing the space in the Eastern part of the Jeerat(WBSETCL) S/s

The 400kV AIS bay ofthe 4~400/220kV ICT at Jeerat(WBSETCL) may be dismantled and the space available may be utilized for termination of 400kV new lines in the Eastern part of the substation. This

36 /- . . option would require establishment of 5 nos. of GIS bays (4 for lines and 1 for transformer). The interconnection of termination gantry to GIS may be carried out through GIS bus duct.

This option would avoid the crossing of 400kV existing lines through multi-circuit tower. This would however involve establishment of 1 no. of GIS bays by WBSETCL for their 4001220kV, 315MVA ICT(4th).

Recommendation :

After detailed deliberations, option:.__ 1 was considered in view of following: i) Difficulty in acquisition of land (option 3 & 4 ). ii) Availability of space for construction of 400 kV GIS bus duct (four I five circuits) from proposed GIS to terminal gentry of new lines & ICT in the Eastern part of the Jeerat Sis (option 4& 5). iii) Additional cost to be borne by WBSETCL towards construction of new GIS bays due to shifting from existing AIS bays (option-2 & 5)

While deliberating option-1, it was also decided to explore the feasibility of crossing the existing 400 kV lines with 2 no. 400 kV DIC lines mentioned at (v) and (vi) above (one DIC line with twin moose and other with quad moose conductor). In this regard, it was decided that WBSETCL will conduct detailed survey for feasibility .of availability of corridors for the above crossing and termination at the proposed GIS at Jeerat 400 kV sub-station end only. If required location of proposed GIS building may be shifted I reoriented. WBSETCL will complete the survey work by end September, 2016 and share the survey report along with profiles with CEA, CTU and PFCCL.

It was also decided that if required, for accommodating the corridor for two DIC lines, shifting of existing quarters may be considered in ERSS-XV/ ERSS-18.

Based on the detailed survey by WBSETCL, if it is found that corridor for the crossings with 2 no. 400 kV D/c lines is not available, then the crossing with multi circuit towers as given in option-1 would be considered. Shi"fting of existing quarters, if required may be considered in ERSS-XV/ ERSS-18.

38 Minutes of the meeting regarding termination of 400kV lines at Jeerat (WBSETCL) Sis under the ERSS-XV and ERSS-XVIll scheme held on 14.12.2016 at CEA.

List of participant is enclosed at Annexure-}.

1. Chief Engineer (PSPA-II), CEA welcomed the participants. He informed that a joint team of officials of WBSETCL, CEA, CTU, PFCCL, POWERGRID(ER-II) visited the Jeerat 1 1 substation of WBSETCL on 09 h September, 2016 and had meeling on 10 h September, 2016 to address the RoW constraint for termination of Jeerat(New)-Jeerat(WBSETCL) 400kV Die line at Jeerat(WBSETCL). This line is to be implemented through TBCB as part of ERSS-XVIII scheme with PFCCL as BPC. He informed that WBSETCL was requested to submit the detailed survey report regarding feasibility of overhead crossing of existing lines mentioned at 2(i) to 2(iv) by two Die lines mentioned at 2(v) & 2(vi) for termination at GIS extension of Jeerat Sis of WBSETCL.

2. Following 400kV lines are existing I under construction I planned at 4001220kV substation of Jeerat (WBSETCL) :

Existing:

(i) Jeerat(WBSETCL)- Bahararnpur/Farakka 400kV Sic line ofPOWERGRJD

(ii) Jeerat(WBSETCL)- Rajarhat/Subhashgram 400kV Sic line of POWERGRJD (iii) Jeerat(WBSETCL)- Barkeshwar(WBSETCL) 400kV Sic line of WBSETCL

(iv) Jeerat(WBSETCL)- Kolaghat(WBSETCL) 400kV Sic line ofWBSETCL

Under Construction: (v) LILO of Sagardighi- Subhashgrarn 400kV Sic line at Jeerat (WBSETCL) as a part of ERSS-XV- by POWERGRID

Planned:

(vi) Jeerat (New) - Jeerat (WBSETCL) 400kV Die line (quad) as a part of ERSS-XVIli -to be implemented as lSTS under tariff based competitive bidding route.

The map of the above is at Annexure II & Ill. The poinmrise discussions held in the meeting are as follows: 3. Detailed survey report submitted by WBSETCL after site visit of Jeerat Sis on 09.09.2016.

3.1 ChiefEngineer(PSPA-ll) informed that WBSETCL vide its letter dated 05 .1 0.2016 has submitted the detailed survey report for examining the possibility of overhead crossing of existing lines mentioned at 2(i) to 2(iv) by two Die towers or Multi circuit towers mentioned at 2(v) & 2(vi) for termination at GIS extension of Jeerat Sis of WBSETCL.

3.2 Representative of WBSETCL informed that the overhead crossing of the lines either on Double circuit or Multi circuit towers is not feasible. In both the cases, the height of Double Ckt!Multi ckt towers will be in the range of 75-100 m and conductors after overhead crossing of the lines, need to be brought down at normal gantry height (20-25 rn)

39 within the limited space of 90 meters. This configuration will violate the minimum electrical clearance required and to accommodate the lines, many structures including staff quarters would have to be dismantled at existing Jeerat S/s. He added that in the multi ckt tower, the lower ckt will be used for twin moose conductors and upper ckt will be for quad moose. This configuration will have different tensions on tower at different heights.

3.3 Alternatively, WBSETCL proposed that crossing portion of existing lines may be dismantled and the lines may be terminated to the existing AIS bays qf Jeerat S/s through GIS bus duct. This arrangement may cost around Rs. 20-30 crores. WBSETCL further recommended that the expenditure for this might be booked in ERSS-XV or ERSS-XVIII i.e. as part of ISTS. This will remove the RoW constraints for the new lines and the two new separate 400kV D/c corridor can be constructed for ERSS-XV and ERSS-XVIII schemes.

3.4 On a query regarding demolishing of existing staff quarters to construct the additional towers for terminating the new lines at extended Jeerat S/s (GIS), WBSETCL stated that this option is not agreeable to their management.

4. After detailed discussions, Chief Engineer (PSPA-II), CEA expressed that the suggestion of WBSETCL i.e. dismantling the crossing portion of the existing lines (ISTS and State lines) and termination of the existing lines through GIS bus duct might be the appropriate option, as the new lines mentioned at 2(v) and 2(vi) can be directly terminated on separate double ckt towers at normal height (around 45 meters) to new GIS extension area.

Members agreed for the above.

5. Regarding booking of expenditure for above work, mentioned at 4, following was deliberated: (i) Option-1 (Sharing of cost between POWERGRID and WBSETCL): It was suggested that the cost of the above arrangement may be shared equally between POWERGRID and WBSETCL as both are having 2 lines each. WBSETCL did not agree to this option. CE (WBSETCL) stated that their DISCOMS may not agree for this, because this rearrangement work is entirely on account of strengthening in the ISTS. As such, this option was dropped.

(ii) Option-2 (Dropping of 400kV Jeerat (New) - Jeerat(WBSETCL) line under TBCB): POWERGRID stated that the construction of LILO of Sagardighi - Subhashgram 400kV line at Jeerat (WBSETCL) under ERSS-XV does not require any tower crossing as this line could be built along null point between the existing towers. POWERGRID emphasised that the above arrangement is necessary for Jeerat(New) Jeerat(WBSETCL) 400kV D/c line (quad) being implemented through TBCB.

Upon suggestion of dropping the Jeerat(New) - Jeerat(WBSETCL) 400kV D/c line, CE(WBSETCL) stated that this line is very much necessary for meeting the future load growth at Jeerat and should not be dropped. As such this option was also not considered further.

40 (iii) Option-3 (Dismantling of dead end towers and termination through GIS Bus duct by POWERGRID under ISTS) :Under this option, the additional work as suggested by WBSETCL and mentioned at point 4 above, would be implemented as ISTS and to be included in the scope of ERSS-XV being implemented by POWERGRID. Ownership of these works shall be of POWERGRID as ISTS scope and cost of these reconfiguration (including those for the State lines) to he recovered as tariff by POWERGRID. WBSETCL agreed to this proposal subject to approval of their management.

Thus, out of above options, the Option-3 was agreed. WBSETCL was requested to give their official communication/acceptance from their management on the proposal i.e. dismantling the crossing portion of existing line from (ISTS and State lines) and termination of the existing lines through GIS bus duct by POWERGRID and ownership of same to POWERGRJD. (This is similar to LILO of a State transmission line at an ISTS S/s by POWERGRID).

6. POWERGRID clarified that ERSS-XV scheme compnsmg of U LO of Sagardighi Subhasgram 400kV S/c line at Jeerat is already under implementation and the above proposed scope of works of dismantling of part of existing lines mentioned at 2 (i) to 2 (iv) and terminating the same through GIS duct to existing Jeerat S/s could be implemented by POWERGRID under ERSS-XV scheme itself.

7. After further discussions, following was agreed: (i) Following scope may be implemented at Jeerat S/s by POWERGRID as an additional scope under already approved ERSS-XV scheme:

Dismantling of dead end towers and termination of existing lines mentioned at 2 (i) to 2(iv) through GIS duct to the existing 400kV Jeerat AIS S/s (WBSETCL).

(ii) It was also agreed that the termination of the WBSETCL lines mentioned at 2 (iii) & 2(iv) through GIS duct to the existing 400kV Jeerat AIS S/s (WBSETCL) shall be implemented as ISTS and included in the approved scope of ERSS-XV being implemented by POWERGRID and cost recovered by POWERGRID as ISTS transmission tariff. (iii) Further, it was also acknowledged that implementation of LILO of Sagardighi Subhasgram 400kV at Jeerat along with associated line bays shall get delayed by about one year due to addition of above mentioned GIS duct arrangement. (iv) The new lines mentioned at 2(v) and 2(vi) can be directly terminated on separate double ckt towers at normal height (around 45 meters) to new GIS extension area.

1. Chief Engineer (PSPA-11), CEA welcomed the participants. He informed that BSPTCL has requested to create 220kV level in the 400i 132kV (2x200MVA) Motihari GIS substation, which is under construction through TBCB by M/s Esse! Infra. BSPTCL proposed for installation of 400/220kV, 2x500MVA ICTs to avoid additional expenditure and time on creating a new 220/1 32k\/ ~~o·i: ih a ri (New) substation. 2. Representative of CTU stated that Motihari 400/132kV (TBCB) GIS substation is being established through LILO of Barh - Gorakhpur 400kV 0/c (Quad Moose) line under ERSS-VI where space for 5 no. 400kV bays, 5 no. 132kV bays and 400/132kV, 1x200MVA ICT had be~n kept for future expansion. Out of these, 3 no. 400kV bays, 1 no. 132kV bay and ICT space would be utilized for substation extension under ERSS-XXI. The layout of substations plan of 400/132 kV- Motihari S/s is enclo'sed at An nex-11. · 3. The layout of Motihari S/s was examined and the available space shown in the layout was examined in view of proposal for creation of 220 kV leve ~ at same location. 4. Representative of BSPTCL stated that they were taking up with l\1/s Esse! Infra for creation of 22QkV Voltage at 400/132kV Motihari (TBCB). However 1~/s Esse! infra had intimated that 220kV level. could not be created due to space constrarnt. It was decid~d t ha~ CTU may consult Substation expert of POVV~RGR_ID to know the feasibility of creation of 220kV Voltage at 400/132kV Motihari (TBCB). CTU vide their email dated 02.02.2017 have informed that the request of BSPTCL to accommodate 220kV level at Motihari along with 400/220kV, 2x500MVA ICT and 2 no. 220kV line ~ays in the available ~pace of Motihari 400/132kV substation was studied. It was observed that the available space in the fv1otihari substation is not .adequate to accommodate the proposed 220kV extension of BS~TCL. It ... was also pointed out that creation of 220kV level with only one no. 220kV 0/c outlet from 2x500MVA ICTs may not be prudent. Further, creation of 220kV level would restrict any future expansion plans at Motihari S/s. 5. Chief Engineer (PSPA-11), CEA stated that since new 220/132kV substation at Motihari was planned primarily to feed the loads of Gopalganj, Bsniah anci Raxaul, it might be prudent to shift the planned 220/132kV substation towards Bettiah/Raxaul keeping the same connectivity. This would also improve the voltage profile in that area. Representative of CTU said that they would ~a rry out system studi~s under various scenarios of the system. 6. CTU has provided following information vide their e-mail dated 02.02.2017 on the above subject. 1. The new 220/132kV substation at Motihari (New) was planned in consultation with BSPTCL under intra-state strengthening scheme in Bihar to meet its expected 131h plan demand by providing feed to the following: (a) 2nd 220kV feed to Gopalganj 220/132kV S/s (b) Additional 132kV feed to Bettiah/Ramnagar and Raxaul

It may be observed in Exhibit-2 that Motihari (TBCB) - Raxaul and Motihari (TBCB)- Bettiah 132kV D/c lines are critically loaded in the base case itself. iii. Thus, in view of the above mentioned issues and load flow studies it is suggested that 220kV level may not be created at Motihari (TBCB) S/s. iv. BSPTCL also informed that space for new 132kV bays are not available at the existing Raxaui/Bettiah substations. Therefore it was proposed that the new '220/132kV substation can be created near Bettiah/Raxaul by LILO of existing Bettiah- Raxaul 132kV D/c line. v. In view of the above, two alternatives were considered for shifting the proposed new 220/132kV substation, one close to Bettiah and another close to Raxaul. The load flow results with new substation at Bettiah and Raxaul is shown at Exhibit-3 and Exhibit-4 respectively. It may be seen that from the load flow studies (Exhibit-3) that the load distribution on 132kV lines from Bettiah (New) is highly uneven and the flow on Motihari(TBCB) - Raxual 132kV D/c is around its thermal limit in base case itself. However, the issues are resolved when the substation is shifted to Raxual (Exhibit-4). It was observed from the above study results that the Raxaul (New) - Gopalganj 2'20kV D/c is mainly acting as a tie line. Considering the lower projected load growth of Bihar in 19th EPS, it was suggested that the implementation of Raxaul (New) - Gopalganj 220kV D/c may be taken up at a later date. vi. Thus, it is was decided that shifting ofthe new 220/132kV S/s from Motihari (New) to Raxaul (New) with the following scope of works would be better option. Raxaul (New) S/s: 220/132kV, 2x200MVA (to be implemented by BSPTCL) (a) Sitamarhi (New)- Raxaul (New) 220kV D/c (Twin Moose) (b) Raxaul (New) - Gopalganj 220kV D/c (Twin Moose/ Single Zebra) (c) LILO of Bettiah- Raxaul 132kV D/c line at Raxaul (New) 7. Based on the above decision following was agreed: (i) The available space in the Motihari substation is not adequate to accommodate the proposed 220kV extension of BSPTCL. Creation of 220kV level would restrict any future expansion plans at Motihari S/s. Load flow results also shows that Motihari (TBCB)- Raxaul and Motihari (TBCB) - Bettiah 132kV 0/c lines are critically loaded, when 220kV level is created at Motihari (TBCB) S/s. (ii) The new 220/132kV substation at Motihari is planned primarily to feed the loads of Gopalganj, Bettiah and Raxaul, it was decided to shift the planned substation towards Bettiah/Raxaul keeping the same connectivity. Based on above observations and load flow studies, it was proposed that the new

55 Agenda

Sub :- To construct a new GSS 220/ 132 K V, 2X200 MVA near Raxaul in place of Motihari new 220/ 132 KV, as proposed w1der 13 111 plan by BSPTCL.

1. BSPTCL proposed for installation of 4001220kV, 2x500MVA lCTs at the under construction 4001132k V Motihari GIS Substation(TBCB) to avoid additional expenditme and time on creating a new 2201132kV Motihari (New) substation. 2. Motihari (New) substation has been approved in the 18 111 Standing Committee Meeting under intra-state strengthening scheme to meet its expected 13 111 plan demand by providing feed to the follov.ing:- (a) 220kV feed to existing Gopalganj 220/132kV Sis. (b) 132kY 'teed to existing Bettiah and Raxaul GSS. (c) Improve reliability of power supply to Nepal through Raxaul - Parwanipur 132kV line. 3. To know the feasibility of creation of 220kV Voltage at 4001l32kV 1 Motihari, CEA called the meeting on 18 h Jan-17 with the BSPTCL officers and the Substation experts of POWERGRlD. After studying the layout of Motihari Sis and load flow studies by CEA following observation has been made by the experts:- Minutes ofthe meeting is attached. a) Motihari (TBCB) - Raxaul and Motihari (TBCB) - Bettiah 132kV D/c lines are critically loaded in the base case itself. b) It is suggested H1at 220kY level may not be created at Motihari (TBCB) Sis. c) It was proposed that the new 2201132k V substation can be created near Bettiahl Raxaul by LILO of existing Bettiah - Raxaul I 32k V Die line in place ofMotihari (New) 2201132 as earlier proposed in 13th plan. d) fn view of the above. two alternatives were considered for shifting the proposed new 220/l32kV substation. either close to Bettiab GSS or close to RaJ The available space in the Motihari substation is not adequate to accommodate the proposed 220kV extension of BSPTCL. Creation of 220kV level would restrict any future expansion plans at Motihari Sis. Load flow results also shows that Motihari (TBCB) - Raxaul and Motihari (TBCB) - Bettiah 132kV Die lines are critically loaded. when 220kV level is created at Motihari (TBCB) Sis. ~ TI1e new 2201132kV substation at Motihari is planned primarily to feed the loads of Gopalganj, Bettiah and Raxaul, it was decided to shift the planned

56 substation towards Bettiah/Raxaul keeping the sam~? connectivity. Based on above obst:rvations and load now studies. it \\US proposed that the new 220/132kV substation may be created near Raxaul b) the ULO of existing -- Bettiah - Raxaul 132kV 0 /c line \vith the follo'' ing scope of works.

62 Minutes of meeting regarding draft report of JUSNL perspective transmission (2021-22) and Evacuation of power from Patratu TPS (3x800MW) held on 20.01.2017 at CEA

List of participants is enclosed at Annexure-I.

1. Chief Engineer (PSPA-II), CEA welcomed the participants. He informed that draft report submitted by JUSNL for their perspective transmission plan up to year 2021-22 and evacuation of power from Patratu TPS (3x800MW), PVUNL would be discussed in this meeting. A meeting on 26.10.2016 was earlier held in CEA with CTU and JUSNL representatives to discuss the above, after which JUSNL has revised the studies.

2. Evacuation of power from Patratu TPS (3x800MW) Patratu Vidyut Utpadan Nigam Limited (PVUNL) (3X800+2X800MW) is a joint venture of NTPC Ltd. and the Jharkhand state government owned Patratu Thermal Power Station (PTPS).

CTU representative informed that Patratu Vidyut Utpadan Nigam Ltd. (PVUNL) has applied for connectivity of 2400MW (Phase-I), to the ISTS system, from Dec, 2020 for their planned Patratu (3x800MW) TPS situated in Ramgarh District of Jharkhand.

PVUNL informed that 85% of power is allocated to Jharkhand state and 15% is kept as unallocated power. This matter was discussed and it was agreed that as majority of power of Patratu TPS is allocated to Jharkhand, it would be prudent that Patratu TPS is directly connected with JUSNL (Jharkhand STU) system. If remaining share (15%) of power of Patratu TPS is to be transferred outside Jharkhand, PVUNL may apply for ISTS Long Term Access to CTU (POWERGRID), as per CERC regulations.

2.1 Immediate Evacuation System and Evacuation voltage level

2.1.1 Joint studies were carried out to evolve immediate evacuation system for Patratu (3x800MW) TPS and accordingly following power evacuation system from Patratu (3x800MW) TPS was evolved: (a) Patratu gen. switchyard – Patratu (JUSNL) S/s 400kV (Quad Moose) D/c line (b) Patratu gen. switchyard – Koderma (JUSNL) S/s 400kV (Quad Moose) D/c line

63 (c) Patratu gen. switchyard – New Chandil (JUSNL) S/s 400kV (Quad Moose) D/c line (d) 420kV, 2x125MVAR bus reactors at Patratu gen. switchyard and 420kV, 1x125MVAR bus reactor at Patratu 400kV bus (e) From Patratu 400/220/132kV substation: (i) Patratu (JUSNL) S/s to Latehar 400kV D/c line (already under construction) (ii) Patratu (JUSNL) to Ranchi (POWERGRID) 765/400kV S/s 400kV D/c line (already under construction) along with LILO of both circuits at Mandar 400/220kV S/s

2.2 In this way, Patratu generation would also get connected to strong ISTS pooling stations viz. (i) Ranchi (POWERGRID) 765/400kV through Patratu (JUSNL) and (ii) Chandwa Pool (POWERGRID) through Patratu (JUSNL) & Latehar (JUSNL) substations of JUSNL.

2.3 Further, the connectivity of Patratu (3x800MW) TPS to Koderma (northern part of Jharkhand) and New Chandil (south-eastern part of Jharkhand) through 400kV high capacity (Quad Moose) double circuit lines would facilitate the transfer the power from Patratu TPS to different load centers in Jharkhand.

2.4 These interconnections would complete the 400kV high-capacity ring viz. Patratu TPS – Koderma – Jasidih – Dhanbad (ISTS) – New Chandil – Patratu TPS in Jharkhand, which shall improve reliability of power transfer within the state.

2.5 From the joint studies, it was also observed that three-phase fault level at both Patratu (3x800MW) TPS and Patratu (400/220kV) substation is about 50kA. Accordingly, it was decided that 400kV bus at Patratu generation switchyard as well as Patratu (400/220kV) substation (JUSNL) would be designed with 63kA fault level for 1sec.

2.6 JUSNL informed that construction is yet to start at Patratu (400/220kV) substation. Therefore, it was suggested that JUSNL would explore possibility of construction of 400kV and 220kV level at Patratu (400/220kV) substation with fault level of 63kA and 50kA respectively.

2.7 In view of the above, it was suggested that JUSNL may take up the proposed transmission system for Patratu (3x800MW) TPS for approval in the forthcoming meeting of Standing Committee on Power System Planning of Eastern Region. Upon approval, ISTS Connectivity application of PVUNL for Patratu TPS shall be closed and PVUNL may apply for connectivity of its Patratu (3x800MW) TPS to JUSNL (STU of Jharkhand).

3. Perspective transmission plan of JUSNL up to 2021-22

3.1 JUSNL informed that at present power demand of Jharkhand is about 1855.5MW (JUSNL area has 1068MW load and DVC area has 787.5MW load). The total load projected for Jharkhand for the year 2021-22 is around 5613MW (4193MW for JUSNL area + 1420MW for DVC area).

3.2 Load flow studies were carried out for projected peak load of Jharkhand as 4193MW for the year 2021-22.

3.3 JUSNL had submitted draft report on perspective transmission plan of JUSNL up to 2021-22. In the meetings held on 26.10.2017 and 20.01.2017, some modifications were proposed by CEA and CTU to incorporate in the study. JUSNL incorporated these changes and submitted the compliance report vide their email dated 01.02.2017. The compliance report is attached at Annexure-II. The transmission system indicated by JUSNL in the perspective transmission plan is enclosed at Annexure-III.

3.4 In the meeting, it was pointed out that 220kV D/C line considered from Chaibasa (JUSNL) to Ramchandrapur 220/132kV substation was earlier envisaged as Chaibasa (POWERGRID) to Ramchandrapur 220/132 kV substation. In the 18th SCM of ER, JUSNL had informed following outlets for utilization of 4 no. 220kV line bays at Chaibasa (POWERGRID) substation:

(i) Chaibasa (POWERGRID) – Chaibasa (JUSNL) 220kV D/c (ii) Chaibasa (POWERGRID) – Ramchandrapur (JUSNL) 220kV D/c line

3.5 However, as per detailed scope of work submitted by JUSNL, the line at (ii) above is proposed to be terminated at Chaibasa (JUSNL) substation and

65 hence connectivity considered in revised draft report studies i.e. Chaibasa (JUSNL) – Ramchandrapur 220kV D/c line is retained.

3.6 Accordingly, it is imperative that JUSNL may plan a new outlet from Chaibasa (POWERGRID) to utilize the remaining 2 no. 220kV line bays already constructed and get the proposal approved in the forthcoming SCM of ER.

4. Based on the above deliberations, the following was agreed:

4.1 Immediate Evacuation System of PVUNL (3x800MW) (a) Patratu gen. switchyard – Patratu (JUSNL) S/s 400kV (Quad Moose) D/c line (b) Patratu gen. switchyard – Koderma (JUSNL) S/s 400kV (Quad Moose) D/c line (c) Patratu gen. switchyard – New Chandil (JUSNL) S/s 400kV (Quad Moose) D/c line (d) 420kV, 2x125MVAR bus reactors at Patratu gen. switchyard and 420kV, 1x125MVAR bus reactor at Patratu 400kV bus

4.1.1 The following transmission system from Patratu (JUSNL) S/s is already under construction:

(a) Patratu (JUSNL) S/s – Latehar 400kV D/c line (b) Patratu (JUSNL) – Ranchi (POWERGRID) 765/400kV S/s 400 kV D/c line

Note: Patratu (JUSNL) – Ranchi (POWERGRID) 400kV D/c line would be LILOed at Mander 400/220kV S/s by Jharkhand as per perspective transmission plan of JUSNL up to 2021-22

4.1.2 400kV level at Patratu generation switchyard as well as Patratu (400/220kV) substation (JUSNL) would be designed with 63kA fault level for 1sec. 220kV level at Patratu S/s to be designed with 50kA fault level for 1sec

4.1.3 As 85% of power of Patratu (3x800MW) TPS project is allocated to Jharkhand, it was agreed that the generation would be connected to Jharkhand system. In such case, connectivity to ISTS shall not be required. Accordingly, it was decided that the ISTS Connectivity application of PUVNL would be discussed for withdrawal/closure in the next Connectivity and LTA meeting of ER. PVUNL may apply for connectivity of its Patratu (3x800MW) TPS to JUSNL (STU of Jharkhand).

4.2 Perspective transmission plan of JUSNL up to 2021-22

4.2.1 The following 400/220kV intra-state substations along with downstream connectivity mentioned at Annexure-III were agreed under perspective transmission plan of JUSNL up to 2021-22: (i) Jasidih 400/220kV, 2x500MVA (ii) New Chandil 400/220kV, 2x500MVA (iii) Koderma 400/220kV, 2x500MVA (iv) Mandar 400/220kV, 2x500MVA

4.2.2 The transmission system planned for JUSNL network along with evacuation system of PVUNL would create a high capacity 400kV ring Patratu TPS – Koderma – Jasidih – Dhanbad (ISTS) – New Chandil – Patratu TPS in Jharkhand, which would improve reliability of power transfer within the state. The intra-state system of Jharkhand would also get well interconnected at various ISTS points for smooth power exchange. 4.2.3 420kV, 2x125MVAR bus reactors may be installed at the new 400kV substations of JUSNL for voltage control. 400kV and 220kV levels at the new substations may be implemented with fault level of 63kA and 50kA respectively.

4.2.4 The SLD of 400kV & 220kV network and geographical map of JUSNL system for the JUSNL network for the year is attached at Annexure- IV (a), (b) & (c).

4.3 Utilisation of balance 2 no. 220kV line bays at Chaibasa

110 Minutes of the meeting related to Connectivity of Railway TSSs with ISTS network in Mughalsarai-Howrah Railway Route, held on 20.04.2017 at CEA.

List ~f participants is enclosed at Annexure-1. ,)., \1~ Member (Power System), CEA welcomed the participants and stated that in an earlier meeting held in CEA on 07.10.2016, in regard to connectivity of Railways with ISTS network for the Mughalsarai - Howrah and the Delhi - Bharuch routes, it was decided that the issue of disconnection or paralleling of Railway TSS with STU network, would be further studied. To discuss the matter, the meeting was being held.

The following were discussed in the meeting:

1: CE (PSPA-11), CEA informed that Railways has proposed to connect their Trac.tiRn ·-:.! ;;o, Sub-stations (TSS) with ISTS points in Mughalsarai-Howrah route. The identified ISTS substations are Patna, Gaya, Maithon, Durgapur, Lakhisarai and Subhashgram. He expressed that simultaneously paralleling of Railway TSS with STU and ISTS network may increase the fault level and would result in stranded infrastructure. He stated that, at present, Railways are getting supply from STU network on this route. He asked Railways about the necessity of another infrastructure for Railways, when they are able to draw power from STU network in a reliable manner. 2. Director (Railways) informed that the decision of Railways to get connected to ISTS network and disconnection from STU network is purely based on economics of getting cheaper power from other sources through ISTS network. He, however, confirmed that they are getting reliable power from STU network. He further informed that the infrastructure for Railways connectivity to STU network was funded by Railways and built by respective STUs as a deposit work for Railways. As per the contract agreement with STUs, the assets are maintained by STUs. 3. Member (Power System), CEA requested Railways to share the economic analysis of shifting of Railway load from STUs/DVC to ISTS in this route. Director (Railways) said that he would send the report immediately. 4. D.C.E (DVC) stated that Railways connectivity to DVC network (from generator point upto 25 kV system) was created and funded by DVC and not by Railways. At present i._::._) total Railway load of DVC is about 320MW, which they supply to Railway, at an 'average cost of Rs.4.80/ unit: Which is quite competitive price considering the higher reliability of power supply from two sources specially for Railways. He also stated that DVC has already tied up for generation projects and made investment in transmission considering recent specific request from the Railways. Hence, proposal of Railways to disconnection from DVC would result these infrastructure, as redundant

111 \ \ \ \ \ and investment as non-performing asset for DVC. Before agreeing to Railways \ proposal based on their economic consideration, economic aspects of DVC/STUs \ should also be considered. 5. Director (Railw(J.ys) agreed with the DVC statement and stated that considering above facts, the case ofDVC would be resolved mutually. However, he further added that the scheme for disconnection in Mughalsarai-Howrah route have been planned in a holistic way and as per plan, Railway would be disconnected from DVC also on this route. He said that these disconnections would be carried out in accordance with the agreements between Railways and the STUs/DVC. He indicated that Railways can disconnect from STU/DVC, giving legal notice as per these agreements. 6. ChiefEngineer (PSPA-11), CEA stated that Railways may intimate the STUs and I)VC .!--t-""j,_ regarding the date from which Railways would likely to disconnect, so that they pl;m for utilization of those network for other purposes, if possible. Representative of Railways replied that the disconnection may takes place in around (3-5) years time. Railways said that they can send advance intimation to STUs for disconnectio:n, once the scheme of connection with ISTS gets agreed in the Standing Committee of CEA. 7. Director(BSPTCL) stated that Railways connectivity network with STU were built as deposit work by STU for Railways, however as per the legal agreement, the infrastructure belongs to the STU. He added that the load of Railways TSS would be around 80 to 100 MW at each 220 kV point and this would lead to under-utilisation of bays/lines/space at each ISTS points and thus is not an optimal planning as per the Electricity Act. He added that space for 2 No. 220kV Bays at ISTS S/s have been kept for future expansion of states and in this case the user would be only the Railways and · thus no space would be left for STUs to meet their future requirement.. He also informed that there is no space at Patna and Gaya ISTS S/s for Railways connectivity. 8. Chief Engineer (UPPTCL) stated that the infrastructure for Railways was created considering Railways as important customer in UP. Now after disconnections, bays etc . . would have to be utilised for other purposes. In future, if railways agam reqmres connectivity from STUs, this would not again be allotted to them. 9. AGM (POSOCO) expressed that for reliable supply to Railways, the STU and ISTS network may be kept in. parallel. This would be, as per CEA's Planning Criteria of Power System Planning for important loads. ChiefEngineer (PSPA-1), CEA stated that generally connectivity from two points i.e both STU and 'TSTS are not recommended. Two connectivity's for Railways, however can be considered either from STU or ISTS. GM(REMCL) Railways stated that they have planned their connectivity to TSS from two ISTS supply points and shared their scheme (a copy of which is given at Annex-11)

112 l l I 10. Director (BSPTCL) stated that Railways load at Bihar would be around 200MW. Recently, Bihar have allowed open access for 50MW to Railways and the remaining I may be granted gradually. He stated that state network would become stranded after building Railway network with ISTS. This would be national wastage of resources and Public money. He added that Railways may be advised to again look into the economics of connectivity to ISTS points, as many of the states have already granted/ are in the process of granting NOC for open access and as such there is no justification for getting connected with ISTS. 11. Regarding control area for scheduling, metering and deviation, AGM(POSOCO) infol111ed that as per CERC order, there would be two control areas, in each state i.e.one for RLDC and the other for SLDC( if they have connections from STU s also) for al:;lqye ~ ;.~~f,--"· purposes. 12. It is noted that no representative from West Bengal and Jharkhand was present in the meeting. 13. On the basis of above following was concluded.

1. Railways has to share the economic analysis of shifting of Railway load from STUs/DVC to ISTS in this route, which is basis of their proposal. Representative of Railways intimated that they would soon send the report.

11. As the transmission system is planned in an integrated manner, Railways were advised to again look into the economics of connectivity to ISTS points, as many of the states have already granted /are in the process of granting NOC for open access.

111. Transmission system for delivery of power to Railways need to be planned in , according with the Electricity Act 2003 and thus taken up for discussion with Standing Committee cop.stituted by CEA.

IV. No representative from West Bengal and Jharkhand was present in the meeting .. Meeting ended with vote of thanks to the Chair.

121 Annexure-18.1

Transmission system for Odisha UMPP

Introduction:

Orissa Integrated Power Limited (SPV for Odisha UMPP) has applied for LTA of 4000MW from Odisha UMPP (Bhedabahal, Odisha) with the following allocation:

Beneficiary Quantum (MW) Odisha 1300 MW ER 1300 MW Madhya Pradesh 400 MW Chhattisgarh 200 MW WR 600 MW Tamil Nadu 300 MW SR 300 MW Rajasthan 400 MW Uttarakhand 200 MW Punjab 500 MW Haryana 400 MW Uttar Pradesh 300 MW NR 1800 MW Total 4000 MW

Odisha UMPP (4000MW) is expected to be commissioned by 2021-22 time-frame. Accordingly, studies have been carried out for 2021-22 time-frame to finalise transmission system for evacuation of power from Odisha UMPP.

Transmission System:

It has been assumed that Odisha UMPP shall consist of 6 generation units of 660MW each. As per coordinates provided, UMPP shall be established in proximity of the existing 765/400kV Sundargarh (Jharsuguda) substation of POWERGRID. On connecting the generation project to Sundargarh 765/400kV S/s, it was found that the fault levels were exceeding the rated limits. Thus, in order to control the fault level, split bus arrangement has been considered at UMPP switchyard with two bus sections having 3 generation units of 660MW each.

From the above mentioned power allocation it is observed that about 1800MW is to be transferred to beneficiaries in NR and about 600MW to WR. Accordingly, it is proposed that high capacity 765kV AC transmission lines be planned from Odisha UMPP in such a manner that power could be transferred to two routes viz. from ER to WR and from ER to NR.

Accordingly, the following alternatives have been considered:

Alternative-1 (transmission system approved in 17th ER-SCM) [Study Results at Exhibit-1]

Page 1 of 3

122  Establishment of new 765/400kV 3x1500MVA Pooling Station near Sundargarh  LILO of Sundargarh-A – Raipur Pool 765 kV D/c line at Sundargarh (New)  Odisha UMPP – Sundargarh New 765kV 2xD/c line  Establishment of new 400/220kV 4x500MVA Station at Badarpur (New)  Sundargarh (New) – Badarpur (New) ±800kV HVDC Bipole Line  ±800kV HVDC 3000MW (upgradable to 6000MW in future) Terminals at Sundargarh (New) and Badarpur (New)

Due to space constraint at 765kV bus section at Sundargarh-A, LILO of either Sundargarh-A – Dharamjaygarh 765kV D/c line or Sundargarh-A – Raipur Pool 765kV D/c line has been considered at one section of Odisha UMPP switchyard. The other section of Odisha UMPP switchyard is proposed to be connected to either Sundargarh-B section or alternatively to Gaya S/s via Ranchi (New) for transfer of power towards NR.

Alternative-2 [Study Results at Exhibit-2(a) & 2(b)]

 Split bus at Odisha UMPP (3x660MW in Section-A and 3x660MW in Section-B)  LILO of Sundargarh-A – Dharamjaygarh 765kV D/c line at Odisha UMPP-A Or LILO of Sundargarh-A – Raipur Pool 765kV D/c line at Odisha UMPP-A  Odisha UMPP-B to Sundargarh-B 765kV D/c line  Ranchi (New) – Gaya 765kV D/c line

Alternative-3 [Study Results at Exhibit-3]

 Split bus at Odisha UMPP (3x660MW in section-A and 3x660MW in Section-B)  LILO of Sundargarh-A – Dharamjaygarh 765kV D/c line at Odisha UMPP-A Or LILO of Sundargarh-A – Raipur Pool 765kV D/c line at Odisha UMPP-A  Odisha UMPP-B to Ranchi (New) 765kV D/c line  Ranchi (New) – Gaya 765kV D/c line

Observations:

From the above study results, it is observed that power flow in all the alternatives are within acceptable limits. However, following are the observations for the above mentioned alternatives:

Alternative-1: It is observed that existing/under-construction evacuation corridors from Sundargarh (Jharsuguda) are under-utilized. Further, as the expected cost of this alternative would be high, this alternative does not appear to be the optimised transmission system.

Alternative-2:

Page 2 of 3

123 It is observed that loading of transmission lines is similar whether LILO of Sundargarh-A – Dharamjaygarh 765 kV D/c line is considered at Odisha UMPP-A or LILO of Sundargarh-A – Raipur Pool 765 kV D/c line is considered at Odisha UMPP- A section. Therefore, it is proposed that LILO of one of the 765kV D/c lines be done at Odisha UMPP-A bus section depending on the proximity of transmission line route from the UMPP. Odisha UMPP-B is proposed to be connected to Sundargarh-B through 765kV D/c line

The power flows from Sundargarh-A and Sundargarh-B sections to Ranchi (New) via Dharamjaygarh substation in WR through Sundargarh – Dharamjaygarh – Ranchi (New) 765kV corridor. Further, there is a high capacity 765kV ER-NR corridor from Gaya in ER to Varanasi and Balia substations in NR. Thus, by completing the missing link i.e. Ranchi (New) – Gaya 765 kV D/c line, it shall be possible to connect southern and northern portion of ER through strong 765kV link and this shall enhance power flow on WR-ER-NR and ER-NR corridors and also increase utilisation of the existing transmission capacity in ER-NR corridor in a better way.

Further, in Alternative-2 by construction of Ranchi (New) – Gaya 765 kV D/c line, the Sundargarh-A – Odisha UMPP-A – Dharamjaygarh – Ranchi (New) – Gaya – Varanasi/Balia 765kV corridor gets completed.

Alternative-3: In this alternative, Odisha UMPP-A section is proposed to be connected same as mentioned in Alternative-2. However, in order to push more power through ER-NR corridor, Odisha UMPP-B bus section has been directly connected to Ranchi (New) through 765kV D/c line along with extension of 765kV D/c corridor to Gaya for further transfer of power to Varanasi and Balia substations in Northern Region.

Power flow on the existing Dharamjaygarh – Ranchi (New) 765kV 2xS/c lines is low in the base case itself. With construction of UMPP to Ranchi corridor it is observed that power flow on Dharamjaygarh – Ranchi (New) link is further reduced, as the two corridors become a parallel path (UMPP – Ranchi and UMPP – Dharamjaygarh – Ranchi).

Conclusion:

From above, Alternative-2 is found to be the most optimised/suitable one. In this alternative only by construction of Ranchi (New) – Gaya 765 kV D/c line, power flow in WR-ER-NR and ER-NR corridors is enhanced. This shall also result in better utilisation of existing and under construction inter-regional transmission lines.

Accordingly, following transmission system is proposed for Odisha UMPP:

The above mentioned ::ZOKV lines (proposed connecting Gola SIS with·Ramgarh & MTPS substations of DVC and Ranchi-PG 5/5) are complete/nearing completion: To !:!Jilise the up-coming 220KV lines to the best extent possible, a revised plan (copy enclosed) iS'p_roposed bypassi(lg theiGgl<:rSIS,(now dropped).

The revised plan, as proposed, may please be approved.· ($; :.; ..

~~135 Minutes of Meeting regarding 132kV Banka (PG)- Deoghar D/c transmission line held on 13.06.2017 at CEA~~

~~List of participants is enclosed at Annexure-1~~

1. Chief Engineer (PSPA-11), CEA welcomed the participants and highlighted about the purpose of the meeting. He informed that Banka (PG) - Deoghar 132kV DIC line (about 40 km) was agreed in the 01st -2014 Standing Committee Meeting on Power System Planning in Eastern Region(ER) (16th SCMPSP(ER)) held on 02nd May 2014.

2. In the 16th SCM meeting, ERPC had informed that the 132kV Deoghar SIS (JSEB) is being fed through 132kV line(s) from DVC source (132kV Maithon Jamtara:Deoghar SIC) or from NTPC so;urce (Lalrn~tja). There is also a feed from BSPTCL source through 132kV Suftanganj- Deoghar SIC line, which is normally kept open due to overloading in Kahalgaon-Sabour- Sultanganj section of BSPTCL system. The Deoghar & Jamtara sub-stations feed important railway loads of 1OMW each to Shankarpur TSS & Jamtara TSS and loading on Maithon - Jamtara - Deoghar 132kV SIC line sometimes exceeds 75MW. The reliability of supply to railway loads is being affected. In view of above, it was agreed to provide an additional supply to Deoghar SIS (JSEB) from 4001132kV Banka SIS (PG) by creating a 132kV Banka- Deoghar DIC lines (about 40 Kms).

3. JUSNL vide their letter dated 30.07.2015 addressed to POWERGRID(copy enclosed at Annex-11) informed that termination of above line at Deoghar is not possible due to space constraint. Further, JUSNL informed that after comrnissi.oning of 132kV Jasidih - Deoghar line (about 5km); Deoghar Sis will be able-tg·re~eive 250MVA of power through Jasidih Sis and Dumka Sis, whereas the transformation capacity at Deoghar is only 150MVA. The matter was discussed in 18th SCMPSP(ER) meeting and it was decided to review the possible interconnections at Deoghar in a separate meeting at CEA with Railways & other stakeholders.

4. In the meeting, representative of BSPTCL stated that Banka (PG) substation is having 2x200 MVA 4001132 kV ICTs at present, which are sufficient to meet the loads of BSPTCL only. PGCIL informed that Banka substation is proposed to be augmented with addition of 1x315 MVA, 4001132kV ICT under ERSS-XX (approved in 18th SCMPSP(ER)). BSPTCL representative suggested that power supply to Deoghar (Jharkhand) from Banka (PG) may be commenced only after commissioning of additional 315 MVA ICT at Banka (PG), which is planned under 13th plan.

~~5. Chief Engineer (PSPA-11), ,CEA enquired about reason for keeping 132kV Sultanganj- Deoghar SIC line open under normal condition.~~

6. Representative of BSPTCL stated that BSPTCL can supply power with exiting system to Deoghar (Jharkhand) through the above line during off-peak hours only, as the bus bars capacity at Sultanganj is inadequate. However, supply

136 during peak hours would be possible only after strengthening of bus bar at I Sultanganj, which is likely to be completed in next 6 months. 7. Representative of CTU informed that POWERGRID has closed the ERSS-XVI project involving construction of Banka (PG) - Deoghar 132kV 0/C line and the I sawe was informed to CEA vide letter dated 27-10-2016. 8. Chief Engineer (PSPA-11), CEA expressed that in absence of representatives from JUSNL (Jharkhand) and Railways, it is difficult to assess the loading of the network in present situation.

9. Thus, the proposed Deoghar-Jasidih 132kV 0/C line (by JUSNL) arid strengthening of 132kV bus at Sultanganj (by BSPTCL) are likely to enhance the reliability of power supply to the Railways TSS at Deoghar. In view of above, it was decided to drop the proposal of construction of Banka (PG) - Deoghar 132kY DIC line in the next Standing Committee meeting. ."\
