Member (PS), CEA welcomed the participants. After brief introduction of the participants, he requested CE(PSPA-II), CEA to take up the agenda.

List of the participants is enclosed at Annexure-I.

1. Confirmation of the minutes of 3rd meeting of Eastern Region PowerCommittee (Transmission Planning) (ERPCTP).

1.1 Director (PSPA-II), CEA stated that minutes of the 3rd meeting of Eastern Region Power Committee (Transmission Planning) (ERPCTP) held on 09th Feb 2021 were circulated vide CEA letter No. CEA letter No. CEA-PS-12-15/2/2018-PSPA-II Division-Part(1)/I/14953/2021 dated 01st April, 2021. No comments were received from constituents on the minutes.

1.2 Minutes of 3rd meeting of ERPCTP were confirmed.

A. ToR 2(i) – QUARTERLY REVIEW AND STRENGTHNING OF INTER-REGIONALTRANSMISSION SYSTEM

Carry out a quarterly review of the Transmission system in the region; assess the growth in generation capacity and the demand in various parts of the region; and draw up proposals for strengthening inter-Regional transmission system. The transmission planning is required to keep in mind the areas where the generation is likely to grow and areas where load demand will grow so that the transmission system at any point of time is capable to meet the demand in every corner of the country and comply with the mandate under the Tariff policy of developing transmission system ahead of the generation for ensuring smooth operation of the grid.

2. Quarterly Review of transmission line and substation.

2.1 Director (PSPA-II), CEA presented a list transmission lines and substations/ICTs commissioned in the Eastern Region during Q4 of 2020-21 and Q1 of 2021-22.

2.2 ERLDC stated that the 220 kV Subhashgram(PG) - Baruipur D/C line has not yet been commissioned. The expected time of commissioning is Dec, 2021. Line is only charged from Subhashgram end.

2.3 The updated list of transmission lines and substations/ICTs commissioned in the Eastern Region during Q4 of 2020-21 and Q1 of 2021-22 is enclosed at Annexure-II. He requested the constituents to send the updated inputs, if any, to PSPM division of CEA.

3. Assessment of growth in generation capacity and demand in the region

3.1 Director (PSPA-II), CEA presented the list of existing/ planned generationcapacity (MW) and actual/anticipated peak demand of states in Eastern region.


539

He requested members to update the data, if any, for better projection/ reassessment.

3.2 Representative of BSPTCL stated that there is no generation capacity of Bihar for Coal based generation as Bihar has sold their stake in the Thermal power projects to NTPC, SJVN etc. Therefore, the generation capacity mentioned as 660 MW in the data should be NIL. Bihar also stated that the peak demand for 2020-21 was 6676 MW instead of 5995 MW.

3.3 West Bengal stated that their anticipated demand would be higher than presently projected and they will inform CEA within a month.

3.4 Chief Engineer (PSPA-II), CEA stated that the peak demand met/energy served figures are compiled by GM division of CEA for all the stated and the same has been presented here. He requested the constituents to send their revised figures of peak met/energy served figures to GM division of CEA through concerned RPC secretariat, if there is any discrepancy.

3.5 ERLDC stated that Jharkhand demand does not include JUSCO DISCOM demand which is otherwise included in the EPS demand.

3.6 Chief Engineer (PSPA-II), CEA stated that the SLDC should take demand of all distribution licensee in their state into account in its daily reports and accordingly report to CEA/RPC/RLDCs. However, if JUSCO demand is being met from captive power plant, it should be received with respect to EPS as well.

3.7 ERPC stated that the JUSCO and TATA power demand are not taken into account as they don’t draw power through Jharkhand STU. JUSCO is a distribution licensee which supplies power received from its captive power plant. It takes power from JUSNL in case of emergency.

3.8 Representative of DVC stated that two feeder of TATA power are connected in consumer mode (200 MW) and one in scheduling mode (100 MW). Also, JUSCO is connected as consumer mode (86 MW) through DVC system.

3.9 The updated list of list of existing/ planned generation capacity (MW) and actual/anticipated peak demand of states in Eastern region is available at Annexure-III. The list of generation project is enclosed at Annexure-IV.

4. Requirement for strengthening of Inter-regional transmission system

4.1 Director (PSPA-II), CEA stated that as per ToR-I of ERPC-TP, the committee has to “Carry out a quarterly review of the Transmission system in the region; asses the growth in generation capacity and the demand in various parts of the region; and draw up proposals for strengthening inter-Regional transmission system” However, MoP vide OM dated 20th May, 2021 amended ToR of NCT. This OM mentions that:


540

“2(i) The Regional Power Committees (Transmission Planning) can make meaningful recommendations only regarding their own Region. They cannot decide on transfers across region.”

He also stated that in view of the amendment in ToR of NCT, it is proposed not to discuss Inter-regional transmission system in this meeting to ensure compliance of the above OM, at this stage. Once all India level generation or surplus/deficit scenario gets confirmed in NCT, the same would be informed in the next meeting.

4.2 Chief Engineer (PSPA-II), CEA stated that it was earlier decided that assessment on All India basis carried out by NCT/CTU will be discussed in the RPC-TP. However, no assessment report has been received from NCT/ CTU. As and when, the data is made available by NCT/CTU, the same would be informed to ERPC-TP in subsequent meeting.

4.3 After deliberations, the members noted the MoP direction and agreed to drop the agenda till inputs from NCT.

5. Review of Transmission system by system operator

5.1 Director (PSPA-II), CEA presented the list of transmission line constraints, ICTconstraints, nodes experiencing high voltage/ low voltage during Q2 of 2020-21. He stated that most of the constraints will be addressed afterimplementation of transmission system agreed in meetings of ERPCTP. Herequested the constituents to expedite the implementation of agreed system.However, some constraints require planning of additional elements. List ofconstraints faced, is at Annexure-V.

5.2 220 kV Budhipadar-Lapanga D/C, 220 kV Budhipadar Vedanta D/C and 220 kV Rourkela-Tarkera D/C ERLDC stated that these lines are normally overloaded. 220 kV Rourkela-Tarkera D/C is overloaded due to high drawal at Tarkera side by Odisha. Thereare 4 ICTs at Rourkela and two outgoing feeder to Tarkera. Regarding 220 kVBudhipadar-Lapanga D/C, 220 kV Budhipadar Vedanta D/C, there are manycaptive power plants at Buddhipadar. These captive power plants inject highpower at Budhipadar and this makes the lines overloaded.

ERPC stated that due to some disturbance and blackout at Budhipadar, acommittee was constituted to look into the issue. A special meeting was held inwhich Odisha presented study for long term plan wherein they planned toconstruct 2nd 220 kV Rourkela-Tarkera D/C which will alleviate loading fromexisting 220 kV Rourkela-Tarkera D/C line and the ICTs at Rourkela will beproperly utilized. After commissioning of this new line, Odisha will disconnectVedanta from 220 kV level and connect it to existing 400/220 kV level at Sterlite.In ERPC OCC meeting, Odisha has stated that they have planned fordisconnecting Vedanta from Budhipadar but no study has been done. A


541

separate meeting will be held with OPTCL, Odisha SLDC, OPGC, ERPC and ERLDC for short term planning to relieve these lines.

Chief Engineer (PSPA-II), CEA stated that this operational issue may pleasebe resolved at ERPC forum. After the discussion at ERPC level, ERPC maysend the proposal with recommendations to include in the next meeting ofERPCTP.

5.3 220 kV Patna-Sipara T/C line BSPTCL informed that the reconductoring of ckt-1 and ckt-2 of 220 kV Patna-Sipara T/C line will be taken up after commissioning of 400kV Jakhanpur andNaubatpur substations (expected by Dec, 2021) as these are feeding criticalload connected at Patna and shutdown will not be available. Accordingly, thereconductoring work is expected to be completed by July, 2022.

5.4 220 kV Rajarhat-Newtown D/C and 220 kV Suhashgram- EMSS D/C lines Representative of WBSETCL stated that for relieving the 220 kV Rajarhat-Newtown D/C and 220 kV Suhashgram- EMSS D/C, they have implementedRajarhat (POWERGRID) – New Town AA2 220 kV D/c, Rajarhat (PGCIL) –Barasat/Jeerat 220 kV D/c and Subashgram (POWERGRID) – Baraipur 220 kVD/c lines. But, due to RoW problem, New Town AA2 could not be completed.

Barasat/Jeerat has been commissioned but the Rajarhat(PGCIL)-Barasat/Jeerat 220 kV D/C line is still under implementation. To mitigate this N-1 problem, they have started strengthening of 220 kV Rajarhat-Newtown AA3D/C line with HTLS and will be completed by Dec, 2021. They have startedstrengthening of 220 kV Rajarhat-Newtown AA2 D/C line with HTLS and will becompleted by Jan, 2022. Subashgram (PGCIL) – Baraipur 220 kV D/c line isanti-theft charged from the Subhashgram side and the Baruipur substation isunder-construction which will be completed by Dec, 2021. Rajarhat(POWERGRID) to Barasat 220 kV D/c line section has been commissioned andthe same would be extended up to Jeerat by Dec, 2021.

For the summer peak scenario, the overload problem of the line is relieved bybus splitting of 220 kV New Town AA3 bus with New Town AA3 load & Rajarhatconnected at one split bus and EMSS and Subhashgram connected at the othersplit bus. Regarding 220 kV Suhashgram- EMSS D/C, SPS has beenimplemented which will operate if the current is increased beyond 1500 A.

5.5 220 kV Muzaffarpur (PG)-Hazipur D/C and 220 kV Hazipur-Amnour D/C lines: ERLDC stated that these lines are not N-1 compliant.

BSPTCL stated that a new 220/132 kV substation at Garaul (2x160 MVA) hasbeen planned and 220 kV connectivity planned at 220 kV Muzaffarpur (PG)-Garaul D/C will help with the issue. 220 kV Amnour- Muzaffarpur D/C line and220 kV Amnour-Digha D/C will also result in better reliability. Garaul will becommissioned by Dec 2021. It was also pointed out by BSPTCL that there has


542

been delay in commissioning of Motihari 315 MVA 3rd ICT due to failure while loading the downstream connectivity.

POWERGRID informed that due to some damage in the 132 kV bus, the ICTcommissioning was delayed and will be rectified by two months. Same wasnoted.

5.6 220 kV Gaya-(PG) -Bodhgaya D/C lines: ERLDC stated that these lines are not N-1 compliant.

BSPTCL stated that all the132 kV lines will be commissioned by Aug, 2021.LILO of 220 kV Gaya(PG)-Sonenagar D/C line at Chandauti has already beencharged. Due to problem faced in the entry of Bodhgaya, the LILO of 220 kVGaya (PG)- Chandauti D/C line at Bodhgaya is being delayed and will becommissioned by Oct, 2021. Same was noted.

5.7 ICT Constraints: Representative of CTU stated that the additional ICT at 400/220 kV Ranchi isyet to be allotted to implementing agency. Darbhanga 2x500 MVA ICTs will berelieved after commissioning of Saharsa S/s by Aug, 2021.

Regarding downstream network at Saharsa, BSPTCL stated that the 220 kVSaharsa-Khagaria D/C line will be commissioned by Oct, 2021. Also, due tosevere RoW issue and flood situation, the 220 kV Saharsa - Begusarai D/C linewill be completed by Dec, 2021. Same was noted.

5.8 Over voltage constraints: Regarding 400 kV Barh, it was opined that the issue being operational in natureand may be resolved at ERPC.

Regarding high voltage at 400 kV New Dubri, Pandiabili and Mendhasal,OPTCL informed that due to COVID situation, there has been a delay incommissioning of reactors at New Dubri, Mendhasal and Meramundali S/s andthe same will be commissioned by Sept, 2021.

Regarding 400 kV Kharagpur, Jeerat, Kolaghat, New PPSP, WBSETCL statedthat 4 nos. of 125 MVAR reactors have been planned at New Chanditala,Kharagpur, Durgapur and Gokarna with target completion schedule of Dec,2021. The already planned 2x125 MVAR bus reactor at New PPSP is yet to beawarded and will be commissioned by Aug, 2022.

Regarding 400 kV Bahrampur, Farakka NTPC and Sagardighi, ERLDC statedthat the overvoltage issue will be resolved if the Farakka TPS and SagardighiTPS absorb the reactive power as per their reactive capability curve. He alsoinformed that the overvoltage problem was observed at Behrampur side due toantitheft charging of 2nd ckt of 400 kV Bheramara-Behrampur D/C. Aftercharging from both sides the overvoltage problem will not be seen like before.ERLDC to take up this issue with ERPC.


543

It was suggested that CTU and ERLDC may study overload issues in ER gridand suggest remedial measures including planning of reactors. This will thenbe taken up in ERPCTP.

B. ToR 2(ii) – ASSESSMENT OF TRANSMISSION SYSTEM REQUIREMENTS IN NEAR,MEDIUM AND LONG TERM AND FORMULATE TRANSMISSION SCHEME

6. High loading on 220 kV Durgapur (PG) – Parulia (DVC) D/C line

6.1 Director(PSPA-II), CEA stated that in the 3rd meeting of ERPCTP, DVC hadstated that they will reconductor 220 kV Durgapur (POWERGRID) -Parulia (DVC) D/C with high capacity HTLS conductor. They had also informed that the LILO of 220 kV Parulia (DVC)-Waria D/C at DSTPS will be completed by Feb, 2021. WBSETCL had informed that the fault level at Bidhannagar is high and after the LILO of 220 kV Parulia (DVC)-Waria D/C at DSTPS, the loading at Bidhannagar-Waria D/C line will be high and the fault level at Bidhannagar will increase. They had asked DVC to delay the commissioning of LILO of Parulia (DVC)-Waria D/C at DSTPS after the commissioning of 3rd ICT at Bidhannagar substation i.e., after Dec 2021.

6.2 The matter was discussed in the Joint Study meeting held on 14.06.2021, it was agreed that till the commissioning of 3rd ICT at Bidhannagar, 220 kV Durgapur TPS – Waria TPS line may be kept open. After commissioning of 3rd ICT at Bidhannagar, 220kV Waria TPS – Bidhannagar (WBSETCL) D/c line can be opened. Further, WBSETCL may prepare long-term solution to the observed constraint like termination of Waria TPS – Bidhannagar line at some other place instead of Bidhannagar.

6.3 DVC stated that that in the meeting held in ERLDC, it was informed that till the 3rd ICT at Bidhanagar is commissioned, the tie line 220 kV Waria-Bidhanagar D/C will be kept in operational condition. After commissioning of ICT, the tie line will be opened and will be utilized on the emergency basis. The LILO of 220 kV Parulia (DVC)-Waria D/C at DSTPS is completed. Therefore, shutdown will be available for reconductoring of 220 kV Durgapur (POWERGRID)-Parulia(DVC) D/C with high capacity HTLS conductor which will be completed by Dec, 2021.

6.4 WBSETCL informed that the 3rd ICT at Bidhanagar will be commissioned by Dec, 2021. He also informed that the 220 kV Waria-Bidhanagar D/C line is old but important tie line for West Bengal. After opening this line, WBSETCL need another line for support and emergency use. He proposed 220 kV Asansol-Maithon (PG) D/C line which will be constructed by WBSETCL. WBSETCL was suggested to put up the proposal in the next ERPCTP meeting.


544

6.5 ERLDC stated that there are 3 ICTs at Durgapur(PG) but two outgoing lines. Further, loading on these lines have significantly reduced after commissioning of ICTs at DSTPS and drawal lines at 220kV. Therefore, they suggested WBSETCL to explore the possibility for taking in-feed from Durgapur(PG) which is very near to Bidhannagar.

6.6 After discussion, members agreed for the following: (a) Till the 3rd ICT at Bidhanagar is commissioned, the tie line 220 kV Waria-

Bidhanagar D/C will be kept in operational condition. After commissioningof ICT, the tie line will be opened and will be utilized in case of emergency.

(b) WBSETCL will identify implementation of new 220kV D/C line fromDurgapur (POWERGRID) to improve power supply scenario in Durgapurand Bidhan Nagar areas.

(c) WBSETCL to send their detailed proposal of 220 kV Asansol-Maithon (PG)D/C line to CEA for discussion in the next meeting of ERPCTP.

7. Non-compliance of N-1 contingency criteria on 220 kV Maithon-DhanbadD/C and 220 kV Maithon-Kalyaneshwari D/C line.

7.1 Director (PSPA-II), CEA stated that in the 2nd meeting of ERPCTP, ERLDC had raised the issue of high loading and non-compliance of N-1 contingency criteria on 220 kV Maithon-Dhanbad D/C and 220 kV Maithon-Kalyaneshwari D/C lines. With addition of 3rd ICT of 400/220 kV 500 MVA at Maithon, loading on these circuits will further increase. In the 3rd meeting of ERPCTP, DVC proposed the following scheme to reduce the power flow of these lines and relieving congestion:

(A) Establishment of 220KV infrastructure at existing Raghunathpur ThermalPower Station (RTPS) along with associated lines

Presently, RTPS is having two units (U # 1 & 2 :: 600 MW x 2) which areconnected to 400KV grid system. DVC proposed for:a. Establishment of 220KV side connectivity of 2 x 315MVA 400/220KV ICT

(already in service) along with 04 nos. of 220KV line bays for theconnectivity of item b.

b. D/C LILO of 220KV Chandrapura TPS – Kalyaneswari line to RTPS


545

(B) Construction of 400KV (AIS)/220KV (GIS) infrastructure at existing MejiaThermal Power Station (MTPS) along with associated linesDVC stated that MTPS (U # 1 to 6 :: 210 MW x 4 + 250 MW x 2, U # 7 & 8 ::500 MW x 2) is having no electrical connectivity between the 400 kV and 220kV system. DVC proposed for:

a. Installation of 2 x 315MVA 400/220KV ICT along with controlling bays atboth sides and 04 nos. of 220KV line bays for the connectivity of item b & c.

b. Shifting of 220KV D/C MTPS-A – Barjora Line from MTPS – A to MTPS – BSwitchyard

c. Tie connection between MTPS – A & MTPS – B at 220KV level.

d. 220KV S/C LILO of MTPS-A – Durgapur at Barjora substation.

7.2 He also stated that in the 3rd meeting of ERPCTP, ERLDC reported the constraint of high loading of 400 kV Maithon-B – Raghunathpur line therefore, the proposal of DVC may affect power flow in various lines and the fault level at Bidhan Nagar. The issue was discussed in the joint study meeting held on 14.06.2021 wherein it was agreed that the scheme proposed by DVC will resolve the issue of N-1 reliability criteria in 220 kV Maithon-Dhanbad D/C and 220 kV Maithon-Kalyaneshwari D/C lines.

7.3 DVC informed that the proposal will be completed in 18 months’ time (Dec, 2022).

7.4 Representative of CTUIL presented system studies wherein it was found that the DVC proposal also relieves the high loading issue of 400 kV Maithon-RTPS D/C line.

7.5 After deliberations, members agreed for the following Intra-state scheme to be implemented by DVC by Dec, 2022: (a) Establishment of 220kV infrastructure at existing Raghunathpur Thermal

Power Station (RTPS) along with associated lines.


546

(i) Establishment of 220kV side connectivity of 2 x 315MVA 400/220kVICT (already in service) along with 04 nos. of 220kV line bays for theconnectivity of item b.

(ii) D/C LILO of 220kV Chandrapura TPS – Kalyaneswari line to RTPS

(b) Construction of 400kV (AIS)/220KV (GIS) infrastructure at existing MejiaThermal Power Station (MTPS) along with associated lines.

(i) Installation of 2 x 315MVA 400/220kV ICT along with controlling baysat both sides and 04 nos. of 220kV line bays for the connectivity ofitem b & c.

(ii) LILO of 220kV D/C MTPS-A – Barjora Line at MTPS – B Switchyard.

(iii) 220kV S/C LILO of MTPS-A – Durgapur at Barjora substation.

Note : MTPS(A)-MTPS(B) 220kV D/C line may be normally kept open or close as per prevalent short circuit currents at 220kV level at Mejia-A and Mejia-B.

8. Line Reactor in Biharsharif – Lakhisarai 400kV D/c line and new busreactor at Biharsharif

8.1 Representative of CTUIL stated that Biharsharif – Lakhisarai 400kV line is about 89km and with 420kV, 50MVAr switchable line reactor at Biharsharif end, the line is about 84% compensated. Biharsharif – Sasaram 400kV line is about 210km and with 420kV 50MVAr switchable line reactor at Biharsharif end & 420kV, 63MVAr switchable line reactor at Sasaram end, the line is about 81% compensated. From studies it is observed that the said 2x50MVAr switchable line reactors at Biharsharif end are not required for line operation purposes. Upon splitting of Biharsharif 400kV bus, the section-A has 2x125MVAr + 1x50MVAr bus reactors and the section-B has 1x80MVAr bus reactor. In last one year, bus voltage in section-B is generally observed to be on higher side with maximum being about 422kV and average being 406kV. Further, the 50MVAr line reactor (proposed to be decommissioned) associated with Biharsharif – Lakhisarai ckt-2 is also on section-B. Thus, considering system voltages, proposed decommissioning of 50MVAr switchable line reactor and contingency of existing 80MVAr bus reactor, it is proposed to install a new 420kV, 125MVAr bus reactor at Biharsharif in bus section-B. POWERGRID has confirmed regarding availability of space for the same.

8.2 Chief Engineer (PSPA-II) inquired about the length of the Biharsharif (A)- Sasaram ckt-1 line on which one 50 MVAR switchable line reactor is connected.

8.3 Representative of POWERGRID stated that the length of the 400 kV Biharsharif (A)- Sasaram ckt-1 line is 210 km long. He informed that the 50 MVAR switchable line reactor was originally connected at 400 kV Biharsharif-


547

Lakhisarai line, but after bus splitting at Biharsharif, the reactor was shifted to bus section (A) to the line going to Sasaram.

8.4 It was observed that the 50 MVAR switchable line reactor at bus section (A) to the line going to Sasaram may be required for energising the line. If the line is energised from the Sasaram end, a rise of 12-14 kV is seen at the Biharsharif end. Therefore, the reactor of 50 MVAR is needed at Biharsharif end. The 125 MVAR bus reactor is needed in addition to the 2x50 MVAR switchable line reactor at Biharsharif for bus voltage control.

8.5 ERLDC presented the voltage duration curve at Biharsharif (A) and Biharsharif (B) and stated that the voltage level during the month of April, May and June2021 did not go beyond 420 kV. However, it was seen that the voltage wasseen going below 390 MW at few times at both the split buses of Biharsharif.

8.6 Chief Engineer (PSPA-II), CEA stated that as seen from the voltage duration curve shown by ERLDC, it is clear that the 50 MVAR switchable line reactors are needed at both the buses. Without them the voltage at both the split buses at Biharsharif will go up. Therefore, the issue has to be studied keeping in mind the Biharsharif and Varanasi configuration for reactors planning.

8.7 After deliberations, the issue was referred for joint study. Outcome of the studies will be put up before ERPCTP in next meeting.

9. Evacuation system of Teesta-IV HEP

9.1 Director(PSPA-II) stated that in the 2nd meeting of ERPCTP connectivity ofTeesta-IV HEP with ISTS was agreed as: a. LILO of Teesta-III HEP –Rangpo 400kV D/c (Quad) line at Teesta-IV HEP

generation switchyard – under ISTS.b. Establishment of 400kV Teesta-IV generation switchyard – by NHPC

9.2 He further stated that in 3rd meeting of ERPCTP, representative of ERLDC stated that at Teesta-IV switchyard, one and half breaker scheme may be implemented instead of double bus single breaker scheme. He also suggested that 400 kV LILO of Teesta-III – Rangpo D/C line to be terminated at Teesta-IV in such a way that in any contingency at switchyard, the line can be bypassed through Tie Circuit Breaker. The issue was discussed in Joint Study meeting held on 14.06.2021, in the meeting NHPC apprised that stated that due to space constraint, one and half breaker scheme and bypassing arrangement through isolator cannot be implemented. After the deliberations in the meeting, it was agreed that arrangement at LILO tower would be carried


548

out in such a manner that in case of major issue in Teesta-IV switchyard, the LILO can be bypassed in minimum time.

9.3 Representative of CTUIL stated that subsequent to grant of Connectivity on 01-01-2021, NHPC Ltd. signed the Transmission Agreement on 02/03/2021, butthey failed to submit the Construction Bank Guarantee as per CERCConnectivity Regulations within stipulated time even after multiple reminders.Accordingly, CTUIL vide letter dated 23-06-2021 has revoked the Connectivitygranted to NHPC Ltd. for its Teesta-IV HEP.

9.4 NHPC stated that they have not received Forest Clearance Phase-II for Teesta-IV. Therefore, their project timeline is not certain. They would again approachfor connectivity once the project advances.

9.5 Members noted the same.

10. Replacement of existing 50 MVAR LR of 400kV Maithon-Gaya-I with new50 MVAR LR (Natural Ester Oil) at Maithon S/s-reg.

10.1 Representative of ERPC stated that 400 kV 50 MVAR switchable LR with ester oil is first of its kind in India and had been undertaken as a R&D project by POWERGRID O&M wing. The 178th meeting of OCC of ERPC it was agreed to replace the switchable 50 MVAR LR of 400kV Maithon-Gaya-I line at Maithon end and the existing 50MVAR LR would be kept as spare Reactor.

10.2 POWERGRID informed that 400 kV 50 MVAR switchable LR with ester oil will be commissioning at Maithon in the line going to Gaya. This is a pilot project and currently there is no 400 kV LR with ester oil in the world and this will be a big milestone in the Indian power sector. Oil processing of this LR is different from the normal mineral oil processing. Shutdown of 400 kV Maithon-Gaya line is required for bushing erection of 400 kV 50 MVAR switchable LR with ester oil. The line length of 400 kV Maithon-Gaya line is 235 km and 50 MVAR switchable LR is at both ends of the line. POWERGRID also confirmed that there will not be any commercial implications for installing this 400 kV 50 MVAR switchable LR with ester oil.

10.3 Chief Engineer (PSPA-II), CEA appreciated the initiative taken up by POWERGRID for this Research and Development work and they welcome this pilot project. But, there are some regulatory, operational and commercial issues which needs to be addressed. For operational and commercial issues like outages and whether there will be O&M charges for the spare and the new LR with ester oil (twice O&M), POWERGRID may approach ERPC. For regulatory issues like regulatory life of the new Reactor, remaining regulatory life of the existing reactor which is being replaced, whether the existing reactor will be kept as regional spare or spare for Maithon and other issues, POWERGRID may approach CERC. He opined that the existing LR may be kept as spare for Maithon and not as a regional spare.


549

10.4 POWERGRID stated that the existing LR is 10-year-old and the new LR with ester oil will have regulatory life of 20 years. He also confirmed that O&M charges will not be levied for this project. They will also keep the existing LR as spare for Maithon.

10.5 Members agreed with the suggestion of CE (PSPA-II), CEA that POWERGRID may approach CERC for regulatory and commercial issues. Also for operational issues, POWERGRID may approach ERPC.

11. Restoration of 400 kV TSTPS-Meramunduli-2 to its original length.

11.1 ERPC stated that in the 177th OCC meeting it was discussed that 400KVTSTPS-Meramunduli-1 is of 56 km length and length of 400KV TSTPS-Meramunduli-2 is 86 km, during outage of Talchar HVDC pole differential loading at these circuits have been observed, due to which the circuit-1 becomes overloaded.

11.2 He explained that there are two ckts from Talcher to Meramundali i.e., 400KV TSTPS-Meramunduli1 and 400KV TSTPS-Meramunduli-2. 400KV TSTPS-Meramunduli-2 was LILOed at Angul but it is currently working as 400KV TSTPS-Meramunduli-2. Subsequently, a flexible arrangement was made in which in case of any contingency, the LILO portion at Angul will be operational and the line will become 400KV TSTPS-Angul and 400KV Angul-Meramunduli-2. Due to this LILO arrangement, the length of the 400KV TSTPS-Meramunduli-2 has become 86 km from original 56 km. In the normalconditions, the LILO portion at Angul is bypassed. The problem of differentialloading in 400KV TSTPS-Meramunduli-1 (56 km) and 400KV TSTPS-Meramunduli-2 (86 km) becomes a matter of concern when 400KV TSTPS-Meramunduli-1 gets overloaded. He proposed for bypassing the LILO at Anguland make the length of the circuit-2 to original 56 km.

11.3 OPTCL stated that this LILO portion at Angul as circuit-2 was constructed for enabling Odisha to draw its share from generators pooled at Angul. However, this resulted in increase in fault level at Meramundali S/s. They are in process of establishing a 125 MVAR reactor and after the decommissioning of TTPS (460 MW), the fault level at Meramundali has come down. Further, the 400 kV lines can be diverted to 400kV Meramunduli-B which is nearing completion (January, 2022). This will also contribute in lowering the fault level at Mermundali S/s and thereafter, the LILO portion at Angul can be bypassed and line may be shorted at the LILO point. They also need to do system studies to see the effect on the voltage profile and fault level after opening of LILO at Angul.

11.4 ERLDC stated that from the operational point of view, the LILO at Angul gives the reliability and flexibility to the system as in case of any emergency like outages, the Angul can be used as the source to supply power to Odisha grid.


550

They opined that the existing system of LILO at Angul may be kept for emergency use.

11.5 After deliberations, the ERPC proposal could not be agreed.

12. Arrangement for 33 kV Power Supply to Dulanga Mines from DarlipaliSTPP of NTPC.

12.1 ERPC informed that 178th meeting of OCC of ERPC referred the issue of arrangement for 33 kV Power Supply to Dulanga Mines from Darlipali STPP of NTPC to ERPC-TP. NTPC have informed in the meeting that at the mining point of Dulanga there is no connectivity of DISCOM. Therefore, they want to draw power from nearby Darlipalli STPP as a consumer of GRIDCO. GRIDCO have already given their NOC for connection to NTPC in consumer mode. This drawl will be from Darlipalli station. Transformer and the drawl will be treated as GRIDCO drawl from Darlipalli STPP. NTPC will draw power from one 33kV feeder from Darlipalli and the drawl will be booked in the GRIDCO account.

12.2 ERLDC stated that this connectivity will ensure the reliable supply to captive mine Dulanga of Darlipalli STPP. Drawl may be treated that of GRIDCO. This line will be treated as tie line.

12.3 CTUIL stated that Darlipalli STPS 765/132/33 kV station is connected to the ISTS system and NTPC is free to use its own power for its internal consumption. Connectivity of 1600 MW have been granted to Darlipalli STPP through 765 kV line Darlipalli-Jharsuguda D/C line. Also, nowhere in the connectivity intimation from NTPC, it has been mentioned that Darlipalli have separate drawl arrangement through 33 kV feeder. GRIDCO has also taken LTA of 748 MW from their share of Darlipalli STPP. If GRIDCO gets connected to 33kV feeder of Darlipalli STPP for Dulanga mines, they will not have to pay ISTS charges as drawal quantum may get adjusted in the LTA quantum.

12.4 NTPC stated that they need a reliable power supply for Dulanga mines from Darlipalli STPP. It will be ensured that the feeder to Dulanga mines will be radial in nature and it will not be extended to any other area. NTPC will be responsible for the payment of the drawl which may be treated as GRIDCO drawl.

12.5 Chief Engineer (PSPA-II), CEA stated that Darlipalli cannot be connected to distribution system as Darlipalli, a central generating station is already connected to ISTS system. He also stated that OCC forum should only discuss the operational issues and the connectivity issues like this should only be discussed in ERPCTP meeting.

12.6 He suggested that, for NTPC to draw power form 33 kV feeder of Darlipalli STPP, they should apply for revised connectivity to CTUIL. After revised connectivity, the 765/132 kV and 132/33 kV transformer becomes part of the generating station and the 33 kV bus notionally becomes the 2nd level for evacuation system. Then notionally, it can be treated to be connected to


551

OPTCL i.e., STU of Odisha which may provide power to DISCOM of Odisha for Dulanga mines.

12.7 CTUIL stated that dual connectivity of ISTS and states for same capacity is not allowed as per regulations.

12.8 OPTCL stated that they are implementing an upcoming lipdipada S/s which is around 15 km from these mines and connectivity can be given from this substation.

12.9 Members did not agree for proposed drawl arrangement at 33 kV level for Dulanga mines and suggested that NTPC may approach OPTCL for connectivity and drawal of power for its Dulanga mines from the upcoming Lipdipada (OPTCL) substation to meet their mining load.

13. ISTS connectivity for Railways at Sasaram (Pusauli)

13.1 Director(PSPA-II), CEA stated that Railways has approached CEA for gettingISTS connectivity at Sasaram (Pusauli) for their Eastern Dedicated Freight Corridor project. The issue was discussed in 19th Standing Committee on Power System Planning of Eastern Region held on 01.09.2017 where Eastern Region constituents had raised concerns over non-utilization/underutilization of assets created by states and sub-optimal utilization of RoW & space at ISTS substations. Thereafter, an agenda was forwarded by Railways on 05.07.2019, for discussion in the 2nd meeting of ERSCT to be held on the same day. In the meeting representative of ERPC, BSPTCL, OPTCL, DVC and West Bengal stated that the issues raised by them in the previous meetings, like underutilization of transmission assets, are yet to be resolved, therefore they raised objection for giving ISTS connectivity to Railways in Mughalsarai – Howrah and Ludhiana – Sonnagar routes.

The issue was further discussed in 1st meeting of Eastern Region Power Committee (Transmission Planning) held on 14.02.2020 wherein Railways presented their response to the concern raised by ER constituents. During discussion on the subject certain legal, regulatory, operational and transmission planning related issues were raised.

Subsequently, Ministry of Railways vide letter dated 17.03.2021 has furnished para-wise comments on the issues raised in the 2nd meeting of ERPCTP, and requested CEA to resolve the issue of ISTS connectivity at Sasaram (Pusauli) for commissioning of EDFC (Eastern Dedicated Freight Corridor) as per schedule. Railways in their letter dated 17.03.2021 (copy enclosed at Annexure-VI) have mentioned that

“4. …….In this regard, it is clarified that Indian Railways constructs the ISTS/STU connectivity lines as electric supply lines under provisions of Indian Railways Act, 1989 to serve its own loads.”


552

13.2 He also added that a meeting was held with CTUIL, NLDC, ERLDC and Railways on 07th June, 2021 under chairmanship of Member (PS), CEA. In the meeting it was opined that Railways being government organization and having responsibility to construct electricity supply line under Railways Act, they may not require to submit connectivity application under regulations of CERC. However, other requirements of connectivity like equipment information, connectivity agreement etc need to be signed by Railways as per Central Electricity Authority (Technical Standards for Connectivity to the Grid) Regulations, 2007 and amendments thereof.

13.3 Railways stated that Eastern Dedicated Freight Corridor project is a Greenfield project and is to be commissioned by 2022. He requested that connectivity from ISTS may be allowed at the earliest.

13.4 CTUIL stated that though the Railways need not apply for connectivity, however, ICT loading at Sasaram where Bihar is drawing power needs to be seen. If adequate margin is available for Bihar keeping in mind their load growth, this proposal may be agreed for Railways to draw power from Sasaram.

13.5 Member Secretary, ERPC stated that the Sasaram (Pusauli) was originally designed for Bihar state to cater the load growth of Bihar. If there is spare capacity at Sasaram (Pusauli) after satisfying the requirement of Bihar state, then Railways may be given connectivity at Sasaram (Pusauli).

13.6 Bihar stated that Railways load projection is 20 MW which will increase to maximum 60 MW by 2030. As the thermal limit of 220 kV D/C line is around 400 MW, giving connectivity from two 220 kV bays for a load of 20-30 MW of Railway is underutilization of the national asset. Also, the space available at Sasaram (Pusauli) is limited and it cannot be extended for constructing additional bays. If two bays are blocked by Railways for 20-30 MW of load, Bihar will not be able to connect to Sasaram (Pusauli) in future to cater to the demand due to load growth. To save the blocking space at ISTS S/s and to avoid underutilization of 220 kV bays at Sasaram (Pusauli), Bihar has already proposed for connectivity from their newly constructed Karmnasa S/s which is near to Sasaram. They have assured that Railways will be given uninterrupted reliable power to Railways from Karmnasa.

13.7 Member (PS), CEA stated that in case of connectivity to Railways from Kramnasa the power drawl by railway would be through 220 kV and the loading would be around 20-30 MW. As such the utilisation of the bays would remain the same even it is through Karamnasa. He stated that Railways being government organization and having responsibility to construct electricity supply line under Railways Act, the connectivity to Railways cannot be denied. Also, Railways have commercial reason for not taking power from Bihar.


553

13.8 Bihar stated that Railways can construct electric supply lines as they are empowered from Railways Act. But connecting with ISTS needs to be agreed in ERPCTP. Further, blocking of 220 kV bays at Sasaram (Pusauli) which was constructed to cater the demand of Bihar for a load of 20-30 MW is gross underutilisation of assets.

13.9 Railways stated that their ISTS connectivity will not affect Bihar. He added that they have sought for ISTS connectivity to save the STU charges which would be levied if they are connected to state network. Also, Railways have already been granted connectivity to ISTS in Abdullahpur, Auraiya, Naini and Dadri.

13.10 NLDC stated that a formal application for connectivity has not been made to CTUIL. The connection agreement and other technical details are pre-requisite for any connection to ISTS. CTU is already signing connection agreement elsewhere, Railways should have already applied to CTUIL directly. He asked that whether DFCCIL is a separate entity or Railways would be the ultimate consumer of power or Railways.

13.11 CTUIL stated that CERC in its order in petition no. 197/MP/2015 dated 05-11-2015 has mentioned that the “42. … Indian Railways is an authorized entity to distribute and supply electricity in connection with the working of the Railways under the Railways Act, the petitioner shall be entitled for grant of open access in connection with the working of Railways as per provisions applicable to distribution licensee”. As such under CERC Connectivity Regulations, 2009 and its amendment thereof there is no provision for a distribution licensee to apply for Connectivity in ISTS. Further, it has been observed in the order that “40. … so far as Indian Railways are concerned, they will be governed by the provisions of the Railways Act for constructing transmission lines and distribution installations for the purpose of supply of power to the Railways without having to take any licence from the appropriate Commission for transmission or distribution of electricity. In other words, the Indian Railways can be treated as authorized entity under the Railways Act for carrying out transmission and distribution activities for ensuring supply of power in connection with working of the Railways.”. Thus, connectivity application may not be required from Indian Railways. However, before physical connection with ISTS the Connection Agreement with Railways can be signed. Also, Railways will have to apply separately for transmission access after getting connected to ISTS.

13.12 Railways stated that DFCCIL is a CPSU fully owned by Railways to carry out the freight business. Railways have an agreement with DFCCIL that, Railways will pay the traction charges on behalf of DFCCIL and the network of DFCCIL will be used by Indian Railways. The complete revenue of DFCCIL goes to Indian Railways.

13.13 Chief Engineer (PSPA-II), CEA stated that as per the communication received, the connectivity is being sought by Railways to meet their own load. Therefore,


554

if connectivity is agreed by this committee, all the contracts and connection agreement will be between Railways and CTUIL and not with DFCCIL.

13.14 Bihar stated that at present N-1 criteria is not getting fulfilled at Sasaram and a study need to be done to see the future load growth of Bihar and its effect on Sasaram. He added that load of Bihar is growing by CAGR of 12%. After charging of Karmnasa New S/s, the demand will further increase by 40-60 MW. Buxar TPS take 4-5 years’ time for commissioning. Bihar stated that if the power is needed immediately for DFCCIL, then it should be taken from Karmnasa. He said that it has come to their notice that POWERGRID has already started construction of line for Railways from Sasaram without taking any approval.

13.15 CTUIL stated that Sasaram (Pusauli) has 2x500 MVA ICTs in which present Bihar load is about 400-450 MW. Therefore, 30-50 MW margin is available at Sasaram. Further, it was seen from the studies that after commissioning of Buxar TPS, the Bihar’s drawl of power from Sasaram (Pusauli) gets reduced. In order to meet the future drawl requirements of the state, additional substation can be planned in the area.

13.16 Member (PS), CEA stated that Bihar may take power from Karmnasa to fulfil its growing demand.

13.17 Bihar stated that the connectivity in Western Region from Raipur was given to Railways as a bulk consumer. In this case also, Railways does not have any legal right to claim for ISTS connectivity. As DFCCIL is a separate entity, any other entity may come in future and claim to have legal right for ISTS connectivity through Railways even though their load requirement does not fall under bulk consumer and DFCCIL is not a deemed licensee. This will start a wrong trend in future. Therefore, ISTS connectivity should be denied to Railways for 20-30 MW of load of DFCCIL. He also stated that for the sake of accommodating Railways, if new system would be planned for Bihar, then it will be an unnecessary expenditure and a burden of all states/discoms.

13.18 Railways stated that they are already having ISTS connectivity from Dadri, Auriya and Naini in Uttar Pradesh. The UPSEB went to court and in 2021, Supreme Court ordered in favour of Indian Railways and stated that Indian Railways have every right to construct its transmission line for distribution and transmission of electricity for its own use. Presently, they are connected to STUs as well as ISTS in thirteen (13) states.

13.19 Bihar stated that they have been paying charges for the ICTs installed at Sasaram keeping in mind the future load growth of their state.

13.20 Railways stated that they will be paying the ICT charges as per applicable regulations.


555

13.21 CTUIL confirmed that the charges of the ICTs are distributed in ratio of the bays. Therefore, the charges of ICTs will be shared by railways after getting connected and Bihar will be relieved of ICT charges.

13.22 Chief Engineer (PSPA-II), CEA summarised the discussion as following: (1) It appears that as per extant laws/regulations, the Railways need not apply

for connectivity to CTUIL. However, they may have to sign connectionagreement with CTUIL, if agreed by ERPCTP.

(2) Sasaram S/s has two 400/220 kV ICTs and there is no space for 3rd ICTas told by Bihar and POWERGRID. Also, six (6) number of 220 kV bayscan be accommodated in Sasaram, out of which, four (4) bays are beingused by Bihar and remaining two are being proposed for connection toRailways.

(3) Bihar has stated that as the load of Railways is 20-30 MW, it will be thewastage of the already limited space.

(4) Bihar under the new regulation will pay for the ICTs and outgoing baysprovided Railways applies under LTA in which case the charges will bedivided in the ratio of bays.

(5) ISTS is created as a common facility for all and all have equal rights.Railways and Bihar and all other countries are free to fulfil and safeguardtheir commercial interests.

(6) Bihar’s present drawl is around 450 MW from the 2x500 MVA ICT atSasaram and as such presently N-1 compliance is met. If Railways getconnected, Bihar cannot draw more power from their S/s. This situation,however, may improve with commissioning of Buxar TPS in future (2025-26). Bihar has also suggested that a load flow study may be done to seethe effect of Railways getting connected at Sasaram along with loadgrowth of Bihar.

(7) The decision of the committee should be through consensus as perpractices.

13.23 Member (PS), CEA stated that the Bihar has four (4) lines from Sasaram and loading of 450 MW. Therefore, with N-1 reliability, Bihar can only draw up to 50 MW more from this substation as space for expansion is not available. If Railways connects to Karamnasa then also the lines will be underutilized. Further, Bihar does not have any immediate power requirement and there is some capacity available for future load growth. If any requirement arises in near future, system will be planned to cater the load growth of Bihar. He suggested that connectivity to Railways at Sasaram may be given.

13.24 As suggested by Member (PS), CEA, the ISTS connectivity for Railways from Sasaram (Pusauli) through 220 kV D/C line along with associated line bays at


556

both ends, to be implemented by Railways was agreed on the following considerations:

a) Railways is government organisation having responsibility to constructelectricity supply line under Railways Act.

b) They may not require to submit ISTS connectivity application underConnectivity Regulations of CERC.

c) Other requirements of connectivity like equipments information, connectivityagreement etc need to be signed by Railways with CTU as per CentralElectricity Authority (Technical Standards for Connectivity to the Grid)Regulations, 2007 and amendments thereof and CERC ConnectivityRegulations.

14.5 CTU vide letter dated 01.01.2021 had intimated about the connectivity granted to NHPC for its upcoming Teesta-IV HEP (520MW) through LILO of Teesta-III HEP – Rangpo 400kV D/c (Quad) line at Teesta-IV HEP (to be built under ISTS). Subsequent to grant of Connectivity, NHPC Ltd. signed the Transmission Agreement on 02/03/2021 for taking up the system under ISTS, but they failed to submit the Construction Bank Guarantee (26 Cr.) as per CERC Connectivity Regulations within stipulated time even after multiple reminders. Accordingly, CTUIL vide letter dated 23-06-2021 has revoked the said Connectivity granted to NHPC Ltd. for its Teesta-IV HEP.

15. Interim connectivity to generation projects in ER through LILOarrangement

15.1 Director (PSPA-II), CEA informed that in some cases generation projects were commissioned ahead of the 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. 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 generators are still connected through LILO arrangement. CERC in its order dated 07-102015 on Petition No.112/TT/13 and dated 28-09-2016 in Petition no. 30/MP/2014 has directed that the interim (LILO) arrangement has to be removed.

Additional Agenda

18. Revised Connectivity of GMR-Agenda item from OPTCL.

18.1 Representative of OPTCL stated that in the 18th meeting of the StandingCommittee on Power System Planning of Eastern Region held on 19.08.2016, the connectivity of GMR was approved as part of Intra-State system with the scope of work including shifting of GMR-Meramundali 400 kV S/C line from Meramundali to Meramundali-B and disconnection from Meramundali-A.

18.2 He proposed a LILO connectivity of GMR-Meramundali at Meramundali-B so that in case of outage of either Meramundali or Meramundali-B, GMR will be able to export power to the other substation. Under normal operating condition, Meramundali-A will not be connected to Meramundali-B. But in a worst case scenario, i.e. during the outage of Meramundali-B substation, the GMR will be connected to Mermaundali-A by jumpering from outside Meramundali-B s/s.

18.3 Chief Engineer (PSPA-II), CEA opined that Mermundali-A and Mermundali-B are not to be connected in normal circumstances and only to be used in case of outage of Mermundali-B. Therefore, OPTCL may Loop-In from GMR- Meramundali-B and the Loop-Out from Meramundali-B to Meramundali-A may be omitted. This would result saving of one bay at Meramundali-B and in case of eventuality at Meramundali-B, the S/s could be by-passed by jumpering arrangements at LILO point.

18.4 Members agreed with the suggestion of Chief Engineer (PSPA-II), CEA.


561

19. LILO of 132 kV Sahupuri (220 kV)- Karmnasa (Bihar) Ckt-II at 132 kVChandauli (Chandauli) S/s-Agenda item from UPPTCL.

19.1 Representative of UPPTCL stated that in the 3rd NRPCTP meeting held on 09.02.2021, members had agreed to the proposal of UPPTCL for LILO of 132 kV Sahupuri (220 kV)-Karmnasa (Bihar) ckt-II at 132 kV Chandauli S/s. It was suggested to UPPTCL to get the proposal ratified in ERPC(TP) meeting as 132 kV Sahupuri (220 kV)-Karmnasa (Bihar) is an inter-regional line. He added that UPPTCL has also sought NOC from BSPTCL which has not yet been granted.

19.2 He further stated that 132 kV Chandauli (U.P.) S/s is being fed by LILO of 132 kV Sahupuri (220 kV)-Karmnasa (Bihar) ckt-I. He informed that generally, there is no power flow at 132 kV Sahupuri (220 kV)-Karmnasa (Bihar) ckt-II. In emergency, UPPTCL can withdraw only 15-20 MW power from Karmnasa (Bihar) at 132 kV S/s Chandauli (U.P.). To ensure reliable power supply to 132 kV S/s Chandauli, LILO of 132 kV Sahupuri (220 kV)-Karmnasa (Bihar) ckt-II is proposed by UPPTCL.

19.3 Representative of BSPTCL stated that they have no objection on implementation of the proposal by UPPTCL.

19.4 The proposal was agreed for the proposal of UPPTCL.

20. Connectivity of 400/220/132 kV, Daltonganj of PGCIL to newly constructed220/132/33 KV (2x150+2x50) MVA Grid Substation Chatra (Itkhori) of JUSNL-Agenda item from ERPC

He also informed that Chatra (Itkhori) GSS is to be energized from 440/220/132 GSS, Latehar through 220 kV Chatra-Latehar transmission line. He further stated that the construction activity of 400/220/132 kV GSS, Latehar which is being done by M/s POWERGRID through JCP Project is in progress but it may take time in completion.

20.2 For early commissioning of constructed 220/132/33 KV (2x150+2x50) MVA GSS Chatra (Itkhori) of JUSNL, he proposed for making connectivity from 400/220/132 kV, Daltonganj of POWERGRID through newly constructed 220 kV Chatra- Latehar Transmission Line & existing 220 kV Latehar- Daltonganj (PG) Transmission line.

20.3 The schematic diagram of proposal is given below:

20.4 Chief Engineer (PSPA-II), CEA asked about operation of 220 kV Daltonganj-Latehar line and length of line after the arrangement.

20.5 Superintending Engineer, ERPC stated that 220kV Latehar to Daltonganj transmission line is yet to be commissioned, 400kV Latehar S/s is not ready. He also stated that the said transmission line is idle charged from 132kV Latehar S/s and presently not connected to Daltonganj S/s. He further stated that 220/132/33 KV Chatra S/s (JUSNL) is ready since last 4 years and being back charged with 33kV, therefore temporary connectivity at 220kV level from location no. 7 of 220 kV Latehar-Daltonganj line may be considered.


563

20.6 Representative of JUSNL stated that the total length of line from Daltonganj to Chatra would be 143 km.

20.7 On enquiry by Director (PSPA-II), CEA, representative of JUSNL stated that both the circuits would be connected to Chatra.

20.8 After deliberations, following were agreed: (a) The existing 220 kV Latehar- Daltonganj (PGCIL) D/C line will be

disconnected from Latehar end (Location no.-7) and connected to 220 kVD/C Latehar-Chatra (Location 72/1) to form 220 kV Daltonganj-Chatra(JUSNL) D/C line as temporary arrangement for charging of 220/132/33 KV(2x150+2x50) MVA Grid Substation Chatra (Itkhori) JUSNL.

(b) The original planned arrangement need to be restored with commissioningof 400/220/132 kV GSS, Latehar.

21. To provide 2nd source connectivity to the existing Grid Sub-station(GSSs)-Agenda item by BSPTCL

21.1 Representative of BSPTCL stated that various 132/33 kV GSSs of are operating in radial mode with single source connectivity. In case of outage of these sources, the area becomes powerless for a longer period causing inconvenience to the public. For supply of stable and quality power and to fulfil N-1 criteria also he proposed to provide 2nd source connectivity to 20 numberof substations.

21.2 Chief Engineer (PSPA-II), CEA stated that the agenda was received very late and could not be examined/studied.

21.3 It was agreed that the agenda will be discussed in next meeting after Joint Studies.

22. To provide 2nd circuit stringing of the existing GSSs- Agenda item by BSPTCL

22.1 Representative of BSPTCL stated that there are thirteen 132/33 kV GSSs of BSPTCL are operating with single circuit of transmission lines strung over double circuit towers (DCSS). In case of outage of these single circuit lines, the area becomes powerless for a longer period causing inconvenience to the public. For supply of stable and quality power and to avoid power interruptions, he proposed to string second circuit on these transmission line towers.



23. Evacuation of Power from Kajra & Pipainti Solar Plants-Agenda item by BSPTCL

23.1 Representative of BSPTCL stated that BSP(G)CL is constructing two solar plants viz. Pirapanti and Kajra, of 250 MW each. He further stated that to

ANNEXURE-V

Operational constrains faced in Eastern Region by the system operator during Q3 & Q4 of 2020-21 are given below:

A. Transmission line constraints

Sl. No Corridor Description of the constraints Decision/ deliberation

1 220 kV Buddhipadar-Lapanga D/C, 220 kV Buddhipadar Vedanta D/C and 220 kV Rourkela-Tarkera D/C

These lines are not N-1 compliant. This issue has been observed with very high injection from Vedanta Captive plant ( 250-300 MW) on a persistent basis. Further, it has been enhanced with the retirement of 220 kV TTPS power plant in the Orissa system.

Also, parallel bunching of 400/220 kV ICTs at Rourkela ( 2 X 630 MVA) have led to a low impedance path which is leading to higher loading on only evacuation lines i.e. 220 kV Rourkeal-Tarkera D/C planned from the Rourkela substation.

Cascaded Event in 220/132 kV Budhipdar S/S causing complete blackout: On 08-04-2021, cascaded tripping of 220 kV lines from Buddhipadar occurred causing a complete blackout of the substation indicating the N-1 reliability issue at Buddhipadar. In this Vendanta island also got collapsed.

After the discussion at ERPC level, ERPC may send the proposal with recommendations to include in the next meeting of ERPCTP.

2 220 kV Waria-Bidhan Nagar D/C

220 kV Bidhan Nagar (Durgapur) is a Major load centre in West Bengal Area. With nearby generating plant of DVC feeding these load due to low impedance path is resulting in higher loading of the220 kV Waria-Bidhan Nagar D/C. In addition to these, the 220 kV Bus at Bidhnagar is operated in split mode due to high fault level by opening of 220 kV bus coupler. Further, the 400/220 kV Waria-Parulia (D/C) has been made LILO at 400/220 kV DSTPS and one of the 400/220 kV

ICT are in service making these circuits a low impedance path and thus their overloading.

3 400 kV B Maithon - RTPS

During high generation at Raghunathpur TPS (both units in service) and low generation at MPL, the loading of 400 kV Maithon B- RTPS approaches its thermal limit as it provides a low impedance path being a short line (40 km) to Maithon which is a load centre.

Included in Agenda Item no. 7

4 220 kV Patna-Sipara T/C

There are three 220 kV lines between Patna (POWERGRID) and Sipara (BSPTCL) S/s. Major loads of Patna are fed from 220 kV Sipara substation. The length of the line is extremely short (less than 500 m). Further, Sipara is connected with Khagaul as well as to Fatuah at 220 kV level and is partly feeding these loads also. This is leading to higher loading of 220 kV Patna-Sipara T/C and violation of N-1 security criteria constraint for most of the time.

Reconductoring work is expected to be completed by July, 2022

5 220 kV Durgapur (PG) – Parulia (DVC) D/C

Parulia (Durgapur) is a major load center in the DVC control area. Due to decommissioning of DVC units (at Bokaro-B and CTPS) and low generation from internal plants particularly at Mejia and Waria, the load of Parulia and nearby area is practically met through importing large quantum of power from Durgapur substation of PG through 220 kV Durgapur(PG)-Parulia(DVC) D/C. This resulted in very high loading of the above lines and even crossed the N-1 security limit. Besides, it is observed from studies as well as established through trial operation that these loading further increase with 400 kV bus split operation of Durgapur (PG) and third 400/220 kV ICT operation at Durgapur which has

already been taken into service from June 2019.

6 220 kV Maithon-Dhanbad D/C and 220 kV Maithon-Kalyaneshwari D/C

High loading of 220 kV Maithon-Dhanbad D/C and 220 kV Maithon-Kalyaneshwari D/C is observed due to 1. Less generation at CTPS2. Low/ NIL generation at Bokaro-

B3. Less generation at Koderma

With the commissioning of 3rd Maithon ICT of 500 MVA. Loading has further increased on these circuits due to low impedance path and nearness to the load centre.

Included in agenda point no. 7.

7 220 kV Rajarhat- Newtown D/C and 220 kV Subhasgram-EMSS D/C

These lines are not N-1 compliant. In this qtr, 220 kV Shubhasgram-EMSS loading is low however it is more during the summer season.

1. Commissioning of Rajarhat(POWERGRID) – New TownAA2 220 kV D/c, Rajarhat(PGCIL) – Barasat/Jeerat 220kV D/c and Subashgram(PGCIL) – Baraipur 220 kV D/c.

2. Load trimming scheme hasbeen implemented by CESC for(n-1) contingency on 220 kVSubhasgram-EMSS D/C.

1 400/220 kV Ranchi 2 X 315 MVA ICTs

With Low generation at Tenughat, increased load of JUSNL and drawal by WBSETCL from 220 kV Chandil-STPS, loading of 400/220 kV Ranchi ICTs exceeded the (n-1) security limit

Additional ICT at 400/220 kV Ranchi was agreed in 3rd meeting of ERPCTP.

2 400/132 kV 2 X 200 MVA Motihari ICT

Motihari ICTs are feeding to loads of North Bihar as well as to Nepal through 132 kV Raxaul-Parwanipur circuits. Due to the increase in Load in North Bihar these ICTs do not satisfy N-1 Criteria.

Status noted.

Sub: ISTS connectivity for Railways ::.t Sasaram Pasauli. Ref: (i) This office letter of even no. dt. 30.09.20.

New Delhi, Dated: 17.03.2021

(ii) DFCCIL Letter No. HQ/EL/Tra:1srnission Line/Pt IV dt. 27.07.20.(iii) Minutes ofist ERPCT meeting held on 14.02.20.(iv) Rly Bd Letter No. 2012/Elect(G)/150/I Pt-II dt. 03.07.19.

Earlier, vide letter under reference (i), CEA was requested to resolve the issue of ISTS connectivity at Sasaram (Pasauli) for commissioning of EDFC (Eastern Dedicated Freight Corridor) project. This issue was discussed during 1st ERPCTP meeting held on 14.02.20. However, the work is held up due to certain issues pe1taining to deemed licensee status of Indian Railways (IR), loading of investment cost on States, under-utilization of state assets etc. and insistence on connectivity with STU at Kannnasa by other stake holders viz., BSPTCL, POSOCO. It is pe1tinent to mention that progress of this prestigious project is being monitored by PMO and recently Hon'ble PM has inaugurated part section from New Khurja to Bhaupur (near Kanpur) of EDFC. Para-wise comments of IR 011 the issues discussed in the 1st meeting of ERPCTP, is attached as Annexure-A.

2. EDFC extends from Sahnewal in Punjab to Dankuni in West Bengal and is planned with 25KV OHE. Indian Railways, as deemed licensee under the Electricity Act 2003, is drawing tractionpower in the States of Punjab, Haryana, U.P., Bihar and DVC area through the grid connectivity withrespective STUs. In U.P, Traction Substations (TSSs) in Dadri - Naini section are connected to CTUand is drawing I 05MW power at UP-ISTS.

3. Accordingly, Dedicated Freight Ccrridor Corporation of India Ltd. (DFCCIL) had plannedISTS connectivity at Abdullapur, Meerut and Sasaram (Pasauli) inconsonance with the existingconnectivity status. ISTS connectivity at Abdullapur and Meerut have already been granted;however, ISTS connectivity at Sasaram (Pasauli) is yet to be granted.

4. It is pertinent to mention that requircJ infrastructure for connectivity with ISTS at thesepoints is owned and funded by Indian Railways and works are being executed by PGCIL. Necessarycontracts were awarded to PGClL in 2016. In this regard, it is clarified that Indian Railwaysconstructs the ISTS/STU connectivity line<; as electric supply lines under provisions of IndianRailways Act, 1989 to serve its own loads. Indian Railways is seeking ISTS connectivity at Sasaram(Pasauli) as a Deemed Licensee under Electricity Act, 2003 to supply power to its own loads.

5. In view of above, it is requested to resolve the issue of ISTS connectivity at Sasaram(Pasauli) at �e earliest so that EDFC couk be commissioned as per schedule.

Annexure-A

Para�wise comments on minutes of ER.PC meeting are as below.

23.1 Noted. Railway has been requesting for ISTS connectivity at Pasauli since 2016.

23.2 As such the concern seems to be generally stated and without facts. It is already mentioned that the ISTS connectivity at Pasauli was planned and contract awarded to PGCIL: :1 is understood that assets created by states had not taken into nccount the anticipated traction load from DFCCIL, so the question of under utilization of already created transmission assets does not arise.

23.3 No comments.

23.4 BSPTCL is not placing correct facts about Karmnasa. The fact is that Karmnasa was not commissioned on the date of meeting (14/02/2020) and it is not yet commissioned whereas Railways had planned connectivity for ISTS PascJuli since 2016. Rly provides Double circuit transmission lines for carrying additional load as well as enhanced reliability as traction load is essential in nature and full/partial failure in incoming transmission line may land to regulation of railway traffic. DFCCIL is targeted to be commissioned in 2021 and capacity created shall be fully utilised in due course. Transmission line is being constructed by Railway with its own funds · and for its dedicated use; BSTPCL's concerns regarding underutilization cf national assets are not tenable.

23.5 PGCIL's view supports Railway's contention.

23.6 No comments.

23.7 Indian Railways is a Deemed Licensee for transmission and distribution of electricity in connection with working of Railways. Pl see detailed explanation at Annexure-1. The subject tr.ansmission line is meant for dedicated use of Railways and can'tb.e used by state or any other entity.

23.8 Transmission line is being constructed by Railways own funds and question of loading its investment cost on states does not arise.

23.9 Railway is making investment in ISTS connectivity for its traction load in view of long term financial benefits and improved reliability.

23.10 Same comments as in para 23.9

23.11 Existing transmission network of Railways from Dadri to Naini (approx. 600km) has CTU connectivity at three locations i.e. Dadri, Auraiya and Naini and this system is working to Railway's satisfaction since long. A fourth CTU connectivity at Pasauli wi!I in fact add to the reliability of this transmission network. Railway has already planned double circuit lines for improved reliability. Instances of tripping are experienced with STU connectivity as well. In fact, as per Railways experience is that CTU connected supply is more reliable than STU connected.

23.12 Connectivity with ISTS is fim:mcially advantageous as compared to STU connectivity as STU ttansmiss!on and other charges levied by state are saved.

23.13 Indian Railways is seeking connectivity as a deemed transmission Licensee. Indian Railways is a deemed Licensee for transmission and distribution of electricity in connection with working of Railways as per provisions in Railway Act 1989 and IE Act 2003. Hon'ble Supreme Court in the case of General Manager, Northern Railways Vs Chairman, Uttar Pradesh State Electricity Board and Others (2012) had stated that the Railways is governed by Railways Act, 1989. It held that IR is an authorized entity under the Railways Act to undertake transmission and distribution activities in connection with the working of the Railways. Central_ Ele.ctricity· Regulatory Commission vide its Order dated 05.11.2015 passed in Petition No. 197/MP/2015 granted the status of deemed licensee to IR which has further been upheld by Hon'ble APTEL. Pl see detailed explanation at Annexure-1.

iR is already connected to ISTS arthree locations (Dadri, Auraiya and Naini) which supplies traction load to GZB-CNB-ALD section. Further approval of ISTS connectivity at Abdullapur and Meerut has been granted in 2018. · · ·

23.14 Noted.

23.15 Indian Railways is a deemed Licensee for transmission and distribution of electricity in connection with working of Railways as per provisions in Railway Act 1989 and IE Act 2003. Hence, Railways is not liable to give access to other entity. Pi refer to explanation at para 4 in Annexure-1.

23.16 Pl refer detailed explanation as per Annexure-1.

23.17 IR is seeking ISTS connectivity as a deemed licensee and not as bulk consumer. IR is already connected to ISTS in UP as detailed in para 23.13 above.

23.18 Indian Railways is a deemed Licensee for transmission and distribution of electricity in connection with working of Railways as per provisions in Railway Act 1989 and IE Act 2003. The transmission line is for dedicated use of IR and IR is not liable to give access to other entity. Hence, question of determination of transmission charges for its usage does not arise. Railway is seeking connectivity with ISTS, so BSPTCL doesn't come into picture. Please also see detailed explanation at Annexure-1 regarding unique status of Railways.

23.19 As mentioned above, it is a dedicated line for Railways. Thus, implication on other entities does not arise. Further, comments in para 23.11 may also be seen.

23.20 Connectivity agreement shall be signed with CTU for the L TA quantum. POSOCO has rightly stated that Railway load is essential in nature and they may do the planning accordingly. Power, in any case, would be required. Further, connectivity with CTU shall- be more reliable than STU connectivity. In addition, comments as mentioned at para 23.11 may also be referred.

23.21 This is repetition and is in contradiction to its assertion earlier that its network is underutilised.

�-

23.22 Indian Railways is a deemed Licensee for transmission and distribution of electricity in connection with working of Railways as per provisions in Railway Act 1989 and IE Act 2003. The transmission line is for dedicated use of IR and IR is not liable to give access to other entity. Pl refer detailed explanation as given in Annexure-1.

23.23 Noted.

23.24 Pl see comments at para 23.22.

23.25 As explained above, it is requested to grant ISTS connectivity at Pasauli. If required, an exclusive meeting in this regard may be called with all concerned.

Status of Indian Railways as Deemed Licensee as per provisions of Railway Act and IE Act and orders of Hon'ble Supreme Court, APTEL and CERC

Indian Railways is a deemed Licensee for transmission and distribution of electricity in connection with working of Railways. Following provisions in Railway Act 1989 and IE Act 2003 and orders by Hon'ble Supreme Court, APTEL, CERC and clarification issued by Ministry of Power grant the status of deemed licensee to Indian Railways.

1. Provisions of the Railways Act, 1989 empowering the Indian Railways toundertake distribution of electricity for the purpose of RailwayAdministration;Indian Railways has the authority to distribute and supply electricity under the

Railways Act, 1989. The relevant provisions of the Railways Act, 1989As per Section 2(31) of Railway Act "railway" means a railway, or any portion ofa railway, for the public carriage of passengers or goods, and inC/udes

c. all electric traction equipments, power supply and distributioninstallations used for the purposes of, or in connection with, a railway;

Section 11 of Railway Act 1989 stipulates Power of Railway Administration toexecute all necessary works- Notwithstanding anything contained in any otherlaw for the time being in force, but subject to the provisions of this Act and theprovisions of any law for the acquisition of land for a public purpose or forcompanies, and subject also, in the case of a non-Government railway, to theprovisions of any contract between the non-Government railway and theCentral Government, a railway administration may, for the purposes ofconstructing or maintaining a railway-

(g) erect, operate, maintain or repair any electric traction equipment,power supply and distribution installatioi1 in connection with the working ofthe railway;

2. Third proviso of Section 14 of the Electricity Act, 2003 recognizing the IndianRailways which is part of the Government of India to be a deemed licensee forundertaking distribution of electricity states as below.

"Provided also that in case an Appropriate Government transmits electricity or distributes electricity or undertakes trading in electricity, whether before or after the commencement of this Act, such Government shall be deemed to be a licensee under this Act, but shall not be required to obtain a licence under this Act:"

3. Section 173 of the Electricity Act, 2003 which provides for supervening applicationof the provisions of the Railways Act, 1989 viz-a-viz the Electricity Act, 2003.

4. The decision of the Central Electricity Regulatory Commission in the judgment andOrder dated 05.11.2015 passed in Petit.ion No. 197/MP/2015 granting the statusof deemed licensee to l R. In its Order, CERC states that

"It is clear that in so far as Indian Railways are concerned, they will be governed by the provisions of the Railways Act for constructing transmission lines and distribution installations for the purpose of supply of power to the railways without having to take any license from the appropriate Commission for transmission or distribution of electricity. In other words, the Indian Railways can be treated as authorized entity under the Railways Act for carrying out transmission and distribution activities for ensuring supply of power in connection with working of the railways. That being the case, the requirements of MSETCL for declaration regarding the area of operation, other terms and conditions of license and Standard of Performance as required in case of a distribution licensee under the Electricity Act will not be applicable in case of Railways ..... "

5. Hon'ble APTEL in IA No. 445 of 2015 filed in Appeal No. 276 of 2015 dated16.12.2015 has upheld the status of Indian Railways as a deemed licensee.

6. The decision of the Hon'ble Supreme Court in General Manager, NorthernRailways v Chairman, Uttar Pradesh State Electricity Board and Others (2012).The said order of Supreme Court recognizes that the Railways is governed byRailways Act, 1989. It held that IR is an authorized entity under the Railways Actto undertake transmission and distribution activities in connection with the workingof the Railways.

7. Letter dated 06.05.2014 issued by Ministry of Power recognizes the status of IRas deemed licensee as per third proviso to Section 14 of IE Act 2003.

8. Regarding connectivity to ISTS/state network, CERC held as under:

"51. The Indian Railways can be connected with ISTS c;iirectly or through statenetwork. The Commission is inclined to consider option "c" as provided in CEAReport with slight modification. The drawl points from ISTS located within a Stateshall be treated as a single entity for the purpqse of scheduling. Thisarrangement according to CEA and POSOCO may lead to fragmented controlarea. Therefore, the group of TSSs situated in a State and connected directlywith ISTS shall be treated as one "fragmented control area' and the responsibilityfor the purpose of scheduling, metering, balancing, applicability of ISTS chargesand losses etc, shall vest in the concerned RLDC. In so far as the TSSs of IndianRailways connected to State network are concerned, the responsibility for thesefunctions shall vest in the concerned SLDC."

9. CERC Order states as below:

''In view of the above discussion, the prayers of the petitioner are decided as under:

(a) In the light of the judgment of the Supreme Court in UOI Vs UPSEB supra, it isheld that the petitioner is an authorized entity under the Railways Act toundertake transmission and distribution activities in connection with the workingof the railways, independent of its status under the Electricity Act. Therefore, theinformation sought by MSETCL vide its letter dated 6.7.2015 are not relevant forgrant of connectivity and concurrence to the petitioner for scheduling of powerfrom RGPPL and GUVNL through the /STS and State networks by availing longterm access or medium term open access in terms of Connectivity Regulations.

(b) The petitioner is a deemed licensee under third proviso to Section 14 of theElectricity Act and no separate declaration to that effect is required from theAppropriate Commission. The petitioner as a deemed licensee shall be boundby the terms and conditions of licence specified or to be specified by theAppropriate Commission under proviso to Section 16 of the Electricity Act.

(c) The drawl points from ISTS located within a State shall be treated as a singleentity for the purpose of scheduling. The group of TSSs situated in a State andconnected directly with ISTS may be treated as one "fragmented control area

l!

and the responsibility for scheduling, metering, balancing, applicability of ISTScharges and losses etc, shall vest in the concerned RLDC. For the TSSssituated in a State and connected to State network, these functions shall vest inthe concerned SLOG.

(d) All concerned RLDCs, State Transmission Utilities and SLDCs are directed tofacilitate long term access and medium term access in terms of ConnectivityRegulations from the generating stations or other sources to the facilities andnetwork of Indian Railways."
