Page 2 of 18

Details of the applications are given below:

1.0 Connectivity & LTA to GHAVP Nuclear power plant (2X700MW) of M/s NPCIL in Haryana

The connectivity & LTA application from NPCIL was discussed during the 7th Meeting

of Northern Region Constituents regarding Connectivity/Long Term applications.

According to the application, the connectivity as well as Long Term Access for 1400

MW is from upcoming Nuclear power generator (2X700MW) of M/s NPCIL for

Gorakhpur Haryana Anu Vidyut Pariyojna (GHAVP) located at Fatehabad, Haryana.

As per the application, the Connectivity was sought w.e.f. Sep.’2020 with target

Beneficiaries as Northern region.

Following Transmission System for Connectivity & LTA was proposed during the 7th

meeting of Connectivity & LTA applications in NR:

Proposal: GHAVP Nuclear plant (2X700MW) of M/s NPCIL is in proximity of Fatehbad 400/220

kV substation of POWERGRID. Hence, connectivity can be granted at Fatehbad.

Presently, Fatehbad 400/220 kV S/s is connected with LILO of one circuit of Moga-Hissar

400 kV D/c line. LILO of Moga-Bhiwadi 400 kV D/c line at Hissar is under implementation

and therefore another 400 kV D/c line would be available between Moga & Hissar.

System studies have been carried out for 2020 time frame with the proposal as given

below:

Sl. No. Case Exhibit No.

1 Without considering NPCIL Generation I

2 With NPCIL generation II

3 With Outage of NPCIL-Hissar 400 kV S/c III

4 With Outage of Khedar-Kirori 400 kV S/c Line IV

5 With Outage of both circuits of Khedar-Kirori 400 kV D/c line V

From the studies it has been seen that all line loadings are well within limits under normal

as well as contingency situations.

Therefore, following transmission system was proposed for connectivity as well as for

evacuation of power from NPCIL generation:

Proposal for Connectivity:

� Fatehbad - NPCIL generation 400 kV D/c line

Proposal for Long Term Access:

� LILO of second circuit of Moga-Hisar 400 kV D/c line at Fatehbad

� LILO of both circuits of Moga-Hisar 400 kV D/c line at NPCIL generation switchyard

Hence, Connectivity & Long Term Access was proposed to be granted with the above

mentioned Transmission system.


Page 3 of 18

The Connectivity and LTA studies for the subject scheme came up for discussion in

the 36th SCM of Northern region Transmission Planning held on 13/07/2015. HVPNL

indicated that NPCIL had acquired land for 4*700 MW, whereas LTA & Connectivity

application was made for 2*700 MW. Thus the proposed scheme may need

changes considering the final capacity of 4*700 MW. Subsequently, CEA advised

that NPCIL and HVPNL to discuss and resolve the matter and confirm the capacity

for which the evacuation scheme is to be planned by CEA/CTU.

Accordingly, as indicated by NPCIL letter dated 12/01/2016, a meeting was

organised at HVPNL on 07/01/2016 to discuss the power evacuation and Start up

power (220 kV). HVPNL suggested that scheme should be planned for ultimate

capacity of 4*700MW. However, NPCIL desired considering the present financial

sanction for 2*700 MW, for which Connectivity and LTA applications have been

made, it prefers to retain the same applications, rather than making new applications

(4*700MW) for which no financial sanction is available.

Therefore, it has been proposed by NPCIL that power evacuation scheme for

GHAVP may be considered based on the earlier application (2*700MW). Therefore,

the LTA & Connectivity may be granted with above said Transmission system.

In addition to above mentioned system 125 MVAR bus reactor may be provided at

generation switchyard and switchgear equipment may be designed with 50 kA fault

level.

Members may deliberate.

2.0 Connectivity & Long Term Access to M/s Noida Power Company Ltd. for drawl

of 500 MW as a bulk consumer in Greater Noida area, Uttar Pradesh.

The issue of grant of Connectivity and LTA to Noida Power Company Ltd. (NPCL)

was discussed in various Standing Committee/LTA & connectivity meetings,

however, the same could not be resolved. During 34th SCM held on 08/08/14, it was

suggested that NPCL may approach CERC. Accordingly they had approached

CERC and CERC vide their order dated 16/09/2015 has directed to process the

applications. The detailed agenda for Connectivity & LTA to M/s NPCL was

circulated among all Northern region Constituents and following was proposed:

1) To grant LTA for drawl of 500MW power at G. Noida 765/400kV S/s of UPPTCL

through UPPTCL intra state system w.e.f. 1/10/2017 to 30/9/2042.

2) The already granted connectivity at 400/220 kV G. Noida (new) proposed under

ISTS, is proposed to be cancelled as M/s NPCL would be connected to UPPTCL

substations as mentioned in NoC and UP has stated that their system is capable to

supply 500 MW to NPCL. Further, the grant of Connectivity may be taken up by

UPPTCL.

3) The scheme NRSS XXXIII consisting of establishment of 2x500 MVA, 400/220kV

GIS substation at Greater Noida (New) along with Ballabhgarh – Greater Noida


Page 4 of 18

(New) 400 kV D/c line as agreed in the 31st Standing Committee Meeting on

02/01/2013 may be dropped.

The detailed agenda for the same is attached at Annexure-I for reference.

Members may discuss

3.0 Long Term Access for 264 MW to M/s Jaiprakash Power Ventures Ltd. for

Karcham Wangtoo Hydro Electric Plant in Himachal Pradesh.

LTA was earlier granted for 704 MW for Karcham Wangtoo generation project with

target regions as NR (440 MW), WR (176 MW) and SR (88 MW).

However, JPVL vide its letter dated 31.03.2014 and note submitted on 01.04.2015

has requested POWERGRID to reinstate the earlier granted LTA to Northern Region

beneficiaries for 704 MW instead of NR, WR and SR.

The matter was discussed during the 7th NR LTA/Connectivity meeting, CEA

suggested Jaiprakash Power Ventures Ltd. to apply with a new LTA application as

the change in LTA Quantum is more than 100 MW.

Subsequently, a fresh LTA application has been received from Jaiprakash Power

Ventures Ltd. in Aug’2015 for transfer of 264 MW of power from Karcham Wangtoo

generating plant to Northern region beneficiaries. As per the application, the LTA is

sought from Aug’2015 for 25 years.

For the revised grant of power transfer to NR, no augmentation / system

strengthening was identified as it was granted through the existing system only,

therefore, the above said LTA may be granted subject to the fulfillment of regulatory

provisions.

It has been seen that power transfer from Karcham Wangtoo plant to Northern

region beneficiaries shall enable availability of more power in Northern region.

Members may discuss

4.0 Connectivity & Long Term Access to M/s Lucknow Solar Power Development

Corporation Ltd. for 270 MW from Jalaun Solar Park in Uttar Pradesh.

8.0 Connectivity to M/s Aditya Birla Nuvo Ltd. for 150 MW for Solar generating

plant in Rajasthan.

Connectivity application has been received in September’2015 from M/s Aditya Birla

Nuvo Ltd. for 150 MW quantum of power from Solar generating plant Project located

in Sikar, Rajasthan. As per the application, Connectivity has been sought from

Oct’2016.

As per the application, the nearest ISTS point is Sikar (POWERGRID) 400/220 kV

substation which is about 30 km from the generating plant. However, due to non-

availability of space for 220 kV bays at Sikar 400/200 kV (PG) substation, the same

cannot be given. The other option for providing connectivity is through LILO of one

circuit of Sikar (PG)-Sikar (RVPNL) 220 kV D/c at the Solar generating station.

RVPNL may provide their consent for the same.

Taking into consideration very early commissioning schedule of the solar plant ie.

Oct’2016 (as per the application) the construction of dedicated line may be taken up

by the applicant itself.

Subsequently, it is to mention that mere connectivity does not full fills the condition of

adequacy of transmission system for transfer of power to target beneficiaries and the

grant of connectivity shall not entitle to interchange any power with the grid unless it

obtains Long-Term Access, Medium Term Open Access or Short Term Open

Access.

Transmission beyond immediate evacuation system is to be evolved once the

applicant applies for the LTA. Hence, applicant may apply for Long Term Access.


9.0 Connectivity to M/s Indian Oil Corporation Limited for 100 MW as bulk

Consumer for their Mathura refinery.

Connectivity application dated 15/06/2015 received from Indian Oil Corporation

Limited as a bulk consumer for 100 MW quantum of Mathura refinery, Uttar Pradesh

was discussed during the 7th Meeting of Northern Region Constituents regarding

Connectivity/Long Term applications.

Connectivity to the applicant was agreed with the following Transmission system:

� 220 kV D/c line from Mathura Refinery to Prithala 400/220 kV S/s

However, following issues have been observed while processing the Connectivity

application:

1) Connectivity is being sought as a bulk consumer, however, IOCL plans to

connect the generator as it is mentioned in the application that captive power

plant is proposed to be kept floating with the grid in import mode for meeting bulk

power requirement and emergency backup situation.


Page 11 of 18

2) If the applicant is already connected to the grid then in order to avoid the loop

flows, the existing connectivity may have to be opened.

3) Applicant to indicate by what time the load expansion is expected and

connectivity line should be matched with that time frame.

4) As the applicant is applying as a bulk consumer, therefore, it may not be allowed

to inject into the grid.

It was agreed during the above mentioned meeting that Connectivity may be granted

to M/s IOCL and they may take up the issue with CERC for construction of the line.

However, to discuss the various issues regarding implementation of connectivity line,

based on the request of M/s IOCL, a meeting was held between CTU and M/s IOCL

on 27/08/2015 in M/s IOCL has expressed its desire to connect to STU network for

which STU consent is required. No further communication has been received from

IOCL in this regard.

In view of this, the grant of connectivity to M/s IOCL for 100 MW as a Bulk Consumer

shall be granted based on the feedback from IOCL. IOCL may please update the

same.

In addition to above mentioned system 125 MVAR bus reactor may be provided at

generation switchyard and switchgear equipment may be designed with 50 kA fault

level.

As per the application, Connectivity was sought w.e.f. Dec. 2017 for drawl of startup

power and commissioning requirement.

It was mentioned in the earlier meeting that mere connectivity does not full fill the

condition of adequacy of transmission system for transfer of power to target

beneficiaries and the grant of connectivity shall not entitle to interchange any power

with the grid unless it obtains Long-Term Access, Medium Term Open Access or

Short Term Open Access. Transmission beyond immediate evacuation system is to

be evolved once the applicant applies for the LTA. Hence, NTPC was asked to apply

for LTA.

NTPC assured that they would submit the LTA application within 1 month, however,

the same has not received till yet.

Substation(20.30km), 132/33kV Dehra(HPSEB) substation(22.81km) & 400/220kV

Hamirpur (POWER GRID) substation (40km). As the generation step up voltage as

informed by the applicant is 132kV and there is no ISTS substation in the vicinity, the

connectivity need to be provided at STU substation.

As the representative from HPPTCL or HPSEBL was not present in the meeting,

therefore, a separate meeting for discussing the issues regarding grant of

Connectivity to Dhaulasidh HEP was held on 24/08/2015 among members from

CEA, POWERGRID, HPSEB, HPPTCL & SJVNL. In the meeting, following options

were discussed for providing Connectivity to Dhaulasidh HEP:

1) SJVNL may construct a 132 kV D/c line upto the newly proposed HPSEBL/HPPTCL

132/33 kV Nadaun substation along with the construction of requisite 132 kV bays on

both ends. However, cost of construction of Nadaun substation along with LILO of

both circuits of Dehra- Mattansidh 132 kV D/c line at this substation may be built by

HPSEBL/HPPTCL as an intra-state transmission works.

2) SJVNL may construct the LILO of both circuits of Dehra-Mattansidh 132 kV D/c line

at their generation switchyard.

3) SJVNL may construct a 132 kV D/c line from Dhaulasidh generation switchyard to

Mattansidh 220/132 kV substation of HPSEBL.

A meeting regarding this issue among HPSEBL/HPPTCL & SJVNL was held on

09/09/15 and further, SJVNL vide letter dated 08/10/2015 has informed that

considering techno-economic reasons, the Connectivity of Dhaulasidh generation

plant may be granted through 220 kV D/c line from Dhaulasidh HEP to 400/220 kV

S/s at Hamirpur (PG).

It may be mentioned here that the connectivity line shall have to be constructed by

SJVNL including bays at both ends, in line with CERC regulations.


12.0 Pending Connectivity & Long Term Applications pertaining to Northern region

It is to inform that there are many Long Term Access applications where LTA could

not be granted as the LTA applicants have sought repeated extensions in grant of

Long Term access by requesting to keep their applications ‘in abeyance’. Similarly,

some applications could not be granted LTA as the regional constituents opined and

informed about the lack of progress of generation plant.

It was deliberated in the last LTA/Connectivity meeting that Connectivity to these

projects was agreed by PTCUL and LTA granted by CTU beyond Kashipur. Now as

the system is being developed as deemed ISTS, these generators need to apply

fresh for connectivity to CTU, which would be granted by CTU. Phatabyung HEP &

Alaknanda HEP have signed LTAA, however based on revised connectivity

application, the injection point for LTA would also get changed to deemed ISTS

network and the already signed agreement would also have to be revised. After

grant of connectivity and LTA, PTCUL would require to sign Implementation

Agreement with the generators in line with CERC Regulations.

i. Connectivity to Tapovan Vishnugarh Hydro project (520 MW) of M/s NTPC Ltd.

(THDC) substation

� Pipalkoti-Srinagar 400 kV D/c Quad line

� Srinagar-Kashipur 400 kV D/c (Quad) line

� 8 Nos. 400kV line bays in Pipalkoti substation.

It is proposed that connectivity to Pipalkoti Hydro project (444 MW) of M/s THDC

India Ltd. may be granted to M/s THDC India Ltd. with the above composite system.

However, PTCUL shall sign the implementation agreement with the generator as per

the CERC guidelines.

Note: It may be mentioned that since integrated transmission system has been

evolved for Tapovan Vishnugarh, Akalnanda & Pipalkoti hydro projects, therefore,

the Connectivity & LTA shall be granted for each project based on the

commissioning schedule. The integrated transmission system is to be developed in a

phased manner depending on the commissioning schedule of the generation

projects.


C) Other Projects: It was deliberated in the 7th LTA/Connectivity meeting held on

14/07/2015 that there are certain other projects who had applied connectivity to

PTCUL, however they had not applied for LTA to CTU. In addition some of the

generation developers have neither applied for connectivity nor LTA. PTCUL may

impress upon those generators to apply for connectivity and LTA to CTU.

14.0 Inter – Regional LTA Applications to NR

Based on LTA applications and Central Sector allocations, total power transfer

requirement towards NR comes out to about 26000MW. If certain

uncertain/abandoned/closed applications are not considered, power transfer

requirement reduces to about 23500 MW. In addition to the import requirement of

NR assessed above, additional requirement of about 2500 MW power transfer to NR

is envisaged from following generation projects in WR (& SR):


Page 17 of 18

Sl No.

Generation Projects Region Additional Allocation to NR (MW)

1 KSK Mahanadi Power Company Ltd WR 1000 (Firm)

2 MB Power (MP) Ltd. WR 200 (169MW Firm)

3 MB Power (MP) Ltd. WR 144

4 Suzlon Power Infrastructure Ltd. (3 applications, location of project in SR)

6 Rewa Ultra Mega Solar Ltd. WR 300

7 DB Power Chhattisgarh Ltd. WR 75 (Firm)

8 Maruti Clean Coal & Power Ltd * WR 205 (Firm)

9 TRN Energy Ltd * WR 240 (Firm)

Grand Total 2464 MW

* TRN Energy and Maruti Clean Coal & Power Ltd. had submitted LTA applications against firm PPAs signed with beneficiaries in NR; however same were closed on account of incomplete applications. Above mentioned quantum of WR – NR power transfer desired by TRN and DBPCL

and MCCPL has been considered in studies considering that they have firm PPA as

they may apply afresh. In addition to above applications, LTA application of Barethi

STPS indicates about 871MW power allocation to Northern Region. Hence, the total

power transfer requirement to NR after considering above applications is likely to be

about 26500-27000 MW.

The above mentioned was discussed during the 22nd meeting of WR constituents

regarding Connectivity/Open Access held on 30.11.2015, wherein it was mentioned

that since generation projects in WR (particularly in Chhattisgarh) and in Odisha,

which have strong connectivity with WR (via Chhattisgarh), have materialised in

time, the WR – NR corridor gets stressed. After detailed deliberations, it was decided

during the meeting that the above mentioned applications (from Sl. No. 1 to 7) shall

be granted LTA to NR with the following inter-regional corridor:

New WR – NR Inter Regional Corridor

• Establishment of New 2x1500MVA, 765/400kV Substation at Allahabad

• Vindhyachal Pool – Allahabad (New) 765kV D/c line

• Allahabad (New) – Lukhnow 765kV D/c line

• LILO of Sasaram – Fatehpur 765kV S/c line at Allahabad (New)

• LILO of Meja – Allahabad 400kV D/c line at Allahabad (New)*

*Note: While carrying out the above studies it was observed that Allahabad –

Allahabad 400 kV D/c line becomes critically loaded. Accordingly in this case LILO of

Allahabad – Kanpur 400 kV D/c line at Allahabad (New) has been considered and

with this problem of critical loading of Allahabad – Allahabad (New) gets alleviated.


Page 18 of 18

Considering the above, the studies have been carried out with a total import of about

27000 MW to Northern region. The results of the studies with and without additional

transmission system are enclosed at:

• Base Case (Without Additional Corridor) Exhibit - A

• Outage of Agra – Gwalior 765 kV S/c Exhibit –B

(Without Additional Corridor)

• Base Case with Additional Corridor Exhibit – C

• Outage of Agra - Gwalior 765 kV one circuit Exhibit –D

(With Additional Corridor)

From the study results it may be seen that under the outage of one circuit of Agra –

Gwalior 765 kV line the other circuit gets loaded to about 3100 MW without

additional corridor. Studies with strengthening indicate that there would not be any

problem in transferring the envisaged transfer of power. This shall also facilitate in

catering to some contingencies under N-I-I outage & transfer of economic power

from outside NR, if required. Here it may be mentioned that additional strengthening

would not only transfer the envisaged LTA quantum but would also help in providing

some margins which can be utilized for grant of access to the new applicants.

Further, as per a recent CERC order, LTA to NR granted to M/s Jindal India Thermal

Pvt. Ltd. (JITPL, Odisha) for 834MW needs to be re-allocated to other generation

projects in queue for power transfer to NR. Moreover, M/s Sterlite (Odisha) (200MW

to NR) and Bina Power Supply Co. Ltd. (MP) (132.675MW to NR) have also filed

similar petitions in CERC regarding relinquishment of their LTA quantum towards

NR. Considering this scenario, studies would be carried out and LTA to the

applicants in order of their priority shall be discussed and granted in line with CERC

regulations.
