implementation. Therefore, in order to evacuate and transfer power from above ultra
mega solar power park (700 MW), a 400kV D/c interconnection between Solar
Power Park and Banaskantha(PG) substation is proposed.
Study Results with above proposed transmission system is enclosed at Exhibits-6-
8. From the studies, it is observed that under n-1 contingency, loading on 400kV
14
Banaskanta – Sankhari D/c is critical. However with bypassing of LILO for Vadavi
(Ranchodpura) - Zerda (Kansari) line (at 400/220kV Sankhari (GETCO) substation),
loading is in order. However, the issue is proposed to be deliberated in the Standing
committee meeting of WR constituents.
In view of the above, following interstate transmission system for connectivity & LTA
is proposed :
Transmission System for Connectivity:
Banaskantha (Radhanesda) PS – Banaskantha (PG) PS 400 kV D/c along with 2
nos. 400 kV line bays at Banaskantha (PG) PS (to be implemented by POWERGRID).
2 nos. 400 kV line bays at Banaskantha (Radhanesda) PS for Banaskantha
(Radhanesda) PS – Banaskantha (PG) PS 400 kV D/c line (to be constructed by
GPCL)
The connectivity of Banaskantha (Radhanesda) PS with the grid shall be established
after the commissioning of above system and Bhuj PS – Banaskantha PS –
Chittorgarh PS 765 kV D/c corridor including Banaskantha PS – Sankhari (GETCO)
& Chittorgarh PS – Chittorgarh (RVPN) 400 kV interconnections being implemented
by POWERGRID under Green Energy Corridor-ISTS scheme and expected to be
commissioned by July’18.
Transmission System for LTA:
Regarding power transfer within WR, it may be mentioned that existing and planned
transmission infrastructure shall be sufficient to enable dispersal of power within WR.
10. Long Term Access application of M/s Essel Saurya Urja Company of
Rajasthan Ltd.
M/s Essel Saurya Urja Company of Rajasthan Ltd. located at Phalodi & Pokharan in
Rajasthan has been granted LTA in Standing Committee meeting of NR for 750 MW
out of which 400 MW is to be consumed within NR and 350 MW is to be transferred
from NR to WR.
Regarding power transfer from NR to WR, it may be mentioned that existing and
planned transmission infrastructure shall be sufficient to enable power transfer from
the generation project to WR and power shall flow by displacement to WR.
Accordingly, it is proposed to grant LTA for transfer of 350 MW from NR to WR .
11. Connectivity Application of Adani Green Energy Ltd. (AGEL) : 300 MW
The subject application was discussed in the 22nd LTA & Connectivity meeting of WR
constituents held on 30-11-2015 wherein connectivity of M/s AGEL to Sami (Adani) /
15
Banaskantha(PG) was proposed. M/s AGEL informed that Sami substation is around
15km from the project site whereas Banaskantha substation is more than 90km from
the project. Accordingly, it would be preferable to connect to Sami (Adani) substation
which is further connected to Dehgam S/s. M/s AGEL was requested to confirm
about availability of land for development of 220kV level at Sami Switching Station.
Subsequently, AGEL vide its letter ref: AGEL/PG/02022016 dated 02.02.2016 has
informed that land is available at the Sami Switching Station for termination of 220kV
line and installation of one no. 400/220kV ICT.
As per extant planning criteria, The ‘N-1’ criteria may not be applied to the immediate
connectivity of wind/solar farms with the ISTS/Intra-STS grid. Hence, following
system is proposed for connectivity of the Solar power project with ISTS:
AGEL - Sami (Adani) 220 kV D/c line
1x500 MVA, 400/220 kV ICT at Sami (Adani) substation
In view of the short time line, it is proposed that AGEL shall construct the above
transmission system.
Members may discuss.
12. Request for enhancement in quantum of Connectivity granted to Surguja
Power Private Limited (SPPL) for 4x150 MW power plant from 490MW to
550MW
M/s Surguja Power Private Limited vide our letter no. C/CTU-
Plg/ConlW/2015/01/Surjuga dated 07-05-2015 has been granted connectivity for 490
MW through following transmission system to be implemented by generation
developer :
SPPL Switchyard - Dharamjaygarh 400kV D/c line
1x125 MVAR 420 kV bus reactor at SPPL switchyard
Subsequently, SPPL vide letter letter no. SPPUPG/161220 15/002 dated 16.12.2015
has requested for enhancement in quantum of connectivity from 490 MW granted
vide intimation letter dated 07.05.15 to 550 MW. Since the connectivity line has
adequate capacity to cater to the proposed connectivity quantum (550MW), it is
proposed to enhance the connectivity quantum from 490 MW to 550 MW with the
above mentioned system to be implemented by generation developer.
13. Revision in the LTA quantum of Chhattisgarh State Power Trading Company
Ltd. (CSPTrdCL).
16
The matter was discussed in the 21st and 22nd LTA meetings held on 17-07-2015
and 30-11-2015 wherein CTU stated that if CSPTrdCL reduces the quantum of
power availed from various generation projects, relinquishment charges in line with
CERC regulations will apply and the same shall be incident on CSPTrdCL. In this
regard, CSPTrdCL vide email dated 28-11-2015 has intimated that they have
decided to file a petition in CERC. However, it is understood that CSPTrdCL is yet to
file the petition in the CERC.
CSPTrdCL may update in this regard.
14. Closure of LTA Application of Heavy Water Board for 17 MW drawal from
440MW Kakrapar Atomic Power station (KAPS) in Gujarat
LTA was granted to Heavy Water Board (HWB) vide our letter dated 19-12-2012 for
transfer 17 MW from Kakrapar Atomic Power station in Gujarat to Heavy Water
Board’s load at Thal in Maharashtra. However, HWB is yet to sign the Long term
Access Agreement with POWERGRID and is also not attending Joint Coordination
Committee meetings of WR. In view of the above, it is proposed to close the subject
LTA application.
15. Closure of Connectivity and LTA Application of Pipavav Energy Pvt. Ltd.
Connectivity as well as LTA for 1200MW was granted to M/s Pipavav Energy Pvt.
Ltd. (PEPL) vide intimations dated 14th September, 2010. Connectivity was granted
with Pipavav TPS – Pirana 400kV D/c (triple) line. LTA was granted for 1200MW with
following target beneficiaries: WR: 550MW, NR: 290MW and ER: 360MW. However,
the PEPL is yet to sign requisite commercial agreements. PEPL is also not attending
the JCC meetings and no progress has been reported till date. Hence, it is proposed
to close the Connectivity and LTA applications of M/s Pipavav Energy Private Ltd.
