Minimum Trans. System required with 1st unit of Pallatana
 Trans. System Under NETC (JV of OTPC, PG & NER
States)
– Pallatana - Silchar 400kV D/c line
 Trans. System (Under POWERGRID)
– Pallatana - Silchar 400kV D/c line
– 2x200 MVA, 400/132kV new S/s at Silchar
– Silchar - Badarpur(PG) 132kV D/c line
– Silchar - Srikona (Assam) 132kV D/c line
– Silchar - Hailakandi(Assam) 132kV D/c line with
LILO of Panchgram-Dullabhchera 132kV S/c line of
AEGCL to connected it with Silchar-Hailakandi
132kV D/c line so as to form Silchar - Panchgram
and Pallatana - Silchar 132kV lines (as agreed in
NERPC)
8
Trans. System likely to be commissioned with 2nd unit of
Pallatana (scheduled in March-2012)
 Trans. System Under NETC (JV of OTPC, PG & NER States)
– Silchar - Bongaigaon 400kV D/c line
 Trans. System (Under POWERGRID)
–
–
Pallatana - Surajmaninagar 400kV D/c line (to be operated at 132kV)
Surajmaninagar – P. K. Bari 400kV D/c to be charged at 132kV
 Trans. System (Under OTPC)
–
2x100 MVA, 400/132kV ICT at Pallatana
 Trans. System (Under Tripura Scope)
–
2x50MVA, 132/33kV substation at Surajmaninagar (upgradable to
400kV)
 Trans. System (Under Meghalaya Scope)
–
2x315MVA, 400/220kV substation at Byrnihat alongwith LILO of one
ckt. of Silchar – Bongaigaon 400kV D/c line
Note : In absence of Byrnihat S/s, upto 500 MW can be evacuated
through Silchar (2x200 MVA) and Pallatana (2x100 MVA) ICTs
9
Major Concerns
 Construction of new S/s at Surajmaninagar (Tripura)
–
–
–
Pallatana – Surajmaninagar 132kV D/c being constructed by
POWERGRID to provide alternate path for evacuation as well
as anticipated to be used for start-up power
New 2x50 MVA, 132/33kV S/s at Surajmaninagar required for
termination of Pallatana – Surajmaninagar 132kV D/c
Awarded by Tripura, needs to be expedited.
 Construction of new 400kV S/s at Byrnihat (Meghalaya)
–
–
–
–
2x315 MVA, 400/220kV S/s at Byrnihat to established by LILO
of one circuit of Silchar – Bongaigaon 400kV D/c line
Critical for smooth operation of 408 kms long Silchar –
Bongaigaon 400kV section
MeSEB signed agreement with POWERGRID for construction
of Byrnihat S/s as consultancy works
Scheduled to be completed in 30-36 months provided all
formalities like release of payment, hand over of land etc. are
completed at the earliest, which are still awaited
10
Major Concerns
 Construction of new 400kV S/s at Azara (Assam)
–
–
–
2x315 MVA, 400/220kV S/s at Azara to established by LILO of
Silchar - Bongaigaon 400kV D/c line
Critical for smooth operation of 408 kms long Silchar –
Bongaigaon 400kV section
Activities for construction yet to be started by Assam
 Strengthening beyond Bongaigaon
–
–
–
–
NER may have surplus during off-peak period (even though
entire power from Pallatana & Bongaigaon have been
allocated to NER states
Strengthening beyond Bongaigaon needs to be implemented
promptly for reliable transfer of power
POWERGRID is implementing re-conductoring of SiliguriPurnea 400kV D/c line, expected to be completed by March,
2012
Bongaigaon – Siliguri & Purnea – Biharsharif 400kV D/c lines
are being implemented under private sector and have been
awarded to M/s Sterlite. Implementation of the same needs to
11
be expedited
