POWERGRID’s TRANSMISSION SYSTEM FOR
DEVELOPMENT OF NORTH EASTERN REGION (NER)
At present, POWERGRID has a transmission network at
different voltage levels viz. 400kV, 220kV and 132kV level for
distribution of power from various central sector generating
stations to different states in North-Eastern Region as well
as for Export/Import of power with neighbouring states/
region. POWERGRID’s transmission system in NER consists
of about 5,380 ckt. kms. of transmission lines including
919ckt. km. of interregional lines between NER & ER and
14 sub-stations. POWERGRID has already invested over
Rs. 1500 Crore in NER for development of transmission
network. The transmission system contains high capacity
lines viz. 400kV D/c Misa – Balipara – Bongaigaon – Malda
corridor, which is operational since early 2000. However,
on account of pegging of transmission tariff in NER at 35p/
kwh POWERGRID has already incurred a revenue loss of
Rs. 684.95 Crore till 2004-05. As per current calculations,
POWERGRID shall incur a total loss of Rs. 830.06 Crore by
the end of 2006-07.
POWERGRID is also executing few transmission
lines on deposit work basis like 132kV Ziro-Daporijo-
Along transmission system, 220kV Kathalguri-Deomali
transmission system, and 132 kV Balipara-Khupi-Kimi
transmission line which is scheduled to be completed
shortly. In order to ensure reliable supply of power to
the states of the North-Eastern region, POWERGRID is
planning to execute “Missing Link Transmission System in
NER” with a total cost of about 60cr. in near future.
In future, generations projects of about 4000MW capacity
comprising of Kameng(600 MW), Lower Subansiri(2000
MW) and Tipaimukh HEP(1500 MW) are scheduled to
come up by the end of 11th plan / early 12th plan. The
transmission schemes corresponding to the above
generation projects are in advance stages of finalization.
Besides the projects mentioned above, Govt. of India has
launched initiative of 50,000 MW hydro projects which
includes 40,000MW hydro power projects in NER, Sikkim
and Bhutan. Keeping in view the on-going projects in
Sikkim & Bhutan and other future projects in NER, the
total power need to be evacuated from NER, Sikkim and
Bhutan is of the order of 50,000 MW. This power would
be transferred through narrow corridor of Chicken Neck
area, where there is a serious Right of Way problem, for
onward distribution to deficit regions like NR and WR. In
view of the requirement of transfer of huge power through
narrow and difficult terrain, it is important that only high
capacity transmission corridors each of ultimate capacity
5000-6000 MW would need to be constructed.
For evacuation of power from the future hydro projects
of various capacity it is proposed to develop a number
of power pooling stations, where power from the
nearby generating stations would be pooled for further
transmission to different regions over hybrid transmission
system of high capacity HVDC and AC lines. To evacuate
about 50,000 MW power from NER & Sikkim/Bhutan, it is
proposed that about 6-7 nos. of 6000MW +800kV HVDC
bipole and 4-5 nos. of high capacity AC lines would be
required.
In view of the requirement of evacuation of bulk quantity
of future power from hydro projects in NER, Sikkim and
Bhutan, it is important to firm up the commissioning of
substantial capacity of generation projects at a time so as to
utilize the transmission corridors in an optimum manner. It
is therefore, required to go ahead with Integrated Resource
Planning so that the cost of energy transferred from NER
to other regions over the high capacity transmission
corridors can be optimized.
