• About 45000 MW of power to be evacuated from NER throughchicken neck area in north of West Bengal

• A very narrow patch of land (22 km. Width X 18 km length) near

Siliguri having borders of Nepal on one side & Bangladesh on the

other side and is largely habited.

• All transmission lines, railway lines, gas pipe-lines,

telecommunication lines etc. have to pass through the chicken neck

area.

Development of

Tr. System Through Chicken Neck

About 8 nos. of HVDC / EHVAC corridors (each of 6000MW

capacity) may be required with a total width of about 1.5-2 Kms.

The first such +800 kV HVDC corridor from NER to NR has been

commissioned

For this, 3 more corridors of 6000MW each (Total : 24,000 MW) is

nearing completion in the chicken neck area.

Development of

Tr. System Through Chicken Neck

• World’s Largest multi-terminal

800kV HVDC Project (1750 km)

• 3000 MW HVDC terminals at

Biswanath Chariyali & Alipurduar

and 6000 MW at Agra

• Passing through 3 Regions, 4

Planning – Basinwise development

Design : In some cases (Chenab Basin) Generation / Pooling Station Switchyard

Capacity may be equivalent to the ultimate power handling capacity

Implementation (NR)

Tough Terrrain (Hilly, Forest) / Snow Bound terrain / glacier / avalanche prone area(Lahaul / Spiti valley) (height upto 4000mtr)

Time Frame : Working Season 5-6 months in a year due to high snow

Environmental clearances, Transportation (‘Kuccha’ roads, many bridges withmaximum capacity of 9 tonnes.)

High cost of transmission system due to

High Capacity, long distance (to load centre) Transmission line through difficult corridor

Phased development of the generation projects

Low PLF of hydro projects

Recovery of Tariff

Matching generation with Transmission difficult - Uncertainty in implementation of
