INTERCONNECTION OF INDIA WITH NEPAL

India - Nepal : Present Interconnection

Power Scenario in NepalInstalled Capacity : 607MW (Hydro – 91%)Demand : 600 MW

Over 16 links at 132/33/11 kVAbout 50 MW of power being exchangedNet export to Nepal (about 10% of demand of Nepal met from India)

Supply of 70MU/annum from Tanakpur (India) to Nepal

India – Nepal : Future• A 400 kV inter-connection (initially op. at 220kV level)

between Muzaffarpur(India) and Dhalkebar(Nepal) planned

• The scheme is to be developed by a private developer (IL&FS) in participation with POWERGRID

• For its implementation, two separate JV companies, one for Indian portion (ILFS, PTC, POWERGRID) and other for Nepalese portion (ILFS, PTC, NEA) are proposed

• Two separate DPRs for Indian and Nepalese portion have been prepared by POWERGRID and submitted to IL&FS in Feb-09 & March-09 respectively

• Formation of Joint Venture is under progress
