Existing Power Exchange Arrangement
• Nepal and India has been exchanging power for many years. Power is being exchanged and traded mainly through 8 points along the Indo-Nepal border.
• Present level of exchange: 50 MW, trading: 180 MW.
• Power exchanges mainly through 33kV and 132kV links.
• To facilitate power exchange, two committees exist: Power Exchange Committee constituted in 1992 and Joint Commission on Water Resources (2000).
