East-North Interconnection Project
400kV Double Circuit transmission lines (900 CKm)
Home / Projects / East-North Interconnection Project

ENICL, the first-of-its-kind Mega Independent Power Transmission Project to be awarded in India, was set up with an aim to evacuate power from the North-East and Eastern states to the Northern Region of India. It has been identified as one of the highest priority lines by the Power System Operation Corporation Limited (POSOCO) as it provides critical connectivity for the transfer of power from the generating plants in the North Eastern region. Also, this project will address the critical issue of the power shortfall during non-monsoon months, thereby bringing significant relief to the people of Assam.

Transmission lines have traversed through difficult terrains in Bihar, West Bengal and Assam; surmounted challenges such as floods and earthquakes, and crossed large rivers such as the Ganges, Teesta and Kosi, and ‘Right of Way’ hurdles.

The project involves the establishment of two 400 kV Double Circuit transmission lines (with a total line length of 450 Km) that passes through the Indian states of Assam, West Bengal, and Bihar. The company would operate and maintain these for a minimum tenure of 25 years.
