Phukot – Betan – Dododhara 400 kV Transmission Line

  • ONGOING
  • Construction Supervision

NEC is carrying out the design check and construction supervision of Phukot – Betan – Dododhara 400 kV Transmission Line (Karnali Corridor Transmission Line Project) od RPGCL.

Rastriya Prasaran Grid Company is constructing from Phukot (Kalikot) - Betan (Surkhet) - Dododhara (Kailali) 400 kV transmission line and associated substations. This line is intended to tap 4,000 MW hydropower generated from Karnali Basin to National Grid. This transmission system comprises of 96 kilometers 400 kV double circuit transmission line and three associated substations.

The project lies in Karnali Province and affected Districts are Kalikot, Accham, Dailekh, Surkhet and Kailali. The topography of the project area is mostly hilly terrain and few plain terrains in Kailali District. The line crosses maximum altitude of 2,100

m. There is one major river crossing at Karnali River with span of aroun d 1,300 m.

For this project, 400 kV normal towers are to be constructed. 400 kV Special tower shall be required for long span (Karnali River) crossing maintaining minimum water level of 415m water level (MSL) and other required clearance.

The Construction of the Karnali Corridor Transmission Line is integral to enhancing Nepal's energy infrastructure, contributing to a more sustainable, reliable, and environmentally - friendly power supply. By facilitating efficient transmission from renewable energy sources, this Project plays a pivotal role in addressing climate change, reducing poverty, and fostering long - term economic growth. The expanded transmission infrastructure will enhance grid efficiency, stabilize line voltage, reduce technical losses and significantly bolster the reliability and resilience of the nation’s electricity supply. Additionally, it will support the reduction of power imports in the Integrated Nepal Power System and position of the Country to increase power exports. The Project encompasses the development of three 400 /132 kV substations at Phukot, Betan and Dododhara.

NEC is the Consultant for the design review and construction supervision works of the Transmission Line Project. The contract is awarded in two parts: first one for the design review works and second part for the construction suppression works.
