Jade Consult, in association with POWERGRID Corporation of India Ltd., is engaged in the development of high-capacity transmission infrastructure designed to strengthen the Integrated Nepal Power System (INPS). The transmission lines associated with this project traverse challenging terrain, spanning altitudes from 185.69 m to 2962.86 m, and are engineered to facilitate the evacuation of approximately 7.54 GW of electricity. This includes power generated from major hydropower projects such as Sunkoshi-2 (1110 MW), Khimti Shivalaya Storage HPP (1853 MW), Sunkoshi-3 (536 MW), and Dudhkoshi-2 Jaleshwor (240 MW).
The initial scope was expanded to cover Lamahi – Chhinchu 400 kV TL Project, a route spanning altitude range from 249.07 m to 1111.93 m and is aimed at enhancing the capacity of Nepal’s national grid. The new 400 kV line will provide essential infrastructure to evacuate power from upcoming generation projects, supporting the reliable transmission of electricity and strengthening the overall Integrated Nepal Power System (INPS).
