Kathmandu – The Chilime-Trishuli 220 kV transmission line, spanning 28 kilometers from Rasuwa’s Chilime Hub Substation to Nuwakot’s Trishuli 3B Hub Substation, is now operational. Energized on Wednesday evening, the line can transmit up to 1200 MW of power from local hydropower projects into Nepal’s national grid.
The project, costing around NPR 3.62 billion, is funded by the Government of Nepal, Nepal Electricity Authority (NEA), and supported by the German Development Bank (KfW) and European Investment Bank. The line initially connects power from the Rasuwagadhi (111 MW), Sanjen (42.5 MW), and Lower Sanjen (14.8 MW) projects to the grid.
Due to challenging Himalayan terrain, over 20 kilometers of access roads were constructed, with materials airlifted for the installation of 76 towers. The transmission line includes double-circuit and multi-circuit sections to support future hydropower projects, including the 216 MW Upper Trishuli-1.
About: Chilime–Trishuli
The Chilime–Trishuli 220 kV transmission line is a major energy project in Nepal, spanning 28 kilometers from Rasuwa to Nuwakot. Designed to transmit up to 1200 MW, it integrates power from hydropower plants in the Trishuli River region into Nepal’s national grid. Funded by the Nepal government, NEA, and international banks, this line strengthens Nepal’s energy capacity and reduces dependence on imports. Despite challenging mountainous terrain, the project’s completion marks a milestone in supporting Nepal’s energy infrastructure and future hydropower growth.
