Physical construction work of 216 MW Upper Trishuli Hydropower Project has started in Rasuwa. The construction of the project has started as soon as the work of the ventilation tunnel used to go to the underground powerhouse has started.

According to the project, the first blast took place on Tuesday for rock construction work for the construction of a total of 246 meters of ventilation tunnel. The construction of the main entrance, cable, main tunnel, and other structures has been started.


Establishment of crusher plant and batching plant at the project site, testing of construction materials, construction of Bailey Bridge on Trishuli River for the access road, cutting of trees for the construction of the dam and other structures, construction of access road towards search tank are in full swing. At present, 200 workers are employed in the construction site.


The Korean company Dusan has won the contract for the construction of the project in engineering, procurement, and construction model. The Upper Trishuli-1 is the largest hydropower project to be constructed with foreign direct investment for domestic consumption. The promoter of the project, Nepal Water and Energy Development Company, has a stake in the International Finance Corporation, including the World Bank Group, which is owned by the Korean government.

In addition, a maximum of 10 percent share investment has been ensured for the project affected locals. Financial management has been made for the project by raising 70 percent loan and 30 percent equity. The total estimated cost is US 647.3 million (inclusive of construction period interest). Nine international financial institutions have agreed to invest US 453.2 million in the project. The remaining amount is raised from equity.


The project will generate 1.53 billion units of energy annually. Out of the total annual energy generated from the project, 38.75 percent will be generated in winter and 61.25 percent in the rainy season. The electricity generated will flow into the national transmission system at the Trishuli-3B hub substation being constructed by the Nepal Electricity Authority.

The project is considered very attractive for the country’s power system. It is close to Kathmandu Load Center and will receive 104 MW of electricity even in winter when there is high demand. The project will generate 104 MW of stable energy throughout the year. The construction of the project is targeted to be completed by mid-November 2083 BS.
