About Project

The company has aimed to develop Rasuwagadhi Hydroelectric Project having capacity of 111 MW. It is located in Rasuwa district, Bagmati Zone of Central Development Region. The project is accessible by the Kathmandu -Trisuli - Somdang road at a distance of 130 km to the north of Kathmandu to reach to Syabrubesi and then around 16 km from Syabrubesi to the project site at Rasuwagadhi. A 50:50 debt-equity structure will be employed for financing this project.

General Overview
The design discharge of the project is 80m3/sec in Q40 exceedance of time. The headworks site is located about 400 m downstream from the confluence of Kerung khola and Lende khola which are the Boundary Rivers of Nepal and China (Tibet). The total headrace tunnel length of the project is 4196 m up to the surge tank. Tail water from the powerhouse will be released to main river course through 598.55 m long tailrace tunnel in the downstream of powerhouse site. The Headwork site of the project is located on the Thuman and Timure VDC at Rasuwagadhi, whereas all other project components lie in Thuman VDC. The project is basically a run-of-river type scheme having the capacity of 111 MW and the annual energy generation is 613.875 GWh with the available gross head of 167.9 m.
