About the Project

Rasuwagadhi Hydroelectric Project

The company is developing Rasuwagadhi Hydroelectric Project having capacity of 111 MW. It is located in Gosaikunda Rural Municipality of Rasuwa district, Nepal. The project is accessible through Kathmandu – Trisuli – Somdang road at a distance of 130 km to the north of Kathmandu to reach Syabrubesi and then around 16 km from Syabrubesi to the project site at Rasuwagadhi. The Company has managed debt and equity structure in the ratio of 60:40 for financing the project.

General Overview

The project is a run-of-river type with capacity of 111 MW. The annual energy generation is 613.875 GWh from the available gross head of 167.9 m and design discharge of 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 is 4185 m up to the surge tank. Tail water from the powerhouse will be released to main river course through 659.3 m long tailrace tunnel in the downstream of powerhouse site. The project is located in Gosaikunda Rural Municipality, ward no. 1 and 2 (Thuman and Timure) of Rasuwa district.
