Sunkoshi Small Hydropower Project (2.6 MW)

Sanima Hydropower, the investor of the project, gave the responsibility of constructing the project to Himal Hydro, which in turn completed it in time without compromising in quality. The power plant is connected to the national grid. Sunkoshi intake is boulder riprap type of intake which seems an appropriate design because of sediments and boulder carrying nature of rivers in Nepal.

It is the first hydropower project of Nepal where GRP pipe is used. The water is channeled into the powerhouse through 2 km long glass reinforced pipe (GRP). The water is led into the approach canal from the intake.
