The project is feasibility study for development of run-off river hydropower (39 MW) from the tail race of Upper Bhote Koshi-I Hydroelectric Project (installed capacity 36 MW) located in Sindhupalchowk District. Main project features include head pond (32mx13x13 h), headrace tunnel (3.08 km), surge tank, surface power house, switchyard, transmission line 132 kVA (0.384 km). Annually the project will generate energy of 238 GWh. The project will cost US$ 60.19 million.

The scope of work included (i) Techno-economic Feasibility Study (ii) Initial Environmental Examination and (iii) Preparation of tender document. The Techno-feasibility study was carried out in coordination with existing Upper Bhote Koshi Hydroelectric Project operating system at the upstream and proposed Middle Bhote Koshi Hydroelectric Project at the downstream. Initial Environmental Examination was carried out in accordance with Environmental Protection Rules, 1997 (amendment 1999 and 2008).
