The Simbuwa Khola is a left bank tributary of the Tamor River and has a steep gradient from its origin to its confluence with the Tamor River. The scheme has an installed capacity of 70.3 MW and is being developed as a run-of-river type high head hydropower project with a gross head of 901.50 m and design discharge of 9.25 m3/s at a 40.16% flow exceedance level. The annual energy generation will be 401.68 GWh and this will be evacuated through the 3.1 Km long 220 kV double circuit transmission line to Ghunsa pooling station and then through the Ghunsa - Dhungesanghu transmission line.
The project area can presently be accessed from Bhadrapur via Charali on the East-West Highway through a 242 km long, black-topped highway (HO-7) up to Phungling. The project area is located at about 45 km from Phungling Bazar, the headquarters of Taplejung district and the powerhouse site is located near Tamewa village.
