Based on the Feasibility Study, the installed capacity of the project is 14.3 MW with the design discharge of 3.53 m³/s, corresponding to 40% exceedance flow. The catchment area of the Project is 72 km² and the gross head is 495.5 m. The 25.50 m long weir has its crest level at 2049.00 m above mean sea level (amsl). The maximum height of weir crest from its original ground level is 5 m which diverts the required flow to the Intake.

One undersluice gates maintain the design water level for intake and flush excessive deposits deposited in front of the intake area. Intake comprises of 2 openings to withdraw the design discharge. The flow from the Intake is conveyed to the gravel trap and successively towards settling basin via an approach pipe of about 15.48 m length. Settling basin designed with 90% trap efficiency (60 m long and 27.80 m length in inlet transition) passes the clean water into the headrace tunnel. A 1,736 m long headrace tunnel with excavated diameter of 2.8 m passes the design discharge to the penstock.

Proposed penstock is of 1.2 m (internal diameter) up to the branching length of about 1172.378 m after which four penstock pipes of internal diameters ranging 0.630 m to 0.85 m supply the water to the Powerhouse. Powerhouse is 40.6 m long and 14 m wide with the tail water level at Turbine Axis level1533.5 m amsl. 2 units of horizontal axis Pelton turbines each of 7.5 MW capacity is proposed to generate the designed output of 14.3 MW. After the power generation (non-consumptive use), the tail water is discharged back to Mailung River.

The generated electricity is supplied through a 11 km long 132 kV single circuit transmission line (with 28 towers) to Trisulli 3B Hub Substation which is being constructed by Nepal Electricity Authority (NEA). The estimated annual energy generation as per the PPA is 79.67 GWh.
