The project is located in Marsyangdi river of Manang and Lamjung District with installed capacity of 125 MW and annual energy generation 892 GWh in average year. The project consist of diversion weir with intake facility to with draw design discharge of 48.7m3/s. There is a surface desilting basin with suitable silt exclusion culvert. Clean water through the desilting basin is conveyed through headrace tunnel of length 3.9km and 4.9m diameter. There is provision of surge shaft at the end of headrace tunnel and water is conveyed to drop shaft of 3m diameter and length of 302.8m which connects to penstock of length 191m. The water through the penstock is trifurcated and fed to the Francis turbine of 41.7 MW rated capacity. The turbine water is again discharged to Marsyangdi River through tailrace tunnel of 4.4m diameter and 165m long. There is open switchyard in front the portal of access tunnel with required facility to transfer voltage to 220kV. The power is planned to be evacuated from switchyard with transmission line of 220kV capacity and 177km length terminating at Butwal hub of NEA.
