Khopasi Hydro Power


Khopasi Hydropower Station is the third hydropower station which was constructed in Nepal. It is the first megawatt capacity hydropower station in Nepal. It is a run-of-the-river hydroelectric plant on the Roshi Khola river. This power station is located at Khopasi, Kavre district, 35 km east of Kathmandu and 7 km south-east from Panauti Bazar.
It was built in 1965 with the assistance from then Soviet
Union at a cost of NRs 27 million. It has a capacity of 2.4 MW, from 3 units of 0.8 MW each and annual design generation of 6.97 GWh. The Project
was designed for operation of only two units at a
time with third unit as a standby. Open canal of
3,721 m long with discharge of 3.2 cu. m/s from
headwork to reservoir has seven outlet gates
for irrigation in the vicinity of Khopasi.
After the major improvement activities accomplished in
2018/019, Panauti Hydropower Station is
generating maximum annual energy which the
power plant had not been able to do since the last
11 years.
