Karuwa Seti Hydropower Project

Narrative Description of the Project:

The project is located in Seti river of Kaski district with installed capacity of 32 MW and annual energy generation of 167.56 GWh in average year. The project consists of diversion weir with intake facility to with draw design discharge of 15.3m³/s. There is a surface desilting basin with suitable silt exclusion culvert. Then the flow will be conveyed by a 3.6km long and 3.4m dia. Headrace tunnel after the desilting facilities. There is provision of surge shaft at the end of headrace tunnel and water is conveyed to drop shaft of 6m diameter and length of 35m. Steel penstock pipe of length 808m bifurcates and conveys the design flow to 3 units of horizontal axis Francis turbines installed in the powerhouse located on the right bank of the river. The turbine water is again discharged to Seti River through tailrace channel of 3.2m X 3.5m size and 65m long. There is open switchyard of approximate area 50m X 40m. The generated power will be evacuated from switchyard through the transmission line of single circuit, 132kV capacity and 9.34km length terminating at Lahachowk substation allotted by NEA.
