Annual Energy Generation 133.432 GWh


Seti Khola Hydropower Project is a run-of-river type project with an installed capacity of 22 MW designed to generate 133.432 GWh energy annually. The project area is located between the elevation of 633 meters and 500 meters above mean sea level. It is in the middle reaches of Seti Khola in Kaski District, Gandaki Province, Nepal. More specifically, the project area is located between longitudes 84004’15″E to 84005’28″E and latitudes 2805’00″N to 28008’05″N. The Project is designed / built by Clean Energy Consultant Pvt. Ltd. The Civil works contract is being implemented by M&A Construction, a construction company that belongs to the Developer’s shareholders.


All the components of the project lie in the right bank of Seti River within Pokhara Metropolitan, Ward No. 33. The project components include the Headworks, Settling basin, Headrace tunnel as well as Headrace pipe, Surge tank, Penstock Pipe, Powerhouse, Tailrace and Switchyard. The Headworks is accessible through a 2 Km long Pitchroad from Gagangauda on Prithivi Highway. Likewise, an all season gravel road 5 km long connects the Powerhouse to Gagangauda Mode independently. Both roads have been widened and upgraded in different sections by the project in coordination with Pokhara Metropolitan. The project has been promoted by Seti Khola Hydropower Pvt. Ltd. (SKHPL) which is a single purpose company established for the development of Seti Khola Hydropower Project.

The Power Purchase Agreement (PPA) for the sale of energy generated from the project has been signed with Nepal Electricity Authority (NEA). The generated electricity will be evacuated through an approximately 1.5 km long 132kV Transmission line to the 132 kV Lekhnath- Damauli Transmission Line between 53-56 no tower of Nepal Electricity Authority (NEA). The company has already acquired Generation License for Construction from Department of Electricity Development (DoED), Ministry of Energy, Water Resource and Irrigation and the project has embarked on construction since April 2021.
