SKKHPP, Super Kabeli Khola Hydropower Project
Project Overview
A run-of-river plant on the Kabeli Khola
SKKHPP is a 12 MW Run-of-River (RoR) hydropower project located in Sirijangha Rural Municipality wards 6, 7 and 8 of Taplejung District, Koshi Province. It is situated on Kabeli Khola, a major tributary of the Tamor River, approximately 253 km northeast of Kathmandu (aerial distance).
Originally conceived as the cascade component of the Super Kabeli Khola-A Hydropower Project (13.5 MW) developed by Snow River Ltd., the project was later developed as an independent hydropower project. Developed by Hilton Hydro Energy Limited, it commenced commercial operation on Chaitra 02, 2081 BS.
Latitudes 27°25'09"N – 27°27'24"N · Longitudes 87°52'33"E – 87°54'02"E
Design discharge of 8.6 m³/s during the wet season

Major components
The project comprises the following major structures and facilities, designed for safe and efficient operation in the Himalayan terrain.
Intake & Gravel Trap
Captures water from the river while removing coarse sediment before conveyance to the settling basin.
Settling Basin & Headpond
Removes fine sediment, ensuring clean water reaches the headrace and turbines for long-life operation.
Headrace Pipe & Tunnel
Conveys water from the settling basin to the surge tank through a combined pipe and tunnel alignment.
Surge Tank
Absorbs hydraulic transients and water-hammer effects to protect the waterway and turbines.
Penstock & Shafts
Surface penstock pipe with vertical and horizontal shafts deliver pressurised water to the powerhouse.
Powerhouse & Switchyard
Surface powerhouse near the Kabeli–Rate Khola confluence, with two horizontal-axis Francis turbines and adjacent switchyard.
Control Room
Monitoring and control systems ensuring safe, efficient operation of the generating units.
Tailrace
Discharged water flows directly into the downstream Kabeli-3 Cascade Hydropower Project, optimising cascade utilisation.
Estimated net annual energy
Total: 73.12 GWh per year.
Wet season: 60.86 GWh
Dry season: 12.26 GWh
Two horizontal-axis Francis turbines at the powerhouse.
Integration with the national grid
Generated electricity is evacuated via a switchyard adjacent to the powerhouse.
~1 km 132 kV single-circuit line to the LILO point.
~25 km combined 132 kV line to NEA Amarpur (Kabeli) Substation.
Energy integrated into the Integrated Nepal Power System (INPS).
