About

The Trishuli Hydropower Station is a peaking run-of-river hydropower plant located in Nuwakot District, Bagmati Province, Nepal. Commissioned in 1967 and upgraded to 24 MW capacity in 1995, it draws water from the Trishuli River via a gravity dam and operates with a balancing reservoir. The project is part of a cascade system, feeding into the downstream Devighat Hydropower Station. It features seven horizontal Francis turbines with a combined rated capacity of 24 MW and an annual design energy generation of approximately 163 GWh. The facility’s infrastructure includes a gravity diversion dam, a headrace tunnel nearly 3.7 km long, steel-lined penstocks, and a surface powerhouse. Owned and operated by Nepal Electricity Authority (NEA), the station is currently undergoing modernization and rehabilitation works during 2024–25 to improve its performance and peaking operations. The project contributes significantly to Nepal’s hydropower supply with a 66 kV transmission line connecting it to the grid.
