The Nyadi Hydropower Project is a run-of-river type project, located in Lamjung District of Western Development Region of Nepal. The entire component from intake to powerhouse are located within the Ward no. 6 of Marsyangdi Rural Municipality, Lamjung District.

The project has an installed capacity of 30 MW and will generate 168.55 GWh of energy annually. The gross head of the project is 333.9 m and design discharge of the project is 11.02 m3/s. The generated power will be connected to a proposed NEA’s Hub (Khudi Hub) that will be constructed at Marsyangdi corridor. An about 14m diversion dam has been designed to construct across the Nyadi River to divert water from intake to underground settling basin and conveys the water through about 4000 m long headrace tunnel and 745 m long penstock pipe. A surface powerhouse has been proposed on the right bank of Nyadi River at the Thulobeshi. About 520 m long adit tunnels which include Adit 1 (Flushing Tunnel), Adit 2 (Naiche Adit), and Penstock Tunnel will be constructed to make 4 headings for excavation and construction of the headrace tunnel. Surge shaft is designed near the end of the headrace tunnel having diameter of 5.0 m and 35 m height.
