Khanikhola -1 Hydropower Project is a run of the river project located in Marbu Village Development Committee, Dolakha District with the hydropower intake located at the highest elevation of 3338 m in Nepal . The construction was initiated in 2011. Greenlife Hydropower Ltd. and manages the overall construction of the project. The civil, hydro-mechanical and electromechanical work is 90 % complete and is in the last phase of completion with installation of EM and final concreting. During the last 11 years natural disasters including the frequent flood and April 2015 earthquake as well as political instability in the country has caused a major impact which consequently led to the delay in project execution. These unexpected calls were dealt cautiously and carried further.
