Himal Hydro successfully completed this project as the main Civil Contractor, despite the remoteness of the project from the nearest accessible road and the tunnel being run across the Main Central Thrust (MCT). Nepal Electricity Authority is the owner of the project.
This project is also exemplary in generating construction power from flow through the diversion tunnel.
