Chameliya Hydroelectric Project
Chameliya Hydroelectric Project under joint funding of GoN, NEA and Korean loan was started in 2007 and is scheduled to be completed in March 2016. The site is located at Sikhar VDC, Ward No. 4, Balanch of Darchula District.Theplantcapacityis30MWwithaverageannual energy generation of 184.21 GWh. Even with numerous problems, the project has achieved 94% progress so far towards civil works, 99.8% of the dam construction works has been completed. Similarly, 99.1 % of intake, 100% of connecting tunnel, 100% of desanding basin, 94.1% of adit tunnel and 99.1% of the headrace tunnel (excluding squeezing portion) has been completed.
The progress of power house, surge tank, penstock and tail race construction stands at 99.9%, 70.6%, 63% and 99.8% respectively. The headrace tunnel encountered the squeezing problem of maximum 40% (in diameter) for a length of 843.00m. .The treatment for this squeezing has been completed in 615m stretch. Another major problem faced by the project has been the excessive weak geological condition in the vertical shaft penstock forming the cavity with debris flow. The progress of Vertical shaft is 36 m out of 72m.
The embedded parts for powerhouse have been installed. Installation of two draft tubes with all accessories has been completed. Similarly installation of turbines has also been completed. Most of hydro-mechanical and electro-mechanical equipment are delivered to site. All of tower foundation works and tower erection works of 132 kV transmission line works have been completed. 122.2 km out of 131 km stringing works have been completed. So far 92.2 percent of total electromechanical/hydro mechanical/transmission line works has been completed. A total expense of project till now is Rs. 12.5 billion. This project will provide power in the far western Nepal and will enhance economic development in the region
