Upper Trishuli 3B Hydropower Project is in full gear, with a 58 percent completion rate


Kathmandu, March. 9: Work on the 37 MW Upper Trishuli 3B Hydropower Project under construction in Rasuwa and Nuwakot under the People’s Hydropower Program has gained momentum.
The overall physical construction progress of the Upper Trishuli 3B Hydropower Project, which has been hit by the Covid-19 epidemic, has reached 58 percent so far. Work is in full swing with the aim of completing the construction of the project by September 2023 .

The construction of the project, which was in full swing, was halted for about 15 months as Chinese workers, who had gone to their homes in the second week of January 2020 to celebrate the New Year, could not return due to Covid-19 and bring equipment and materials from China. The construction of the project was resumed only from April 2021, but the work was again affected for about three weeks due to the second and third wave of Covid-19. Also, construction was affected by the discovery of a much weaker rock than previously thought in the main tunnel. Contractor Chinese company Suifa ANHE Group Co., Ltd. is currently constructing main structures including intake, main tunnel, power house and so on.

Managing Director of Trishuli Hydropower Company Limited, the promoter of the project, Mohan Prasad Gautam said that 2865 meters of the main tunnel with a length of 3805 meters has been dug.

“Concreting of structures has started after completion of excavation of surface power house, work is being done with the aim of concreting the first phase by connecting electromechanical equipment and parts by next May,” said Gautam. “As the customs checkpoints with China have not been fully opened yet, the contractor company has not been able to transport the construction equipment and materials in the production and packaging stage to China and bring them to the construction site.” We have received information that they will be released from the customs soon. ‘

The contract agreement was signed with Suifa ANHE Group Company on 12 Feb 2018 for the construction of the project in Engineering, Procurement and Construction (EPC) model. The Contractor Company will design, construct, connect and operate all the civil, electromechanical and hydromechanical side structures and equipment of the project. As the 60 MW Upper Trishuli 3A Hydropower Project is a cascade project constructed by the Nepal Electricity Authority, the Upper Trishuli 3B will not have to build dams, descender and other structures. The gate required to send the water released from the Upper Trishuli 3A power house to the tunnel of the project has been connected.

The electricity generated will be transmitted to the national grid through the existing Samundar Tar-Trishuli 3B hub .
