Kathmandu, January 14
As the contractors have been delaying in installing penstock pipes in the vertical tunnel of the project, the 456-megawatt Upper Tamakoshi hydropower project is likely to miss its completion deadline.
Nepal Electricity Authority (NEA) has set a project completion deadline of mid-July this year.
However, the unsatisfactory performance of the contractors has raised concerns about whether this deadline can be met.
Neupane informed, however, that the project is still facing hassles related to hydro-mechanical works, especially in installing penstock pipes in the vertical tunnel of the project.
The project had assigned Texmaco Railway Engineering of India to complete the hydro-mechanical works.
However, considering the slow pace of work, Austrian firm Andritz Hydro was brought in, in January of last year to take on part of installing the penstock pipes.
As of now, Texmaco, which is responsible to instal penstock pipes along 373 metres of the vertical tunnel has installed a total of 90
metres of the pipes. Similarly, Andritz Hydro, which is responsible to instal the pipes along 310 metres of the tunnel, has completed installing 190 metres of the pipes so far.
This means a total of 280 metres of penstock pipes have been installed in the tunnel so far, while the contractors are yet to instal pipes along 403 metres of
