The construction of the underground powerhouse and other major structures of the 140-megawatt Tanahun Hydropower Project at Rishing Rural Municipality-1 in Tanahun district has reached its final stage, with works under the project's second construction package now nearly 80 percent complete, according to details provided by Project Chief Shyamji. The update, reported on Friday by Rato Patti and Nepal Press, marks a key phase for the hydropower scheme, whose Package-2 construction is being carried out by China's Sino Hydro Corporation.

Package-2 works nearly 80 percent complete

The second construction package of the Tanahun Hydropower Project covers three major components: the powerhouse, the tunnel and the installation of related equipment. According to the figures shared by Project Chief Shyamji, work across these components has now approached the 80 percent completion mark, placing construction of the powerhouse and other major structures in the final stage.

The main components under Package-2 include:

  • Underground powerhouse: Construction of the project's underground powerhouse, along with its other major structures, has reached the final stage.
  • Tunnel: Tunnel works under the package form part of the scope now close to 80 percent complete.
  • Related equipment: Installation of the equipment connected to the powerhouse and tunnel is also nearing the 80 percent mark.

With the 80 percent threshold reached, the remaining works under Package-2 relate to the completion of these same three components. Project officials have described the powerhouse construction, in particular, as having moved into its concluding phase, a stage that brings the physical structures of the scheme visibly closer to readiness.

An 80 percent completion rate on a package that combines the powerhouse, the tunnel and equipment installation indicates that the bulk of the project's most intensive construction activity has already been carried out. The remaining scope under the package represents the final stretch of this phase of the build.

Sino Hydro Corporation at the helm of Package-2

The Package-2 construction is being executed by Sino Hydro Corporation, a construction company from China. The company's responsibilities under the package span the powerhouse, the tunnel and the installation of related equipment, making its work central to the stage of construction that project officials now describe as nearly complete.

The progress figure announced for the package comes directly from the project leadership. It was Project Chief Shyamji who provided the details on how far the Package-2 works have advanced, and both Nepali media reports on the project cited his account in relaying the near-completion status of the powerhouse, tunnel and equipment installation works.

What the final stage means for the project

The Tanahun Hydropower Project is a 140-megawatt development located in Rishing Rural Municipality-1 of Tanahun district. The underground powerhouse, now in the final stage of construction alongside the project's other major structures, is central to the scheme's 140-megawatt design, as it is the structure with which the installation of related equipment under Package-2 is associated.

The announcement that powerhouse construction is in its final phase therefore stands out as a significant marker of progress for the project as a whole. The key facts of the development can be summarized as follows:

  • Project: Tanahun Hydropower Project
  • Capacity: 140 megawatts
  • Location: Rishing Rural Municipality-1, Tanahun district
  • Package-2 scope: Powerhouse, tunnel and installation of related equipment
  • Package-2 contractor: Sino Hydro Corporation, China
  • Package-2 progress: Nearly 80 percent complete
  • Current status: Underground powerhouse and other major structures in the final stage of construction

Details from the project office and media reports

The completion update originated from the project office, where Project Chief Shyamji provided the details on the status of the underground powerhouse and other major structures. Rato Patti and Nepal Press both carried the announcement, with each report emphasizing that construction of the project's powerhouse is in its final phase and that Package-2 works stand at nearly 80 percent completion.

With the underground powerhouse and other major structures now in the final stage of construction, the Tanahun Hydropower Project's second package has moved decisively toward completion. The remaining works, centered on the powerhouse, the tunnel and the installation of related equipment under Sino Hydro Corporation, now define the distance between the project's current state and the full realization of its 140-megawatt design. Further updates on the progress of these remaining works are expected from the project office as construction advances.
