KATHMANDU: The Chilime-Trishuli 220 KV transmission line, designed to transmit electricity from hydroelectric projects on the Trishuli River and its tributaries to the national grid, is now in its final stage of construction.
The last phase involves completing the 28 km transmission line from the Chilime Hub Substation in Thambuchet, Amachhodingmo Rural Municipality of Rasuwa, to the Trishuli 3B Hub Substation in Pahrebensi, Kispang Rural Municipality of Nuwakot.
Currently, the remaining construction work is progressing rapidly with a goal to finish before Dashain.
The construction of the Chilime Hub and Trishuli 3B Hub substations, both crucial components of the project, has been completed.
Of the 76 towers required for the transmission line, 75 have been finished, with only one tower left to complete.
Additionally, five km of the 28 km line remains to be laid, and around 200 workers are on-site to complete this task.
Nepal Electricity Authority’s Executive Director Kulman Ghising, along with Deputy Executive Director Dilghayukumar Shrestha and other high-level officials, visited the site on Saturday.
They emphasized the importance of completing the project before Dashain and instructed the team to adhere to this deadline.
Following discussions with project management, consultants, and contractors, the team decided to expedite the remaining work and closely monitor progress.
The transmission line will carry electricity from the 111 MW Rasuwagadhi and 42.5 MW Sanjen hydroelectric projects, managed by Chilime Hydropower, a subsidiary of the Authority.
Both projects are ready for power generation, intensifying the need to complete the transmission line promptly.
Executive Director Ghising highlighted the significant progress made despite the challenging geographical conditions.
“The construction has reached its final stage after overcoming numerous obstacles in the difficult Himalayan terrain. We urge everyone to make a final push to complete the work before Dashain,” said Ghising.
The remaining tasks include laying a 1,235-meter wire between Tiru in Uttargaya Rural Municipality-1 and Siruchet, with drone technology being utilized for the Mailungkhol section. Preparations for the Mailung crossing have been completed.
Building towers in this region has been challenging due to its rugged terrain, lack of roads, and other logistical issues, including transporting materials and dealing with weather conditions.
Despite these hurdles, significant progress has been made, including the construction of over 20 kilometers of access roads.
Nine towers were built using materials transported manually or by helicopter.
The project also includes a 20 km double-circuit line from Chilime to Mailung and an 8 km multi-circuit line from Mailung to Trishuli 3B Hub.
Looking ahead, a multi-circuit line will be added under the leadership of Korean companies to connect the 216 MW Upper Trishuli-1 hydroelectric project.
This expansion will be partially funded by Upper Trishuli-1, covering 60 percent of the cost.
