Kathmandu. The construction of the Chilime-Trishuli 220 kV transmission line, which is considered important for the flow of electricity produced by the hydropower projects under construction and to be built in the Trishuli river corridor and its tributaries, has reached its final stage.
The final phase of construction of 28 km transmission line from Chilime Hub Substation located in Thambuchet, Amachhodingmo Rural Municipality of Rasuwa to Trishuli 3B Hub Substation located in Pahrebensi of Kispang Rural Municipality of Nuwakot is underway.
The rest of the transmission line construction work is being completed and put into operation before December. Under the Chilime-Trishuli 220 KV transmission line project, the construction of 220/132/33 KV Chilime Hub and Trishuli 3B Hub substations have been completed.
Out of the 76 towers on the transmission line, 75 have been completed. One tower connection work is in final stage. Out of the total 28 km of transmission line, only five km of wire is yet to be laid. Two hundred workers are deployed to connect the tower and pull the remaining wires.
Nepal Electricity Authority’s Executive Director Kulman Ghising, Deputy Executive Director of Broadcasting Directorate Dilghayukumar Shrestha and other high-level team has on-site monitoring of the transmission line construction work on Saturday and fixed the deadline to be able to work before Dasain.
After discussions between the project management, consultants and contractor companies, the team has decided not to delay the construction work, added workers to speed up the work, and has instructed the team to set a schedule for completing all the remaining work and perform the work accordingly. The team also monitored the place where the final tower was being connected and where the wires were yet to be pulled.
The power of the 111 megawatt Rasuwagadhi and 42.5 megawatt Sanjen hydropower projects built under the leadership of Chilime Hydropower, a subsidiary company of the authority, will be connected to this transmission line. Both projects have been completed and are in the stage of power generation. Because of this, the authority is under pressure to complete the transmission line construction as soon as possible.
The Executive Director of the Authority, Ghising, said that the transmission line under construction in the geographically very dangerous and difficult Himalayan region has now been completed after continuous efforts. “Due to the failure of this line, the two hydropower projects are not able to start generating electricity. The construction of the line has reached its final stage by overcoming the difficult geographical conditions. Let us all make the last effort to complete the rest of the work and complete the construction before the end of the decade,” Ghising said.
From Uttargaya rural municipality-1 Tiru to Siruchet of the same ward, a wire has to be stretched for a length of 1,235 meters. The wire will be pulled using drones in the section above Mailungkholah. All preparations for Mailung crossing have been completed.
A tower has to be built in a geographically very dangerous and difficult mountainous area, because it is crowded and there is no road, so stones, sand, tower materials, water have to be carried by people or carts, floods, poor performance of contractors, problems of land use in forest areas, obstacles from locals, covid- Due to 19 etc., the construction of the project has been affected. Since the construction site is located in the Himalayan and hilly areas, the weather is also having an adverse effect on the construction of the line.
The transmission line has been constructed in an area ranging from 680 to 2600 meters above sea level. A total of 33 towers had to be built in places where there was no access road. A separate access road has been constructed to reach the place. The project has built more than 20 kilometers of access roads for the construction of the line.
9 towers have been built by transporting construction materials and tools from Khachhad and people. Two towers have been built by transporting materials by helicopter. Under the transmission line, Chilime-Mailung section 20 km double circuit and 8 km four 9 multi-circuit line up to Mailung-Trishuli 3B hub have been constructed.
Under the leadership of Korean companies, a multi-circuit line is going to be made to connect the power of the 216 megawatt upper Trishuli-1 hydroelectric project. Upper Trishuli-1 will bear 60 percent of the cost of constructing the multi-circuit line.
A contract was signed with the Chinese company Pinggao Group of Companies in October 2074 for the construction of transmission lines and substations. The contract agreement was implemented in December 2074. Rasas
