Nepal Electricity Authority (NEA) has implemented a project to develop the Amarpur-Dhungesanghu 132 kV double circuit transmission line spanning from Amarpur substation at Hilihang Rural Municipality, Panchthar to Dhungesanghu substation at Maiwakhola Rural Municipality, Taplejung.

This transmission line aims to connect the 132-kV Kabeli corridor (Damak substation: Lakhanpur in Jhapa to Amarpur substation) and the 220 kV-Koshi corridor (Inaruwa substation in Sunsari to Dhunge Sanghu). Under the Koshi corridor, the Basantapur-Inaruwa section has already come into operation while the construction of Basantapur-Dhunge Sanghu section has neared the final phase. The Kabeli corridor is already under operation.

The foundation stone laying ceremony for the Amarpur-Dhunge Sanghu transmission line was observed on February 5. Under this, 67 towers need to be developed for around a 19-kilometer transmission line.

According to Project Chief Anup Gautam, the development of the transmission line would enhance reliability over the national grid in the western Nepal, strengthening the power supply capacity.

Power to be generated from projects based on Tamor River sources will be connected to the national grid though the Dhungesanghu substation.

The project commenced in fiscal year 2019/20 at an investment of around Rs 1.20 billion by the government. The contract for constructing the transmission line was signed in 2022. Under the project, two line bays will be constructed at Amarpur and Dhungesanghu substation.

In addition to this, 11 kV structures would be constructed at Dhungesanghu substation for the supply of electricity locally. The contract for the construction of the line bays and the 11 kV structures would be signed in the current fiscal year. The target is to complete all the works under the project within the fiscal year 2024/25.
