Energizing the 220kV transmission line project to import electricity from Laos to Vietnam

EVNNPT units coordinate with related units to energize the project.

Completing the project is the most practical action of EVNNPT and NPMB to celebrate the 70th anniversary of the Vietnam Electricity Industry (December 21, 1954 - December 21, 2024).

The 220kV Nam Sum - Nong Cong transmission line project is invested by EVNNPT, managed by NPMB, and operated by Power Transmission Company 1.

The project has a scale of 2 circuits nearly 130 km long with 299 pole positions, and 99 anchorages, going to Nghe An and Thanh Hoa provinces. Of which, the section through Nghe An province is 77.31 km long, including 174 pole foundation positions. The section through Thanh Hoa province is 52.64 km long, including 125 pole foundation positions. The entire route has up to 234 pole foundation positions affected by forests. The project started construction in December 2021.

The 220 kV Nam Sum - Nong Cong transmission line project was energized (noon, December 21, 2024).

This is an urgent project, invested in and built with the aim of importing electricity from the Nam Sum Hydropower Plant cluster (Laos) to Vietnam to meet the growing demand for load of the Northern region's power system. At the same time, it concretizes the commitment between the Party and the Governments of Vietnam and Laos to strengthen energy cooperation.

During the implementation process, the project encountered many difficulties in site clearance, difficult construction terrain, erratic weather, etc. However, with the support of the Government, ministries, branches, EVN, and local authorities where the power line passes through, the project has now been completed and energized to meet the requirements.

The cross-border pole span connects the Vietnam - Laos power system.

The completed project will transmit power capacity from Laos to Vietnam to contribute to ensuring electricity for the North from 2024 and the following years, while contributing to ensuring the N-1 criteria, and improving the reliability and safety of power supply for the regional grid./.
