Successfully energized the 500kV Monsoon – Thanh My transmission line project to serve electricity import from Laos

ANTD.VN - Power Project Management Board 2 (under Vietnam Electricity Group - EVN) said that at 22:43 on January 23, 2025, the 500kV Monsoon - Thanh My transmission line project (section in Vietnam) was successfully energized.

500 kV Monsoon-Thanh My transmission line is constructed on difficult and complex terrain.

This is a key transmission grid project, serving the import of electricity from the Monsoon wind power plant (in Laos) to Vietnam, adding 600MW of electricity to the national power system in the 2024-2025 period.

The 500 kV Monsoon - Thanh My transmission line project (section in Vietnam) is invested by Vietnam Electricity Group (EVN), and Power Project Management Board 2 (EVNPMB2) is assigned as the investor's representative.

The part of the project located in Vietnam is built in Nam Giang district, Quang Nam province with a length of about 44.71 km, the total investment of the project is more than 1,100 billion VND.

This is a double-circuit line project, connecting from the Monsoon Wind Power Plant cluster (in Laos) to the 500 kV Thanh My transformer station in Quang Nam province.

The project started on September 30, 2023, overcoming many difficulties and challenges in converting forest use purposes, site clearance, difficult mountainous terrain plus harsh weather in the area, but thanks to the determination of the construction units on the site and the strong direction of EVN/EVNPMB2, the project has completed the work according to the approved design with the volume of 90/90 concrete foundation positions completed, 90/90 steel columns completed and 28/28 anchorage spaces completed.

The project part in Vietnam was completed 40 days ahead of the power generation milestone of the Monsoon wind power project (in Laos, expected to be completed in early March 2025).

The 500kV Monsoon - Thanh My transmission line has the capacity to transmit a maximum capacity of up to about 2,500MW, contributing to improving the operational capacity of the national power system through importing electricity from Laos.

In the near future, after the Monsoon wind power plant project (Laos side) is completed, this power line project will receive imported electricity from Laos with a capacity of 600MW, with an expected average annual electricity output of about 1.7 billion kWh.
