The 519km 500 kV circuit 3 transmission line stretching from Quang Trach in central Quang Binh province to Pho Noi in northern Hung Yen province was put into operation from late August 27, after more than 7 months of construction, according to a report from the Government News.

Its construction began on January 18, 2024. The project traverses nine provinces and has a cost of around VND22 trillion ($916 million), serving to enhance the transmission capacity of the 500kV power grid from the North Central region to the North. It also raises the transmission capacity from the current 2,200MW to approximately 5,000MW, equivalent to over 20 billion kWh of commercial electricity supply to the North annually.

The project contributes to ensuring electricity supply for the Northern region this year and the following years.
