The 500kV line 3 Quang Trach - Pho Noi project has an estimated total length of about 519 km, passing through many areas from Quang Binh to Hung Yen. The total investment is more than 22,000 billion VND. When completed, the project will increase the capacity of transmitting electricity from the Central region to the North (from the current 2,200 MW to 5,000 MW), contributing to ensuring the power supply for the North, especially in the dry season and minimizing power outages on hot days.
