Simultaneously implementing projects on 500kV transmission line circuit 3 from Quang Trach to Pho Noi

On January 18, in the provinces of Ha Tinh, Nghe An, Thanh Hoa and Thai Binh, Vietnam Electricity (EVN) and the National Power Transmission Corporation (EVNNPT) organized a ceremony to commence construction of all sections of the 500kV transmission line circuit 3 from Quang Trach (Quang Binh) to Pho Noi (Hung Yen).

Projects under construction include Quang Trach - Quynh Luu 500kV transmission line, Quynh Luu - Thanh Hoa 500kV transmission line, Thanh Hoa 500kV substation, Nam Dinh I TPP - Pho Noi 500kV transmission line. Previously, at the end of October 2023, EVNNPT started construction of Nam Dinh I TPP - Thanh Hoa 500kV transmission line.

High determination, great effort

The 500kV transmission line circuit 3 from Quang Trach to Pho Noi has a total length of about 519km, passing through 211 communes and wards of 43 districts and towns in 9 provinces including Quang Binh, Ha Tinh, Nghe An, Thanh Hoa, Ninh Binh, Nam Dinh, Thai Binh, Hai Duong, Hung Yen. The total number of tower foundations is 1,179. The total investment cost is about VND 22,000 billion.

The project has important significance in enhancing the capacity of the North-Central 500kV transmission grid, contributing to ensuring electricity supply for the North at present and in the coming years. At the same time, improving the operational stability of the national power system, contributing to enhancing power transmission from power sources in the North Central region to load centers in the Northern region.

In addition, the project contributes to reducing the risk of the full and overloaded status of the existing 500kV transmission lines, ensuring N-1 criteria, especially when the transmission capacity is high at the North-Central interface at times when the hydropower plants in the North have low generation output.
