The 500kV power transmission line circuit 3 project has a total length of about 519 km; the total investment is about 22,356 billion VND. The project consists of 4 component projects: Quang Trach - Quynh Luu; Quynh Luu - Thanh Hoa; Thanh Hoa - Nam Dinh 1 Thermal Power Plant and Nam Dinh 1 - Pho Noi Thermal Power Plant. The component projects will start construction in October 2023 and January 2024.

The project has an excavation volume of more than 2.5 million m3, using more than 705,000 m3 of concrete, nearly 70,000 tons of foundation steel; the total volume of steel column erection is 139,000 tons; pulling a total of nearly 14,000 km of various types of conductors.

This is a key, urgent project of great significance to increase the power transmission capacity through the 500kV system from the Central to the North with a capacity of 2,500MW at present to 5,000MW, improve the stability of the power system operation, increase power supply to the North in 2025 and the following years, reduce the risk of overloading and overloading of existing 500kV lines and stations, and contribute to ensuring national energy security.

On the evening of August 27, 2024, the National Power Transmission Corporation (EVNNPT), the Central Power Project Management Board (CPMB) coordinated with relevant units to successfully energize the 500kV circuit 3 transmission line project, Quang Trach - Quynh Luu section, thereby connecting the entire 500kV circuit 3 transmission line from Quang Trach (Quang Binh) to Pho Noi (Hung Yen).

Prime Minister: Inauguration of 500kV line 3 on the occasion of National Day this year On the afternoon of August 13, Prime Minister Pham Minh Chinh chaired an online meeting with the two provinces of Ha Tinh and Nghe An on the implementation status of the 500kV line 3 project from Quang Trach to Pho Noi.
