The 500kV circuit-3 power transmission line linking Quang Trach in the central province of Quang Binh and Pho Noi in the northern province of Hung Yen was officially put into operation on August 29.
Attending the inauguration ceremony saw the presence of Prime Minister Pham Minh Chinh at the main venue in Hung Yen, Deputy Prime Minister Tran Hong Ha at the venue in Thai Binh province, Deputy Prime Minister Le Thanh Long at the venue in Thanh Hoa province, and Deputy Prime Minister Ho Duc Phoc from Ha Tinh province.
The 519km-long line has an investment capital of over 22.3 trillion VND (896.8 million USD), comprising four sections, including Quang Trach - Quynh Luu, Quynh Luu - Thanh Hoa, Thanh Hoa - Nam Dinh 1 thermal power plant, and Nam Dinh 1 thermal power plant - Pho Noi.

The 500 kV transmission line project from Nam Dinh 1 Thermal Power Plant to Thanh Hoa was operational on June 30; the Nam Dinh 1 Thermal Power Plant - Pho Noi and Quynh Luu – Thanh Hoa sections completed on August 18; and the Quang Trach - Quynh Luu section on August 27.
These are critical and urgent power transmission projects with a crucial role in increasing the transmission capacity through the 500 kV system from Central to Northern Vietnam from the current 2,500 MW to 5,000 MW. They will help improve the stability of the power system, boost electricity supply for the north in 2025 and the following years, and reduce the risk of overload and congestion in existing 500 kV lines and stations, thus contributing to ensuring national energy security./.
