The Quang Trach - Quynh Luu project spans 226 km, passing through the provinces of Quang Binh, Ha Tinh, and Nghe An. The project includes 463 tower foundation locations, of which 237 are located through mountainous terrain and complex landscapes. Of the 197 spans along the transmission line corridor, 7 spans cross large rivers and lakes, and 15 spans cross national highways. (Photo: Cuong Dao)

The project commenced construction on January 18, 2024, and was approved for commissioning by the investor's acceptance council on August 24, 2024. Photo: Cuong Dao

In Nghe An province, the project, approximately 100km long, includes 202 tower foundation locations and 85 corridor anchor points, passing through 6 districts and towns: Hoang Mai, Quynh Luu, Yen Thanh, Dien Chau, Nghi Loc, and Nam Dan. Photo: Cuong Dao

Trong quá trình triển khai, dự án luôn nhận được sự quan tâm chỉ đạo của Thủ tướng Chính phủ, các bộ, ngành, lãnh đạo Tập đoàn Điện lực Việt Nam. Cùng với đó là sự ủng hộ của các cấp chính quyền nơi có dự án đi qua, sự đồng lòng, chung sức của người dân đã nhường đất cho dự án, đã tham gia hỗ trợ thi công giai đoạn đào đúc móng.

_nda1965(1).jpg — The project also faced difficulties in mobilizing construction workers to erect poles and lay wires due to the tight construction schedule, short implementation time, and the simultaneous construction volume of poles and wires for other large projects. Photo: Cuong Dao

Upon completion, the project will help reduce the load and prevent overloading of existing 500kV transmission lines, ensuring the N-1 criterion, especially when transmission capacity is high along the Central-Northern interface at times when hydropower plants in the North are operating at low levels.
