These are two component projects of the circuit 3 500kV transmission line project from Quang Trach to Pho Noi.
Accordingly, the National Power Transmission Corporation (EVNNPT) has been appointed as the project investor.
Quang Trach - Quynh Luu 500kV transmission line project has a length of about 225.5km with the starting point at the 500kV distribution switchyard of Quang Trach Power Center (Quang Binh province) and the ending point at point D1 about 300m from Quynh Luu 500kV substation (Nghe An). The project passes through the provinces of Quang Binh, Ha Tinh, Nghe An; with a total investment cost of about VND 10,110.915 billion.
Quynh Luu - Thanh Hoa 500kV transmission line project has a length of about 91.8km with the starting point at point D2, about 300m from Quynh Luu 500kV substation (Nghe An) and the ending point at Thanh Hoa 500kV substation. The project passes through two provinces of Nghe An and Thanh Hoa; with a total investment cost of about VND 4,116.027 billion.
The project implementation duration is 40 months, from 2023 - 2025 (with the targeted completion time in June 2024).
Both projects aim at increasing the transmission capacity of the existing 500kV transmission lines to ensure power supply to the North, especially when the transmission capacity trend is high in the Central - North direction due to the high load growth rate of the Northen region. At the same time, they will relieve the load on the existing 500kV transmission lines to ensure N-1 criteria, especially when hydropower plants in the North have low generation; Increasing stable reserves on the North - Central interface, combined with the remaining component projects of the circuit 3 500kV transmission line project from Quang Trach to Pho Noi, contributing to creating a strong connection from the power generation centers in the North Central region to the load center in the North; serving as an important basis for safe, reliable, stable and optimal operation of the power system, contributing to reducing power system operating costs; Transmitting the energy of thermal power plants as well as renewable energy plants in the North Central region into the national power system, supplying electricity to the load center in the North.
In these decisions, the Prime Minister has approved the policy of converting the use purposes of the two projects; At the same time, the Prime Minister has requested relevant ministries, agencies, local authorities, the Commission for Management of State Capital at Enterprises, and Vietnam Electricity to undertake tasks and responsibilities under their management authorities and coordinating with the project investor to implement the project effectively.
