Successful Energization of Nho Quan - Phu Ly Section: A Milestone in Vietnam's National Power Transmission System
At 12:30 AM on July 17, 2026, the National Power Transmission Corporation (EVNNPT), in coordination with the Project Management Board for Northern Power Projects (NPMB), the National Power Dispatching Center, and related units, successfully completed the energization of the Nho Quan - Phu Ly transmission line section. This significant milestone is part of the 500kV/220kV Nho Quan - Phu Ly - Thuong Tin project, contributing to enhanced reliability and stability of the northern power system.
Background and Significance of the Project
Vietnam's national power transmission system faces numerous challenges in meeting growing demand, particularly in rapidly industrializing and urbanizing areas. Investment in new transmission line construction is a critical solution to ensure national energy security and promote socio-economic development.
The 500kV/220kV Nho Quan - Phu Ly - Thuong Tin project was implemented to address the overload situation of existing transmission lines, connect new power sources to the national grid, and improve power transmission capacity from northern to central Vietnam.
