Vietnam Strengthens Grid With Transformer Upgrade At Pho Noi

The Pho Noi 500 kV transformer station in Hung Yen province has achieved a major upgrade, marking a significant step in Vietnam’s energy infrastructure. The energization was completed on March 25, 2026, with EVNNPT and its project partners overseeing the successful commissioning.

Project Significance
The upgrade enhances the station’s ability to handle higher loads, addressing previous capacity strains where utilization often exceeded 90%. By boosting capacity to 1,800 MVA, the project ensures reliable power transmission to industrial hubs and urban centers across Northern Vietnam.

Operational Impact
The project was implemented within the existing station premises, avoiding land expansion. Power Transmission Company No. 1 will operate the upgraded facility, ensuring seamless integration into the national grid. This development is expected to reduce overload risks, improve efficiency, and support Vietnam’s long-term energy security.

Key Highlights

• Pho Noi 500 kV station upgraded to 1,800 MVA
• Commissioned successfully on March 25, 2026
• Capacity strain previously reached up to 97% utilization
• Project executed without expanding station land area
• Strengthens power supply for Northern Vietnam’s industries and households
