EVNNPT has completed energizing power projects including: Hiep Hoa - Dong Anh - Bac Ninh 2 500 / 220 kV transmission line (from Hiep Hoa 500 kV Substation to Dong Anh 500 kV Substation); AT1 500/225/35 kV - 900 MVA transformer under Dong Anh 500 kV Substation and connecting branch project; AT3 220/110/22 kV – 250 MVA transformer under Dong Anh 220 kV Substation project.
The projects when coming into operation will relieve the loads of Hiep Hoa 500 kV, Van Tri 220 kV and Bac Ninh 2 220 kV Substations in the context that electrical loads in the North and in Hanoi normally critically go up in the hot and sunny summer, concurrently they will create a 500 kV loop for Hanoi’s and the Northern power grids, enhance safe and stable operation and reliability of the power system.
These projects are invested by EVNNPT, managed and implemented by the Northern Power Project Management Board - NPMB (under EVNNPT), and will be transferred to Power Transmission Company 1 for operation upon project completion.
