The Electricity of Vietnam’s National Power Transmission Corporation (EVNNPT) on April 25 held a conference in the central city of Da Nang to review the 20-year operation of the North-South 500kV transmission line.

Chairman of the Vietnam Power Association Tran Viet Ngai said the line’s Circuit 1, stretching nearly 1,500 km from the northern province of Hoa Binh to Ho Chi Minh City, was inaugurated on May 27, 1994.

That was the first time Vietnam had constructed such an extra high voltage line, he said, adding that it had taken two years to build despite other countries saying it would take 8-10 years.

Prof. Tran Dinh Long said the project marks a milestone in Vietnam’s electricity sector as it connects three separate power systems in the north, the centre and the south of Vietnam.

In the past two decades, both circuits of the line have transmitted more than 12 billion kWh per year.

At the event, EVNNPT Deputy General Director Tran Quoc Lam said the firm is working hard to put into use the Pleiku-My Phuoc-Cau Bong 500kV line, which is deemed as the third circuit of the North-South 500kV line.-VNA
