Bac Giang - Lang Son 220 kV transmission line project has a total investment cost of VND 816.457 billion; Lang Son 220 kV substation has a total investment cost of VND 240.245 billion. These projects are invested by the National Power Transmission Corporation (EVNNPT) and financed by the German Reconstruction Bank (KFW) and by EVNNPT’s equity.

After completion, the projects will meet the demand for load growth of Lang Son province and its neighboring areas, creating a bond in the regional transmission network, strengthening the safety and reliability of power supply in the Northern region. In particular, Bac Giang - Lang Son 220 kV transmission line is a double circuit line, about 101.6 km long, from the existing Bac Giang substation to Lang Son 220 kV substation. Lang Son 220 kV substation is built semi-outdoor, with a capacity of 2 x 125 MVA. In this phase,  a 125 MVA substation will be installed first.

It is scheduled that the projects will be put into operation in the second and third quarters of 2019.
