The main scope of work includes: the transfer of 900 MVA 500 kV transformer from the 500 kV Son La Substation Upgrading project to the 500 kV Hiep Hoa  substation for installation, testing and calibration.   

The expected time for power cut to replace  transformer AT1 of 500 kV Hoa Hiep substation  is 12 days. However, under the close direction of PTC1 leaders, the monitoring of the progress of the PTC1 functional divisions and the efforts made by the contractors, the duration of performance was  9 days, 3 days  ahead of the plan.
