The project was commenced on 31 August 2021. According to the schedule approved by EVNNPT, the project needs to be completed and energized in the third quarter of 2022. However, because the Ngu Hanh Son 220kV substation has always operated at a high load and is at risk of instability, the Power Transmission Project Management Board urged the contractors and related units to accelerate the construction progress and put the project into operation as soon as possible.
Currently, Ngu Hanh Son 220kV substation has been upgraded from 376MVA to 626MVA (including 2 110kV - 63MVA and 2 220kV - 250MVA units), which helps to increase the ability to supply safe and continuous power for Da Nang city, especially industrial parks and factories to serve socio-economic development and people's needs of power.
