Ngu Hanh Son 220kV substation has been upgraded to 626MVA

On 6 March 2022, the Power Transmission Project Management Board - under the National Power Transmission Corporation (EVNNPT) coordinated with relevant units to energize the project to increase the capacity of Ngu Hanh Son 220kV substation (Da Nang City).

Ngu Hanh Son 220kV substation has just added a 220kV - 250MVA transformer

The project is invested by the National Power Transmission Corporation (EVNNPT), with a new installation scale of 1 220kV - 250 MVA transformer; at the 220kV side, it is installed with 1 isolator, 1 support porcelain unit; at the 110kV side, it is installed with 1 bay; added with panel cabinets, completed the station protection control system for new installations; connected SCADA signal of the newly-installed transformer to Central Power System Dispatch Center (A3), and so on.

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.
