The equipment was unloaded at Vinh Tan Port in the neighbouring province of Binh Thuan.
In addition to a 450-megawatt solar farm, Trung Nam will also build the 500kV Thuan Nam Substation and 17 kilometres of transmission lines to connect with the national power grid.
As the heart of the substation, the two transformers weigh a total of 1,500 tonnes, have a combined power of 1,800 megavolt-amperes and were produced by the German industrial equipment manufacturer Siemens.
The Thuan Nam solar farm and its transmission lines are an urgent project designed to power Ninh Thuan Province and the broader central coastal region.
With a total cost of VND12 trillion (about US$513.7 million), the project is scheduled for completion by the end of the year.
Trung Nam Group is currently the top investor in the field of renewable energy in Vietnam.
