Trungnam Group then acceleratory finished legal treatment and also fund as well as manpower for swiftly commencing the project through days and night working shifts in turning over the project in time.

Treatment a location on 557.09 ha including 17km power transmission line from Phuoc Minh neighborhood in Thuan Nam district to Vinh Tan commune of Tuy Phong district of Ninh Thuan Province, Trungnam Group had dealt with the building and construction timetable from May of 2020 to the 4th quarter of 2020.

With a target of finishing the project in 102 days, Trungnam Group had actually finished land clearance procedure in 45 days with the tough working days from 8,000 labourers and also engineers in turning over the project as proposed time of conclusion.

On the celebration of launch of the project, Chairman of Trungnam Group, Mr. Nguyen Tam Thanh was honourly awarded the Labour Order, Second Class from the State for finishing the solar energy plant and also power transmission project, contributing to the development of renewable resource project in Ninh Thuan Province specifically, as well as to the training course of the country's social republic as well as support.

Trungnam Group additionally significantly added to aid regional community as a function and also obligation of a potential financier in Ninh Thuan Province. The Group, in co-operation with the provincial Fatherland Front, Thuan Nam common people's committee and also rural association of poor patients, had actually given away 102 residences worth 5.1 billion Vietnamese dong to poor homes in the district throughout construction of projects here.
