Trungnam Group has inaugurated the 500KV transformer station and 220/500KV Grid line, and the 450 MW Trung Nam Thuan Nam solar power plant in Phuoc Minh commune, Thuan Nam district of the south-central Ninh Thuan Province.
Ninh Thuan province has been a favourite destination for many renewable energy projects with total capacity up to 2,000MW since 2018. The surge investment in the new energy projects in the province was successful developed due to the State’s policy and mechanism as well as local authorities in supporting renewable energy projects.
According to the National Load Dispatch Centre, 80 solar power plants with total capacity of 4,464MW had been built in the country up to June 30, 2019. These projects, mostly in Ninh Thuan province, were already approved by for supplying power to the national grid. However, the national power grid was seriously overloaded with mass operation of series solar power plants in short term in Ninh Thuan and Binh Thuan provinces. Many already built solar power plants could not supply power to the national grid due to overloaded power transmission. Some plants were forced to cut down their working capacity with an average reduction from 30 per cent to 35 per cent, even 60 per cent in keeping the national grid working safety.
Understanding these difficulties, Trungnam Group invested in improving the national infrastructure of power transmission systems, saving the cost for other renewable energy investors from reducing operation capacity. The Group estimated that the reduction of renewable energy plants in the province will not be fixed at 60 per cent due to poor power transmission, but the figure would increase.
The 500kV and 220/500kV power line project in combined with the 450 MW Trung Nam Thuan Nam solar power plant generates more than 1 billion kWh — an equal of 1GWh power from renewable enegy (the first year will be 1.2 billion kWh), and contribute to ease overloaded power network in Ninh Thuan province va South-central coastal region. Two transformer stations of the project, with total designed capacity of 1,800MVA, in combined with power line network will help improve the operation of the national grid system in the South central region.
