Trungnam Group launches the largest solar farm in Vietnam amid renewables drive

HO CHI MINH CITY,Vietnam,Oct. 13,2020 -- Trungnam Group officially inaugurated the500KV transformer station and 220/500KV Grid line,and the 450 MW Trung Nam Thuan Nam solar power plant on October 12th,2020 in Phuoc Minh commune,Thuan Nam district of the south-central Ninh Thuan Province. It's a magnificent event and key project in celebration of the 14th Ninh Thuan provincial Party's Congress,2021-2025 terms.

Solar power plant Trung Nam- Thuan Nam 450MW

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.

The reduction of operation capacity at some plants created many difficulties for investors in reimbursement and operation cost as well as funding for expansion of investment.

The overloaded power transmission system in Ninh Thuan clearly unveiled the insufficiency of synchronous investment in the national grid infrastructure and at locals,thus resulting in insufficiency of synchronous investment at local and limit the development of renewable energy projects.

Despite of efforts from EVN in improving the national grid and power transmission system over past years,slow administrative procedure and land clearance at locals had delayed the commencing construction of grid projects. While renewable energy projects including solar power plants need only six months to finish,a 220KV or 500KW power transmission project would take from three to five years to complete.

Knowing the difficulties in development of power transmission projects,Trungnam Group decided to invest 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.

As the top leading investor in renewable energy in Ninh Thuan province,Trung Nam drastically proposed an investment of the 500KV transformer station and 220/500KV Grid line and the 450 MW Trung Nam Thuan Nam solar power plant with technical supports and encouragement from the provincial people's committee and EVN.

Following the proposal,Trungnam Group was approved as an investor of the 500KV transformer station and 220KV/500KV power transmission system,in combined of a 450 MW solar power plant under the document No 831/UBND-KTTH sealed on March 18th,2020,and the decision for investment proposal No 79/QĐ-UBND on April 3rd,2020.

Trungnam Groupthen acceleratory completed legal procedure and fund as well as manpower for rapidly commencing the project through days and night working shifts in handing over the project in time.

Covering an area on 557.09ha including 17km power transmission line from Phuoc Minh commune in Thuan Nam district to Vinh Tan commune of Tuy Phong district of Ninh Thuan Province,Trungnam Group had fixed the construction schedule from May of 2020 to the fourth quarter of 2020.

With a target of completing the project in 102 days,Trungnam Group had finished land clearance process in 45 days with the hard working days from 8,000 labourers and engineers in handing over the project as proposed time of completion.

On the occasion of inauguration of the project,Chairman of Trungnam Group,Mr. Nguyen Tam Thanh was honourly awarded the Labour Order,Second Class from the State for completing the solar power plant and power transmission project,contributing to the development of renewable energy project in Ninh Thuan Province in particular,and to the course of the country's social republic and defence.

Trungnam Group also greatly contributed to help local community as a role and responsibility of a potential investor in Ninh Thuan Province. The Group,in co-operation with the provincial Fatherland Front,Thuan Nam communal people's committee and provincial association of poor patients,had donated 102 houses worth 5.1 billion Vietnamese dong to poor households in the province during construction of projects here.
