According to the Decision, the solar power plant shall use technology of photovoltaic battery and center inverter with a capacity scale of 450MW.

For the power transmission infrastructure: Building Thuan Nam 500kV substation with a capacity scale of 3x900MVA. As planned, in 2020, two 900MVA transformers shall be built beforehand.

It is planned to build the dual-circuit 500kV power line from Thuan Nam 500kV substation to 4-circuit transition connection point of Van Phong – Vinh Tan 500kV power line with the length of 2 kilometers; build the dual-circuit 500kV power line from the connection point to Vinh Tan Thermopower 500kV substation with the length of 13.5 kilometers; expand two 500kV feeders at Vinh Tan 500kV substation; build 4-circuit 220kV power line to connect with 220kV busbar in Thuan Nam 500kV substation and transiting on two circuits of Vinh Tan – Thap Cham 220kV power line with the length of 2 kilometers.

The investment in power grid transmission constructions must abide by the regulations and standards on construction safety, ensure the quality and synchronization, ensure the connection to the national power system and release the capacity of recycling energy power plants in the region in accordance with the law.

The investor, after completing the project, shall hand over the transmission grid infrastructure to Vietnam Electricity Corporation/National Power Transmission Corporation for management, as well as shall not be allowed to get the refund of investment (or handing over the work free of charge) complying with the commitment stated in the document of the investor dated 20 March 2020.

Besides, the investor shall take the responsibility to compensate the expenses for EVN in case of failure to ensure the progress of building the transmission infrastructure as committed. These expenses are paid based on the power trading regulations with the investor of the Van Phong 1 Thermal Power Plant Project.

The power works invested by private sector currently account for about 28%. In the future, this rate can be higher if the Government make the suitable policies to facilitate private sector to get profit.

For the transmission power grid, the private sector absolutely could jointly makes construction investment, because the State only exclusively perform the operation of the transmission power grid. The potential of private sector is very strong in investment in term of time duration as they can take initiative on compensation negotiation – site clearance without being bound to like any state enterprise.

The management and observation of the State on operating the power transmission system will ensure the fairness and transparency for all stakes joining the power market. Investing and building the power transmission grid by the private sector is completely possible as the design of the power transmission infrastructure of Vietnam is now pretty good; domestic construction consulting and design units are capable to implement such items.

When private investors participating in power transmission projects, it is necessary to select those with sufficient capital, human resources and experiences to implement the projects on schedule and in good quality.
