Energizing power unit No. 3 of Trung Son Hydropower Project

At 18h05 pm on April 29, 2017, the power unit No. 3 of Trung Son Hydropower Project located in Trung Son commune, Quan Hoa district, Thanh Hoa province has been officially energized and successfully synchronized into  the national power grid. As such, the power unit No. 3 of Trung Son Hydropower Plant has been put into operation only more than one month after the energizing of power unit No. 2.

Trung Son Hydropower Project has been assigned by Vietnam Electricity to Trung Son Hydropower One Member Limited Liability Company under Power Generation Corporation No. 2 (EVNGENCO2) to be the Project owner. The Project is composed of four power units with the total installed capacity of 260 MW. This is the first hydropower project in Vietnam being financed by the World Bank.

After being put into operation, the power plant will contribute to the national power system an annual electricity generation output of 1.018 billion kWh, at the same time the plant will help control floods and irrigation in the downstream area of Ma river. Especially the project will create a new driving force for economic development, hunger eradication and poverty alleviation in Quan Hoa district (Thanh Hoa province).  

One of the objectives of Trung Son Hydropower Project is to mitigate and minimize social and environmental impacts caused by all construction and operation activities of the project. In particular the lives of project affected people will be improved remarkably after the project finishes. The project will bring about environmental benefits, for example greenhouse gas emission (GHGs) will be much lower than that of a fossil fueled power plant.
