Trị An is a hydroelectric dam and lake on the Đồng Nai River in Vĩnh Cửu, Đồng Nai, Vietnam. The power plant has an installed electric capacity of 400 MW[1] and produces around 1.76 TWh of electricity per year. The plant is operated by Trị An Hydropower Company, a subsidiary of Vietnam Electricity.[2]
The dam was built in 1984–1986 with the assistance of the Soviet Union.[3] The power plant became operational in 1988. The dam forms a man-made reservoir lake known as Trị An Lake. La Ngà village on the La Ngà River was created as a result of population displacement.[4]
The dam appears on the 5000 Vietnamese đồng note released in 1993.
