History
The project was proposed in 1970s. Several studies were carried out, including by the Moscow Institute of Hydroelectric and Industry, Electricity and Power Distribution Company (Japan), Designing Research and Production Shareholding Company (Moscow) and SWECO (Sweden). In May 2000, the National Assembly of Vietnam postponed the decision due to lack of information on relocation and compensation plans and for feasibility studies for a scaled-down version of the dam. The project was approved by the National Assembly in December 2002. Construction of the dam began on 2 December 2005.On 17 December 2010, the first turbine was connected to the power grid. It was officially put into operation on 7 January 2011. The second turbine is planned to put to operation on 10 May 2011, and the third turbine on 20 October 2011.
