History
The project was proposed in the 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.
