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.

Description

The dam is 138 metres (452.8 ft) high and 90 metres (295.3 ft) wide. Its length is over 1000 metres (3,280.8 ft).

The power plant will consist of six turbines with generating capacity of 400 MW each. It will have a total capacity of 2,400 MW with an expected annual generation of 10,246 GWh. The plant is expected to be fully operational by 2012. The total cost is US$2 billion. The plant is owned by Electricity of Vietnam. Turbines are installed by Lilama Joint Stock Co No 10.

Impact

The project required displacement of more than 91,000 ethnic minority people, the largest resettlement in Vietnam's history. Two pilot resettlement sites were established in 2003, and resettlement started in 2005.
