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. |url = http://www.wrm.org.uy/bulletin/69/Vietnam.html |title = Vietnam starts resettlement to make way for massive Son La dam |first = Chris |last = Lang |publisher = World Rainforest Movement |date = April 2003 |access-date = 2011-01-22 |url-status = dead |archive-url = https://web.archive.org/web/20120316161705/http://www.wrm.org.uy/bulletin/69/Vietnam.html |archive-date = 2012-03-16 Construction of the dam began on 2 December 2005. | url = http://www.hydroworld.com/index/display/article-display/0133490777/articles/hrhrw/News-2/2010/07/2_400-mw-son_la_hydro.html | title = 2,400-MW Son La Hydro Project Starts Generating Power in Vietnam | work = HydroWorld | publisher = PennWell Corporation | date = 2010-12-21 | accessdate = 2011-01-22}} | url = http://english.vietnamnet.vn/fms/society/55280/son-la-hydro-power-plant-completed-three-years-ahead-of-schedule.html | title = Son La hydro-power plant completed three years ahead of schedule | work = VietnamNet Bridge | date = 2012-12-21 | accessdate = 2013-01-15}}
On 17 December 2010, the first turbine was connected to the power grid.

Description
The dam is an RCC Gravity Dam 138 m high and 90 m wide at the base. | url = http://www.soil.co.uk/content/son-la-dam-vietnam | title = Son La Dam, Vietnam | publisher = Soil Instruments Ltd | accessdate = 2011-01-22}} Its length is over 1000 m. | url = http://www.earthtimes.org/articles/news/255217,cracks-found-on-vietnams-son-la-dam.html | title = Cracks found on Vietnam's Son La dam | work = The Earth Times | date = 2009-02-11 | accessdate = 2011-01-22}} It was designed by Hydroproject of Russia.
The power plant consists of six turbines with generating capacity of 400 MW each. It has a total capacity of 2,400 MW with an expected annual generation of 10,246 GWh. The total cost of the project was US$2 billion. The plant is owned by Vietnam Electricity. 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. | url = http://www.internationalrivers.org/southeast-asia/vietnam/son-la-hydropower-projec | title = Son La Hydropower Project | work = International Rivers | accessdate = 2011-01-22}}
