Source-derived summary

Sơn La Dam is a concrete gravity dam on the Black River in Ít Ong, Mường La District, Sơn La Province, Vietnam. It is the largest hydroelectric power station in Southeast Asia.

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. 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 was put to operation on 10 May 2011, the third turbine on 20 October 2011, the fourth turbine on 22 December 2011, the fifth turbine on 30 April 2012, and the sixth turbine on 26 September 2012.

Editorial summary

This brief starts where responsible research should: with the source description of “Sơn La Dam” as dam in Mường La District, Sơn La Province. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA strong orientation record where physical form, institutional use and historical geography need to be read together. The current lead gives the account dated anchors—2000, 2002, 2005, 2010—that can be checked directly. The linked authority record independently contributes the date 2005. The account is most persuasive where Mường, District and Province can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the places & architecture register because the source frames it as dam in Mường La District, Sơn La Province. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Jul 1, 2026. The linked authority identifier is Q992482. VIAF identifies the subject as 172431882. The Library of Congress control number is n2011047609. Authority coordinates are 21.500, 104.012. 3 of 4 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2000, 2002, 2005 and 2010.

Critical limits

A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
