International concerns about Lao’s plans to massively dam the Mekong River and its tributaries have again been brushed aside by the authorities in Vientiane who have announced new contracts worth about $1.0 billion to build three dams.
The dams will feed a hydropower plant on two tributaries of the Se Kong River, just 100 kilometers from Laos’ southern border with Cambodia. The Se Kong flows into the Mekong from the Bolaven Plateau which then feeds into the Lower Mekong Delta.
However, no environmental impact assessments are known to have been done and the incident has further stoked tensions between Laos and conservation groups and regional countries already angered with Vientiane and its attitude towards the construction of the U.S. $3.8 billion Xayaburi Dam to be built 150 kilometers downstream from the old royal capital city of Luang Prabang,
The Xe-Namnoy will be constructed by South Korean firm SK Engineering & Construction and will be aimed at producing 400 megawatts of electricity from water flowing from a height of 630 meters.
