Xekong 3 Dams Hydropower Info by Hobo Maps - Go to Hydropower Projects Page - - - Home

Xekong 3A and 3B Hydropower projects on this web page are being developed by Lao-based Asia Investment and Development Co. Ltd. The dams are proposed to be located on the Xekong (Sekong) river in Xekong Province of southern Lao PDR.

Both 3A & 3B projects are apparently under construction in 2026.

Unconfirmed site location coordinates for Xekong 3A are - 15°23'04.2"N 106°46'44.0"E (15.384500, 106.778889) as shown as red marker on satellite image below just above Sekong town. Xekong 3A is designed to block the flow of the entire Xekong river, which has an average flow of 275 cubic meters per second at Sekong Town just south of the dam site.

Xekong 3B is another in the cascade of planned dams on the Xekong river, this one located 35- 40 km downstream of Xekong 3A near the village of Nonghin. Unconfirmed site location coordinates for Xekong 3B are - 15°07'11.5"N 106°49'23.8"E (15.119861, 106.823278) shown as red marker on satellite image below south of Sekong town.

The power output is expected to be transmitted, exported and sold to Electricity of Vietnam (EVN).

The developers entered into a Project Development Agreement with the Lao government on 30 May 2018.

As far as we know, a long-term concession contract with the Lao government has not yet been signed.

Xekong 3A is designed for 140 MW electrical output capacity while Xekong 3B is to be 146.7 MW capacity.
