XePian Lower Dam Hydropower info by Hobo Maps- Go to Hydropower Projects Page - - Home

The Lower Xepian hydropower project is to be located near Ban HinLat (village), Sanamsai District, Sekong Province in southern Lao PDR. The project is about 40 km southwest of Attapeu town and about 80 km from Pakse District, Champasack province.

The project coordinates are 14°44'56.0"N 106°27'04.0"E (14.748889, 106.451111) as seen in the satellite images below.

A concept image of what the dam may look like is below.

Lower Xepian HPP is on the Xepian (river) according to the developer but Google Maps shows that river as Vang Ngao and Ban Hinlat is also on the Vang Ngao. We aren't sure which is correct. Maybe the XePian river is a tributary to the Vang Ngao?

Normal reservoir water level is 102 meters above sea level while dead water level is 101 meters.

Installed capacity : 14.8 MW from two Francis turbine-generator sets.

Annual average energy output estimate : 60 GWh

Total investment cost estimate : $ 34.6 million USD

Vientiane Automation and Solution Engineering (VASE) is involved with this project in the planning stages and in 2023 has info on their web page HERE.

Not sure who the developers and owners of the project are.
