Xekaman Xanxay Dam Hydropower Info - Xekaman Sanxay - by Hobo Maps - Go to Hydropower Projects Page - - - Home

The Xekaman Xanxay (Sanxay) hydropower project is constructed on the Xekaman (river) about 40 km from the border with Vietnam in southeastern Lao PDR. The project is about 5 km downriver from the larger Xekaman 1 HPP.

The project generates 32 MW while acting as a downstream regulator for Xekaman 1 discharge. The 5 km of river between the two projects would likely have dramatic fluctuations in flow that match the discharged flows from Xekaman 1.

The Xekaman Xanxay project is a part of the 290 MW Xekaman 1 hydropower project acting as a downstream regulator to avoid flooding and stabilize downstream water flows.

Xekaman 1 and Xekaman Xanxay were both investments of Viet-Lao Power Joint Stock Company. Main contractor for the project is Vietnam-based Song Da Corporation.

Unconfirmed reports are that funding for the project was provided by the Vietnam government’s “Development Assistance Fund” and by Vietnamese commercial banks.

The Project catchment area is 3,740 square kilometers. The reservoir full supply level surface is 123 meters above mean sea level with low supply level at 122 meters above mean sea level. Active storage volume is 7.1 million cubic meters.

The plant has an installed capacity of 32 MW and average annual output capacity of 130 GWh.

Andritz Hydro provided complete electro-mechanical equipment for the project.
