The Houay KaOuane hydropower project is sometimes also spelled as Huay KaOuane, Houay Kaouane or Houay Ka-Ouane.

The project is being developed by Lao-based Phongsubthavy Group.

Houay KaOuane site location shown below in Attapeu Province of Lao PDR at coordinates - 14°41'38.1"N 107°19'05.1"E (14.693928, 107.318092).

The project location is near Som Boun Village, Phuvong District, Attapeu Province, Lao PDR - about 30 km by direct line from Attapeu Airport.

The project construction site is next to Houay KaOuane Waterfall as seen in this video. The project has a 111 meter head next to the waterfall.

Houay KaOuane stream flows north from the hydropower site about 7 km before joining the Xe Xou river as it flows west towards Attapeu town.

The project was planned to have 22.5 MW installed capacity from three 7.5 MW generators provided by Andritz but another report by Gamesa Electric indicates they will be providing three synchronous hydro generators for the project rated at 8 MW each which would make it a 24 MW facility. We estimate an annual output capability of about 100 GWh.

An unconfirmed report indicates the ownership entity is or will be Houay Ka-ouane Hydro Power Company.

The project is under construction in year 2024 as seen in the images below.

A Sept. 2023 report indicates that Electricity Vietnam has a desire to import power output from Houay KaOuane but a purchase agreement had yet to be signed at that time. The transmission route might join with the export of power from the Nam Kong 1,2&3 projects to Pleiku Vietnam as seen in Export Transmission map below.
