Nam Xay (Xai) Dam Hydropower Info by Hobo Maps - Go to Hydropower Projects Page - - Home

Nam Xay (Xai) Hydropower project is located in Mok District, Xieng Khouang Province of northern Lao PDR.

The project is developed by Phongsupthavy Group in year 2026 with intent to sell and export the output to Vietnam when the project is completed.

One report has the project capacity as about 9 MW but that needs confirmation.

Nam Xay (Xai) Hydropower project is probably located somewhere on the Mok District map below but we aren't sure exactly where.

Various news reports in June 2021 reported that Electricity of Vietnam (EVN) has exchanged power purchase contracts with Phongsupthavy Group for the Nam Yeuang hydropower plant cluster, the Nam Mo 2 project, Nam Tai, Nam Sak, Nam Sao and Nam Chao hydroelectric plants. Since Nam Xat HPP is probably located close to these plants, it might be easy to add output from Nam Xay to this 220 kV export transmission line that takes power to Vietnam's Tuong Duong substation.

Sorry but that's all we know about this project as of October 2026.
