Nam Sak Dam Hydropower project is near Ban Hine Toc south of Muang Moc (Mok) in Thathom District of Xieng Khouang Province close to coordinates 19°04'59.9"N 103°37'59.9"E (19.0833, 103.6333). These coordinates are very general and not precise. The Nam Sak project seems not far from the Nam San 3A hydropower project.

The project is developed by Phongsubthavy Group and the output is planned to be exported to Vietnam when the project is finished.

Signing of the contract agreement for the electro-mechanical works of Nam Sak hydroelectric project in Lao PDR with Phongsubthavy Group was in September 2021.

The project consists of 3 turbine-generator units of 7.33 MW each for combined capacity of 22 MW - 11 kV voltage & 750 rpm speed. The contract includes design, engineering, supply, transportation of main inlet valves, turbines, generators, control system, 11 kV MV switchgear and plant auxiliaries, including supervision of installation and commissioning.
