Nam Emeun 1 & 2 Dams Hydropower Project by Hobo Maps - Go to Hydropower Projects Page - - - HOME

In 2023 a new hydropower project feasibility study was announced with the name Nam Emeun 1 & 2 which is a different project than the existing Nam Emoun hydropower project. Very confusing with similar names and both located in Sekong Province.

This web page below is for the new proposed Nam Emeun 1&2 project that has yet to begin construction in 2026. Click HERE to see our other web page for the existing Nam Emoun hydropower project.

Nam Emeun is sometimes also spelled Nam E-meng, Nam E-meun or Nam Emoun (same spelling as other existing project unfortunately).

A Project Development Agreement (PDA) feasibility study for the Nam Emeun 1 & 2 hydropower projects was signed by the Lao Ministry of Planning and Investment and Xaysana Energy Sole Co., Ltd. in Vientiane on 6 September 2023.

The concept includes a hydropower project with installed capacity of 75 MW, a pump storage facility of 100 MW and a floating solar power faciity of 50 MW. Total installed capacity would be 225 MW with most output planned for export to Cambodia.

The project is estimated to cost US$ 450 million. The main shareholders are Xaysana Energy Sole Co., Ltd. and Space Hydro Power Sole Co., Ltd.

This mixed clean-energy project combines power generated from both water and solar and may be the first of its kind in Laos. The pump storage recycling system would operate at night when energy demand is lower by pumping water to a higher level for later daytime peak-demand power generation.

6 September 2023 PDA signing ceremony below:

In December 2024 it was announced that PowerChina will be the engineering, procurement, and construction (EPC) contractor for the first phase of the project involving construction of a 90 MW hydropower plant.

The project output is to be included in the Laos-Cambodia power interconnection plan and primarily exported to Cambodia to help alleviate Cambodia's seasonal electricity supply shortages.

On 25 March 2024 in Vientiane a Memorandum of Understanding (MoU) was signed between Cambodia’s Ministry of Mines and Energy and Xaysana Group, WIS, and Sisan International Joint Development Sole Ltd. for the future offtake and purchase of electricity from Nam Emeun 1& 2 Hydropower, Wind Power and Pump Storage Hybrid Projects in Laos for export to Cambodia.
