Nam Chiane 1 Hydropower Project is located at upper reaches of Nam Chiane River which is located at central Laos. The project area is located at the southern slope of Xieng Khouang Plateau, with terrain high in the north and low in the south. The elevation of the damsite zone is generally 900m~1300m, and changes to 500m~450m to the plant site in the south. Nam Chiane River is a tributary of Nam Ngiep River, flowing from the south to the north. The powerhouse is on the left bank of Nam Chiane River, being located at the contact zone where canyon is transiting to alluvial plain. The gross head of the hydropower project is about 600m. Headrace development is employed for the hydropower project, and the project area is located in Xieng Khouang Province.

The main task of the Project is power generation, and the power is consumed mainly in Xieng Khouang Province. The electric energy generated by Nam Chiane 1 Hydropower Project will be transmitted to the proposed Thavieng Substation, and then to the 230kV national power grid.

On August 2012, China Gezhouba (Group) Corporation (CGGC) submitted to Electricite du Laos (EDL) Feasibility Study Report of Nam Chiane 1 Hydropower Project in Laos (hereinafter referred as Feasibility Study Report) . After the report was approved by EDL and Lao Ministry of Energy and Mines, CGGC signed general contract (EPC) of Nam Chiane 1 Hydropower Project with Laos Government on December 2012.
