XEPIAN-XENAMNOY HYDROPOWER PROJECT
PROJECT BACKGROUND

1 Project Location.

The Xepian-Xenamnoy HydroPower Project is located in the 2 Provinces: Champasak and Attapeu on the southern of lao PDR. As part of this 410 MW, one river diversion and two dams shall be constructed across the following three rivers: Houay Makchane, Xe Pian- Xe namnoy. The scheme’s main dam and other major structures will be located in Champasak Province. while the proposed powerhouse, tailrace channel and high voltage transmission line located in Attapu Province In 1995, a feasibility study for this project was already carried out.

2. Project Rationale

the Project is expected to generate 1,879 Gwh per year. The Project will export 90% of the electric power it generates to Thailand under a Power Purchase Agreement between the Electricity Generating Authority of Thailand and the PNPC, while the remaining 10% will be sold to the local grid under a Power Purchase Agreement between the PNPC and the Electricite du Laos. The Project will operate and manage the Project during the 27-years Concession Period after the 5-years Construction Period and commencement of commercial operations by 2019. After the expiry of the Concession Period, the PNPC will transfer the Operations and Management of the Project to the Government of Laos.
