Project Name Conduct of River Cross Section Survey and Dam Break Analysis for the Xe-Pian Xe-Namnoy Hydroelectric Power Project
Project Narrative
Xe-Pian Xe-Namnoy Power Company limited (“PNPC”), comprising of SK ecoplant Co., Ltd. (SKeP), Korea Western Power Co., Ltd. (KOWEPO), Ratch Group Public Company Limited (RATCH), and Lao Holding State Enterprise (LHSE), is a Company established under the laws of Lao PDR and is the owner of the Xe-Pian Xe-Namnoy Hydroelectric Power Project (the Project).
The Project is located in the Southern Lao PDR in Champasack and Attapeu Provinces on the Bolaven Plateau. The dams and appurtenant facilities, reservoirs, upper waterway and vertical shaft are located in the eastern part of the Bolaven Plateau. The lower waterway and powerhouse are located about 5 km to the North-West of Attapeu Province. The Project consists of a diversion weir and two dams on the Bolaven Plateau, Champasack Province. The impounded reservoirs are interconnected via water conduits with water being diverted from the Houay Makchan and Xe-Pian rivers and stored in the Xe-Namnoy Reservoir. From there, water is transferred via 17km of
headrace and high pressure tunnels to a powerhouse located at the base of the Bolaven Plateau escarpment where the 630m of head is used to generate electricity. The water is discharged into the Sekong River, a tributary of the Mekong, downstream of the powerhouse via a tailrace channel. The plant generation is 410 MW.
