Description

The Xayaburi Hydroelectric Power Project has been proposed on a site located 350 kilometers (220 mi) upstream of Vientiane and 770 kilometers (480 mi) downstream of Jinhong, the last dam of the Chinese cascade of seven dams, including four existing dams and three planned ones. In terms of mean energy supply, it would be the third largest project among those considered for development on the mainstream in the Lower Mekong Basin.

The Xayaburi HPP will be 820 metres (2,690 ft) long and 32.6 metres (107 ft) high with a rated hydraulic head of 18 metres (59 ft). Sitting at the head of a 272,000 sq kilometres (105,000 sq mi) catchment area, it would create a pondage area of 1.3 km3 (1,100,000 acre·ft) gross storage capacity and a surface area of 49 sq kilometres (19 sq mi). The pondage area will reach 30 metres (98 ft) in depth and stretch between 60 and 90 kilometres (37 and 56 mi). The barrage will feature a navigation lock, low level outlets for sediment flushing, a state-of-the-art fish passing facilities and two fish lifts.

The power plant will house seven 175 MW Kaplan turbine-generators and one 60 MW Kaplan turbine generator. The total installed capacity will be 1,285 megawatts, with a total annual energy production of 7,406 GWh. Around 95% of produced electricity (the seven 175 MW generators) will be exported to Thailand through a planned 200-kilometre (120 mi) long transmission line from the Xayaburi HPP to the Loei Province in Thailand. The barrage's construction would take eight years and it would cost approximately US$ 2.2 billion. It is expected to become operational by 28 October 2019.
