The dam is built on the run-of-river model, which does not require water to be stored, local daily Vientiane Times on Monday quoted Mr.Somphith Keovichith, Lao director general of the Department of Energy Business under the Ministry of Energy and Mines as saying.
Water inflow equals water outflow, which is the concept behind a run-of – river dam. Due to unseasonably low rainfall, the level of the lower Mekong and other rivers in Laos has fallen significantly, and rice farmers have been suffering the effects, Somphith said.
The low level of the Mekong has been attributed to unusually low rainfall in Luang Prabang province, some 220 km north of the capital Vientiane, Xayaboury province, some 300 km north of capital Vientiane, and in areas of the Xayaboury dam, some 350 km upstream of Vientiane capital.
From January to July of 2019, the amount of rain recorded was the lowest in the last 10 years, said Somphith.
According to the “Bangkok Post” report, CK Power denied that the water
throughput has changed and that water shortage is the cause of the low
water level in the river.
The Xayaboury Hydropower Project will be one of the largest river
hydropower stations on the Mekong River. The dam was built in 2012 with
an installed capacity of 1,285 MW and is expected to generate 7,370 GWh
of electricity per year. Most of the electricity generated will be sold to
The government expects to earn 3.9 billion U.S. dollars from the operation of the dam throughout the 29-year concession period, including 1.897 billion U.S. dollars in royalties and 637 million U.S. dollars in taxes.
