Lower Se San 2 Dam (also: Lower Sesan 2 Dam and Han Se San 2 Dam) is a proposed hydroelectric dam on the Se San River in Stung Treng Province, northeastern Cambodia. The Se San River is a major Cambodian tributary of the Mekong, conjoining in Stung Treng Province where the provincial capital of the same name is located. 25 kilometres (16 mi) east of this important conjunction on the Se San River, a hydropower dam has been proposed for development.

History[edit]

In 2007, a memorandum of understanding between Cambodia's Ministry of Industry, Mines and Energy and Electricity of Vietnam was signed, including the undertaking of an environmental impact assessment and a feasibility study for the Lower Sesan 2 project. In January 2011, Vietnam Ministry of Planning and Investment licensed Electricity of Vietnam to make a US$816 million investment into the project.[1] The government approved the project on 4 November 2012.[2] On 26 November 2012, the agreement on the dam construction was signed between the Royal Group and China's Hydrolancang International Energy.[3] Electricity of Vietnam announced that it has withdrawn from the project.[4]

Description[edit]

The project is carried out by the Hydro Power Lower Sesan 2 Co. Ltd., a joint company of the Royal Group of Cambodia and China's Hydrolancang International Energy. Electricity of Vietnam holds10% nominal stake in the project, Construction to be start in 2014 and the power plant should be completed by 2019. After 40 years of operation its ownership will be transferred to the government.[3] When completed, the power plant will have a capacity of 400 MW with an average output of 1,998 GWh per year.[1] It will have five turbines 80 each.[5] The dam is expected to cost US$781 million.[3]

Impact[edit]

According to the environmental impact assessment, the dam's reservoir is expected to inundate numerous villages upstream from the dam, which will result in the relocation of many thousands of villagers, many of whom have lived on or near the banks of the Se San River for generations. Both upstream and downstream, the effects of the dam are expected to drastically reduce the fishery resources of which many thousands more villagers depend on for food and income. The effects will likely be felt as far away as the Tonlé Sap Lake.

Both rivers Sesan and Srepok originate in Vietnam's central highlands then flow through Stung Treng and Ratanakiri (and Mondulkiri) provinces in northeast Cambodia, which makes hydropower development along these two Mekong tributaries an international and transboundary concern.

Impact: Up to 2,000 people will be displaced. At least 38,675 people, including a large number of indigenous peoples, included in at least 86 villages located along the Sesan and Srepok Rivers and in the reservoir area would lose access to the vast majority of their fisheries resources due to the dam blocking fish migrations from the Mekong and Sekong Rivers up the Sesan and Srepok Rivers. In addition, at least 87 villages in Cambodia located along tributaries of these two rivers would also lose access to migratory fish. In total, at least 78,000 people living above the Sesan 2 dam site are expected to lose access to migratory fish[6]
