Don Sahong hydropower project, Laos

The real cost for 260 MW? Read about the story of the Don Sahong dam and support the demands of EJOs for more impact studies and ultimately the reconsideration of the whole energy plan.


Description
The proposed Don Sahong Hydropower Project is located on the Mekong River’s mainstream in the Si Phan Don area of southern Laos, less than two kilometers upstream of the Laos-Cambodia border. The project is one of 11 hydropower dams proposed or under construction along the Lower Mekong River. The dam would be between 30 and 32 meters high and generate 260 MW, mainly for export to Thailand or Cambodia. Being a land-locked, mountainous country, Laos has few options to diversify its energy sources. The Lao government believes that the hydroelectric energy program will be a source of income for fighting poverty, thereby achieving the so-called sustainable social and economic development of the country. The proposed Don Sahong hydropower project, therefore, is critical part of the Laos government’s hopes to transform the country into “the battery of Southeast Asia,” with revenues generated from exporting power to neighboring countries [6].

Project Details and Actors
Project DetailsThe power plant is proposed to have a nominal installed capacity of 260 MW, developed by discharging the design flow of 1600 m3/s operating at the rated head of 17.0m. Power output will vary with the seasonal flow variation, as in general terms a particular headwater/tailwater condition will correspond to a particular river flow, thus a particular power output.
Type of PopulationRural
Potential Affected Population>100,000

Impacts
Environmental ImpactsPotential: Food insecurity (crop damage), Loss of landscape/aesthetic degradation, Deforestation and loss of vegetation cover, Biodiversity loss (wildlife, agro-diversity), Desertification/Drought, Floods (river, coastal, mudflow), Global warming, Soil erosion, Surface water pollution / Decreasing water (physico-chemical, biological) quality, Groundwater pollution or depletion, Large-scale disturbance of hydro and geological systems, Reduced ecological / hydrological connectivity, Other Environmental impacts
OtherThe area is recognized by scientists as a critical year-round bottleneck for fish migrating throughout the lower Mekong basin, which local villagers capitalize on to harvest an abundant fish catch. The most significant environmental and socioeconomic impacts of the Don Sahong Dam would be felt by local and regional inland fisheries
Health ImpactsPotential: Malnutrition
Socio-economic ImpactsPotential: Displacement, Loss of livelihood, Loss of traditional knowledge/practices/cultures, Land dispossession, Loss of landscape/sense of place
Outcome
Project StatusPlanned (decision to go ahead eg EIA undertaken, etc)
Pathways for conflict outcome / responseUnder negotiation
Development of AlternativesAt first stage, International Rivers, WWF and others are demanding additional impact studies.

Secondly, their final suggestion is to cancel the project and register the area under the RAMSAR convention and encourage small scale tourism and conservation measures.

Sources and Materials
Legislations

Cambodia, Laos, Thailand and Vietnam are all bound by the 1995 Mekong Agreement. Therefore, the obligation to prevent harmful effects (the no-harm principle) as stipulated in Article 7 needs to be strictly respected. This principle is broadly recognized as a general principle of international law. Prior to that, it was reflected in the judgment of the International Courts of Justice (ICJ) in the Corfu Channel case in 1949, which reads: “every State’s obligation not to allow knowingly its territory to be used for acts contrary to the rights of other States.”
