The 684 MW Sanakham Hydropower Project in Laos is a proposed run-of-the-river Mekong mainstream dam to be developed by a subsidiary of Datang International Power Generation Co. (81%)—which, in turn, is a subsidiary of China Datang Corporation, one of five state-owned large-scale power generation enterprises in China—and the Laos government (19%). It comprises 12 turbines or generators, each producing 57 MW. Located approximately 155 kilometres west of Vientiane, the Sanakham dam is just two kilometres north of Thailand’s border and between two delayed mainstream dam projects at Pak Lay and Pak Chom.
The Sanakham Hydropower Project is part of a push from Laos to use the Mekong river to become the ‘battery of Southeast Asia’, along with two operational Mekong mainstream dams at Xayaburi and Don Sahong, and seven more in various stages of planning. While financiers have yet to be named for the project, the bulk of the power will likely be sold to neighbouring countries rather than meeting growing power needs in Laos.
The Sanakham Hydropower Project was first proposed by the Laos government in September 2019. In May 2020, the MRC announced that the project would undergo the regional body’s Procedures for Notification, Prior Consultation, and Agreement (PNPCA), a voluntary project review process from MRC members, becoming the sixth Mekong mainstream dam to do so. Dams at Pak Beng and Pak Lay remain on long-term hold despite undergoing the PNPCA due to ongoing environmental concerns and failure to secure power purchase agreements from Thailand.
Since then, Thailand has repeatedly raised strong objections to the Sanakham dam. In November 2020, in a breach of diplomatic protocol, Somkiat Prajamwong, Secretary-General to the Office of National Water Resources of the Thai government, was quoted in the Bangkok Post saying that the Thai authorities had serious concerns about the impact of the project on the ecological system of the Mekong River, as well as the livelihoods of those living along its banks.
In January 2021, the Thai authorities raised concerns again at a meeting hosted by the MRC, saying it rejected a new technical report submitted by the Laotian government and Datang. On that occasion, Somkiat Prajamwong was again quoted in the media saying: ‘We are raising our concerns through the [MRC], which sent us the insufficient and out-of-date data … This will be the first dam that is being built so close to Thailand, we are worried about the impact, since it will be unpredictable.’
Since the Sanakham Hydropower Project was first announced, environmental organisations in Thailand have objected to it on grounds that the dam will further degrade distressed fisheries, harm biodiversity of the Mekong mainstream, and possible safety issues related to the Loei Fault.
In May 2020, it was alleged that Laos had already begun building roads to the building site of the dam prior to approval of the project from the MRC, an allegation that was denied by a representative from the Laos Department of Energy and Policy and Planning.
According to the Resettlement Action Plan for the Sanakham Dam drafted by Datang International Power Co., 1,127 residents of three villages in the area will have to be entirely resettled and 1,808 people in ten other villages will require relocation. According to the MRC, 27.7 million USD has been allocated by the project developers for environmental and social mitigation measures.
Though the Lao authorities see the Sanakham Hydropower Project as a boon for the economy, the power is largely to be bought by Thailand, a plan complicated by the fact that Thailand has seen a growing power surplus in the wake of the Covid-19 pandemic. In June 2020, a number of local environmental advocacy organisations reached out to the Thai government to demand that Thailand not buy power from the Sanakham dam in order to prevent its construction, a move mirrored by some Thai legislators.
Rak Chiang Khan Conservation Group, Save the Mekong, International Rivers, and other NGOs have issued statements and open letters against the building of the dam at Sanakham due to adverse effects on fisheries and the livelihoods of riparian communities who depend on the Mekong’s biodiversity.
In July 2020, the MRC Joint Committee rejected documents submitted for Prior Consultation, as they found that portions of the Sanakham’s Transboundary Environmental and Social Impact Assessment and Cumulative Impact Assessment were plagiarised from the dam project at Pak Lay.
Possible problems related to the Loei Fault are not discussed in the project information submitted for the PNPCA. However, following earthquake activity in 2019, Laos’s Department of Mineral Resources plans to assess and study the Loei Fault in 2022.
