Hundreds missing in Laos after hydropower dam collapse
Bangkok, Jul 24 : Hundreds of people are missing and an unknown number believed dead after a partly-constructed hydropower dam in southeast Laos collapsed, sending flash floods surging through six villages, state media reported today.
Communist Laos is traversed by a vast network of rivers and there are several dams being built or are planned in the impoverished and landlocked country, which exports most of its hydropower energy to neighbouring countries like Thailand.
Laos News Agency said the accident happened at a hydropower dam in southeastern Attapeu province’s Sanamxay district late Monday, releasing five billion cubic metres of water — more than two million Olympic swimming pools — which unleashed flash flooding coursing into nearby villages.
The report added that there were “several human lives claimed, and several hundreds of people missing”.
Images published in the report showed scores of people, some clutching young children, crammed onto low-slung wooden boats and wading through muddy waters.
Several houses in the southern part of the district were swept away following the dam’s collapse around 8pm (1300 GMT) on Monday evening, the report said, as officials in the province put out a call for relief aid for flood victims.
“We do not have any formal information yet about any casualties or how many are missing,” an Attapeu official told AFP on condition of anonymity, adding that was “no phone signal” in the flooded region.
“We sent rescue teams who will help them and provide basic assistance first,” the official added.
The $1.2 billion dam is part of a project by Vientiane-based Xe Pian Xe Namnoy Power Company, or PNPC, a joint venture formed in 2012.
Among the companies involved in the project according to the Laos News Agency are Thailand’s Ratchaburi Electricity Generating Holding, South Korea’s Korea Western Power and the state-run Lao Holding State Enterprise.
The 410 megawatt capacity dam was supposed to start commercial operations by 2019, according to the venture’s website.
The project consists of a series of dams over the Houay Makchanh, the Xe-Namnoy and the Xe-Pian rivers in neighbouring Champasak Province.
It planned to export 90 percent of its electricity to energy hungry Thailand and the remaining amount was to be offered up on the local grid.
Under the terms of construction, PNPC said it would operate and manage the power project for 27-years after commercial operations began.
When contacted by phone in Laos’ capital Vientiane a company official told AFP: “We do not have any official reports about it yet. We are gathering information.”
Dam projects in Laos, mainly providing power to neighbouring countries, have long been controversial with fears over environmental damage and the impact on communities who are often displaced to make way for the construction.
A massive hydroelectric project at Xayaburi, led by Thai group CH Karnchang, is at the heart of Laos’ plan to become “the battery of Southeast Asia”.
The 1,285 megawatt dam — which will cost $3.5 billion according to state media — has sharply divided downstream Mekong nations like Vietnam and Cambodia who worry it will disrupt vital ecosystems and their own river systems.
Communist authorities in Laos keep tight control information and is often opaque about business deals and development projects.
The country has around 10 dams in operation, 10 to 20 under construction, and dozens more in planning stages.
