This very conflictive hydroelectric dam is part of a complex of dams, it has an installed power of 690 MW and is meant to produce yearly 4.600 Gwh. It is placed to the north of the glacier Vatnajökull on the rivers Jökulsá á Brú and Jökulsá í Fljótsdal. Its purpose was to feed electricity to Alcoa's aluminium smelter Fjardaál, at Reyðarfjörður. The conflict was because of the project itself (finished in 2009) and also because it was seen as part of a much wider push for enormous investments in hyroelectricity at very high environmental cost for the benefits of aluminium multinationals such as Alcoa. The project was built by Impregilo, the Italian building firm. Opponents point out that the sediment from glacier water will fill the dam quickly.
