The aluminum plant in Sunndalsøra, operated by Hydro, is the largest and most modern primary aluminum smelter in Europe. Situated at the head of the Sunndalsfjord in Møre og Romsdal county, the facility utilizes the abundant clean hydropower from the surrounding mountains for its energy-intensive electrolysis process. The plant underwent massive expansion after World War II and today serves as the economic backbone of the entire Sunndal municipality. Hydro Sunndal produces approximately 450,000 tonnes of primary aluminum annually, which is in high demand globally across sectors such as automotive, construction, and packaging. In recent years, hundreds of millions of kroner have been invested in cutting-edge technologies to enhance energy efficiency and reduce carbon emissions. The plant is also a vital site for research into new aluminum alloys. This industrial presence is harmoniously embedded within the spectacular fjord landscape, making Sunndalsøra a prime example of modern Norwegian industrial culture.
