The power plant, Karahnjúkavirkjun, is the largest hydroelectric dam in Iceland and is largely used to bring electricity to the Fjarðaál aluminium smelter. While the environmental impact of both of these features has been a storm of controversy, Karahnjúkar is still a popular site for the scale of both the dam and surrounding nature.
