The Kárahnjúkar Hydropower Plant in Iceland is a massive hydroelectric project designed to power aluminum smelter in the area. The plant is the largest in Iceland and generates 4,600 GWh annually. Completed in 2009, the project faced criticism for its environmental impact and heavy use of foreign workers. Despite controversies, it plays a significant role in providing electricity for the aluminum industry in eastern Iceland and there're also some interesting views from there.
