The Vemork hydroelectric plant is located in Norway and was completed in 1911. It was one of the first large-scale hydroelectric power stations in the world, harnessing the energy of the Numedalslågen River. The plant played a significant role in providing electricity to the region and supporting industrial development. During World War II, the Vemork plant became famous for its production of heavy water, which was crucial for the German nuclear weapons program. This led to several Allied sabotage missions aimed at disrupting the plant's operations. Today, Vemork is a museum that highlights its historical significance and contributions to energy production.
