As in many industrialised countries, nuclear power in Germany was first developed in the late 1950s. Only a few experimental reactors went online before 1960, and an experimental nuclear power station in Kahl am Main opened in 1960. All of the German nuclear power plants that opened between 1960 and 1970 had – like otherways in the whole world – a power output of less than 1,000 MW and have now all closed down. The first almost fully commercial nuclear power plant started operating in 1969: Obrigheim operated until 2005, where it was shutdown by phaseout decision of the government. The first station with a power output of more than 1000 MW each were the two units of Biblis Nuclear Power Plant in 1974 and 1976.
