50Hertz operates the electricity transmission system in the north and east of Germany, which it expands as needed for the energy transition. Our extra high voltage grid has an electrical circuit length of more than 10,000 kilometres, or the distance between Berlin and Rio de Janeiro. The 50Hertz control area covers the German federal states of Brandenburg, Mecklenburg-Western Pomerania, Saxony, Saxony-Anhalt and Thuringia, as well as the city states of Berlin and Hamburg. 

Within these regions, 50Hertz and its 1,600 employees ensure that 18 million people are supplied with electricity around the clock. 50Hertz is a forerunner in the field of secure integration of renewable energy: 

Until 2032 we want to integrate 100 percent of renewable energy securely. 

The shareholders of 50Hertz are the Belgian Elia Group (80 per cent) and the KfW bank group with 20 per cent. As a European transmission system operator, 50Hertz is a member of the European association ENTSO-E.
