As one of the four transmission grid operators in Germany, 50Hertz is responsible for high-voltage power transmission; control at this level is decisive for the stability of the grid and to ensure a secure electricity supply in Germany and Europe. We are part of a European grid association, working closely with colleagues throughout Europe. 50Hertz is part of a European company, working alongside Belgian grid operator Elia in the Elia Group. We work together closely in many key areas. Individual activities such as IT or purchasing are organised at the group level, which means that in these areas colleagues from Elia and 50Hertz work in a team from both Berlin and Brussels.
