The South-East Direct Current Passage planned by 50Hertz is one of the most important new transmission lines between northern and southern Germany that are needed for a successful energy transition. This high voltage direct current (HVDC) power link between Saxony-Anhalt and Bavaria, with its minimum length of 450 kilometres, should be operational in 2022.
The SuedOstLink was described in the 2012 grid development plan as "Corridor D" and laid down as project no. 5 (high voltage line Lauchstädt-Meitingen) in the federal requirement plan by the German Federal Parliament in May 2013. As such, it has been codified by Germany's Federal Government and Federal Parliament as a necessary element of its energy policy. It will be constructed as an overhead line with a voltage of 500 kV direct current between both grid connection points, i.e. the Lauchstädt substation near Halle (Saxony-Anhalt) and the Meitingen substation near Augsburg (Bavaria). It is necessary to cover the need for electricity transport in southern, northern and central Germany. Its significance is even greater, as the powerful nuclear power plants in central and southern Germany will be disconnected from the grid as of 2022.
The SuedOstLink is a joint project of 50Hertz and Amprion: 50Hertz is the contact for the federated states of Saxony, Saxony-Anhalt and Thuringia, while Amprion is responsible for Bavaria. For the realisation of this project, 50Hertz and Amprion have created a joint project team.
