Underground cable In operation: underground cable connecting offshore wind-farms in the Baltic Sea

SuedOstLink

The SuedOstLink connection planned by 50Hertz is one of the most important new transmission lines between northern and southern Germany and is important for a successful energy transition. This high-voltage direct current (HVDC) power link between Saxony-Anhalt and Bavaria will be able to transmit up to 2,000 megawatts of electricity and will have an approximated length of about 580 kilometers. The SuedOstLink is planned to be in operation by 2025.

The Federal Requirements Plan Act from the end of 2015 defines Wolmirstedt near Magdeburg (federal state of Saxony-Anhalt) and Isar near Landshut (federal state of Bavaria) as grid connection points. The connection will primarily be constructed by underground cabling, sections with overhead lines are subject to specific exceptions.

The necessity for the SuedOstLink was first described in 2012 in the Grid Development Plan as "Corridor D" and laid down as project no. 5 in the Federal Requirements Plan Act in May 2013. As such, it has been codified by Germany's Federal Government and the Federal Parliament as a necessary element of its energy policy. The SuedOstLink is important to cover the need for electricity transport in southern as well as northern Germany. In the north of Germany electricity from wind-turbines is produced in large amounts while powerful nuclear power plants in southern Germany will phase out during the coming years.

Responsible authority for the planning and approval process is the Federal Network Agency (Bundesnetzagentur). Currently, the project is in the planning phase (Bundesfachplanung), which is to define an up to 1,000 metre wide route corridor connecting Wolmirstedt with Isar. In this phase the Federal Network Agency will also specify if partial sections will be realised as overhead lines. In the following application process (Planfeststellungsverfahren) among other things an exact route for the connection will be found.

The SuedOstLink is a joint project of 50Hertz and TenneT: 50Hertz is responsible for planning in the federal states of Saxony, Saxony-Anhalt and Thuringia, while TenneT developes the Bavarian part. For the realisation of this project, 50Hertz and TenneT work closely together.
