Germany’s energy regulator Bundesnetzagentur has received applications from the country’s transmission system operators (TSOs) Tennet and 50Hertz for two high voltage direct current (HVDC) line projects, namely SuedLink and SuedOstLink.
The proposed SuedLink is being built to facilitate the transmission of power from offshore wind farms in the north to consumption centres in the south.
It entails the construction of around 600 km of HVDC lines with a capacity of 4 GW. The HVDC connection comprises two line segments. The first will run from Wilster in Schleswig-Holstein to Grafenrheinfeld in Bavaria, and the second will run from Brunsbüttel in Schleswig-Holstein to Großgartach (Leingarten) in Baden-Württemberg.
SuedLink will transport wind power from northern Germany to the industrial south, thereby playing a crucial role in Germany's energy transition programme Energiewende, which involves an energy shift following the country’s decision to fully abandon nuclear power by 2022 and boost renewable sources of power.
The roughly 580-km-long, ±500 kV HVDC SuedOstLink will run from Wolmirstedt in Saxony-Anhalt to Isar in Bavaria. The project is currently in the planning stage; the formal approval process is yet to start.
The HVDC corridor projects are being built to facilitate the transmission of power from offshore wind farms in the north to consumption centres in the south.
