Germany’s Ministry of Economy has announced the start of construction works on the 700 km Suedlink high-voltage direct current (HVDC) transmission line, which will link Brunsbüttel in Schleswig-Holstein (northern Germany) to Heilbronn (southern Germany).
The 525 kV underground line, which will have a capacity of 4 GW, is being built by the transmission system operators TenneT and TransnetBW, with an investment of approximately €10bn. TenneT is responsible for the northern section of the cable connection, while TransnetBW is responsible for the southern part. Completion of the project is expected for 2028.
In late July 2023, Germany had launched the construction of the first converter for the project, located in Leingarten (Baden-Württemberg).
