TenneT & TransnetBW select Hitachi for the SuedLink HVDC project (Germany)

5 Aug 2022

The German power transmission system operators TenneT and TransnetBW have selected Hitachi Energy to supply a transmission solution for the 2 GW SuedLink DC4 high-voltage direct current (HVDC) interconnection project that will run between the city of Wilster (Schleswig-Holstein) in the north of Germany and Bergrheinfeld (Bavaria) in the south of the country. The 2 GW project, which should be commissioned in 2029, will transmit electricity for 550 km underground, at ±525 kV, sending wind power from the north to the industrial south, or alternatively solar power from the south to the north when needed.

TenneT is responsible for the northern section of the route and the converters in Schleswig-Holstein and Bavaria. The southern section of the route and the converter in Baden-Württemberg fall within the area of ​​responsibility of TransnetBW. The entire project (700 km) consists of two high-voltage direct current (HVDC) transmission links with a total capacity of 4 GW,  with an investment of approximately €10bn.
