HeideHub to Deliver 4 GW of North Sea Wind Power Across Germany
Germany’s northernmost power hub, HeideHub, is set to become a landmark in the country’s energy transition, linking offshore wind power from the North Sea to regional and southern grids. The project is a collaboration between transmission system operators TenneT Germany, Amprion, 50Hertz, and distribution operator SH Netz.
Located near the Heide/West substation in Lieth and Wöhrden, HeideHub is planned to connect two offshore wind grid links—LanWin2 (TenneT) and LanWin3 (50Hertz)—together delivering up to 4 GW of renewable electricity onshore. From there, much of the power will flow through the NordOstLink HVDC line toward Mecklenburg–Western Pomerania and the SuedOstLink+ corridor, supplying southern Germany. A converter for the Corridor B HVDC line, transporting electricity to North Rhine–Westphalia, will also be installed on site.
The hub integrates DC switchgear, converters, and substations, connecting planned infrastructure such as the 380 kV Hochwöhrden–Pöschendorf transmission line. It is designed not only for households but also for energy-intensive industry and potentially for green hydrogen production. The operators describe the facility as a “green power socket,” reflecting its central role in future energy distribution.
Preparatory work is underway: TenneT Germany recently conducted soil investigations at roughly 100 locations between Büsum and Heide to assess ground stability and conductivity for the onshore cables. Permitting is scheduled to begin in spring 2026, with construction expected to start in 2028.
