Onshore Site Preparation

50Hertz reports on its BEI interconnector project page (last updated January 2026) that installation of the underground cable conduit system for the German land route has already begun. This conduit runs approximately nine kilometres from the port of Vierow on the Greifswald Bodden northward to the planned new transformer and converter station site at Rappenhagen in Mecklenburg-Western Pomerania. Critically, this cable conduit is shared infrastructure: 50Hertz states that the installation has begun "in connection with the construction work for the Ostwind 3 offshore grid connection system", meaning the conduit serves both the Ostwind 3 project and the future BEI Bornholm-Germany HVDC land cable. The BEI cable will be fed into this pre-installed conduit at a later date once BEI-specific construction begins. This is preparatory shared infrastructure rather than the formal start of BEI project construction — FID for BEI has not yet been reached (projected 2027) and BEI-specific onshore works (converter station construction, cable pulling) have not commenced. The conduit work is nevertheless a material physical milestone for BEI as it secures the German onshore cable route corridor and reduces future construction risk and duration for the BEI interconnector.
