The German Federal Maritime and Hydrographic Agency (BSH) has given planning approval for DolWin4 – the first offshore grid connection system by German transmission system operator (TSO) Amprion Offshore. DolWin 4 will be operational in 2028 and will connect three offshore wind farms to the German grid.
Planning approval decision for DolWin4, Amprion has not yet received the final building permit but needs to go through a multi-stage approval process by the BHS. The main orders were placed last year, with Siemens Energy and Dragados Offshore selected to supply the converter platform and Prysmian to deliver the submarine cables. Amprion started onshore construction work for the DolWin4 and BorWin4 offshore grid connections at Norderney Island’s North Beach in July 2022.
The DolWin4 and BorWin4 projects combined will have a connection capacity of 1.8 GW. Additional offshore grid connections by Amprion are in the pipeline with BalWin1 and BalWin2, scheduled to go into operation in 2029 and 2030, respectively.
