Germany’s Federal Maritime and Hydrographic Agency (BSH) has approved the offshore grid connection system for BorWin5 and BorWin epsilon in the German North Sea.
The project involves the development of HVDC offshore wind transmission system connected to EnBW He Dreiht offshore wind farm in the North Sea, to the Garrel/Ost converter station near Cloppenburg in Lower Saxony, Germany. It will consist of a 230 km long connection (110 km of land cable, 120 kilometers of submarine cable ) using high-voltage direct current (HVDC) transmission technology with a maximum transmission capacity of 900 MW.
The offshore wind farm supplies 66kV three-phase current directly to the converter platform via submarine cables without its own transformer platform. In order to reach the federal government's expansion goal of at least 70GW of offshore wind energy by 2045, the area development plan is presently being modified.
