Dong completes Borkum Riffgrund substation

GERMANY: Dong has completed the installation of the offshore substation for the 320MW Borkum Riffgrund 1 offshore wind farm, marking the first milestone in the North Sea project's installation.

The substation is lowered into position

The construction of the substation makes it possible to transport the electricity 55 kiometres from the 77 wind turbines, which have not yet been installed, to the converter station onshore.

The installation started on 1 August when the substation was shipped from the Aalborg in Denmark, from where the components were loaded on a floating pontoon and sailed to the construction site.

The next phase of construction is the installation of the turbine foundations, which is scheduled to start at the beginning of 2014. Commissioning of the complete wind farm is set for 2015.
