Project Details for Borkum Riffgrund I
General Information Name Borkum Riffgrund I correct
Other names correct
Country name Germany correct
Region Exclusive Economic Zone (DolWin) (BSH Cluster 2 in Draft Network Plan) correct
Comments A new foundation, Suction Bucket Jacket, will be tested at the site. DONG have teamed up with the UK Carbon Trust in order to test the new foundation. On 14th March, DONG announced an upgrade in the turbine capacity to 4MW - the rotor diameter remains unchanged. An additional 78th turbine will also be installed testing the new suction bucket foundation.

According to the April 2014 draft of the Offshore Network Development Plan, when Borkum Riffgrund I connects to DolWin3 the project will have a transmission capacity of 291MW available, despite the capacity of the wind farm being 312MW.
