Dutch-German grid operator TenneT has completed commissioning of the 900-megawatt DolWin5 offshore grid connection, enabling transmission of power from the Borkum Riffgrund 3 wind farm to the onshore station in Emden, the company said on Tuesday.
The system comprises a 130-kilometre high-voltage direct current (HVDC) cable and the DolWin epsilon offshore converter platform. TenneT said the infrastructure is now fully energised and ready for power transmission, with connection and testing activities at the wind farm proceeding in parallel.
Commissioning began in autumn as scheduled, following the summer installation campaign led by general contractor ANS—a consortium of Aibel and Seatrium—with Hitachi Energy and Prysmian also contributing to the project.
“All ancillary systems were put into operation on schedule, paving the way for the converter and high-voltage components to undergo dynamic testing,” TenneT said in a statement.
DolWin5 is part of Germany’s broader effort to expand offshore wind capacity and integrate renewable energy into its national grid. Once fully operational, Borkum Riffgrund 3 will feed electricity through the connection to help meet the country’s clean energy targets.
TenneT acknowledged the role of its partners in delivering the project: “We thank all involved partners and project teams for their commitment and expertise in achieving this important milestone.”
Financial details of the project were not disclosed.
