As part of its energy transition (“Energiewende”), Germany plans to generate 65 percent of its power from renewable sources by 2030. A rapidly growing proportion of this clean energy is generated in huge offshore wind farms in the North Sea. In just 10 years, Germany’s offshore wind production has grown from zero to 6,382 megawatts, making it the world’s second largest offshore wind producer after the UK.
Hitachi ABB Powergrids was awarded the Dolwin 5 project from the Aibel/Keppel FELS consortium which will design, construct, and build the High Voltage Direct Current (HVDC) transmission system for the offshore wind connection project DolWin5. Hitachi ABB Powergrids is the HVDC technology provider.
The award of this project underscores the strength of our technology and expertise in offshore wind and the confidence of the end customer (TenneT) in the Hitachi ABB Powergrids-Aibel-Keppel FELS collaboration.
Hitachi ABB Powergrids scope of supply includes design, engineering, procurement, construction and installation of the onshore converter station, as well as the installation of the offshore converter station and commissioning.
The order includes the converter platform in the North Sea, as well as an onshore converter station located in Emden, in the Lower Saxony region of Germany. TenneT, a leading European electricity transmission system operator, with activities in the Netherlands and in Germany, is responsible for providing power links to the offshore wind farms in this cluster.
This project will deliver 900 megawatts of zero-carbon electricity – enough to power around 1 million homes - from three wind farms some 100 km off the German coast. It is scheduled for completion in 2024.
