ABB Power Grids has been contracted by Aibel/Keppel FELS consortium to provide high voltage direct current (HVDC) technology for the DolWin5 offshore wind connection project.
As part of the DolWin5 project, TenneT Offshore has awarded a contract to Aibel and Keppel O&M, a unit of Keppel Corp, to design, engineer, procure, construct, install and commission a 900MW offshore HVDC converter station along with an onshore converter station.
Scheduled for completion in 2024, the project will deliver electricity from three wind farms, which are located about 100km off the German coast. The power delivered will be sufficient to power around one million homes.
The order awarded to ABB covers the converter platform in the North Sea, an onshore converter station in Emden, Lower Saxony, Germany. TenneT will provide power links to the offshore wind farms in this cluster.
ABB Power Grids business president Claudio Facchin said: “Our innovative HVDC technology, worldwide expertise, deep understanding of the renewables integration challenges, our partnership approach and close collaboration with TenneT, were key differentiators in winning this project.”
According to ABB, its HVDC solution will convert the alternate current (AC) to direct current (DC) on the converter platform, thus helping in transmitting the power generated by the offshore wind farms through a 130km-long DC cable system.
The DC power will be converted back to AC at the onshore converter station, and then integrated into the transmission grid.
