ABB books order for HVDC technology for offshore windDavid Wagman | May 10, 2019
ABB said that its Power Grids business received an order for its technology from the Aibel/Keppel FELS consortium, which will design, construct, and build a high-voltage direct current (HVDC) transmission system for the offshore wind connection project DolWin5.
The order is worth at least $112 million, ABB said.
The transmission project will deliver 900 megawatts of energy from three wind farms some 100 km off the German coast. It is scheduled to be completed in 2024.
ABB's 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, an electricity transmission system operator, will provide power links to the offshore wind farms in this cluster.
ABB’s HVDC technology converts alternating current (AC) to direct current (DC) on a converter platform. The process makes it possible to transmit power through a DC cable system with low losses to the mainland. In the onshore converter station, the power is converted back to AC and integrated into the transmission grid.
The order will also include the ABB Ability Modular Advanced Control for HVDC, which will control the connection between the offshore wind farms and the on-shore AC grid.
Germany plans to generate 65% of its power from renewable sources by 2030. Over the past decade its offshore wind production has grown from zero to 6,382 megawatts, making it the world’s second largest offshore wind producer after the U.K.
