TenneT TSO GmbH has issued a tender notice for the design, manufacture, installation, and commissioning of the BorWin6 converter platforms.
Located in the North Sea Cluster 7, the 900 MW BorWin6 is scheduled to be commissioned by 2027.
The offshore grid connection will collect the three-phase electric power generated at an offshore wind farm to be selected in the 2022 auction round.
The electricity will then be converted into direct current at the BorWin kappa offshore converter platform and transported to an onshore converter station near Büttel via an export cable.
The tender covers the corresponding onshore and offshore converter stations, as well as the offshore platform.
The delivery and installation of the HVDC export cable, approximately 235 kilometres long, is the subject of a separate tender.
The tender remains open until 17 January 2021.
