TenneT Seeks Grid Connection Systems Provider

TenneT has issued a call for tenders for the turnkey construction of two AC grid connection systems to connect the 342MW Kaskasi II and the 242MW Gode Wind 3 wind farms in the German North Sea to the associated HVDC sea stations.

The scope comprises all works, from design, to manufacturing, delivery, and installation, up to operational commissioning of a secure and high availability transmission of electrical energy from the grid connection points at the HVDC offshore station to the AC grid connection points on the offshore wind farm station.
