Vattenfall announced today it has signed final contracts with cable specialists Prysmian Powerlink S.r.l. (Prysmian) and B.V. Twentsche Kabelfabriek (TKF) for the manufacturing and supply of the inter-array cable systems for its Hollandse Kust Zuid wind farm zone.

Hollandse Kust Zuid, located approximately 18 km off the coast between The Hague and Zandvoort, will consist of four sites. Vattenfall was awarded permits to develop these four sites after winning two separate tender rounds in 2018 and 2019. The selection of inter-array cable suppliers also took place through two tendering processes.

The grid connection for Hollandse Kust Zuid consists of two offshore transformer platforms, each with two 220 kV AC cables per platform. The inter array cable system will connect the approximately 140 Siemens Gamesa’s SG 10.0-193 DD wind turbines with these two platforms.

The contracted scope for Dutch cable specialist TKF includes the manufacturing and delivery of about 150km of 66 kV aluminium core inter-array cables and accessories to be installed in Hollandse Kust Zuid 1 & 2. Manufacturing of the cables will take place in Lochem and Haaksbergen, the Netherlands. Delivery of the cables is expected in 2022.

Prysmian, headquartered in Italy, is responsible for the manufacturing and supply of about 172 km of 66 kV XLPE-insulated inter-array cables and accessories for Hollandse Kust Zuid 3 & 4. Manufacturing will take place in Nordenham, Germany. Delivery is expected in 2022.

The Hollandse Kust Zuid wind farm is being developed by Vattenfall as the first subsidy-free wind farm in the Netherlands. It will be fully commissioned in 2023 and will have an installed capacity of approximately 1.5 GW.
