Vattenfall has signed contracts with Prysmian Powerlink and Twentsche Kabelfabriek for the inter-array cable systems that will connect turbines of the Hollandse Kust Zuid windfarm to two offshore high voltage stations.
The Hollandse Kust Zuid windfarm will consist of four sites. Vattenfall was awarded permits to develop the sites after winning two separate tender rounds in 2018 and 2019.
The Netherlands-based TKF will supply the inter-array cables for Hollandse Kust Zuid 1 & 2. Prysmian, headquartered in Italy, will supply the cables for Hollandse Kust Zuid 3 & 4.
The contracted scope for TKF includes manufacturing and delivery of about 150 km of 66 kV aluminium core inter-array cables and accessories. Manufacturing of the cables will take place in Lochem and Haaksbergen, the Netherlands. Delivery of the cables is expected in 2022.
For Hollandse Kust Zuid 3 & 4, Prysmian will manufacture and supply about 172 km of 66 kV XLPE-insulated inter-array cables and accessories. Manufacturing will take place in Nordenham, Germany. Delivery is expected in 2022.
The Hollandse Kust Zuid windfarm is being developed by Vattenfall as the first subsidy-free offshore windfarm in the Netherlands. It will be fully commissioned in 2023 and will have an installed capacity of approximately 1.5 GW.
