Vattenfall has decided to invest in the 1,500 MW Hollandse Kust Zuid offshore wind farm that is said to be the largest offshore wind project, when commissioned in 2023. The wind farm will consist 140 turbines of 11 MW each.

Vattenfall was awarded permits for the construction of the wind farm after winning two subsidy-free tender rounds in 2018 and 2019. The two projects have been combined into one wind farm to optimise the process.

Post completion, the offshore wind farm will make a major contribution to the Dutch Government’s renewable energy targets. The electricity generation from the wind farm will be able to cover the annual consumption of over two million Dutch households.

Vattenfall has partnered with the following suppliers: Siemens Gamesa for turbine manufacturing and partial installation, Dutch based Sif Group for foundation manufacturing, Dutch based TKF for inter-array cable systems manufacturing, Prysmian for inter-array cable systems manufacturing, Subsea 7 for foundation and inter-array cable systems installation and Swire Blue Ocean for turbine installation.

The maritime space between turbines will be open to passage and co-use following government regulations. The operations and maintenance of the wind farm will take place from Vattenfall’s new service facility in the Port of IJmuiden. The wind farm will be connected to two offshore substations operated by Dutch TSO TenneT.
