Vattenfall has made the final investment decision for the 1500MW Hollandse Kust Zuid 1-4 offshore wind farm off the Dutch coast.
Construction will start next year.
The wind farm will begin operations in 2023.
Vattenfall was awarded the rights to build Hollandse Kust Zuid after the company won two subsidy-free tenders in 2018 and 2019.
The two projects, Hollandse Kust Zuid 1&2 and 3&4, were combined into a single one to optimise the process, Vattenfall said.
Vattenfall chief executive Magnus Hall said: “The Hollandse Kust Zuid project underlines our commitment to generate fossil-free electricity for the Netherlands and Europe.
“In addition, the final decision for this investment shows that despite the corona crisis, we are sticking to our goal of enabling life without fossil fuels within a generation.”
In 2023, Hollandse Kust Zuid will account for a third of the total installed offshore wind capacity in the Netherlands, and will make a “significant contribution” to the Dutch government’s renewable energy and decarbonisation goals.
Vattenfall wind business head and senior vice president Gunnar Groebler said: “Hollandse Kust Zuid will not only supply our private and business customers with fossil-free and cheap electricity. It is also a large infrastructure investment that creates significant economic activity and employment in economically uncertain times.
“Thanks to good cooperation with our national and international partners, we are well prepared for the next steps towards realizing this milestone project.”
Siemens Gamesa is supplying the project’s 140 11MW turbines, while Sif Group is providing the monopile foundations.
Swire Blue Ocean will transport and install the turbines deploying its installation vessel Pacific Osprey.
TKF and Prysmian are supplying the inter-array cable systems for the project.
Subsea 7 has secured a contract for the installation of the project’s foundations and array cables.
Electricity production of the wind farm will supply up to two million Dutch households annually.
The sea space between the turbines will be open for passage and shared use in accordance with government regulations.
Operation and maintenance activity will be carried out from Vattenfall’s new service facility in the port of IJmuiden.
The wind farm will be connected to two 700MW offshore substations operated by Tennet, HKZ Alpha and HKZ Beta.
