Hollandse Kust Zuid offshore wind farm

Offshore windfarm Hollandse Kust Zuid inaugurated: Vattenfall, BASF and Allianz showcase innovation and biodiversity

Today, Dutch King Willem-Alexander officially inaugurated wind farm Hollandse Kust Zuid. To mark the occasion the king celebrated the completion of Vattenfall’s largest offshore windfarm to date together with executives of Vattenfall, BASF and Allianz on the beach of IJmuiden in front of a life-sized human turbine. The fossil free electricity generated from Hollandse Kust Zuid is expected to equal the consumption of 1.5 million households.  

Hollandse Kust Zuid is located in the North Sea, 18-36 kilometers off the Dutch coast between the towns of Scheveningen and Zandvoort. The 139 turbines have a total capacity of 1.5 GW, making it one of the largest offshore wind farms in the world. Its annual electricity production is expected to equal the consumption of 1.5 million households. Hollandse Kust Zuid is owned by Vattenfall, BASF and Allianz. The wind farm is expected to be fully operational in 2024 and will be serviced out of the port of IJmuiden.

“Vattenfall aims to be a leader in the energy transition and offshore wind is essential for energy security and to achieve Net Zero. The realization of a project of this magnitude makes me really proud and today is a great example of what we can achieve when partnering with industry. Hollandse Kust Zuid will not only contribute to reduce BASF’s carbon footprint but will also help meet local businesses and households demand for fossil free electricity,” says Helene Biström, Head of Business Area Wind at Vattenfall.

“Around half of the electricity from Hollandse Kust Zuid will be used to reduce the carbon footprint of our products at BASF sites in Europe. It is the first major investment of BASF in facilities for renewable power. To be part of making that happen makes me also personally very proud and happy. This marks another milestone on our way to climate-neutral production of chemicals,“ says Dr. Martin Brudermüller, Chairman of the Board of Executive Directors of BASF SE.

BASF aims to reduce its greenhouse gas emissions by 25 percent by the year 2030 and achieve net-zero emissions by 2050. Replacing fossil-based electricity with fossil-free electricity is an important lever to further bring down emissions.

“Allianz invests policyholder funds in renewable energy and owns more than 100 wind and solar farms. I am delighted that today we are opening our first direct investment in an offshore wind farm, together with BASF and Vattenfall. This underlines the ability of partnerships to catalyse action and bring climate solutions to life,” says Oliver Bate, CEO of Allianz.

Allianz is committed to achieve net-zero emissions by 2050 in its proprietary investment and Property & Casualty underwriting portfolios and already by 2030 within its own operations

Biodiversity at heart 

Several innovative techniques were used during the construction of Hollandse Kust, like a double bubble screen to dampen underwater noise during pile driving to limit the impact for harbour porpoises. Enlarged water replenishment holes in the foundations offer shelter for marine life inside the turbines, the first time the structure of a turbine itself is included in nature inclusive wind farm design. Boulders and rocks of varying sizes were used during the construction of scour protection. At several scour protection sites artificial rock reefs were added to make them more attractive to a wider number of fish, crabs and crustaceans.

Circularity – recyclable blades

Three turbines are fitted with recently developed recyclable blades. The resin used to ‘glue’ blades together will be easier to dissolve after the working life of the turbines, making it easier to disseminate the blades and reuse the different elements. 

Hollandse Kust Zuid is a key project in the ambitious goals that Dutch government has set to combat climate change and to provide the Netherlands with renewable energy for the next generation. In 2018, Hollandse Kust Zuid was awarded as the first subsidy-free wind farm in the world. The wind farm is expected to be fully operational in 2024 and will be serviced out of the port of IJmuiden.  

Grid connection  

Two offshore substations connect Hollandse Kust Zuid to the Dutch grid. These grid connections have been developed and will be operated by the Dutch TSO TenneT. As part of the Dutch offshore wind policy grid connections are publicly funded, which ensures standardisation and subsequent cost savings. It gives wind farm developers certainty that they will not have to adjust their designs later.
