Location of Nederwiek Site I-A
Which area is involved?
The Nederwiek I-A (NW I-A) Site starts approximately 95 km off the west coast of Texel. The total surface area of the NW I-A Site is approximately 149.2 km2. This includes the maintenance and safety zones.
Grid operator TenneT is installing the offshore grid that will connect the wind farm to the onshore high-voltage grid. This is how the wind energy generated ends up on our electricity grid. The wind farm will be connected to a TenneT substation platform for this purpose. The platform has a 2 GW direct current (DC) connection to an onshore substation in the Borsele area. The intention is that Nederwiek I-B will also be connected to the platform later. This means that two 1 GW wind farms will connect to one platform. The DC connection ensures that the voltage on the electricity grid remains constant.
More information about the planning of the offshore grid can be found in the Offshore Wind Energy Development Framework:
When can you apply?
The application period for the permit for this site opens on 16 October 2025 and closes on 30 October 2025 17:00 hour.
Review our webinar
On 10 June, we organised a webinar to explain the tender procedure for Nederwiek I-A. You can review this webinar and the accompanying presentation.
What conditions do you have to meet?
Applications are assessed based on the procedure of a comparative test with a financial bid. This means you earn points based on several ranking criteria. The application with the highest score will receive the permit. For your permit application, we will at least weigh the following components when determining its score:
- certainty that you will realise the wind farm;
- contribution of the wind farm to energy supply;
- amount of your financial bid.
Moreover, there are additional criteria that count towards the assessment of the permit application. For the Nederwiek I-A site, the emphasis is on reducing the negative impact of a wind farm on nature in the North Sea and on ideas that can strengthen nature.
The content and weighting of the various criteria can be found in the Ministerial Order on permitting for Nederwiek I-A (Dutch only, translation will be available soon).
Research into national security of offshore wind energy
The Ministry of Climate and Green Growth is conducting research into risks to national security associated with offshore wind farms. This research specifically focuses on the use of components from 'third countries' (countries that are not members of the European Union). These are countries with offensive (cyber) programmes that continuously carry out offensive intelligence activities. Such activities could pose a threat to the interests of the Netherlands and its allies.
Are there risks to national security with certain components? Then you may need to comply with strict conditions or restrictions when using these components in the construction of a wind farm.
This research may not be completed before the tender registration opens for Nederwiek Site I-A. However, it may be that, based on interim results, you have to take restrictions or conditions into account for these wind farms.
Preparing your application
On this page, we will regularly upload new versions of important documents for your application. Keep an eye on this page and our (English language) newsletter for this.
Wind Farm Site Decisions
Another document you use when preparing your application is the Wind Farm Site Decision (WFSD). The final WFSD for Nederwiek I-A was published in May 2025. This contains the boundaries and coordinates of the site and the conditions you must adhere to when building and operating the wind farm. The conditions are there, among other things, to protect nature.
Read the Wind Farm Site Decision on permitting for Nederwiek I-A (Dutch only).
For the regulations we provide you with an unofficial translation:
The draft WFSD was published on 21 November 2024. It was possible to provide feedback on the draft WFSD up to 2 January 2025. Read more about (the process surrounding) the WFSD (Dutch only).
Site studies
Together with our partners, we are conducting location site studies in the Nederwiek Wind Farm Zone. The data and reports from the site studies are published on offshorewind.rvo.nl (English). With the data from these site studies, you can plan and optimise the design of the offshore wind farm.
View the site studies for the Nederwiek Wind Farm Zone.
After your application
- We assess all applications together with experts;
- A statutory period of 13 weeks applies to the assessment;
- The highest scoring party for a plot receives the permit to build and operate the wind farm.
