Offshore Wind Energy Action Plan
Due to rising costs and less demand for electricity than expected, development of offshore wind energy is coming to a standstill in many countries. To prevent this from happening in the Netherlands as well, the Dutch Cabinet presented the Offshore Wind Energy Action Plan on 16 September 2025. This includes measures to financially support the construction of new wind farms. The plan also provides solutions to further stimulate demand for offshore wind energy.
You can read more about the action plan in the news item: Action plan supports construction of offshore wind farms.
No influence on Nederwiek I-A tender round
The action plan does not apply to the current tender round for Nederwiek Wind Farm Site I-A, which will start in October.
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:
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?
First, we check whether the application contains all the necessary information. We then assess whether the project is feasible. If the application meets these requirements, we proceed with the further evaluation of the application.
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:
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
We regularly upload new versions of important documents for your application on this page. Keep an eye on this page and our (English language) newsletter for updates.
You can submit your application via our digital application environment. You will find the link on this page as soon as the application period opens.
Would you like to see what we require from you in advance? Then take a look at the draft application form and draft operating calculation. Do you have any comments or questions? Email us at woz@rvo.nl.
In the documents 'Voorbeeld aanvraagformulier Nederwiek I-A' and 'Toelichting op bijlagen bij aanvraag Nederwiek I-A' (only available in Dutch), you will find all the practical information regarding your application. This includes details on what you need to submit and which information we require from you.
In the application form, we refer to the official regulations (Ministerial Order) for Nederwiek I-A published in the Government Gazette (Staatscourant). The Ministerial Order contains the legal information about the process for granting the permit for the construction and operation of wind farm.
Only available in Dutch.
On 1 January 2024, the Offshore Wind Energy Implementation Regulation was amended by adding a new test for various possible risks. The Investment Assessment Bureau (BTI) carries out this test. This form is required for this. You provide information about safety here. You must include this information with your permit application.
Only available in Dutch.
In the operating calculation, you report all the costs and revenues of the wind farm. The model then automatically calculates the financial result of your project over its entire term. This prevents your bid from being unrealistic. Furthermore, under the Offshore Wind Energy Act, we may only issue a permit if there is sufficient confidence that the wind farm is economically viable.
Only available in Dutch.
The permit holder must adhere to a number of regulations when carrying out the project. The draft permit regulations contain the regulations that will, in any case, be included with the final permit. We determine the final regulations with the permit. These may depend on what you state or promise in your bid.
Only available in Dutch.
Only the winner of the permit must provide a bank guarantee or deposit. This is an additional assurance for us that the winner of the permit will realise the wind farm on time. If the winner does not complete the wind farm on time, the Government will collect the deposit worth € 100 million in stages.
For one month's delay, the fine is € 10 million. We keep the bank guarantee or deposit in a safe and return it if the winner of the permit completes the wind farm on time.
Only available in Dutch.
You use the Wind Farm Site Decision (WFSD) to prepare your application. It contains site boundaries and the conditions you must adhere to when building and operating the wind farm. These conditions include, among other things, nature conservation.
The final WFSD was published in May 2025. You can find the final WFSD for the Nederwiek (South) I-A site on the Energy Projects Office page (in Dutch only). This WFSD became irrevocable on 28 June 2025.
The draft WFSD was published on 21 November 2024. You could submit comments on the draft WFSD until 2 January, 2025. Read more about (the process surrounding) the WFSD (Dutch only).
For the regulations we provide you with an unofficial translation:
Together with our partners, we are conducting 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.
