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 Borssele 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: 

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:

  • The highest scoring party for a plot receives the permit to build and operate the wind farm.

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 study will not be fully completed before the tender submission opens for Nederwiek I-A. At this stage, no measures will be implemented for the tender submission. However, based on the results, certain measures or conditions may be required. We expect to have more clarity on this before the permit is granted.

Review our webinar

On 10 June, we organised a webinar to explain the tender procedure for Nederwiek I-A. You can review this webinar, the accompanying presentation and Q&A sessions.
