Information for wind farm developers
In the Netherlands, TenneT will develop 20 GW offshore grid connections around the year 2030. The documentation below serves as background information for offshore wind farm developers to prepare their bid in upcoming wind farm zone site tenders.
Future offshore wind parks will be connected through 66 kV inter-array cables to an offshore 2 GW AC/DC converter station from TenneT. The offshore converter station will be based on HVDC technology. Using 2 GW high voltage (525 kV) export cables the electricity is transported to shore where the DC is converted back to AC again so the green energy can be fed into the onshore grid.
Tender IJmuiden Ver sites I - IV
The permits for the development of the IJmuiden Ver Wind Farm Zone Sites will be issued by the Dutch Government. Offshore wind farm developers can apply for this permit via a tender procedure. The RVO website provides information about the tender and permit to develop IJmuiden Ver Wind Farm Zone (IJVWFS).
On offshorewind.rvo.nl you can find all available site data on soil, wind and water conditions and obstructions on IJVWFS.

Consultation 2GW HVDC offshore grid connection system
Documentation
To ensure the 2 GW standard has an optimal design from a system perspective, TenneT initiated a consultation process in 2019 with relevant stakeholders on all relevant interfaces with offshore wind farm developers (OWFs). The documentation below contains the result of this consultation process. The consultation process itself is described in the concluding report. The position papers per topic include a more in-depth description and substantiation of the positions.
You can find all relevant documents in the zip file below.
NB: please note that some insights have changed since the consultation was held. The most up-to-date information on relevant interfaces between TenneT and the offshore wind farm are included in the model agreements of the CTA and REA.
Green Grid operator
TenneT strives to enhance the energy transition in a sustainable manner, leading the way in maximizing our societal contribution and minimizing our impact. We identified 4 CSR-topics where we want to make a difference: Climate, Circularity, Nature and Human rights. In the leaflet, you can read how we realise our sustainability ambitions via our projects.
Hollandse Kust (noord)
Documentation
The grid connection 'Hollandse Kust (noord)' consists of one connection of 700 MegaWatt (MW). The offshore platform will be connected by cables to the high-voltage substation in Beverwijk. The offshore grid connection is made operational in 2023. You can download the documentation for this project below for reference.
NOTE:
The RVO website provides information about the tender and permit to develop Hollandse Kust (noord) Wind Farm Zone (HKNWFZ).
On offshorewind.rvo.nl you can find all available site data on soil, wind & water conditions and obstructions on HKNWFZ.
Hollandse Kust (west)
Documentation
The future grid connections for the Hollandse Kust (west) Wind Farm Zone will consist of two 700 MegaWatt (MW) grid connections. Hollandse Kust (west) Alpha will be ready to provide for the connection for Wind Farm Zone VI in 2024. Hollandse Kust (west) Beta will be ready to provide for the connection for Wind Farm Zone VII in 2026. Each grid connection system consists of a platform and cables to be connected to the onshore grid at the high-voltage substation in Beverwijk. You can download the documentation for this project below for reference.
NOTE:
The RVO website provides information about the tender and permit to develop Hollandse Kust (west) Wind Farm Zone (HKWWFZ).
On offshorewind.rvo.nl you can find all available site data on soil, wind & water conditions and obstructions on HKWWFZ.
