Offshore Grid Hollandse Kust (noord) - Documentation
The future 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 will be operational in 2023.
A permit for the development of Hollandse Kust (noord) Wind Farm Zone Site V (700 MW) will be issued by the Dutch Government. Offshore wind farm developers can apply for this permit via a tender procedure. The documentation below regarding the offshore grid connection serves as background information for offshore wind farm developers to prepare their bid.
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.
General questions can be submitted to netopzee(at)tennet.eu.
Please note answers will be published in an anonimised format.
Platform information package:
The platform information package (including plotplans) for Hollandse Kust (noord) can be requested by wind developers preparing for the offshore wind tender Hollandse Kust (noord) via netopzee(at)tennet.eu.

This memo specifies the root loci of the calculated harmonic impedances at the 380 kV substation Beverwijk, the connection point to the onshore grid. These root loci can be used by the wind farm developers to verify their compliance with the harmonic requirements.Download Download

If the inter-array cables of site V near and/or cross 220 kV export cables of TenneT, a proximity and/or crossing agreement shall be agreed between the parties. For information purposes, TenneT publishes this model Crossing Agreement. The Crossing Agreement may be subject to any amendments that TenneT may deem necessary. A Proximity Agreement will – where applicable - be based on the same principles as incorporated in the Crossing Agreement, however taking into account the differences between a cable crossing and a situation where cables will be installed in each other's proximity.Download Download
