DEME Group announced that it has completed the installation of the export cable for the TenneT Hollandse Kust Zuid grid connection project. The project provides a route for the electricity by the Hollandse Kust Zuid wind farms to be transmitted ashore.

With its cable vessel
Living Stone DEME installed 2 x 34 km export cable and 8 km interlink cable. The complex project included the crossing of the Maasmond shipping route, characterised by heavy traffic to and from the Port of Rotterdam.

The Hollandse Kust (zuid) site consists of two sites,
Hollandse Kust Zuid 1&2 and Hollandse Kust Zuid 3&4, and is being developed by Vattenfall, which secured the rights to the projects with subsidy free bids in March 2018 and July 2019. They are located between 18 and 36 kilometers off the Dutch coast, between The Hague and Zandvoort. They will be fitted with 140 units of Siemens Gamesa 11 MW, SG 11.0-200 DD offshore turbines.

Once the wind farm is operational, the 140 wind turbines will produce more than 6 TWh of green electricity annually.
The project is expected to be fully operational in 2023.
