The jacket foundation for TenneT’s Hollandse Kust (noord) substation has been installed in a joint operation by DEME Offshore and Scaldis SMC. The 2,100-tonne jacked installation has been completed by the heavy lift vessel Gulliver. 

DEME said the installation was performed on schedule despite the challenging weather conditions. The topside of the Hollandse Kust (noord) substation will be installed during the summer of 2022. DEME has also secured a deal to install jacket for Hollandse Kust (west Alpha) during the summer of 2022 while the topside will be installed in 2023.

The offshore platforms Hollandse Kust (noord) and Hollandse Kust (west Alpha) platforms will be located in the North Sea along the Dutch coast and will be operational by respectively 2023 and 2024.

In 2030, 40 percent of the electricity demand of the Netherlands will be supplied by the electricity of offshore wind farms. TenneT realises the grid connections for these wind farms. These 700 MW platforms will be the fifth and sixth large-scale grid connections for offshore wind energy in the Netherlands, built and operated by TenneT.

The first high-voltage connections for the wind farms near Borssele are now operational, and will be followed by the connections for Hollandse Kust (zuid) in 2022. TenneT will realise approximately 9.6 GW of high-voltage connections in the Dutch North Sea by 2030.
