TenneT has awarded the Van Oord-Hellenic Cables consortium the assignment to supply and install sea and land cables for the Hollandse Kust (South) Alpha project.
The 700 MW grid connection will transmit offshore wind energy to electricity users in the Netherlands.
Hollandse Kust
Two wind farms with a joint capacity of 700 MW are under construction in the Hollandse Kust (South) wind farm zone, 22 km off the coast of the Dutch Province of South Holland. TenneT was chosen by the Dutch government to manage the offshore grid.
Design, Manufacture, Cable Laying and Connecting
Its assignment for the Van Oord–Hellenic Cables consortium covers the design, the manufacture of 220 kV cables, the cable-laying operation, and connecting the wind farm to the Maasvlakte high-voltage station. The 42-km-long connection will run from the offshore Alpha substation to the onshore station located at the Maasvlakte 2 area, Rotterdam.
Hollandse Kust Beta Sea Cables Project
The Van Oord-Hellenic Cables consortium has also been chosen to deliver and install cables for the Hollandse Kust (South) Beta sea cables project. This assignment includes manufacturing and laying a 66 kV marine cable between the Alpha and Beta platforms.
The Hollandse Kust (South) Alpha grid connection must be ready by 2021, and the Beta in 2022.
