The Van Oord-Hellenic Cables consortium has secured a contract from Dutch transmission system operator TenneT to supply and install sea and land cables to connect the Hollandse Kust (South) Alpha offshore wind farm to the grid.
The 700MW grid connection will supply offshore wind energy to electricity users in the Netherlands.
Two wind farms, with a total capacity of 700MW, are being built in the Hollandse Kust (South) wind farm zone, 22km off the coast of South Holland.
The Dutch government chose TenneT to manage the offshore grid.
Under the contract, Van Oord-Hellenic Cables consortium will design, manufacture 220kV cables, lay the cables, and connect the wind farm to the Maasvlakte high-voltage station.
The 42km cable will be laid between the offshore Alpha substation and the onshore station at the Maasvlakte 2 area in Rotterdam.
Van Oord CEO Pieter van Oord said: “Offshore wind is an important part of the transition to sustainable energy in the Netherlands. This major offshore grid connection will bring wind energy to end users. We are excited to take on this project for TenneT with our partner Hellenic Cables.”
The Van Oord-Hellenic Cables consortium has also won another contract to deliver and install cables for the Hollandse Kust (South) Beta sea cables project.
Work under this contract includes manufacturing and laying a 66kV marine cable between the Alpha and Beta platforms.
TenneT CEO Manon van Beek said: “With this new tender for the offshore grid, we are again, according to the Energy Agreement, taking an important next step towards more sustainable electricity production at sea.”
The Hollandse Kust (South) Alpha grid connection must be completed by 2021 and the Beta in 2022.
Hellenic Cables general manager Alexios Alexiou said: “We are delighted that this prestigious offshore wind farm project was awarded to Hellenic Cables in cooperation with our partner Van Oord and driven by our combined ability to supply and timely install competitive and technologically innovative cable solutions.
“We are proud to contribute to the Dutch government’s goal to achieve its target of a total of 4.5GW of offshore wind energy production capacity by 2023.”
