TenneT picks Van Oord, Hellenic for Hollandse Kust South

Consortium to supply and install subsea and onshore cables for giant offshore wind farm being developed in the North Sea

Dutch-German transmission system operator TenneT has selected the Van Oord and Hellenic Cables consortium to supply and install 220kV subsea and onshore cables for the Hollandse Kust South Alpha project, an offshore wind farm being developed in the North Sea.

The partners will lead on the 700MW cable connection, which will transmit offshore wind energy to electricity users in the Netherlands from the 700 MW under-construction Hollandse Kust (South) wind farm.

LMR Drilling was contracted separately to carry out horizontal directional drilling.

Under the deal, Van Oord and Hellenic will handle the design, manufacture and installation of subsea and onshore cables, and connecting these cables to the Maasvlakte high‑voltage substation.

The consortium is also the preferred contractor for the supply and installation of cables for the Hollandse Kust South Beta wind farm zone.

“The realisation of a 66kV subsea cable between the Hollandse Kust Zuid Alpha and Beta offshore platforms has been included as an option in the contract,” TenneT said in a statement.

The Alpha platform is scheduled for completion in 2021, the Beta platform in 2022.

“This new offshore grid contract conforms to the timeline set out in the Dutch National Energy Agreement, and represents another important step towards the development of large-scale offshore electricity production capacity,”said TenneT chief executive Manon van Beek.

“TenneT, and therefore the Netherlands as a whole, is well on track to realize 3.5GW of additional offshore wind farms, increasing the total offshore capacity to approximately 4.5GW by 2023,” he said.

Meanwhile, the tender procedure for the subsea cables and platforms for the Hollandse Kust Noord offshore grid project will start towards the end of 2018. In accordance with the new Roadmap for Offshore Wind Energy, a further 7GW of offshore wind energy capacity is expected to be constructed and connected to the grid by TenneT in the 2024-2030 period, the TSO said.

Earlier this week, TenneT started work on its NordLink subsea cable section in the German North Sea.

The NordLink interconnector is 623km long and will directly connect the energy markets of Germany and Norway for the first time, serving as an exchange between German wind energy and Norwegian hydropower.

The project is expected to be completed by 2020
