Electricity transmission system operator (TSO) in The Netherlands TenneT, Danish TSO Energinet.dk, and Germany’s TenneT TSO have signed a trilateral agreement to develop a large windpower hub in the North Sea.

In June last year, TenneT revealed plans to develop the large renewable European electricity system in the North Sea.

TenneT is also carrying out discussions with other potential partners to form a multi-party consortium for developing the North Sea windpower hub. These include other North Sea TSOs and infrastructure companies.

TenneT’s chief executive officer (CEO) Mel Kroon said: “This project can significantly contribute to a completely renewable supply of electricity in Northwest Europe.

“TenneT and Energinet.dk both have extensive experience in the fields of onshore grids, the connection of offshore wind energy, and cross-border connections.

“TSOs are best placed to play a leading role in the long-term development of the offshore infrastructure.”

“TSOs are best placed to play a leading role in the long-term development of the offshore infrastructure. I am happy that we are going to take this step with our Danish colleagues and I look forward to the participation of other transmission system operators and possibly other partners.”

With the development of the new hub, TenneT and Energinet.dk intend to make energy transition across Europe feasible and cost-effective. The two TSOs plan to build one or more islands, to be named Power Link Islands, in the middle of the North Sea (Dogger Bank), with interconnections to surrounding countries.

The Power Link Islands can be connected to several facilities, with possible generation capacity ranging from 70,000MW to 100,000MW. Electricity generated can be distributed and supplied through direct current lines to the North Sea countries of the Netherlands, Germany, Norway, the UK, Denmark, and Belgium.

The transmission cables will simultaneously operate as interconnectors between the energy markets of these European countries, while enabling them to trade.
