TenneT has unveiled what it calls a wind power booster concept for Germany to help unlock the potential of offshore wind in the North Sea.

The concept would be made up of three interconnected offshore grid systems to combine 6 GW of power.

The grid connection points must be located in Schleswig-Holstein, Lower Saxony and Bremen.

TenneT said this creates the best conditions for hydrogen production and thus supports the decarbonization of the industry.

The company added that direct current (DC) lines on land and at sea are designed in a mesh system.

“At the grid connection points, the lines have to be interconnected in so-called multi-terminals,” he said.

TenneT said this makes the system more robust, efficient and cost effective, and helps minimize space consumption and environmental interventions.

The LanWin modular hub in the North Sea would allow up to 6 GW of offshore wind power to be directly connected and for the first time to directly connect three connection systems to the offshore grid.

In addition, it offers the possibility of international networking, such as the Danish Energy Island which will be completed in 2032, TenneT said.

He said that currently all DC systems at sea and on land are planned as point-to-point connections.

TenneT now proposes to network these three connections with a power of 2 GW for the first time at sea and on land with other direct current connections.

The concept of a wind power booster could be implemented by 2032, the transmission grid operator said.

“With this, the existing plans for connecting a cluster of wind farms in the German North Sea could be significantly accelerated,” TenneT said.

The system could also be extended by other modules and allow networking with neighboring European countries.

The managing director of the German offshore wind trade group WAB, Heike Winkler, said: waters.

“It’s about further harnessing the potential of long-term demand for climate-friendly electricity, even beyond the framework established today. Therefore, we are happy to engage in dialogue with all stakeholders.
