Plug German windfarms into Dutch grid, says TenneT

Plug German windfarms into Dutch grid, says TenneT
TenneT said some German offshore windfarms could be connected to the Dutch grid

Transmission system operator TenneT has suggested that German offshore windfarms in the western part of the German North Sea could be connected to the grid in The Netherlands.

TenneT said such a move could help Germany overcome bottlnecks in the grid on land. Getting electricity produced by offshore windfarms in the north of the country to power-hungry industry in southern Germany has long been an issue.

One such cost-effective solution could be a connection to Eemshaven. "Because this grid connection point is on the coast, it would be possible to save 100 km of underground cabling in Germany and thus around Ä200 million, bypassing bottlenecks in the German electricity grid," TenneT said.

The TSO said the necessary legal certainty could be achieved through a German-Dutch treaty, which would stipulate that German windfarms and grid connections continue to be subject to German regulation. 

In the Netherlands, TenneT is already investigating connecting to the UK by linking the future Ijmuiden Ver and East Anglia windfarms, creating an interconnector between the two countries.

In the German North Sea, TenneT currently has 10 offshore grid connection systems with a total capacity of 5.332 GW rgy from sea to land. This means that TenneT could provide more than 80% of the federal governmentís expansion target of 6.5 GW  of offshore wind capacity by 2020. By the end of 2023, TenneT willhave completed three additional grid connection systems, which will provide 8.032 GW of transmission capacity in the North Sea.

By 2027, three more connections will be implemented by TenneT or will be pending, according to the preliminary design of the land development plan of the German Federal Maritime and Hydrographic Agency. This will increase the transmission capacity in the German North Sea to almost 11,000 GW.
