Dutch renewable energy firm TenneT has planned to build a man-made island in the North Sea to set up a large electricity system, which would serve as an interconnector for supplying offshore wind power across European Union (EU) countries.
Connecting several offshore windfarms with a total capacity of about 30GW, the island’s generated power will be transmitted over direct-current cables to countries including the UK, the Netherlands, Norway, Belgium, Germany, and Denmark.

The cables will also serve as interconnections between energy markets, performing the roles of highways for international trade.
Under the project, the island will be equipped with a modular structure, with each module covering nearly six square kilometers.
TenneT’s CEO Mel Kroon said: "The success of the energy transition depends largely on the extent we mount a coordinated joint effort in Europe.
"Cooperation between national governments, regulators, the offshore wind industry, national grid administrators, and nature and environmental organisations is a precondition for achieving Europe’s environmental targets. The vision we have presented shows the relevance of cooperation in the North Sea."

By GlobalDataA sandbank around 100km off the east coast of England Dogger Bank has been considered a suitable location for constuction due to its shallow waters and a relatively high and stable wind speed. The shallow water will help reduce construction costs, while the wind conditions will help generate a high yield.
