According to the plans, a 2.3 square mile (6 square kilometers) island will be created at the northeast end of the Dogger Bank, a relatively shallow area in the North Sea with high wind readings. Thousands of wind turbines will be placed around the island, with short alternating-current links to the island.
The island will be part of the North Sea Wind Power Hub project and will include an airport, harbor and converters to change wind-generated electricity from alternating current to direct current which would be transmitted over cables to the Netherlands, the United Kingdom, Belgium, Norway, Germany and Denmark.
The project’s backer is Dutch power grid operator TenneT. The company recently released a report claiming the island will be billions of euros cheaper than conventional windfarms and international power cables. Right now, costs estimates are projected to be over £1.3 billion ($1.75 billion).
