Energy development

The construction

The wind farm was built by the construction combination Egmond. This is a joint venture between Ballast Nedam and the Danish wind turbine manufacturer Vestas. Both companies have extensive experience in offshore wind energy.


Electricity production

It starts with the wind turning the blades, or rotor blades. These rotor blades are attached to the main shaft. The rotational movement is sped up in a gearbox. The main shaft drives the generator.
