Windpark Fryslân cables installed

The array cables for the Dutch
Windpark Fryslân project have been installed and testing is underway to ensure they are ready for operations. The cables connect the wind turbines to the nearby Breezanddijk transformer station for integration into the grid.

Windpark Fryslân consists of 89 Siemens Gamsea SWT-DD-130 wind turbines and is being built in the IJsselmeer near Breezanddijk and will be the largest inland water wind farm worldwide. When full operations are achieved this year, the wind farm is expected generate around 1.5 terawatt hours (1,500,000 megawatt hours) of power annually, enough green electricity to power approximately 500,000 households.

The project is being built by contractor consortium Zuiderzeewind, which consists of Siemens Gamesa Renewable Energy and Van Oord Offshore Wind. Once the project is built, Siemens Gamesa Renewable Energy will be responsible for its maintenance and management for 16 years.

Due to the shallows in the IJsselmeer and the width of the locks, it is not possible to work with standard offshore wind equipment. To this end, Van Oord built a unique work platform, the size of half a football field, the so-called 'Sarens Soccer Pitch'. On top of this working platform is a large crane with which the foundations are installed.

The wind turbines are currently being installed in a 'cluster', in the shape of a hexagon, in the IJsselmeer. This shape ensures that the wind turbines restrict the view of the horizon as little as possible.

In addition to the 89 wind turbines at Breezanddijk, Windpark Fryslân consists of a newly constructed nature island at Kornwerderzand and a special transformer station on Breezanddijk, which will be open to the public from next summer.

Eneco has signed a 15-year PPA for the 1,500 GWh/year wind farm. In their contract, Eneco and Windpark Fryslân have agreed that large consumers of energy in the province of Fryslân will also have the option of purchasing sustainable energy from the wind farm.
