Windplanblauw

Windplanblauw

The wind turbines are part of the Windplanblauw project, which comprises a total of 61 new turbines. Through the green energy produced by the wind turbines, this project is making a substantial contribution to the Energy Agreement in the Province of Flevoland. In this way, Ballast Nedam is contributing to the energy transition with the construction work for Windplanblauw.

The project in brief

The new wind turbines are part of an initiative by SwifterwinT and Vattenfall: a wind farm in the municipalities of Dronten and Lelystad, where 74 existing wind turbines are being replaced by 61 modern turbines with a higher capacity. The wind farm has a total installed capacity of over 335 MW. A total of 37 turbines will be placed on land and 24 in the water of the IJsselmeer lake.

The foundations for the 24 turbines in the IJsselmeer are designed and realised by Ballast Nedam. The new foundations will replace the 28 wind turbines of the current 'Irene Vorrink' wind farm, which was also built by Ballast Nedam. Ultimately, the 24 wind turbines will each generate about 6 Megawatt of power, which is 5,4 Megawatt extra power compared to the old turbines.

Nearshore locations

Project Windplanblauw is located in shallow water, on the border of onshore (land) and offshore (sea). We refer to this location as 'nearshore'. This is where our expertise lies and where we can apply our maritime knowledge, combined with our expertise in building on the land.

Unique cofferdam construction

For this project, Ballast Nedam developed a unique solution for the installation of land-based turbines on water. We combine the upper part of the foundation solution, which is normally used on land, with the lower part of a marine solution. This creates a cofferdam construction that forms the basis for the turbine foundations. Through this unique cofferdam construction, we are applying a proven technique.
