Windplanblauw

Energy transition

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 has contributed to the energy transition with the construction work for Windplanblauw.

Green power and extra capacity

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and Vattenfall: a wind farm in the municipalities of Dronten and Lelystad, where 74 existing wind turbines have been replaced by 61 modern turbines with a higher capacity.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 are placed on land and 24 in the water of the IJsselmeer lake.

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

Nearshore locations

Project Windplanblauw was 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 combined the upper part of the foundation solution, which is normally used on land, with the lower part of a marine solution. This created a cofferdam construction that formed the basis for the turbine foundations. Through this unique cofferdam construction, we have applied a proven technique.
