Onshore Segment of the "Windplanblauw" Wind Farm Project

The Windplanblauw project is a large-scale wind energy initiative located in the northwestern corner of Flevoland, Netherlands, including a part of the IJsselmeer. It is a repowering project where older wind turbines are replaced with more efficient and powerful ones. The project is driven by a consortium, Molenrak, which includes Vattenfall and SwifterwinT.
Onshore Segment: The onshore portion of the Windplanblauw project consists of 37 Vestas V162-5.6 MW wind turbines, with a total capacity of 207 MW. This will provide enough energy to power 270,000 households.
Balance of Plant: The onshore part also includes the construction of 37 foundations, each with a 22-meter diameter, and the installation of 1300 vibro piles.
GDS Substation: A 150 kV GDS substation is part of the infrastructure, which is connected to the Tennet station via a 6 km export cable.

Challenge

The Windplanblauw project faced several significant challenges, including the complexities of repowering older turbines with larger, more powerful ones while maintaining efficiency. Navigating the intricate permitting process required close collaboration with local authorities and environmental agencies. The logistics of transporting and installing large turbines, especially in challenging weather, posed technical hurdles. Coordinating a wide range of contractors and stakeholders required seamless communication and project management. Environmental conditions, such as soil stability, added complexity to foundation design. Managing the tight timeline and risk mitigation was critical to staying on schedule. Additionally, maintaining effective stakeholder engagement was essential for project success

Solution

To address the challenges, the Windplanblauw project employed a strategic repowering approach, optimizing the layout of larger turbines within the available space. The permitting process was streamlined through proactive engagement with local authorities and environmental groups. Advanced logistics planning ensured efficient turbine transportation and installation, even in adverse weather conditions. The integrated project management approach, powered by the Aryo platform, facilitated seamless coordination among contractors and partners, allowing for efficient contract, risk, and document management.

Results

24% increase in turbine efficiency by replacing 74 older turbines with 61 new, more powerful Vestas V162-5.6 MW turbines, producing enough energy to power 270,000 households.

The project helped achieve significant CO2 emissions reduction, supporting the Netherlands' renewable energy goals.

Improved project management through the Aryo platform, which streamlined operations and facilitated real-time communication across all stakeholders, optimizing processes and saving resources.

Completion of the 150 kV GDS Substation, which supports energy transmission to the Tennet station, strengthening the country’s energy infrastructure.
