What are the technical specifications of the wind farm?
The Windpark Noordoostpolder utilizes a hybrid configuration of onshore and near-shore turbines to achieve its total installed capacity of 429 MW. The facility comprises 86 individual wind turbines, divided into two distinct technological groups based on location and manufacturer. This mixed fleet allows the park to maximize energy capture across different terrain and water conditions within Flevoland.Turbine Configuration
The near-shore section consists of 48 turbines manufactured by Siemens, each rated at 3 MW. These units are positioned in the water to take advantage of stronger and more consistent wind speeds typical of near-shore environments. The onshore section features 38 turbines from Enercon, specifically the E-126 model, with a higher individual capacity of 7.5 MW each. The combination of these two types results in the park's aggregate capacity.| Turbine Type | Location | Manufacturer | Model | Unit Capacity | Quantity |
|---|---|---|---|---|---|
| Near-shore | Water | Siemens | 3 MW | 3 MW | 48 |
| Onshore | Land | Enercon | E-126 | 7.5 MW | 38 |
Operational Sub-Projects: Westermeerwind, NOP Agrowind, and Zuidwester
Windpark Noordoostpolder is composed of three distinct sub-projects: Westermeerwind, NOP Agrowind, and Zuidwester. These components combine onshore and near-shore installations to achieve the park's total capacity of 429 MW. The ownership structure involves the Koepel Windenergie Noordoostpolder, a partnership of agricultural entrepreneurs, and Innogy, a subsidiary of RWE.
Sub-Project Profiles
Westermeerwind is the near-shore component of the complex. It consists of 48 Siemens turbines with a combined capacity of 144 MW. This section is situated in the near-shore environment, distinguishing it from the onshore sections. NOP Agrowind is an onshore installation featuring 26 Enercon turbines. This sub-project contributes 195 MW to the total capacity. Zuidwester is the third component, also located onshore. It comprises 12 Enercon turbines with a total capacity of 90 MW.
| Sub-Project | Type | Turbine Count | Turbine Manufacturer | Capacity |
|---|---|---|---|---|
| Westermeerwind | Near-shore | 48 | Siemens | 144 MW |
| NOP Agrowind | Onshore | 26 | Enercon | 195 MW |
| Zuidwester | Onshore | 12 | Enercon | 90 MW |
The distribution of technology varies across the sub-projects. Westermeerwind utilizes Siemens technology for its near-shore location. In contrast, both NOP Agrowind and Zuidwester employ Enercon turbines for their onshore installations. The combined capacity of these three sections totals 429 MW, making Windpark Noordoostpolder one of the largest wind farms in the Netherlands upon its completion in 2017. The operational status of the park is operational, with the Koepel Windenergie Noordoostpolder and Innogy serving as the primary owner-operators.
How does the new wind farm compare to previous installations?
The Windpark Noordoostpolder represents a significant technological and operational shift from the preceding generation of wind infrastructure in the region. Prior to the 2017 commissioning of the new facility, the area was characterized by a dispersed arrangement of older turbines. Specifically, the previous installation consisted of 55 individual wind turbines: 50 units located along the Westermeerdijk and 5 units situated on the Zuidermeerdijk. This earlier configuration required a larger spatial footprint and involved a higher count of mechanical components to achieve comparable energy output.
The new wind farm demonstrates substantial efficiency gains through advanced turbine technology. The grounding data indicates that the technological improvements are so pronounced that a single new turbine can match the output of 50 of the older units. This ratio highlights the dramatic increase in capacity per unit, allowing for a more consolidated and potentially less visually intrusive installation despite the higher total capacity of 429 MW. The ability to replace 50 legacy turbines with just one modern unit underscores the rapid evolution in wind energy conversion efficiency.
The transition involved the systematic dismantling of the older infrastructure. The 55 previous turbines, having served their operational life, were removed to make way for the new configuration. This process reflects the lifecycle management of wind assets, where older, less efficient models are decommissioned to accommodate newer, higher-capacity technology. The dismantling of the Westermeerdijk and Zuidermeerdijk turbines was a necessary precursor to the full operational status of the Windpark Noordoostpolder.
The comparison between the old and new installations illustrates the broader trend in the Netherlands' wind energy sector: moving from numerous, smaller-capacity turbines to fewer, high-output units. This shift not only improves energy yield per turbine but also optimizes land use in the Flevoland region. The partnership between Koepel Windenergie Noordoostpolder and Innogy (RWE) facilitated this upgrade, leveraging the expertise of more than 100 local agricultural entrepreneurs and the technical resources of the German energy company. The result is a facility that, upon its 2017 completion, stood as the largest wind farm in the Netherlands, maintaining that status through at least 2019.
Environmental and Geographical Context
Windpark Noordoostpolder is situated in the province of Flevoland in the Netherlands, occupying a strategic position along the dikes bordering the IJsselmeer. This location is critical for the dual nature of the facility, which integrates both onshore and near-shore wind energy generation. The IJsselmeer serves as the primary water body for the near-shore components of the wind farm, allowing turbines to be positioned in shallow waters that facilitate construction and maintenance while maximizing wind exposure compared to purely inland sites. The geographical context of the North East Polder (Noordoostpolder) provides a flat, open landscape that is ideal for wind energy harvesting, minimizing turbulence caused by topographical variations.
Near-Shore Turbine Deployment
The near-shore section of the wind farm utilizes specific water depth conditions to optimize turbine placement. The turbines in this segment are installed in waters with depths ranging from 3 to 7 meters. These relatively shallow depths are characteristic of the IJsselmeer’s coastal zones and allow for specific foundation types that are cost-effective and structurally sound for the installed capacity of 429 MW. The operational status of these turbines, commissioned in 2017, relies on the stability of these shallow water environments, which are less prone to the extreme wave action found in deeper offshore locations. The integration of near-shore turbines expands the effective land area for energy production without significantly encroaching on agricultural land further inland.
Infrastructure and Ecological Integration
The construction of the wind farm required careful planning to accommodate both energy infrastructure and local maritime traffic. A stone guided dam was constructed to manage shipping routes and protect the turbine foundations. This infrastructure element serves a dual purpose: it diverts shipping traffic away from the most densely packed turbine areas, reducing the risk of collision and operational disruption, and it creates designated areas for flora and fauna. The stone guided dam acts as an artificial reef, encouraging marine biodiversity and providing habitats for local species. This approach reflects a broader trend in energy infrastructure to mitigate environmental impact through integrated design. The partnership between Koepel Windenergie Noordoostpolder and Innogy, a subsidiary of RWE, has emphasized the involvement of more than 100 agricultural entrepreneurs, ensuring that the geographical and ecological context is managed with local stakeholder input.
