What Westermeerwind does

Westermeerwind B.V. operates the largest nearshore wind park in the Netherlands, located in the IJsselmeer along the Noordoostpolder dikes. The asset comprises 48 Siemens turbines of 3 MW each for 144 MW total installed capacity, sufficient to supply electricity equivalent to 160,000 Dutch households. The wind park became fully operational in 2016 after nearly two decades of development since the company's 1996 founding by farmers Tjitte de Groot and Pieter Meulendijks. Core technology includes 44 km of submarine cabling connecting turbines to an onshore Siemens-built transformer station feeding TenneT's high-voltage grid, with specialized nearshore installation methods developed for shallow water depths of 4–7 m.

The company runs a community-led business model under a 2002 convenant that reserves financial participation for residents of Noordoostpolder, Urk, and former Lemsterland through share funds (Aandelenfonds), loan funds (Leningenfonds), and bond issuances (Obligatie-uitgifte 2024, EUR 5M raised, oversubscribed). All electricity output is sold to Eneco under a 15-year PPA, supplemented by a Dutch SDE subsidy top-up that guarantees a minimum revenue floor. The 12-employee operation also pursues community engagement through the 11Beaufort experience center, public boat tours, open days, a live-monitoring mobile app, and an Aircraft Detection Lighting System from Lanthan Safe Sky, with a one-year AI bird-detection radar pilot under way with Danish supplier DHI.

Revenue model

1. Electricity Sales to Eneco (PPA): Eneco purchases all electricity generated by the 144 MW wind park under a 15-year Power Purchase Agreement (PPA). This constitutes the primary revenue stream. The agreement is described as one of the largest wind PPAs in Eneco's history.
2. SDE Subsidy: Westermeerwind receives SDE (Stimuleringsregeling Duurzame Energie) subsidy, which tops up revenue to a guaranteed minimum when energy market prices are low, over a period of up to 15 years. Additionally received an investment subsidy at time of construction and receives an operational subsidy. The three subsidies together provided sufficient certainty for investment.
3. Community Share and Bond Participation: Revenue is not directly generated from this stream; rather, it enables community financing. The company issued shares (Westermeerwind Aandelenfonds, 17-year term) and bonds (Westermeerwind Obligatie-uitgifte, 5-year term at 7.5% annual interest) to local residents, with the bond issuance through Invesdor in 2024.

Direct peers

• NOP Agrowind: Operator of 26 turbines within Windpark Noordoostpolder alongside Westermeerwind. Co-initiator coordinated via Stichting Koepel Windenergie Noordoostpolder, making it the closest comparable nearshore Dutch wind farm with a similar community participation heritage.
• Windpark Krammer: Large Dutch cooperative nearshore wind farm developed by local communities and farmers on the Krammer sluice. Shares Westermeerwind's community-ownership DNA and Dutch nearshore operating model, making it a strong functional peer.
• Windpark Fryslân: Largest nearshore wind farm in the Netherlands (382 MW) in the IJsselmeer, with strong local cooperative participation. Closest at-scale analog of nearshore Dutch wind generation with community-driven governance.
• RWE Windpark Zuidwester: RWE-owned 12-turbine wind farm that, together with Westermeerwind and NOP Agrowind, constitutes the 86-turbine Windpark Noordoostpolder. Directly comparable utility-scale nearshore Dutch wind operator sharing the same dikes and grid interconnection.

Others

• Ventolines: Full-lifecycle wind energy service provider that has managed Westermeerwind's development, financing, construction supervision and operations since 2007. Comparable as an ecosystem partner rather than a competitor, and an indicator of replicable asset-management capability.
• Siemens Gamesa Renewable Energy: OEM and 15-year maintenance contractor for all 48 Westermeerwind turbines. Comparable as the technology and service backbone of the asset, though functioning here as supplier rather than peer operator.

Broad incumbents

• Ørsted (Netherlands): Global offshore-wind leader with Dutch offshore projects (e.g. Borssele). Comparable in wind generation activity and offtake relationships, though Ørsted is offshore-focused and far larger, with industrial rather than community-led ownership.
• Vattenfall (Netherlands wind): Operates large Dutch onshore and offshore wind portfolios (e.g. Wieringermeer, Hollandse Kust). Comparable as a Dutch utility-scale wind asset owner/operator with longer track record and broader portfolio diversification.
• Eneco: Westermeerwind's PPA offtaker and a major Dutch renewable-energy retailer that also owns and operates wind/solar assets. Comparable as a Dutch electricity off-taker, while also a buyer-of-last-resort competitor in the same wind generation market.

Regional players

• Windpark Bouwdokken: Smaller Dutch nearshore/community wind initiative. Comparable in the Dutch nearshore community-ownership model, though materially smaller in scale and earlier in lifecycle than Westermeerwind.
