Consider switching to Siemens Gamesa: Similar focus on wind energy solutions and global reach.
Vestas' flagship offshore turbine is the V236-15.0 MW™ with 115.5-meter blades and a 236-meter rotor diameter, capable of producing up to 80 GWh per year per unit. Siemens Gamesa has historically led offshore installations by volume, but Vestas has secured 10+ GW in firm orders and preferred supplier agreements for the V236, including a 1.38 GW contract for RWE's Vanguard West project in the UK (92 units). Key differentiator: Vestas brings 200+ GW of total installed capacity and the industry's largest service network (12,000+ technicians in 72 countries), while Siemens Gamesa has deeper offshore-specific install history but has faced well-publicized quality issues and financial losses in recent years.
Vestas offers tiered Active Output Management® (AOM) service contracts. AOM 1000–3000 provide flexible, lower-scope agreements where operators choose their commitment level and access Vestas capabilities on a time-and-material basis. AOM 4000 includes a time-based availability guarantee with compensation for downtime below the guaranteed threshold. AOM 5000 is the most comprehensive, featuring an energy-based availability guarantee that optimizes output by scheduling maintenance during low-wind periods, with all parts, consumables, and major components included. Contracts can run up to 25 years — for example, a recent 74 MW project in Finland included a 25-year long-term service agreement.
Yes. Vestas operates a dedicated multibrand service division that currently maintains 8+ GW of non-Vestas turbines across all major OEM platforms globally. The multibrand service includes the same AOM maintenance packages, access to ShopVestas' 100,000+ spare parts catalog, and digital tools like VestasOnline and the Blade Asset Management application, which provides blade inspection data regardless of turbine brand. This allows fleet operators with mixed-manufacturer portfolios to consolidate under a single service provider.
EnVentus™ is Vestas' latest-generation onshore wind turbine platform, introduced in 2019, combining proven designs from the 2 MW, 4 MW, and 9 MW platforms into a modular architecture. It includes four variants: V172-7.2 MW (with flexible ratings of 7.2, 6.8, and 6.5 MW), V162-7.2 MW, V162-6.2 MW (with a swept area exceeding 20,000 m²), and V150-6.0 MW. The platform has 12+ GW installed across 23 countries. Its full-scale converter ensures compliance with diverse grid code regulations, and its modular nacelle design allows for service flexibility and upgrades over the turbine's operational lifetime.
Vestas has developed a chemical recycling process through the CETEC project (in partnership with Aarhus University, Olin, and Stena Recycling) that breaks down epoxy resin into virgin-grade materials — without requiring any change to existing blade design or composition. This can be applied to blades currently in operation and to legacy blades already in landfill. Vestas has committed to producing a 100% recyclable rotor by 2030 and achieving zero-waste turbines by 2040. Current EnVentus turbines already achieve 84–87% recyclability. WindEurope estimates approximately 25,000 tonnes of blades reach end-of-life annually, making this a significant industry-wide challenge Vestas is actively working to solve at commercial scale.
Vestas offers three core digital platforms. VestasOnline provides remote self-service turbine management, including service scheduling, service order reports (archived back to 2017), and the Blade Asset Management application for cross-brand blade condition monitoring. Scipher® is an industrial energy analytics platform that applies machine learning to the industry's largest operational dataset for actionable performance insights. VestasDeveloper is a Customer Data Integration Platform offering standardized APIs for integrating Vestas operations data into operators' own systems. ShopVestas is a 24/7 e-commerce platform listing 100,000+ spare parts and consumables across all turbine platforms and brands.
Vestas' Plant & Energy Solutions division does offer hybrid power plant capabilities combining wind, solar PV, and battery storage under a single control strategy. The Kennedy Energy Park in Australia is a reference project with 43.2 MW of Vestas wind turbines, 15 MW of solar PV, and 2 MW/4 MWh of battery storage, all under a 15-year AOM 4000 service agreement covering the full plant. However, Vestas does not manufacture solar panels or batteries — it integrates third-party components. For developers seeking a single-vendor, multi-technology OEM, this is a limitation compared to companies like Siemens Energy or GE Vernova that produce hardware across multiple generation technologies.
Vestas has been ranked the #1 most sustainable energy solutions company and #3 overall by Corporate Knights Global 100 for four consecutive years. EnVentus turbines emit 5.6–7.1 gCO₂e/kWh (versus approximately 1,002 gCO₂e/kWh for coal), become energy-neutral within 5.9–7.4 months of operation, and produce 32–41 times more energy over their lifetime than they consume. The company has committed to zero-waste turbines by 2040, with a 100% recyclable rotor by 2030. Vestas also offers low-emission steel tower options and publishes detailed lifecycle assessments verified by independent organizations. The company reported EUR 18.8 billion in revenue for 2025 with a 5.7% EBIT margin.
