Active Output Management®

Vestas | Active Output Management

AOM. Your Power - Our Commitment

Our job really begins once your wind power plant is installed and in operation. Our philosophy is that making the most of your plant is about more than just engineering and logistics. It’s about working together – creating solutions that revolve around your specific needs and your expectations. That’s why we offer our unique AOM programme, based on three decades of industry experience. With Vestas AOM you are supported by a proven service partner –working in collaboration with you to identify, allocate, and properly manage risks, and ensure peak performance from your plant.

Vestas is committed to the smooth running of your business - ensuring that you benefit from industry-leading performance, research, innovation, expert technical teams, and a global supply chain that is reliable, efficient and cost-effective. All of this is done with one aim in mind: to offer you predictability, and to strengthen the certainty of your business case.

Maintenance Packages

Vestas | Service Packages

Wind turbines need to be continually serviced to perform consistently at their best. Harsh weather conditions over the course of a turbine’s typical 20-year service life can reduce the overall performance of a site, resulting in a loss of earnings and a poor return on your investment.

Our Active Output Management® service programme, or AOM for short, ensures the highest possible output at all times, so your return on investment is achievable and more secure.


    AOM 5000

    Minimise your lost production

    AOM 5000 is our most comprehensive service package and includes everything necessary to maximise output, plus incentives such as an energy-based availability guarantee that aligns service and maintenance operations with low wind periods.

    The AOM 5000 service package aims to minimise lost production for up to 10 years (with an option to renew for two additional five-year periods), together with energy-based guarantees of up to 97% (subject to site evaluation). These high expectations are formalised through liquidated damages and bonus clauses in the contract.

    AOM 4000

    Maximise uptime and performance

    AOM 4000 is a comprehensive service package including all necessary main components and material to maximise uptime and performance.

    The service contract covers periods up to 10 years, with an option to renew for two additional five-year periods, suitable for customers who want the traditional time-based availability guarantee of up to 97%. These high expectations are formalised through liquidated damages and bonus clauses in the contract.

    AOM 1-3000

    Risk sharing and flexible solutions

    AOM 3000 – Share the risk

    For a comprehensive field service package that includes consumables and spare parts, AOM 3000 represents the value option for the risk-averse customer. It takes the benefits of the AOM 2000 agreement to the next level by including both fixed-price scheduled and unscheduled maintenance, maximising the reliability of your turbines. Only main components are excluded from the package, so by shifting the risk of repairs to Vestas, business case certainty is increased.

    AOM 2000 – Reduce the risk of downtime

    The AOM 2000 builds on the benefits of AOM 1000, with the added advantage of a fixed-price preventive maintenance programme. You gain the reassurance of knowing that your turbines will be well maintained, but without the commitment – or cost - of a more comprehensive service package.

    With AOM 2000, turbine performance is sustained through regular maintenance, with the option of additional maintenance items.

    AOM 1000 - For maximum flexibility

    AOM 1000 provides you with maximum flexibility for maintaining and servicing your windfarm. You buy services purely on a pay-as-you-go basis, ensuring you never spend any more than necessary. We provide troubleshooting and corrective maintenance with the benefits of OEM technicians, parts and tools.

    Parts & Repair

    Vestas | Spare parts

    Global supply chain, local presence
    Vestas distributes more than 500,000 parts per year and co-operate with more than 1,000 suppliers globally, to make sure that your costs are minimised. With 19 warehouses around the globe, and more than 19,000 parts on stock, we ensure that your turbines return to production in the shortest time possible, independent on the type of part you may need.

    Care concepts for main components
    Major components are a root cause to unexpected O&M costs. That is why Vestas consistently develop preventive and corrective repair solutions for blades, generators, gearboxes and transformers. Vestas service technicians perform uptower repair solutions for major components in more than 50 countries, which is a result of our dedication to become a global leader in the parts and repair market. Preventive solutions, such as inspections, represent a cost- and time-efficient alternative to running the component to failure. By repairing the component before it breaks, you will achieve an improved lifetime of the component, while keeping your O&M costs under control. That is optimised performance.
