PowerPlus®

As wind technology matures, turbines already in operation can be upgraded to yield more energy and thereby improve an existing wind park business case.

Improvements of the production efficiency of a wind power plant can be carried out through site-specific optimisation of operational parameters, implementation of intelligent software algorithms, and enhanced aerodynamics add-ons. All designed to make your turbine work smarter and harder. 

Vestas PowerPlus® can boost your annual energy production by up to 5% a year at virtually no risk. Our DNV-GL-certified siting process ensures that design life is not impacted, and with our performance guarantee and flexible financing options there is nothing in the way of your increased profits. 

PowerPlus® covers a range of upgrade possibilities that can be combined or installed independently, counting Aerodynamics Upgrades, Extended Cut Out, Power Performance Optimisation and Power Uprate.

Aerodynamic Upgrades

Improved blade efficiency

Aerodynamic Upgrades improve the aerodynamic performance of the rotor blades, boosting annual energy production (AEP) by up to 2%. Aerodynamic Upgrades are available for a range of Vestas platforms, as well as an extensive list of multibrand turbines.

The technology consists of Vortex Generators, which aid lift creation around the blades. This translates into a better aerodynamic performance during the turbine’s partial load operation. The AEP improvement is therefore captured on the slope of the power curve, when the turbine operates below rated power.

To know more about how Aerodynamic Upgrades can improve your business case, check out our case study featuring ENGIE Deutschland and our whitepaper, which goes into depth with the technology.


Extended Cut Out

Reap the benefits of high wind speeds

Vestas has developed Extended Cut Out, which allows turbines to operate beyond their original cut out speeds to capture the full potential of strong winds.

By increasing the cut out wind speed, Extended Cut Out can generally deliver an Annual Energy Production improvement of up to 3%, and even up to 5-7% at sites with very advantageous climatic conditions.

Read more about the results we have already delivered for other wind parks in our case study, or download our product sheet for a quick overview of the upgrade.

Power Performance Optimisation

Smarter operation with intelligent algorithms

To help turbine owners uncover and realise the uncaptured energy, Vestas has developed a range of smart algorithms to help the turbine make better decisions. Improved measurements of wind speed, wind direction, and optimal yaw alignment enable theturbine to act smarter and thereby become more effective.

Moreover, our algorithmic features allow for smarter use of power boosts as well as allowing the turbine to exploit low air-density climatic conditions to operate in high winds.

Power Uprate

Increase nominal power for a higher yield

Power Uprate is designed to increase the nominal power of your turbine, allowing you to use its full capacity.  An increased annual energy production of up to 4% can be achieved, proving an opportunity to significantly improve the performance of your fleet.


A site-specific analysis, using proprietary tools and certified processes, is always conducted to assess how the rated power of your turbine can be increased to maximise output, without affecting the original design.

    Case study

    Aerodynamic Upgrades


    Read a case study on Aerodynamic Upgrades, a PowerPlus
    ®  feature that includes two blade add-ons to improve the aerodynamic conditions over the root section of the blade. Doing so will increase wind capture, positively impacting AEP by up to 2%.

    ”Together with Vestas, we established a 
    common understanding of the gain potential. Vestas’ estimation tool convinced us, so we decided to upgrade all our V90-turbines to maximize our returns.”

    Rainer Röper
    Sr. Asset Manager, ENGIE Deutschland

    Case study

    Vestas PowerPlus' Aerodynamic Upgrades can improve AEP by up to 3%

    Rotor Upgrade

    Rotor Upgrade increases the rotor size of a turbine, expanding the swept area of the turbine blades. This enables greater wind capture and higher energy output up to 15%, depending on the turbine model and climatic conditions and other site-specific conditions.

    Blade technology innovations and insights into real-life, site-specific data allows for the retrofit upgrade of rotors. Vestas carefully analyses the turbine and site conditions before any upgrade is performed. A site-specific load-study ensures that both safety and design life are not affected.

    Rotor Upgrade is available for V90-1.8/2.0MW with more rotor upgrades applications in development.


    Multibrand Fleet Optimisation

    Our turbine upgrades and fleet optimisation solutions also cover a range of non-Vestas turbine technologies. These solutions fall under our multibrand services. With our fleet optimisation solutions for selected non-Vestas turbines, we constantly seek to improve the performance and efficiency of turbines outside our own turbine portfolio.


    We do this through our own research and development efforts, but also through strategic supplier agreements with trusted partners, which have shown outstanding innovation within wind technology. We choose our partners carefully to ensure the quality and standards are on par with Vestas’ own proven technology. Products offered through supplier partnerships are chosen based on their proven technology and validated results.


    Below you can find more information on our upgrade offerings for selected non-Vestas turbines, which ensure that existing turbines and wind parks achieve higher levels of performance.

    Yaw alignment

    To optimise yaw alignment on selected turbine types we provide a LiDAR system for yaw misalignment correction. The nacelle-mounted LiDAR measures wind direction and wind speed 80m in front of the wind turbine. It uses these measurements to optimise the yawing, providing increased energy production.


    The system is easily retrofitted on certain existing turbines with minimal interference and downtime. Since 2012, it has delivered proven performance, providing strong value for money for asset owners.

    Vortex generators

    Wind is by nature turbulent, which influences the performance of wind turbines. Vortex generators (VG) stabilise the wind flow around turbine blades, increasing energy yield, while reducing stall and noise emissions. On average vortex generators can increase annual energy production by more than 2 %.

    To improve the aerodynamic performance of selected non-Vestas turbines, Vestas provides a platform independent retro-fit technology, delivering  a cost effective and reliable aerodynamic upgrade solution for specific multibrand fleets.
