    Turbine Options

    Vestas | Turbine Options

    An option is an extra feature that can be added to the turbine to suit a project’s specific needs. By adding options to the standard turbine, we can enhance the performance of the wind power project – and the business case certainty of the investment. Here are some of our options, although their availability will differ from country to country and from turbine to turbine.


      Fire Suppression System

      Vestas | Fire Suppression System


      The Vestas turbines can be equipped with a system of smoke sensors as a first line of defense against the development of a fire. If one of the sensors is activated, the turbine will shut down. As a second line of defense, a temperature-activated Fire Suppression System can be optionally installed to automatically extinguish a fire.

      The Fire Suppression System’s layout targets the main risk areas and is optimised to fit the respective turbine types.

      The Fire Suppression System operates independently from the turbine and does not require a source of power.

      The Fire Suppression System is available for all variants of the 3 MW platform.

      Shadow Detection System

      Vestas | Shadow Detection System

      Shadow flicker is the effect caused by the sun shining through the rotating blades of a turbine. Shadow flicker is one of the drawbacks of locating a wind farm near houses. In fact, shadow flicker can sometimes dictate whether planning permission is granted or not.

      You can avoid shadow flicker by equipping your turbines with the Vestas Shadow Detection System. The system is integrated with the control system of the turbine. If the unit registers shadow flicker beyond a certain threshold, it pauses the blades to avoid the strobing effect on nearby properties.

      Shadow controllers are uniquely configured for each turbine. They are programmed with the locations of neighbouring properties, as well as timetables indicating when shadow flicker must be avoided.

      The Vestas Shadow Detection System is compatible with all Vestas turbine models.

      Increased Cut-In Wind Speed

      Vestas | Increased Cut-In Wind Speed

      Increased Cut-In Wind Speed is a system intended to prevent bat and bird blade strikes. The system controls the turbine operational cut-in wind speed based on predefined parameters around the turbine, which includes bat and bird migration patterns.

      Increased Cut-In Wind Speed is compatible with all Vestas turbine models.

      View the Increased Cut-In Wind Speed brochure

      Load and Power Modes

      Vestas | Load and Power Modes


      Wind sites are classified according to certain climactic characteristics (e.g. IEC IA, IEC IIA and IEC IIIA) but in the real world few sites fit these definitions perfectly. To extract the maximum potential wind power from a site, turbines must be configured for uneven wind conditions, turbulence levels, varied topography and air density.

      Vestas Load and Power Modes is an advanced wind sector management system. It adjusts turbine operation to extract the maximum potential energy from a given site according to the conditions forecasted during the siting process.

      Vestas Load and Power Modes is designed to increase the flexibility of individual turbines, exploit optimum power curves of each turbine within your site, maximise energy production and protect your return on investment (ROI).

      Condition Monitoring System

      Vestas | Condition Monitoring System

      This condition monitoring system analyses how your wind turbine is performing via a series of sensors. You’ll know early on if something isn’t performing as expected, and you can service and maintain the wind turbine before a problem becomes crucial and causes prolonged down time. That way you’ll reduce unscheduled maintenance, improve availability, reduce repair costs, plan repair logistics more efficiently, and add value over the long-term.

      The Condition Monitoring System is is compatible with all Vestas turbine models.

      Aviation Markings

      Vestas | Aviation Markings

      Aviation markings on the blades

      We offer contrasting colour stripes on blades, which are colour-coded by country, in order to make our turbines more visible for aircraft.

      Aviation lights

      Vestas offers a variety of aviation light solutions and related products to meet both international and national requirements for aviation marking of wind turbines.

      The aviation lights on both the nacelle and tower are visible 360° around the turbine. By adding visibility sensors, light intensity can be reduced in clear weather conditions. In case further reduction is needed the OCAS™ radar based solution only activates the lights when an aircraft is operating in the immediate vicinity of the wind farm. This reduces the visual impact to a minimum.

      The aviation lights are available in different configuration with variable colours (red or white), flash rates and intensities. As a standard, two lights are located on the top of the nacelle and, when required, four lights around the same radius on the tower to ensure 360° visibility.

      View the Aviation lights brochure

      Copper Caps

      Vestas | Copper Caps

      The powerful energy discharge during lightning strikes can cause severe damage to blades, and in worst cases lead to structural destruction. Such damage results in expensive repairs or replacement and lost energy production while damaged blades are being repaired.

      Vestas' improved lightning protection will significantly reduce this risk of damage due to lightning strikes. The improvement consists of a copper cap for each blade tip. The copper cap is made of a thin plate, which makes the entire tip surface conductive and at the same time shields the tip to control the electrical field enhancement.


      • Eliminated or significantly reduced costs for blade replacement or maintenance
      • Reduced turbine downtime caused by damaged blades and replacement or repair
      • Reduced insurance costs

      Yaw Power Backup

      Vestas | Yaw Power Back Up

      The Yaw Power Backup system is a combination of sensors and software to control the turbine above standard cut-out speeds. It ensures that the nacelle and blade assembly can continue to yaw accurately in winds of up to 70 m/s.

      The functionality consists of a special operational mode to ensure continuous yawing for turbines in areas where the risk of extreme wind events exists.  Connection of an external power back up system to power the yaw system during grid outage is optional.

      View the Yaw Power Backup brochure

      Large Diameter Steel Tower (LDST)


      Reaching higher in low wind

      Vestas’ proprietary Large Diameter Steel Tower (LDST) technology combines proven steel construction with an innovative design to deliver strength and height. Easy transportation and quick installation contribute to excellent cost of energy.

      LDST is a simple, yet highly efficient way to harvest wind resources at low-wind sites. Higher hub heights increase the force exerted by the wind on the Tower structure, which typically would require usage of thicker steel plates. Instead, LDST technology adds strength by increasing the diameter of the bottom sections without adding extra steel, reducing production costs, and ensuring at least 99 percent recyclability. Reaching higher with the LDST technology can result in up to 20 percent* higher Annual Energy Production (AEP).

      View the Vestas' LDST brochure

      High Wind Operation 

      High Wind Operation (HWO)

      Vestas’ High Wind Operation (HWO) is an intelligent control feature that allows the turbine to continue operating beyond standard cut-out wind speeds. HWO gradually reduces energy production following a derating profile to enable extended wind turbine operation. The result is improved output stability, energy production, and reliability.

      HWO can be applied to all Vestas turbine models operating with the VMP Global™ software platform.

      View the Vestas HWO Brochure
