Showcasing the value of Aerodynamic Upgrades As part of the PowerPlusTM product suite, Aerodynamic Upgrades improve the aerodynamic performance of the rotor blades, boosting annual energy production (AEP) by up to 2%. The technology consists of two add-ons, Vortex Generators and Gurney Flaps, 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. The technologies are well-established in the industry and have been widely accepted as a performance enhancement. However, to get a stronger understanding of the actual improvement in energy output, Vestas has carried out rigourous validation across a number of different sites. In this case study, you can read about the results of our validations, hear from a customer, and learn more about how the add-ons actually improve the aerodynamics.
