Vestas Sound Power Optimisation Combining siting methods, sound mitigation strategy, and technical solutions to maximise energy production at specific sound power levels Sound Mitigation Strategy: Sound Optimised Mode and application variables can be applied individually or in combination to meet site specific conditions and requirements. Application variables include, time of day, week day, date range, wind speed, and wind direction. Example • Sound Optimised Mode: 98 Db(A) • Time: From 20:00 to 06:00, Workdays only, from 3 April to 31 October • Wind speed: From 10.5 to 17.6 m/s • Wind direction: From 28 to 136 degrees Siting Methods Vestas’ industry-leading siting methods is the first step in sound power optimisation. In order to optimise layouts according to sound power levels and requirements, Vestas Wind and Site engineers consistently deploy Vestas’ DNV-certified siting process and advanced tools, including Computational Fluid Dynamics (CFD) modelling. Operational strategies for sound power levels Vestas’ wind turbines benefit from the availability of multiple Sound Optimised Modes configured to meet known requirements in relevant markets. These modes can be combined with application variables to create a tailored sound mitigation strategy to meet unique site specific conditions. Sound power emission is controlled by optimising the operational parameters of the turbine. Optimal performance is achieved by only deviating from maximum energy production when needed, due to a specific time, wind speed or

Impact of Serrated Trailing Edge technology Without STEs Sound Power Level dB(A) With STEs Vestas’ Serrated Trailing Edge (STE) technology mixes the airflows, securing optimal airflow around the blade profile, resulting in a reduction of sound power level by up to 3 dB(A). Example based on V136-3.45 MW® with 3.6 MW Power Optimised Mode. Actual performance depends on site specific conditions. Serrated Trailing Edge technology is a standard option for all Vestas 4 MW platform turbines. Advanced technology lowering base sound power levels The dominant source of sound emission by wind turbines...
