How do we validate that our solutions have the desired effect? To prove the effectiveness of our upgrade solutions we use the simple, but robust and widely accepted side-by-side method for performance validation. The method involves selecting pairs of neighboring turbines based on site terrain and service history with some turbines being upgraded and others left as-is serving as reference units. By analyzing time-synchronized SCADA-data, we compare the power production before and after the installation of blade add-ons. By analyzing the power signal only, the known uncertainties related to wind speed measurements are cancelled out resulting in as low as +/-0,5% uncertainty when using the side-by-side method. To ensure a reliable statistical analysis, we typically require 6-12 months data before and after installation of the upgrade. Our more than 1400 installations worldwide are field proven delivering high performance throughout the turbine’s lifetime. Additionally, we provide comprehensive documentation at every stage of the project, ensuring our customers have confidence and certainty in their business case. #renewableenergy #windturbine #blades #aerodynamic #performance

𝗗𝗶𝗱 𝘆𝗼𝘂 𝗸𝗻𝗼𝘄 𝗣𝗼𝘄𝗲𝗿𝗖𝘂𝗿𝘃𝗲 𝗩𝗼𝗿𝘁𝗲𝘅 𝗚𝗲𝗻𝗲𝗿𝗮𝘁𝗼𝗿𝘀 (𝗩𝗚𝘀) 𝗮𝗿𝗲 𝗶𝗻𝘀𝘁𝗮𝗹𝗹𝗲𝗱 𝗼𝗻 𝗯𝗼𝘁𝗵 𝘁𝗵𝗲 𝗶𝗻𝗯𝗼𝗮𝗿𝗱 𝗮𝗻𝗱 𝗼𝘂𝘁𝗯𝗼𝗮𝗿𝗱 𝗿𝗲𝗴𝗶𝗼𝗻𝘀 𝗼𝗳 𝘁𝗵𝗲 𝗯𝗹𝗮𝗱𝗲? 👀 When we assess a blade’s upgrade potential, we focus on both the inner and outer regions to deliver maximum aerodynamic performance: 𝗜𝗻𝗯𝗼𝗮𝗿𝗱 𝗥𝗲𝗴𝗶𝗼𝗻: The aerofoils used in this part of the blade are thick due to structural considerations, leading to significant flow separation, known as stall. This is common across all blades as they transition from a circular load-carrying structure near the root to highly efficient aerofoils toward the tip. To address this, we install VGs to keep the airflow attached to the blade surface for longer. This reduces stall, increases lift, and boosts power production. 𝗢𝘂𝘁𝗯𝗼𝗮𝗿𝗱 𝗥𝗲𝗴𝗶𝗼𝗻: Here, the challenge is recovering energy lost due to leading edge contamination and erosion. Erosion disrupts the airflow over the blade, reducing lift and increasing drag, which impacts turbine performance. Our VGs are specifically designed to re-energize the airflow, and thereby mitigate separation, and recover lost energy, ensuring optimal efficiency in this critical region. With over 1400+ turbines worldwide equipped with PowerCurve solutions, we’ve seen that every blade has upgrade potential. We don’t rely on one-size-fits-all solutions - each blade is analyzed, and a bespoke solution is designed to optimize performance for the entire blade length. #windturbines #blades #aerodynamic #renewableenergy #optimization

Did you know that turbines located in the same site can have different AEP losses? Turbines located in the same wind park would be expected to have the same AEP losses as they are exposed to the same weather conditions. We have used AeroVista to analyse this, and despite proactive maintenance and similar site conditions, turbine AEP losses vary within sites. The spread in AEP loss highlights the need to assess blade damage at the turbine level rather than relying on site-wide metrics. AeroVista uses real world data from drone inspections combined with high fidelity blade models to calculate turbine AEP loss – enabling operators to identify best- and worst performing turbines. #Windturbine #blades #aerodynamic #droneinspection #renewableenergy

86% of Aero-Significant Damages Occur in the Outer 30% of Wind Turbine Blades Using AeroVista, we analyzed a dataset of 1,500 turbines spanning 8 different models of varying ages across multiple wind farms. The results confirmed what we expected: the majority of aerodynamically significant damages—and blade damages in general—occur in the outer part of the blade. This is no coincidence. Blade damage initiation, propagation, and severity are closely tied to local velocity, as impacts from rain and other airborne particles are a primary cause. Our findings show that over 86% of all blade damages are concentrated in the outer 30% of the blade span. This insight highlights the importance of focusing inspections and mitigation efforts on this critical area. Targeted attention here can help recover lost AEP and ensure turbines operate at their best. 👉 Learn more about AeroVista here: https://lnkd.in/ea_BfDsb #windturbines #performance #operations #blades #aerodynamics

Stop noise curtailment and let your wind turbines produce more power 💪🔈❌ As turbines have increased in size, noise has also increased due to higher tip speeds. A typical mitigation approach to this problem is to run the turbine in a low noise mode, thus producing less energy. Curtailing power production is a blunt tool for addressing the problem of turbine noise and does nothing to address the source of the problem. By installing PowerCurve’s noise reduction solutions the problem is addressed at its source – the trailing edges of aerofoils - allowing turbines to escape noise reduced operation modes and maintain the extended AEP. PowerCurve Serrations are a field-proven and validated technology and deliver up to 3,5 dB noise reduction. The technology can be deployed pre- and post-turbine installation. 👉 Learn more: https://lnkd.in/e4kRT-fQ

Understanding Lift and Drag: The Keys to Wind Turbine Blade Performance Ever wondered how wind turbine blades convert wind into energy? It all comes down to mastering the balance between lift and drag—two aerodynamic forces that determine how effectively a turbine blade captures energy. 1. Lift is the driving force behind power generation. As wind flows over the airfoil-shaped surfaces of the blades, lift is created, converting wind energy into the rotational energy that powers the turbine. Carefully engineered blade shapes ensure optimal lift distribution, maximizing energy production and efficiency. 2. Drag, however, works against the turbine by resisting motion. This aerodynamic resistance disrupts efficiency, reducing the amount of energy the turbine can convert. Minimizing drag is crucial to ensure that more of the wind’s energy is captured and transformed into useful mechanical power. By precisely balancing lift and drag, wind turbine designers optimize blade performance, allowing turbines to extract the maximum energy from the wind. Every aspect of the blade—from its curvature to its surface finish—is meticulously designed to enhance this balance, ensuring reliable, efficient energy production. The better a turbine blade manages lift and drag, the more electricity it produces—and the greater its contribution to clean energy. #WindTurbine #BladeOptimization #LiftDrag #RenewableEnergy #Aerodynamics

Did you know that ice on wind turbine blades reduces performance?👀❄ Wind turbines in cold climates or regions with frequent winter weather often experience icing on the blades. When ice accumulates, it disrupts airflow over the blade surface, diminishing aerodynamic efficiency and leading to reduced power output. There are effective ways to mitigate this loss in performance. For turbines affected by light icing or frost, Vortex Generators (VGs) can help recover lost energy by re-energizing airflow and improving aerodynamics, even in icy conditions. 👉 Read more: https://lnkd.in/eUR_gcFE
