Energy Yield Assessment (EYA)
From wind to watts
Reliable energy yield assessment with windPRO
Accurate energy yield assessments are the cornerstone of any wind project’s technical and financial success.
Overestimating output leads to disappointed investors and missed revenue targets; underestimating it can stall promising projects. Developers must estimate real-world turbine production using site-specific wind data, terrain, wake effects, and system losses — and deliver it all in a format that banks and investors trust.

Why EYA matters
Consider these risks
Inaccurate wind speed modeling can lead to significant yield miscalculations and revenue loss.
Terrain complexity, forest roughness, and nearby obstacles can distort wind flow if not properly accounted for.
Lack of an understanding of the long-term climate can result in misleading short-term measurement interpretations.
Poor wake modelling can lead to larger discrepancies between projections and actual production.
Investors and banks require transparent and validated models to secure project financing.
Solve these challenges with windPRO
windPRO features for Energy Yield Assesement
Import time series data from various sources and formats to build a detailed, location-specific wind climate model backed by real-world data.
Detect and fix issues in your data, fill missing values, and cross-check different sensors to ensure accuracy and consistency in your analysis.
Easily combine and compare data from reanalysis sources like ERA5, MERRA2, and CERRA with onsite measurements from met masts, LiDAR, and SoDAR. This gives you a complete picture of wind conditions using all available information.
Break down wind patterns by month and direction to better plan turbine types, placement, and maintenance strategies that align with seasonal variations.
Extend short-term onsite measurements using long-term reference datasets. Apply industry-standard regression techniques to correct and adjust your data for more long-term predictions.
Simulate wind flow across complex landscapes using WAsP and fast, high-resolution CFD calculations. Estimate wind resources even in hilly or forested areas.
Create clear visuals like wind speed maps and wake interactions. These are great for internal planning and communicating with stakeholders or regulators.
Model how turbines affect each other through wake effects. Analyze different layout scenarios to reduce energy losses and optimize the farm's overall performance.
Use the OPTIMIZER to automatically find the best turbine placements that minimize losses and maximize energy yield — all while saving time in the design process.
Quantify all expected system losses and generate P50, P75, and P90 scenarios. This gives you reliable, finance-ready reports for investment and risk assessment.
Easily compare wind potential, layout options, and constraints across multiple locations. Identify the most promising site for development with confidence.
