Use case: From Data to Clarity, A Complete View of Wind Farm Performance

Understanding how a wind farm truly performs requires more than a few summary metrics. Low-quality data, wind variability and complex turbine behaviour often blur the picture, making it difficult to see where energy is lost and why.

ExpertWind Insights was built to remove that uncertainty and provide a complete view of wind farm performance: from the overall energy yield to the root causes of underperformance in individual turbines.

1. Energy Yield: clarity on where energy is lost

Every analysis in Insights starts with a transparent energy-yield breakdown. Using SCADA data, the platform quantifies production and losses across all main categories: availability, curtailment, environmental factors, operation parameters and performance.

At both farm and turbine level, users can immediately see how each component contributes to the total energy balance. Insights clearly separates what comes from turbine behaviour and controllable factors from what results from external or environmental conditions. This distinction shows which losses can be recovered and which are inherent to site or external limitations.

By separating resource-driven effects from turbine-driven losses, operators can clearly understand whether lower production comes from external conditions or from issues within the turbines themselves. It turns the energy-yield breakdown into more than a report: it becomes a decision tool that shows where energy production can truly be improved.

2. Performance: accurate wind speeds and detailed diagnosis

Once losses are quantified, the next question is performance: how efficiently each turbine converts available wind into power?

Insights corrects wind-speed measurements through dedicated machine-learning models, trained for each turbine to ensure accuracy and consistency.

This correction step eliminates biases caused by sensor drift, transfer functions, faulty wind sensors and terrain effects, providing a reliable basis for power-curve evaluation. With these corrected wind speeds, Insights provides precise performance tracking over time and includes a Performance Diagnosis module that goes beyond simple deviation checks.

By combining turbine control laws with power-prediction models, the system can distinguish between expected behaviour and true underperformance, allowing users to identify the underlying cause rather than just the symptom.

3. Diagnostics: uncovering the root causes of underperformance

When performance issues appear, Insights provides specialised diagnostics to understand why. The platform analyses each region of the power curve with targeted methods to detect and quantify operational anomalies such as:

• Yaw misalignment (static or dynamic)
• North deviation
• Pitch and rotor-speed control
• Wind-sensor stability
• Turbine start-up
• Operation at nominal wind speeds

Each diagnostic is based on robust statistical and physical models, delivering results that are quantified, traceable and consistent. Operators can verify the origin of a loss, monitor its evolution and confirm the effectiveness of corrective actions, all within the same environment.

4. From results to action

Together, these results give operators and owners a complete view of their wind farm: a clear energy-yield summary, precise performance indicators and root-cause diagnostics that explain every deviation. Insights makes the path from detection to action straightforward.

The dashboard highlights new issues as soon as they appear in the data, and each diagnostic includes clear context, detailed interpretation and a recommended course of action.

You also have direct access to ExpertWind’s specialists through the interface, ensuring that complex cases can be analysed and resolved effectively.

ExpertWind Insights turns SCADA data into clarity, helping teams focus on what truly matters: understanding performance and improving it with confidence.
