XAI for transparent wind turbine power curve models

Bigger ML models aren't always better: The paper found that larger machine learning models optimized purely for accuracy can learn physically implausible strategies—meaning they make correct predictions for the wrong reasons. This highlights a critical gap between test performance and real-world reliability in AI systems.

Explainability should guide model selection: Rather than treating transparency as an afterthought, the researchers argue that explainable AI (XAI) methods like Shapley values should be central to choosing which models to deploy. This ensures selected models not only perform well but also use strategies that make physical sense.

XAI enables practical maintenance benefits: The paper demonstrates how explanation methods can identify root causes of wind turbine underperformance, potentially reducing downtime and improving energy output. This shows XAI has concrete business value beyond compliance, making the case for responsible AI practices.

"Black box" ML poses risks in critical infrastructure: For applications like renewable energy systems—essential to the global energy transition—opaque models create barriers to adoption by operators and regulators who need to understand and trust system decisions.

Transparency and accuracy can be aligned: The research suggests that explainability methods help identify when models achieve good performance through unreliable mechanisms, enabling practitioners to find solutions that are both accurate and interpretable rather than forcing a choice between them.
