SHAP-based feature ranking identified temperature and humidity as the most influential drivers of electricity-demand. The k-means clustering revealed three distinct groups/clusters, which reflect the climatic-consumption scenarios. The ensemble learning (RF and XGBoost) exhibited the lowest training-error.
