This paper aims to provide a thorough guide on how to analyze complex energy demand forecasting models with Shapley Additive exPlanations (SHAP) in order to build trust in their predictions and understand the model and SHAP limitations based on selected real-world use case. There are only few examples described in the literature in energy industry and they present very basic usage. This study fills the gap for the class of energy (heat, electric, gas) demand predicting models by showing step by step, top-down analysis of state-of-the-art, deep neural network model predicting total heat demand (hot water and room heating) in Warsaw District Heating Network – the largest district heating network in EU. The paper shows how SHAP can be successfully used on demand forecasting models to provide practical, easily interpretable insights on inner workings of these models which can be used to assess their reliability and plan further development. • Predictions of deep neural network models forecasting energy demand can be explained. • SHAP can be successfully used to analyze deep ANN with multiple inputs (>100). • Step by step guide on how to analyze energy demand model with SHAP is provided. • Relationships identified by ANN forecasting heat demand agree with expert knowledge. • Trust in predictions of black-box models can be build by analyzing with SHAP.
