The topic of energy has arrived at the center of society, and we are beginning to understand that we can change our behavior in a positive way. Data is of value to people because it enables them to develop a better understanding of themselves and the world around them. Data from fitness trackers, for example, help to benchmark one's own body/fitness and to derive motivation for behavioral changes from it. In order to be able to act and being incentivised, one needs a benchmark (score). For future flexible tarif models, an underlying metric is needed. In a decentralized, renewable energy system the customer plays an increasingly active role For exemple by using energy when renewable energy is abundantly available and by reducing one’s consumption when there is a scarcity To show customers their potential for improvement, we would like to introduce a simple score based on individual consumption patterns. This score ensures transparency and creates the basis for effective incentive measures.
