As part of the Energy Strategy 2050, electricity meters at end consumers are being replaced with smart meters. However, their introduction does not per se result in energy savings, as current studies imply. Research suggests that target-group-specific behavioral change interventions can increase the potential of smart meters on energy savings. Yet, there is a lack of experimental studies that test the use of target-group-specific interventions in the field and allow for causal inference. This project uses the smart meter rollout of ewz as an ideal environment for field experiments and investigates (1) which interventions (incentives and information) motivate first-time use of the smart meter platform, (2) which target group segments can be formed, and (3) the effectiveness of target-group-specific interventions to promote sustainable energy consumption. The findings can be applied in the development of new target-group- specific energy policy instruments.
