Abstract
In this field experiment, we explore the potential of providing appliance-level feedback to correct households' misperceptions of energy intensities. We also develop a framework to investigate the impact of disaggregate feedback on consumer welfare and derive sufficient statistics to quantify it, thus providing a novel tool for regulatory impact analysis. The context of our study is the deployment of advanced metering infrastructure throughout the world, which involves multi-billion investments into so-called smart electricity meters.

Experimental Details

Interventions

Intervention(s)
We conduct a field experiment and provide electricity use feedback through a smartphone app. Participants in the experimental control group obtain aggregate feedback as traditionally provided by smart metering interventions. Participants in our first treatment group additionally receive information on their appliance-level electricity use. We also implement three further treatment groups that complement appliance-level feedback with incentives to encourage the conservation of energy. Participants in the second treatment group receive a bonus based on their absolute reduction in electricity use for a given appliance. In the third group, we inform participants how their electricity savings compare to the savings of other study households. In the fourth group, participants receive a bonus if their savings are high relative to the savings of others.
