Abstract
Abstract We investigate the impact of providing households with disaggregate consumption feedback and develop a framework to assess its welfare implications. In the context of smart metering, we find that the provision of appliance-level feedback causes an energy conservation effect of 5% relative to a group receiving standard (aggregate) feedback. Hence, a smart meter rollout will be substantially more effective if appliance-level feedback is provided. We also show that the current regulatory approach to assess consumer surplus overestimates the welfare gains from smart meter feedback.
