Persistence of the effects of providing feedback alongside smart metering devices on household electricity demand

Using large-sample high temporal resolution data from a smart metering field trial, we econometrically estimate the effects of providing feedback in addition to smart metering devices. We compare consumption levels and patterns between a pilot group that received feedback in addition to smart metering devices and a control group with only smart metering devices. We investigate, in particular, the persistence of the effects and whether the effects differ between periods of high and low household occupancy, i.e. between morning and evening periods, and between weekdays and weekend days. The findings show that feedback is effective, leading to about 5% electricity consumption reduction that is persistent over an eleven month period. Furthermore, our results show that this reduction affects both low and high occupancy periods, suggesting that feedback is associated with rather permanent changes in habitual behavior and/or investments in energy-efficient technologies. - Highlights: • Analysis of feedback on household electricity use relying on high resolution data. • Average feedback corresponds with savings of around 5% on weekdays and weekends. • Effects of feedback are persistent during the eleven month field trial. • In percentage terms, feedback effects are rather stable over the hours of the day.
