Does (Co-)ownership in renewables matter for an electricity consumer's demand flexibility? Empirical evidence from Germany

Our results show a statistically significant effect of (co-)ownership of renewable energy production facilities on the willingness of citizens to adjust their consumption behaviour to match their electricity demand to production levels. However, this relation is complex: Only when consumer (co-)owners have the choice between self-consumption and sale of the surplus electricity production to the grid, a statistically significant difference is observed. Furthermore, positive effects on flexible consumption were only found for the usage of household appliances.
