Users’ Willingness to Participate in V2G – A Comparison Between German and UK Households

Vehicle-to-grid (V2G) enables a smoother integration of large numbers of electric vehicles (EVs) into the electricity system by maximizing the flexibility potential. As such, EVs might emerge as new payers in the electricity market opening up new business models. Whether EVs will be available for these business models hinges on the user's willingness to participate and the monetary gains they anticipate. To shed light on users’ motivations and requirements, we conducted a survey among German and UK households with N=1100. Results indicate that people are willing to participate in V2G, but compensation requirements are high in both countries (mean values for Germany= 67.54 €/month, UK= 60.96 €/month). Additionally, regression analysis reveals that psychographic characteristics positively predict the willingness to participate, while contextual factors play a subordinate role. Our results are important as they shed light on the conditions that must be met to support V2G uptake from the user's perspective.
