Electric vehicles and DSOs : working towards a joint future?

Abstract

The discussion on the network integration of electric vehicles is reminiscent of that on the integration of intermittent renewables, such as solar and wind energy and other alternative sources, about ten years ago. Whenever radically new technologies gain traction, they may have a significant impact on the existing system. But whereas ten years ago any calls for early impact assessment were met with scepticism, the sector now seems to have learned its lesson. Although demand for electric vehicles is growing, mainstream adoption is still far from being achieved. Nevertheless, DSOs and regulators are already seriously considering the challenges ahead. After all, the mobility landscape may change faster than currently expected and they feel it is better to be prepared than to be caught out. On 12 December 2019, the DSO Chair organised a workshop to discuss challenges and issues related to the demand-side integration of electric vehicles into the electricity distribution network. Prior to the workshop we interviewed key stakeholders and participants, as well as several experts, to gather background information as a basis for discussion. This white paper provides a round-up of the findings and insights as well as suggesting areas for further exploration.
