The energy and transport transition is leading to changes in the structure of electricity consumption that will have a fundamental impact on the requirements of the electricity distribution grids and cause a considerable need for grid expansion. E.ON SE and its grid operators addressed this at an early stage and commissioned Consentec back in 2017 to analyse the impact of the of e-mobility in particular on the of the Group’s four DSOs at the time. Specifically, changes in supply tasks and the resulting utilisation of the grids, the need for action due to emerging current- or voltage-driven grid bottlenecks as well as suitable conventional and innovative measures and their costs were examined on the basis of models.

These analyses were then extended to all nine DSOs of the E.ON Group and expanded in several stages to include the effects of the expansion of heat pumps and the expansion of renewable energy generation in the distribution grids as well as the increasing availability of consumption-side flexibility. In addition, adjustments to energy policy objectives such as the increase in renewable energy targets with the Easter Package 2022 were taken into account in further stages of the study.
