Impact of implementation of ERS on the German and Swedish electricity system

The climate benefit from an introduction of Electric Road Systems (ERS) and an increase in the share of electromobility will be determined by the impact on the electricity generation which will be different between countries, depending on the characteristics of the electricity system such as the conditions for renewable electricity. An electrification of the transport sector through electric vehicles (EVs) with static charging and/or ERS introduces a new demand to the electricity system, and hence, will create new load profiles depending on the time of consumption and the amount of electricity used in EVs. Depending on electrification strategy, this new demand may introduce a potential for EVs to provide demand-side management to the power grid. The overall aim of this work is to apply two different electricity systems models to investigate how an electrification of the transport sector could impact the Swedish and German electricity system with respect to energy and power.
