Abstract: The need for a more secure green power supply and a wiser grid expansion demands thorough analysis of the electrical energy demand growth and also of future installations of renewable energy sources. In the present study the increase of electricity demand for a city due to electric mobility penetration has been estimated. Consequently, the expansion of renewables is also examined as possible mitigation measure against grid stress. During the simulation process several scenarios are considered and different grid indexes are calculated and applied as metric factors. Simulation results indicate that the electric mobility brings almost up to 20% increase in the total electricity demand of the chosen urban area by 2050. Moreover, outcomes show that the higher penetration levels of wind energy in the renewable energy mix result in a more reliable power supply by reducing great variations in the grid exchange and by leading to higher degrees of self-sufficiency.
