Abstract
Norway is currently the largest market in the world for electric vehicles compared to the total number of vehicles sold, and there is also a political goal in Norway to stop the sale of new conventional cars 1 by 2025. Changing to non-emission transport can result in approx. 1.5 mill. private electric vehicles in 2030, resulting in an energy need of 4 TWh, which represents an increase of 3% of the Norwegian electricity consumption. The increased number of electric vehicles will not be an energy problem, but it can be a capacity related problem in the distribution grid if all households are charging at the same time – in addition to their usual consumption of electricity. This paper presents results from a research project evaluating the consequences of the increasing share of electric vehicles and the potential for demand response and flexibility in charging. Results are based on a survey performed among households with electric vehicles and meter data of the energy consumption from charging of a selection of the most common electrical vehicles in Norway.
