Aggregated impacts of electric vehicles on electricity distribution in New South Wales, Australia

One of the consequences of the widespread adoption of electric vehicles (EVs) will be an increase in demand for electric energy and an associated increase in loading on the electricity distribution grid. The data available on EV usage are still sparse, however useful information on the potential impact of EVs was derived from the New South Wales (NSW) Household Travel Survey (2014/15) to determine the increase in electricity demand as a function of time and location. It has been found that a large majority of all weekday vehicle trips could be provided using affordable EVs and that the resulting demand for electricity would increase by more than 10% in only 9 out of 35 local government areas (LGAs) in NSW. Furthermore, it was found that more than 50 MWh/day of electrical energy would be available for providing vehicle-to-grid (V2G) services in 46 out of 50 LGAs.
