Electric vehicles are expected to take over our roads in the coming decade, but can our electricity infrastructure cope with the additional demands they will place on it?

Transport is expected to become electrified in coming decades, bringing new benefits, challenges and opportunities. As electric vehicles (EVs) displace internal combustion engine vehicles, a number of benefits are likely to follow: reduced costs for vehicle operation and maintenance, reduced greenhouse gas emissions, and use of the substantial battery storage present in EVs to compensate for variability in energy supply and demand.

However, there have also been some widespread concerns that are perhaps contributing to the slow uptake of electric vehicles in countries such as Australia. These include the up-front vehicle cost, a lower driving range before recharging is required, and the availability of fast-charging infrastructure. For the electricity distributors there are also questions about the impact of electric vehicles on the electricity grid.

We set out to investigate the validity of most of the latter concerns, and to quantify the potential benefits of transport...
