1、Home EV charging and the grid:Impact to 2030 in AustraliaEdition 2.1,December 2024 Prepared by Michael Shaughnessy1Home EV charging and the grid:Impact to 2030 in AustraliaExecutive summary1 https:/www.aer.gov.au/industry/registers/charts/seasonal-peak-demand-nem2 https:/.au/grid-demand-records-smas

2、hed-as-w-a-becomes-hottest-place-on-planet/The potential for EVs to add load to the energy system at times of peak demand is a risk that many parties have interest in,particularly the energy network operators(DNSPs and TNSPs).A simple back of the envelope exercise is sufficient to show that a relati

3、vely small level of EV transition has the potential to cause serious problems for networks if the majority of EV charging occurs when people return home from work in the eveningWork of this nature has been done by CSIRO and Melbourne University among others,generally based on sample data from EV cha

4、rging trial programs in non-Australian jurisdictions.These studies estimate that the impact on the grid during peak times could be as much as 2 kW per vehicle.The CSIRO work has been used to inform AEMOs energy system planning documents and are being relied upon in the formation of government policy

5、.As a contribution to this ongoing discussion,the EVC has drawn together real-world data on consumer EV charging behaviour in Australia.From multiple independent pieces of work,it is apparent that Australian consumers with EVs are currently choosing to self-manage their EV charging to a significant

6、degree.Most at-home EV charging currently takes place either in the middle of the night or during the middle of the day,with relatively little charging occurring during peak periods.Contribution per EV to evening grid peak demand appears to be on the order of 250W.Assuming this behavior continues an
