The peak power demand and energy demand imposed by the deployment of electric vehicles are examined for the city ofPerth, Western Australia. Penetrations of up to 100% of the lightvehicle fleet, 800,000 vehicles, are considered by allocatingvehicles to zone substations in proportion to the number ofcustomer connections and then assessing the loading impacts inthe sub-transmission system, bulk supply terminal substationsand transmission system. Recommendations made as to thecontrolled charging regimes that can be employed. The impactsare assessed over a ten year planning horizon.
