victorian electric vehicle trial mid-term report - Department of Transport

An example of this was theDepartment’s own experiencewith its property at 121 ExhibitionSt, Melbourne. The Departmentleases levels 5 to 16 of the 36 levelbuilding, along with a portion of theunderground car-parking. As part ofthe trial, the Department requestedpermission to install an electricvehicle charging solution. The buildingmanager proposed a charging circuitbe run from the lowest point ofmetered electrical supply billed tothe Department on building level 5 tothe nearest underground car-park onbasement level 3. This was determinedto be cost-prohibitive, and despiteextensive negotiations to obtain a costeffectivealternative the proposal had tobe aborted.A charging outlet was instead installedin a nearby property also tenantedby the Department, using an unusedelectricity billing meter thatwas one level away from the nearestDepartment parking location. Thisinstallation cost $4,500, which was stillsignificantly higher than the averagefor a commercial property but muchlower than what was expected underthe alternate arrangement.5.3.2 How is charginginfrastructure installed forcorporate applications?Charging infrastructure for corporateapplications is installed by electricalcontractors. Charging circuits can beinstalled by in-house contractors, evenif this is often done by the chargingservice provider during installationof the dedicated electric vehiclecharging outlets. From the time whencommitment to establish EV chargingcapability is made, the averageleadtime to commissioning/handoveris around 10 weeks.Installation of electric vehiclecharging infrastructure for corporateapplications is greatly complicated byinternal approval requirements, alongwith the likely involvement of a thirdand sometimes fourth party in theproperty management and ownership.As a result, the average leadtime forinstallation of a corporate chargingsolution is around 70 days, whichis twice as long as for a homecharging solution.The general process for the installationof charging infrastructure for corporateapplications can be seen in Figure 40.AVERAGE / MEDIAN LEADTIME = 73 / 59 DAYSContractnegotiationSite worksplanningSite worksHandoverOperation• Explain deed• Q&A• In-principleagreement• Legal• Notifysub-contractor• Site survey• Report / quote• Signage• Scheduling• Site prep• Site works• Test andcommission• Demonstration • Paymentfor works• Staff training• Reporting• Transition• Sign-off• Works approval• Install signage• Consultation• Ground-markingFigure 40.
