Overview
The WA State Government is investing in a greener public transport fleet with the purchase of 16 new EV buses to be based out of Elizabeth Quay Bus Station.
To provide charging for the new electric fleet additions, EV charging infrastructure will be added to the 18 existing bus layover bays, which currently provide short-term daytime parking for diesel vehicles.
Scope
Transperth (PTA) engaged Intellect Systems to review the existing electrical network and determine the ability to support EV charging infrastructure.
The review also required Intellect Systems to analyse the charging technology market and identify optimal systems.
Intellect Systems evaluated electrical load logging data, undertook site research and preliminary engineering to assist with the development of an Options and Feasibility study, which was presented to the client.
Smarter Solutions
After being awarded the project, the Intellect Systems electrical engineering team met with Transperth’s key stakeholders and operations staff to ascertain vehicle movements and schedules for consideration within the assessment. This included a site visit to determine potential electrical infrastructure install locations, electrical point of attachments, switchboard capacity & protection devices and reviewing the existing Transperth design documentation.
Electrical data logging information from the site was analysed to identify peak and average energy consumption and determine available network capacity and potential EV charging throttling requirements.
After establishing an understanding of Transperth’s needs and the site’s current capacity and layout, our engineering team reviewed the latest EV charging technologies and selected fit-for-purpose equipment to form the basis of the investigation and reporting.
Intellect Systems outlined potential risks with the project, such as the effect of a mains power outage, and provided strategies to mitigate these risks.
Concept design layout drawings were developed indicating potential equipment locations, spatial requirements, and cable reticulation pathways. A Rough Order of Magnitude was presented as part of the Study to assist Transperth with their financial planning for this project.
Intellect Systems guided Transperth in identifying possible EV charging infrastructure options for the Elizabeth Quay Bus Station and associated electrical network impacts to assist in determining the feasibility and best integration options.
