Provision and Installation of Solar Batteries for Joondalup Bus Depot

The Public Transport Authority of Western Australia (PTA), via its branded bus service Transperth, will be conducting an Electrical Vehicle Charging trial for a select bus fleet operating exclusively from Joondalup Bus Depot commencing approximately November 2021.

This procurement specifically includes the products and product installation as follows:

• 307.2 kWh / 150 kW storage batteries( x 4) to capture surplus electricity generation from the 100kw Solar System and redirect this surplus electricity to the EVC stations, giving potential for evening bus timetables and/or longer distance journeys and in general more flexibility in the management of the bus fleet.
• Simplistically, the desired order of precedence for managing surplus electricity would follow: Solar panels capture energy, this is stored within the batteries, then redirected to the Switchboard, then utilised by the EVC stations. Whilst the primary intention is to appropriately supply the EVC stations, the PTA seeks optionality from the battery system to supply electricity in varying proportions to either the fixed depot administration building, as well as, the EVC stations (at PTA’s discretion).
