Transperth has completed its largest EV bus depot in Perth, with 56 dual chargers and 112 plugs, raising questions about fitting electrification into whole-of-government net zero transition plans. The retrofit process involves assessing grid connection, upgrading substations, installing chargers, and rebuilding yards, highlighting the need for a network-wide electrical strategy for future electrification demand. The article discusses challenges and opportunities in transitioning to a more sustainable energy system in Western Australia, emphasizing the importance of precinct scale electrification planning. The disciplined approach taken by the WA transport minister in gradually transitioning the fleet to electric vehicles and building depot capacity ahead of demand is praised, but a more comprehensive and forward-looking energy planning approach at a precinct level is needed for long-term sustainability.
