A robotaxi depot is an energy logistics site, and depots are what will set the pace of fleet growth
A conventional fleet yard parks vehicles overnight while drivers are off shift. A robotaxi depot runs all day: vehicles arrive with low charge, get inspected and cleaned, charge, wait in a staging queue and return to service. At about 50 kWh per vehicle per day, a 500-vehicle depot moves roughly 25 MWh of energy a day, averaging about 1 MW and peaking several times higher when demand drops and many vehicles charge at once.
That makes the depot the physical bottleneck for fleet growth. Waymo's plan to reach 20,000 vehicles by the end of 2027 implies dozens of new depot sites, each with utility service, permits and staff for cleaning and repairs, and Waymo already uses fleet partners for those tasks in some cities. Automated charging - robotic plug-in or inductive pads, which Tesla has said Cybercab will use - removes the last routine human task. Depots with battery storage can charge from the grid off-peak and avoid demand charges; those with on-site solar and storage edge toward Energy Autonomy Yards. The same design will extend to driverless truck terminals.

Conventional depot vs. autonomous depot
Load figures are ElectronsX estimates.
| Attribute | Conventional depot | Autonomous depot |
|---|---|---|
| Operating model | Parking and overnight charging | Continuous arrival, service and redeployment |
| Human role | Drivers park and plug in | Technicians handle exceptions; charging automated |
| Energy profile | Overnight peak | All-day load with peaks when demand drops |
| Key metric | Vehicles ready by morning | Minutes from arrival to dispatch |
| Site needs | Parking and chargers | Cleaning bays, inspection lanes, staging, megawatt service, BESS |
