The most common mistake in transitioning to an electric fleet is starting the planning from the vehicle. Experienced operators' roadmap works in reverse: depot first, vehicle second. Because if the charging infrastructure is inadequate, even the best electric vehicle turns into capital sitting idle in the yard.
The Steps of Depot Planning
- Grid analysis: Measuring the facility's existing electrical connection capacity; early contact with the distribution company if the transformer and line capacity need to be increased
- Charging profile: Working out the hours vehicles spend at the depot; slow overnight charging is both cheaper and sufficient for most operations compared to fast charging
- Smart load management: Software that charges all vehicles not simultaneously but by priority order; it lowers peak power demand and the electricity bill
- Yard layout: Positioning charging points so they do not disrupt parking and manoeuvring flow; the ability to charge while the trailer is still coupled
- Room for the future: Sizing cable ducts and panel capacity for the target fleet size, not today's
A Phased Transition
The common pattern among successful examples is the pilot: a few predictable routes that return to the depot every evening are electrified first; real consumption data is collected, and the infrastructure is scaled using that data. Additions such as solar panels and stationary battery storage at the depot are the next steps in managing electricity cost. An electric fleet is not a procurement project but an infrastructure project; budget and timeline must be set accordingly.
