A bus operator with a fleet of 1,400 electric vehicles has kicked off a smart charging trial across its depot network. Rather than charging all buses simultaneously, the system adjusts when each vehicle draws power, responding to real-time grid conditions and shifting demand away from peak hours.
Smart charging at scale offers a compelling value proposition for grid operators: large depot fleets represent significant, controllable loads that can act as virtual demand-response assets. Instead of requiring costly grid infrastructure upgrades, operators can monetise flexibility while cutting their own energy bills.
Across the EU, integrating heavy transport electrification with grid services is gaining regulatory momentum. The revised Electricity Market Design directive and the Energy Efficiency Directive both encourage demand flexibility, making smart charging for bus and truck depots an increasingly attractive commercial opportunity.
If successful, this trial could serve as a blueprint for other public transport operators and logistics companies looking to deploy large EV fleets responsibly. The ability to provide grid-balancing services may also improve the business case for fleet electrification in markets where grid connection costs are a major barrier.
