Understanding Electric Vehicle Fueling Costs Compared to Gasoline for Fleets

Gasoline or diesel prices could fluctuate 20% in a given year, whereas fully bundled electricity rates could vary by as much as 300% in a given day. The complexity of electricity rate structures coupled with confusing or conflicting metrics is a fundamental impediment to a global transition to electric vehicle (EV) fleets. For this transition to happen, fleet operators need to be equipped with the tools, information, and partners to understand, plan, budget, and operationalize such a paradigm shift.

To that end, and as one contributing component, AMPLY Power has developed the Dollar per Gallon-equivalent (DPGe) metric. The DPGe is a direct, apples-to-apples comparison that allows us to compare the electric dollar per gallon-equivalent of gasoline (or diesel) for specific cities, incorporating regional-specific electricity rate structures, fleet-specific charging strategies, and vehicle class efficiencies into a single, comprehensible metric that can be used by fleet operators to assess, plan, and budget for a fleet transition.
