EDF Report: Power Resiliency for Electric Fleets
Resource Library

When fleets trade in gasoline or diesel vehicles for electric vehicle (EV) models, they are also trading traditional fuel suppliers for electric utilities. Fortunately, electric power systems in the United States are extremely reliable—utility customers enjoyed 99.9 percent uptime in 2021 [1]. Due to that reliability, most fleets will find they can switch to EVs with little need to address outage risk. However, in some cases (such as vehicles that provide emergency services), power outages may pose a large enough threat to their fleet operations that the risk of outages must be mitigated with planning and backup power systems.
