The TCO analyses that will be available via the Electrification Coalition rely heavily on data and methodologies sourced from the US Department of Energy’s Alternative Fuels Data Center (AFDC) as well as the GREET model. The modeling from the EC is designed to provide an unbiased TCO analysis but will make recommendations for the right use cases to maximize. But many cities or fleets might have specific use cases/application that are not specifically focused on maximizing the TCO.
The TCO estimate takes into account local variables like gas prices verses electricity costs, average daily miles, and other cost factors. For each city, the actual TCO will ultimately depend on the final cost of acquisition, how a vehicle is utilized relative to the vehicle it replaced, and if there are opportunities to increase the number of electric miles driven per vehicle which will lead to a lower overall TCO.
Though very relevant to inform city decision making on EV procurement, the additional benefits of EVs such as hitting local policy goals, improving local air quality, and reducing city GHG footprint are not included in this analysis.
