Agreed that is the best operational approach to capacity fade in BEV buses. Still, I wonder if you can really get 12 years of daily use out of any of today's batteries.
Also, looking at the chart that I posted, I have to say that there is a real discrepancy between the graph and the words written on the graph. The words say "$448K versus diesel" but the graph says $175K. The words say "$409K versus CNG" but the graph says $150K. The words say "459K versus hybrid" but the words say $380K. Caveat emptor, I suppose.
You have to start from the base of fuel and maintenance, i.e. ignoring the vehicle cost ("lifetime operational
savings") to get their numbers.
Restricting vehicles to only shorter routes as they age is a lot better in theory than practice. It can make scheduling and dispatching a royal pain, and lead to missed trips if you don't have the right vehicle available at the right time. If you've got a large fleet you may be able to make it work, but with medium and smaller size fleets it may well wind up costing you more, as you have to try to rent to cover the shortfalls.
