The Chicago Transit Authority
reports that the transition will require an extra $1.8 to $3.1 billion taxpayer dollars in order to fund the transition, as opposed to diesel trucks.
In order to make that transition, cities will have to invest heavily in green infrastructure, like charging stations and batteries, or staffing electrical engineers.
“The operating savings from a fully electric fleet is expected to be offset by ongoing capital costs that are reduced compared to the transition period, but continue to be somewhat higher than diesel scenarios even after the transition is complete,” the CTA's report said.
Put simply, post-transition will entail cost savings in daily operations, like lower fuel and maintenance costs. And once the transition is complete, these capital costs will decrease because the initial infrastructure investments have already been made, but will still be higher than a diesel fleet.
Annually, CTA estimates those capital costs to be $90 million greater than for a diesel fleet, attributed to “the added cost of replacing chargers and the projected higher costs to purchase and overhaul electric buses.”
“Electric buses can be cost competitive when their costs and benefits over their lifetime are considered but remain more expensive when only considering upfront costs, due to the cost of the batteries,” according to a report from C40 Cities Climate Leadership Group.
So consumers may see a short term increase in their electricity bill.
The CTA is aiming to have the transition complete for nine neighborhoods by 2040, with an average implementation rate of 4.77 years.
