Current State of Electric Bus Market• Battery-electric bus manufacturing and technology are still new but
progressing rapidly.
• Dozens of transit agencies in the US with electric bus experience – most with less than 10 buses
• Currently, six agencies in the United States are operating 10 or more electric buses.
• The industry is currently focusing on 40-foot standard bus designs. Offerings in the 60-foot articulated bus category are still limited.
• Electric bus manufacturers include New Flyer, Nova, Gillig, BYD, and Proterra.

Electric Bus Projects in the US• Key agencies with electric bus experience:
• King County Metro: 120 electric buses by 2020
• IndyGo: 34 buses, 18 more on order
• Antelope Valley Transportation Authority: 30 electric buses (two 60-foot), anticipated 100% conversion in 2019/2020.
• Foothill Transit: 37 buses, 100% fleet conversion by 2030
• California Air Resources Board mandate for transit agencies to transition to electric buses by 2040
• 425,000 electric buses deployed worldwide (99% in China)

Mechanisms: Continuous Charging
Trolleybuses require overhead catenary wire for most of their route.
This is also called In Motion Charging (IMC) when buses spend significant time off-wire.

Charger Cost + Slow-chargers typically cost less to
purchase/install.
― Fast-chargers typically cost more
to purchase/install.
Garage Space ― Somewhat reduced garage capacity,
likely need for indoor storage.
+ Lessened garage capacity impact.

Real World Performance
• Transit agencies should anticipate:• How much energy (kWh) is consumed per mile?
May increase 64% to 75% on very cold days due to heating
May increase on hot days due to aid conditioning
Also varies based on driver behavior (acceleration, braking)
• Battery capacity will degrade over time
• Not all of the battery capacity is usable (to avoid damage)
• There should be a minimum reserve capacity drivers do not go below (to avoid breakdowns)

Planning Needed to Adopt Electric Buses:

![Page 35: Planning for Adoption of Electric Buses … · Electric Bus Projects in the US • Key agencies with electric bus experience: •King County Metro: 120 electric buses by 2020 •IndyGo:](https://reader033.fdocuments.net/reader033/viewer/2022042400/5f0e4eff7e708231d43e9cdf/html5/thumbnails/35.jpg)
Schedule AnalysisPurpose Determine whether electric buses can actually operate the transit
service they would be assigned
Methodology Obtain the schedules of trips that buses would be assigned to
operate Calculate each bus’s state of charge as it completes its schedule
Charge declines based on miles traveled
Charge increases if on-route charging occurs
Identify what service is difficult to electrify so agency can make changes
Repeat for various technologies being considered

Where Are On-Route Chargers Feasible?
Agency owns the layover space
There is space for the charging cabinet
Buses have dedicated bays (not back-to-back, not on street)
![Page 42: Planning for Adoption of Electric Buses … · Electric Bus Projects in the US • Key agencies with electric bus experience: •King County Metro: 120 electric buses by 2020 •IndyGo:](https://reader033.fdocuments.net/reader033/viewer/2022042400/5f0e4eff7e708231d43e9cdf/html5/thumbnails/42.jpg)
Identify locations that would be used the most by electric buses
More chargers can make more service eligible for BEBs
On-route chargers are very expensive…
Develop Network of On-Route Charger Locations

Planning Needed to Adopt Electric Buses:

![Page 46: Planning for Adoption of Electric Buses … · Electric Bus Projects in the US • Key agencies with electric bus experience: •King County Metro: 120 electric buses by 2020 •IndyGo:](https://reader033.fdocuments.net/reader033/viewer/2022042400/5f0e4eff7e708231d43e9cdf/html5/thumbnails/46.jpg)
Depends on lifetime of a bus. A bus fleet naturally turns over through one lifetime.
Example: The TriMet bus fleet naturally turns over from 2020 to 2036. Their bus lifetime is 16 years.
Replacing an Entire Fleet

Building a Cost Model Create a “fleet progression” showing
what vehicles will be in use during your planning period
For each cost category you model, create a new tab that follows the structure of the progression
Accounting assumptions:
Inflation rate for future years
Discount rate for future dollars
Show one scenario or a range of possibilities?
