Proterra delivers 100th electric bus

Proterra delivered its 100th battery-electric bus, destined for San Joaquin Region Transit District (RTD) in Stockton, Calif. Proterra is leading the industry with more 60% of electric bus sales since the industry’s inception.

Proterra has delivered its buses to 36 different municipal, university and commercial transit agency customers in 20 states. Many of the transit agencies serving these communities have also completed third and fourth orders for Proterra buses including San Joaquin RTD, King County Metro in Seattle and Foothill Transit in Pomona, Calif.

Serving more than 687,744 people in San Joaquin County, RTD has added ten more Proterra Catalyst battery-electric buses to its expanding fleet, bringing its total number of Proterra buses to 12. San Joaquin RTD is the first agency in Northern California to operate all-electric technology.

To date, Proterra buses have completed more than 3,100,000 miles in revenue service, which equates to ~6,000 tons of GHG emissions reduced and more than $2 million saved in fuel and maintenance costs. On a total cost of ownership basis, these vehicles can save transit agencies up to $459,000 per bus over diesel-hybrid vehicles and up to $448,000 vs. diesel vehicles over their lifetime, the company said.



Total city e-buses operating cost is very misleading.

Montréal QC first city e-buses spend/require 6+ minutes (per hour) or 10+% of the time charging. Lower availability will require 300+ more buses and 750+ more very costly drivers.

Charge times + extra buses/drivers + higher initial cost will more than offset potential savings.


BYD's big battery solution would not have that downtime.

I think that they are not getting the contracts because they are regarded as 'too Chinese'

Hydrogen buses would also avoid that problem and refuelling at the depot is straightforward for them at good cost:

'The biggest benefit of hydrogen fuel cell buses: they emit nothing except water, said Conrad. And while compressed natural gas is less polluting than diesel fuel, CNG engines still emit some pollutants, and hydrogen is more than twice as fuel efficient than CNG and diesel engines. Electric buses are also zero-emission vehicles, but they have to be recharged every hour to two hours. But hydrogen, which currently costs about $4.63 a kilogram, for now, provides no fuel savings due to the plunge in oil prices the past year.

If this experiment in Canton is a success, then the results could be cleaner air, more adaptation in Ohio and nationwide of hydrogen fuel cell technology to help accomplish the goal of zero-emission vehicles, the establishment of a vehicle hydrogen fuel cell research program at Stark State, and the development of a local fuel cell industry that would result in more high-paying jobs.'

The air filtration also means that they clean the air, instead of adding more pollution to it, which BEVs don't do.


I fully agree with you that e-buses and FC-buses with enough range for 8 or 16 hours use could be ideal to replace current diesel polluting units.

Unfortunately, the initial cost of those ideal units is still too high and would not be competitive (yet).



The Proterra buses are available with up to a 350 mile range which for a transit bus is probably more than a full day of service and the costs of ownership are less that of diesel buses. I think that Proterra is currently production limited.


I do not know where the bogus concept of fuel cell vehicles cleaning the air came from but one could just about as well make the claim the Tier 4 final diesel engines clean the air as in some polluted places the exhaust is cleaner than the intake.



Yes, e-Buses or FC-Buses with 350 miles (about 500 KM) range could run for a full double shift most of the time.

Can they be produced at a competitive price? If so, where are they used?

Articulated (100+) passenger electrified units may solve drivers' very high cost.
