Toronto Transit Commission orders 10 battery-electric buses from New Flyer, option for 30 more
http://www.greencarcongress.com/2018/06/20180622-ttc.html

. . .This award supports TTC’s electric bus program, focused on transforming its fleet into a 100% zero-emission fleet by 2040 and buying only emission-free buses starting in 2025.

TTC announced an order of 10 Proterra electric buses last week. (Earlier post.)

New Flyer was one of three candidates invited to collaborate with TTC in the evaluation of battery-electric buses for TTC service, offering buses with long range and overnight charge capability. The collaboration will assist TTC and the greater public transportation community with the development of bus specifications and the integration of future electric-bus procurements.

The Xcelsior CHARGE award is supported by funding from Infrastructure Canada’s Public Transit Infrastructure Fund (PTIF), which provides funding for new capital projects and planning and studies for transit growth in support of long-term transit plans. TTC’s electric bus program is also funded in part through the Government of Ontario’s GHG Challenge Fund. Depot charging for the buses will be powered by Toronto Hydro, TTC's electricity provider.

BYD delivers first battery-electric bus to IndyGo
http://www.greencarcongress.com/2018/09/20180913-byd.html

IndyGo, the largest public transportation provider in the state of Indiana, and BYD announced the delivery of the first K11 60-foot battery-electric bus to serve Indianapolis. The bus is the first of 13 ordered for the Red Line by IndyGo.

This K11 will serve IndyGo’s Red Line, a 13.1-mile route that runs between Broad Ripple on the north side of the city and the University of Indianapolis on the south side, offering more frequent service and longer hours than current routes. The Red Line is the densest corridor in terms of population and employment within Marion County.

The bus purchases are part of IndyGo’s plans to replace all its diesel buses with electric models by 2032 . . . At least some of the energy required to charge the buses will be derived from a 1 megawatt Solar system mounted atop IndyGo’s garage.

Interesting they would attempt that for the PC-SLC route. I wonder what the specs would look like for a model to handle the climbs (and downgrades) over that distance.
Looking at the timetable for that route, it appears it is designed to be handled by two buses, both garaged in Salt Lake City. Each bus makes four round trips daily each of which is comprised of 2 55- to 65-minute one-way trips with six stops each and a 10-minute stop at each terminus. The one-way distance traveled is 26 miles for a total of 208 miles each day. Total time on the route each day is 8.5 hours (excluding the 5.5 hours of breaks in SLC in the middle of the day).

If the vehicle rests and charges during the entire 5.5-hours of breaks each day, this route can be easily serviced using Proterra Catalyst E2 Max buses. That would only require the buses travel 104 miles over a 4.25-hour period before being fully recharged. That would only require a minimum efficiency of 5.8 kWh/mile or an average draw of 70 kW or less while enroute (assuming 600 kWh used each half-day).

The worst-case scenario is for a 660-kWh Proterra bus that is only charged at night and serves other routes in SLC for the other five hours of the day. In that case, the total driving range for the day would approach 300 miles. If we assume no charging during the entire 14-hour day, the minimum efficiency required would be about 2 kWh/mile (assumes 600 kWh used). That seems extremely unlikely for a vehicle which achieves an efficiency of only 1.89 kWh/mile without HVAC.

Another idea is that the bus travels the 300 miles but is charged at each of the terminus locations for a total of about 120 minutes per day. According to Proterra's specifications, their E2 buses can charge at 325 kW using the overhead charger. This approach could add another 650 kWh of charge through the course of the day. Adding that to the 600 kWh that was available at the start of the day, that comes to a total of 1250 kWh available, which would allow the completion of this route structure even if average efficiency dropped to 4.2 kWh/mile. This is equivalent to an average draw of 89 kW over the course of the entire 14-hour day.

In any case, use of the Proterra buses on this route will significantly reduce energy consumption as well as overall cost when compared with the use of a diesel bus.

These buses when equipped with the Duopower drivetrain can climb a 23% grade, so there is no issue with the slopes involved.

My conclusion is that this route can be handled by buses which are currently available from Proterra. Operational considerations will determine what features the buses need in order to meet the requirements.

First Blue Bird electric school buses delivered in North America
http://www.greencarcongress.com/2018/09/20180930-bluebird.html

Blue Bird just delivered the first electric-powered school buses to customers in California and Ontario, just in time for the new school year. Seven Type-D All American Rear Engine Electric school buses and one Type A Micro Bird G5 Electric school bus will be in operation this year.

All of the customers who obtained electric school buses were able to do so through the help of financial grants offered by various entities and government programs. These grants helped to pay for all or part of the cost of the buses, as well as some necessary infrastructure costs.

Jack Matrosov of Wheelchair Accessible Transit, based in Toronto, Ontario, was able to add a Micro Bird G5 Electric school bus to his fleet through the use of the Electric and Hydrogen Vehicle Incentive Program (EHVIP), which is offered by Ontario’s government. The grant also allowed him to cover nearly all of the costs of the infrastructure needed for this bus.

The larger, 72-passenger buses ordered by customers in California have a similar design to the many Blue Bird Type D CNG buses that districts operate in the state today. These districts utilized many California-based grants, including South Coast AQMD and HVIP, which helped to pay towards the cost of the buses and infrastructure. . . .
