What’s the latest update on Calgary Transit’s 40-Foot Electric Buses (BEBs)?

Updated October 2024

On October 3, 2024, we posted a request for proposals (RFP) seeking up to 180 zero-emission 40-foot BEBs that have proven public transit service hours in climatic conditions like Calgary. We plan to award the contract in early 2025 and expect our new 40-foot BEBs to arrive in late 2026 and hit the road before the end of 2028.

About the project

We spend a lot of time on the road, and incorporating lower-emission technology is an important step to reducing Calgary Transit's carbon footprint.

As our old diesel and gas-powered buses reach the end of life, we are diversifying and modernizing our fleet. This means adding vehicles powered by a number of different sources, including compressed natural gas, electric and gas-powered vehicles, in addition to diesel.

We’ve timed our fleet transition and battery electric vehicle purchases to take advantage of funding contributions from other levels of government and keep pace with Canada’s changing bus vehicle manufacturing industry.

What’s next?

We plan to deploy several 40-foot battery electric buses (BEBs). This bus electrification project supports our fleet transition to low- and zero-emission buses to help achieve The City’s corporate-emission reduction goals in the Calgary Climate Strategy - Pathways to 2050. This project is a good first step in our transition journey, as it will shift a good portion of our fleet to zero-emission buses. To prepare for BEB operations, we’re moving forward with an electric shuttle bus pilot project.

Battery electric bus benefits

By replacing end-of-life diesel buses with battery electric buses (BEBs), we aim to provide Calgarians with clean, quiet, and comfortable rides while reducing pollution, noise and exhaust. We expect BEBs to offer the following benefits:

Reduced Emissions: BEBs are projected to reduce our total fleet greenhouse gas emissions by approximately 8,500 tonnes of CO2 annually at project completion.

Lower Operating Costs: BEBs are less costly to maintain and operate over their lifespan compared to conventional diesel buses, thanks to reduced fuel and maintenance costs.

Alignment with Environmental Goals: Transitioning to BEBs is a core part of our commitment to lowering fleet emissions and advancing Calgary Transit’s sustainability initiatives, supporting the city’s broader climate goals.

Project funding

By taking advantage of funding contributions from other levels of government and incorporating all kinds of different fuel sources, we expect to be able to provide clean, quieter and more comfortable rides with less pollution, noise, and exhaust and lower operating costs.

FAQs

Does this mean Calgary Transit will eventually have an entirely electric bus fleet?

No. While we're introducing Battery Electric Buses into our operations, we’ll continue to purchase new 40-foot diesel buses, compressed natural gas (CNG) buses, and gas-powered 28-foot community shuttles. Our goal is to maintain a diversified fleet that includes electric buses to help reduce emissions where possible.

What changes can we expect in Calgary Transit’s vehicle fleet by 2027?

By 2027, our fleet will mainly consist of CNG, battery electric, and gasoline-powered vehicles, with diesel vehicles reduced from 48% to around 30% of the total fleet.

Will you replace diesel buses with BEBs before the diesel buses reach the end of their life?

No. We will only replace diesel buses when they’re at the end of their planned life.

Will you replace compressed natural gas (CNG) buses and gasoline shuttles with BEBs?

No. Our fleet acquisition budget for 2023-2026 includes funding for gasoline shuttles and CNG buses. We will adjust our fleet transit plan based on changes to technology, costs and funding sources throughout future business cycles and strategy implementation.

Are you gathering knowledge from transit agencies which already operate BEBs?

Yes. Transit agencies across the country and in North America are scaling up to integrate electric buses into their fleets, with major orders placed by entities like Winnipeg Transit, Regina Transit, Toronto Transit Commission, and in the province of Quebec with a multi-billion-dollar investment reflecting a widespread shift towards sustainable transportation solutions. We are in constant dialog with these agencies to learn from their experience to ensure our purchased BEB fleet is affordable, reliable, and helps reduce emissions.

Will BEBs perform in Calgary’s cold weather?

Over the past five years, the electric bus market has evolved significantly, there have been improvements to battery efficiency and battery management systems to perform in cold weather. We’ll purchase buses that have proven service hours in similar climatic conditions to Calgary. Rigorous testing of BEBs has been completed by transit agencies in Winnipeg, Toronto, Saskatoon, and Ottawa. Data and findings have been shared with us and helped to inform our procurement and technical requirements.

Did you consider hydrogen fuel cell buses as opposed to BEBs? 

Yes, but there are currently no hydrogen fueling stations available to us in the Calgary area, preventing hydrogen fuel bus operation. We’re focused on BEBs because we can move forward now to acquire BEBs and upgrade our garages with charging infrastructure using readily available federal government financing and funding to kick start our transition to a zero-emission fleet. We’re committed to evaluating and incorporating hydrogen fuel cell buses and other low or zero-emission vehicle technologies to reduce greenhouse gas emissions. We’ve started assessing hydrogen fuel technology through hydrogen bus strategy development and fleet integration studies and participation in a hydrogen bus pilot.

What’s planned to shift the rest of our fleet to zero-emission vehicles?

We’re developing a road map of how we will transition to a zero-emission fleet over the next 10 to 20 years. It will look at other alternate fuel sources, such as hydrogen and renewable natural gas.

Are BEBs a fire risk?

Like all vehicle fuel types, BEBs can catch fire. To reduce electric bus fire risk, we’re working with transit agencies across the country and participate in various Canadian Standards Association and National Fire Protection Association technical committees to develop fire and life safety guidelines for electric vehicle storage. This work includes lessons learned studies from European agencies that had fires with their vehicles.

Are BEBs safe?

Road and passenger safety is our top priority. Our bus fleet complies with all applicable provincial and federal transportation and motor vehicle safety standards and laws. Our BEBs will also follow all applicable provincial and federal transportation and motor vehicle safety standards and laws. All our buses follow Transport Canada’s Canada Motor Vehicle Safety standards, which include safety requirements for buses, such as brake and visibility systems, window retention, emergency exist requirements, lighting, tires, and wheels. All our buses are designed to carry maximum passenger loads and are regularly inspected and maintained to ensure mechanical integrity. The BEBs we purchase will have undergone rigorous Altoona Bus Testing, which tests buses for reliability, safety, performance, structural integrity, durability, fuel/energy economy, noise and emissions.

How will heavier BEBs impact Calgary’s roads?

BEBs are generally heavier than diesel or compressed natural gas (CNG) buses. In Canada today, 40-foot BEBs are, on average, up to 20 per cent heavier than 40-foot diesel or CNG units. BEBs, like our diesel and CNG buses, will require provincial overweight permits to operate in Calgary. Heavier vehicles including BEBs can negatively affect road infrastructure. To understand the impacts, we’re gathering knowledge from other Canadian municipalities that operate BEBs and have evaluated pavement quality impacts, such as Winnipeg Transit. We’re also working closely with The City’s Mobility team to understand and prepare for road impacts in Calgary. The impacts of BEBs will depend on the vehicle weight, existing road condition, road design, structure conditions, structure design, and frequency of BEB service.

Can Calgary Transit source both battery electric shuttle buses and 40-foot battery electric buses from the same supplier?

That's unlikely, as there are currently no North America suppliers that produce both the battery electric shuttles and 40-foot battery electric buses we need for our projects. We would consider electric bus manufacturers in Europe that produce both shuttles and 40-foot buses, providing their vehicles meet Canadian Motor Vehicle Safety Standards required by Transport Canada.
