BAE Systems announced it will supply up to 541 Gen3 electric power and propulsion systems for the Toronto Transit Commission’s (TTC) new fleet of battery-electric buses, allowing them to run free of emissions.

BAE Systems’ electric propulsion technology has been operating in TTC buses since 2006.

The company’s Gen3 offering builds on those proven components and technical expertise that has powered more than 1,000 hybrid-electric buses in Toronto.

The system will advance the TTC’s goal of transitioning to a zero-emissions fleet by 2040. 

“Delivering leading-edge technology to help Toronto realize its green transit initiatives is a shared vision for BAE Systems and the TTC,” said Bob Lamanna, VP/GM of Power & Propulsion Solutions at BAE Systems. “The TTC has consistently embraced sustainable transportation, and our systems will help make our vision a reality through reliable, efficient operation.”

BAE Systems’ Gen3 System

BAE Systems’ Gen3 system includes an electric motor and innovative power electronics to create an integrated power management solution for the buses.

Gen3 uses advanced materials such as silicon carbide (SiC) to increase power density and electrical efficiency, allowing buses to travel longer distances on a single charge. Its compact design allows for reduced size and weight to deliver reliability and performance. 

The system requires fewer components and connections, which contributes to reduced operational costs and maintenance requirements to maximize fleet productivity.  

BAE Systems’ proprietary Intuitive Diagnostic Software (IDS), already in use at TTC for its hybrid bus fleet, will provide full electric propulsion and accessories power management system diagnostics and troubleshooting capabilities. IDS updates cover all Gen3 system components.
