The Toronto Transit Commission (TTC) announced it will receive up to 541 Gen3 electric power and propulsion systems from BAE Systems, a heavy-duty electric propulsion provider, for its new fleet of battery-electric buses. This purchase decision supports TTC’s goal of having 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, Vice President and General Manager 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 includes an electric motor and power electronics, and it utilizes silicone carbide to increase power density and electrical efficiency, allowing the buses to travel longer distances on a single charge.  The Gen3 also features a simplistic design – by having fewer components and connections, BAE Systems can reduce maintenance requirements and TTC’s operational costs.

This deal serves as a continuation of the partnership between BAE Systems and TTC that has been ongoing since 2006. In that time, BAE Systems’ propulsion technology has been used to power more than 1,000 hybrid-electric buses throughout Toronto.
