PowerON is designing, building, operating, maintaining, co-investing and owning all electrification infrastructure to support electrification of the TTC bus fleet and facilities.

In 2019 the Toronto Transit Commission (TTC), Canada’s largest municipal transit agency, came to PowerON with the ambitious goal of fully electrifying its bus fleet by 2035. The transition of its fleet of over 2200 buses to 100 per cent zero-emissions technology is would become North America’s largest, most ambitious transit electrification project.
Achieving this however, would require overcoming multiple challenges; including getting sufficient electricity to its sites, ensuring the reliability needed for revenue service, and the space constraints of the TTC’s facilities.
To address these challenges, PowerON began with overseeing detailed feasibility studies for each of the TTC’s eight garages based on a deep understanding of the TTC’s unique operational needs. The output of these studies enabled PowerON to develop a phased electrification plan that would minimize risk and support change management across the TTC’s operations and with external stakeholders.
We are now executing on that plan, in which PowerON’s scope includes installation of chargers, battery storage, backup generation, and operation of the energy management system that ties them all together.
Phase I of PowerON and the TTC’s 15 year construction schedule is underway at several of the TTC’s facilities with chargers already operating at TTC Birchmount and more coming online through 2023.
