Hydro-Québec and its subsidiaries are taking part in feasibility studies and pilot projects to precisely determine the infrastructure needed to develop electrified public transit. The company’s goal is to evaluate its level of investment in the electrical component of this infrastructure.
Since 2016, Hydro-Québec has been collaborating with the Caisse de dépôt et placement du Québec Infra on the Réseau électrique métropolitain light rail train project for Montréal.
Current pilot projects
- All-electric school bus – Autobus Lion
- All-electric BYD bus with slow charging – Société de transport de Laval and Société de transport de l’Outaouais
- All-electric Nova Bus with charging at the end of the line – City Mobility in association with the Société de transport de Montréal
- Electric vehicle carpooling – Project CLIC, in association with the Société de transport de Laval and the Agence métropolitaine de transport
Current feasibility studies
- Streetcar – Ville de Montréal, Réseau de transport de la Capitale and Société de transport de Lévis
- Trolleybus – Société de transport de Montréal and Société de transport de Laval
- Commuter train electrification – Agence métropolitaine de transport
- Aérotrain rail shuttle – Aéroports de Montréal
Understanding the different modes of electrified public transit
Hydro-Québec provides a source of clean, renewable hydropower.
Hydro-Québec is currently participating in feasibility studies conducted by various public transit authorities to determine exactly what electrical infrastructure is needed and what Hydro-Québec's level of investment might be in this infrastructure.
- ATransformer: lowers AC voltage from 25,000 volts to 600 or 750 volts.
- BRectifier: convert alternating current (AC) to direct current (DC).
- CCatenary: overhead line that follows the path of an electric mass transit vehicle and supplies it with power. Common catenary voltages for a trolleybus are 600 and 750 volts DC.
Public transit vehicle
- DTrolleybus: has rubber tires, like a bus, but is powered by an electric motor.
- ETrolley pole: draws electricity from the catenary to power the trolleybus. The pole must be able to move vertically and laterally to accommodate the movement of the trolleybus.
