Québec has not only an abundance of clean, affordable energy but also motorization and energy storage solutions, which are key assets in efficient transportation electrification. Montréal’s metro, which transports over a million people daily and has been in operation for half a century, is a valuable tool in combating GHG emissions. Several electric transportation projects lie ahead, including the Réseau express métropolitain (REM light-rail system), the Blue line metro extension and the addition of electric city buses.

Since the transportation sector is the main source of GHG emissions in Québec, the adoption of electric vehicles, active transportation and mass transit are an important way to reduce air pollution.

Hydro-Québec is collaborating in the REM project, a driverless light-rail system spearheaded by the Caisse de dépôt et placement du Québec Infra. The company will contribute mainly by integrating its infrastructure and substations to supply electricity for the system.


  • After launching its first SUMO system five years ago, TM4 began marketing its SUMO HP powertrain in 2017. This model joins the SUMO MD series for medium-duty commercial vehicles and the SUMO HD series for heavy-duty commercial vehicles.
  • TM4 and Cummins worked together to develop a plug-in hybrid powertrain intended for use in city buses, which could reduce fuel consumption by at least 50% compared with conventional hybrid technologies. The project aims to offer transit authorities a flexible and more efficient motorization solution that provides electric vehicles with a substantial range.
  • We signed an agreement with Lawrence Berkeley National Laboratory (U.S. Department of Energy) to create a joint Québec–Berkeley research center, dubbed QUBE, in the San Francisco Bay area. The center’s mission is to speed up the development of next-generation battery materials, processes and technologies, and conduct manufacturing from pilot scale to preproduction levels. The technologies developed will then be transferred to battery manufacturers, which will create jobs in Québec and California.
  • TM4 and AxleTech International designed an electric axle featuring a built-in powertrain for heavy-duty vehicles—a solution that will make it possible to electrify vehicles without adding to their bulk.
  • In partnership with Ecotuned Automobiles, we converted a Ford F-150 truck into an electric vehicle by installing an electric motor with an estimated useful life of one million kilometres. The system is also reusable and can be transferred to another vehicle. The truck has joined our vehicle fleet, where its performance and reliability will be assessed.

Electric Circuit

By the end of 2017, the Electric Circuit a Hydro-Québec initiative—boasted 1,271 charging stations, including 1,175 240-V stations and 96 fast-charge stations (400 V), in 16 of Québec’s 17 administrative regions.


  • This year saw strong growth in the Electric Circuit, which now has 1,271 charging stations in 16 of the province’s 17 administrative regions. It has also expanded beyond the Québec border with the rollout of 18 charging stations in Ontario. In all, 1,183 regular (240-V) charging stations and 106 fast-charge stations (400-V) are deployed at 801 service points in 239 cities and town. The number of fast-charge stations increased from 66 to 106 in a year, primarily along Québec’s main highways.
  • Québec’s first fast-charge superstation was launched. This facility, which has a number of fast-charge stations, will serve as a test bench for new charging technologies as well as various complementary services such as dynamic pricing options. Users’ comments will be gathered to improve future superstations. (Montérégie)
  • A total of 18 new charging stations were installed in the parking lots of our buildings. The company now has 83 charging stations at 34 sites, 20 of which are Electric Circuit stations and can be used by the general public.
  • The Electric Circuit expanded into Ontario, with the installation of 18 charging stations along highways 401, 416 and 417 and Route 17. In Ottawa and the surrounding area, eight 240-V and 10 fast-charging stations were installed.
