A Global Innovation

One of the most remarkable innovations of the canal was, without a doubt, its electrification.

The hydroelectric power generated by the small Les Cèdres power station—known locally as Petit Pouvoir—at the junction of the canal and the Rivière à la Graisse was a world first in maritime transport.

This electricity enabled the automatic operation of lock gates, water supply and drainage valves, swing bridges, and entrance lighthouses. Most notably, the canal was illuminated by streetlamps installed along its entire length, allowing vessels to navigate both day and night.

However, while the canal opened in 1899, the lighting system was only operational by 1900, and it was not until the spring of 1902 that all structures ceased to be manually operated.
