Montreal’s tree-lined streets are one of the city’s greatest assets — they clean the air, add bursts of green to the scenery and help push the concrete background. But when storms hit, those trees clash with the urban landscape and are a major cause of power outages. That’s why Hydro-Québec is now using new technologies to find a way for trees to coexist with its power lines. “We’re trying to make a digital twin of the network to see if there are interactions between the tree and the network,” said Étienne Langdeau, director of vegetation management for Hydro-Québec. Artificial intelligence then measures the trees before and after a weather event, like a windstorm, to see which branches broke. The algorithm uses this information to get better at predicting which branches are most likely to snap. In turn, technicians can preemptively cut these branches before they become a problem.
