Reducing outages

Some 40% of outages that affect the distribution system are caused by vegetation overgrowth. This percentage rises to 70% during major weather events, significantly affecting service continuity and customer satisfaction. To limit the phenomenon, Hydro-Québec has increased its investments, which rose from $62 million in 2018 to $99 million in 2022, and its preventive vegetation management interventions in addition to reviewing clearing cycles, in particular by targeting trees at risk. Another targeted action consists of prioritizing maintenance, improving 60% of overhead lines, increasing the reliability of 400,000 overhead transformers and rebuilding 2,600 km of distribution lines.
