Although our equipment is robust and can withstand most adverse weather conditions, vegetation near the power distribution system is a little more vulnerable to the whims of Mother Nature.
When it’s very windy or stormy, branches may come into contact with system components and cause power outages.
There are four steps to restoring service:
- Next-generation meters and our monitoring systems detect the outage and quickly alert our control centre, which operates 24/7. We first try to restore power to the lines using remote operations.
- If the problem persists, a team is dispatched to inspect the system and identify the cause of the outage. This step can take a long time, especially in poor weather.
- Once the cause of the problem has been found, the on-site crew evaluates the extent of the damage and determines what corrective measures are required.
- We then assign the appropriate teams to do the job, whether it involves cutting branches or replacing damaged equipment. Our teams cannot restore service until all these steps have been completed.
Losing power is never fun, but rest assured that when outages occur, hydroquebec crews do their utmost to restore service as quickly as possible. But what causes outages?
In summer and winter alike, Hydro-Québec’s electric power distribution system is put to the test.
Although our equipment is robust and can withstand most adverse weather conditions, vegetation located near power lines is a little more vulnerable to the whims of Mother Nature.
When there are strong winds or violent storms, contact between branches and system elements can cause a power outage that can affect many customers.
Since the most violent storms occur between June and August, it’s no surprise that most power outages happen during the summer. In winter, heavy snow often bends branches or trees to the point that they touch power lines, causing outages.
