What Causes Power Outages

Planned Outages
With over 10,000 kilometres of transmission and distribution lines, planned outages are occasionally needed to allow our crews to perform preventative maintenance. When possible, we provide advance notice indicating the time and expected length of the outage.

Unplanned Outages
Unplanned power outages are caused by things such as high winds, snow and ice storms, salt spray, lightning, and other severe weather conditions. Outages can also be caused by equipment problems, vehicle accidents, fallen trees, and even animals contacting power lines.

If a power outage affects only one part of your home, it is probably due to a problem in your electricity panel such as a tripped circuit breaker or a blown fuse. If resetting the circuit breaker or replacing the fuse does not restore power, you may require an electrician to investigate.
