At Thunder Bay Hydro, we understand that your electricity service is very important at all times. When we are working in your area, we will provide general notices to warn you of expected power outages.
Unplanned interruptions are usually a direct result of storm damage, vehicle accidents, animals, or other unexpected events such as digging that hit an underground power line. Learn about Call Before You Dig.
When an outage occurs, we work first to identify the problem, get crews to the site and ensure that proper safety procedures are in place. Then we will update our outage line with the information that we have gathered. This takes time. Please expect at least a 30 minute time lag.
When an unplanned outage is going to last for hours or affects a large area for a prolonged time, it will be classified as a MAJOR outage. We monitor and update our social media channels (Twitter and Facebook) during MAJOR outages only.
Auto-reclose incidents are one of the main reasons for short periods of power loss.
Electricity can seriously injure or even kill. When an object such as a tree, bird or animal touches the overhead wires in such a way that grounding occurs, a fuse will open up and cut power to allow for the object to clear the line. The fuse will then close and power is restored.
In cases where the line is still interfered with, the fuse will open again and a Thunder Bay Hydro crew is sent to the area.
Unfortunately, whether the outage is a second or several minutes, customers who do not have battery backup on appliances or equipment are frustrated by the need to reset clocks and timers.
Periodically, scheduled interruptions are required to perform maintenance on our system or to your meter. These infrequent interruptions are intended to be of short duration. If work that may require an outage is planned for your neighbourhood, you will be notified.
Trees are often the cause of downed power lines. You should not plant trees that will grow tall directly under power lines. Learn about our tree trimming program.
