Sign up for Our Outage Management System
Over the past several years London Hydro has worked hard to improve the reliability of our system to ensure that Londoners have a safe, reliable supply of electricity. As a result, we have seen improvement in both outage frequency and outage duration.
Continuing with those improvements we've developed an Outage Management System that will help us provide you with important information in the event of a power outage, such as when you can expect it back on. Estimated restoration times are not always available, especially if we are still looking for the problem, or if there are multiple outages in a storm, however we will do our best to give you as much information as is available.
Once you register, you will be notified by your choice of either email, phone or text as soon as we are aware of an outage affecting your address. If an estimated restoration time becomes available or needs to be adjusted, you will immediately receive another notification.
