How We Restore Power


Illustration of how power is restored in OntarioWhen the power goes out, the cause can either be on the Guelph Hydro electricity distribution system or upstream from us on the Hydro One transmission system that carries electricity from generating stations to our community.

In Guelph and Rockwood, power interruptions can be caused by problems on overhead lines, underground cables, transformer stations or on individual homes.

When a power outage occurs in Guelph or Rockwood, our Supervisory Control and Data Acquisition System (SCADA) provides notification to our Network Control Centre so we can quickly identify the outage.

In many cases, automatic switches reroute power to minimize outages. Remotely operable switches enable our system operators to restore power from our Control Centre without even leaving Guelph Hydro's operation.

If power cannot be restored remotely, repairs are handled efficiently, in even the worst weather conditions, by our highly skilled emergency repair crews who are on call 24 hours a day, 365 days a year.

During widespread power outages, we work to restore power in phases, making sure critical community services are restored first.

  • Phase 1 - Restoration of critical infrastructure such as hospitals, water and waste treatment plants.
  • Phase 2 - Restoration of community infrastructure such as community centres, locations of emergency serves and other important locations.
  • Phase 3 - Restoration of as many large groups of customers as possible by neighbourhood or streets.
  • Phase 4 - Restoration of individual homes and businesses.

Reporting a Power Outage

If you wish to report a power outage, please call our Power Outage Line at 519.822.3014.

Please bear in mind, however, that a power outage can impact thousands of customers so the possibility of getting through may be limited. Please be assured that we will be making every effort to restore services.

In the event of a widespread outage, please be patient and listen to local radio stations, view our Power Outage Map for current outages or follow our Twitter stream (@guelphhydro) for updates.

Storm Damage to Your Home

Severe weather can cause damage to electrical equipment attached to your home such as the masts and pipes. This equipment belongs to the homeowner and will need to be repaired to make it safe before Guelph Hydro can
restore service.
