How we restore power

Our restoration process, prioritization and responsibilities.

The power can go out for many reasons, including severe weather, equipment failures and animal contact. Sometimes an outage lasts only a few minutes, while other times an outage can go on for an extended period of time.

Our crews work around the clock to restore power as quickly and safely as possible.

Restoration process

Once an outage has been reported, we follow these steps for power restoration:

  1. Our trucks are dispatched

    Crews drive to outage sites on the same roads the rest of us do. That means that heavy traffic can slow them down.

  2. We assess the damage

    It may take time to determine the exact location of the problem, especially when dealing with underground equipment. Repairs can’t be made until the cause is determined.

  3. We make the repairs

    While we do our best to provide restoration times, it’s not always possible to do so.

  4. We test the repairs

    Crews make sure that the problem has been resolved and power can be restored.

  5. Power is restored

    We restore power to all affected customers.

Following an outage, remember to:

  • Reset electric clocks, timers and alarms
  • Restock your emergency kit so it's ready if needed again

Prioritization process

When there are multiple outages across the city, we must prioritize our work in specific areas.

Critical services
We restore outages that are most critical to public safety first. These include hospitals, fire, police and essential citywide systems.
Stations and feeder lines
After restoring critical services, we make repairs to stations or major feeder lines that serve the largest number of customers.
Individual homes
Finally, we restore power to smaller neighbourhoods, streets and individual homes or businesses.

Estimated Time of Restoration (ETR)

We do our best to keep our customers updated during outages, but providing ETRs isn’t always possible. Each outage is unique and a lot of variables can affect repair efforts, especially during widespread outages.
