Outage History

Have you recently experienced a power outage? Search the outage history to learn more about the power interruption.

Information on outages that have occurred within the last 30 days is available. This map does not include momentary outages, also known as ‘auto-reclosures’. This is when a Hydro Ottawa circuit breaker at a substation opens momentarily to allow a temporary fault or problem on the distribution system to clear (e.g. lightning strike or tree branch contact). The circuit breaker then "auto-recloses" to restore power thus avoiding a prolonged power outage or the dispatch of field personnel to restore power.

Information on current outages is also available.
