This map, updated every 15 minutes, includes information on power outages affecting 10 or more customers that reside within 200 metres of each other. Zones highlighted in the blue are planned outages to maintain or upgrade our infrastructure, while red zones are unexpected outages occurring across our service territory.

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.
