City Power has reported an unplanned electricity interruption at Ennerdale Substation affecting customers in parts of Ennerdale, Johannesburg. Its statement, published on 16 October at 19:33 SAST, says operators have been notified and will be dispatched to investigate.

Status of this incident

Power outage confirmed

Last known status: confirmed by the source · 16 October, 19:33 SAST: City Power reports an unplanned interruption in parts of Ennerdale; investigation dispatch planned, restoration time unknown.

Source moment: 16 Oct 2026, 17:33 UTC (19:33 local time)

In 20 seconds

  1. The operator names parts of Ennerdale, without identifying affected streets or a customer total.

  2. Operators are to be dispatched to investigate; their arrival is not confirmed in the notice.

  3. The statement gives no exact start time, cause or estimate for electricity to return.

What City Power reported on 16 October

The operator’s notice describes an unplanned power interruption at Ennerdale Substation. It limits the reported impact to customers in parts of Ennerdale. That wording does not establish that every home in Ennerdale, or the wider Johannesburg area, has lost electricity. No customer total or detailed street boundary accompanies the verified statement.

The publication time is 19:33 SAST on 16 October, corresponding to 17:33 UTC. It records when City Power issued the notice, rather than when electricity first went off. The exact onset remains unknown, so the time of the statement cannot be used to calculate how long customers have been without supply.

What the sources tell us, and what they do not

Reported area
Parts of Ennerdale; Ennerdale Substation, Johannesburg
Operator response
Operators notified; dispatch to investigate planned
Affected customers
Count unknown
Restoration estimate
Unknown; cause and exact onset also unknown

Investigation planned; restoration estimate unknown

City Power says operators have been notified and will be dispatched to investigate the cause. This describes a planned response. It does not confirm that a crew has arrived, that an investigation is complete or that repairs have begun. The checked statement does not identify a failed component or provide a restoration deadline.

The relationship to the older Lawley 1 and Ennerdale Extension 9 interruption reported on 12 October remains unresolved. A shared substation name does not establish continuity or a separate technical fault. This report covers the 16 October notice without treating it as proof of a continuous four-day outage or a confirmed recurrence.

Planning for an interruption of uncertain length

The outage essentials guide provides general preparation advice. The runtime calculator helps estimate how long essential devices might run from a battery. These resources support household planning; they cannot determine whether an individual address is affected or predict when supply will return in Ennerdale.
