Residents of several Johannesburg neighbourhoods face back-to-back power interruptions next week as City Power reschedules two separate maintenance jobs that were initially set for this week.
Alexandra SDC areas face a full day without power on Monday
Monday, 1 June 2026 has the longer and more disruptive of the two interruptions in Region E, Alexandra SDC.
An emergency maintenance job at Gresswold substation, originally scheduled for Monday, 25 May 2026, was pushed to the following Monday, with power cut from 9am through to 5pm.
The outage covers a wide band of northern and eastern suburbs, including:

As with the Sebenza work, City Power described the job as unavoidable network upkeep.
Residents in these areas are urged to plan around the full-day outage, particularly given that restoration could happen earlier than 5pm. “As the supply may be restored at any time, customers are urged to always treat their electricity supply points as live,” City Power said.
The utility added that it “regrets any inconvenience that may be caused by this interruption.”
Sebenza substation work pushes inner-city areas into darkness on Tuesday
