What happened
An explosion occurred at one of the main electricity substations serving Roodepoort, west of Johannesburg, on a Thursday in late March 2026. The event affected several substations across a large area, leaving multiple suburbs without power. City Power, the municipal electricity utility, said technicians were sent to the site to investigate the cause of the disruption. The utility stated that most restoration work would be carried out overnight and into the following morning so that power could be returned to affected residents. No cause had been confirmed at the time of reporting, and the utility did not disclose details on injuries, damage extent or the specific substation involved.
