Overview
- A blast at the Mayfair substation followed by a secondary explosion on Monday evening cut power to multiple Johannesburg suburbs and disrupted SABC transmission and Netcare Garden City Hospital operations.
- City Power reports repairs to the Mayfair site are about 95–98% complete and teams are finishing cable jointing and pre-commissioning tests before phased re-energisation.
- Engineers have energised a transformer at the Hesdale/Hursthill site to prioritise critical customers in the first phase, including the SABC, Sentech and Netcare Garden City Hospital.
- City Power says electrical feeds to local water reservoirs were maintained from the start of the outage, and testing delays were caused by unsatisfactory pre-commissioning results that required rework.
- Residents and businesses without supply will be reconnected in phases with City Power targeting first restorations by Sunday and full recovery by the end of the weekend, while longer-term Mayfair upgrades are planned over coming years.
