Centurion power supply fully restored after gruelling repairs, says metro
Power supply has been restored to all parts of Centurion previously affected by the explosion at the Zwartkop Substation on May 20, according to Tshwane metro spokesperson Lindela Mashigo. The incident involved the explosion of Transformer 1A at the substation, which resulted in widespread outages across multiple areas, with some residents enduring more than a week without electricity. Mashigo said the restoration comes after a gruelling eight-day repair process. Zwartkop Substation fully operational. — City of Tshwane (@CityTshwane) May 28, 2025 'The city's energy and electricity technicians worked around the clock through a strenuous cable installation and connection process,' he said. He stated that once that process was complete, the team had to undertake the complex task of modifying the Cable End Box, which serves as the connection point between the cables and the main transformer. 'This task was complicated by the fact that the end box's original components were manufactured in 1972. 'Some of the parts had to be imported from other countries to complete the modification,' said Mashigo. He encouraged any residents who may still be without power to report the issue through the city's normal complaint logging channels. Mashigo expressed appreciation for the patience, co-operation and understanding shown by affected residents during the extended outage and apologised for the inconvenience caused. Before the full restoration, the metro had already managed to restore electricity to some areas. On May 21, MMC for Utility Services Frans Boshielo explained that the explosion had also tripped the Lyttelton Line 1 at Njala, affecting electricity supply to parts of the network served by the Wingate, Aries, and De Hoewes substations. At the time, he stated that technicians were able to stabilise those lines and successfully restore supply to the affected zones. However, other areas, including Zwartkop, Valhalla, Clubview, parts of Claudius, the military base in Thaba Tshwane, and the Zwartkop Airbase, remained without electricity.

Power supply restored to parts of Centurion after substation explosion
Power supply restored to parts of Centurion after substation explosion While several areas in Centurion remain in the dark after a substation explosion on May 19, the Tshwane metro has managed to restore supply to some areas. The incident, which occurred around 05:50 on Monday, involved the explosion of Transformer 1A at the Zwartkop Substation, leading to a power outage across multiple areas. MMC for Utility Services Frans Boshielo confirmed that the explosion also caused a trip on the Lyttelton Line 1 at Njala, initially cutting off Wingate, Aries, and De Hoewes substations' supply. Boshielo said that the supply has since been successfully restored to those three areas. However, residents in Zwartkop, Valhalla, parts of Claudius, Clubview, the Military Base in Thaba Tshwane, and the Zwartkop Airbase remain without electricity. He said the metro's Energy and Electricity Department continues with restoration efforts in these areas. 'The teams are working tirelessly to restore supply to all affected consumers as swiftly and safely as possible,' he said. The current work to restore power to the affected areas is extensive. Boshielo said the process involves testing of Transformer 2B, oil sample analysis sent to a laboratory, and the replacement of damaged infrastructure, including 630mm high-tension cables and crucial control cables required for the substation's protection grading. 'Full transformer protection tests are also being carried out to ensure operational safety of the transformer and proper protection grading of the substation.' He noted that repairs on the Lyttelton/Kwagga Overhead Line 1, which was also damaged by fire, are scheduled to begin on May 20. 'I would like to extend our appreciation to all residents and businesses for their patience, co-operation, and understanding during this time,' said Boshielo. He added that the metro team will provide updates every day at 19:00. Tshwane spokesperson Selby Bokaba said that the destruction of the 630mm high-tension cables and essential control cables has significantly complicated the repair efforts. 'These control cables are essential for the protection of the substation,' said Bokaba. He emphasised that the fire damage to the Lyttelton/Kwagga Overhead Line 1 necessitated the disconnection of the line by the sub-transmission team. Bokaba provided a cautiously optimistic outlook, stating that overnight work yielded positive results. 'Transformer 2B test results have tested positive and are ready to be used,' he said. He stated that the next step in the process will involve replacing the stolen single cores and multicores for Transformer 2B. Despite these advances, he stressed that the estimated time for full power restoration will only be communicated once the majority of the repair work is completed.
