Frikkie Substation Repairs Face Extended Timelines After Severe Damage

Repairs to the Frikkie Substation in Merafong City are expected to take longer than initially planned after technical teams uncovered more extensive damage to its infrastructure. A diagnostic assessment carried out on 16 September 2025 showed that the 5 MVA transformer had suffered greater internal damage than first anticipated.

Originally estimated at three to five days for restoration, the timeline has now been extended to allow for more comprehensive intervention. The manufacturer has scheduled delivery of the repaired unit for 24 September 2025, with the aim of reducing the risk of recurring faults and ensuring long-term reliability.

10 MVA Transformer Sent for Analysis

In addition to the 5 MVA transformer, the 10 MVA unit was removed from the site and transported to the manufacturer’s facility on 16 September. Fault analysis began the following day, focusing on identifying the root cause of the breakdown, measuring the extent of the damage, and establishing realistic repair and recommissioning deadlines.

This development means that both transformers critical to the substation’s operations are undergoing significant inspection and repair, a process that could delay full power stability in the affected areas.

Impact on Residents and Way Forward

The ongoing setbacks underline the challenges municipalities face in maintaining aging electrical infrastructure. While the immediate inconvenience to residents is evident, officials have emphasized that prioritising detailed repairs and diagnostics is crucial to prevent repeated failures in the future.

Further updates are expected as the repair processes continue, with clearer timelines likely once the manufacturer’s assessments are finalized.
