Companies named in the reporting of this entry (being named is not a finding of fault): City of Tshwane

On 17 August 2024, volunteer responders reported an explosion at Nyala Substation on Delmas Road in Pretoria East. They found a burning transformer, set up a safety area, and called City of Tshwane firefighters. Crews then set up an inline foam system and used foam on the fire. City of Tshwane electrical technicians took over the scene to assess the damage, and Tshwane Metro Police also attended. The cause, any injuries, and any effect on supply were not reported.

The cause was not reported. The only detail given is that a transformer was burning after the explosion.

  1. Treat a reported substation explosion as a live fire until the scene is assessed, and keep a safety area until the operator takes over.
  2. A burning transformer may need foam, so tell the fire service what resources are required before crews arrive.
  3. Hand the scene to the network operator for damage assessment, and do not treat the cause as known until that investigation is reported.
