Fire guts Palm Ridge Substation control room, cutting power to thousands

What happened

A fire broke out on 3 July 2025 in the ripple control room of an electricity substation serving Palm Ridge and Sky City in Ekurhuleni, South Africa. The blaze damaged electrical breakers housed in the control room, cutting power to thousands of households and businesses. Ekurhuleni's Disaster and Emergency Management Services attended the fire. At the time of reporting, the cause of the fire had not been established and was under investigation by fire safety officers and city electrical engineers, with no confirmed timeline for restoring supply. Local businesses reported closures due to the extended outage, and residents expressed frustration over repeated infrastructure failures in the area.

Contributing factors

Residents alleged that widespread illegal electricity connections from nearby informal settlements, reportedly numbering over 1,500, place additional strain on the network, though the city had not confirmed this as the cause of this specific fire at the time of reporting.

Lessons learned

1. A fire in a ripple control room can damage breakers and cause long outages, so operators should fit early detection and automatic isolation in such rooms.
2. Illegal connections may overload substation equipment, so operators should inspect and remove unauthorised links where strain is reported.
3. Control room fire investigations must check both internal condition and external load factors before naming a root cause.
