An electric substation at the corner of West and Victoria streets in Pietermaritzburg exploded shortly before noon on 9 October 2025, and parts of the city lost power. The fire had already burned out when Msunduzi firefighters arrived, but smoke was still coming from the structure. Firefighters struggled to open the metal doors and used the jaws of life to force them open so they could assess the damage. A person at a nearby business said the power had gone out shortly before the explosion and that it was unclear whether the two were connected.

A local councillor said residents and businesses near the substation should expect intermittent or no electricity, advised alternative arrangements for essential services while repairs were under way, and asked people to avoid the area and use other routes.

The cause was not reported. A person at a nearby business said the substation had not had problems for some time, and speculated that difficulty opening the doors might mean maintenance was not being done properly. That view is not confirmed.

  1. Substation doors and other access points should be kept workable so emergency crews can enter quickly.
  2. Operators should check doors and entry mechanisms during routine inspections.
  3. During an outage, operators and the local authority should tell nearby residents and businesses what is known and what is still unclear.
