Substation fire and explosion during suspected cable theft in Campo Grande

What happened

In the early hours of Monday 5 February 2024, an explosion and fire occurred at an Energisa power substation in Vila Progresso, Campo Grande, Mato Grosso do Sul, Brazil. Residents reported the explosion at around 4:30 am. A man died at the scene. The main suspicion is that he broke into the substation entrance in an attempt to steal cables, causing a short circuit and flames. Firefighters attended and controlled the flames, and the Civil Police and experts were also on site.

Around 40 consumer units lost access to electricity. Energisa said the incident damaged substation equipment and interrupted supply, which was fully restored at 6:36 am. The incident remains under investigation by the competent authorities.

Contributing factors

Suspected attempted theft of cables, which is reported to have caused a short circuit. Suspected unauthorised access to the substation entrance, as the man who died is believed to have broken into it. Energisa states that warnings about the risk of high voltage wires and equipment are posted at the substation and in the surrounding area.

Lessons learned

1. Substations need physical perimeter security and intrusion detection, because cable theft at energised sites can cause short circuits, fire and outages.
2. Warning signage about high voltage hazards is not sufficient on its own and should be combined with barriers, lighting and monitoring.
3. Operators should publish the number of consumers affected and the restoration time so that the scale of an outage is clear to the public and to investigators.
