Substation damaged during reported copper theft attempt in St. Francis

On the morning of 14 March, St. Francis police were called to a We Energies substation on S. Kinnickinnic Avenue, just south of Howard Avenue, after a report of property damage. A We Energies employee told officers that someone had forced entry through the secure fence to steal copper and had tried to cut a live wire. Surveillance from a nearby recycling business showed an explosion at the substation and a person leaving on a bicycle about 20 minutes later. Tools and clothing were left behind. The employee estimated the damage at about $100,000. Whether the substation lost supply is not reported.

The complaint describes forced entry into a fenced substation to steal copper, and an attempt to cut a live wire. No independent technical finding on the cause of the explosion is reported.

1. Fenced substations remain targets for metal theft, so perimeter alarms and checks after forced entry should be treated as operational controls, not only security measures.
2. Live conductors inside a compound should be protected and clearly identified so that an intruder cannot easily reach them.
3. Operators should record damage, tools left behind and any supply impact promptly, because a single complaint estimate is not a confirmed loss figure.
