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

A structure fire broke out at an electrical substation operated by AEP Texas in San Angelo, Texas. Emergency services attended the scene and witnesses reported a loud fiery explosion coming from the substation as it burned. AEP Texas staff were seen using fire extinguishers and disconnecting the substation from nearby power lines to isolate the fault. Roads adjacent to the site were closed to allow first responders access. Thousands of customers in the surrounding area were reported without power around the same time, though it was not confirmed whether this outage was directly caused by the substation fire.

A nearby school was placed on a precautionary safety hold while emergency crews responded, although it was not confirmed whether this was directly linked to the substation fire. No injuries were reported at the time of the initial reporting, and the cause of the fire had not been determined.

Not reported.

  1. Substation fires can escalate to explosive failure, so operators must isolate the site from the network at the first sign of fire.
  2. Road closures and emergency access plans must be ready for substation fires to protect nearby roads and facilities.
