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

A viewer submitted dashcam video to KSAT Connect, the submission platform of the San Antonio news outlet KSAT, which appears to show a transformer exploding on the Northwest Side of San Antonio, Texas. The footage shows the road lit up as drivers passed. The video was uploaded just before 9:30 p.m. on Monday, and the reported location was the Interstate 10 frontage road at Wurzbach Road. As of the following Tuesday morning, KSAT reported no power outages in the area, according to the CPS Energy outage map.

KSAT said it had asked CPS Energy for further information. The source does not confirm the owner of the equipment, the cause of the event, or any damage or injuries.

Not reported. The source describes the event only from a dashcam recording and does not state a cause.

  1. Transformer failures can be visible to the public at night, so operators should check for public reports and dashcam footage soon after an event.
  2. Where a failure causes no customer outage, operators should still confirm equipment condition, since the fault may be progressing.
  3. Operators should publish or confirm to local media the status of incidents on public roads to reduce confusion and reassure road users.
