Companies named in the reporting of this entry (being named is not a finding of fault): SDG&E

An estimated 673 customers across Coronado Village, California, lost power on Monday night, with the outage affecting the northern and western parts of the neighbourhood. By a 9:30 p.m. update most had their power back, but roughly 280 residences remained without electricity. San Diego Gas & Electric (SDG&E) estimated that power would be fully restored by 10:30 p.m. Police, fire officials and SDG&E crews attended the area near Sixth Street and Alameda Boulevard to investigate.

Coronado police said the cause was unknown but could involve a faulty underground transformer. As of the last update, no cause had been confirmed. The report also referred to earlier outages in Coronado, which involved different causes, scales and locations and which the reporting does not tie together as a broader trend.

No cause had been confirmed at the time of the last update. Police said the cause was unknown but could involve a faulty underground transformer.

  1. Where the cause of an outage is unknown, utilities and police should publish the failed component once it is confirmed, so the public record reflects the actual fault.
  2. Restoration estimates should be updated publicly as the picture changes, since the estimate for an earlier Coronado outage slipped from 3 p.m. to around 7 p.m. the same day.
  3. Repeated outages in the same area warrant an asset history review, even where the reporting finds no common cause.
