Widespread outage; city started own power plant

A piece of equipment failed and sparked a fire late on a Wednesday night in June 2018 at the Hypoluxo substation, causing a widespread power outage in Lake Worth. The city manager said the item that failed was a replacement installed after a transformer malfunctioned in April and was sent away for forensic testing, and that there was no data yet on the cause of the latest failure. Residents were without power in high temperatures. He said failures of this kind affected the city's only incoming supply line, after which it takes several hours to start the city's own power plant.

The city manager described an ageing system, a backlog of problems and years of under-investment, but said the cause of this failure was not known. The city has only one incoming supply line.

  1. Do not treat the cause as known until testing of the failed item is complete, including when a replacement fails.
  2. A single incoming supply can turn a local equipment failure into a wider outage lasting several hours.
  3. Sections that fail more often, and deferred renewal, should be identified and funded before the next outage, not only after repeated events.
