On 19 April 2018 a transformer caught fire at an electrical substation on Lower Campus Road at the University of Hawaii at Manoa. The Honolulu Fire Department responded at 6:47 p.m. Thick black smoke rose over Honolulu. The department later ruled the fire accidental and said a malfunction inside the transformer ignited the oil. Damage was estimated at $1.5 million. Injuries, outages and downtime were not reported.

The fire department reported that a malfunction within the transformer ignited the oil inside. No other contributing factors were reported.

  1. A malfunction in an oil-filled transformer can ignite the oil and create a large smoke plume.
  2. Campus substations need clear access routes so fire crews can reach equipment fast.
