What happened
An electrical fire at Blue Hills Power Station in New Providence, Bahamas, caused a complete loss of power across the island in the early hours of the morning. Bahamas Power and Light (BPL) reported that preliminary investigations indicated a suspected underground cable fault had caused the explosion of a 15MVA transformer at the station, triggering the island-wide outage. The fire was extinguished and repair crews began restoring supply in stages to protect grid stability and safety.
Within a few hours BPL reported that approximately 50 percent of customers on New Providence had power restored, with teams continuing work to reconnect remaining areas. No injuries, fatalities or evacuations were reported in the source material.
Contributing factors
BPL stated that preliminary findings pointed to a suspected underground cable fault as the cause of the transformer explosion; this is described as a preliminary finding pending further investigation.
Lessons learned
- A suspected underground cable fault triggered explosion of a 15MVA transformer, so operators should improve cable fault detection and monitoring at substations.
- After a major transformer failure, supply must be restored in stages to protect grid stability, as crews did once the fire was out.
