Transformer fire at Piti substation isolated with no reported injuries

A transformer at Guam Power Authority's Piti substation caught fire on a Friday afternoon in August 2017. Smoke and flames were visible rising from the substation. GPA crews isolated the affected area. According to a GPA spokesperson, there was no harm or danger to life or property, and the utility did not believe any customers were affected by the fire. Separately on the same afternoon, a feeder line tripped in the Yigo area; this issue was also isolated and addressed by GPA crews. Customers experiencing power quality issues were advised to contact GPA's trouble dispatch line. No further details on the cause of the transformer fire, damage extent, or repair timeline were reported.

Not reported.

1. Rapid isolation of a faulted transformer can prevent escalation and limit or avoid customer outages.
2. Clear public communication immediately following an incident, including reassurance on safety and customer impact, helps manage public concern.
3. Maintaining a dedicated trouble dispatch line allows affected customers to report power quality issues promptly, aiding utility response.
