What happened

A fire at an electrical substation in Jeffersontown knocked out power to nearly 5,000 LG&E customers. The fire was reported around 5 p.m. on 17 May 2019 near Taylorsville and Ramblin Creek roads and was reportedly caused by a damaged transformer. LG&E estimated that power would be restored around 12:30 p.m. Taylorsville Road was closed briefly during the response.

Contributing factors

A damaged transformer was reported as the cause of the fire. No further detail on how the transformer was damaged has been reported.

Lessons learned

  1. A damaged transformer at a distribution substation can interrupt supply to thousands of customers.
  2. Operators should treat published restoration times as estimates until supply is confirmed back.
  3. Access near the site may need a short closure while crews investigate.
