EIR-0721

Other entries that name Hillsborough

Provisional entry. Confirmed: a fire at a Tampa Electric substation in South Hillsborough County, Florida, with about 4,000 customers reported off supply; not yet known: the cause, the equipment involved, any injuries and how long restoration took. Next update: 16 September 2026.

A fire was reported at a TECO (Tampa Electric Company) substation in South Hillsborough County, Florida, with around 4,000 customers reported without power. Reporting available to the register is limited to a headline and summary, so the cause, the equipment involved, the extent of damage and the restoration time are not known. Injuries, if any, were not reported.

Not reported.

  1. A single substation fire can interrupt supply to thousands of customers, so operators should confirm backfeed and switching options for each distribution area.
  2. Early, clear outage communication helps affected customers and emergency services during substation events.
  3. Where early reporting is limited to customer numbers, operators should still capture equipment and cause data internally for later learning.
