Lessons learned

  1. A reported equipment fault at a substation can escalate into a fire that needs a large fire service response.
  2. Operators should be ready to isolate plant and give firefighters clear site information.
  3. Early reports may not establish the failed component or customer impact, so those points should stay unconfirmed until further sources appear.
