Lessons learned

1. Substation transformers are high-value single points of failure, so operators should assess transformer fire risk and the availability of spare units or temporary replacements.
2. A substation fire can cut supply across a wide area, so operators should plan backup supply routes and communicate outage areas and restoration status to the public promptly.
3. Cable faults and theft can prolong outages after a main fault is cleared, so security and cable protection should be considered as part of restoration planning.
