Lessons learned

1. A substation explosion can cause a wide outage and secondary fires, so operators should plan for loss of supply and for fire at electrical equipment.
2. Facilities that depend on power, such as care homes, should be identified in advance so that the network operator and emergency services can prioritise them during an outage.
3. Overheating switchgear and transformers should be detected early through thermal monitoring and routine inspection, and fire service liaison and isolation procedures should be agreed in advance.
