What happened

A news headline dated 18 December 2017 said an airport blackout had been pinpointed to switchgear at a substation. The available report does not name the airport, the town, the operator or the failed equipment, and it does not say how long the outage lasted or whether anyone was hurt.

Contributing factors

Not reported. The headline attributes the blackout to substation switchgear but gives no cause.

Lessons learned

A fault in substation switchgear can cut supply to a critical site such as an airport.
Operators of critical loads should know which substation equipment their supply depends on.
