Power has been restored to Terminal 1 at Lambert St. Louis International Airport.
According to the airport, the outage began around 11:30 a.m. in the terminal after a blown transformer was reported.
“Emergency power was utilized immediately for health, safety and critical building operations. However, the outage caused issues with baggage delivery systems, airline computer stations and some gate operations,” the airport said in a blog post Sunday.
Power was restored at 5 p.m.
Ten flights were canceled because of the outage and several more were delayed. Some airport functions relying on electricity, like check-ins and security screenings, were done manually.
