The crowd in the atrium at Hartsfield-Jackson International Airport erupted with cheers when power came on after a 10-hour outage.
The airport atrium, Concourses T, A, and B and terminals were passengers check in and retrieve baggage powered up at roughly 11:20 p.m. Concourse F had been brought back online earlier in the evening.
Mayor Kasim Reed announced shortly before midnight that the entire airport had been fully restored.
The outage was caused by a fire between 12:30 and 12:45 p.m. The intensity of the power also took out a back-up system, and Georgia Power workers were delayed from addressing the issues for hours.
