Officials said around 7:45 p.m. that power had been restored to at least one concourse at Hartsfield-Jackson Atlanta International Airport.
On its Twitter page Sunday night the airport tweeted, "Power on Concourse F is back ON! We are working with great urgency w/ @GeorgiaPower to restore power throughout rest of airport."
Power had been out at the airport since about 1 p.m. All flights coming into and going out of the airport were halted.

Officials said the airport is also diverting international flights.
