Georgia Power, a utility company headquartered in Atlanta, said on Sunday it expected to have electricity restored in the city's international airport by midnight.

"Georgia Power continues to work closely with Hartsfield-Jackson International Airport personnel onsite to restore power to the Airport as quickly as possible. Assessment and repair efforts are well underway at this time and the company expects to have power restored to the Airport by midnight tonight," the company said in a notice posted on Twitter.

A power outage earlier on Sunday left travelers stranded on the runway and in the terminals of the airport, which is one of the busiest in the world.
