Ingram Publishing/Thinkstock(ATLANTA) — At least some flights at Atlanta’s busiest airport have been grounded due to a power outage.

Hartsfield-Jackson Atlanta International Airport suffered a power outage at around 1:30 p.m. Sunday. The airport, Atlanta Fire and Rescue officials and Georgia Power staff are on the scene to respond and restore service, a spokesman told ABC News.

It’s unclear how widespread the outage is or what caused it.

The airport tweeted that the outage had “impacted several areas in the airport” and that officials were “working to remedy the situation.”

The FAA confirmed to ABC News that it grounded any flights headed to the airport “due to the power outage” but also said that the airport’s tower has power and is capable of operating “normally.”

Delays should be expected with the equipment failure at several terminals, the FAA official added.

A representative of Delta Airlines, which uses the airport as a central hub, stated that “diversions are in progress” for flights that were already in the air and headed to Atlanta.

The airline representative told ABC News that there are jets sitting on the tarmac waiting to taxi to various gates.

Hartsfield-Jackson International Airport sends jets to 150 domestic destinations and more than 75 international destinations in 50 countries.

It is one of the busiest airports in the world with 275,000 passengers on average passing through its terminals every day and with about 2,500 flights arriving and departing.
