By early Monday, around 450,000 Georgia Power and EMC customers mostly in coastal and south Georgia were without power after Irma crossed over into the state overnight, bringing high winds and rain.
Georgia Power reported 523,000 outages, and Georgia EMC, a trade group that represents electrical utility cooperatives, said nearly 321,000 homes and businesses were without power in its service areas.
Adrienne Tickle, a spokeswoman for the Atlanta utility, said Georgia Power dispatched crews to fix damaged power lines in the Atlanta area Monday morning, but recalled them to staging areas as the winds began to pick up.
About 3,400 personnel and crews standing by to respond to power outages after the storm leaves affected areas.
All of Georgia Power's resources are being held and dedicated to storm restoration efforts in the state following Hurricane Irma.
Crews are working around the clock to restore power.
A spokesman for Georgia EMCs released a similar statement.
Georgia EMC is the statewide trade association representing the state's 41 EMCs, Oglethorpe Power Corp., Georgia Transmission Corp. and Georgia System Operations Corp.
"As we go through today and tomorrow, we will have a better idea about the damage and the estimates". Georgia EMC customers can find more information on their website.
The utility reports it has served more than 30,000 customers since Sunday night in the wake of Irma, according to its outage map. The utility companies said they are continuing to assess damage as power is restored. "And as a result of that, recovery is going to be a little more slow because there are greater territories that have to be covered before anything can be back to a normal environment", Gov. Nathan Deal said Tuesday.
