"Access to electricity can be a lifeline in a disaster and our crews are determined to help restore power to the families and businesses in Florida as quickly and safely as possible", Greg Kiraly, Chief Operating Officer of Hydro One, said in a statement on Monday.
Before and after photos from the National Oceanic and Atmospheric Administration compared the lights on a typical night in the Sunshine State to the drastic loss of light after the storm plowed through the state.
FPL said on Tuesday it planned to restore power to eastern Florida by this weekend and to western Florida by September 22.
There are roughly 7 million residential customers in the state.
Floridians who weathered the historic storm must now cope with an unprecedented loss of power: About 15 million people were without electricity across the state, the Department of Homeland Security said Tuesday.
The Irma blackout is still much smaller than a 2003 outage that put 50 million people in the dark.
FPL is the third-largest US electric utility, serving almost 10 million people in the southern half of Florida, CBS Miami reported.
One of the many rumors circulating as Hurricane Irma draws closer to South Florida is that residents will lose power once FPL shuts down the Turkey Point nuclear plant ahead of the storm.
Help is coming from as far away as Canada.
Some of the outages from the hurricane could end up lasting for a long time, especially if the energy infrastructure needs to be rebuilt in order for power to get restored, according to the institute.
In Houston, about 4,000 customers were without power as many of those homes remained flooded due to water releases from two reservoirs that were filled by Harvey's torrential rainfall.
In South Carolina, about 55,000 customers were without power, according to Duke Energy and SCE&G.
"A lot of times, we come on these storms and people get really hostile as far as not really understanding why we can't just flip a light switch and make everything come back on", Parker said. Another 65% suffered major damage. "I cooked a frozen pizza because it was about to go bad", he said, referring to his experience during Wilma. "The minor damage we sustained".
Most of those costs were related to Matthew, which caused a third as many outages as Irma did for FPL.
