More than 6.7 million Florida homes and businesses are now without power after Hurricane Irma moved through the state, according to the state's emergency management division.
Everybody FPL has available is "already being deployed" and the company is trying to secure more workers from out of state to help, Silagy said, including some crews who were assisting in Texas after Hurricane Harvey.
Sunday night, 31 utility workers were stationed waiting out the storm in Orlando at Florida Power and Light's staging area.
Irma hit southwestern Florida on Sunday morning as a unsafe Category 4 storm, the second-highest level on the five-notch Saffir-Simpson scale.
In all, nearly 1.8 million FPL homes and businesses had lost power.
Still, he said, it will take days for many people to be restored and, in some cases where the damage was extensive, weeks.
Georgia reported more than 570,000 homes and businesses without electricity, and there were 80,000 in SC.
As of Sunday morning, almost 1.1 million customers across Florida did not have power, Florida Power & Light Company said, according to The Associated Press.
FPL said it expects to restore essentially all of its customers in the eastern portion of the state by the weekend and the harder-hit western portion Florida by September 22.
In Miami-Dade County, there were about 574,000 outages, according to the AP.
They plan to spend the next two weeks working to restore power to millions affected by Hurricane Irma. He believes southwest Florida is the most impacted but cautions that numbers may rise as "Irma hasn't left". FPL, a unit of NextEra Energy Inc and the state's biggest power company, said its outages dipped below 2.8 million by Tuesday afternoon from a peak of over 3.6 million Monday morning.
Most of those costs were related to Matthew, which caused a third as many outages as Irma did for FPL. FPL reduced power at one reactor at the St. Lucie nuclear plant due to salt buildup in a switchyard from Irma. On Sunday, Gould said its nuclear plants were safe.
