The man was conscious when workers reached him, according to WPLG. He suffered third-degree burns to 60% of his body, plus exit wounds from the shock, authorities told the television station.
Officials from Florida Power and Light said the man was not a power worker, WSVN reported.
John Moore, who works at a nearby gas station, told WPLG there was a power outage and a loud noise when the man was shocked.
"I don't know how you survive falling that far by itself," Moore told the television station. "I don't know how you survive getting shocked like that. Either one of those is very fortunate."
