The Puerto Rico Electric Power Authority is out of service and isn't providing any power across Puerto Rico right now, its CEO told CNBC on Friday.
The company, the U.S. territory's main electrical provider, has been "devastated by Hurricane Maria," Ricardo Ramos said in an interview with "Closing Bell."
Power went down across the entire island after Hurricane Maria made landfall as a Category 4 storm early Wednesday. It was the most powerful storm to hit Puerto Rico in 90 years.
Ramos is hoping to get power fully restored quicker than the six months it took after Hurricane Hugo hit in 1969.
"It's a step-by-step process," he said. "We hope ... three to four months at most."
