NextEra Energy : Irma Knocks Out Power to 3.5 Million Customers in Florida

Hurricane Irma knocked out power to about 3.5 million customers in Florida as of Sunday evening, according to outage maps from the state's utilities, which warned that some people may not regain electricity for weeks, despite billions of dollars in investments to strengthen the power grid in recent years.

While Irma's path has shifted west, Rob Gould, a vice president for Florida Power & Light Co., a subsidiary of NextEra Energy Inc., cautioned customers on the state's east coast to remain vigilant about downed power lines, the fact their power might still go out and safety issues with home generators.

"Let me be perfectly clear: Do not let your guard down, do not become complacent," Mr. Gould said during a Sunday news conference -- which was briefly interrupted because of a loss of power. "This is a very powerful storm and every bit of Florida is going to feel its wrath."

FPL, the state's largest investor-owned utility, serves nearly five million customers.

Tampa Electric, a unit of Emera Inc., estimated that Irma's shift westward could cause as many as 500,000 of its customers to lose power, which would be up to 70% of its system.

Florida utilities have warned that Irma's strength could cause heavy damage to the electric systems, and some repairs could take weeks.

Duke Energy Corp., the state's second-largest utility, has estimated it could see more than one million outages because of Irma. The company serves about 1.8 million customers in Florida.

"We expect significant power outages and restoration in some areas could take a week or longer," Luis Ordaz, storm director for Duke Energy Florida, said Sunday.

The gigantic storm covers an area more than double the size of the state and on Sunday had maximum sustained winds of 110 miles an hour.

FPL said Sunday that it had partially shut down its Turkey Point nuclear power plant in Homestead, about 25 miles south of Miami, but its St. Lucie nuclear plant in Jensen Beach, near Fort Pierce, continued to be fully operational and remained safe.

The company and its power-providing peers in Florida have spent billions of dollars over the last several years upgrading their technology and infrastructure to better handle storms.

FPL has spent $3 billion since its system was slammed by seven hurricanes in 2004 and 2005. Improvements include replacing wooden poles and transmission structures with concrete ones, installing real-time water monitors to alert the utility to flooding at 223 substations susceptible to storm surge, using smart meters to identify outages more quickly and automated switching technology to reroute around trouble spots.

Duke has spent more than $2.4 billion on similar upgrades since 2004, including using "self-healing" systems to reroute power.

The improvements, utility representatives said, are designed not to prevent outages wholesale, but rather limit damage so that it is easier to restore lost power more quickly. But given Irma's size and strength, the companies were preparing for the worst.

"We estimate millions of customers will lose power as a result of Irma," Mr. Gould, the FPL spokesman, said Sunday, adding that crews likely need to set up hundreds of new poles and string thousands of miles of new line. "A storm of this magnitude an intensity will require us in many cases to completely rebuild out electric system from the ground up, particularly on the west coast. We anticipate that restoration effort will be measured in weeks, not days."

All the utility companies were mustering thousands of employees -- including workers from utilities from more than two dozen states -- to be ready to repair outages in Irma's wake.

Florida Light & Power said it had nearly 17,000 restoration workers positioned across Florida. Duke had mobilized roughly 8,000, including 1,500 from its own Midwest operations, while Tampa Electric had called in nearly 6,000 workers.

Bonnie Erdek, a spokeswoman for Florida Public Utilities Co., a unit of Chesapeake Utilities Corp., said her company has been having storm calls twice a day to prepare for Irma. It serves about 120,000 customers, and hadn't experienced any outages as of Sunday morning.

"In South Florida, we are just standing by," Ms. Erdek said Friday. "We're bringing in linemen, many of whom just left Texas."

At Gulf Power, a Southern Co. subsidiary that serves just over 455,000 customers in Northwest Florida, spokesman Rick DelaHaya said the company was also keeping an eye on the storm in case it shifts closer to the Gulf.
