The Brief<\/p>\n

Duke Energy crews replaced underground cables in downtown St. Petersburg on Wednesday as part of a proactive maintenance.<\/p>\n

The specialized, submersible system features a huge network of transformers and cables that are capable of automatically rerouting power during a failure to prevent widespread outages.<\/p>\n

The technology is in only two locations across Duke Energy’s 35-county Florida service territory: downtown St. Petersburg and downtown Clearwater.<\/p>\n

ST. PETERSBURG, Fla. – Deep beneath the bustling streets of downtown St. Petersburg<\/a>, a massive network of specialized electrical equipment ensures continuous power for the city.<\/p>\n

Duke Energy upgrades downtown St. Petersburg<\/p>\n

What we know<\/p>\n

Duke Energy<\/a> crews swarmed the area Wednesday to replace aging cables with new ones as a proactive measure.<\/p>\n

\"<div>Thick<\/p>\n

Thick insulated power cables are fed directly into an underground utility access point beneath the city streets.<\/p>\n

“The system kind of self-heals itself,” Torean Savage, a network specialist with Duke Energy, said. “So, if one place goes out of power, there’s another transformer and cables making up for that power, preventing outages or kind of fixing the outage at a faster rate of speed.”<\/p>\n

While some above-ground lines have this self-healing technology too, the big deal with this network is it\u2019s protected from the elements and won\u2019t get corroded by water.<\/p>\n

Grid reliability history<\/p>\n

The backstory<\/p>\n

The network has been in downtown St. Pete since the 1950s<\/a>, replacing the traditional above-ground power lines that have to be a certain distance from public spaces for safety purposes. That\u2019s clearance that downtown St. Pete and many other cities don\u2019t have.<\/p>\n

\"<div>Traditional<\/p>\n

Traditional overhead power lines stretch across a utility pole, illustrating the older style of electrical distribution that requires public clearance.<\/p>\n

About half of Duke Energy\u2019s power lines across Florida <\/a>are underground, and the other half are overhead. Normal underground power lines, though, are different than this network. They can\u2019t get wet and still work, while this submersible system can.<\/p>\n

Weatherproofing local communities<\/p>\n

What they’re saying<\/p>\n

“It\u2019s definitely a game-changer. Like I said, if you’ve been around for these hurricanes and storms going around, it definitely helps with the reliability,” Savage said.<\/p>\n

\"<div>A<\/p>\n

A Duke Energy utility vehicle stands ready on a city street with a massive spool of heavy-duty electrical cable during infrastructure upgrades.<\/p>\n

The technology is only in two places, downtown St. Pete and downtown Clearwater, out of the company\u2019s 35-county territory.<\/p>\n

“We have hospitals here. We have the airport right here, government buildings. We want to make sure those places are protected,” Savage said.<\/p>\n

Expanding the grid<\/p>\n

What’s next<\/p>\n

Savage says that the company hopes to expand this type of network to other areas.<\/p>\n
