Drive about 25 miles south of Miami, past the sprawling suburbs and the last bits of strip malls, and you’ll hit something most people try to avoid thinking about. It's a massive complex sitting right on the edge of Biscayne Bay. This is Turkey Point Nuclear Power. Most locals just know it as "the stacks," those iconic red-and-white striped towers that dominate the horizon. But there's a lot more going on there than just generating electricity. Honestly, it’s one of the most complex, debated, and frankly weird industrial sites in the United States.
It's huge.
Florida Power & Light (FPL) operates this behemoth, and it provides enough juice to power nearly a million homes. Without it, South Florida’s grid would basically fold under the weight of a million air conditioners running during a July heatwave. But it's also a place where nuclear physics meets the Everglades, which is about as high-stakes as it gets.
Why Turkey Point Nuclear Power is a Technical Weirdo
Most nuclear plants use massive cooling towers—those giant concrete hourglasses that spit out white steam. Turkey Point doesn't have them. Instead, it uses a 5,900-acre network of man-made canals. Think of it like a giant radiator sitting in the Florida sun.
There are about 168 miles of these canals. From an airplane, they look like a giant fingerprint etched into the coast. This system was designed in the 1970s because, at the time, it seemed like a brilliant way to avoid dumping hot water directly into the sensitive Biscayne Bay. It’s a closed-loop system, or at least it’s supposed to be.
But here’s the thing.
The water in those canals is incredibly salty. We're talking way saltier than the ocean. Because the water just sits there and evaporates in the Miami heat, the salt concentration builds up. This has created what experts call a "hypersaline plume." This heavy, salty water has been sinking and pushing out into the groundwater, which is a massive headache for local officials worried about the Biscayne Aquifer—the source of drinking water for millions. FPL has spent years and millions of dollars trying to manage this, pumping freshwater into the canals and pulling the salty water back out of the ground. It’s a constant battle against physics and geology.
The Units That Keep the Lights On
The site actually has several different power-generating units, not just nuclear ones.
✨ Don't miss: Wait, is there actually an iPhone 13 Pro Max pink? Let's clear up the confusion
- Units 1 and 2: These were the original oil/gas-fired units. They’re basically retired from the heavy lifting now.
- Units 3 and 4: These are the nuclear heavyweights. They are Pressurized Water Reactors (PWRs). Unit 3 started up in 1972, and Unit 4 followed in 1973.
- Unit 5: This is a much newer natural gas plant that joined the party in 2007.
The fact that Units 3 and 4 are still running is a testament to some serious engineering. They were originally licensed for 40 years. Then they got a 20-year extension. Then, in a move that made national headlines, the NRC (Nuclear Regulatory Commission) granted them another 20-year extension. That means Turkey Point is on track to operate for a staggering 80 years.
That’s unheard of. Or it was, until Turkey Point became the first in the nation to get that "Subsequent License Renewal."
The Crocodile Conundrum
You can't talk about Turkey Point without mentioning the crocodiles. It sounds like something out of a weird Florida news headline, but the cooling canals are actually a federally designated critical habitat for the American Crocodile (Crocodylus acutus).
It’s an accidental sanctuary.
While the rest of the Florida coast was being paved over for condos, the "no trespassing" signs at the power plant created a safe zone. The crocs love the warm, salty water and the elevated berms between the canals for nesting. FPL even employs specialists—actual croc biologists—to monitor the population. They tag the hatchlings and track their health. In the 1970s, these animals were on the brink of extinction. Today, the population is thriving, and a big chunk of that recovery happened right next to nuclear reactors.
It’s a bizarre irony. An industrial site that causes groundwater concerns is also the single most successful breeding ground for a threatened species. Nature is weird like that.

Safety, Hurricanes, and the Ghost of Andrew
If you live in Miami, you worry about hurricanes. If you live near a nuclear plant in Miami, you worry about them a lot more.
In 1992, Hurricane Andrew slammed directly into Turkey Point.
It was a nightmare scenario. The eye of a Category 5 storm passed right over the plant. The damage was extensive. The iconic smokestacks for the fossil fuel units were battered, and the site lost offsite power. But here’s the part that nuclear advocates always point to: the nuclear reactors themselves were fine. They were built to withstand 225 mph winds and a massive storm surge. The plant went into a safe shutdown, and the containment structures—those thick walls of steel-reinforced concrete—didn't flinch.
Since then, the safety protocols have only gotten tighter.
After the Fukushima disaster in Japan, the NRC required all U.S. plants to implement "FLEX" equipment. Basically, Turkey Point now has a hidden stash of backup pumps, generators, and even satellite communications gear stored in hardened buildings designed to survive the worst-case scenario. If the grid goes down and the primary backups fail, they have a "Plan C" ready to go.
The Controversy Over Expansion
For years, there was a massive push to build two more reactors—Units 6 and 7. FPL spent over $200 million just on the licensing process. They even got the green light from the federal government.
But then the economics shifted.

Fracking made natural gas incredibly cheap. Solar power started booming in Florida. Suddenly, spending $20 billion on new nuclear reactors didn't look like such a great deal for shareholders or ratepayers. In 2024, FPL essentially put those plans on ice. They haven’t officially killed the project, but they aren't building it anytime soon. Most industry insiders think those new reactors will never be built. The focus has shifted entirely to keeping the old units running safely and efficiently.
Addressing the Critics
Not everyone is a fan of keeping a 50-year-old nuclear plant running in a flood zone.
Groups like Miami Waterkeeper and various environmental advocates have been vocal. Their concerns aren't just about a "meltdown"—that's a Hollywood trope. The real concerns are more grounded:
- Sea Level Rise: Turkey Point is low. As the ocean rises, the "island" the plant sits on gets smaller. FPL insists the safety-related equipment is high enough to stay dry, but critics argue that the surrounding infrastructure (roads, power lines) is vulnerable.
- The Aquifer: That salt plume we talked about? It’s still there. Even with the remediation efforts, people worry that the "cleaning" process isn't fast enough.
- Nuclear Waste: Like every other nuclear plant in the U.S., Turkey Point stores its spent fuel on-site because the federal government still hasn't opened a permanent national repository. It sits in "dry casks"—massive concrete and steel cylinders. They are safe, but they are also permanent residents of the South Dade coastline for the foreseeable future.
What You Need to Know Moving Forward
Turkey Point Nuclear Power isn't going anywhere. With the license extensions, it’ll be part of the landscape until at least 2052. If you’re a resident or just interested in the energy future of the Southeast, here is the ground truth.
First, understand your power source. If you live in Miami-Dade, roughly 25% to 50% of your lights are powered by these atoms. It is the only reason Florida can even attempt to meet carbon reduction goals right now. You can’t replace two nuclear reactors with a few solar farms; you’d need thousands of acres of panels and massive batteries that don't quite exist at that scale yet.
Second, stay informed about the water. The Florida Department of Environmental Protection (FDEP) and Miami-Dade County track the salt plume. This isn't a "set it and forget it" situation. Local government pressure is what forced FPL to spend money on the recovery wells. Public oversight works.
Third, watch the weather. The real test for Turkey Point isn't the daily operation; it’s the next Andrew-level storm. The plant’s ability to maintain its cooling systems during a total regional blackout is the most critical safety metric.
Actionable Steps for the Curious
- Check the NRC Status: The Nuclear Regulatory Commission keeps a public "Current Performance" dashboard for Turkey Point. You can see if there have been any "scrams" (unplanned shutdowns) or safety violations in the last quarter.
- Monitor the Water Quality Reports: Miami-Dade County publishes annual reports on the status of the Biscayne Aquifer. If you're worried about the salt plume, that's where the raw data lives.
- Visit the Boardwalk: While you can’t just walk into the reactor core, the nearby Biscayne National Park offers a great view of the facility from the water. It puts the massive scale of the cooling canals into perspective.
- Understand the Bill: Look at your FPL bill. There are specific line items for nuclear cost recovery. It’s worth knowing exactly how much you’re paying for the maintenance of these aging giants.
The story of Turkey Point is really a story about trade-offs. We want carbon-free energy, but we have to deal with nuclear waste. We want to protect the Everglades, but we need the electricity that the plant provides. It’s a messy, complicated, and fascinating piece of Florida's infrastructure. It’s not perfect, but it’s essentially the heartbeat of the South Florida grid. Just keep an eye on those red-and-white stacks.
