Florida is growing, heating up and leaning harder than ever on a power system built around fossil gas and coastal transmission lines. If the state wants reliable electricity in the middle of stronger hurricanes and hotter summers, it will need a new backbone, not just more of the same. That is where small modular nuclear reactors move from abstract technology to a concrete plan that could shape Florida’s economic and environmental future.
Instead of a single mega-plant on the coast, the emerging strategy centers on compact reactors that can be built in factories, shipped by truck or rail and clustered where the grid needs them most. The political, regulatory and utility pieces for that shift are now being assembled in Tallahassee and at key power plant sites, and the choices Florida makes over the next few years will determine whether these reactors stay on paper or start feeding the grid.
Why Florida is suddenly serious about small modular reactors
Florida’s current energy mix is both cheap and fragile, a combination that explains why small modular reactors are getting a fresh look. The state has not instituted climate mitigation policies and relies on natural gas for 75 percent of its electricity, more than any other large state, which leaves households and businesses exposed when fuel prices spike or pipelines are disrupted. At the same time, stronger storms and higher temperatures are pushing demand up just as transmission lines and gas infrastructure are most at risk.
Small modular reactors, or SMRs, are being pitched as a way to break that dependence by adding steady, carbon free power that does not depend on the sun shining or the wind blowing. Advocates argue that SMRs produce steady, carbon free electricity that can keep the grid running when transmission lines fail and that they can be sited closer to load centers than traditional reactors, which is particularly attractive in a peninsula where long-distance lines are vulnerable to hurricanes, a case laid out in detail by Dec commentary. In that framing, SMRs are less about chasing climate targets and more about hardening a system that already runs hot and has little margin for error.
The legislative blueprint taking shape in Tallahassee
For SMRs to move from concept to construction, Florida needs a legal framework that treats them as a distinct class of infrastructure rather than a curiosity. Lawmakers have started to build that framework with House Bill 1461, a measure on Advanced Nuclear Reactors that would, among other things, authorize the Public Service Commission to regulate advanced nuclear reactors in this state. The same bill would authorize the Department of Health, referred to as DOH, and the Department of Environmental Protection, or DEP, to exercise specific oversight, folding these technologies into existing health and environmental review systems instead of improvising new ones on the fly.
Supporters of this approach argue that Florida, as a sovereign state, should have the right to license and regulate advanced nuclear through the Public Service Commission rather than waiting passively on federal decisions. A detailed blueprint circulated in Jan lays out how that authority could be used to streamline approvals while still requiring robust safety and financial reviews, and it frames Florida as leading the nation in asserting state level control over advanced nuclear deployment. Additionally, the bill amends existing statutes to incorporate advanced nuclear energy into Florida’s energy policy, revising planning rules and setting an effective date of July 1, 2026, as summarized in Additionally, which would lock SMRs into the same long term resource planning process that now favors gas.
The regulators and utilities preparing the ground
Even the most carefully drafted statute will not keep the lights on if regulators and utilities are not ready to act on it. In 2024, the Governor enacted a law requiring the Commission to study and evaluate the technical and economic feasibility of using advanced nuclear technologies in Florida, and the Commission has since worked with the Office of Energy in compiling that report, according to a Mar news release. That study process is not just academic; it will shape how the Public Service Commission weighs SMR proposals against new gas plants or large solar farms in future rate cases.
On the utility side, companies are starting to position specific sites for potential reactors even before they commit to building them. While Duke Energy has yet to make a decision to build new nuclear units, it has submitted an ESP, or early site permit, for a coal plant location, a move that preserves the option to replace fossil capacity with nuclear at that site in the future, as detailed in a While Duke Energy report. That kind of pre-permitting is crucial for SMRs, which can be added in phases; once a site is cleared, a utility can add modules over time as demand grows or as older gas units retire, rather than betting everything on a single massive project.
A nuclear state looking to upgrade its fleet
Florida is not starting from scratch on nuclear power, which changes the politics and the practicalities of adding SMRs. Florida is already a leader in nuclear innovation, hosting four nuclear units and the nation’s only digital nuclear training reactor, and those assets give the state a workforce and regulatory culture that is familiar with atomic energy, as highlighted in a Jul analysis. That same commentary argues that if Florida moves thoughtfully, responsibly and together, it can use SMRs to cut carbon emissions without sacrificing reliability or affordability.
The existing fleet is concentrated in two coastal complexes that illustrate both the strengths and vulnerabilities of traditional nuclear. Four nuclear generating units operate in the state, with two at Turkey Point in Miami, Dade County and two in a St. Lucie County plant, according to an Apr report that also notes the potential for new reactors at Florida’s many military installations. Those sites have delivered low carbon power for decades, but they are large, coastal and exposed, which is one reason SMR advocates talk about moving future units inland, closer to military bases and industrial hubs that can use both electricity and process heat.
The risks, rewards and political stakes ahead
Behind the technical details sits a blunt political and economic calculation: Florida’s energy policy relies heavily on natural gas, creating a dependency the state aims to reduce. New legislation would allow advanced nuclear projects to move forward more quickly, but even with streamlined rules, any SMR project will still face years of permitting and planning, as a Jan opinion piece on Florida’s energy risks makes clear. I see that tension as the core political challenge: voters want lower bills and fewer blackouts now, but the investments that could deliver that stability will not pay off until the 2030s.
Lawmakers weighing these choices are being told that the drivers behind advanced nuclear are not just environmental, but also about growth and resilience. Neeley identified three main drivers behind the renewed interest in advanced nuclear: new small modular reactor designs that can be factory built, the need to support a rapidly growing population and economy, and the desire for a more resilient and affordable energy supply, according to a Nov account of legislative hearings. Taken together with the emerging statutory framework, the Commission’s feasibility work and early moves like Duke Energy’s ESP, those arguments suggest that Florida’s future grid may well be anchored by small modular nukes, not as a silver bullet, but as the firm, always on complement to solar, storage and whatever gas remains.
