Connecticut’s renewed interest in nuclear energy is picking up steam as the state faces rising electricity demand and ambitious climate goals. With Connecticut Yankee long gone and Millstone the only plant still running, officials are now looking at advanced small modular reactors and even, maybe someday, fusion.
They’re holding public workshops, reaching out to towns all over Connecticut. The aim? To hear what folks think and figure out how nuclear might fit into the state’s energy future.

Recent federal and state policy shifts, money worries, and safety debates all shape the conversation. There’s a lot of talk about carbon-free “always-on” power, especially for big energy users like data centers that need reliable juice.
Connecticut’s Nuclear Conversation Reignites as Power Demand Grows
DEEP Commissioner Katie Dykes and other state officials warn that by the mid-2030s, Connecticut could face real electricity shortages if planning drags. They’re stressing the need to keep power affordable and reliable, especially during those New England cold snaps when natural gas prices spike.
Recent policy moves at both the federal and state levels have kicked off local discussions about whether advanced small modular reactors (SMRs)—which are smaller, factory-built, and pitched as safer—could play a big role here.
Municipalities from all corners are getting invites to public workshops and info sessions. At a May 13 meeting, for example, officials covered both traditional fission and a quick overview of fusion, hoping to educate communities about the tech, safety, and environmental factors.
They’re also asking for local input about where, if anywhere, these new facilities might belong.
Momentum from Policy and Public Workshops
There’s clear momentum for nuclear options, thanks to broader policy shifts. An executive order from President Trump in May 2025 and a 2025 Connecticut climate bill with sharp emissions cuts have stirred up fresh interest in nuclear.
DEEP officials say these workshops are key for explaining new technologies, safety features, and environmental impacts as Connecticut weighs nuclear—including maybe fusion down the line—as a way to meet demand and climate goals.
Supporters say SMRs could deliver reliable, carbon-free “always-on” power. That could help steady prices, especially when demand spikes. Critics aren’t so sure. They argue nuclear isn’t truly renewable, depends on limited uranium, and creates radioactive waste with no federal permanent storage.
The conversation stretches from workforce development and plant safety to decommissioning costs and the headaches of cost overruns in a deregulated market.
What SMRs Could Mean for CT
Backers of SMRs claim a fleet of these reactors—each under 300 megawatts, with clusters possibly reaching 1,200 megawatts—could provide steady, low-emission power for Connecticut. With growing electricity needs and more data centers popping up, that could mean more stable prices and stronger infrastructure.
Advocates say the technology is safer and more flexible than old-school big reactors. Critics push back, raising questions about waste management and the true cost over the reactor’s life.
Connecticut’s leaders admit SMRs aren’t a magic fix. Any plan has to juggle energy reliability, emissions targets, safety, and what makes sense economically.
Some communities still worry about health and safety, even though decades of nuclear operation have shown strong safeguards and, in many places, accident-free records.
The conversation keeps circling around immediate power needs, long-term environmental responsibility, and the state’s budget realities.
Public Safety, Costs, and Debates
The debate covers risk perceptions, cancer worries near existing plants, and the fear of catastrophic accidents. Some studies suggest higher cancer risks nearby, but supporters point to tough federal and state safety rules, constant monitoring, and a long record of safe operation.
Costs are a wild card. Generation can be cheap, but building reactors isn’t. And no one’s quite sure who’ll pay if costs spiral in Connecticut’s deregulated market.
Connecticut’s climate ambitions only complicate things further. State leaders keep pushing for public engagement to explain new technology, safety steps, and environmental impacts. The big question lingers: can nuclear—now, or maybe fusion later—really meet future demand and tough emissions targets in a state packed with cities and industry?
Where Siting Might Begin in Connecticut
Connecticut’s municipalities are getting asked for input, including the biggest cities and some smaller towns. No official sites have been announced yet.
Officials say any future reactor or SMR project would need careful siting. They’ll have to think about safety, infrastructure, and what locals actually want.
People expect conversations to pop up in all sorts of places, from the coast to the inland towns. Some spots will definitely get more attention than others.
As the state figures out its next moves, residents in cities and towns—New London, Norwich, East Hartford, Waterford, Bridgeport—are watching closely. Policy, safety, and economics are all tangled up in this debate.
The Millstone plant in Waterford is still at the center of things. If Connecticut expands its nuclear footprint in the next decade, Millstone is where the conversation starts.
