Imagine a quiet Iowa town, its skyline once dominated by the steady hum of a nuclear plant, now silent since 2020. But what if that silence could be broken—not by nostalgia, but by the relentless energy demands of artificial intelligence? The Duane Arnold nuclear plant, nestled northwest of Cedar Rapids, is poised for a comeback, driven by the tech industry’s insatiable appetite for power. This isn’t just a story about a shuttered facility; it’s about how the future of energy and technology are colliding in unexpected ways.
The Nuclear Renaissance Fueled by AI
The world of energy is shifting, and it’s happening faster than most of us realize. With artificial intelligence reshaping industries, the demand for electricity to power sprawling data centers has skyrocketed. These facilities, which train and run AI models, consume energy at a rate that makes your home’s electric bill look like pocket change. Enter nuclear power—a reliable, carbon-free energy source that’s suddenly finding new life in the face of this tech-driven surge.
In Iowa, the Duane Arnold nuclear plant is at the heart of this transformation. Owned by NextEra Energy, the facility shut down in 2020 due to economic pressures, outcompeted by cheaper natural gas and renewables. But the tides are turning. With tech giants racing to build AI infrastructure, nuclear plants like Duane Arnold are being eyed as the key to meeting this unprecedented demand. Why? Because nuclear offers something renewables can’t always guarantee: consistent, high-capacity power.
Why Duane Arnold Matters
Let’s get one thing straight: restarting a nuclear plant isn’t like flipping a switch. It’s a massive undertaking, both logistically and financially. Yet, Duane Arnold is one of only a handful of mothballed reactors in the U.S. deemed viable for a restart. If successful, it could bring 600 megawatts of electricity back to the grid—enough to power over 400,000 homes or, more likely, a cluster of power-hungry data centers.
NextEra Energy, a heavyweight in both nuclear and renewable energy, is betting big on this project. They’ve already secured approval from the Federal Energy Regulatory Commission to reconnect Duane Arnold to the grid, a critical step toward restarting operations by late 2028. But it’s not just about flipping the plant back on. It’s about positioning Iowa as a hub for the tech industry’s energy needs.
Restarting Duane Arnold is a unique opportunity to meet the growing energy demands of the future.

I’ve always found it fascinating how old technologies can find new purpose. Nuclear power, once written off as too costly or risky, is now being hailed as a clean energy savior. The irony? It’s not environmentalists driving this revival—it’s tech companies.
The AI Energy Crunch
Why is nuclear suddenly so attractive? To answer that, we need to talk about AI. Training large language models or running cloud-based AI applications requires an obscene amount of electricity. A single data center can consume as much power as a small city. And with tech giants like Microsoft and Google expanding their AI operations, the strain on the grid is only getting worse.
Renewables like solar and wind are great, but they’re weather-dependent. Nuclear, on the other hand, runs 24/7, delivering a steady stream of power that data centers crave. This is why we’re seeing a wave of nuclear restarts across the U.S., from Palisades in Michigan to Three Mile Island in Pennsylvania. Duane Arnold is next in line, and it’s no coincidence that tech companies are circling.
- High energy demand: AI data centers require constant, reliable power.
- Carbon goals: Tech companies aim to reduce emissions with clean energy.
- Economic upside: Nuclear restarts are cheaper than building new plants.
Perhaps the most interesting aspect is how this shift is reshaping local economies. A restarted Duane Arnold could turn the area around Cedar Rapids into a data center hotspot, bringing jobs and investment. But it’s not without challenges.
The Challenges of a Nuclear Comeback
Reviving a nuclear plant is no walk in the park. Duane Arnold’s restart is a capital-intensive endeavor, with NextEra planning to spend up to $100 million in 2025 alone. Transformers, cooling towers, and other infrastructure need replacing, and supply chain delays could push the timeline beyond 2028. Then there’s the regulatory hurdle: the Nuclear Regulatory Commission must give its blessing, and that’s never a sure thing.
Still, the financial case is compelling. Unlike new nuclear builds, which can cost billions and take decades, restarting an existing plant is a relative bargain. Plus, there’s the potential for lucrative power purchase agreements with tech companies desperate for reliable energy. Microsoft, for instance, has already inked a deal to support the Three Mile Island restart. Could a similar deal be in the works for Duane Arnold?
| Plant | Location | Restart Timeline | Power Output |
| Duane Arnold | Iowa | 2028 | 600 MW |
| Palisades | Michigan | 2025 | 800 MW |
| Three Mile Island | Pennsylvania | 2027 | 837 MW |
The numbers speak for themselves, but the real question is whether the industry can deliver on time. Nuclear projects have a notorious history of delays, and any hiccups could dampen the enthusiasm for this revival.
A New Era for Nuclear Power
The resurgence of nuclear power feels like a plot twist in the energy story. For years, the industry struggled against cheap natural gas and the rise of renewables. Now, it’s being pulled back into the spotlight by an unlikely ally: artificial intelligence. But this isn’t just about meeting demand—it’s about redefining what nuclear power means in a tech-driven world.
NextEra’s CEO has called projects like Duane Arnold “unicorn opportunities,” and I can’t help but agree. These restarts are rare chances to leverage existing infrastructure for modern needs. But they also come with risks—financial, logistical, and political. With renewable energy facing headwinds from policy changes, like the phase-out of key tax credits by 2027, nuclear could fill the gap.
Nuclear power is no longer just a relic of the past; it’s a cornerstone of our energy future.

Personally, I find the marriage of nuclear power and AI both exciting and a little surreal. It’s like watching two worlds collide—one rooted in decades-old technology, the other pushing the boundaries of innovation. Yet, it makes perfect sense. As AI continues to grow, so will its energy needs, and nuclear might just be the answer we’ve been overlooking.
What’s Next for Iowa and Beyond?
So, what does this mean for Iowa? A restarted Duane Arnold could transform the region, attracting tech companies and boosting the local economy. But it’s bigger than that. This project is part of a broader trend—one where nuclear power is reclaiming its place in the energy mix. If successful, Duane Arnold could pave the way for other mothballed plants to come back online.
But let’s not get ahead of ourselves. The road to 2028 is long, and there are plenty of hurdles to clear. Supply chain issues, regulatory approvals, and public perception of nuclear power could all complicate things. Still, the potential rewards are massive, both for NextEra and for the tech industry.
- Secure funding: NextEra needs to lock in power purchase agreements.
- Overcome logistics: Replacing critical infrastructure like transformers.
- Navigate regulations: Gaining approval from federal agencies.
In my view, the Duane Arnold restart is a test case. If it succeeds, it could spark a wave of similar projects across the country. If it falters, it might cool the enthusiasm for nuclear’s comeback. Either way, it’s a story worth watching.
The Bigger Picture
The revival of nuclear power isn’t just about one plant in Iowa. It’s about how we power the future. AI is pushing the boundaries of what’s possible, but it’s also exposing the limits of our current energy systems. Nuclear offers a way to bridge that gap, providing clean, reliable power at a scale renewables can’t yet match.
At the same time, this trend raises questions. Can the nuclear industry overcome its historical challenges? Will tech companies continue to invest in clean energy as costs rise? And what does this mean for the renewable energy sector, which has been the darling of the energy world for so long?
These are big questions, and I don’t pretend to have all the answers. But one thing’s clear: the energy landscape is changing, and projects like Duane Arnold are at the forefront. Whether it’s a roaring success or a cautionary tale, this is a moment that could define the next decade of power generation.
Final Thoughts
The story of Duane Arnold is more than just a technical or financial one—it’s a glimpse into the future. As AI continues to reshape our world, the energy that powers it will need to keep pace. Nuclear power, once relegated to the sidelines, might just be the unsung hero we need. But it’s not without risks, and the journey to 2028 will be anything but smooth.
For now, all eyes are on Iowa. Will Duane Arnold rise from its slumber to fuel the AI revolution? Only time will tell, but one thing’s for sure: this is a space worth watching. What do you think—can nuclear power make a comeback, or is it too little, too late?
