Key Takeaways

- Google partnering with NextEra Energy to reopen Iowa’s Duane Arnold Energy Center (closed 2020 after windstorm damage); 600+ MW nuclear plant targeted for early 2029 restart pending regulatory approval.
- Follows Microsoft-Constellation deal to restart Three Mile Island, Meta-Constellation deal for Illinois plant; nuclear provides 24/7 low-carbon power for AI data centers. Deloitte: new nuclear could meet 14% of data center power demand growth over next decade.
- Trump wants to quadruple nuclear generation over 25 years; signed executive orders to speed licensing. Public support at 60% (up from 43% in 2020 per Pew). Google also investing in geothermal, carbon capture, wind/solar, and nuclear fusion long-term.
- Sierra Club raises safety concerns over “decades old” plant with “known safety flaws” and nuclear waste; components may have degraded during five-year decommissioning. Central Iowa Power Cooperative will buy excess output.
What Happened?
Google announced Monday it is partnering with NextEra Energy to reopen Iowa’s Duane Arnold Energy Center, a nuclear plant that closed in 2020 after windstorm damage. The plant would provide over 600 MW of nuclear energy for the regional grid, targeting early 2029 restart pending regulatory approval. Central Iowa Power Cooperative will buy output not used by Google. The move follows Microsoft-Constellation’s deal to restart Pennsylvania’s Three Mile Island and Meta-Constellation’s deal for Illinois’ Clinton Clean Energy Center.
For Google, nuclear provides 24/7 low-carbon power for AI data centers; the company is also investing in geothermal, carbon capture (announced first project last week at Illinois gas plant storing 90% of emissions), wind/solar, and nuclear fusion long-term. Google’s Michael Terrell said the company is interested in upgrading existing plants “to squeeze more megawatts out of them” since building new reactors is time-consuming and expensive. Trump wants to quadruple nuclear generation over 25 years and signed executive orders to speed licensing.
Public support is at 60% (up from 43% in 2020 per Pew). Deloitte says new nuclear could meet 14% of data center power demand growth over the next decade. Sierra Club raised safety concerns over the “decades old” plant with “known safety flaws,” nuclear waste, and potential component degradation during five-year decommissioning. Brookfield Asset Management is in talks to buy two inactive South Carolina reactors.
Why It Matters
The deal underscores Big Tech’s nuclear pivot to meet exploding AI data center power demand (24/7, low-carbon, grid-scale). For Google, nuclear diversifies its energy mix beyond intermittent wind/solar, addressing AI’s insatiable power needs while maintaining carbon commitments. For NextEra, restarting dormant plants is faster/cheaper than building new reactors (which take years and thousands of workers), unlocking stranded assets and creating a new revenue stream. The trend (Microsoft, Meta, Google, Brookfield) validates nuclear’s comeback after decades of stagnation, driven by bipartisan support, Trump’s quadrupling goal, and rising public acceptance (60% support).
For investors, nuclear restarts are a lower-risk path than new builds, with existing infrastructure and regulatory precedent. Deloitte’s 14% data center demand projection signals material upside for nuclear operators (Constellation, NextEra) and uranium miners. However, safety concerns (Sierra Club’s “known flaws,” waste, degradation) and regulatory hurdles remain risks—any restart delays or incidents could derail momentum. The Iowa deal also highlights regional grid benefits: Central Iowa Power Cooperative buying excess output spreads economic gains beyond Big Tech.
What’s Next
Watch regulatory approval timeline for Duane Arnold’s 2029 restart—any delays or safety objections could slow momentum. Monitor Microsoft’s Three Mile Island restart (precedent for Google’s deal) and Brookfield’s South Carolina talks. Track Google’s other nuclear bets: small modular reactors (Kairos Power deal) and fusion investments. For NextEra and Constellation, watch stock performance as nuclear restarts scale. Monitor Trump administration licensing reforms and whether they accelerate approvals.
Track public sentiment—any nuclear incidents could reverse 60% support. For data center power demand, watch Deloitte’s 14% nuclear projection and whether supply keeps pace. Risks: regulatory rejection, safety incidents, cost overruns, or component degradation making restarts uneconomical. Catalysts: successful restarts, Trump policy support, or AI power demand exceeding forecasts. Favor nuclear operators (NextEra, Constellation) and uranium miners; monitor Big Tech capex for energy infrastructure.
