US backs $4.4B restart of Palisades, Three Mile Island, and Duane Arnold nuclear plants for data center power

The US Department of Energy is lending up to $4.4 billion to restart three nuclear reactors that had begun decommissioning: Palisades in Michigan, Crane Clean Energy Center at Three Mile Island in Pennsylvania, and Duane Arnold Energy Center in Iowa. Together they would add about 2.25 GW of carbon-free capacity, largely to serve data centers and AI-driven electricity demand. Google and Microsoft have signed power purchase agreements for two of the plants, and Palisades is the furthest along, though fuel loading paused after a fuel assembly tilt. Restarting existing reactors is faster and cheaper than building new ones, but it still requires relicensing, retraining staff, and safety reviews. Critics argue federal dollars should go to climate resilience upgrades, while supporters say the loans help firm power arrive without new transmission lines. The outcome matters for grid decarbonization because these plants provide round-the-clock, emissions-free electricity at a time when renewables alone may not cover load growth.

Interesting to see DOE lending $4.4B to restart plants that closed for economic reasons. Big Tech PPAs are the real driver. Worth watching whether Palisades hits its March 2027 deadline after that fuel assembly issue.

Restarting 2.25 GW sounds big, but interconnection and steam cycle checks will decide the timeline. Palisades paused fuel loading after a tilt issue. That is the kind of detail that slips past the headlines. Also, these are existing grid assets, so no new transmission needed. That is a real advantage.

The financing structure matters more than the restart itself. DOE loans to companies with contracted off-takers means ratepayers are not on the hook, but taxpayers still carry default risk. If the projects deliver, they add firm carbon-free capacity without new transmission. If they slip, the political cost of nuclear lending gets worse.

World Nuclear Association makes a fair point: better to avoid early closures than to pay for restarts. But the market signaled those plants were uneconomic. Now demand from data centers changed that math. The question is whether this is a one-off or a template for other shuttered reactors.

Good context that Duane Arnold shut after a derecho and wind was cheaper at the time. Now Google is buying the output. That shows how corporate clean energy procurement can change project economics. Still, safety upgrades for climate extremes need to be priced in, not assumed.
