US is restarting Palisades, Three Mile Island, and Duane Arnold nuclear plants for data center power

The U.S. Department of Energy is lending up to $4.4 billion to restart three shuttered nuclear plants: Palisades in Michigan, Crane Clean Energy Center at Three Mile Island in Pennsylvania, and Duane Arnold in Iowa. Together they would add 2.25 GW of carbon-free capacity, roughly enough for 2 million homes. Google and Microsoft have signed power purchase agreements for two of the plants, so data center demand is underwriting much of the restart cost. Supporters say restarting a reactor is faster and cheaper than building a new large one, and Palisades would be the first commercial reactor to return after beginning decommissioning. Critics question why taxpayers should back projects whose output is already contracted to Big Tech, and they point to safety upgrades needed for older plants. For grid watchers, this is a real test of whether nuclear restarts can add firm low-carbon power on a tight timeline.

The part that matters most to me is the power purchase agreements. Microsoft and Google are paying a premium for carbon-free power, which means the economics are no longer 'nuclear is too expensive.' That changes the financing story, even if DOE loans carry some risk.

Exactly. The PPA structure is the real signal. If hyperscalers are willing to lock in 20-year contracts at a premium, the market is saying low-carbon firm power has value. The DOE loan just lowers the hurdle rate.

Duane Arnold closed in part because wind and gas were cheaper, and now Google is paying to bring it back. It shows how data center load is reshaping the market. The question is whether restarting old reactors beats building new clean firm capacity on the same timeline.

I want to see the interconnection and maintenance details. Palisades already had a fuel loading pause, and TMI needs a full license restoration. Restarting a reactor is not just flipping a switch. The 2027 deadline for Palisades is tight for any surprise.

The taxpayer money debate is valid. These are private companies selling power to hyperscalers, so federal loans should be structured to capture downside, not just hand over cheap capital. If the projects deliver, fine, but the public should not eat the loss while Big Tech gets the power.

If data centers are paying a premium, then why do ratepayers need to guarantee the loans? I get the climate argument for nuclear, but the financing should match the risk. Otherwise we are back to socializing the downside and privatizing the upside.
