Microsoft and Constellation Energy Are Resurrecting Three Mile Island 45 Years After It Went Nuclear

The infamous Three Mile Island nuclear plant, best known for the 1979 accident that sent shockwaves across the U.S., is gearing up for a revival.

 Constellation Energy is giving Unit 1—the reactor that’s been offline since 2019—a second shot at life, and Microsoft has already jumped in to secure the energy it’ll generate. This is a historic moment in the world of tech and energy, as it marks the resurgence of nuclear power to meet the ballooning electricity demands of the AI-driven world.

Back in 2019, Unit 1 at Three Mile Island shut down because nuclear power just couldn't keep up with the bargain prices of natural gas and renewables. But times have changed. Fast forward to today, and with AI gobbling up energy faster than a Tesla on a road trip, nuclear’s carbon-free energy is starting to look pretty attractive—kind of like the movie moment when the nerdy girl takes off her glasses and everyone notices her.

Microsoft, which is rapidly growing its AI-driven data centers, needs a massive amount of power to keep everything humming. To meet that demand, they’ve just inked a 20-year deal to buy 835 megawatts from Three Mile Island—the biggest power purchase Constellation has ever done. If that doesn’t show how serious Microsoft is about its energy appetite, nothing will.

And no, Unit 2, the culprit behind the 1979 partial meltdown, is staying offline for good—nobody’s crazy enough to bring that one back. But Unit 1 is getting a $1.6 billion upgrade, and if everything goes according to plan, it’ll be back online by 2028, pending approval from the Nuclear Regulatory Commission. And Wall Street’s not sleeping on this either—Constellation’s stock surged 15% after the news broke, a clear sign that investors are betting big on nuclear making a serious comeback in the energy game.

The timing couldn’t be more crucial. As tech giants like Microsoft, Amazon, and Oracle rapidly expand their data centers, the demand for energy is reaching new heights, making dependable power sources more vital than ever. Goldman Sachs predicts that by 2030, data centers alone could gobble up 8% of all U.S. electricity—more than double today’s 3%. To give you some perspective, that’s an additional 290 terawatt hours of electricity, roughly the same as the annual energy consumption of Turkey (yes, the country, not your Thanksgiving bird).

Microsoft isn’t the only “Mag 7” stock betting on nuclear, either. Earlier this year, Amazon struck a deal to power its Pennsylvania data center with energy from the Susquehanna nuclear plant, and Oracle is exploring small nuclear reactors for future projects. Even Sam Altman, the brains behind OpenAI, is getting in on the action. He’s backing Oklo, a startup focused on advanced, compact nuclear reactors that can power anything from a data center to an entire town. The message is clear: the tech world is turning to nuclear energy to sustain its massive growth while keeping its carbon footprint in check.

Joe Dominguez, CEO of Constellation Energy, calls the restart of Three Mile Island “the most powerful symbol of the rebirth of nuclear power,” and with energy demand surging, he’s got a point.

Now, nuclear power isn’t exactly a dinner party topic everyone agrees on (you can thank Chernobyl for that), but if you’re betting on the long-term potential of clean, reliable energy, Constellation’s a name to watch. Their $1.6 billion gamble on Three Mile Island and a 20-year deal to send 835 megawatts to Microsoft show they’re all-in. Oh, and by the way, the stock’s up 104% year to date—so clearly, investors are buying the nuclear comeback story.
