## Three Mile Island Nuclear Plant Reboots to Power Microsoft's AI Ambitions
The site of America's most notorious nuclear accident is being resurrected to feed the energy-hungry artificial intelligence industry. In a deal that underscores the sheer scale of AI's power demands, Microsoft Corp. has committed to purchasing 100% of the electricity from Three Mile Island's remaining operational reactor for the next two decades. The September 2024 agreement with Constellation Energy Corp. brings the infamous Pennsylvania facility back online under a sanitized new identity: the Crane Clean Energy Center.

The 835-megawatt reactor, which continued operating long after its sister unit suffered a partial meltdown in 1979, will now dedicate its entire output to Microsoft's data centers and AI infrastructure. The 20-year power purchase agreement represents one of the most significant corporate bets on nuclear energy in recent memory—and a calculated gamble on public acceptance of atomic power in an era of climate urgency and digital expansion. Constellation, the largest operator of nuclear plants in the United States, is positioning the rebranded facility as a cornerstone of clean energy for the tech sector.

The revival signals a broader shift in how hyperscale technology companies are approaching their energy strategies. As AI workloads strain conventional power grids and pressure corporate climate commitments, nuclear energy—once considered too politically toxic and financially risky—is emerging as a viable solution for tech giants seeking reliable, carbon-free electricity. The Three Mile Island deal could set a precedent for similar arrangements, potentially unlocking dormant nuclear assets across the country. Yet questions remain about regulatory approval, community response, and whether the industry can overcome the lingering stigma attached to sites like Three Mile Island, where the worst nuclear accident in U.S. history still casts a long shadow.
