Three Mile Island: From Meltdown to Microsoft’s AI Power Play
Three Mile Island unit 1 is coming back online, thanks to Microsoft and AI demand.
Remember Three Mile Island? That nuclear plant south of Harrisburg, Pennsylvania that gave us all a scare back in 1979? Well, it’s making a comeback, and this time it’s got Microsoft muscle (and money) in its corner.
A Brief History Lesson
Three Mile Island was home to two nuclear reactors. In March 1979, Unit 2 suffered a partial meltdown, causing the worst commercial nuclear accident in U.S. history. While Unit 1 kept chugging along, it eventually closed in 2019 due to economic pressures. Producing electricity there was more expensive than other providers using cheaper natural gas.New Owner, New Expectations
