Constellation Energy said it will restart a unit at Three Mile Island in Pennsylvania, the site of a partial nuclear meltdown in 1979, as part of a 20-year deal to provide energy to Microsoft's data centers for the tech giant's push into artificial intelligence, the company said Friday.
The Baltimore-based company said it would restart unit 1, which was undamaged in the accident but closed five years ago for economic and operational reasons, making a $1.6 billion investment to the plant's turbine, generator, power transformer and cooling and control systems.
