A deal between Constellation Energy and Microsoft will restart Pennsylvania’s Three Mile Island, the site of the country’s worst nuclear accident, to help power the tech giant’s growing artificial intelligence ambitions.

The owner of the shuttered Three Mile Island nuclear plant in Pennsylvania will invest $1.6 billion to revive it, agreeing to sell all the output to Microsoft Corp. as the tech titan seeks carbon-free electricity for data centers to power the artificial intelligence boom.

In a groundbreaking move, Microsoft and BlackRock are joining forces with a $30 billion investment over the next decade to drive advancements in artificial intelligence (AI). This massive investment not only highlights the growing significance of AI in global industries but also underscores the challenges of powering these cutting-edge systems.
