Microsoft just signed a deal to revive the shuttered Three Mile Island nuclear power plant. If approved by regulators, the software maker would have exclusive rights to 100 percent of the output in order power its AI data centers.

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.

The Three Mile Island Nuclear plant, home of the worst nuclear accident in U.S. history, would restart under a deal in which Microsoft purchases all its power.
