A new life is proposed for Three Mile Island supplying power to Microsoft data centers

The owner of the shuttered Three Mile Island nuclear power plant said Friday that it plans to restart the reactor under a 20-year agreement that calls for tech giant Microsoft to buy the power to supply its data centers with carbon-free energy. The announcement by Constellation Energy comes five years after its then-parent company, Exelon, shut down the plant, saying it was losing money. The plant, on an island in the Susquehanna River just outside Harrisburg, was the site of the nation’s worst commercial nuclear power accident, in 1979.
