The owner of the shuttered Three Mile Island US nuclear power plant said 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 centres with carbon-free energy.

The announcement by Constellation Energy on Friday comes five years after its then-parent company Exelon shut down the plant, saying it was losing money and that Pennsylvania legislators had refused to subsidise it.
