Constellation Energy has announced plans to restart the Three Mile Island nuclear plant following a 20-year power purchase agreement with Microsoft. This strategic move underscores the increasing demand for nuclear power, particularly to support Microsoft’s expanding AI operations. The revival of the nuclear facility is expected to significantly bolster clean energy initiatives, with the electricity generated being sold directly to Microsoft to fuel its AI data centers. Constellation Energy's stock has seen a rise following the news, highlighting investor optimism surrounding the partnership. The reopening of Three Mile Island not only marks a significant turnaround for the facility but also reflects a broader trend towards sustainable energy solutions in the United States.
