Microsoft Plans to Restart Three Mile Island Nuclear Plant

Microsoft has reached a significant agreement with Constellation Energy to restart the decommissioned Unit 1 of the Three Mile Island nuclear power plant, aiming to power its growing data centers, particularly for AI technologies. The project, which requires regulatory approval, is expected to cost around $1.6 billion and is projected to be operational by 2028, generating 837 megawatts of electricity—enough to supply approximately 700,000 homes. This move comes as data center energy demands are set to double by 2030, prompting tech companies to explore nuclear energy as a stable, low-carbon power source. Microsoft aims to achieve carbon negativity and has committed to sourcing 100% clean energy for its operations by 2025. Although the agreement is seen as a milestone towards decarbonizing energy grids, it faces potential regulatory hurdles and local opposition. The initiative reflects a broader trend among tech firms seeking reliable energy solutions in the face of soaring power requirements for AI applications.
