Three Mile Island Nuclear Plant Set for Reboot to Power Microsoft Data Centers

The Three Mile Island nuclear plant in Pennsylvania, long dormant since the shutdown of its remaining reactor in 2019, is gearing up for a significant revival. Here are the key points:

Revival Plans: Constellation Energy plans to restart the plant to supply power to Microsoft’s data centers. The 20-year power contract will see Microsoft paying around $100 per megawatt-hour, nearly double the typical cost of renewable energy in the area.

Project Scope: The restoration of Unit 1 is projected to take four years and cost at least $1.6 billion. This unprecedented task will involve thousands of workers and significant upgrades to the facility, including restoring cooling towers and replacing major equipment.

Historical Context: Three Mile Island is infamous for a partial meltdown in 1979, which had lasting impacts on the U.S. nuclear industry. Successfully restarting the plant could signal a revival of nuclear energy in the U.S., particularly as it offers a carbon-free electricity source.

Regulatory Challenges: The project faces hurdles, including the need for licensing modifications and local opposition based on safety and environmental concerns. Activists are prepared to challenge the restart, citing the plant’s history and potential risks.

Market Demand: The push for nuclear energy comes amid rising electricity demands, particularly from tech companies like Microsoft, which are expanding their operations significantly. Constellation has already begun ordering equipment and preparing for restoration work, with construction expected to start in early 2025.

Environmental Considerations: While nuclear energy is seen as a clean alternative, concerns about radioactive waste management persist. The site currently stores spent nuclear fuel from Unit 1, and the decommissioning of Unit 2 is ongoing.

Future Outlook: The initial public hearing by the Nuclear Regulatory Commission on the restart plan is scheduled for October 25, marking a critical step in the process.
