Microsoft to Reopen America's Infamous Three Mile Island Nuclear Plant for AI Energy Needs
The Three Mile Island energy plant, site of the most significant nuclear accident in U.S. history, is set to reopen as Microsoft addresses its growing demand for power. The tech giant has signed a 20 year agreement to purchase energy from the Pennsylvania based plant, which is scheduled to restart in 2028 after undergoing upgrades.
A Clean Energy Initiative for AI Expansion
Microsoft’s agreement aims to secure a sustainable energy source to support its expanding AI data centers, which require large amounts of power. The plan, which must now go through regulatory approval, marks a significant step in the company’s efforts to source clean energy.
Constellation Energy's Role in the Reopening
Constellation Energy, the current owner of the plant, confirmed that the reactor set to restart is located next to, but remains independent of, the unit involved in the 1979 accident. The original incident caused no injuries or deaths but generated widespread public fear, hindering nuclear power development in the U.S. for decades.
With rising concerns over climate change and increasing energy demands from AI, nuclear energy is gaining renewed attention. Constellation’s CEO, Joe Dominguez, stated that the agreement symbolized the "rebirth of nuclear power as a clean and reliable energy resource."
A Symbol of Nuclear Energy’s Revival
Dominguez highlighted that prior to its closure due to economic factors, the plant was one of the safest and most reliable nuclear facilities. He expressed enthusiasm about reopening it under a new name and mission, emphasizing that nuclear plants are among the few energy sources capable of consistently delivering abundant carbon-free electricity.
Long Term Vision and Economic Benefits
Microsoft views the partnership as a milestone in its strategy to contribute to grid decarbonization. Constellation plans to invest $1.6 billion to modernize the plant, seeking approval to keep it operational until at least 2054. The plant’s reopening is expected to create 3,400 jobs and contribute over 800 megawatts of carbon free energy to the grid. According to a study by The Brattle Group, the project could also generate billions in taxes and economic benefits.
Historical Context: The 1979 Three Mile Island Incident
On March 28, 1979, the Three Mile Island plant experienced a partial meltdown due to a combination of mechanical failure and human error. The accident occurred in Unit 2, but Unit 1, which Microsoft plans to utilize, continued to operate until 2019. The plant’s closure was attributed to the economic pressures from cheaper natural gas at the time.
Growing Tech Interest in Nuclear Power
Microsoft isn't the only tech company exploring nuclear energy to meet rising power demands. Amazon has also entered into a deal involving nuclear energy to power its data centers, though the agreement is currently under regulatory review.
The Path Forward
Constellation is seeking to revive Three Mile Island as part of a broader effort to promote nuclear power’s role in providing reliable, clean energy for the future. With Microsoft’s backing, this move may set a precedent for how tech companies address their growing energy needs sustainably.
