According to Odaily, Microsoft has entered into a 20-year agreement with Constellation Energy Corporation to restore the Three Mile Island Unit 1 reactor. This initiative aims to establish the Crane Clean Energy Center, part of Microsoft's efforts to power its artificial intelligence operations with carbon-free energy. Constellation Energy will provide Microsoft with 835 megawatts of power and invest approximately $1.6 billion to bring the facility online, with a target completion date in 2028. The agreement is pending approval from the Nuclear Regulatory Commission (NRC), state officials, and local authorities.

The Three Mile Island nuclear plant, located near the Susquehanna River in Pennsylvania, experienced a core meltdown on March 28, 1979. This incident was rated as a Level 5 event on the International Nuclear Event Scale, which ranges from 1 to 7. The Three Mile Island accident remains the most severe nuclear incident in the United States to date. However, it is considered more controllable compared to subsequent nuclear disasters at Chernobyl and Fukushima.
