Three Mile Island nuclear plant to restart for Microsoft data centers

Microsoft has partnered with Constellation Energy to revive the Three Mile Island nuclear plant in Pennsylvania, which was shut down after a major accident in 1979. Constellation Energy plans to invest $1.6 billion to restart Unit 1 of the plant, with Microsoft agreeing to purchase all of the plant's energy output for 20 years starting in 2028. The deal is part of Microsoft's efforts to secure new energy sources for its data centers, which power cloud computing and AI models. The agreement comes as policymakers seek to address the country's fraying electric power supply.
