America’s Three Mile Island energy plant, infamous for the worst nuclear accident in US history, is preparing to reopen after Microsoft signed a 20-year deal to purchase power from the facility. The plant is scheduled to restart in 2028 following upgrades and will supply clean energy to support Microsoft’s growing data centres, especially those focused on AI. The agreement is pending regulatory approval.

Constellation Energy, the plant owner, confirmed that the reactor set to restart is separate from the unit involved in the 1979 accident, which, while not fatal, created significant public fear surrounding nuclear power. This deal represents a revival of interest in atomic energy, driven by increasing concerns about climate change and rising energy needs. The CEO of Constellation described this move as a “rebirth” of nuclear power, highlighting its potential as a dependable source of carbon-free energy.

The plant’s reopening is projected to create 3,400 jobs and add over 800 megawatts of carbon-free electricity to the grid, driving significant economic activity. Although the revival has faced some protests, it underscores a growing trend among tech companies, with Amazon also exploring nuclear energy to meet its expanding energy demands.
