In a move reflecting the surging demand for clean energy to fuel the AI revolution, U.S. energy regulators have granted a regulatory waiver to accelerate the restart of the Three Mile Island nuclear plant. According to reports, this decision aims to expedite the grid connection process in Pennsylvania, ensuring faster power delivery. The restart is specifically designed to meet Microsoft’s requirements for carbon-free electricity to power its expanding data center footprint in the region.
This development comes as Big Tech firms race to secure stable energy sources, with Microsoft having signed a 20-year power purchase agreement with plant operator Constellation Energy. In comparison to peers, Amazon recently acquired a nuclear-powered data center from Talen Energy for $650 million (per Reuters reports), while Google has invested in small modular reactors (SMRs) with Kairos Power (per market data). These moves underscore a strategic sector-wide shift toward nuclear energy as a cornerstone for sustainable data center operations.
