Meta has signed a 20-year power purchase agreement (PPA) with constellation to source 1,121 megawatts of emissions-free nuclear energy from the Clinton Clean Energy Center, marking a significant step toward decarbonizing its rapidly growing AI infrastructure. The long-term deal supports Meta’s goal of matching 100% of its electricity use with clean energy while aligning with President Donald Trump’s renewed focus on expanding America’s nuclear sector.

Beginning in June 2027, the agreement ensures continued operation of the Clinton nuclear facility beyond the expiration of Illinois’ Zero Emission Credit (ZEC) program. The deal will also increase the plant’s output by 30 megawatts through upgrades, preserve 1,100 local jobs, deliver $13.5 million annually in tax revenue, and contribute $1 million over five years to local nonprofits.

“We are excited to partner with Constellation and the Clinton community to ensure the long-term operations of the nuclear plant, add new capacity, and help preserve over 1,000 jobs,” said Urvi Parekh, Head of Global Energy at meta. “Securing clean, reliable energy is necessary to continue advancing our AI ambitions.”

Joe Dominguez, CEO of Constellation, emphasized the strategic importance of investing in existing nuclear assets. “Supporting the relicensing and expansion of existing plants is just as impactful as building new ones,” he said. “Sometimes the most important part of our journey forward is to stop taking steps backwards.”

Under the agreement, Clinton will continue delivering reliable, zero-emissions power to the Midcontinent Independent System Operator (MISO) grid, which covers central and southern Illinois. Constellation is also considering further development at the site, including potential deployment of advanced or small modular reactors (SMRs), pending regulatory approval.

The announcement follows President Trump’s late-May executive orders aimed at overhauling the Nuclear Regulatory Commission and fast-tracking the deployment of new reactors. The orders also seek to revive domestic uranium mining and enrichment, signaling a sweeping effort to bolster U.S. energy independence and nuclear leadership.

Investor response was swift. Constellation shares jumped over 10% on the day, pushing the stock to a 55% gain year-to-date. The deal also lifted the broader nuclear sector, with OKLO rising more than 5% and NuScale Power gaining 6%.
