Meta Platforms Inc (NASDAQ:META, ETR:FB2A, SWX:FB) has signed a 20-year agreement to purchase emissions-free nuclear energy from Constellation Energy’s Clinton Clean Energy Center in Illinois, the companies said on Tuesday.
Beginning in June 2027, Meta will purchase the entire output—roughly 1.1 gigawatts—of electricity from the Clinton facility's single nuclear reactor, marking the social media giant’s largest power deal to date.
The news sent shares of Constellation up 6.2% in early trading.
Constellation said the long-term power purchase agreement (PPA) will allow it to relicense the plant and continue operating for an additional 20 years, after subsidies that kept it viable were set to expire.
“This agreement with Meta ensures the long-term future of the Clinton Clean Energy Center,” Constellation said in a post on the social media platform X, noting the deal supports 1,100 high-paying local jobs, delivers $13.5 million in annual tax revenue, and includes $1 million in charitable giving over five years.
The company added that the deal would also expand the plant’s clean energy output by 30 megawatts.
The agreement highlights growing corporate interest in nuclear power as a reliable source of carbon-free energy. For Constellation, the deal removes uncertainty around Clinton’s future and could lay the groundwork for expansion at the site, potentially including a new reactor.
The agreement also supports Meta’s clean energy targets and its operations in the region.
