Meta signed a 20-year deal with Constellation Energy to buy 1.1 gigawatts of nuclear power from Illinois’ Clinton Clean Energy Center starting in 2027, according to CNBC. The agreement secures the plant’s future after its zero-emission credit expired, supports its relicensing, and will boost output by 30 megawatts. The plant will power the regional grid rather than Meta’s data centers directly, helping the company meet its clean energy goals. The deal with Constellation is Meta’s first official step into nuclear energy. Meta said the Clinton plant deal supports its AI goals and strengthens U.S. energy leadership by ensuring clean, reliable power. Constellation shares jumped over 15% on the news.
