Meta has cut a 20-year deal to secure nuclear power to help meet surging demand for artificial intelligence and other computing needs at Facebook’s parent company.

Constellation Energy Corp. agreed to sell power from an operating Illinois nuclear plant to Meta Platforms Inc., a deal that could spur construction of a new reactor at the site as artificial intelligence sends power demand soaring.

Meta has signed a 20-year contract with power giant Constellation Energy to keep an Illinois nuclear power plant running to power the tech giant's data centers. Nuclear energy from the Clinton Clean Energy Center will be used to support Meta's operations in the region starting in 2027, Meta said in an announcement Tuesday.
