Constellation and social networking company Meta have signed an agreement that will support the continued operation of the Clinton nuclear power station in Illinois for another 20 years.

Baltimore, Maryland-based Constellation said the power purchase agreement (PPA) will support Meta’s clean energy goals and operations in the region with 1,121 MW of nuclear energy from Clinton’s single boiling water reactor unit.

The deal will allow Constellation to increase Clinton’s output by 30 MW through plant uprates.
