Constellation has signed a conditional loan agreement of up to $5 billion with the Department of Energy to fund power uprates at eight plants. Six are in Illinois (Braidwood, Byron, Clinton, Dresden, LaSalle and Quad Cities), with one more in Maryland (Calvert Cliffs) and one in Pennsylvania (Limerick).

Energy Secretary Chris Wright said the work would add 1.1 GW of capacity across 15 reactors. Several of the plants already sell power to Google, Amazon, Meta or Walmart under long-term contracts.
