Energy Department closes $5 billion loan to upgrade nuclear plants in three states

The U.S. Department of Energy announced a conditional loan commitment of up to $5 billion for Constellation Energy to add nearly 1.1 gigawatts of nuclear power across facilities in Illinois, Maryland, and Pennsylvania. Driven by surging electricity demand from major tech companies like Amazon, Google, and Meta, the federal financing aims to upgrade existing nuclear reactors. The agreement forms part of a broader Trump administration initiative pushing federal energy financing.
