Walmart signed a long-term power purchase agreement with Constellation Energy for emissions-free electricity from the Dresden Clean Energy Center in Illinois, marking one of the first agreements of its kind between a major U.S. retailer and a nuclear energy facility. The deal covers approximately 176 MW of wholesale supply, including 30 MW of expanded generating capacity, through two 15-year terms beginning in 2029 and 2030.
The agreement supports planned efficiency upgrades at the nuclear facility while helping provide enough new power to the grid to support Walmart's high-tech perishable distribution center under development in Belvidere, Illinois. It also strengthens local energy infrastructure and supports regional jobs.
For Walmart, the agreement expands access to reliable, emissions-free electricity, reflecting the growing role of existing nuclear generation in helping large companies meet long-term energy needs.
