Constellation Energy Corp., the largest supplier of nuclear power in the United States, has entered a long-term agreement to provide electricity to Walmart Inc. from its Dresden nuclear facility in Illinois. The deal, announced Tuesday, entails Constellation supplying 176 megawatts of power, including 30 megawatts of additional capacity generated through planned upgrades at the plant.

The electricity supplied under this agreement will support a Walmart perishable goods distribution center, marking the retail giant’s initial purchase of nuclear-generated energy. The collaboration underscores a growing interest among industries beyond traditional technology sectors in securing emissions-free power sources that offer consistent, around-the-clock supply.

Nuclear energy is increasingly viewed as a reliable option to meet demand for clean electricity, especially for operations requiring a steady power flow, such as data centers hosting artificial intelligence applications. Walmart’s move reflects a broader trend of companies seeking to reduce carbon footprints by incorporating more sustainable energy sources into their supply chains.

The investment secured through this arrangement will also contribute to enhancements at the Dresden site, which is expected to expand the plant’s generating capacity by 30 megawatts. This initiative is part of ongoing efforts to maintain and modernize nuclear facilities to ensure stable, low-carbon energy provision.

By committing to nuclear power, Walmart and Constellation aim to demonstrate the viability of nuclear energy in supporting large-scale commercial operations while advancing corporate sustainability goals.
