Constellation Energy Corporation (NASDAQ: CEG) and Walmart (NYSE: WMT) have announced a long-term nuclear power purchase agreement covering emissions-free electricity from Constellation’s Dresden Clean Energy Center in Illinois.
The deal, announced on June 23, covers approximately 176 megawatts of wholesale electricity supply, which includes 30 MW of newly expanded generating capacity at the Dresden facility.
Walmart will purchase energy, environmental attributes, and capacity under two separate 15-year terms, with the first beginning in 2029 and the second commencing in 2030.
The agreement is designed to support reliable nuclear energy supply across the region while helping Walmart access cleaner electricity and strengthen local energy infrastructure.
Jim McHugh, Senior Executive Vice President and Chief Commercial Officer at Constellation Energy, said the deal reflects “long-term stewardship of critical infrastructure, the communities it serves, and the energy system that powers American growth.”
Capacity uprates at the Dresden Clean Energy Center will generate enough new power to support Walmart’s previously announced high-tech perishable distribution center, currently under development in Belvidere, Illinois.
The Belvidere facility represents a significant infrastructure investment by Walmart, and securing a dedicated clean energy source underscores the retailer’s broader commitment to sustainable operations.
Constellation Energy is a major player in the generation, marketing, and supply of clean electricity and renewable energy products, with operations spanning several key U.S. power regions.
The company’s geographical segments include Mid-Atlantic, Midwest, New York, the Electric Reliability Council of Texas, and Other Power Regions, giving it broad reach across American energy markets.
Founded in 1960 and headquartered in Baltimore, Maryland, Constellation Energy has positioned itself as a central supplier in the growing market for emissions-free nuclear power.
The agreement signals continued momentum in corporate procurement of nuclear energy, as large companies increasingly seek stable, long-term sources of clean electricity to meet sustainability and operational goals.
Nuclear power’s reliability and zero-emissions profile have made it an attractive option for major corporations looking to lock in energy supply well into the next decade and beyond.
