Walmart Signs Nuclear Power Agreement for Illinois Distribution Center

Walmart announced on June 23 its first nuclear power purchase agreement, securing around 176 megawatts of wholesale electricity from Constellation's Dresden Clean Energy Center in Illinois, Newsweek reported. The contract covers two 15-year periods that begin in 2029 and 2030.

It will supply power to a high-tech perishable distribution center under development in Belvidere, Illinois, and will support planned efficiency upgrades at existing nuclear units.

Shayne Wahlmeier, senior vice president of energy at Walmart US, said the agreement builds on the company's history of energy investments. "Working with Constellation allows us to support new operations in Illinois while advancing our strategy in a way that prioritizes affordable, reliable, and clean energy for our business and the communities we serve," Wahlmeier stated.

Walmart operates around 175 stores and clubs in Illinois.

Constellation produces enough energy in the state to power more than 8 million homes, according to the retailer. The company has set a target of zero emissions across its global operations by 2040. Similar corporate nuclear deals have increased since 2024.

Microsoft signed a 20-year agreement in September 2024 with Constellation to restart Three Mile Island Unit 1 in Pennsylvania, delivering about 835 megawatts. Amazon signed an agreement in June 2025 with Talen Energy for up to 1.92 gigawatts from the Susquehanna plant through 2042.

Meta announced agreements in January 2026 with Vistra, TerraPower, and Oklo that could deliver up to 6.6 gigawatts by 2035.
