What is the scope and duration of Walmart's nuclear power purchase agreement with Constellation Energy?

Walmart has signed two 15-year contracts with Constellation Energy to purchase approximately 176 megawatts of nuclear-generated electricity—including 30 megawatts from planned efficiency upgrades—at Constellation’s Dresden Clean Energy Center in Illinois, with deliveries beginning in 2029 and 2030 to power Walmart’s new high-tech perishable distribution center in Belvidere, Illinois.

Why is this deal considered significant in the context of U.S. corporate energy procurement?

This agreement is among the first long-term nuclear power purchase deals between a major U.S. retailer and a nuclear energy provider, highlighting growing corporate demand for reliable, around-the-clock clean baseload power—and marking a strategic shift toward nuclear energy as a key component of large-scale decarbonization efforts by major commercial entities.
