Constellation Energy (NASDAQ: CEG) and Walmart have signed a long-term nuclear power purchase agreement tied to Constellation’s Dresden Clean Energy Center in Illinois, marking Walmart’s first nuclear PPA and extending the growing use of nuclear contracts beyond the technology sector.
The agreement announced Tuesday covers about 176 megawatts of wholesale supply from Dresden, including 30 megawatts of additional generating capacity expected from planned uprates at the existing nuclear plant. Walmart will buy electricity, environmental attributes and capacity through two 15-year terms beginning in 2029 and 2030, the companies said.
Financial terms were not disclosed.
The deal comes as large corporate energy buyers seek longer-duration contracts for reliable, carbon-free electricity at a time when rising demand from data centers, advanced manufacturing and automated logistics facilities is tightening parts of the US power market. Nuclear power has increasingly become a preferred option for companies that need around-the-clock electricity rather than intermittent renewable generation alone.
