Key Highlights
- Constellation Energy and Walmart have finalized a 15-year agreement for nuclear power procurement
- The Dresden Clean Energy Center in Illinois will deliver approximately 176 megawatts of electricity
- Agreement incorporates 30 megawatts from future efficiency enhancements at the Dresden facility
- Energy delivery commences through two separate contracts in 2029 and 2030
- Represents Walmart’s inaugural nuclear energy purchase and among the earliest such partnerships between a leading U.S. retailer and nuclear power supplier
On Tuesday, Constellation Energy (CEG) and Walmart (WMT) revealed a landmark nuclear energy procurement partnership, representing a historic milestone as the first such arrangement between a prominent American retailer and a nuclear electricity provider.
At the time of publication, CEG stock showed gains of 0.54%, trading at $275.53.
Constellation Energy Corporation, CEG
The partnership terms specify that Constellation will deliver approximately 176 megawatts of power from its Dresden Clean Energy Center located in Morris, Illinois. This figure encompasses 30 megawatts of new generation capacity resulting from scheduled efficiency enhancements at the nuclear facility.
The electricity will power Walmart’s state-of-the-art perishable goods distribution center, presently being constructed in Belvidere, Illinois. This marks Walmart’s entry into nuclear energy procurement.
Structured as two separate 15-year agreements, the arrangement will begin delivering power in 2029 and 2030. Walmart’s purchase encompasses energy, environmental credits, and capacity rights under both contractual frameworks.
Additionally, this partnership supports financial justification for “uprates” at Dresden — operational enhancements that increase electricity generation from current nuclear infrastructure without requiring new facility construction. This approach represents an economically efficient method to expand carbon-free power generation.
About the Dresden Clean Energy Center
Dresden ranks among Constellation’s most substantial nuclear generation facilities. Operating licenses extend through 2049 and 2051, and the plant sustains over 1,100 regional employment positions. Constellation secured Dresden’s license extension in December 2025.
Constellation maintains 55 gigawatts of combined generating capacity spanning nuclear, natural gas, geothermal, hydroelectric, wind, and solar installations.
Jim McHugh, Constellation’s Senior Executive Vice President and Chief Commercial Officer, stated the partnership “reflects long-term stewardship of critical infrastructure, the communities it serves, and the energy system that powers American growth.”
Walmart maintains approximately 175 retail locations and membership clubs throughout Illinois, employing more than 55,000 associates statewide.
Rising Corporate Interest in Nuclear Energy
Nuclear energy appeals to major corporations due to its ability to deliver consistent carbon-free electricity — operating continuously regardless of time or weather, unlike intermittent renewable sources such as solar or wind.
This partnership aligns with an expanding trend of major enterprises securing extended nuclear supply agreements to satisfy both operational energy requirements and environmental sustainability objectives.
Constellation has demonstrated significant recent activity across multiple initiatives. Bernstein SocGen Group recently launched coverage with an outperform designation, highlighting the corporation’s 22 gigawatts of nuclear generation capacity and its Calpine acquisition as notable strengths.
Constellation also recently finalized a 25-megawatt geothermal expansion at The Geysers facility in California via its Calpine division, supplying electricity for more than 25,000 residences each year.
The corporation additionally announced a secondary stock offering of 11 million shares priced at $281 per share, though Constellation will not collect proceeds from this transaction.
With Dresden’s two reactors authorized to operate through 2049 and 2051, both organizations benefit from an extended timeline under this new partnership arrangement.
