Grocery shopping has become a lot more complicated for customers.
Shoppers want low prices, but they also want fresh produce, cold dairy, reliable pickup, faster delivery, and shelves that are stocked when they walk into a store after work.
That puts more pressure on what happens behind the scenes.
For Walmart, the country’s largest grocer, keeping customers coming back is no longer just about what happens at the register. It depends on whether the company can move food faster, keep perishable items cold, reduce waste, and avoid disruptions that can leave customers with fewer choices.
This is why Walmart has spent the past several years investing in automation, faster delivery, new distribution centers, and technology that can make its grocery network more reliable.
Now Walmart is making another behind-the-scenes move that shoppers may not immediately notice, but could help support one of the most important parts of its business.
The retailer is turning to nuclear energy.
Walmart nuclear deal supports fresh grocery supply
Walmart and Constellation revealed June 23 that they have reached a long-term nuclear power purchase agreement tied to Constellation’s Dresden Clean Energy Center in Illinois.
The deal includes about 176 megawatts of wholesale supply, including 30 megawatts of expanded generating capacity.
Walmart will purchase energy, environmental attributes, and capacity through two 15-year terms beginning in 2029 and 2030.

In simpler terms, Constellation’s Dresden Clean Energy Center is a nuclear power plant that produces electricity for the region.
Nuclear plants can provide steady power day and night, unlike energy sources that depend more directly on weather or the time of day.
That matters for Walmart because the deal is expected to support its planned high-tech perishable distribution center in Belvidere, Ill.
That facility is not a regular warehouse. It is part of Walmart’s fresh grocery network, which handles products such as produce, dairy, eggs, flowers, and frozen items.
These products are among the items shoppers notice most quickly when something goes wrong.
If a retailer cannot move them efficiently, customers may see emptier shelves, fewer choices, or food that does not feel as fresh.
A high-tech perishable distribution center depends on refrigeration, sorting systems, automation, and constant power to keep food moving safely through the system.
So while the agreement sounds like an energy contract, the customer connection is more practical.
Walmart is trying to secure dependable power for the systems that help move fresh and frozen groceries through its network more efficiently.

Walmart says Illinois expansion supports jobs
The deal also strengthens jobs around Walmart’s Illinois expansion.
Walmart previously said it is building five new high-tech perishable distribution centers as part of a broader grocery-network transformation.
Those facilities will be in the following locations:
- Shafter, California
- Lancaster, Texas
- Wellford, South Carolina
- Belvidere, Illinois
- Pilesgrove, New Jersey
Collectively, Walmart said those facilities would bring about 2,000 new jobs to those communities and its supply-chain network.
This is important to Walmart because automation is often discussed as a threat to workers, and the retailer is trying to frame its supply-chain investment differently.
The company has said these newer facilities create roles tied to technology, equipment, and operations, including jobs that involve working with automated systems rather than traditional warehouse labor.
The Constellation agreement also supports existing energy-sector jobs. The companies said the Dresden Clean Energy Center supports more than 1,100 family-sustaining jobs and is licensed to operate through 2049 and 2051.
“Walmart’s commitment enables meaningful investment in the Dresden Clean Energy Center — bolstering reliability, sustaining local jobs and economic activity, and putting more dependable, emissions-free energy onto the Illinois power grid,” said Constellation Chief Commercial Officer Jim McHugh.
Walmart already has a large presence in Illinois, with about 175 stores and clubs and more than 55,000 associates.
Walmart is not only adding energy support for a distribution center. It is also linking a major Illinois grocery project to long-term power infrastructure and local employment.
Walmart tries to protect its low-price promise
For shoppers, Walmart’s value proposition is key.
Yet the retailer’s ability to offer low prices depends on more than negotiating with suppliers or running promotions. It also depends on how efficiently it can move goods through its network.
Fresh food is especially sensitive. It needs to be stored properly, moved quickly, and delivered to stores or pickup orders before waste increases. If that process becomes more expensive or less reliable, the pressure can eventually show up in prices, availability, or customer experience.
Walmart’s long-running promise has been to help customers save money. But in today’s retail environment, that promise increasingly depends on technology, logistics, and energy reliability.
The company’s latest move shows how far that strategy now reaches.
Walmart is using a nuclear power agreement to support a high-tech grocery distribution project. That project is tied to new jobs, fresh-food capacity, and the company’s effort to keep shelves stocked for shoppers who are watching every dollar.
