June 23 (Reuters) – Retail bellwether Walmart has signed a long-term nuclear power purchase agreement with ​Constellation Energy, the companies said ‌on Tuesday.

Under the agreement, Constellation Energy will supply nuclear power from its Dresden Clean Energy Center in Illinois ‌to ​Walmart’s previously announced “high-tech” ⁠perishable distribution center, currently ⁠in development in Belvidere, Illinois.

• Walmart will buy about 176 megawatts of electricity, including 30 megawatts ​of additional output from planned upgrades, under two 15-year ⁠contracts starting in ⁠2029 and 2030.

• The agreement ​is among the first between a ​major U.S. retailer and a ‌nuclear energy provider and underscores growing corporate interest in baseload clean power, which can provide electricity ⁠around the clock.

• The deal would support investment in efficiency upgrades, or uprates, ⁠at the ‌Dresden Clean Energy Center, ⁠allowing the plant to ​increase ‌output without building new ​generation capacity.

• ⁠Dresden, one of Constellation’s largest nuclear plants, is licensed to operate through 2049 and 2051.
