Walmart Signs 15‑Year Nuclear PPA With Constellation to Buy Dresden Power
The agreement will fund efficiency uprates at Dresden to add output for a new Belvidere distribution center and point to rising corporate demand for reliable, low‑carbon baseload electricity.
Overview
- Constellation and Walmart announced the long‑term deal on Tuesday, June 23, 2026, under which Walmart will buy about 176 megawatts of emissions‑free electricity, environmental attributes and capacity from the Dresden Clean Energy Center.
- Supply is structured as two separate 15‑year contracts that begin in 2029 and 2030 and include roughly 30 megawatts of additional output tied to planned efficiency uprates at Dresden.
- The uprates are equipment and performance improvements that boost output from existing reactors rather than building new units, and the PPA helps justify Constellation’s targeted investment in those upgrades.
- Constellation says Dresden is licensed to run through 2049 and 2051 and supports more than 1,100 regional jobs, while the power from the uprates is expected to back Walmart’s planned high‑tech perishable distribution center in Belvidere, Illinois.
- Market coverage noted a modest uptick in Constellation’s stock after the announcement and analysts view the deal as part of a broader trend of large companies locking in nuclear supply for steady, low‑carbon baseload power.
