Amazon locks in nuclear power for 20 years as energy demand surges

Key Points:

• Amazon has signed a 20-year agreement with Constellation Energy to secure 690 megawatts of nuclear power from the Calvert Cliffs Clean Energy Center in Maryland, including support for a 190-megawatt expansion expected by 2030-2032.
• The deal includes a retail electricity supply agreement covering Amazon's operations across the 13-state PJM market, helping Amazon manage energy costs while supporting reliable, carbon-free power for its data centers.
• This long-term commitment provides Constellation with revenue certainty to pursue license extensions for Calvert Cliffs' reactors, currently licensed through 2034 and 2036, and supports the plant's continued operation and expansion.
• Amazon's investment in nuclear energy aligns with its broader strategy to secure reliable, carbon-free power for its growing data center and AI infrastructure, building on previous investments in advanced nuclear technologies and small modular reactors.
• Calvert Cliffs, Maryland's only nuclear plant, produces up to 1,790 megawatts—enough to power over 1.3 million homes—and employs more than 800 people, with this agreement reinforcing its role in the regional clean energy grid.
