Amazon signs 20-year nuclear PPA with Constellation
· Energy · United States
Amazon signed a 20-year power purchase agreement with Constellation that will add 190 MW of capacity and extend the operating life of the Calvert Cliffs nuclear plant in Maryland. The deal ties a major tech buyer directly to existing nuclear output.
Why it matters：It is another sign that data-centre demand is pushing tech firms to contract long-term nuclear supply, a trend that could support life extensions and new capacity worldwide.
Key points
- The PPA runs for 20 years.
- It enables 190 MW of added capacity.
- Calvert Cliffs is in Maryland, US.
