KEY FACTS

Constellation announced on September 30 that it signed a 20-year nuclear power supply agreement with Amazon.
Under the agreement, Constellation will supply Amazon with 690MW of power, including 190MW of new capacity coming online between 2030 and 2032.
The deal will drive more than $3 billion in infrastructure investment in Maryland for upgrades to the Calvert Cliffs nuclear plant.

PHYSIX OBSERVATION

Tech giants are turning nuclear power from a conceptual procurement item into long-term contracts, directly locking in power sources and new capacity. For the industry, data center power demand is forcing a structural shift in energy supply; for users, the underlying cost of AI service expansion will depend more on clean baseload power, and electricity prices and grid pressure are worth watching.
