How could Constellation's long-term power deals affect Amazon Web Services?
AWS may benefit from stable, long-term power supply secured by Constellation The 20-year power purchase agreement signed between Constellation Energy and Amazon secures a dedicated supply of 690 megawatts of power for Amazon's operations. This deal also includes Amazon helping to fund a 190-megawatt uprate at Constellation's Maryland nuclear power plant, Calvert Cliffs Clean Energy Center, with new capacity expected between 2030 and 2032. This guaranteed, long-term energy source provides operational visibility and a floor for earnings for Constellation, while ensuring that Amazon's data centers, which power AWS, have a stable and predictable energy foundation for the next two decades.

How it reaches Amazon Web Services
-
Constellation Energy secured two major 20-year power purchase agreements (PPAs) with large technology companies. On September 30, the company signed a PPA with Amazon for 690 megawatts of power. A week later, Constellation locked in a similar agreement with Google, which will support the commissioning of 890 megawatts of new nuclear capacity in the PJM Interconnection region.
The full event1independent outlet -
By securing long-term, dedicated power capacity and funding upgrades, Constellation provides a stable energy source necessary to meet the high and growing power demand of Amazon's data centers, which are the operational backbone of Amazon Web Services.

Why it matters
For Amazon Web Services, the ability to secure massive, long-term, and stable power is critical to its operational viability and cost structure. Data centers are extremely power-intensive, and securing a 20-year agreement with a major independent power producer like Constellation reduces the risk associated with volatile energy markets and fluctuating supply, which is a major operational concern for hyperscalers.
This deal is part of a broader trend where major hyperscalers, including Amazon and Google, are scrambling to secure large amounts of power to fuel their AI and data center buildouts. By locking in this supply, Amazon is transforming its energy risk from a variable market exposure into a predictable, contracted cost, which is vital for maintaining competitive pricing and reliability for AWS customers.
