Amazon’s 20-year power purchase agreement with Constellation Energy is a strategic move to secure long-term, reliable electricity for its growing infrastructure footprint, while helping fund more than $3 billion in upgrades and capacity expansion at a Maryland nuclear plant. For CIOs and technology leaders, the deal underscores how energy strategy is becoming inseparable from digital infrastructure planning—especially for AI, cloud, and data center growth—because power availability, price stability, and carbon goals can now directly shape technology roadmaps and operating risk.
