Google locks 20-year nuclear deal for AI data centers

Google has agreed to buy nuclear power from Constellation Energy over 20 years, a move aimed at securing stable, carbon-free electricity for its AI data centers. The deal, announced today, allows Constellation to invest in new generation and transmission infrastructure.

The partnership reflects the scale of Google’s AI ambitions. Data centers already consume a significant share of electricity, and AI workloads are expected to drive demand higher. Earlier this month, we reported on startups raising funds to develop power-efficient and off-grid solutions—both responses to the same pressure.

Nuclear’s appeal for AI operators lies in its reliability, a contrast to wind and solar. But the long-term commitment also locks Google into a single energy source at a time when data center power needs are still evolving. The deal suggests Google is prioritizing scale and predictability, a calculation that could influence how other cloud providers approach energy contracts.

Constellation’s ability to finance the expansion may depend on backing from large operators, raising questions about whether similar deals will follow for startups or smaller companies. For now, the agreement signals that AI’s energy demands are shaping not just data center design but the broader power grid.
