Google makes a fresh bet on nuclear power as the AI energy crunch intensifies

Constellation Energy's shares rose sharply after the company signed a power agreement with Google, with the contracted volume roughly equivalent to the output of a new nuclear reactor. The deal reflects a broader trend: AI data centers require vast amounts of round-the-clock electricity, and technology companies are increasingly turning to nuclear generation to secure reliable, low-carbon supply.

For investors, the arrangement highlights how AI demand is reshaping energy markets. Nuclear operators with existing fleets can sell long-term power contracts without building new plants, potentially improving revenue visibility. Utilities and independent power producers with nuclear assets may attract similar interest, though each deal's terms and duration matter for valuation.

What to watch: whether more technology companies follow with comparable agreements, how regulators treat these arrangements, and whether the interest in nuclear power translates into actual new capacity, which takes years to permit and build. The episode also underscores the growing link between AI infrastructure spending and electricity demand — a connection increasingly relevant across both sectors.
