Google is entering a new long-term agreement to buy electricity from US nuclear power plants operated by Constellation, as it seeks more power for its data centers. The deal covers updates involving six nuclear plant sites in the United States and is structured as a 20-year power purchase arrangement, according to reporting.

The announcements come as Google faces rising electricity demand tied to the growth of artificial intelligence workloads and expanding data center operations. Across outlets, the motivation is presented as securing reliable, steady power while managing the energy requirements of compute-intensive services.

Outlets differ mainly on framing and reported scale. One source describes the arrangement as an effort to guarantee revenue for plant updates, while another focuses on the expected size of the procurement, with estimates suggesting the agreement could exceed $1 billion. A third highlights market reaction, noting that Constellation’s stock rises sharply and that the contracted supply could be comparable to the output of a new nuclear reactor, depending on how the deal is measured.
