Google's parent, Alphabet, is set to sign a multi-year nuclear power deal with Constellation Energy worth USD 1 billion or more. According to recent reports, the deal could be announced soon, but the final amount and power supply are still unclear. Both companies have refused to comment on the deal at this point. However, the move comes as Google needs more power for its growing AI data centers. Nuclear power can supply electricity around the clock, which makes it useful for large data centers.
Google has already made previous moves in the same sector. In 2025, it agreed to buy power from NextEra Energy to help restart the Duane Arnold nuclear plant in Iowa. It also agreed to support upgrades at two nuclear plants run by Southern Co. Other tech firms are moving in the same direction. Amazon has agreed to buy 690 megawatts from Constellation, while Microsoft is backing the restart of a reactor at the former Three Mile Island site.
AI data centers need huge amounts of electricity. They also need power for cooling the servers. As AI use grows, companies need a steady supply that can run day and night. This is why nuclear power is getting more attention. Building new nuclear plants can take years. Companies are instead looking at existing plants and upgrades that can add power sooner.

Google is no longer simply buying power from the grid. Long-term deals can give energy companies a more stable source of income. The same trend is visible across the tech industry. Google, Amazon and Microsoft are making direct deals with nuclear power companies. These deals give energy producers large customers for many years.
For Google, the move is about more than electricity; it is about making sure its AI systems have enough power to keep running as demand grows. The next phase of the AI race may depend not only on chips and models, but also on who can secure enough energy.
