Google’s AI Dreams Are Going Nuclear
Google and Kairos Power push nuclear innovation to fuel AI-era energy demands on the TVA grid.

The U.S. nuclear industry has long been stuck in the past, plagued by massive cost overruns and delays. Now, Google and Kairos Power are trying to change that narrative with a bold move in Tennessee. By 2030, the tech giant and the nuclear startup plan to connect an advanced reactor to the Tennessee Valley Authority grid, a project that could mark the beginning of a new era for American energy.
A Historic Agreement
Google, seeking clean and reliable power for its data centers, has joined forces with Kairos Power to deploy the Hermes 2 reactor. The TVA has agreed to purchase 50 megawatts of electricity from the project, making it the first U.S. utility to sign an offtake deal with an advanced nuclear plant. That output, enough to power roughly 36,000 homes, will help feed Google’s facilities in Tennessee and Alabama.
The structure of the deal is groundbreaking. Rather than saddling consumers with the risk of experimental technology, Google and Kairos will absorb the financial burden. TVA’s role is to provide a guaranteed revenue stream through the purchase agreement, ensuring stability without exposing households to the first-of-a-kind costs.
