Google strikes major nuclear power deal to fuel AI data centers with 50 megawatt capacity

Google, Kairos Power and the Tennessee Valley Authority have agreed to supply 50 megawatts of nuclear power to data centers in Tennessee and Alabama.

The companies say the deal will help meet rising U.S. energy demand and advance the nation’s role in next-generation nuclear power.

Under the agreement, Kairos’s Hermes 2 Plant in Oak Ridge will feed up to 50 megawatts into the TVA grid that serves Google’s facilities.

The deal makes TVA the first utility to purchase power from a GEN IV reactor. It also marks the first deployment of Hermes 2 under Kairos’ broader pact with Google to deliver 500 megawatts by 2035. Kairos plans to boost Hermes 2’s output from 28 to 50 megawatts beginning in 2030.

In October, Google signed a deal with Kairos to buy nuclear power from ‘multiple’ small mod
