Google Partners with Nuclear Power Providers for Alabama and Tennessee Data Centers

August 20, 2025

A landmark agreement between Google, Kairos Power, and the Tennessee Valley Authority (TVA) will bring 50 megawatts of advanced nuclear energy to data centers located in tennessee and Alabama. This collaboration represents a critically important step towards meeting the escalating energy demands created by the rapid growth of artificial intelligence and solidifies the nation’s commitment to next-generation nuclear technologies.

The Rise of nuclear Energy for Data Centers

Under the terms of the agreement, Kairos Power’s Hermes 2 Plant, situated in oak Ridge, Tennessee, will supply up to 50 megawatts of power to the TVA grid, directly benefiting Google’s facilities.This marks the first instance of a utility procuring energy from a Generation IV (GEN IV) reactor, highlighting a paradigm shift in power sourcing for energy-intensive operations.

This growth builds upon an earlier agreement finalized in October, where Google committed to purchasing nuclear power from multiple small modular reactors currently under development by Kairos Power. The initial phase of the collaboration, slated to begin in 2030, aims to deliver a total of 500 megawatts of advanced nuclear capacity by 2035. This capacity is projected to power approximately 350,000 homes.

Addressing the AI-Driven Energy Surge

The surge in demand for electricity is inextricably linked to the expansion of data centers, particularly those supporting generative artificial intelligence applications. These data centers require vast amounts of power to operate, placing significant strain on existing energy infrastructure. A recent report from GridStrategies forecasts a 15.8% increase in U.S. electricity demand by 2029, driven by data centers, manufacturing, and the broader electrification trend.The International energy Agency anticipates that U.S. data center electricity consumption will jump an amazing 130% between 2024 and 2030.

This escalating demand has prompted other tech giants to explore nuclear energy solutions. microsoft, for example, has entered into a 20-year power purchase agreement with Constellation, possibly restarting the Three mile Island Unit 1 reactor in pennsylvania. Amazon has also announced multiple nuclear-focused deals with Energy Northwest, X-energy, and Dominion Energy, diversifying its energy portfolio to include clean, reliable nuclear power.

How does Google’s partnership with nuclear power providers contribute to it’s 24/7 carbon-free energy goal?

Securing Enduring Power for Growing cloud Demand

Google’s commitment to renewable energy has taken a significant step forward with new partnerships aimed at powering its expanding data center infrastructure in Alabama and tennessee. These aren’t typical renewable energy agreements; Google is directly collaborating with nuclear power providers to ensure a reliable, carbon-free energy supply. This move highlights a growing acceptance of nuclear energy as a crucial component of a sustainable energy future, particularly for energy-intensive operations like large-scale data centers. The increasing demand for cloud computing and AI services necessitates considerable power,and Google is proactively addressing this need with innovative energy solutions.

The Alabama & Tennessee data Center Expansion: A Power Perspective

Google has been steadily expanding its data center footprint across the US, with significant investments in both Alabama and Tennessee. These facilities are critical for supporting Google’s services – Search, Gmail, YouTube, Google Cloud, and increasingly, AI workloads.

Alabama: Google’s data center in Bridgeport,Alabama,is a major employer and economic driver for the region. The facility requires a consistent and substantial power supply.

Tennessee: Similarly, the data center in Clarksville, Tennessee, is a key part of Google’s infrastructure. The expansion plans necessitate securing long-term, reliable energy sources.

The challenge lies in meeting this demand sustainably. While solar and wind power are vital, their intermittent nature requires backup solutions. Nuclear energy offers a consistent baseload power source, making it an attractive option for data centers.

Why Nuclear Power for Data Centers? Addressing Reliability & Sustainability
