Google has now poured over $2 billion into its data center campus in Jackson County, Alabama, a facility that first opened its doors in 2018 with a roughly $600 million initial investment. The expansion reflects a broader trend among hyperscalers racing to build out the physical infrastructure needed to power an insatiable appetite for AI and cloud computing.
The Jackson County site sits on the bones of a decommissioned TVA coal plant.
Nuclear power enters the picture
In August 2025, Google secured a power purchase agreement alongside Kairos Power and TVA for up to 50 megawatts of electricity from the Hermes 2 advanced nuclear plant. That energy will feed Google facilities across Alabama and Tennessee.
Google’s nuclear play isn’t happening in a vacuum. Microsoft has struck deals to restart Three Mile Island’s reactor. Amazon has invested in nuclear energy startups.
