Google Signs 3.59-Gigawatt Power Deal, Its Largest Ever, to Fuel AI Data Center Growth

Google signed a 3.59-gigawatt electricity procurement deal, its largest ever, to power its expanding network of AI data centers, the company announced in early October 2026.

Much of the power in the deal is linked to nuclear energy sources, continuing a trend among major technology companies that have turned to nuclear power to meet the steady, carbon-free electricity demands of AI infrastructure.

The scale of the deal reflects how much energy large language models and AI training workloads require. A single large AI training run can consume as much electricity as thousands of homes use in a year, and the demand grows as models become larger and more capable.

Google has been one of the most aggressive buyers of clean energy among major technology companies, but the 3.59-gigawatt deal dwarfs its previous procurement agreements. The company said the deal is part of its broader commitment to running its data centers on carbon-free energy around the clock.

Amazon has also committed more than $1 billion to communities hosting its data centers and finalized a 20-year nuclear power purchase agreement to upgrade Maryland's Calvert Cliffs facility. Microsoft and Meta have made similar moves, with nuclear power emerging as the preferred solution for tech companies that need reliable, large-scale clean energy.

The energy demands of AI have drawn scrutiny from environmental groups and local communities near data center sites. Critics argue that the rapid buildout of AI infrastructure is straining power grids and driving up electricity costs for residential customers.

Google's deal is expected to support data center operations across multiple regions. The company did not disclose the specific locations or the timeline for when the power will come online.
