Google goes nuclear to power its AI data centers, committing to buy 890 megawatts of energy from Constellation

What happened

Google has struck a 20-year power purchase agreement with Constellation Energy to buy 890 megawatts of nuclear energy. The deal targets powering Google’s expanding network of AI data centers with a large-scale, clean energy source. Constellation plans to invest over $4.3 billion in nuclear infrastructure as part of the partnership. This nuclear power commitment signals a shift in how Google intends to meet the massive energy demands driven by AI workloads.

Why it matters

AI data centers consume huge amounts of electricity, forcing cloud providers to rethink energy sourcing under rising regulatory and cost pressures for decarbonization. Nuclear power offers a stable, carbon-free supply that avoids the intermittency and land-use concerns of wind and solar. For operators building or running AI workloads, this move could ease pressure on utility grids and reduce risks of power interruptions or surcharges linked to renewable intermittency. It also tightens the energy supply chain around a proven technology, potentially raising the bar for other hyperscalers seeking reliable low-carbon power at scale.

What to watch next

The real test will be the execution and impact of this nuclear capacity boost on data center costs and availability. Watch for how this contract influences other cloud providers’ energy sourcing strategies and whether it accelerates new regulatory support for nuclear power projects near major tech hubs. Also pay attention to Constellation’s ability to deploy and operate nuclear plants efficiently, since delays or cost overruns could ripple back into Google’s AI infrastructure expenses. The partnership could shape investment flows toward nuclear and change the energy mix underpinning AI growth for years.
