Google signs nuclear energy deal for data centers

Summary

Google has signed a 20-year, $4.3 billion nuclear energy purchase agreement with Constellation. The deal adds 890 MW of capacity through 11 reactors at six facilities in the US. Additionally, a separate 2,700 MW all-fuels supply agreement was concluded. Both contracts are tied to the PJM grid, which is already under strain due to rising demand from AI data centers.

Why it matters

AI data centers are pushing the PJM Interconnection grid toward its reliability limits. Complaints filed with FERC and a recorded 54% rate increase in New Jersey serve as evidence of this. Google’s decades-long nuclear commitment represents one of the largest corporate investments to secure baseload power by upgrading existing reactors. However, the parallel all-fuels agreement implies that a significant portion of the contracted electricity will still come from gas and oil, complicating the clean energy narrative.

Highlights

• 890 MW of new nuclear capacity within five years through upgrades to 11 existing reactors in Illinois, Pennsylvania, and New Jersey. This is equivalent to the capacity of one large reactor or three SMRs.
• A separate 15-year, 2,700 MW supply agreement covers Constellation’s all-fuel mix, which includes 22% gas/oil.
• Google is locking in long-term energy contracts while its own carbon emissions rose by 18% and electricity demand increased by 37% last year.

Critical take

The headline sells a nuclear success story. However, the much larger 2,700 MW agreement explicitly includes gas and oil production. Therefore, the situation implies locking in fossil fuel dependency as much as it does a clean energy gain. Add to this Google’s 18% increase in carbon emissions. The framework of 'nuclear-hungry, high-consumption data centers' reads less like a sustainability breakthrough and more like a demand problem being offloaded to the grid.
