Google has struck one of the largest power agreements yet tied to the artificial intelligence boom, committing to a long-term deal with Constellation Energy that will help add the equivalent output of a new nuclear reactor to the nation’s largest power grid.
Under the agreement announced Tuesday, Google will support upgrades at 11 existing Constellation nuclear units in Illinois, Pennsylvania and New Jersey that are expected to create 890 megawatts of entirely new nuclear generating capacity. The first additional power is expected to reach the grid in 2028.
The 20-year agreement will help support more than $4.3 billion in Constellation investment. Google also entered a separate 15-year agreement covering another 2,700 megawatts of electricity from Constellation’s existing fleet, bringing the combined power covered by the agreements to 3,590 megawatts.
The deal reflects a much larger shift underway as artificial intelligence and rapidly expanding data centers drive electricity demand higher across the United States. Rather than waiting for entirely new nuclear plants to be built, energy companies are increasingly looking for ways to extract more electricity from reactors already operating by upgrading turbines, steam generators and other equipment.
The timing is particularly notable. Just one day earlier, the U.S. Department of Energy announced a conditional commitment of up to $4.2 billion to help finance nuclear upgrades at Vistra plants in Pennsylvania and Ohio. Those projects are expected to add another 433 megawatts of nuclear capacity while preserving nearly 4,000 megawatts of existing generation.
Google and Constellation are also expanding their technology partnership. Constellation plans to use Google Cloud and Gemini Enterprise in grid planning, power-generation optimization and infrastructure protection—meaning artificial intelligence will not only help drive the need for more electricity, but could increasingly be used to help manage the energy system supplying it.
The Readovia Lens
America’s AI buildout is rapidly becoming an energy story. The enormous computing infrastructure behind advanced AI requires reliable electricity around the clock, and nuclear power is increasingly emerging as part of the answer. Google’s latest agreement shows how the AI race is beginning to reshape not just technology, but the physical infrastructure that powers the country.
