Google reportedly nears $1bn-plus nuclear power deal with Constellation

Alphabet’s Google is close to an agreement to buy nuclear power from Constellation Energy, Bloomberg reported on Monday.

Under the multi-year deal, Google would pay Constellation $1bn or more, according to people familiar with the talks.

Bloomberg said an announcement may come this week. Yet, Constellation declined to comment to Reuters.

Constellation runs more US nuclear reactors than any other company. Bloomberg did not say which of its plants would supply Google or how much electricity the deal would cover.

Google has been adding nuclear power to supply its data centres all year. Last month, it agreed to help pay for upgrades at two Georgia Power nuclear plants, Vogtle and Hatch, which could add about 96 megawatts of capacity.

That deal still needs approval from Georgia’s utility regulator, the Atlanta Journal-Constitution reported.

In Iowa, Google is also the buyer for the Duane Arnold plant, which NextEra Energy is bringing back into service. The US government closed a $1.9bn restart loan for that project in September.

Constellation, for its part, already sells nuclear power to other large technology companies. In 2024, Microsoft signed a 20-year deal to restart a unit at Three Mile Island in Pennsylvania.

A year later, Meta agreed to buy the Clinton plant’s full output in Illinois starting in 2027. Amazon has also signed a power deal with the company.

Demand from AI is behind the rush. Data centres need electricity around the clock, and nuclear plants can supply it steadily without carbon emissions, unlike wind and solar.

Google has also joined Nvidia in an industry alliance to make data centres adjust their power use when grids are under strain.
