Google Signs 20-Year Power Purchase Agreement with Constellation Energy
Google has signed a 20-year power purchase agreement with Constellation Energy to upgrade existing nuclear power units, adding 890 megawatts of nuclear capacity, which is expected to create approximately 7,200 construction jobs during the construction period.
The agreement covers 11 units across six sites in Illinois, Pennsylvania, and New Jersey, achieving power upgrades through the replacement of turbines, steam generators, and control systems. The first upgrade is expected to be completed by 2028, with all units operational by the end of 2032.
Constellation will invest over $4.3 billion, which is equivalent to a large new reactor, but the delivery speed is much faster than building from scratch.
The agreement also maintains about 4,400 existing jobs and supports local high-skilled union maintenance, engineering, and operations work.
The electricity will be injected into the PJM grid, serving approximately 67 million people across 13 states, with Google as the primary buyer, and upgrade costs will not be passed on to other users.
The two parties also signed a 15-year agreement covering 2,700 megawatts of existing units and extended a five-year technical alliance, with Constellation deploying Google Cloud and Gemini for optimized operations.
Funding is secured through Google’s long-term power purchase agreement, directed towards nuclear upgrades and grid capacity, benefiting nuclear operators and construction jobs while alleviating electricity pressure on data centers.

Google has previously collaborated with other nuclear projects, including the restart of the Duane Arnold nuclear power plant in Iowa and the Loviisa nuclear power plant in Finland, raising the newly added nuclear capacity in the U.S. through upgrades and restarts to over 1.5 gigawatts. Constellation has also signed a similar upgrade agreement with Amazon at the same time.
On the capital front, Google provides revenue certainty for Constellation's $4.3 billion unit upgrades through long-term power purchase agreements, directing funds towards power upgrades of existing nuclear assets rather than new reactors. Both parties will also integrate Google Cloud and Gemini into plant operations, creating a two-way binding of power procurement and technology output.
Similar cases include Microsoft and Constellation restarting the Three Mile Island unit, Amazon supporting the expansion of Calvert Cliffs, and tech companies locking in renewable energy through long-term PPAs. We are currently in a phase where large tech companies drive the expansion of existing nuclear power through power purchase agreements to meet the load of AI data centers.
This essentially represents a restructuring of the industrial chain: the demand for electricity from AI drives tech companies to directly intervene in the power supply side, rapidly increasing baseload power through upgrades of existing nuclear units, with pricing power and capacity decisions shifting from traditional utility planning to bilateral agreements dominated by large electricity consumers and nuclear operators.
