FollowingGoogle and Constellation Energy sign a 20-year power purchase agreement to add 890 MW of nuclear power capacity to the PJM grid.
Google and Constellation Energy have signed a 20-year power purchase agreement that will add 890 MW of nuclear power capacity to the PJM interconnected grid. Constellation Energy will invest approximately US$4.3 billion to fund the project.
The additional capacity is not achieved by building a new reactor from scratch, but is planned to tap more output from the 11 existing operating nuclear reactors in Illinois, Pennsylvania and New Jersey. The company aims to achieve this goal by upgrading turbines, steam generators and digital control systems, a process known in the industry as "elevate."
More efficient capacity expansion and job creation
Constellation Energy believes that "power boost" is a faster way to increase power supply than building new reactors from scratch. The joint project is expected to bring 890 MW of new capacity to the PJM grid, while supporting approximately 4,400 existing jobs and creating 7,200 new construction jobs during the expansion period.
Second larger power supply agreement being advanced in parallel
In addition to the nuclear power boost project, Google and Constellation Energy have signed a separate 15-year agreement to cover Constellation Energy's additional 2,700 megawatts of electricity in PJM's existing fleet. The deal aims to ensure that these power plants are economically viable and continue to operate, and avoid being forced out of the grid due to uneconomical reasons.
In addition, the agreement also includes a software cooperation component. Under the five-year technology alliance, Constellation Energy will use Google Cloud and the Gemini Enterprise AI platform in its operations. Areas of cooperation include site selection, network security and power flow modeling.
Advocates to regulators and users: Balancing affordability with grid reliability
Both companies emphasized that the deal will help improve power affordability and grid reliability. Amanda Peterson Corio, Google's global head of energy and power, said the company plans to support its business growth by investing in clean, reliable electricity and adding new capacity to the U.S. power grid.
Joe Dominguez, Chairman and CEO of Constellation Energy, pointed out that the collaboration could serve as a model of how technology companies can collaborate with the energy industry to expand the digital economy in a responsible manner. According to Constellation Energy, the agreement is also a response to the PJM's "Bring Your Own Power" proposal and is consistent with the White House's "taxpayer protection commitment."
These two initiatives aim to allow large electricity users to add new electricity supplies without incurring additional costs and avoid passing on costs to household users.
Another example of the influx of technology giants into nuclear energy
The deal is the latest in a series of similar arrangements in the near future, reflecting technology companies joining forces with the nuclear industry. Just a few days ago, Constellation Energy reached a similar agreement with Amazon, which committed more than $3 billion and provided 690 megawatts of power support for the Calvert Cliffs plant in Maryland. This is the first time Amazon has funded a nuclear power boost project.
Google currently has other nuclear energy cooperation agreements, including working with NextEra Energy to restart the Duane Arnold reactor in Iowa, which will be decommissioned since 2020. Other agreements involve upgrades to two power plants owned by Southern Co.
Microsoft also signed an agreement in 2024 to purchase nuclear power from the shuttered Three Mile Island plant. Constellation Energy plans to reopen the plant in 2027.
