From Constellation secures major power deals with Amazon and Alphabet

How could Constellation's nuclear capacity expansion deals affect PJM Interconnection?

Likely What happens if… A possibility worth considering, not a forecast.

PJM Interconnection may benefit from 890 megawatts of stable nuclear power The updates to Constellation's nuclear units, secured through deals with Alphabet and Amazon, will add 890 megawatts of new nuclear capacity. Since most of Constellation's nuclear assets operate on the PJM Interconnection grid, this influx of stable, carbon-free power will increase the overall capacity and reliability of the regional grid managed by PJM. This process involves modernizing turbines, steam generators, and controls at existing facilities in Illinois, Pennsylvania, and New Jersey.

Why it matters

For PJM Interconnection, the reliable addition of 890 megawatts of carbon-free power enhances the stability and capacity of the grid it manages. This stable power is crucial for meeting the growing demand from energy-intensive users, such as hyperscalers like Alphabet, who require firm, 24/7 power for AI data centers.

Constellation operates the largest nuclear fleet in the U.S., providing one-fifth of all nuclear capacity in the country. This large scale and scope position the company as a key provider of stable infrastructure, validating the role of nuclear operators in meeting the needs of major technology companies.
