Amazon has signed a 20-year nuclear power contract with Constellation to procure 690 megawatts (MW) of electricity from the Calvert Cliffs nuclear power plant in Maryland, with 190 MW of new capacity expected to come online between 2030 and 2032. Google has also signed an agreement to introduce an additional 890 MW of nuclear power capacity in the United States.
