Amazon has signed a 20-year power purchase agreement (PPA) with Constellation Energy to expand and renovate Maryland’s Calvert Cliffs nuclear plant, enabling $3 billion in investments, an additional 190 MW capacity, and relicensing the plant for two more decades. This deal supports carbon-free energy supply in the PJM grid region and helps Amazon manage energy costs for its facilities.
