    Datacenter Power Demand Catalyzes 20-Year Nuclear PPAs for CEG and VST

    Question

    Datacenter Power Demand Catalyzes 20-Year Nuclear PPAs for CEG and VST

    Direct answer

    Constellation Energy and Vistra are capturing substantial commercial premiums by signing 20-year power purchase agreements directly with hyperscalers including Microsoft, Meta, and Amazon Web Services. With Constellation operating 22 GW and Vistra operating 6.4 GW of nuclear assets, these operators provide non-intermittent baseload electricity. As forecasts project a 60% expansion in aggregate U.S. power demand by 2045, long-term contracting removes merchant pricing volatility and establishes utility generators as critical infrastructure suppliers to AI compute clusters.
