    Constellation and Vistra Expand Multi-Decade Nuclear PPAs with Hyperscalers

    Question

    Constellation and Vistra Expand Multi-Decade Nuclear PPAs with Hyperscalers

    Direct answer

    Hyperscale cloud operators Microsoft, Meta, and Amazon Web Services continue to contract large blocks of firm nuclear generation directly from independent power producers. Constellation Energy's portfolio of over 22 GW represents the largest operational nuclear base in the United States, providing significant contracting scale. Vistra's 6.4 GW nuclear portfolio continues to secure corresponding long-term commercial commitments, confirming that structural electricity demand from artificial intelligence workloads is driving multi-decade revenue visibility for unregulated baseload generators.
