    Constellation and Vistra secure multi-decade nuclear PPAs with hyperscalers

    Question

    Constellation and Vistra secure multi-decade nuclear PPAs with hyperscalers

    Direct answer

    Data center operators are securing baseload nuclear generation via long-term contracts. Constellation Energy, with a 22 GW fleet, has locked in 20-year agreements with Microsoft and Meta, while Vistra has signed contracted capacity from its 6.4 GW portfolio to Meta and Amazon AWS. These agreements establish guaranteed pricing floors and premium realizations above prevailing wholesale grid prices, insulating independent power producers from fuel price volatility while answering data center reliability requirements.
