Claim under review / Power & capacity

Nuclear power is being revived to run data centres

Data-centre operators may be turning to existing and new nuclear plants for round-the-clock, carbon-free power.

Long-term nuclear contracting is expanding into a clear pattern among major technology firms. With Google joining Amazon in signing 20-year PPAs with Constellation Energy—spanning 890 MW across six sites—and Oracle sourcing power from Point Beach, hyperscalers are directly underwriting nuclear fleet expansions to secure continuous power. The evidence strongly supports the revival claim through firm corporate commitments rather than speculative plans. However, these multi-decade projects still face lengthy implementation schedules and regulatory reviews before new capacity actually reaches the grid.

Latest development: On October 6, 2026, Google signed a 20-year power purchase agreement with Constellation Energy to support 890 MW of nuclear capacity across six plant sites for data centers. Concurrently, reports confirmed Oracle agreed to take power from the Point Beach nuclear facility, and BWX Technologies' BANR microreactor was selected for a Canadian clean-energy project.

  2. On October 5, 2026, Amazon and Constellation signed a 20-year power purchase agreement to back improvements at Maryland's Calvert Cliffs nuclear plant. On the same date, the Department of Energy announced a conditional loan commitment of up to $4.2 billion for Vistra to uprate and modernize three nuclear plants in Pennsylvania and Ohio, adding 433 MW of capacity.

    The claim gains concrete support as hyperscalers commit capital directly to nuclear generation. Amazon's 20-year contract with Constellation and federal conditional loan backing for Vistra demonstrate both private customer demand and state support for extending and upgrading existing reactors. The evidence points to an emerging pattern of bilateral deals rather than speculative interest. However, Vistra's loan package remains conditional, and physical uprates require multi-year engineering work and regulatory oversight before new power reaches the grid, leaving project execution and timeline certainty as open questions.
