Top 10 SMR Deals: Meta’s 6.6 GW, AWS’s $18 B Talen Deal, and Who Leads Data Center Capacity (2025-2026)

Hyperscale data center operators are aggressively securing nuclear power to meet the immense energy demands of artificial intelligence, marking a strategic shift toward firm, carbon-free energy. An analysis of agreements from 2025 and 2026 reveals that major tech firms and specialized developers are moving beyond renewable power purchase agreements to lock in long-term, 24/7 baseload power from both existing and next-generation nuclear reactors. Key indicators of this acceleration include Meta’s landmark commitment to 6.6 GW of nuclear capacity and Amazon Web Services’ (AWS) agreement with Talen Energy valued at up to $18 billion. The dominant market theme is the transformation of nuclear energy from an ESG consideration into a critical infrastructure component for AI growth, with hyperscalers now acting as anchor customers for Small Modular Reactors (SMRs) and advanced nuclear technologies.

Table: Top 10 Nuclear Power Commitments for Data Centers (2025-2026)

22+ GW Total Capacity Signals Broad Nuclear Adoption

The diversity of agreements signed in 2025 and 2026 demonstrates a multi-faceted strategy for nuclear adoption across the tech industry. These deals are not monolithic; they range from straightforward Power Purchase Agreements (PPAs) with existing nuclear plants to complex, long-term development partnerships for SMRs and advanced reactors. For instance, the 1.92 GW PPA between AWS and Talen Energy provides immediate, large-scale carbon-free power from an existing asset. In contrast, Meta’s 6.6 GW portfolio includes agreements with advanced reactor developers like Terra Power and Oklo, indicating a long-term strategy to secure a future pipeline of next-generation nuclear energy. This portfolio approach allows companies to de-risk their energy supply, balancing immediate needs with future technological advancements.

US Leadership, TVA and Constellation Power SMR Data Centers

The current wave of nuclear-for-data-center deals is almost exclusively an American phenomenon. Every major agreement listed, from Meta’s deals in January 2026 to the Fermi Hypergrid announcement in August 2025, is based in the United States. This geographic concentration is driven by a convergence of factors: the presence of the world’s largest hyperscale companies, a mature regulatory framework under the NRC, and the active involvement of established energy utilities. The Tennessee Valley Authority (TVA) has emerged as a particularly crucial player, partnering with both ENTRA 1 Energy on a 6 GW SMR program and with Google and Kairos Power on an advanced reactor project. This suggests that regions with established nuclear expertise and proactive utility partners are becoming magnets for data center investment.

Microsoft’s 2.5 GW Portfolio Highlights Diverse SMR Tech Maturity (2025-2026)

The agreements highlight a clear spectrum of technological maturity. On one end, deals like Microsoft’s 835 MW PPA with Constellation to power the Three Mile Island restart leverage commercially proven, existing large-scale reactors for immediate, reliable power. This represents the lowest-risk approach. In the middle are SMRs like the Nu Scale Power Module™, which are on the cusp of commercial deployment and are being anchored by large commitments from developers like ENTRA 1 Energy. On the forward-looking end are the advanced and micro-reactor designs from companies like Terra Power, Kairos Power, and Oklo. By investing across this spectrum, hyperscalers like Microsoft and Meta are not only securing their own power but are also catalyzing the entire advanced nuclear sector, helping bridge the “valley of death” for new technologies.

Scenario Modelling: SMR Co-location, Microsoft’s >$1 B Investment in Next-Gen Nuclear

The most critical strategic evolution for the sector is the move away from grid-based PPAs and toward direct co-location of nuclear reactors with data center campuses. This “behind-the-meter” model offers superior power reliability, cost predictability, and independence from an increasingly strained grid. The market is rapidly advancing toward this paradigm, with dedicated nuclear-powered data campuses becoming the next frontier.

• The clearest signal is Talen Energy’s Cumulus Data campus, which is directly connected to the 2.5 GW Susquehanna nuclear plant and has secured AWS as an anchor tenant.
• AWS’s separate announcement in October 2025 of its intent to develop its own SMR facility confirms that hyperscalers are considering becoming power producers, not just consumers.
• The emergence of specialized developers like ENTRA 1 Energy and the Fermi Hypergrid Campus, which are planning gigawatt-scale nuclear parks specifically to serve data centers, underscores this trend.
• Meta’s deep partnerships with SMR and advanced reactor firms like Oklo and Terra Power suggest a long-term vision of integrating purpose-built reactors directly into its future infrastructure footprint.
