Top 10 Advanced Reactor Deals: Meta’s 1, 121 MW Constellation PPA and Equinix’s 1, 000 MW Buy (2024-2026)

Hyperscale data center operators are fundamentally shifting their energy procurement strategies, moving beyond intermittent renewables to secure massive tranches of 24/7 carbon-free power. Analysis of major power agreements from 2024 to 2026 reveals that nuclear energy, including conventional and advanced reactors, has become a critical component for powering the immense and constant electricity demand driven by artificial intelligence. Landmark deals, such as Meta’s 1, 121 MW nuclear PPA with Constellation and Equinix’s 1 GW commitment to advanced nuclear sources, signal a definitive pivot toward firm, baseload clean energy. The dominant theme emerging for 2025 is this strategic focus on reliability, with companies like Google signing development agreements for next-generation Small Modular Reactors (SMRs) to guarantee future power supply, a trend underscored by Microsoft’s colossal 10.5 GW renewable energy partnership with Brookfield, which sets a new benchmark for the scale required.

Table: Top Data Center Power Agreements (2024-2026)

Data Center Power Sourcing: Hyperscalers Shift to 24/7 Nuclear and Renewables

The range of energy sources in these top-tier deals demonstrates a sophisticated evolution in procurement strategy. While massive solar and wind agreements remain foundational, such as Microsoft’s 10.5 GW plan with Brookfield and Google’s 1 GW solar PPA in Texas, there is a clear and growing emphasis on firm, 24/7 carbon-free power. This diversification into technologies like conventional nuclear (Meta’s 1, 121 MW PPA) and large-scale hydropower (Google’s 3 GW framework agreement) implies that simply matching annual energy consumption with renewable energy certificates is no longer sufficient. The relentless, non-negotiable power demand from AI workloads requires a baseload energy source that intermittent renewables cannot provide alone. This strategic pivot to a portfolio approach, blending different clean technologies, is becoming the standard for ensuring operational resilience and meeting aggressive corporate climate goals.

US Grid Impact: Google’s PJM, ERCOT, SPP Deals and Microsoft’s 10.5 GW Plan

The geographic concentration of these agreements is overwhelmingly within the United States, targeting key electricity markets where data center and AI development are expanding most rapidly. Google’s 1.17 GW portfolio deal with Clearway Energy Group specifically targets the SPP, ERCOT, and PJM grids, indicating a surgical approach to adding capacity where it is needed most. The extreme nature of this demand is highlighted by the August 2024 agreement for an unnamed tech giant, which involves restarting a mothballed nuclear power plant to supply 835 MW of dedicated capacity. This points to a growing realization that existing grid infrastructure is insufficient. While some international activity is present, such as Amazon’s 472 MW wind PPA in Finland, the sheer scale of the US-based deals confirms the nation’s central role in the global AI infrastructure build-out and the associated strain on its power systems.

1, 121 MW Nuclear Deal: Meta’s PPA Shows Shift to Commercially Proven Baseload

These installations reveal a dual-track approach to technology maturity. On one front, hyperscalers are making enormous investments in commercially proven, bankable technologies to meet immediate power needs. Meta’s PPA for the full 1, 121 MW output of the Clinton Clean Energy Center and Google’s 3 GW hydropower agreement represent a commitment to existing, large-scale baseload assets. Simultaneously, these same companies are placing strategic bets on the next wave of energy technology. Google’s Master Plant Development Agreement with Kairos Power for 500 MW of advanced SMRs and Equinix’s 1 GW procurement from partners like Oklo and Radiant are forward-looking moves. This demonstrates a portfolio strategy: de-risking current operations with mature technologies while actively funding and securing a pipeline of future, more flexible advanced nuclear solutions to power long-term growth.

Google’s 500 MW Advanced SMR Plan: Kairos Power Deal Signals Future Power Strategy

Looking ahead, the most critical strategic development will be the acceleration of direct partnerships between hyperscalers and advanced nuclear developers. Expect to see a move away from simple offtake from existing plants and toward co-development agreements that give tech giants a first-mover advantage and a direct hand in shaping the deployment of next-generation reactor capacity.

• Signal Gaining Traction: The procurement model is evolving from buying power to funding new builds. Google’s September 2025 “Master Plant Development Agreement” with Kairos Power for up to 500 MW of advanced SMR capacity serves as a blueprint for this deeper integration between energy user and provider.
• Signal Gaining Traction: Data center operators are diversifying their technology bets within the advanced nuclear space to mitigate development risk. Equinix’s August 2025 move to sign agreements with a portfolio of developers—including Oklo, Radiant, and Bloom Energy—for 1 GW of power shows a preference for a multi-vendor strategy rather than dependence on a single next-gen reactor design.
• Signal Losing Steam: A strategy based solely on intermittent renewables is proving inadequate for the 24/7 demands of AI infrastructure. While deals like Microsoft’s landmark 10.5 GW renewable plan continue, they are increasingly being announced alongside firm power solutions like nuclear, signaling that a renewables-only approach is no longer viewed as a complete or resilient long-term strategy.
