AI data centers are pushing electricity demand to a new scale, and Big Tech is turning to nuclear power to secure reliable, round-the-clock energy. In 2026, nuclear commitments from major hyperscalers including Meta, Microsoft, Google, and Amazon have reached more than 9.8 GW, with announced deals and investments running into tens of billions of dollars. From reactors and turbines to cooling, electrical, and safety systems this surge is creating new demand across the nuclear power plant equipment market.
Why AI Data Centers Need Nuclear Power
To run GPUs, servers, cooling systems, and networking equipment AI data centers require a large and steady supply of electricity. Unlike traditional facilities, AI workloads can operate continuously, creating high power demand throughout the day and night. That’s why 24/7 baseload power is critical to powering computing systems reliably without interruption. Data center operators need power sources that can provide a steady stream of power, but also meet the growing demand for computing power as AI adoption continues to grow.
Nuclear power can provide continuous electricity with high reliability, making it a potential option for large AI data centers. Interest is also growing in SMR equipment, which could support smaller and more flexible nuclear projects. At the same time, demand for nuclear reactor components may increase as more companies explore nuclear power for data centers and other energy-intensive facilities.
Key Growth Drivers
The growing electricity needs of AI data centers are creating new demand for reliable and continuous power. To support their expanding computing infrastructure hyperscalers are exploring long-term nuclear agreements and investing in new nuclear capacity. At the same time, SMR development is creating opportunities for equipment manufacturers and suppliers of nuclear reactor components.
Hyperscaler Power Purchase Agreements
To secure nuclear electricity for data center operations major technology companies are entering long-term agreements. These arrangements can provide stable power while helping companies plan for rising electricity demand from AI workloads. Across the nuclear supply chain increasing interest in nuclear power for data centers is also creating opportunities. Power purchase agreements can help support investment in existing nuclear plants and encourage new generation capacity. These agreements could boost demand for nuclear power generation and associated infrastructure as more hyperscalers seek reliable low-carbon power.
SMR (Small Modular Reactor) Development
Small modular reactors are being considered as a possible solution to providing reliable power to large energy consumers. Their smaller size and modular construction may provide more flexibility than large scale nuclear projects of the past. For SMR equipment, including reactor systems, turbines, cooling systems, electrical equipment, and safety components growing SMR development is creating demand. Technology companies and energy providers are exploring how SMRs could eventually support data centers with dedicated power. The pace at which SMRs can move from development to deployment will depend on ongoing regulatory progress, project financing and commercialization.
Recent Big Tech Nuclear Deals
Major technology companies are moving from interest in nuclear power toward long-term agreements and investments. Microsoft has a 20-year agreement with Constellation Energy linked to the restart of Three Mile Island Unit 1, providing about 835 MW. (Source: constellationenergy.com).
Google has an agreement with Kairos Power for 500 MW of advanced reactors, while Amazon has invested in X-energy's SMR program and plans up to 960 MW. Meta has announced agreements involving existing nuclear plants and advanced reactors, with potential capacity reaching several gigawatts. (Source: kairospower.com)
These deals have implications beyond electricity procurement. While supporting investment in nuclear reactor components and supply chains these deals can create demand for SMR equipment, including reactor systems, turbines, cooling systems, and electrical infrastructure. The mix of existing-plant expansions, reactor restarts, and new SMR projects also shows that hyperscalers are pursuing multiple approaches to secure reliable nuclear power for data centers.
Challenges to Scaling Nuclear for Data Centers
To get approved and built, nuclear projects can take many years. Project timelines can be delayed by permits, safety reviews and construction. The availability of nuclear reactor parts can also influence the completion date of new plants. This can be a challenge for data center operators that need power as demand for AI surges.
SMRs also face commercialization risks. Many projects are still under development or moving through regulatory approval. As projects progress costs and timelines may change. Grid interconnection is another challenge. New plants need suitable grid connections to deliver electricity to data centers. These factors can affect demand for SMR equipment and the nuclear supply chain more broadly.
Market Outlook, 2026–2034
The nuclear power plant equipment market was valued at USD 21.25 billion in 2025 and is projected to reach USD 28.06 billion by 2034, growing at a 3.14% CAGR from 2026 to 2034, according to Polaris Market Research. The market includes reactor island equipment, turbine island equipment, auxiliary equipment, and instrumentation and control systems.
Growing investment in advanced reactors and SMRs can support equipment demand through 2034. Polaris also estimates the SMR market will grow from USD 7.05 billion in 2026 to USD 15.87 billion by 2034, at a 10.66% CAGR. These nuclear investments could create additional opportunities for reactor equipment and related infrastructure as AI data centers look for reliable power.
