China’s rapid expansion of artificial intelligence infrastructure is pushing technology companies toward new energy strategies, with Alibaba reportedly exploring the use of small modular reactors (SMRs) to supply electricity for its data centers.
The discussions highlight a growing global challenge for the digital economy: securing reliable, low carbon power for energy intensive computing operations while navigating regulatory and economic constraints.
According to industry sources cited by China Business Journal, Alibaba has approached a Chinese state owned nuclear power enterprise to examine the feasibility of deploying SMRs for its Renhe Data Center in Hangzhou, Zhejiang Province. The facility, one of the earliest cloud computing data centers in the region, supports AI focused companies including BrainCo Technology and Lingban Technology.
The potential project reflects the rising electricity demand associated with AI workloads. Training and operating advanced AI models require large computing clusters that consume significantly more electricity than traditional digital services. As technology companies expand data center capacity, access to stable power has become a strategic consideration alongside chip availability and computing infrastructure.
However, the discussions between Alibaba and the nuclear enterprise remain constrained by China’s electricity market structure. The challenge is not only whether SMR technology can provide power, but whether the regulatory system allows that power to be delivered in a commercially viable way.
Data centers require continuous electricity supply, making reliability a critical factor in their energy strategy. Renewable energy sources such as solar and wind can reduce emissions but introduce variability, creating demand for additional balancing solutions, storage, or firm generation.
Nuclear power has attracted attention from technology companies because it can provide stable baseload electricity without direct carbon emissions during operation. SMRs are particularly discussed as a potential option because they are designed to have smaller capacities than conventional reactors, standardized manufacturing processes, and potentially shorter construction timelines.
For AI data centers, the appeal of SMRs lies in their ability to provide dedicated electricity and potentially heat services. Some SMR designs are intended not only for power generation but also for industrial heat applications, desalination, and district energy systems.
However, the technology remains at an early commercial stage in many markets. Large scale deployment depends on regulatory approval, construction experience, cost competitiveness, and supply chain development.
The main obstacle facing a potential Alibaba SMR project is linked to China’s centralized electricity system. Under the current grid structure, electricity generated by power plants, including privately developed facilities, generally must enter the public grid before reaching consumers. This means a company cannot simply build an independent nuclear facility and directly supply electricity to its own data center under a fully isolated model.
The reported concern is that if SMR generated electricity must be transmitted through the public grid and priced at around RMB 0.58 per kilowatt hour, the cost advantage of dedicated nuclear generation could become limited.
A nuclear industry source suggested that a more flexible model similar to self supply power plants would be needed for data center applications to become economically attractive. Yet current regulations restrict fully independent operation, creating uncertainty over how technology companies could directly benefit from owning or financing nuclear assets.
In January 2026, CNNC (Xiangshan) Nuclear Energy Co., Ltd. was established with registered capital of RMB 250 million. Among its shareholders is Shanghai Yiqi Network Technology Co., Ltd., a company fully owned by Alibaba Cloud Computing Co., Ltd. The connection suggests that Alibaba has been positioning itself to participate in nuclear energy development, particularly as electricity demand from cloud computing and AI services continues to grow.
Technology companies globally are increasingly exploring direct energy partnerships as electricity becomes a strategic input. Similar discussions have emerged around renewable energy procurement, long term power contracts, and advanced nuclear technologies.
For hyperscale data center operators, energy supply is becoming a competitive factor. Companies that secure reliable and predictable electricity sources may gain advantages in deploying AI infrastructure at scale.
The first challenge is technology maturity. While SMR concepts have existed for decades, commercial deployment remains limited compared with traditional nuclear reactors. Developers must demonstrate consistent operation, cost competitiveness, and manufacturing scalability.
Project approval is another major factor. Nuclear facilities require extensive safety assessments, licensing procedures, and regulatory oversight. These processes are necessary but can extend development timelines.
Economic viability also depends on electricity pricing structures. Even if SMRs achieve technical performance targets, their competitiveness depends on whether electricity markets allow producers and consumers to capture the benefits of dedicated supply arrangements.
