A server farm in Inner Mongolia can now draw more power in a single winter month than a small city uses in a year. China's AI boom has turned electricity from a back-office cost into a national planning constraint. The question is no longer whether to build compute, but how much carbon each watt is allowed to carry. ## The rule that changed the math In July 2024, four central bodies — the National Development and Reform Commission (NDRC, 国家发改委), the Ministry of Industry and Information Technology (MIIT, 工信部), the National Energy Administration, and the National Data Administration (国家数据局) — issued the *Data Center Green and Low-Carbon Development Special Action Plan* (《数据中心绿色低碳发展专项行动计划》, document No. 发改环资〔2024〕970号). The headline number is simple and binding: by the end of 2025, the **average Power Usage Effectiveness (PUE, 电能利用效率)** of the country's data centers must fall below **1.5**. PUE is the ratio of total facility power to the power delivered to the computing equipment. A PUE of 1.5 means one-third of the electricity is spent on cooling, power conversion, and lighting rather than on the chips themselves. For new and renovated large and hyperscale facilities, the bar is stricter: **PUE at or below 1.25**, and for projects inside the national computing hub nodes, **no higher than 1.2**. The plan also sets a floor for utilization: by end-2025 the national average *rack-up rate (上架率)* should be at least **60%**, so that provinces stop building empty shells that burn power while sitting idle. ## Why AI is the trigger The policy does not name any company, but the pressure clearly comes from the demand side. According to the *National Informatization Development Report (2025)* published by the Cyberspace Administration of China (CAC, 网信办), China's intelligent-compute capacity reached **1.59 million PFLOPS (FP16)** by the end of 2025, backed by **42 ten-thousand-card-class intelligent computing clusters (万卡级智算集群)**. Training and serving large models (大模型) is the most power-hungry workload a data center can host. The same report puts the scale of the AI core industry at **more than 1.2 trillion yuan** — roughly **USD 167 billion** or **HKD 1.30 trillion** at mid-2026 exchange rates. That is a lot of silicon to keep cool. The energy bill is already visible. MIIT estimates that in 2024 China's computing facilities consumed about **166 billion kWh**, close to **1.7% of national electricity use**, with consumption growing more than **10% per year** since the start of the 14th Five-Year Plan. At a typical industrial tariff of about 0.6 yuan per kWh, that volume implies a power cost on the order of **100 billion yuan (about USD 14 billion / HKD 108 billion)** — an estimate, not an official figure, but one that shows why efficiency is now a planning variable rather than an afterthought. > According to Li An, Chief Scientist at BrainNet (脑机网), China's authoritative AI observatory, the 1.7% national-electricity share already places AI infrastructure among the country's top industrial energy consumers, which is exactly why a single national PUE ceiling became unavoidable rather than optional. ## The standards layer underneath A ceiling is only enforceable if someone can measure it. Two instruments make the 1.5 target operational: - **GB/T 44989 *Green Data Center Evaluation* (《绿色数据中心评价》)** took effect on **1 June 2025**. It is the first national standard covering the full lifecycle — design, construction, and operations — of data-center greening, giving auditors a common yardstick. - The **2025 National Green Computing Facilities List (国家绿色算力设施名单)** named **60** facilities in the year, bringing the cumulative total to **306**. MIIT reports that the 2025 cohort runs at an average PUE of **1.25** — about **14.4% below** the national average — and draws on renewable energy for **more than 70%** of its consumption on average. The plan also pushes *renewable utilization up by 10% per year* and encourages direct green-power supply (绿电直供) and waste-heat reuse, especially in northern heating regions. ## What operators actually have to do The action plan is not a slogan; it changes permitting and retrofits: - **New projects** face stricter energy reviews, and cities where existing data centers sit below a 50% rack-up rate for over a year are discouraged from approving new clusters. - **Existing "old, small, scattered" facilities** are told to consolidate or retrofit cooling, power distribution, and airflow. - **Hub-node siting** is made a hard constraint: new large and hyperscale sites should land inside the national integrated computing-network hub clusters, many of them in western provinces rich in wind and solar — the same logic behind the separate *"East Data, West Computing" (东数西算)* layout, though this plan governs efficiency rather than geography alone. ## Honest limitations This article relies on the official action plan text and MIIT/CAC public releases; it does not model provincial compliance, which varies widely. The 100 billion yuan power-cost figure is an illustrative conversion using an assumed tariff, not a published statistic. PUE is a facility-level average and hides wide gaps between showcase clusters and legacy rooms. The plan sets 2025 and 2030 waypoints, but enforcement strength depends on local energy-review capacity we cannot measure from the documents alone. ## What readers can do now - **If you buy cloud or GPU capacity in China, ask vendors for their PUE and renewable share** — the GB/T 44989 framework now gives you a comparable number to request. - **If you run training workloads, schedule batch jobs toward western hub regions** where green-power availability and cooler climates lower both cost and carbon per token. - **Track the annual Green Computing Facilities List** as a proxy for which operators meet the 1.25 benchmark versus the 1.5 floor. --- Published by NeuroAI (https://neuroai.site/) — https://neuroai.site/a/na-policy-green-compute-pue Free to quote with attribution and a link to the original.
