China is on track to nearly double its data center capacity by the end of the decade, a rapid expansion fueled by artificial intelligence and high-performance computing that is reshaping both the country’s digital economy and its power system. New analysis from Rystad Energy indicates that an additional 28 gigawatts of data center capacity is expected to come online by 2030, building on the 32 gigawatts already installed, and pushing total electricity consumption from the sector to an estimated 289 terawatt-hours.
This surge would more than double current consumption levels and account for approximately 2.3% of China’s total electricity demand, marking a dramatic shift for a sector that until recently was considered a relatively small contributor to national energy use. The pace of growth is particularly striking, with data center power demand projected to increase at an annual rate of 19% between 2025 and 2030, making it the fastest-growing source of electricity consumption in the country.
Driving this expansion is the rapid rise of artificial intelligence and high-performance computing workloads, which require far greater processing power than traditional data center operations. Facilities designed for these advanced applications are significantly more energy-intensive, and their share of China’s total data center capacity is expected to climb from 39% this year to nearly half by 2030. This shift is fundamentally altering the scale and structure of the country’s digital infrastructure.
The growth is closely tied to China’s “East Data West Computing” strategy, launched in 2022 to redistribute computing resources away from densely populated eastern regions toward areas with more abundant land and energy resources. Major computing hubs have emerged in regions such as Inner Mongolia, where companies including Huawei, ByteDance, and 21Vianet are investing heavily in large-scale projects. These western hubs offer access to renewable energy sources, making them particularly attractive for energy-intensive AI workloads.
Industry analysts note that data centers are no longer a peripheral component of China’s power system but are becoming a structural driver of demand in their own right. Simeng Deng, a senior analyst at Rystad Energy, emphasized that the speed of AI-driven expansion is compressing timelines for both infrastructure deployment and energy procurement. Operators are increasingly prioritizing reliable and low-carbon electricity supplies, integrating wind, solar, and battery storage into their energy strategies even in the absence of strict regulatory mandates.
China’s overall electricity demand is still expected to grow, though at a slower pace than in previous years. Rystad Energy forecasts a compound annual growth rate of 3.9% through 2030, down from 6.5% during the previous five-year plan period. Within this broader slowdown, the contrast between sectors is becoming more pronounced. Industrial demand growth is set to decelerate significantly, while data centers continue to expand rapidly, increasing their share of national electricity consumption from 1.2% last year to 2.3% by the end of the decade.
Recognizing the strategic importance of the sector, the Chinese government has placed data center development at the center of its upcoming economic planning framework. The 15th Five-Year Plan, covering 2026 to 2030, emphasizes both efficiency and sustainability, introducing strict targets for power usage effectiveness, a key metric that measures how efficiently data centers use electricity. New facilities are already required to meet stringent thresholds, with some of the most advanced projects approaching global best-in-class efficiency levels.
Despite the push for greener operations, most data centers in China continue to rely heavily on the national grid to ensure uninterrupted power supply. The country’s extensive coal-based baseload and resilient grid infrastructure provide the stability needed to support rapidly growing digital workloads. However, the scale of expansion is also creating new opportunities to accelerate renewable energy adoption, particularly in designated computing hubs where projects are required to source a significant portion of their electricity from clean energy.
Operators are responding with a range of strategies, including the use of green electricity certificates, direct connections to offsite wind and solar farms, and the development of onsite generation capabilities. Many are combining multiple approaches to balance sustainability goals with reliability requirements, reflecting the complex energy demands of modern data centers.
Several projects highlight this evolving model. Large-scale computing bases are integrating renewable power with battery storage to create low-carbon or even zero-carbon operations. Companies such as China Mobile and Tencent are deploying hybrid energy systems that combine rooftop solar installations, grid power, and advanced storage solutions to support their expanding infrastructure.
As China accelerates its push into artificial intelligence and digital services, the rapid growth of data centers is emerging as a defining factor in the country’s energy transition. The challenge will be balancing the immense power requirements of this new digital economy with sustainability targets and grid stability. With demand rising at unprecedented speed, the decisions made in the coming years will not only shape China’s technological future but also have far-reaching implications for global energy markets and climate goals.
