Chengdu,Sichuan, China-September 17, 2026
The Flip Side of Exploding Computing Power: Uncontrolled Power DemandIn 2025, power consumption of national computing centers rose by 18.1% year-on-year, 3.5 times the growth rate of overall social electricity use. By 2030, computing centers will account for roughly 6% of the country’s total electricity consumption.This is not the most staggering figure. The power consumption per rack in traditional data centers normally ranges from 5 to 8 kW. In contrast, AI training racks, densely packed with GPU accelerator cards, see their power draw multiply by 5 to 8 times, hitting 20–40 kW.An intelligent computing center equipped with 1,000 AI racks carries an IT load of over 20 MW — excluding supporting facilities such as cooling and lighting systems.To put this into perspective: a 20 MW power demand equals the total electricity consumption of a town with 20,000 residents. As of 2026, more than 30 such intelligent computing centers are under construction or in the planning stage nationwide.This raises a critical question: Can the power grid cope?Utility Power Outage: The Unbearable Burden for AI Computing PowerWhen power cuts happen in regular offices, staff can only suspend work for half a day, with losses capped at one day’s payroll. For e-commerce platforms, a multi-hour outage means interrupted orders and lost sales revenue. Yet an interruption during AI training incurs far greater losses: wasted time, massive capital expenditure, and model outcomes that may never be reproduced.A single training run of a trillion-parameter large model costs between USD 5 million and 20 million, with training cycles commonly measured in weeks. If utility power fails on the 15th day of training, and the diesel generator set fails to start and carry the load in time after the UPS sustains power for 15 minutes, all prior work will be wasted. Training progress is lost, checkpoints may become corrupted, and restarting the training will cost tens of millions of US dollars.This does not even include hidden costs such as idle GPU clusters, liquidated damages for computing power leasing contracts, and eroded customer trust.This explains why every top-tier data center worldwide treats diesel generator sets as the “last line of defense” and requires compliance with Tier IV standards: automatic startup and load connection within 15 seconds after utility power failure, a minimum 12-hour fuel reserve, and annual availability of no less than 99.995%
III. Diesel Generator Sets: The Only Solution for Non-Stop Data Center Operation
Some may ask: Why not use energy storage batteries to replace diesel engines? The answer lies simply in duration. A 20 MW UPS battery system for data centers typically provides only 10 to 15 minutes of backup power. This 15-minute window is reserved for diesel generator sets to start and synchronize with the load. If this window is exceeded and the batteries drain out, servers shut down abruptly, triggering a data disaster.
By contrast, diesel generator sets can produce continuous power for hours or even days as long as diesel fuel remains in the storage tank. As of 2026, no technology can fully replace diesel generator sets in terms of both cost-effectiveness and reliability. They remain the only mature, scalable long-duration emergency power source available for data centers.
More importantly, supportive policies are being rolled out. In July 2026, the National Energy Administration issued clear requirements for constructing emergency microgrids in disaster-prone regions, mandating the deployment of diesel generator sets. The official notice dated July 20 explicitly states: “Equip necessary facilities including energy storage systems and diesel generator sets.”
Driven by industrial standards and national policies alike, diesel generator sets are shifting from “recommended configuration” to “mandatory requirement”.IV. Domestic Substitution: An Exploding Market Window Worth BillionsFor a long time, foreign brands have monopolized 90% of China’s high-power diesel engine market for data centers, with the localization rate standing at only 17%.Nevertheless, a fundamental shift is underway in 2026.First, delivery lead times have extended. Due to global supply chain volatility, the lead time for high-power units from foreign brands has lengthened from the original 12–16 weeks to more than 30 weeks. Data center construction cannot afford such delays, and domestic manufacturers are rapidly filling the supply gap.Second, breakthroughs have been achieved in independent technologies. Chinese power brands represented by Shanghai Diesel Engine, Yuchai and Weichai have approached internationally advanced levels in key indicators including high power output, high reliability and low emissions. Their products fully meet Tier III and above requirements for data centers.Third, there is a remarkable cost advantage. For units of equivalent power rating, the overall procurement and maintenance costs of domestic alternatives are 30%–40% lower than foreign counterparts. For hyperscale data centers equipped with 10 to 20 units, the savings can amount to tens of millions of RMB.Industry institutions forecast that in 2026, the market size of diesel generator sets for data centers in China will exceed 8 billion RMB, maintaining a compound annual growth rate of over 25% in the next three years. The dividend window for domestic substitution is fully opening.V. Is Your Data Center Ready for the Power Test in the AI Era?The competition in AI computing power is essentially a competition in power assurance capability.If utility power fluctuates frequently due to extreme weather; if you are planning or expanding an intelligent computing center; if your diesel generator sets are outdated low-power equipment —You are facing not merely operational risks, but strategic risks.In an era where large-model AI training is irreversible and computing assets are valued at millions, diesel generator sets are no longer neglected backup units gathering dust in computer rooms.
