Ulanqab: China's Bet That AI's Real Bottleneck Isn't Chips, It's the Grid

How off-grid microgrids are accelerating China’s data center expansion inside the massive Inner Mongolia AI cluster.

On August 6, 2026, a huge new facility switched on in a stretch of grassland in Inner Mongolia, a region better known for potatoes than for silicon. It’s called Star River (Xinghe), and the building is the size of twenty football fields. It’s designed to hold up to a million AI accelerators working together, with a theoretical output of 100 million PFLOPS. Based on what its builders have disclosed, it’s one of the largest single AI data center facilities in the world.

The city around Star River is Ulanqab. A few years ago, it was best known for out-migration and potato farming. Today, it is one of the fastest-growing AI computing clusters in the Asia-Pacific region. In June, DeepSeek, fresh off a RMB 50 billion funding round, announced plans to build a 1-gigawatt data center there. That’s just one of 89 data center projects that had signed on to Ulanqab by the end of June 2026, together representing more than RMB 500 billion in committed investment.

The obvious question is: why here? The easy explaination is cheap land and generous local subsidies. The real answer has more to do with a deliberate choice: China has decided that electricity, not chips, is the binding constraint on the AI race, and started treating power generation as part of the data center itself, rather than something you queue up for. None of this makes chips irrelevant; they still matter enormously. But once compute scales into the hundreds of thousands, even millions, of accelerators, keeping them fed with electricity becomes just as hard a problem as building them in the first place.

The Numbers, Briefly

Ulanqab’s planned and operating data center capacity jumped from 3.3 gigawatts in July 2025 to 12.5 gigawatts by June 2026. That’s not incremental growth. It’s nearly a fourfold increase in eleven months, and more than ten times the region’s live capacity in 2025. For comparison, Goldman Sachs research puts Ulanqab’s total pipeline at three times the entire upcoming data center capacity of Johor, Malaysia, currently the largest data center hub in Asia-Pacific outside China.

The companies building there include almost every heavyweight in Chinese tech.Three of China’s top four data center operators by live capacity, GDS, VNET, and Chindata, have gigawatt-scale projects underway, alongside renewable energy developer Envision. ByteDance, Kuaishou, UCloud, Alibaba, and DeepSeek are separately building their own campuses.

And crucially, the demand looks real, not speculative. Utilized capacity in Ulanqab grew more than 70% year-on-year, while live computing power reached 165 EFLOPS by June 2026, equivalent to about 5-7% of China’s entire utilized data center capacity, from a single prefecture-level city. VNET’s campuses there have gone from delivery to majority utilization within a few quarters, a ramp-up speed that suggests customers were waiting for the capacity, not the other way around.
