Chinese Companies Pledge 12.5 Gigawatts in Ulanqab AI Hub as Water and Coal Risks Loom

Summary

  • Nearly 100 data centers have opened or started construction in Ulanqab since 2016, with more than 70% of the city’s 12.5-gigawatt pledged AI capacity announced in the past year.
  • Cheap power, cold weather and proximity to Beijing are drawing builders, while two fiber links cut latency to under five milliseconds—making the city viable for both AI training and inference.
  • DeepSeek, ByteDance, Alibaba and Xiaohongshu are increasingly building their own infrastructure instead of renting cloud compute, signaling a broader catch-up by Chinese AI firms on physical capacity.
  • Water is the main constraint: Ulanqab gets only about 14 inches of rain annually, and the local utility last month shut several waterworks for seven hours nightly to ease peak demand.
  • Inner Mongolia’s boom also fits Beijing’s push to absorb excess wind and solar output, but about 37% of Ulanqab’s electricity still comes from coal, complicating claims of a clean AI buildout.
