Phase I of a large single-site AI compute cluster in Huailai County, Zhangjiakou
has entered full operation, deploying more than 200,000 servers, many used by
domestic internet firms for large-model training and inference. The cluster
Reportedly consumes over 1,000,000 kWh per hour (≈1,000 MW) at run-rate.
Zhangjiakou’s developable wind capacity exceeds 40 GW, supplying abundant green
power to the compute site. A nearby compute center also commissioned a new
machine-hall in May. Data show China’s compute centers are estimated to consume
170 billion kWh in 2025, about 1.6% of national power use, while green power
trading volume is estimated at 328.5 billion kWh in 2025. Industry participants
expect coordinated national deployment of green power and compute during the
15th Five-Year Plan period to expand upstream and downstream industrial-chain
opportunities.
