SemiAnalysis tours Inner Mongolia's 'China Stargate': 120MW built in a year at 1/5 US cost

SemiAnalysis visited the Galaxy datacenter campus in Ulanqab, Inner Mongolia — a planned 800MW wind-powered site comparable to Stargate Abilene. Key findings:
- The first 120MW phase was delivered within a year at roughly one-fifth of US construction costs; all four phases are built-to-suit for two internet giants.
- The campus is owned by Envision Group (100GW+ wind turbines installed globally) and features a 5MW SST-native 800V DC pilot plus a cooling design with no central chillers.
- The surrounding high-tech zone had 30,000 construction workers across 22 datacenter projects, keeping costs falling despite less modular construction.
- Inner Mongolia is China's fastest-growing AI datacenter region with none of the anti-datacenter backlash seen in West Texas.
Dan Jeffries frames it bluntly: China isn't pausing datacenters or pacing the frontier — it's going full speed ahead.
