SemiAnalysis visits an Inner Mongolia campus planned for up to 800 megawatts of AI capacity

SemiAnalysis reports that Envision Group's Galaxy campus in Ulanqab is planned for up to 800 megawatts of IT capacity, with a first 120 megawatt phase delivered in August 2026, within a year. It draws on 420 megawatts of installed wind capacity and is piloting a solid-state transformer and 800 volt DC power in one 5 megawatt hall. The full campus is expected by the end of 2027.

Why it matters: It shows China building data centers at Stargate scale on cheap wind power, even as chip access stays limited.
