China builds massive 800-megawatt AI data center campus to rival US Stargate project

China is building an 800MW AI data center campus in Inner Mongolia that could challenge the economics of America's Stargate project, according to a new report from SemiAnalysis. Envision has built the first 120 MW of Galaxy AI data center campus in less than a year, a cost the researchers put at just one-fifth of comparable US projects, after visiting the site in September.

But getting the buildings up is only half of the battle. AI data centers need enormous amounts of electricity, and Envision is taking an unusual route to secure it— building its own wind farms and battery storage alongside the computing facility.

While US developers are turning to on-site gas turbines to work around grid constraints, Envision is building its data center alongside wind farms, battery storage, and dedicated power infrastructure. Galaxy is located in Ulanqab, Inner Mongolia, and is being developed across four phases for two unnamed internet companies. …
