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. The completed campus is planned to provide up to 800MW of IT capacity by the end of 2027, putting it closer to the approximately 820MW of critical IT capacity at the Stargate campus in Abilene, Texas.

Envision is building its own power supply for Galaxy rather than leaving everything to the local grid. So far, the company has installed more than 100GW of wind turbines and wants its wind farms to provide over 60% of the electricity needed by the campus’s first two phases. Those farms, located about 80 kilometers apart, have a combined capacity of 420MW.
